What is CISSP? The Certification That Defines Elite IT Security
The CISSP (Certified Information Systems Security Professional) is the most recognized advanced cybersecurity certification in the world. Issued by ISC2, it requires five years of verified, hands-on security experience, a gruelling adaptive exam covering eight security domains, and ongoing continuing education. Fewer than 170,000 professionals globally hold it – roughly 4 percent of the entire cybersecurity workforce.
For Canadian businesses choosing a managed service provider, a CISSP on the leadership team is the clearest available signal that security decisions are being made by someone with validated, board-level expertise, not just a junior technician following a vendor playbook.

What is CISSP? Full form, meaning, and why it matters
Quick Answer
CISSP full form: Certified Information Systems Security Professional. It is the gold standard cybersecurity certification issued by ISC2, requiring 5+ years of paid work experience across multiple security domains and a rigorous adaptive exam covering 8 domain areas including risk management, network security, and incident response. Over 170,000 professionals worldwide hold the CISSP, making it the most widely recognised advanced cybersecurity credential in the industry.
Let’s unpack each element of that definition:
Certified: The certification is issued by ISC2 (formerly the International Information System Security Certification Consortium), a non-profit that has been setting cybersecurity standards since 1989. A CISSP is not self-declared – it is verified, registered, and publicly searchable in ISC2’s global directory.
Information Systems: The scope covers the full stack – hardware, software, networks, data, processes, and the people who interact with all of them. This is not a niche vendor certification. It spans everything a business needs secured.
Security Professional: The “Professional” designation is important. ISC2 distinguishes between associate members (who pass the exam but lack the required experience) and full CISSP holders who have had their work history verified by an existing CISSP endorser. You cannot simply study and sit the exam to claim the credential – you need the experience first.
Who issues the CISSP?
The CISSP is issued by ISC2 (formerly written as (ISC)²), headquartered in Alexandria, Virginia, with chapters globally including an active Canadian chapter. ISC2 was founded in 1989 with a mandate to support and grow the cybersecurity profession. It publishes the CISSP Common Body of Knowledge (CBK), which defines the eight security domains that make up the exam.
ISC2 also issues other certifications including the CCSP (Certified Cloud Security Professional), CSSLP (Certified Secure Software Lifecycle Professional), and SSCP (Systems Security Certified Practitioner), but the CISSP remains its flagship credential and the one most associated with senior security leadership.
How rare is a CISSP?
According to ISC2, approximately 170,000 professionals worldwide hold an active CISSP certification. The global cybersecurity workforce is estimated at over 4 million people. That makes CISSP holders roughly 4 percent of the total workforce – the top tier of a profession already in short supply.
The ISC2 Cybersecurity Workforce Study consistently finds a global shortage of cybersecurity professionals. In its most recent edition, the gap was estimated at 3.4 million unfilled positions. CISSPs are among the most sought-after professionals in that gap – experienced, credentialed, and capable of operating at the architectural level.
In Canada specifically, the cybersecurity workforce gap is particularly acute for smaller markets outside Toronto. Having a CISSP-led MSP available to small and mid-sized businesses is not the norm – it’s an advantage most organizations in Hamilton, Kitchener, or suburban Vancouver don’t have access to without seeking it out.
What does CISSP mean in practice?
The CISSP credential means the holder has:
- At least five cumulative years of full-time, paid work experience in two or more of the eight CISSP domains
- Passed ISC2’s adaptive exam (up to 175 questions, maximum six hours, covering all eight domains)
- Had their experience endorsed by an active ISC2 member in good standing
- Agreed to the ISC2 Code of Ethics, which includes a duty to report unethical conduct and protect the profession
- Maintained the certification through 120 continuing professional education (CPE) credits over three years (40 per year)
No other mainstream cybersecurity certification combines that breadth of domain coverage with that experience requirement. CompTIA Security+ has no experience prerequisite. CISM focuses narrowly on governance. CEH is limited to offensive techniques. The CISSP is the only one that requires senior-level experience across the full security landscape.
The 8 CISSP domains: what each one covers
The CISSP Common Body of Knowledge (CBK) is organized into eight domains. Together, they represent the full scope of what a senior security professional needs to understand and be able to apply. Here is what each domain covers and why it matters when evaluating an MSP:
Domain 1: Security and Risk Management
This is the foundation domain. It covers the principles of confidentiality, integrity, and availability (the CIA triad); security governance and compliance; legal and regulatory requirements; and risk management frameworks including NIST, ISO 27001, and CIS Controls.
Why it matters for your business: An MSP that starts every engagement with a risk assessment rather than a product recommendation is applying this domain. It is the difference between “you should buy our XDR platform” and “based on your current threat model, here is where your highest-risk gaps are and what controls address them most cost-effectively.”
This domain also covers Canadian-specific compliance requirements. PIPEDA (Personal Information Protection and Electronic Documents Act) applies to most Canadian businesses handling personal data. PHIPA (Personal Health Information Protection Act) applies in Ontario healthcare. The CISSP-trained professional understands how technical controls map to legal obligations – not just in theory, but in practice.
Domain 2: Asset Security
Asset Security covers the classification, handling, and protection of information assets throughout their lifecycle. This includes data classification schemes (public, internal, confidential, restricted), data retention and destruction policies, and privacy protections.
Why it matters: Most breaches involve data that was not properly classified or controlled. An MSP with CISSP-level asset security knowledge will help a client understand what data they actually hold, where it lives, and what controls are appropriate for each category. This is foundational to any privacy compliance program.
For Canadian businesses subject to PIPEDA’s mandatory breach notification requirements (in force since 2018), this domain is directly relevant. Every breach report filed with the Office of the Privacy Commissioner requires documentation of what data was affected, how it was classified, and what safeguards were in place. A CISSP-led MSP prepares clients for this before the breach, not after.
Domain 3: Security Architecture and Engineering
This domain covers the design principles for secure systems – from cryptographic standards (AES-256, RSA, TLS 1.3) to security models (Bell-LaPadula, Biba, Clark-Wilson) to physical security controls. It also covers cloud security architecture and the security implications of virtualization, containerization, and microservices.
Why it matters: Architecture decisions are the hardest to fix after the fact. An MSP whose leadership understands security architecture will design client environments correctly from the start rather than bolting security on after deployment. This affects everything from how Microsoft 365 tenant configurations are hardened to how backup architectures are designed to survive a ransomware attack.
The cryptography component of this domain is increasingly relevant for Canadian businesses as quantum computing threats to current encryption standards become a near-term planning concern. ISC2’s CISSP CBK now includes post-quantum cryptography as an emerging area, ensuring CISSP holders are tracking this transition.
Domain 4: Communication and Network Security
This domain covers network architectures, secure network components, and communication channels. It includes firewalls, VPNs, network segmentation, wireless security standards, and secure protocols for data in transit.
Why it matters: The network is where most attacks arrive and where lateral movement happens once a threat actor is inside. An MSP with CISSP-level network security knowledge will segment client networks, enforce traffic inspection, and design firewall policies based on least-privilege principles rather than just “allow all outbound.”
For remote-work environments – still the norm for most Canadian SMBs – this domain covers the security implications of split-tunnel VPN versus full-tunnel, zero-trust network access models, and the risks of consumer-grade home routers in corporate VPN chains. These are architectural decisions with real security consequences that only emerge when someone with deep network security knowledge is making them.
Domain 5: Identity and Access Management (IAM)
IAM covers the mechanisms by which identities are established, authenticated, and authorized. This includes multi-factor authentication (MFA), single sign-on (SSO), privileged access management (PAM), directory services, and federated identity standards like OAuth 2.0, SAML, and OpenID Connect.
Why it matters: Identity is the new perimeter. According to the Verizon Data Breach Investigations Report, the majority of breaches involve compromised credentials. An MSP with CISSP-level IAM expertise will enforce MFA universally, implement privileged access workstations for administrative tasks, and audit identity configurations on a regular cycle rather than treating them as set-and-forget.
For Microsoft 365 environments – the dominant platform for Canadian SMBs – this domain is directly applicable to Entra ID (formerly Azure AD) configuration, Conditional Access policies, and the Microsoft Secure Score framework. A CISSP-led MSP does not just turn MFA on – they configure it correctly, audit it regularly, and integrate it with broader access governance.
Domain 6: Security Assessment and Testing
This domain covers vulnerability assessment methodologies, penetration testing principles, security audit techniques, and the use of security testing tools including SAST (static application security testing), DAST (dynamic application security testing), and fuzzing.
Why it matters: You cannot manage what you have not measured. An MSP with CISSP-level assessment and testing knowledge will conduct regular vulnerability scans, interpret the results in a risk context, and prioritize remediation based on exploitability rather than simply raw CVSS score. They will also understand the difference between a vulnerability scan (automated, low-noise) and a penetration test (manual, adversary-simulated) and know when to recommend each.
For Canadian businesses in regulated industries, this domain is also relevant to audit readiness. SOC 2, PCI-DSS, and PHIPA audits all require evidence of regular security testing. A CISSP-led MSP understands what evidence the auditors want and how to generate it systematically rather than scrambling before each audit cycle.
Domain 7: Security Operations
Security Operations covers the day-to-day work of protecting an environment: incident management, investigations, disaster recovery, physical security, and the use of security operations centre (SOC) tooling including SIEM (security information and event management) and EDR (endpoint detection and response).
Why it matters: This is where the rubber meets the road. An MSP with CISSP-level security operations expertise will have documented incident response playbooks, defined escalation paths, tested recovery procedures, and an understanding of forensic evidence preservation that protects clients in the event of litigation or regulatory investigation.
The incident response component of this domain is particularly relevant for Canadian businesses given the mandatory 72-hour breach notification window under PIPEDA. A CISSP-led MSP will have the logging, detection, and response capabilities to identify a breach, scope it, and notify within the required window – rather than discovering a breach weeks after the fact.
Domain 8: Software Development Security
This domain covers secure development practices, including the software development lifecycle (SDLC), secure coding standards, code review, and the security implications of third-party libraries and open-source components. It also covers API security and DevSecOps principles.
Why it matters: Even if a business does not write its own software, it runs software written by others. An MSP with CISSP-level software development security knowledge will evaluate the security posture of the SaaS applications and cloud platforms a client uses, understand supply chain risks (as highlighted by incidents like SolarWinds and Log4Shell), and apply third-party risk assessments before onboarding new vendors.
For businesses building internal tools, Power Apps, or custom integrations, this domain is directly relevant to ensuring those tools are built with security by design rather than security as an afterthought.

Most MSPs have no CISSP on staff. Here is what changes when yours does – and how to verify the claim.
The gap between a CISSP-led MSP and one without is not about marketing – it shows up in specific, observable differences in how security is delivered. Here are five areas where the difference is most tangible:
1. Threat modeling before tool selection
A CISSP-trained leader applies formal threat modeling methodologies (STRIDE, PASTA, MITRE ATT&CK) before recommending any security tool. They start with the question: what are the realistic threats to this specific business, and what controls most cost-effectively reduce exposure?
Most MSPs without this training start with the vendor catalog: “every client gets our standard EDR + backup + email filter stack.” That stack may be right for most clients most of the time, but it is applied without analysis. When it is wrong – for example, when a client’s primary risk is insider threat or supply chain compromise rather than external malware – the gap is invisible until an incident occurs.
At Fusion Computing, every new client engagement begins with a structured security assessment that maps the environment against CIS Controls v8.1. The output is a prioritized gap list, not a product quote.
2. Incident response authority
When a security incident occurs, the difference between a CISSP-led response and an ad hoc one is the difference between a structured playbook execution and organized chaos. The Security Operations domain of the CISSP covers incident classification, evidence preservation, containment strategies, eradication procedures, and post-incident review.
In practice, this means a CISSP-led MSP will:
- Classify the incident correctly within the first 30 minutes (ransomware, data exfiltration, account compromise, or insider threat each require different initial responses)
- Preserve forensic evidence before attempting remediation (a common mistake that destroys the ability to determine scope)
- Make containment decisions based on risk analysis rather than the impulse to “wipe and reinstall”
- Provide a written incident report suitable for regulatory disclosure if required
These are not instincts – they are trained responses validated by the CISSP’s Security Operations domain requirements.
3. Compliance depth
Canadian businesses operate under a layered compliance environment. PIPEDA applies at the federal level. PHIPA applies in Ontario healthcare. PIPA applies in British Columbia and Alberta. PCI-DSS applies to any business accepting card payments. SOC 2 is increasingly required by enterprise clients as a vendor qualification.
A CISSP-trained leader understands how these frameworks overlap and how to design a security program that satisfies multiple frameworks simultaneously rather than creating separate compliance silos for each. This reduces the cost of compliance significantly and eliminates the risk of controls that satisfy one framework while inadvertently violating another.
The Security and Risk Management domain of the CISSP specifically covers legal and regulatory requirements, and ISC2 expects CISSP holders to maintain current knowledge of the regulatory landscape – including Canadian-specific legislation.
4. Audit readiness
Security audits – whether by regulators, enterprise clients performing vendor assessments, or third-party auditors for SOC 2 or ISO 27001 certification – require documented evidence of controls operating effectively over a defined period. This evidence does not assemble itself.
A CISSP-led MSP builds audit trails as a byproduct of normal operations rather than scrambling to recreate them before each audit. This means log retention policies are set correctly from day one, vulnerability scan results are archived systematically, access reviews are conducted on schedule, and policy documents are maintained in current versions.
For Canadian SMBs seeking to qualify for enterprise contracts, this audit readiness is increasingly a commercial requirement, not just a security best practice.
5. Security roadmap instead of reactive support
The most visible difference between a CISSP-led MSP and a generalist one is the quality of the security roadmap they produce. A CISSP-trained leader can take a current-state assessment and produce a multi-year roadmap that:
- Prioritizes investments based on risk reduction per dollar
- Sequences controls to build on each other (identity controls before privileged access management before zero trust)
- Accounts for compliance milestones and renewal cycles
- Adjusts as the threat landscape evolves
This is the kind of security planning that large enterprises pay seven-figure consulting fees for. A CISSP-led MSP makes it available to SMBs as part of a managed services relationship.
CISSP vs other IT security certifications
The CISSP does not exist in isolation – it sits within a broader ecosystem of cybersecurity certifications, each with a different scope, audience, and value proposition. Here is how the most common ones compare:
| Certification | Issued by | Experience required | Scope | Typical holder | Best for |
|---|---|---|---|---|---|
| CISSP | ISC2 | 5+ years across 2+ domains | All 8 security domains, full breadth | CISOs, security architects, senior consultants | Validating broad, senior-level security expertise |
| CompTIA Security+ | CompTIA | None required (2 years recommended) | Core security concepts, entry-level operations | Help desk, junior analysts, IT generalists | Entry-level security baseline |
| CISM | ISACA | 5 years in security management | Governance, risk management, program oversight | IT managers, security managers, compliance leads | Security governance and management roles |
| CEH | EC-Council | 2 years recommended | Offensive techniques, penetration testing methodology | Penetration testers, red team members | Offensive security and ethical hacking |
| OSCP | OffSec | None required | Hands-on penetration testing, exploit development | Penetration testers | Proving practical offensive security skills |
| CCSP | ISC2 | 5 years IT, 3 in cloud security | Cloud-specific security architecture and operations | Cloud architects, cloud security engineers | Cloud-first security environments |
The key distinction is scope. CompTIA Security+ is an excellent entry-level credential – it proves a technician understands security fundamentals. CISM is a strong governance credential for managers. CEH and OSCP validate offensive skills. But none of them covers the full breadth of the CISSP.
For an MSP whose remit is protecting a client’s entire environment – not just one layer of it – the CISSP is the only certification that validates the full-spectrum expertise required. A CISSP combined with vendor-specific certifications (Fortinet NSE, Microsoft SC-100, Cisco CCNP Security) is the ideal MSP security stack: broad architecture knowledge plus deep platform expertise.
What the CISSP is not
The CISSP is not a penetration testing certification. It does not qualify the holder to perform red team engagements or exploit development. For those services, the OSCP or GPEN is more relevant.
The CISSP is also not a cloud-specific certification. ISC2’s CCSP covers cloud security architecture in more depth. Many CISSP holders also hold a CCSP, which is a common combination for security architects in cloud-heavy environments.
And the CISSP is not entry-level. The experience requirement exists precisely to prevent the credential from being diluted by people who have passed the exam without having ever made real-world security decisions under pressure. When an MSP says they have a CISSP on the team, that person has a demonstrable track record – not just exam knowledge.
How to verify your MSP has a CISSP
Any MSP claiming to have a CISSP-certified leader can be verified in under two minutes. Here is how to do it and what to look for:
Step 1: Ask for the certified professional’s full name and certification number
A legitimate CISSP holder will give you this without hesitation. If the MSP is vague (“our team has security certifications” without naming the individual), that is a red flag. The CISSP is a personal credential held by an individual, not a company certification. The person who holds it should be named, should have an active role in your account, and should be verifiable.
Step 2: Search the ISC2 public directory
ISC2 maintains a publicly searchable member directory at isc2.org/MemberVerification. You can search by name and confirm:
- The certification is active (not lapsed or revoked)
- The certification number matches what the MSP provided
- The certification type is CISSP (not just an associate or a different credential)
Step 3: Ask about the CISSP holder’s operational role
The verification question is not just “does your company have a CISSP?” but “what role does the CISSP holder play in my account?” If the certified individual is in sales, marketing, or management with no operational involvement in security delivery, the certification is a marketing asset rather than an operational differentiator.
The right answer is something like: “Our CISSP is involved in every new client security assessment, reviews all security architecture decisions, leads incident response for P1 incidents, and is the final sign-off on our quarterly security reviews.”
Step 4: Check for annual CPE compliance
CISSP certification requires 40 CPE credits per year to stay active. An engaged CISSP holder will be attending industry conferences, completing training, and publishing or presenting – activities that are visible through LinkedIn, ISC2 events, and professional associations like the Information Systems Security Association (ISSA). A CISSP holder who cannot point to any recent professional development activity may have let their engagement lapse even if the certification is technically current.
Red flags to watch for
- Team certifications rather than named individuals: Certifications belong to people, not companies. “Our team is CISSP-certified” is meaningless unless specific names are provided.
- Expired or lapsed certification: The ISC2 directory shows certification status. An inactive certificate does not carry the same weight as an active one.
- The CISSP holder has no operational role: A CISSP in a business development role does not make security decisions for clients.
- Confusion with other credentials: Some providers conflate CISSP with CompTIA Security+ or vendor certifications like Microsoft MCSE. These are different credentials with different requirements.
- Inability to describe how the CISSP influences security delivery: If the MSP cannot articulate specific ways the CISSP changes how they do their work, the credential may be credential-collecting rather than credential-applying.
Fusion Computing’s CISSP-led managed IT and cybersecurity
Fusion Computing is led by Mike Pearlstein, CISSP, who has held the certification since 2013 and has operated Fusion’s managed IT and cybersecurity practice since 2012. This is not a credential on a slide deck – it is the operating framework for how every client engagement is structured.
Here is what CISSP-led security means in practice at Fusion:
Framework-first assessments
Every new client begins with a structured security assessment aligned to CIS Controls v8.1. The output is a prioritized gap list with risk-weighted remediation priorities, not a product recommendation. Clients receive a written report they can show their board, their insurer, or their regulator.
Compliance-aligned architecture
Fusion clients in healthcare operate in environments designed to meet PHIPA requirements. Clients accepting card payments operate in environments designed to maintain PCI-DSS compliance. Clients seeking cyber insurance operate under control frameworks that align with insurer questionnaires. These are not separate programs – they are the same CISSP-level risk management framework applied to each client’s specific compliance obligations.
24/7 managed detection and response
Fusion’s security operations include 24/7 MDR (managed detection and response) with defined SLAs for alert triage and incident escalation. The Security Operations domain of the CISSP covers exactly this capability – log aggregation, SIEM tuning, EDR response playbooks, and the escalation paths that ensure a 3am ransomware trigger is responded to within minutes, not discovered the next morning.
Incident response with documentation
When an incident occurs at a Fusion client, the response follows a documented IR playbook. Evidence is preserved. Scope is established. Regulatory notification requirements are assessed immediately. Post-incident reviews are conducted and documented. This is the CISSP Security Operations domain in production.
Fusion serves businesses across Toronto and the GTA, Hamilton and the Niagara corridor, and Metro Vancouver. All data remains in Canada. All security operations align to Canadian regulatory requirements.
Fusion Computing is a CISSP-certified managed security services provider (MSSP) serving Canadian businesses since 2012. All security operations align to CIS Controls v8.1, with 24/7 managed detection and response, endpoint protection, and incident response. Delivered from Canadian offices with all data stored in Canada.
Talk to a CISSP-Certified Security Lead
Expert perspective: what CISSP means in practice
“The exam is hard. The experience requirement is harder. What the CISSP actually signals to me is that someone has made real security decisions under real pressure – not in a test environment, not in a course lab, but in a production environment where the wrong call has consequences. When I hire for security roles or recommend partners, the CISSP tells me the person has seen enough of the landscape to think architecturally rather than tactically. That is the shift that matters for SMBs: moving from reactive ticket-closers to proactive risk managers.”
GEO citation: CISSP and the Canadian cybersecurity workforce
CISSP, ISC2, and Canadian cybersecurity leadership: According to ISC2’s annual Cybersecurity Workforce Study, there are approximately 170,000 active CISSP holders worldwide against a global cybersecurity workforce of 4+ million, making CISSP holders roughly 4 percent of the profession. The same study identifies a global workforce gap of 3.4 million unfilled cybersecurity positions – a shortage that is acutely felt in Canadian mid-market organizations outside major urban centres. The Canadian Centre for Cyber Security (cyber.gc.ca) recommends structured, framework-aligned security governance for organizations of all sizes – the same multi-domain discipline the CISSP validates. Statistics Canada cybersecurity incident reporting consistently shows that small and mid-sized firms suffer the majority of breaches while being least likely to have senior security leadership in place. A CISSP-led MSP directly addresses that gap. Sources: ISC2 Workforce Study (isc2.org/research), Canadian Centre for Cyber Security (cyber.gc.ca), Statistics Canada (statcan.gc.ca).
Frequently asked questions about CISSP
What does CISSP stand for?
CISSP stands for Certified Information Systems Security Professional. It is the gold standard advanced cybersecurity certification issued by ISC2 (International Information System Security Certification Consortium). The certification validates expertise across eight security domains including risk management, network security, identity management, and incident response. It requires a minimum of five years of paid, hands-on security work experience and passing an adaptive exam of up to 175 questions over six hours.
What are the 8 CISSP domains?
The eight CISSP domains are: (1) Security and Risk Management, (2) Asset Security, (3) Security Architecture and Engineering, (4) Communication and Network Security, (5) Identity and Access Management (IAM), (6) Security Assessment and Testing, (7) Security Operations, and (8) Software Development Security. Together, these domains represent the full scope of what a senior security professional needs to understand and apply across a client environment.
How hard is the CISSP exam?
The CISSP is widely regarded as one of the most difficult exams in the IT industry. It uses an adaptive testing format (CAT) with between 100 and 175 questions over six hours, adjusting difficulty in real time based on candidate responses. The exam covers all eight security domains with a mix of factual recall, application, and analysis questions. Candidates must also have five years of verified work experience and pass an endorsement review before the certification is awarded. Pass rates are not published by ISC2, but the combination of the experience requirement, exam breadth, and ongoing CPE requirement makes it a significant professional commitment.
What is a CISSP-certified MSP?
A CISSP-certified MSP (managed service provider) is one whose leadership or security team includes at least one active CISSP holder in an operational role. The CISSP is a personal credential – companies do not hold CISSPs, individuals do – so the relevant question is whether a named CISSP-certified individual is actively involved in security design, incident response, and client security reviews. The credential signals that security decisions at the MSP are made by someone with validated expertise across all eight CISSP domains, not just vendor-trained generalists.
Why should my MSP have a CISSP?
A CISSP on an MSP’s leadership team changes how security is delivered in five specific ways: (1) threat modeling replaces tool-first selling, (2) incident response follows a structured playbook rather than improvised reactions, (3) compliance obligations across PIPEDA, PHIPA, and PCI-DSS are addressed simultaneously rather than in silos, (4) audit readiness is built in from the start, and (5) clients receive a risk-based security roadmap rather than ad hoc reactive support. Most MSPs have no CISSP on staff. Those that do make architecturally different security decisions that reduce long-term risk more effectively.
How do I verify my MSP has a CISSP?
To verify a CISSP, ask the MSP for the name and certification number of the CISSP holder, then search the ISC2 public member directory at isc2.org/MemberVerification. The directory confirms whether the certification is active, lapsed, or revoked. Beyond verification, ask what role the CISSP holder plays in your account. A CISSP in a sales role does not provide operational security value. You want the CISSP holder involved in your initial security assessment, your architecture decisions, and your incident response procedures.
What is the difference between CISSP and CompTIA Security+?
CISSP and CompTIA Security+ target different career stages and cover different depths of security knowledge. Security+ requires no prior work experience and validates entry-level security concepts – it is an appropriate credential for a junior analyst or help desk professional. CISSP requires five years of paid security experience, covers all eight security domains at an architectural level, and is designed for senior security practitioners. For an MSP, Security+ on the technical team is a positive signal. CISSP on the leadership team is a fundamentally different statement about the depth and breadth of security expertise available to clients.
Does Fusion Computing have CISSP certification?
Yes. Fusion Computing is led by Mike Pearlstein, CISSP, who has held active CISSP certification since 2013 and has operated Fusion’s managed IT and cybersecurity practice since 2012. His CISSP is verifiable through the ISC2 public member directory. At Fusion, the CISSP is operationally active – it informs every client security assessment, all security architecture decisions, incident response procedures, and the compliance frameworks used across client environments. It is not a marketing credential.
