Cybersecurity Hamilton — the short answer
Fusion Computing is a CISSP-led managed security provider serving Hamilton and the Golden Horseshoe since 2012. We protect manufacturers, healthcare suppliers, and professional firms with Huntress 24/7 managed detection, SentinelOne endpoint protection, Microsoft 365 with MFA and conditional access, and CIS Controls v8.1 — plus OT/IT segmentation for Hamilton’s steel and industrial base. Canadian-owned, data kept in Canada.
Cybersecurity in Hamilton is different from anywhere else in Canada
Hamilton’s economy creates a cybersecurity threat profile unlike any other Canadian city. Advanced manufacturing along the Bayfront runs operational technology (OT) and industrial control systems that were never designed to be internet-connected. Hamilton Health Sciences and St. Joseph’s Healthcare hold PHIPA-regulated patient data at scale. McMaster University spin-offs carry valuable IP. The Port of Hamilton and John C. Munro International Airport require 24/7 operational continuity. Every one of these sectors demands security expertise that a generalist Toronto MSSP cannot provide.
According to IBM’s 2025 X-Force Threat Intelligence Index, manufacturing has been the single most-targeted industry four consecutive years. Industrial sector breaches average CA$8.39 million per incident. For Hamilton’s steel, fabrication, and automotive parts manufacturers, that number is not abstract.
“Every Hamilton manufacturer I talk to knows they have an OT network that is partially isolated and partially not. The partial is the problem. We do OT/IT boundary assessments before we deploy anything else, because a flat network connecting a PLC to the business LAN is an open door that no EDR tool closes on its own.” — Mike Pearlstein, CISSP, CEO, Fusion Computing (Hamilton office)
OT/IT convergence: Hamilton’s #1 manufacturing threat vector
Hamilton’s industrial base runs SCADA systems, PLCs, and robotics alongside standard Windows networks. When those environments converge without proper segmentation, a single phishing email can cross the boundary from business email to production floor.
The OT/IT boundary problem
ICS/SCADA systems were not designed for threat detection
Industrial control systems running production lines cannot accept standard EDR agents. Protecting them requires network-level segmentation, OT-aware monitoring, and IEC 62443-aligned architecture that is separate from standard endpoint security.
Ransomware targeting manufacturing
#1 targeted sector four years running
IBM X-Force 2025: manufacturing is the most attacked industry globally. Ransomware groups specifically target OT environments to force ransom payment by threatening production shutdown. Hamilton’s industrial density makes it a concentration risk.
Supply chain attack surface
Tier 2 and Tier 3 suppliers are the entry point
Large OEMs require that their Hamilton-area suppliers pass security assessments. A breach at a Tier 2 parts supplier can shut down an OEM assembly line. Meeting supplier security requirements is now a contract obligation, not a best practice.
The Hamilton economy that shapes its cyber risk
Hamilton is still Canada’s steel city, and that concentration defines its attack surface. The local steel industry — anchored by ArcelorMittal Dofasco, Stelco, and National Steel Car — directly employs more than 10,000 people, with the Hamilton Chamber of Commerce estimating roughly 40,000 more in spinoff jobs (Government of Ontario; Stelco). Those plants run operational technology — PLCs, SCADA, robotics — that ransomware crews target precisely because shutting a production line down is the fastest way to force a payout.
Trade flows through the HOPA Ports network — the ports of Hamilton and Oshawa plus the Thorold Multimodal Hub — which moved 11.46 million tonnes of cargo across 676 vessel calls in the 2024 navigation season, with steel-making commodities making up about 47.5% of the mix and agri-food roughly 31% (HOPA Ports, 2024 results). The freight, warehousing, and field-services firms feeding that supply chain are supply-chain attack targets whose uptime is a security requirement.
On the knowledge side, McMaster University has helped spin out more than 150 companies, and McMaster Innovation Park now hosts roughly 70 firms and 800-plus employees across life sciences, advanced manufacturing, and AI (McMaster Innovation Park). That research IP — the kind that produced a $2.4 billion AstraZeneca acquisition of a McMaster spin-out — is exactly what commercial-espionage and nation-state actors pursue. Add the PHIPA-regulated data held by Hamilton Health Sciences and St. Joseph’s Healthcare, and you have four distinct risk profiles inside one city.
“A generalist provider sees Hamilton as another postal code. We see a steel town with live OT networks, a healthcare corridor under PHIPA, a port supply chain, and university IP — four different threat models that need four different control sets. We start by figuring out which one you actually live in, then build the program around that.” — Mike Pearlstein, CISSP, CEO, Fusion Computing
Five reasons Hamilton cybersecurity is not a Toronto engagement with a different postal code
1. OT/IT segmentation expertise for manufacturers
Standard MSSPs deploy EDR and call it done. Fusion performs OT/IT boundary assessments aligned to IEC 62443, segments PLC and SCADA networks from business LANs, and implements OT-aware monitoring. No other Hamilton-area MSSP advertises this capability.
2. PHIPA compliance for HHS and St. Joe’s suppliers
Healthcare suppliers and referral networks connected to Hamilton Health Sciences and St. Joseph’s must meet PHIPA technical safeguards. Fusion provides a 14-point PHIPA safeguard audit, documented breach-notification runbooks aligned to Ontario IPC timelines, and CIS Controls v8.1 mapping for auditors.
3. McMaster spin-off IP protection
McMaster has helped spin out more than 150 companies, and McMaster Innovation Park now houses roughly 70 firms and 800-plus employees in life sciences, advanced manufacturing, and AI. That research IP is exactly what nation-state and commercial-espionage actors pursue. Fusion protects it with zero-trust access, data loss prevention, and privileged access management for engineering credentials — not a generic antivirus rollout.
4. Port and logistics operational continuity
The HOPA Ports network — Hamilton, Oshawa, and the Thorold Multimodal Hub — moved 11.46 million tonnes of cargo in 2024, roughly half of it steel-making commodities. Freight, warehousing, and field-services firms feeding that supply chain cannot afford downtime or a vendor-impersonation fraud. Fusion builds tested business-continuity and disaster-recovery plans, locks down field laptops with conditional access, and treats operational uptime as a security requirement, not an afterthought.
5. Local Hamilton presence, not a Toronto team with a map
Fusion’s Hamilton office at 64 Hatt St, Dundas means on-site dispatch reaches Hamilton, Stoney Creek, Ancaster, Burlington, and Grimsby in four hours or less. When a security incident needs physical response, we are already here. Toronto MSPs dispatch from the 400 series and quote same-day if you are lucky.

Why Hamilton businesses choose Fusion over a bigger MSSP
-
CISSP-certified leadership on every engagementYour security strategy is designed by Mike Pearlstein, CISSP — not delegated to a junior analyst. The person who builds your controls is the same person you call when something goes wrong.
-
Hamilton office with genuine on-site capability64 Hatt St, Dundas is a working office, not a mailing address. Our team dispatches to Hamilton, Ancaster, Stoney Creek, Burlington, and Grimsby. Four-hour on-site response means something when your production line is down.
-
Manufacturing OT security experienceFusion has assessed and segmented OT environments across Hamilton-area manufacturers. We understand PLC network architecture, SCADA system constraints, and why standard EDR agents cannot be installed on a Siemens S7 controller. Most MSSPs do not.
-
Canadian data residency, 50 Best designationCanadian-owned since 2012. Your logs, backups, and threat data stay in Canada. 50 Best Managed IT in Canada, 2024 and 2025. 93% first-contact resolution. These are audited numbers, not marketing claims.
What Hamilton clients say
“The OT assessment alone was worth the engagement. Fusion found three uncontrolled pathways from our production VLAN to the corporate network that our previous IT provider had missed for two years. They segmented the environment before we even signed off on the full rollout.”
Operations Director
Steel fabrication, Hamilton
“We needed PHIPA documentation to satisfy an HHS supplier audit. Fusion delivered the full 14-point safeguard package and our incident response runbook in three weeks. We passed the audit first time. That was not a coincidence.”
Executive Director
Healthcare services, Dundas
“After the City of Hamilton incident, our CFO asked what our exposure was. Fusion ran a full assessment, showed us the gaps against our insurance requirements, and had us coverage-ready within 45 days. The MFA shortfall that cost the City $5 million — we had the same gap.”
CFO
Professional services firm, Hamilton
Their staff is very professional, reliable and trustworthy, able to handle absolutely all your IT needs and keeping all your data safe and secure. A must have for any business looking for IT solutions.
Truly a blessing to have them by your side and watching your back while you take care of day to day tasks.
Compliance frameworks Fusion maps to for Hamilton clients
Each engagement includes documentation aligned to the frameworks your auditors, insurers, and enterprise clients require.
IEC 62443 (OT Security)
The international standard for industrial automation and control system security. Fusion applies IEC 62443 zone-and-conduit architecture to segment manufacturing OT environments. Required for supplier qualification with many Hamilton-area OEMs.
PHIPA (Healthcare)
Ontario’s Personal Health Information Protection Act governs every clinic, lab, and healthcare supplier connected to Hamilton Health Sciences or St. Joseph’s Healthcare. Fusion maps the required technical safeguards — encryption, access controls, audit logging, and breach-notification procedures aligned to the Information and Privacy Commissioner of Ontario — against CIS Controls v8.1 so your documentation holds up in a vendor security review.
ISO 27001 (Information Security)
Fusion’s CIS Controls v8.1 implementation maps directly to ISO 27001 Annex A controls. For manufacturing clients pursuing ISO 27001 certification as a supplier requirement, our documentation package reduces the audit preparation timeline significantly.
PIPEDA (Privacy)
Canada’s federal private-sector privacy law applies to Hamilton businesses that handle personal information in the course of commercial activity — law firms, accounting practices, brokerages, and logistics operators alike. Fusion implements the safeguards PIPEDA expects (encryption in transit and at rest, MFA, conditional access, DMARC for email, and documented breach response) and keeps the records that demonstrate accountability if a regulator or enterprise client asks.
Cyber Insurance Alignment
The City of Hamilton’s $5 million denial is the benchmark. Insurers now require evidence of MFA, EDR, offline backups, and tested incident response. Fusion delivers documentation that satisfies carrier questionnaires from Chubb, Intact, and Aviva.
CIS Controls v8.1 + NIST CSF
The foundational framework for every Fusion engagement. CIS Controls v8.1 provides 18 prioritized control families; NIST CSF provides the Identify-Protect-Detect-Respond-Recover structure. Both are accepted by Canadian cyber insurers and enterprise procurement teams.
Industries Fusion protects in Hamilton
Five verticals where Hamilton risk profiles are distinct. Each profile below reflects active Hamilton client engagements.
Advanced manufacturing and steel
Hamilton’s manufacturing sector — steel, fabrication, automotive parts, and food processing — runs OT environments that are the primary ransomware target in Canada four years running. Our cybersecurity Hamilton manufacturing engagement starts with an IEC 62443-aligned OT/IT boundary assessment, then deploys Huntress MDR and SentinelOne XDR on business endpoints and OT-aware monitoring on the industrial network. We map controls to ISO 27001 Annex A for OEM supplier qualification requirements.
Healthcare clinics and HHS/St. Joe’s suppliers
PHI breaches are reportable to the IPC of Ontario with a 72-hour window and can result in regulatory action. Our cybersecurity Hamilton healthcare offering includes PHIPA-aligned network segmentation, encrypted EMR backups verified weekly, Huntress MDR and SentinelOne on every clinical endpoint, and a documented 14-point PHIPA safeguard audit. Healthcare suppliers connected to Hamilton Health Sciences or St. Joseph’s who must pass vendor security assessments use our documentation package for that purpose.
A Hamilton multi-site clinic stopped a QakBot infection we detected on day zero after it bypassed their existing endpoint vendor. No PHI exfiltration, no notifiable breach under PHIPA.
McMaster spin-offs and research commercialization
Technology companies commercializing McMaster University research carry IP that nation-state actors specifically pursue. Our cybersecurity Hamilton package for research-based companies deploys zero-trust network access, data loss prevention, endpoint isolation for development environments, and privileged access management for engineering credentials. We include IP classification guidance as part of onboarding to identify what actually needs the highest protection tier.
Law firms and accounting practices
Solicitor-client privilege is destroyed by a ransomware leak. Our cybersecurity services Hamilton for legal and accounting clients ship with Huntress MDR, SentinelOne, encrypted email with DLP for client communications, and a tested incident response runbook aligned to LSUC and CPA Ontario practice standards. Every engagement includes executive tabletop exercises so principals understand their role before a real breach.
Port logistics and field services
Port of Hamilton operations and field services companies with access to customer facilities are supply-chain attack targets. Our cybersecurity services Hamilton for logistics and trades clients lock down field laptops with Huntress MDR, SentinelOne, and conditional access policies that flag impossible-travel from unfamiliar sites. Dispatcher workstations get the same hardened baseline as head-office finance. Operational continuity is built into the incident response plan with pre-staged recovery tools and tested 4-hour on-site response.
A Hamilton-area freight logistics company we protect blocked a vendor-impersonation phishing wave in Q1 2026 targeting their port access credentials. Zero operational incidents.
Cybersecurity pricing for Hamilton businesses
One per-user fee. All tools included. No add-on licensing for EDR, firewall, or password management.
Co-Managed
$130/user/month
Your IT team or internal staff handle day-to-day; Fusion provides SOC monitoring, EDR tooling, and escalation. Ideal for businesses with an existing IT person who needs security backing.
Fully Managed
$180/user/month
Fusion owns everything: monitoring, response, patching, vulnerability management, compliance documentation. Includes OT security assessment for manufacturing clients. All tools included.
A typical 25-user fully managed engagement runs approximately $4,500/month with all tools included. Manufacturing clients with OT scope are quoted based on the number of OT network segments after the boundary assessment.
Who Fusion Hamilton cybersecurity is built for
Hamilton businesses with 10 to 150 employees that do not have a full-time security team. You might be:
- A manufacturer in Stoney Creek or the Bayfront running SCADA or PLC systems on a network that also carries business email and ERP traffic.
- A healthcare clinic in Dundas, Ancaster, or downtown Hamilton that needs PHIPA compliance documentation for an HHS or St. Joe’s supplier audit.
- A McMaster spin-off or life sciences company handling proprietary research data that would have value to a competitor or nation-state actor.
- A law firm or accounting practice in Hamilton that stores client records under PIPEDA and privilege obligations and cannot afford a disclosure event.
- A professional services firm that is being asked to pass a vendor security questionnaire by an enterprise client and does not have the documentation to do it.
If you have outgrown basic antivirus but are not ready for a six-figure security operations center, that is exactly where Fusion fits. Schedule a Consultation.
Cybersecurity Hamilton: common questions
What is OT/IT security and why does it matter for Hamilton manufacturers?
Operational technology (OT) refers to industrial control systems — PLCs, SCADA, HMI — that run manufacturing equipment. IT refers to standard business networks carrying email, ERP, and file servers. Most Hamilton manufacturers have both. When they share a network without segmentation, a ransomware attack entering through a phishing email on the IT side can reach and shut down production equipment on the OT side. Fusion performs IEC 62443-aligned OT/IT boundary assessments and implements zone-and-conduit segmentation to prevent that crossing. Standard MSSPs deploying only EDR do not address this problem.
How fast can Fusion respond to a security incident in Hamilton?
Remote containment starts within minutes. Our SOC isolates the affected endpoint, kills malicious processes, and begins forensic triage immediately. The 1-hour critical response SLA covers remote containment. For on-site work, we dispatch from 64 Hatt St, Dundas and arrive within four hours to Hamilton, Stoney Creek, Ancaster, Burlington, and Grimsby. When a production line is down, the four-hour on-site window is not a promise we make casually.
Does Fusion help Hamilton healthcare organizations with PHIPA compliance?
Yes. Clinics, labs, and suppliers connected to Hamilton Health Sciences and St. Joseph’s Healthcare must meet PHIPA technical safeguards before they can pass a vendor security assessment. Fusion implements encryption, access controls, audit logging, MFA, and documented breach-notification procedures aligned to the Information and Privacy Commissioner of Ontario, then maps the whole program to CIS Controls v8.1 so auditors and procurement teams can verify it. Huntress 24/7 managed detection and SentinelOne endpoint protection cover every clinical device.
What does cybersecurity cost for a Hamilton business?
Co-managed cybersecurity starts at $130/user/month. Fully managed — where Fusion owns monitoring, response, patching, and compliance documentation — is $180/user/month. All tools are included: Huntress, SentinelOne, Fortinet, and Keeper. For manufacturing clients, the OT security assessment is included at onboarding. A typical 25-user fully managed engagement runs approximately $4,500/month. Manufacturing clients with OT scope are quoted after the boundary assessment because OT network complexity varies.
Can Fusion take over from our current IT or security provider?
Yes, and the transition is planned so nothing breaks. We start with an assessment of your current environment, document what is in place, and migrate monitoring and endpoint protection in parallel with your existing tooling. Huntress and SentinelOne deploy alongside whatever you are running today, so there is no coverage gap during the cutover. For Hamilton manufacturers, the OT/IT boundary review happens before we touch any production system. Most transitions complete in two to three weeks with no downtime.
How does the City of Hamilton ransomware incident apply to private businesses?
In February 2024 the City of Hamilton was hit by ransomware that crippled roughly 80% of its network. The City refused the ransom and, through mid-2025, reported about $18.3 million in response and recovery costs. Its cyber insurer denied roughly $5 million in claims because multi-factor authentication had not been fully rolled out, which the policy named as the root-cause condition for coverage (CBC News, June 2025). The lesson for private Hamilton businesses is direct: insurers now treat MFA, EDR, tested backups, and a documented incident-response plan as conditions of coverage, not best practices. Fusion enforces MFA and conditional access across Microsoft 365, deploys SentinelOne and Huntress, and documents tested business-continuity and disaster-recovery plans so your claim is not the one that gets denied.
Does Fusion support hybrid and remote teams in Hamilton?
Yes. Huntress MDR and SentinelOne XDR protect every endpoint regardless of location — office, home, or field site. Keeper enforces credential security and MFA across all cloud services. Conditional access policies flag unusual login behaviour from new locations. Our help desk is available 24/7 by phone, email, or chat. If your team works from the Hamilton office, Stoney Creek plant, or home, the coverage is identical.
What compliance frameworks does Fusion cover for Hamilton manufacturers seeking ISO 27001 or OEM certification?
Fusion builds every engagement on CIS Controls v8.1 and the NIST Cybersecurity Framework, both of which map directly to ISO 27001 Annex A controls. For manufacturers feeding OEM supply chains, we also apply IEC 62443 zone-and-conduit architecture to segment OT networks — the standard most automotive and industrial OEMs now require of their suppliers. Where defence or cross-border contracts come into play, we align to NIST 800-171 and CMMC, and we produce SOC 2 and PCI-DSS documentation when your client base demands it. The point is a documentation package that shortens your audit, not a binder that sits on a shelf.
What does a cybersecurity audit for a Hamilton business involve?
A Fusion audit runs in five phases: an asset and exposure inventory (including OT assets like PLCs and SCADA for manufacturers), a control-gap analysis against CIS Controls v8.1, ISO 27001, or NIST CSF, vulnerability prioritization weighted by your real environment, an insurance and compliance alignment step, and a 90-day remediation roadmap. A scan finds open ports; an audit tells you where your coverage actually ends, where your insurer thinks it ends, and the gap between the two. The deliverable is a prioritized action list, not a 400-page findings dump.
What is an MSSP and does Hamilton need one?
A managed security services provider (MSSP) runs the security layer of your business: 24/7 threat monitoring, endpoint detection and response, alert triage, incident response, and compliance documentation. A managed IT provider (MSP) keeps your systems running; an MSSP keeps them defended. For most Hamilton businesses the honest test is simple — if you have manufacturing OT, PHIPA-regulated healthcare data, or any information a ransomware crew would pay to decrypt, you need MSSP-level monitoring, not managed IT with antivirus bolted on. Fusion delivers MSSP coverage with CISSP-led strategy and Huntress 24/7 managed detection on every account.
How is a vulnerability assessment different from a cybersecurity audit in Hamilton?
A vulnerability assessment is technical and point-in-time: it scans your external perimeter and internal network for known weaknesses (missing patches, exposed services, weak configurations) and produces a risk-weighted list of what to fix. A cybersecurity audit is broader and process-oriented: it measures your whole control program against a standard such as CIS Controls v8.1, ISO 27001, or NIST CSF, and assesses governance, documentation, and insurance alignment. Hamilton businesses usually need both — the assessment tells you what is exposed today, the audit tells you whether your program will hold up under an insurer or enterprise-client review. Fusion includes quarterly vulnerability reassessments for managed clients so the picture stays current.
Industries We Serve in Hamilton
According to Invest in Hamilton (2026), the city’s economy still leans on advanced manufacturing and steel, anchors the Hamilton Health Sciences and St. Joseph’s healthcare networks, and hosts a fast-growing legal and construction trade base.

Cybersecurity audit Hamilton: what it covers and what it costs
A cybersecurity audit is different from a vulnerability scan. A scan finds open ports. An audit maps your controls against a standard (CIS v8.1, ISO 27001, or NIST CSF) and tells you where your coverage ends, where your insurer thinks it ends, and where the gap between those two points lives.
Phase 1: Asset & Exposure Inventory
We enumerate every device, service account, and external-facing system. For manufacturing clients, this includes OT assets (PLCs, HMIs, SCADA) that standard vulnerability scanners miss or cannot safely probe. You cannot audit what you have not found.
Phase 2: Control Gap Analysis
We measure your environment against CIS Controls v8.1 and, depending on your sector, ISO 27001 or NIST CSF. Each control is rated present, partial, or absent, with evidence. Hamilton manufacturers get an IEC 62443 overlay for the OT side; healthcare suppliers get a PHIPA safeguard mapping. The output is a clear picture of where your real coverage ends.
Phase 3: Vulnerability Prioritization
Raw CVE scores lie. A high-severity flaw on an isolated test box matters less than a moderate one on your email gateway. We weight every finding by its real exploit path in your environment — for manufacturers, by its OT breach-path risk; for healthcare, by PHIPA exposure — so remediation effort goes where it actually reduces risk.
Phase 4: Insurance & Compliance Alignment
Cyber insurance questionnaires from Chubb, Intact, and Aviva ask specifically about MFA coverage, EDR deployment breadth, backup testing, and incident response plan existence. We map your audit findings directly to carrier requirements. The City of Hamilton’s $5 million denial for missing MFA is the reason this step exists.
Phase 5: Remediation Roadmap
The audit deliverable is a prioritized remediation list, not a raw findings dump. Each item includes: severity, affected systems, recommended control, estimated remediation effort, and mapped framework reference. You walk away with a 90-day action plan, not a 400-page compliance report.
OT-Specific Audit for Manufacturers
For Hamilton manufacturers, the audit includes an IEC 62443-aligned OT/IT boundary review. We walk the production floor, identify uncontrolled conduits between IT and OT networks, and map each pathway to a control (or the absence of one). This portion of the audit is included in the onboarding engagement for manufacturing clients.
What a cybersecurity audit in Hamilton typically costs
Fusion runs audits on a fixed-fee basis, scoped to the size of your environment and whether OT systems are in play. You agree the price before we start, so there is no open-ended consulting meter. For most Hamilton businesses the audit is the first step in a managed engagement, and for manufacturing clients the IEC 62443 OT/IT boundary review is folded into onboarding rather than billed separately. Ask for a scoped quote and we will confirm the fee in writing.
Managed security services Hamilton: what MSSP coverage actually means
Managed security is the layer between “we have antivirus” and “we have a security operations centre.” For a Hamilton business with 10 to 150 staff and no full-time security team, an MSSP runs the monitoring, response, and compliance work you cannot staff internally. Here is exactly what that covers at Fusion, and what makes a local CISSP-led MSSP different from a national one routing your alerts through a faceless queue.
What “managed security” includes at Fusion
- 24/7 SOC monitoring via Huntress MDR with human analyst review
- SentinelOne XDR with AI-driven detection and automated ransomware rollback
- Fortinet UTM perimeter with IPS, DNS filtering, and web gateway
- Monthly vulnerability scans with CVE prioritization
- Quarterly phishing simulations with training for click-throughs
- 1-hour critical response SLA, 4-hour on-site from Hamilton office
- Incident response plan + compliance documentation
What separates Fusion from national MSSPs
- Hamilton office at 64 Hatt St, Dundas — on-site response is a real capability, not a dispatch from the 400 series
- CISSP-certified engagement lead on every account — not delegated to a junior analyst
- OT/IT security expertise for Hamilton manufacturers (IEC 62443) — national MSSPs do not offer this for SMB accounts
- PHIPA-specific documentation for healthcare suppliers — not adapted from US HIPAA templates
- Canadian data residency — no security logs crossing to U.S. infrastructure
Hamilton MSSP engagement models
SOC-Only
Your IT team manages endpoints and infrastructure. Fusion runs the SOC layer: threat monitoring, alert triage, incident escalation, and compliance documentation. Designed for businesses with an internal IT person who needs security backing they cannot build in-house.
Co-Managed Security
Fusion handles security tooling, monitoring, and compliance while your internal team handles day-to-day helpdesk. Shared responsibility matrix keeps both teams clear on who owns what. Popular with Hamilton professional services firms that have junior IT staff but no security expertise.
Fully Managed MSSP
Fusion owns everything from endpoint to perimeter to compliance documentation. No internal IT required. For Hamilton businesses that want a single accountable provider with CISSP leadership, 24/7 SOC, and on-site capability without building a security team.
“Hamilton businesses ask me whether they need an MSP or an MSSP. The honest answer is: if you have manufacturing OT, healthcare data, or any information a ransomware crew would pay you to decrypt, you need MSSP-level monitoring, not managed IT with antivirus bolted on. Those are not the same thing.” — Mike Pearlstein, CISSP, CEO, Fusion Computing
Vulnerability assessment Hamilton: methodology and deliverables
A vulnerability assessment shows you what an attacker would find before they find it. Fusion scans the way Hamilton businesses are actually attacked — from the outside in, then from the inside out, with manufacturing OT assets treated carefully so probing never disrupts production. Here is the methodology and what you receive at the end.
External Perimeter Scan
We scan everything facing the internet — firewalls, VPN gateways, mail servers, and any exposed web or remote-access service. The City of Hamilton attack entered through an external internet-facing server, which is precisely the surface this phase maps. We flag open ports, outdated services, and weak remote-access configurations before an attacker does.
Internal Network Scan
Most damage happens after the perimeter is breached, as an attacker moves laterally. We scan the internal network for unpatched hosts, weak credentials, and flat segments. For Hamilton manufacturers this is where we confirm whether the OT network is truly isolated from the business LAN — the “partially segmented” gap that lets a phishing email reach the production floor.
Configuration Review
A clean scan with a bad configuration is still a breach waiting to happen. We review Microsoft 365 tenant settings, MFA and conditional-access policies, DMARC/email authentication, backup configuration, and administrator privilege sprawl against CIS Controls v8.1 benchmarks. Misconfiguration, not a missing patch, is what most often opens the door.
Risk-Weighted Report
We filter and weight findings by your actual sector risk. A CVE-7.8 vulnerability on an isolated test server is lower priority than a CVE-5.0 on your email gateway. Hamilton healthcare organizations get PHIPA-specific risk weighting. Manufacturing clients get OT breach-path priority scoring. You receive a clear top-10 list, not 400 raw findings.
Penetration Testing Option
Where a client needs proof rather than a list, we add authorized penetration testing: a controlled attempt to exploit the weaknesses the scan found and chain them into a real attack path. Many Hamilton enterprise-supplier contracts and cyber-insurance renewals now ask for a recent pen-test result. We scope it to your environment and never touch live OT control systems without an agreed, safe method.
Quarterly Reassessment
The threat landscape does not stand still. Fusion’s managed security clients receive quarterly vulnerability reassessments included in their engagement. New CVEs, environment changes, and added assets are rescanned and reported. Annual point-in-time assessments miss the 11-month window between them.
