Vulnerability Management
Vulnerability management is not a scan. A scan produces a long list; management is the discipline of deciding what on that list genuinely matters here, fixing it, and confirming the fix held.
We run it as a continuous cycle across devices, servers, network equipment and cloud services, with reporting that shows exposure trending down rather than a document that grows longer each quarter.
The problem
Why long vulnerability lists never get shorter
Two things usually go wrong. The first is coverage: Windows updates are automated, so everyone assumes patching is handled, while the actual exposure sits in browsers, PDF readers, Java runtimes, the firewall's firmware, the switch nobody has logged into since installation, and an application server running an operating system that stopped receiving updates.
The second is prioritisation. A report listing hundreds of findings with no local context is unusable. A theoretical flaw in an internal tool matters far less than an internet-facing appliance two versions behind, but a raw severity score treats them similarly.
The fix is a cycle with an owner: discover everything, rank by real exposure, remediate on a schedule, verify, and record the small number of items that cannot be resolved yet along with what compensates for them.
What we do
The remediation cycle
- 01
Know what exists
Automated discovery of devices, servers, network hardware, virtual machines and cloud tenants, because unmanaged assets are where unpatched software survives.
- 02
Scan the whole surface
Operating systems, third-party applications, firmware on firewalls and switches, and configuration weaknesses in Microsoft 365 and cloud platforms — not just Windows updates.
- 03
Rank by exposure, not score alone
Internet-facing systems, anything holding client or financial data, and flaws that are actively being exploited are treated first, regardless of how the raw severity reads.
- 04
Remediate on a maintained cadence
Routine patching in defined windows, expedited handling for critical internet-facing issues, and coordination with vendors where a line-of-business application dictates the version.
- 05
Verify, then close
Re-scanning to confirm each fix applied and nothing regressed, so 'patched' means demonstrated rather than assumed.
- 06
Register what cannot be fixed
Items blocked by a vendor or an aging system are documented with a named owner, a compensating control such as segmentation, and a replacement date — visible in the technology roadmap.
Local context
Aging infrastructure is the common thread
Across St. Catharines professional services firms, manufacturers and non-profits, the same pattern appears: one essential system that dictates an old operating system, a firewall installed years ago and never revisited, and a server that everybody is nervous about touching.
These are budget and planning problems as much as technical ones. We surface them as costed roadmap items with a clear statement of the risk being carried, so leadership can make a decision rather than inherit one.
- End-of-life inventory
- Vendor version dependencies
- Costed replacement plan
- Interim containment measures
- Firmware maintenance schedule
- Risk register entries

Questions
Frequently asked questions
- How often should scanning run?
- Continuously for endpoints and servers through agents, with a monthly review cycle. Internet-facing systems warrant closer attention, since exploitation of a newly published appliance flaw often begins within days.
- Is this the same as penetration testing?
- No. Vulnerability management is the ongoing cycle of finding and fixing known weaknesses. Penetration testing is a point-in-time exercise where a tester attempts to chain weaknesses together. They are complementary, and testing is far more useful once the cycle is running.
- Can you patch software you did not install?
- Generally yes, for common third-party applications through our management platform. For specialised or vendor-locked software we coordinate the update with the vendor and track it to completion.
