Security Patching
Closing known vulnerabilities in code, servers and dependencies, and cleaning up the credentials and access around an application, so a known weakness does not sit unaddressed while the business runs on top of it.
What Security Patching Covers
This is narrower than general maintenance: it deals specifically with vulnerabilities, exposed access and stale credentials, rather than bugs, features or performance.
Where Vulnerabilities Usually Hide
- Outdated libraries with a publicly known vulnerability
- Admin panels reachable from the open internet with no additional protection
- Passwords reused across services, or never changed since setup
- Accounts still active for employees or vendors who left months ago
- API keys committed into code where anyone with repository access can read them
How We Patch Without Disrupting the Business
Prioritise by Exposure, Not Alphabetically
A vulnerability reachable from the public internet is closed before one that needs internal access to exploit.
Test the Patch Before Applying It Live
A security fix that breaks a feature is still an outage; patches are checked against the application's actual behaviour first.
Patch in a Sequence You Can Follow
Changes are applied and communicated in an order your team can track, rather than as one disruptive batch.
Beyond Patching: Access and Credential Hygiene
A vulnerability is only one way in. The other is a credential that should have been revoked months ago. Alongside patching, we review who and what can access the application, and remove or rotate what no longer belongs there.
Frequently asked questions
How do you find out which vulnerabilities apply to our application?
By reviewing the specific versions of the framework, libraries and server software in use against known vulnerability records, rather than applying a generic checklist that may not match your stack.
What decides the cost of a security patching engagement?
How many vulnerable dependencies are found, how deeply custom code depends on their older behaviour, and how much access and credential cleanup is needed alongside the patching itself.
What decides how urgently a vulnerability needs fixing?
Whether it is reachable from the public internet, whether it exposes customer data, and whether an exploit for it is already public.
Does this include removing access for former employees or vendors?
Yes. Reviewing and revoking stale accounts and credentials is part of the work, since a forgotten login is as much a risk as an unpatched library.
Do you need admin access to our servers and accounts?
Yes, scoped to what patching and access cleanup require. We work within your existing accounts rather than moving anything to ones we control.
Who keeps the rotated credentials and keys?
You do. New credentials are issued and stored under your business's own accounts and password management, not ours.
Is this a one-time fix or ongoing?
It can be either. A one-time patching pass addresses what exists today; an ongoing arrangement checks for new vulnerabilities as they are disclosed.
