Security updating and patching is the routine work of keeping frameworks, libraries, plugins, and server software current. It is unglamorous and it is what prevents the majority of incidents from ever happening.
Let's TalkThe majority of breaches use a flaw that was already known and already fixed upstream.
Unsupported components are the ones that tend to appear in an incident report afterwards.
Applied regularly they are routine; left alone they become a risky project nobody wants to own.
It happens on a schedule rather than whenever someone finds the time.
This is one part of our maintenance and support work. Engagements rarely stay in one box: a platform rollout turns into something custom, and both then need looking after. That is why our software development and implementation practice treats implementation, custom development, and ongoing support as one continuous piece of work rather than three separate vendors.
