A cluster running on defaults works fine and is wide open. We lock it down without breaking what runs on it.
We roll changes out in stages so nothing that already runs stops.
This is the starting point in many companies that ship fast and are regulated.
Kubernetes comes up fast and works right away — which is why the day-one configuration often stays for years. Containers run with excessive permissions, traffic between them is unrestricted, and no one controls which image is allowed to run.
We define the scope after an assessment — starting with the element that lowers your risk fastest.
We lock down the cluster without breaking what runs on it.
We review the cluster configuration — permissions, namespace isolation, access to the management interface — and point out what is open only because it was open on day one. Instead of catching unsafe deployments by hand, we introduce policies that block them automatically. We limit traffic between services to what genuinely needs to communicate, so a compromised container does not open the way to the rest. Finally we turn on runtime detection — a signal when something happens in a container that was never there before.
Each stage leaves you with a concrete result, not meeting notes.

Implementation ends with working configuration and evidence, not a report full of recommendations. Here is an example.

Compromising one service does not open the way to everything else.
The signal arrives as it happens, not during a log review after the fact.
Illustration. We choose scope and tools after the assessment.
We define the scope after a call and an assessment. Smaller engagements close in a few weeks; larger ones we split into stages, so the result is visible after the first.
Usually not to all of it. In most cases access to the build pipeline configuration and organization settings is enough. We define the scope in writing before we start.
Yes, but not full time. We need contact with someone who knows the system, and a review of our changes. The rest is on us.
We plug into what already works for you. Replacing a tool is the most expensive and least often necessary way to improve security.
No. We work with standards and tools your team knows or will quickly learn — not a proprietary method only we understand. Everything is documented and handed over.
We wire controls so they run in the background. If one starts blocking work, we tune it or move it to a different point in the process.
