Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
Kubernetes Secrets are base64-encoded, not encrypted. That is the start of the problem. Here is a no-nonsense comparison of the tools that actually solve secrets management in Kubernetes.
By default, every pod can talk to every other pod. Network policies change that, but most implementations are incomplete. Here is how to build real microsegmentation in Kubernetes.
Ingress controllers are the front door to your Kubernetes cluster. Misconfigurations here expose everything behind them.
Calico is the most widely deployed Kubernetes network plugin. Its policy model is powerful but has gotchas that trip up even experienced teams.
Service meshes promise automatic mTLS. The reality involves permissive modes, certificate management complexity, and gaps that attackers can exploit.
Cilium uses eBPF to provide network security that standard Kubernetes NetworkPolicies cannot match. Here is what it adds and how to configure it.
PodSecurityPolicy is dead. Pod Security Standards replaced it. Here is what changed, what the three levels mean, and how to migrate without breaking your clusters.
Gatekeeper brings OPA's policy engine to Kubernetes. The learning curve is steep but the flexibility is unmatched. Here is how to write, test, and deploy Rego policies that enforce real security.
Scanning for vulnerabilities means nothing if you cannot enforce the results. Supply chain policy engines in Kubernetes turn security findings into hard deployment gates.
