Kubernetes Network Policy Best Practices for a Zero-Trust Cluster
The core Kubernetes network policy best practice is to default-deny all traffic and then explicitly allow only what each workload needs. Here is how to build that model without breaking your cluster.
Default-deny NetworkPolicy: closing the pod-to-pod gap in Kubernetes
Kubernetes pods allow all traffic by default, and many clusters' NetworkPolicy YAML silently does nothing because the CNI plugin never enforces it.
Unified identity, segmentation, and policy-as-code for multi-cloud
38% of breaches start with stolen credentials, per Verizon's 2024 DBIR — the fix for multi-cloud estates is unified identity, segmentation, and policy-as-code, not per-provider IAM.
Best zero trust architecture implementation tools
A vendor-neutral buyer's guide to zero trust architecture tools: what to evaluate, plus honest strengths and limits of six leading platforms compared.
Service Mesh Security: mTLS, Authorization, and Zero Trust
A service mesh can give you mutual TLS between every service, identity-based authorization, and encrypted traffic without touching application code — or it can become an over-privileged proxy layer you never locked down. Here is how to do it right.
The four pillars every enterprise security program needs
Identity, patching, segmentation, and logging aren't a checklist — they're the four controls that determine whether a breach stays contained or becomes Log4Shell.
Implementing mTLS in Kubernetes clusters: a hands-on guide
Kubernetes ships zero built-in encryption for pod-to-pod traffic — here's how cert-manager and service meshes fix that, and the five misconfigurations that quietly undo it.
Zero Trust Architecture, Explained
Zero trust replaces the trusted internal network with a model that verifies every request explicitly, regardless of where it comes from. Here's what it actually means and how to move toward it.
What Is Defense in Depth in Security?
Defense in depth is a layered security strategy that assumes any single control will eventually fail, so it stacks independent safeguards to slow and stop attackers. Here's how the model works and how it maps to the software supply chain.
Kubernetes Network Policies: A Practical Guide
By default every pod in a Kubernetes cluster can talk to every other pod. NetworkPolicies are how you replace that flat network with least-privilege segmentation — here is how to design and roll them out without breaking traffic.
Kubernetes network policies for zero trust
Kubernetes network policies default to allow-all. Here is how default-deny rules, CNI enforcement, and policy testing build real zero-trust segmentation.
Federal AST mandate M-22-09 explained
OMB's M-22-09 forces federal agencies to run continuous application security testing under zero trust. Here's what changed, and how Safeguard compares to Checkmarx.
