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.
Container security has matured significantly, but runtime protection remains a weak spot. Here's a practical guide to what works.
A practical look at Cilium Tetragon for Kubernetes runtime security, what eBPF gives you that audit logs do not, and where Tetragon fits in a real stack.
Static analysis catches known vulnerabilities. Runtime detection catches exploitation. Here is how to implement runtime threat detection for containerized workloads.
Field notes on running Tetragon, Falco, and Cilium eBPF controls in production Kubernetes clusters, with observed overhead, policy traps, and kernel constraints.
containerd runs most of Kubernetes today. Its defaults are reasonable, but reasonable is not hardened. Here is how to close the gaps.
gVisor intercepts syscalls in userspace and implements a minimal kernel in Go. It is a genuinely different approach, with genuinely different trade-offs.
Container escapes remain a real threat in multi-tenant environments. A look at the latest techniques, CVEs, and defenses as container security matures in 2023.
Build-time SBOMs capture what goes into your software; runtime SBOMs capture what actually runs. Understanding the difference is critical for accurate vulnerability management.
