Key security risks unique to WebAssembly runtimes and mod...
WebAssembly runs your edge functions, service mesh plugins, and smart contracts. Here are the WebAssembly security risks hiding behind the sandbox.
Analysis of documented WebAssembly sandbox escape vulnera...
Real documented WASM sandbox escape cases in Wasmtime and Wasmer, covering affected versions, severity, disclosure timelines, and how to remediate.
Node.js runtime CVE roundup
A roundup of Node.js runtime CVEs since 2024 — command injection, HTTP smuggling, permission bypasses, and why runtime flaws evade typical dependency scanners.
Best IAST tools for runtime application security testing
A practical, no-fluff comparison of IAST tools for runtime application security testing — evaluation criteria, honest vendor tradeoffs, and where supply chain risk still slips through.
Best cloud workload protection platforms (CWPP)
An honest, no-hype comparison of leading cloud workload protection platforms — evaluation criteria, real vendor tradeoffs, and where supply chain security fits in.
Falco vs. Tetragon vs. Tracee: choosing a Kubernetes runtime security tool
Falco graduated CNCF in February 2024, Tetragon enforces in-kernel, and Tracee ships 330+ prebuilt eBPF detections — here's when each one actually wins.
Reverse shell attack mechanics and detection
Reverse shells flip the direction of the connection so outbound firewall rules never fire — here is how they work and the signals that catch them anyway.
Container Runtime Security Monitoring: Catching the Breach in Progress
Scanning tells you what could go wrong before deploy. Runtime monitoring tells you what is going wrong right now. Here is how to detect container attacks as they happen.
eBPF Runtime Security for Kubernetes
eBPF lets you observe and enforce security at the kernel level — every syscall, network connection, and process exec — without kernel modules or instrumenting your apps. Here is how tools like Falco, Tetragon, and Cilium use it to catch what image scanning cannot.
The security case for Node.js's newer runtime features
Node's permission model went stable in v23.5.0, the built-in test runner in v20 — both quietly shrink attack surface, but neither is the sandbox teams assume it is.
Governing AI agents inside the execution loop
Snyk's Evo Agentic Development Security, in open preview since June 23, 2026, hooks directly into an agent's tool calls — proof that pre-deployment review can't govern a decision made mid-session.
Container Escape Vulnerabilities: How They Work and How to Stop Them
A container is a process with boundaries, not a virtual machine. When those boundaries fail, an attacker lands on the host. Here is the anatomy of real container escapes — runc, Leaky Vessels, Dirty Pipe — and how to defend against them.
