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.
Deno is secure by default, but its permission model only protects you if you use it deliberately. Here is how to run Deno with least privilege and keep its dependency graph clean.
Express is the default web framework for Node.js — and a small, deep dependency tree that has produced open-redirect, XSS, and ReDoS CVEs. Here is how to run Express safely in 2026.
FastAPI's type system catches a whole class of bugs for free, but async I/O, JWT handling, and dependency injection introduce risks that Pydantic will not save you from.
os/exec keeps the shell out of your way — but user-controlled binaries, flag injection, and PATH tricks still get Go services popped. Here's the prevention playbook, not just the theory.
Native Java deserialization can turn a single readObject() call into remote code execution. Here's how gadget chains work and how to shut them down.
The recurring JavaScript security mistakes that show up in real breaches — unsafe deserialization, injection sinks, prototype pollution, and trusting client input — each with vulnerable and fixed code.
Null safety is a reliability win, not a security boundary. A Kotlin app inherits every JVM supply-chain CVE and the full Android attack surface — here's what the type system doesn't do for you.
OWASP Dependency-Check is the classic way to scan Java and Maven projects against the NVD. Learn to run it, tame its false positives, and move beyond CPE matching.
NumPy is the numerical foundation of the Python data ecosystem — and while many of its CVEs are disputed, the pickle-based numpy.load deserialization risk is real and worth understanding.
