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.
The .NET SDK ships a built-in vulnerability scanner: dotnet list package --vulnerable. Here is how to audit NuGet dependencies with it — and where to go beyond it.
How NuGet supply chain attacks work, from dependency confusion to typosquatting, and the concrete controls, lock files, source mapping, and signing, that lock down your .NET build.
Vulnerable and Outdated Components rank #6 in the OWASP Top 10 (2021). A deep dive into transitive risk, real CVEs like Log4Shell, and how to fix it in 2026.
Pillow is the default image library for Python — and because it parses untrusted image bytes and once shipped an eval-based ImageMath, it has a long, real CVE history spanning arbitrary code execution and native buffer overflows.
Prototype pollution turns a single crafted JSON key into process-wide corruption — and it has escalated to RCE in real Node.js apps. Here is how the attack works and four layers of defense that stop it.
Every time Python code shells out with user input, an attacker gets a vote on what the shell runs. The fix is almost always to stop using the shell at all.
The Go module system ships with a tamper-evident checksum log and a public proxy most teams never configure deliberately. Here's how to turn those defaults into a real supply-chain control plane.
cargo-audit checks your Cargo.lock against the RustSec Advisory Database, flagging vulnerable, yanked, and unmaintained crates. Here is how to use it and extend it.
How SQL injection still happens in Entity Framework Core apps, which EF Core APIs are safe by default, which ones aren't, and the exact patterns that keep raw SQL parameterized.
