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.
Symmetric encryption uses one shared key for both locking and unlocking. Asymmetric encryption uses a key pair, one public and one private. One is fast; the other solves the key-sharing problem.
A security patch is a small update that fixes a specific flaw in software. Here is what patches are, why applying them quickly matters, and how teams manage them.
An artifact attestation is a signed, machine-readable claim about a software artifact, bound to it by digest. Here's how the in-toto structure works and what kinds of claims it carries.
A Secure SDLC embeds security activities into every phase of software development — from planning to production — instead of bolting a security review on at the end. Here's what each phase looks like and how to build one.
The GNU Affero GPL closes the SaaS loophole: it extends copyleft to software used over a network. Here is what AGPLv3 requires, why companies treat it cautiously, and what it means for you.
OSV is an open, ecosystem-native vulnerability database that expresses affected versions in precise, machine-matchable ranges. Here is how it works and why scanners rely on it.
Encryption scrambles data so it can be unscrambled later with a key. Hashing turns data into a fixed fingerprint that can never be reversed. One protects secrets; the other verifies them.
A software bill of materials is only useful if tools can read it. Two standards dominate — SPDX and CycloneDX — and knowing what each captures, how they differ, and when to use which is the difference between an inventory that works and one that gathers dust.
A software dependency is outside code your program relies on to run. Here is what dependencies are, why modern apps have so many, and why they matter for security.
