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.
CVSS turns a vulnerability's characteristics into a number from 0 to 10 and a severity label. Here is what the score actually measures, how the metrics combine, and why the number alone should never drive your patching.
The libraries you install are only the tip of the iceberg. Each one pulls in its own dependencies, which pull in more, forming a tree that can run hundreds of packages deep. Understanding that tree is the first step to securing it.
Defense in depth is a layered security strategy that assumes any single control will eventually fail, so it stacks independent safeguards to slow and stop attackers. Here's how the model works and how it maps to the software supply chain.
Malware is any software built to do harm, from stealing data to locking up your files. Here's a beginner-friendly tour of the main types and how it gets in.
The BSD licenses are a family of short, permissive licenses. This guide explains the 2-clause and 3-clause variants, what each permits, and what they mean for compliance.
The GNU General Public License is the best-known copyleft license. This guide explains what it permits, its source-disclosure obligations, GPLv2 vs GPLv3, and what it means for your project.
VEX is a machine-readable advisory that states whether a product is actually affected by a known vulnerability. Here's how its status values work and why it cuts SBOM-driven false positives.
Software Composition Analysis (SCA) identifies the open source and third-party components in your code, then flags their known vulnerabilities and license risks. Here's how SCA works and what separates modern tools from legacy scanners.
Attack surface reduction is the discipline of removing every input, interface, and privilege an attacker could reach that your system does not actually need. Here's how to inventory, shrink, and keep it small.
