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.
An open source project can show an intake channel, a triage record and published advisories. Learn the evidence a maintainer can produce alone.
An open proxy forwards traffic for anyone. Attackers use it to hide their origin and reach internal hosts. Learn how to find and close yours.
Securing Node.js mostly means securing what runs in it: dependencies, input, HTTP timeouts and process permissions. A checklist from the Node.js docs.
An open redirect sends users to any URL an attacker supplies. In Node.js, redirect only to allowlisted targets and never pass raw input to res.redirect.
Network traffic can be captured as packets, summarized as flow records or read from logs. What each shows, what encryption hides, and a collection plan.
Network segmentation splits a network into zones with rules between them so one breach cannot reach everything. Learn how to choose zones and roll out.
Network DLP inspects data in motion for sensitive content and policy matches. Learn how it works, why TLS limits it, and which controls to pair with it.
Network ACLs allow or deny traffic by numbered rules at the subnet edge. Learn rule order, why stateless matters and how they differ from security groups.
NAC decides which devices and users may join a network using credentials and health checks. How 802.1X and RADIUS work, where it fails, and a rollout plan.
