If you were to take two exceptionally paranoid pieces of software and lock them in a room together, OSSEC and Security Onion would spend most of their time agreeing on just how many threats are lurking in the digital shadows. Both are open-source, both are obsessed with logs and intrusion detection and both are quite good at shouting “Aha!” when something suspicious happens. They also enjoy integrating with other security tools, because even the most neurotic watchdogs appreciate a second opinion.
OSSEC, for its part, is the sort of software that frets over individual machines like an overprotective parent. It’s been doing this since 2004, back when most people thought firewalls were enough and it continues to do so across Linux, Windows and macOS. Originally conceived in Brazil, it now enjoys a global reputation for keeping system administrators awake at night with security alerts they didn’t know they needed.
Security Onion, on the other hand, doesn’t care so much about individual machines—it wants to watch the whole network, like a nosy neighbor with an expensive telescope. Since 2008, it has been the go-to toolkit for blue teams, forensic analysts and anyone who enjoys catching cybercriminals in the act. Born in the United States, it comes bundled with enough security tools to make even the most battle-hardened hacker reconsider their career choices.
