✔ Frequently Asked Questions
Is SELKS legal?
Yes — SELKS is free and open‑source. It’s legal to use worldwide.
SELKS vs Security Onion?
SELKS = Suricata + Elastic focused IDS/IPS/NSM. Security Onion = full SOC platform (Suricata + Zeek + Elastic + PCAP + cases). SELKS is lighter; Security Onion is more comprehensive.
Can SELKS be used in production?
Yes — many use SELKS in production, especially smaller environments and labs. For larger enterprises, Stamus commercial solutions or Security Onion may be preferred.
