Features, pricing, ratings, and pros & cons — compared head-to-head.
6Guard (IPv6 attack detector) is a free intrusion detection and prevention systems tool. ExtraHop IDS is a commercial intrusion detection and prevention systems tool by ExtraHop. Compare features, ratings, integrations, and community reviews side by side to find the best intrusion detection and prevention systems fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams defending dual-stack networks or lab environments will find 6Guard valuable for IPv6-specific intrusion detection, a gap most mainstream IDS platforms still leave uncovered. Backed by The Honeynet Project and built during Google Summer of Code 2012, it brings credibility to a niche that typically gets ignored until an IPv6 attack actually lands. Skip this if you need production-grade threat hunting across IPv4 and IPv6 simultaneously; at 43 GitHub stars and no commercial support, 6Guard works best as a specialized sensor for organizations that have already decided IPv6 monitoring is a separate line item.
Mid-market and enterprise teams managing hybrid or cloud infrastructure need RevealX NDR's IDS when encrypted traffic is your detection blindspot; the built-in decryption capability means you're actually seeing threats in TLS sessions while competitors are flying blind. The continuous PCAP repository and forensic lookback give you 90 days of evidence for incident analysis without the storage footprint of traditional tap-and-store approaches. Skip this if your network is mostly north-south perimeter traffic and you already have solid east-west visibility from your existing tools; RevealX shines when lateral movement and encrypted command channels are your actual threat model.
