CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
ISPs and hosting providers managing abuse at scale need Abusix Guardian Ops to collapse MTTR from weeks to days through automated case routing and takedown workflows that eliminate manual handoffs between abuse, legal, and network teams. The platform covers NIST RS.MA, RS.AN, and RS.CO, meaning it handles the full incident lifecycle from detection through coordinated external reporting, which regulatory auditors actually care about. Skip this if you're a mid-market enterprise without significant abuse reporting obligations; Guardian Ops is built for vendors processing hundreds of cases monthly, not internal security operations.
Security teams already running Zeek will find BZAR's value in its ATT&CK-aligned detection logic without the licensing cost of commercial NDR platforms. The 622 GitHub stars and free deployment model mean you're getting detection tuning from practitioners who've actually hunted in Zeek logs. BZAR prioritizes detection over response; you'll need a separate workflow to act on the notices it raises, so it's a poor fit for teams expecting their NDR tool to handle investigation and containment.
