Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise security teams managing hybrid workforces across multiple networks will find Absolute Insights for Network essential for visibility into device behavior where traditional perimeter controls fail. The tamper-proof Windows client and cross-platform coverage (Windows, macOS, iOS, Android) catches data exfiltration and man-in-the-middle attacks that flow-based NDR misses, with explicit support for ZTNA policy enforcement visibility. Skip this if your priority is incident response automation; Absolute excels at continuous monitoring and threat detection but leaves response workflows to your existing playbooks.
Network security teams with limited budgets who need visibility into encrypted traffic and lateral movement will get the most from Corelight Zeek; its passive monitoring generates 70+ log types from network packets alone, catching threats that endpoint tools miss. The 3,000+ event types tracked and 270+ community packages mean you're not building detection logic from scratch. Skip this if your team lacks the expertise to tune Zeek output or integrate raw network logs into your existing SIEM; Zeek demands engineering effort upfront and won't hand you pre-built dashboards.
