CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams already running Zeek for network telemetry and Elasticsearch for log aggregation should use zeek2es.py to close the integration gap without custom Python work. The tool handles Zeek's native JSON output directly into Elasticsearch bulk format, cutting weeks off a DIY pipeline and eliminating parsing errors that leak events. Skip this if your team lacks Elasticsearch infrastructure or hasn't yet committed to Zeek; the narrow integration scope means it solves one problem exceptionally well and nothing else.
Mid-market and enterprise teams managing hybrid IT/OT environments will find Anrita Cyber Defense strongest for alert triage and attack chain visualization; its machine learning correlation engine catches multi-stage attacks that raw log alerts miss. The MITRE ATT&CK and Cyber Kill Chain detection rules ship ready-to-tune, and cloud-native deployment means you skip the infrastructure overhead of on-prem SIEM. Skip this if your priority is response automation and playbook execution; Anrita prioritizes detection and investigation over orchestrated remediation workflows.
