NetWitness Platform vs VbtEngine UEBA

NetWitness Platform is a threat detection, investigation, and response platform for complex IT and OT environments. Its modules include network detection and response, endpoint detection and response, SIEM, SOAR, and UEBA, with additional OT security coverage described. NDR uses full packet capture and metadata analysis to monitor infrastructure and reconstruct sessions. Machine learning and behavioral analytics are described for identifying known and unknown threats and anomalous behavior, with real-time alerting. SIEM ingests logs from over 350 sources, including AWS, Azure, Office 365, and Salesforce, through Syslog, ODBC, SFTP, FTPS, and SNMP. It provides reporting templates and use cases for SOX, PCI, HIPAA, and NERC. SIEM can run on-premises, virtually, or in the cloud, including AWS and Azure. The EDR agent is described for hundreds to 100,000 endpoints with near-zero end-user impact. NetWitness is paid, supports Linux, self-hosted, and web deployments, and lists pricing on request.

VbtEngine UEBA analyzes user and entity behavior to surface anomalies and insider-threat signals, then assigns risk scores to findings. It uses existing FortiGate VPN and SSH logs from fw_vpn_log and fw_ssh_log, with no new agent required. The engine builds a 30-day behavioral baseline while excluding the latest 24 hours, and describes twelve anomaly types, including new users or source IPs, unusual hours, volume spikes, suspected account takeover, lateral movement, and suspected brute force. Related signals can be correlated so that two individually medium-risk signals may become a high-risk finding. Location filtering excludes internal, VPN, loopback, link-local, multicast, and CGNAT addresses; two IPs in the same /24 are not treated as different locations. Heavy scans run in a background worker while the main API reads a cache. Data, deduplication, and seven-day anomaly history are kept separate by tenant. Sequence correlation can automatically open a SIEM case after a brute-force lockout followed within an hour by specified anomalies. The technical summary specifies on-prem deployment.
