 Slips is a powerful endpoint behavioral intrusion prevention and detection system that uses machine learning to detect malicious behaviors in network traffic. Slips can work with network traffic in real-time, PCAP files, and network flows from popular tools like Suricata, Zeek/Bro, and Argus. Slips threat detection is based on a combination of machine learning models trained to detect malicious behaviors, 40+ threat intelligence feeds, and expert heuristics. Slips gathers evidence of malicious behavior and uses extensively trained thresholds to trigger alerts when enough evidence is accumulated.
