Cisco Secure IPS

Cisco Secure IPS is an intrusion prevention system engineered to detect and block malicious network traffic, exploit attempts, and zero-day vulnerabilities in real time across enterprise perimeters and internal network segments. Powered by the open-source Snort 3 inspection engine, Cisco Secure IPS delivers high-throughput deep packet inspection, protocol anomaly detection, and signature-based heuristic analysis to identify and neutralize evasive adversary techniques as communications traverse the wire.

The platform can be deployed as dedicated hardware appliances, integrated software modules within Cisco Secure Firewall, or virtualized inspection nodes inside public and private cloud environments. Cisco Secure IPS leverages real-time global threat intelligence from Cisco Talos to update vulnerability rules and attack signatures automatically, ensuring defenses stay synchronized against evolving attack vectors. Key technical capabilities include stateful protocol decoding, sensitive data filtering, SSL/TLS decryption inspection, and automated vulnerability shielding through virtual patching, which protects unpatched servers and endpoints from active network exploitation.

Common enterprise use cases include perimeter network intrusion prevention, internal network segmentation monitoring, regulatory compliance enforcement (such as PCI DSS and HIPAA), and protecting legacy infrastructure against known vulnerabilities. By integrating with Cisco Security Cloud Control, Cisco XDR, and enterprise SIEM architectures, Cisco Secure IPS empowers security operations teams with granular alert telemetry, reduced false positives, and accelerated threat mitigation across enterprise networks.
