The PQC Network Scanner is a specialized tool designed for organizations transitioning to post-quantum security. Unlike traditional TLS scanners, which focus on certificate validity and classical cryptographic strength, this scanner assesses cryptographic exposure with a quantum perspective. It evaluates endpoints by inspecting RSA and elliptic-curve keys, along with identifying post-quantum algorithms and hybrid deployments. This functionality is crucial for organizations concerned about threats from adversaries who might harvest data now and decrypt it later. At its core, the scanner conducts a thorough inspection of TLS endpoints within an internal network. It retrieves full certificate chains, analyzes key types and sizes, and detects PQC-related object identifiers (OIDs). The tool can identify hybrid key-exchange mechanisms, such as X25519 combined with Kyber, and reviews TLS protocol versions and cipher suites to check for Perfect Forward Secrecy (PFS). This comprehensive evaluation provides insights into both classical and quantum-era cryptographic resilience. In addition to cryptographic assessment, the scanner offers intelligent device identification by correlating certificate metadata with DNS information and naming conventions. This allows it to classify various endpoints like routers, firewalls, and web servers, helping security teams pinpoint where specific cryptographic measures are deployed. The output report is detailed, assessing each endpoint for quantum vulnerability, PQC readiness, and TLS posture. It highlights configurations at risk and provides guidance for migration aligned with new standards, such as ML-DSA and ML-KEM. Version 2.0 of the scanner is tailored for enterprise networks, particularly in environments where intrusion detection or prevention systems (IDS/IPS) may complicate operations. It slows and randomizes scan traffic to prevent triggering these systems, applying pacing to both port checks and TLS handshakes. This approach is recommended for production or monitored networks to ensure smooth operation without raising alarms.
