Network Detection
TLS Anomaly
Detect browser spoofing via TLS fingerprint analysis
What it detects
Compares the visitor's TLS fingerprint (cipher suites, extensions, supported protocols) against expected fingerprints for their claimed browser. Mismatches indicate browser spoofing, headless browsers, or automated tools.
How it works
Captures the TLS ClientHello during the handshake and generates a JA3/JA4 fingerprint. Compares this against a database of known browser TLS fingerprints. Flags discrepancies between the User-Agent string and the actual TLS capabilities.
