User-Agent claims Chrome 153.0.0.0 |
TLS extensions or signature algorithms differ from every measured Chrome capture
The cipher suites match Chrome, but the extension set or signature algorithms differ from every capture even after normalizing handshake-variant extensions. Most likely a field-trial, ECH, or build variant the catalog has not captured; occasionally mimicry. This sharpens as catalog coverage grows.

TLS cipher list matches no measured Chrome capture
The offered TLS cipher suites match no controlled capture of Chrome. Cipher lists are very stable per browser, so a different one is a real inconsistency — though a TLS-inspecting proxy re-originating the handshake is an honest cause, which holds this at medium.

TLS cipher list matches no measured PowerShell capture
The offered TLS cipher suites match no controlled capture of PowerShell. Cipher lists are very stable per browser, so a different one is a real inconsistency — though a TLS-inspecting proxy re-originating the handshake is an honest cause, which holds this at medium.

TLS cipher list matches no measured Chrome capture
The offered TLS cipher suites match no controlled capture of Chrome. Cipher lists are very stable per browser, so a different one is a real inconsistency — though a TLS-inspecting proxy re-originating the handshake is an honest cause, which holds this at medium.

TLS cipher list matches no measured Firefox capture
The offered TLS cipher suites match no controlled capture of Firefox. Cipher lists are very stable per browser, so a different one is a real inconsistency — though a TLS-inspecting proxy re-originating the handshake is an honest cause, which holds this at medium.

User-Agent claims Chrome 151.0.1355.231 |
TLS cipher list matches no measured Chrome capture
The offered TLS cipher suites match no controlled capture of Chrome. Cipher lists are very stable per browser, so a different one is a real inconsistency — though a TLS-inspecting proxy re-originating the handshake is an honest cause, which holds this at medium.

User-Agent claims Firefox 155.0 |
TLS extensions or signature algorithms differ from every measured Firefox capture
The cipher suites match Firefox, but the extension set or signature algorithms differ from every capture even after normalizing handshake-variant extensions. Most likely a field-trial, ECH, or build variant the catalog has not captured; occasionally mimicry. This sharpens as catalog coverage grows.
