How to detect Kernel
Kernel signs its requests, so you detect it by verifying the cryptographic signature on each request. A valid signature proves the request came from Kernel; a copied user agent without the signature does not.

Every signal Verisoul checks for Kernel
Kernel signs its requests, so we verify who it is cryptographically, then check the rest of the session.

Questions about Kernel
How do you detect Kernel?
Kernel signs its requests, so you detect it by verifying the cryptographic signature on each request. A valid signature proves the request came from Kernel; a copied user agent without the signature does not.
What is Kernel?
Kernel is Hosted browser automation from Kernel that signs its requests.
Does Kernel identify itself?
Yes. Kernel signs its requests cryptographically, which is the strongest way an agent can identify itself.
Can a bot pretend to be Kernel?
Not convincingly. A bot can copy Kernel's user agent, but without Kernel signing keys its requests fail verification and it is not labeled Kernel.
How common is Kernel?
Very uncommon. Rare, brand new, or not seen on Verisoul traffic yet.
What does the Verisoul API return for Kernel?
Every session Verisoul identifies as Kernel carries an agent block with id "kernel", name, provider, type "headless_automation", detection_method "signed" and the detection_signals used (cryptographic, device, behavioral). Build rules on the id, type and detection method.
