When selenium client webdriver is detected running the Chrome browser it is not being blocked due to low score being assigned by PBD (Suspicious Browsers) mechanism.


A bot which running selenium Chrome webdriver isn't mitigated by DoSL7 PBD mechanism.


This occurs when ASM is provisioned with proactive bot defense enabled.



Fix Information

Only for Desktop Google Chrome browsers, the PBD javascript code checks if a plugin called "Widevine Content Decryption Module" doesn't exists, the browser considered as running via the selenium tool and will be blocked by PBD.
