Look beyond one webdriver flag
Automation can spoof one signal, so Voidek combines browser collect data with request headers, route pressure, and client classification.

Use decisions server-side
Server middleware calls the Voidek decision API before returning protected content, allowing allow, log, challenge, and block outcomes.
Keep false positives visible
Decision reasons and scores make it easier to tune policies before strict blocking reaches normal users.
FAQ
Questions teams ask before turning on crawler defense.
Can headless browsers bypass detection?
Some can spoof signals. Voidek raises the cost by combining multiple signals and route-level behavior instead of depending on a single flag.
Does this require a browser snippet?
The snippet improves browser verification, while server middleware can still classify many clients from headers and request behavior.
