Imperva Avis 

The website repeatedly blocks phone from website access making driving test access impossible.

Complete dogshit. More false positives than if they flipped a coin to decide whether to block access to a site.

I havent encountered worse protecting service in my life, vibe coded garbage which propably never seen bot behavior in its existence

Absolute joke of a service. Couldn't recognise real traffic if it slapped them around the face.

Worst of all verification services. Incredibly lazy. This is used by Pokemon Center to combat botting but it just bans anyone who does something as simple as refreshing the page. Next level lazy and overall ruins the online shopping experience for an incredibly large number of Pokemon fans

blocked me after waiting in a queue for 3 hours. horrible

Highly unreliable and prone to errors in distinguishing between human and non‑human objects.

Purely trash system on distinguish a real human action vs bot

Absolutely baffling what sort of tech this company is running. The system blocks you for no valid reason, especially if you click a bit too frequently. It feels like you’re being punished for actually using the site. The CAPTCHA process is just as ridiculous — you practically have to select a wrong answer first and then correct it just to “prove” you’re human. Even after jumping through all the hoops, they randomly block your IP with no explanation. Meanwhile, actual bots seem to roam freely without any issue. Instead of stopping malicious traffic, they’re just frustrating genuine users. Anyone considering them for their tech needs should seriously rethink their options.

Imperva can kiss my digital foot, stop blocking my access from sites you scrutinizing pieces of NON COMPUTABLE JUNK

Just blocks human beings for trying to buy products.
Absolutely terrible at tracking actual bots

Can't block bots for shit, blocks people really well though. Completely useless.

I'm just trying book a driving test. Why are you blocking me!!

So frustrating, so useless

It’s stressful enough trying to book a practical driving test on the DVSA website when they’re so scarce, but it’s made doubly frustrating when you’re constantly mistaken as a bot! In my opinion this is not fit for purpose.

Pathetically bad how did you wiggle your way into "protecting" the DVSA website, gets stuck on loading after completing Captcha.

don't use this company if you want customers. It blocked my access to a webpage because I tried clicking on the login and buying option too fast, and now that page lost me as a client

Company is trash. They give you a captcha. You select all the correct things. It errors out and gives you a captcha again. You do this three times and then they give you an Error 15. That or if you succeed in the captcha and enter a queue, they kick you back to the captcha a minute later, resetting your queue.

Lächerlich, ich werde von der Seite gesperrt, ohne jeglichen Grund. Wahrscheinlich denkt es, ich bin ein Bot. So kann man auch Kunden verlieren...

Same as the rest of the 1 star reviews. This company is awful, unfit to be in business, after last weeks nightmare on Pokemoncenter.com and consistent lack of updates/upgrades to the system.

Got detected as a bot, the WORSE CAPTCHA i ever seen or heard of in my whole life.
