Protect your website from the harmful effects of bots

Bots represent more than 40% of global website traffic and are responsible for the majority of cyberattacks. Bot attacks regularly cause data breaches, service outages and orchestrate account takeovers.

It is incredibly easy to spin up a bot farm that will use thousands of VMs to scan for critical information, perform XSS attacks and inject crypto-mining scripts, posing an existential risk to small and established websites alike.

How bots impact your site:


Malicious actors can easily buy login credentials and credit card numbers on the dark web, and test them on unsuspecting websites using bot farms. Identify automated attackers and lock them out before they can hijack customer accounts or make fraudulent purchases.


2021 was the worst year on record for infrastructure outages caused by ransomware attacks. Beyond the headlines, cyberattackers are not only targeting public-facing websites, but internal portals and dashboards in order to hold businesses hostage. These cyberattacks require careful planning and execution, which you can predict by using bot monitoring on every web application that your company is using.

Fake Reviews

Positive online reviews are worth their word count in gold. Stop businesses from generating fake reviews using bot networks, and protect the reputation of your online marketplace.


Whether it's vacation rentals listings or airline prices, content scraping is a headache that's impossible to solve by conventional blocking techniques. You need real-time bot protection for content scrambling and data poisoning to stay ahead of the scrape.
