Arkose MatchKey Challenges

Challenge-response that stops bots and sabotages attackers' ROI

Every digital business – including yours – is vulnerable to account takeover, credential stuffing and other cybercrime. But traditional CAPTCHAs are ineffective against bots, and they frustrate legitimate users while hurting conversion rates. Arkose Labs' user-friendly challenges thwart advanced bot-driven attacks, improving the experience for your genuine customers while keeping cybercriminals at bay.

How Intelligent Challenge-Response Works

The Arkose Bot Manager platform analyzes traffic based on its risk profile, allowing the large majority of good users to proceed unchallenged. But when it encounters suspicious traffic, it presents challenges that gradually increase in difficulty, depending on the associated risk of the suspect session. Most good users do not see challenges, but those who do only have to solve a simple and fun puzzle that takes mere seconds.

Attackers, on the other hand, must invest significant time and effort to overcome challenges at scale. As costs rise, they abandon their attempts. This approach effectively bankrupts the business model of bots.

MatchKey Challenges

MatchKey challenges are an innovative security measure that provides a user-friendly and effective way to verify human presence. Unlike traditional CAPTCHAs, Arkose MatchKey presents users with a set of images or objects and requires users to select matching pairs within a given time frame. This state-of-the-art series of challenges with industry-leading security may produce more than 1,250 variations of a problem – effortlessly solved by legitimate users but incredibly tricky for automation.
