What We Do
We stop bot attacks. Today’s sophisticated bots impersonate human behavior to evade detection technologies. To defeat today's bots, we use a unique multilayered approach that enables us to verify the humanity of digital interactions with unmatched speed and accuracy across Applications, Performance Marketing, and Advertising use cases.
Why Work With Us
Fighting cybercrime is not easy. We’re constantly pitted against well-funded and highly-skilled hackers and botnets. In order for us to stay ahead of our adversaries, we solve problems unconventionally, move fast, and create ‘tau’ for each other to stop them. If our mission to keep the internet human appeals to you, we should talk.
