Sequoia Capital SEA

“The online world is about to get a whole lot worse as the AI revolution gets channeled towards building malicious code. Every cyber security solution out there is only probabilistically successful in protecting internet users, which is not of much comfort if they get hacked and lose money. SquareX is the first solution we've seen that takes a 100% protection approach - where irrespective of how new and sophisticated the attack is, it has no chance to infect users. This is the future we think all internet users deserve.”
