SquareX

With SquareX, users don't have to worry about whether a file or website is "safe" or "malicious". Opening it with SquareX guarantees safety. SquareX achieves this by having the user's browser work with its cloud service. Files or websites are opened in disposable cloud environments, but they are integrated seamlessly into the user's browser, ensuring no change in workflow. The disposable cloud environments create watertight sandboxes, so even if the file or website contains malware or exploits, it can neither attack the user nor SquareX's infrastructure.

After the user has finished viewing the file or website, they can dispose of the environment with a single click, which destroys all session data, including the files, viewing history, and any changes made.

Unlike probabilistic detection software like antivirus, SquareX is building a suite of products that keep users safe deterministically, with no loss of productivity.
