Security designed with you in mind

We’ve crafted a unique and powerful suite of enhanced security designed specifically to protect every aspect of your digital life — securing your personal data, your browsing, and your peace of mind.

Malware can’t hide from us

Your macOS might stop some malware variants, but it can’t help you if you’re already infected. Our antivirus for Mac not only blocks viruses, spyware, Trojans, and other malware in real-time, it also scans your entire Mac for already-hidden threats.
