ExpressVPN Clears 2 New Privacy and Cybersecurity Audits

The virtual private network gets picked apart by Cure53 and KPMG -- but comes away with high marks.

"Security is at the core of everything we do. We as a company are wholly devoted to the security and privacy of not only our customers but also our employees."

Aaron's top picks

Private DNS

ExpressVPN protects your internet traffic and your DNS queries by running its own encrypted DNS on every VPN server.

Network Lock

Network Lock is the ExpressVPN kill switch. It keeps your data safe even if your VPN connection drops, blocking all internet traffic until protection is restored.

Ad blocker

Our ad blocker filters out most display ads and stops them from loading and appearing on your browser. Included with every ExpressVPN subscription.
