Security: Proton VPN doesn't pull punches when it comes to privacy, either. It uses military-grade encryption to keep your data secure and unreadable to third parties, and its Secure Core servers give you an added layer of protection if you need it.

Update November 30: Proton VPN's flash sale has now expired. However, Proton VPN's Black Friday deal is still great value. It's 70% and $2.99 per month until at least Monday December 2.

Black Friday is here and the biggest shopping event of the year does not disappoint with VPN deals. Most VPN providers began offering killer discounts on subscription plans early and most deals are expected to run through the entirety of the holiday season.
