Yes. No Bulgarian law prohibits VPN use, and people rely on VPNs at work, at home and while travelling. As an EU member, Bulgaria applies the GDPR, so services operating there follow the same data protection rules as elsewhere in the Union.

Website blocking in Bulgaria is narrow and goes through official procedures. The National Revenue Agency publishes a list of unlicensed gambling sites that internet providers must block, and courts and regulators can order blocks on unauthorised investment and crypto services and on some illegal content. Some people try to get around such blocks with a VPN or proxy, but the rules do not change because of that, so it is worth being careful.

A VPN encrypts your traffic and shows sites its IP address instead of yours. It does not change your legal obligations or the terms of the services you sign in to. For a plain-language overview, see what a VPN is and how it works.
