Private Internet Access

  • Monthly plan is priced noticeably higher than the discounted multi-year commitments, penalizing short-term users.

  • Headquartered in a jurisdiction whose privacy reputation some competitors market against, despite audited no-logs claims.
  • App interface is less streamlined than some higher-priced premium VPN competitors.
