Should I use OpenVPN?

Secure VPN solutions for business & remote access - openvpn.net

· 1 month ago

Buy it if you have IT staff to self-host a battle-tested, open-source VPN or need SOC 2/HIPAA compliance. Skip it if you're a small, non-technical team wanting simple remote access — mesh VPN rivals are far easier.

Best for

  • IT teams self-hosting remote access
  • Organizations needing SOC 2/HIPAA alignment
  • Users who want an open-source protocol they control
  • Network admins already running firewalls

Not for

  • Non-technical users wanting one-click consumer privacy VPN
  • Small teams with no sysadmin time — config is fiddly
  • Speed-sensitive users; Reddit callers call it slower than newer rivals
  • Teams wanting zero-maintenance zero-trust SaaS access

Gotchas - check before you buy

high

Client-side flaws mean every endpoint must be kept updated, not just the server

medium

Access Server is licensed per connected device — costs climb with headcount

medium

Default configs need manual hardening; expect to follow the security guide

low

Guess: two overlapping products (Access Server vs CloudConnexa) make plan comparison confusing

Pros and cons

Cons

  • Newer WireGuard-based rivals tout far easier setup
