Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Tenable

  • Pricing starts at $3500/year for Tenable One VM, expensive for small organizations
  • Many enterprise features require custom quote and sales engagement
  • Cloud Exposure, OT Exposure, and other modules have no published pricing
  • Multi-year contracts common, limiting flexibility
  • Setup and configuration complexity for enterprise deployments

WireGuard

  • Manual key management required; WireGuard does not provide automated peer discovery or key distribution mechanisms
  • No built-in support for address allocation or DHCP; all IP assignments must be manually configured
  • Limited to UDP; TCP encapsulation requires wrapper tools, making it unsuitable for environments blocking UDP
  • Stateless protocol design means lost packets trigger peer disconnection rather than transparent reconnection
  • Requires operational expertise to securely configure and deploy; not suitable for non-technical users without wrapper tools (Tailscale, Mullvad)
