The short version

  • Only WireGuard has a free tier, so it costs nothing to try first.
  • Each has a real cost: Entrust Identity as a Service the application integration catalogue is smaller than that of the dedicated identity vendors, so uncommon SaaS applications more often need custom SAML configuration rather than a template.; WireGuard manual key management required; WireGuard does not provide automated peer discovery or key distribution mechanisms
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Entrust Identity as a Service

  • The application integration catalogue is smaller than that of the dedicated identity vendors, so uncommon SaaS applications more often need custom SAML configuration rather than a template.
  • Developer experience for customer identity use cases is behind the specialists, and teams building consumer signup flows will find the APIs and documentation less complete.
  • Advanced capabilities including adaptive authentication and credential management sit above the published entry price, so the two dollar figure rarely reflects what a regulated buyer actually spends.
  • There are two overlapping products, Identity as a Service and Identity Enterprise, and choosing wrongly at the start means a migration later rather than a licence change.
  • Identity governance, access certification and privileged access are not covered, so an organisation with audit-driven access review requirements needs a second vendor alongside it.

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)

Answered from the vendors’ own pages

Entrust Identity as a Service: Is MFA included or extra?

Multi-factor authentication is included in the workforce bundles rather than sold separately, which is not true of every competitor. Adaptive risk-based authentication sits in higher tiers.

WireGuard: Is WireGuard free?

Yes, WireGuard is free and open-source software. The Linux kernel module is licensed under GPLv2; implementations for other platforms use MIT or Apache 2.0 licences. There are no licensing fees.

Source
Entrust Identity as a Service: Does it do identity governance?

No. Access certification, role mining and joiner-mover-leaver governance require a separate product such as SailPoint or Saviynt.

WireGuard: How does WireGuard differ from IPsec and OpenVPN?

WireGuard replaces complex negotiation protocols and state machines with simple public-key cryptography. Its code is roughly 100 times smaller than IPsec, making it faster to audit, deploy, and maintain. It uses modern cryptographic primitives rather than legacy algorithms.

Source
Entrust Identity as a Service: Why choose this over Okta or Entra ID?

Almost always because of PKI, smart cards or derived credentials. Without that requirement the mainstream platforms are the stronger general purpose choice.

WireGuard: Can I use WireGuard for a commercial VPN service?

Yes. Several commercial VPN services (Mullvad, IVPN, ProtonVPN) use WireGuard as their underlying protocol. You must implement peer management, key distribution, and endpoint selection on top of the WireGuard protocol.
