The short version

  • Only Authelia has a free tier, so it costs nothing to try first.
  • Each has a real cost: Authelia depends on a reverse proxy: it is not a standalone identity provider; Trend Micro Vision One licensing is a credit pool consumed at different rates by different modules, so forecasting a renewal means modelling which capabilities you will activate rather than counting users, and switching on a new module silently draws down the budget for an existing one.
  • They diverge on capability: Authelia covers Reverse proxy integration, Trend Micro Vision One covers Cross-layer correlation.
  • Prices and features above were last checked on 30 August 2026.

Trend Micro Vision One

  • Regulated organisations needing a specific hosting region for detection telemetry rather than a single global instancenot Authelia

Where each one falls short

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

Authelia

  • Depends on a reverse proxy: it is not a standalone identity provider
  • Configuration is YAML-first with no administrative interface, so changes mean editing files
  • Not a full IAM: user management, provisioning and federation are limited compared with Keycloak
  • Scales poorly as an organisation-wide identity solution, which is not its target

Trend Micro Vision One

  • Licensing is a credit pool consumed at different rates by different modules, so forecasting a renewal means modelling which capabilities you will activate rather than counting users, and switching on a new module silently draws down the budget for an existing one.
  • Retention in the XDR data lake beyond the included window is bought with additional credits, so the retrospective hunting the platform is sold on is precisely the part with an ongoing meter attached, and teams shorten retention to control spend.
  • The correlation that justifies the platform only exists over deployed Trend sensors, so an organisation running only the endpoint agent gets an EDR with a large console, and reaching the advertised value means a de facto single-vendor commitment across email, network and workload.
  • Legacy management planes persist: Apex Central, Deep Security Manager and the older Cloud One consoles overlap with Vision One and migrations have run for years, so administrators frequently maintain two consoles for the same agents and learn both.
  • The agents hook file and network operations, so on build servers, database hosts and developer machines the overhead is noticeable, and the standard remedy is broad path exclusions that remove protection from exactly the directories where attackers stage tooling.

Answered from the vendors’ own pages

Authelia: Is Authelia free?

Yes, open source with no licence fee.

Trend Micro Vision One: What are Trend Micro Credits?

A single purchased pool of licensing units drawn down by whichever Vision One modules you activate, at different rates per module and per protected object. It replaces separate per-product subscriptions and shifts the forecasting problem onto you.

Authelia: Does Authelia need a reverse proxy?

Yes. It integrates through forward authentication with Nginx, Traefik, Caddy or HAProxy rather than sitting in front of traffic itself.

Trend Micro Vision One: Is this the same thing as Deep Security?

Not the same, but related. Server and workload protection in Vision One descends from Deep Security, and Trend has been migrating Deep Security and Cloud One Workload Security customers onto the Vision One platform. Existing Deep Security deployments still exist in the field.

Authelia: Authelia or Keycloak?

Authelia is far lighter and aimed at protecting self-hosted services behind a proxy. Keycloak is a full identity and access management platform, and much more to run.

Trend Micro Vision One: Does it replace my SIEM?

No. It correlates and retains telemetry from Trend sensors and selected third parties, but it is not a general-purpose log store for every system in the estate, and compliance log retention requirements are usually still met elsewhere.

Trend Micro Vision One: Do I have to use Trend endpoint protection?

To get real value, effectively yes. Third-party ingestion exists but the correlation quality depends on Trend's own sensor telemetry, and a Vision One deployment over someone else's endpoint agent is not what the platform is designed around.

Trend Micro Vision One: Where is the data held?

In the regional instance you choose at onboarding. Confirm the specific region against your residency obligations before deployment, because moving afterwards is a migration.
