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

SentinelOne Singularity

  • Deployment and configuration requires professional services ($5,000 to $25,000)
  • Optional modules like Ranger and Vigilance add to total cost of ownership
  • Complex pricing tiers make budgeting difficult for large deployments

Answered from the vendors’ own pages

Authelia: Is Authelia free?

Yes, open source with no licence fee.

SentinelOne Singularity: What does SentinelOne Singularity XDR cover?

Singularity XDR unifies detection and response across endpoints, cloud, identity, network, and mobile, providing centralized visibility and automated response across all attack surfaces.

Source
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.

SentinelOne Singularity: How does SentinelOne correlate data across security tools?

Singularity normalizes data from endpoints, identity, cloud, and third-party security tools into a unified data layer, enabling automatic correlation of signals without manual integration.

Source
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.

SentinelOne Singularity: Can SentinelOne integrate with existing security tools?

Yes, Singularity Marketplace provides pre-built, one-click integrations with email, network, firewall, and SaaS security tools, avoiding vendor lock-in while extending detection capabilities.

Source
SentinelOne Singularity: What is the pricing model for SentinelOne Singularity?

SentinelOne pricing ranges from $5.83 to $17.50 per endpoint per month across five tiers, with optional add-on modules and enterprise pricing available on request.
