Whyauthhostinstead of self-hosting Authentik?
Authentik is great open-source software. But running an identity provider is business-critical – an outage means nobody can log in. Our expert team handles complete management — from setup through proactive monitoring to immediate incident response.
24/7 Monitoring & Incident Response
An identity provider must run around the clock. An outage means: nobody can log in – all applications stop.
Security Patches & Zero-Day Response
Identity providers are a prime target for attackers. Zero-day vulnerabilities require immediate action – 24/7.
Missing Expert Knowledge
OIDC, SAML, LDAP, flows, outposts, certificates – secure operation requires deep specialist knowledge most IT teams lack.
Hidden Operating Costs
Servers, monitoring, backups, personnel costs, on-call duty – the true costs of self-hosting quickly exceed any managed offering.
First-class Hands-on Support
Personal support from our expert team
Enterprise-Grade Security
Proactive patches, monitoring & incident response
Predictable Costs
One flat rate — no hidden personnel costs
