Identity: Self-hosted or in the cloud?

authentik is an open source Identity Provider that unifies your identity needs into a single platform, replacing Okta, Active Directory, and Auth0. Authentik Security is a public benefit company building on top of the open source project.


In October 2023, Cloudflare announced that they had discovered yet another Okta compromise.

Cloudflare had to warn Okta first and show them how they had been breached via an insecure setup with a third-party service provider. A leading company offering security and identity as a service instead introduced insecurity.

Over the past decade or so, SaaS has become the dominant model for delivering software, and yet, such incidents aren’t surprising. The SaaS business model was supposed to align vendor and customer interests, while the technology allowed rapid updates and improvements. SaaS was supposed to bring an end to throwing software over the wall and letting customers deal with it.

Recently, however, we’ve seen many companies fleeing SaaS providers to build private clouds and run self-hosted software. At Authentik Security, we have seen more and more customers canceling legacy SaaS providers to take back control of their identity needs with our self-hosted solution.

At first glance, it looks like people are going back in time, but self-hosted software has advanced despite the popularity of SaaS and is increasingly likely to beat SaaS options across numerous measures. In this post, I’ll walk through why the industry defaults have changed and why we believe in focusing on a self-hosted product.

The XZ backdoor incident spooked a lot of people. Not all PRs are innocent—even from long-standing contributors—and this one would have created a backdoor in a utility included in almost all Linux distributions, had it not been caught.

But “open source = more vulnerable to exploits” is the wrong takeaway—being open source can actually be an advantage for security-focused products.

We need to talk about SCIM: More deviation than standard

As a young security company, we’ve been working on our implementation of SCIM (System for Cross-domain Identity Management), which I’ll share more about below. SCIM is in many ways a great improvement on LDAP, but we’ve run into challenges in implementation and some things just seem to be harder than they need to be. Is it just us?

Black box security software can’t keep up with open source

Legacy security vendors that rely on black box development can't keep up with open source. It's an oft-discussed topic—the ability of open source communities to quickly jump in and collectively solve problems and innovate solutions—but it is equally believed that "serious" security software companies have proprietary software.

In this blog, we will take a closer look at the pros and cons of the various source availability types of SSO and other security software.

Announcing the authentik Enterprise release!

📣 We are happy to announce that the first authentik Enterprise release is here! 🎉

The Enterprise release of authentik provides all of the functionality that we have spent years building in our open source product, plus dedicated support and account management. This Enterprise version is available in Preview mode in our latest release, 2023.8.

This is an exciting step for us, as we grow the team and the company and our user base. We officially became a company just last fall (I wrote about it in November 2022, in “The next step for authentik"), and this release is another move forwards in maturing authentik into the SSO and identity management app of choice.

One thing we want to acknowledge, up front, is that we would never have been able to achieve this goal without the years of support from our open source community. You all helped build authentik into what it is today, and that’s why all of our Enterprise-level features will be open core and source available, always.
