I would like to highlight a digital transformation that I have witnessed and contributed to since a few years now. This transformation is about the adoption of standards based software to achieve Single Sign On (SSO) in enterprise environments, replacing legacy vendor systems that have been around for a decades.
About 20 years ago companies started to implement intra-enterprise SSO based on vendor proprietary mechanisms and protocols. This comes with a strong dependency on the vendor and over the years thereafter in most cases it resulted in extremely high costs in licensing, infrastructure and professional services.
In addition, the legacy mechanisms are often based on enterprise-wide cookies which makes them vulnerable to user impersonation attacks, especially from insiders, and also makes it hard to move applications into the cloud.

On top of that, many legacy systems would come with proprietary “agent” software that has strong a dependency on (a specific version of) the policy server from the same vendor, making upgrades very painful and time consuming. Implementing an open standard reduces that dependency and makes it easier to apply upgrades or switch between vendors.
I have observed that the biggest uptake of the OpenID Connect standard recently is in enterprise SSO, replacing legacy vendor proprietary systems and I am happy be able to contribute to that in the form of open source software for a variety of web servers and reverse proxies. Please reach out to me if you think this software can be useful for your business as well.
