Transforming Identity and Access Management (IAM) for a healthcare multinational, migrating over 140 applications in a 12-week timeframe ![davita-logo-black-and-white](https://proofid.com/hs-fs/hubfs/davita-logo-black-and-white.png?width=2000&height=745&name=davita-logo-black-and-white.png) ![getty-images-atkFpTsfcug-unsplash](https://proofid.com/hs-fs/hubfs/getty-images-atkFpTsfcug-unsplash.jpg?width=1920&height=1253&name=getty-images-atkFpTsfcug-unsplash.jpg) Challenge ## As an international healthcare giant and a Fortune 500 company, DaVita’s IT demands are considerable. And with large numbers of employees operating all over the world, including at its headquarters in Denver, Colorado, ensuring fast, smooth and secure access to data and systems is essential. DaVita found that it needed to make improvements in its approach to Identity and Access Management (IAM). In particular, it required experience and resources to help it migrate a complex, legacy, and proprietary single sign-on (SSO) infrastructure. The ultimate goal was a standards-based SSO that could federate a wide range of SaaS and on-premise legacy applications without impacting users or affecting operations. ## How can SSO be transformed for a large-scale, international enterprise - without causing major business disruption along the way? ![ping](https://proofid.com/hubfs/ProofID%20-%202025/Images/ping.svg) Solution ## Putting the new building blocks in place - while keeping the old ones running for business continuity DaVita settled upon the PingFederate platform, developed by Ping Identity, as its SSO infrastructure solution of choice. This was implemented by ProofID, a Ping Identity-certified platinum partner with broad expertise with managing large and complex IAM projects. ProofID worked closely with DaVita’s in-house team to federate over 120 legacy applications and a further 20 SaaS applications. The development of backwards compatibility made for a ‘transition’ period of 12 weeks, in which the legacy SSO infrastructure remained in place in order to minimise business disruption. ![Counter Vector](https://proofid.com/hubfs/ProofID%20-%202025/Images/Counter%20Vector.svg) COMPANY FIGURES 0  Users migrated to the new SSO infrastructure across global operations.  0  Applications federated including 120 legacy and 20 SaaS applications.  0  Weeks transition period to migrate and deprecate the legacy SSO system.  0  Users migrated to the new SSO infrastructure across global operations.  0  Applications federated including 120 legacy and 20 SaaS applications.  0  Weeks transition period to migrate and deprecate the legacy SSO system.  Results ## A solid foundation for simple, secure SSO - both now, and in the future The federation was carried out successfully, and DaVita was confident and satisfied enough to deprecate the legacy SSO infrastructure 12 weeks after starting the project. ProofID also took the project further by developing a reference architecture and reference implementation for the office of the CTO and application development teams. The reference documentation provided a repeatable approach, accelerating deployment time of new applications. - Fast, smooth deployment - Minimal business disruption - Universal SSO across SaaS and legacy application - Reference documentation to support future integrations - Access to ProofID’s Ping Identity expertise ## “Only ProofID brought the industry experience, technology expertise and proven best practices necessary to transform our legacy infrastructure to a standards-based, scalable architecture. They provided the best value based upon the experience of the team, their ability to predictably deliver complex end-to-end systems and above all their relationship and certification by Ping Identity.” Identity Architect DaVita Identity Architect DaVita ## Highlighted case studies ![](https://proofid.com/hubfs/Nelnet_White.png) ![Identity and access management technology](https://proofid.com/hubfs/brooke-cagle--uHVRvDr7pg-unsplash.jpeg) 1 Aug 2025 - 2 min read ### Identity and access management technology ![](https://proofid.com/hubfs/Denver%20White%20Logo-1.png) ![Making identity and access management a success in the “Mile High City”](https://proofid.com/hubfs/jakob-rosen-7C00d3z3ssU-unsplash.jpeg) 1 Jul 2025 - 2 min read ### Making identity and access management a success in the “Mile High City” ![](https://proofid.com/hubfs/ProofID%20-%202025/Images/Tesco%20bank.svg) ![Banking customers can count on: unified identity in finance with Ping Identity, ProofID and Tesco Bank](https://proofid.com/hubfs/ali-mkumbwa-OnRPps1wPus-unsplash.jpg) 9 May 2025 - 2 min read ### Banking customers can count on: unified identity in finance with Ping Identity, ProofID and Tesco Bank ![](https://proofid.com/hubfs/immedis_logo.png) ![Making Immedis’ onboarding and identity access faster - without compromising sensitive data security](https://proofid.com/hubfs/christina-wocintechchat-com-glRqyWJgUeY-unsplash.webp) 10 Apr 2025 - 2 min read ### Making Immedis’ onboarding and identity access faster - without compromising sensitive data security GET STARTED ## Let's talk about your project We're ready to discuss your needs and explore how we can help you achieve your goals.
