The Challenge
A Fortune 100 healthcare service sold a part of their business and associated infrastructure to a foreign entity. Both businesses needed to realize the synergies immediately. However, without an understanding of how the company’s own applications were interconnected, their teams were unsure of what part of their IT infrastructure the new acquirer potentially touched and risked breaking business-critical applications by arbitrarily cutting communications. The company’s attempts to identify application dependencies using the network provided limited visibility, preventing them from confidently segmenting the acquired assets.
About The Customer
The customer is a Fortune 100 healthcare service that recently sold a part of their business and associated infrastructure to a foreign entity. The company has a complex IT infrastructure with interconnected applications, which posed a challenge when the new acquirer wanted to integrate its purchase immediately. The company's teams were unsure of what part of their IT infrastructure the new acquirer potentially touched and risked breaking business-critical applications by arbitrarily cutting communications. The company needed a solution that would allow them to understand their application dependencies and segment the acquired assets confidently.
The Solution
The company chose the Adaptive Security Platform by Illumio. Leveraging the real-time application dependency map, IT teams could quickly understand system communication flows and segment them confidently. This allowed the acquirer exposure to relevant assets within their data center while locking down any systems access outside the scope of the divestiture. The business could proceed in gaining ROI for its investment, chalking up a win for the divestiture team. The networking team avoided re-architecting – or even touching – the network. Security teams rested easy with the protection of ringfencing their data center assets through segmentation, avoiding a potential high-profile fire drill – or worse yet, a bet-the-business breach.
Operational Impact
  • Just-in-time deployment: The team prevented unauthorized network movement with a low administrative burden through Illumio’s plug-and-play solution, delivering superior ease of use for policy administration.
  • Real-time visibility to design safer security: The team used an intuitive real-time application dependency map to segment the environment and build effective policies, eliminating inflexible constructs like VLANs, zones, overlays, subnets, or IP addresses.
  • Tackle vulnerabilities with ease: Security teams could now view highly exposed workloads and remediate an attacker’s potential lateral pathways through the real-time application dependency map’s ability to display vulnerabilities between and within applications.
