a major insurance company shrinks hybrid attack surface by 99% with Illumio

A large insurance company faced the challenge of securing a complex hybrid environment expanded through mergers and acquisitions. It needed to mitigate risk from thousands of unpatchable vulnerabilities and protect high-value applications without disrupting critical production services. They turned to Illumio to implement its Zero Trust Segmentation solution.

Illumio provided safe and seamless microsegmentation, giving the insurer real-time visibility and granular security controls. The solution reduced the company's exploitable attack surface by 99 percent, taking 5,000 vulnerabilities down to just 9 across seven critical applications and hundreds of workloads. Illumio enabled this protection without breaking applications, providing a foundational layer of security complementary to other tools like endpoint detection and response.
