Business goals
One of the largest general insurers in the market undoubtedly understands the importance of managing risk. The company offers business and personal insurance services to nearly 9 million customers.
Managing its own cyber risk is critical to its aim to make the world a safer place.
Insurance firms are ripe for cyberattacks, with a wealth of policyholder data and personally identifiable information (PII) at stake. Accordingly, the company’s infrastructure and cloud services team has a definitive goal: stay out of high-profile breach news.
The insurer has a 160-year brand reputation to uphold, and 9 million reasons to invest in security capabilities that reduce cyber risk and enhance resilience to attacks. Accordingly, the company's infrastructure and cloud services team has a definitive goal: stay out of high-profile breach news.
Technology challenge
While integral to its impressive growth, the company’s mergers and acquisitions have expanded the insurer’s hybrid attack surface. Despite due diligence processes, risk is inherent to M&A activity.
“In scanning our environments, we discovered the critical need to remediate unpatchable vulnerabilities from acquired systems — and at large,” explains an Executive Manager of Infrastructure and Cloud Services for the firm. “Tighter security controls were vital to better protect our high-value applications and assets.”
“Since implementing Illumio, we've taken 5,000 exploitable vulnerabilities down to 9 across seven high-value applications and hundreds of workloads. It has proven to be invaluable to our risk mitigation strategy.”

The team sought microsegmentation to protect the application workloads underpinning the business and to limit exposure to vulnerabilities.
They had specific requirements for a safe, seamless approach that would not break applications or threaten uptime. That's where Illumio came in.
How Illumio helped
The insurer turned to Illumio Segmentation, which ticked all the boxes for “safe and seamless” in its proof of concept. Illumio’s Zero Trust Segmentation has proven value in spades since deployment.
By tightly controlling traffic to business-critical applications, the insurer eliminated thousands of vulnerabilities and reduced its exploitable attack surface by 99 percent.
"Since implementing Illumio, we've taken 5,000 exploitable vulnerabilities down to 9 across seven high-value applications and hundreds of workloads," the executive manager says. "Illumio has proven to be invaluable to our risk mitigation strategy."
Illumio's real-time traffic map serves as a constant source of security, helping the infrastructure and cloud services team understand connections between applications and visualize the impact of policies before applying them.
“Zero Trust Segmentation with Illumio Segmentation is a simple process,” explains the executive manager. “From an operational perspective, our number one goal is to never break production, which we achieved with Illumio. Our cyber operations governance board is extremely pleased.”
"From the beginning, there was a sense that the Illumio team would do whatever it takes to support our team. Time and again, they've proven exceptional in their responsiveness, expertise, and partnership."

Results and benefits
With segmentation controls as a foil against vulnerabilities and attackers, the company has gained assurance that the business’s high-value assets are protected.
The team also sees Illumio Core as complementary to other tools, particularly its endpoint detection and response (EDR) from CrowdStrike.
“Zero Trust Segmentation and EDR give us a powerful two-pronged approach for defending against attacks,” says a security services manager. “We know Illumio will proactively prevent a breach from spreading, and EDR can then do its job of detecting it and responding.”
The team is strategizing on how they will leverage more Zero Trust Segmentation capabilities in the future and know they can always count on Illumio’s partnership.
“From the beginning, there was a sense that the Illumio team would do whatever it takes to support our team,” he says. “Time and again, they’ve proven exceptional in their responsiveness, expertise, and partnership.”
