Zero Trust Segmentation

Illumio Recognized in Two Gartner® Hype Cycle™ Reports

Cyber threats are changing quickly – and cybersecurity technologies must keep up. But traditional prevention and detection technologies aren’t enough to stand up against today’s ever-changing threats.

As a result of these challenges, security teams are turning to Zero Trust security strategies.

According to Gartner, “Zero Trust is becoming a requirement in data center design, and microsegmentation is a practical way to accomplish this.”

In both the Hype Cycle for Enterprise Networking, 2023 and the Hype Cycle for Zero Trust Networking, 2023 reports, Gartner recognized microsegmentation, also called Zero Trust Segmentation, as a:

  • High-benefit technology
  • Expected to achieve mainstream adoption within the next two years
  • On the Gartner Hype Cycle Slope of Enlightenment to offer real-world adoption and benefits

Why we believe Gartner recommends Zero Trust Segmentation to stop the spread of breaches

At its core, Zero Trust Segmentation (ZTS) goes beyond the limitations of traditional network segmentation to stop the spread of ransomware and breaches.

According to Gartner, “As servers are being virtualized, containerized, or moved to infrastructure as a service (IaaS), existing safeguards such as traditional firewalls, intrusion prevention solutions, and antivirus software struggle to follow the fast pace of deployment for new assets.”

The changes brought by rapid digital transformation have left organizations vulnerable to attackers who can easily and quickly get past traditional detection and prevention tools. Without ZTS, breaches can enter the network and then immediately move laterally, causing widespread – and often catastrophic – cyber incidents.  

This is especially true as organizations scale their networks. Gartner notes: “The increasingly dynamic nature of data center workloads makes traditional network-centric segmentation strategies difficult to manage at scale, if not impossible to apply.”

With ZTS, organizations can secure large, complex, and growing environments by building granular and adaptable access policies. A key part of this is visibility – Gartner recommends platforms that offer visibility into all communication and traffic between workloads and devices across the entire hybrid attack surface.

“Some microsegmentation products provide rich application communication mapping and visualization, allowing data center teams to identify which communication paths are valid and secure,” Gartner says.

Ultimately, ZTS helps build a security posture that is more responsive to today's dynamic threat environment.  

As Gartner explains, “Once a system is breached, attackers move laterally (including in ransomware attacks), which can cause serious damage. Microsegmentation seeks to limit the propagation of such attacks. It can greatly reduce the initial attack surface as well.”

Why choose Illumio for Zero Trust Segmentation

Gartner sees organizations taking an increased interest in visibility and granular segmentation for east-west traffic between applications, servers, and services.

With Illumio ZTS, you can quickly and easily:

  • See risk: See risk by visualizing all communication and traffic, both known and unknown, between workflows, devices, and the internet.
  • Set policy: With every change, automatically set granular segmentation policies to control unnecessary and unwanted communications.
  • Stop the spread: Automatically isolate compromised systems and high-value assets in minutes to proactively stop the spread of a breach or reactively during an active attack.
The Illumio Zero Trust Segmentation Platform

In just a few hours, security teams can use Illumio’s real-time application dependency map to see traffic between workloads and devices across the entire hybrid attack surface. Illumio's agnostic approach to the underlying network infrastructure ensures an elevated level of visibility, a feature that we believe aligns with the “rich application communication mapping” Gartner recommends to pair with ZTS implementations.

Leveraging insight from the application dependency map, organizations can proactively identify and secure potentially hazardous or outdated pathways and ports. This strategic isolation of critical assets forms a robust defense mechanism against the lateral movement intrinsic to breach and ransomware. We feel it also aligns with the Gartner report’s user recommendation to “target the most critical assets and segment them first.” Within this framework, Illumio allows you to set basic security policies that can be progressively scaled to granular levels whenever needed.

Scaling segmentation policies is streamlined by Illumio's Policy Generator which alleviates the complexities often associated with this task. Through automated recommendations of optimized segmentation policies tailored to diverse workload scenarios, including containers, virtual machines, and bare metal systems, the Policy Generator simplifies what was once a resource-intensive process.

Importantly, Illumio ZTS pivots from traditional reliance on IP addresses or network locations to a more intuitive label-based system. This aligns with Gartner's recommendation to “use the identities of applications, workloads, and services – either via logical tags, labels, fingerprints or stronger identity mechanisms.” Illumio’s policies will follow workloads wherever they go across different hybrid and multi-cloud environments.
