Microsegmentation Vendor Evaluation Guide: Key Features for Zero Trust Security

It takes organizations an average of 241 days to identify and contain a breach, but cyber attackers now begin moving laterally in as little as 51 seconds after gaining initial network access. As security teams struggle with overwhelming alert volumes, sprawling hybrid networks, and increasingly sophisticated threats, organizations can no longer afford to rely on detection-based strategies that always leave them one step behind hackers.  

Today, the question isn’t if a breach will happen, but when? And how far will it spread? Preventing lateral movement to instantly contain threats is key – and microsegmentation is the gold standard in real-time breach containment.  

Still, not all microsegmentation solutions are created equal – to avoid the implementation complexity, rearchitecting, and manual effort of legacy microsegmentation, learn which key capabilities define the most effective microsegmentation solutions today and get a practical checklist for evaluating vendors.  

What to Look for in a Microsegmentation Solution 

Over 95% of security leaders agree microsegmentation is key to strengthening cyber defenses, yet just 5% of organizations are microsegmenting their networks today. The reason for the disconnect? Until recent years, microsegmentation was too difficult for most security teams to deploy and scale.  

Legacy Microsegmentation: Implementation and Scalability Challenges  

Concerns about implementation complexity and costs, disruption to existing operations, dealing with legacy applications, ongoing maintenance, and more have long left security teams with the impression that microsegmentation is an unattainable gold standard.  

Legacy segmentation solutions relied on network-level controls or agents deployed on endpoints to implement policies. These approaches were complex to deploy and maintain, introducing a significant manual burden for security teams. Now, modern microsegmentation solutions have evolved beyond legacy challenges thanks to a handful of key features.  

The Top 3 Microsegmentation Capabilities for Innovative Solutions 

According to industry research, security leaders want microsegmentation solutions to be automated, agentless, and identity-aligned.  

Agentless Management of Native Controls  

To avoid the implementation complexity and operational disruption of legacy solutions, a ViB Tech survey found that over two-thirds of security leaders are highly motivated to embrace microsegmentation without agents – more than 80% consider agentless deployment an important factor when selecting a microsegmentation solution.  

Rather than deploying software on every host or relying on specialized hardware, modern microsegmentation solutions should automatically orchestrate the native controls that already exist in today’s networks, enabling an agentless approach to comprehensive protection.  

Security leaders like Henry Mayorga, CISO at Baron Capital, consider this “living off the land” approach to microsegmentation vital:   

Automated Asset Discovery and Policy Creation 

Research from Enterprise Management Associates (EMA) on the maturing microsegmentation market found that security leaders value robust automation capabilities in modern microsegmentation solutions.  

When asked about the important differentiators between leading microsegmentation solutions and legacy approaches in the next 1-2 years, respondents prioritized fast, automated asset discovery and tagging that scales with growing environments, as well as automated policy creation and lifecycle management that reduces manual effort and ensures consistent enforcement. 

ViB Tech research echoes the importance of automation, with 88% of security leaders ranking automated policy creation as an important factor when selecting a microsegmentation solution.  

Similarly, CISA’s latest Microsegmentation in Zero Trust guidance highlights the need for segmentation policies that evolve dynamically using contextual data, and Gartner’s 2025 Hype Cycle for Workload and Network Security recommends that organizations seek a microsegmentation solution that maps application paths and makes policy recommendations leveraging automation. 

Integrated Identity-Based Controls  

Implementing advanced identity controls to secure privileged access is a top priority for security teams today – that’s why integrated multi-factor authentication (MFA) is a key capability defining the most innovative microsegmentation solutions.  

About 87% of cyber pros say integration with MFA to secure privileged access is a differentiator for innovative microsegmentation solutions; roughly the same percentage consider MFA overlay an important factor in solution selection – 54% consider it very important.  

Taken together, insights like these provide a clear roadmap for security leaders seeking an industry-leading microsegmentation solution.  

8 Key Questions to Ask Microsegmentation Vendors 

To ensure you’re investing in a modern microsegmentation solution that ticks all the right boxes, ask these questions when evaluating microsegmentation solutions:  

1. Is it easy to use?  

Historically, deploying a microsegmentation solution meant complex configurations and ongoing manual effort. A modern solution should offer an easy, scalable implementation where asset tagging, grouping, and policy creation and maintenance are accurately automated, eliminating time-consuming and error-prone manual processes.  

2. Is it effective?  

It’s easy to be distracted by shiny, clickable maps, color-coded statuses, and seemingly unlimited external integrations, but security leaders should stay focused on one essential goal when it comes to microsegmentation: protect every asset and prevent lateral movement.  

A modern solution should be able to segment 85% of your network – or more. For example, Zero Networks customers typically achieve 90% segmentation coverage within 90 days.  

3. Does it require any additional resources?  

Today’s security teams are stretched thin; that means no extra resources to manually configure segmentation. A modern microsegmentation solution should save both time and money – not eat up more of it. In fact, Zero saves the average enterprise 87% on OpEx costs when compared with traditional segmentation thanks to its effortless management and scalability.  

4. Will it start working quickly?  

CISOs and security teams need to show quick wins, so fast deployment cycles are now a necessity rather than a nice-to-have. This means a good solution promises fast deployment, no agents, and no lengthy configurations. For example, Zero’s agentless architecture deploys in minutes by leveraging native, host-based firewalls. 

5. Does it offer heterogeneous segmentation?  

A segmentation solution shouldn’t force you to decide between sequestering users, clients, or servers. A modern approach should do it all – taking a heterogeneous approach to segmentation and offering a single point of control, both in cloud and on-premises environments. 

6. Is it IT/OT agnostic?  

IT/OT convergence is on the rise, introducing new security risks as 70% of OT breaches begin in IT. Look for a solution that’s configured to work in both IT and OT environments rather than requiring separate approaches to segmentation.  

7. Does it offer continuous segmentation?  

Modern networks are dynamic – by the time you discover everything in your environment, it has changed. A microsegmentation solution should automatically and continuously observe network access to identify the connections necessary for day-to-day activity, ensuring policies stay up to date.  

8. Does it integrate with existing infrastructure?  

The risk of disrupting business operations is a non-starter for most organizations. A good microsegmentation solution should be engineered to ensure easy integration with existing IT infrastructure to guarantee that typical network usage patterns remain unaffected.
