5 Real Reasons Why Microsegmentation Projects Fail—and How Zero Networks Solves Them
Published February 21, 2025

Microsegmentation has become a cornerstone of Zero Trust architectures, promising granular control over network traffic and significantly reducing attack surfaces. Yet, despite its potential, many microsegmentation projects stall or fail outright, to no fault of those implementing the solution (though some vendors, regardless of the complexity of their own solutions, prefer to blame their users). Understanding why these initiatives falter is the first step toward finding a solution – that’s where Zero Networks comes in.
Common Pitfalls in Microsegmentation Projects
1. Complexity Overload
Implementing microsegmentation is inherently complex. Organizations often struggle with mapping out every application dependency and network flow. Manually creating tags or labels for every asset is time-consuming and labor-intensive. Traditional solutions require manual policy creation, leading to misconfigurations and endless rule tweaking.
According to a recent Zero Trust industry report, 70% of cybersecurity professionals agree that microsegmentation is very important or essential for achieving Zero Trust, but only 5% of respondents are microsegmenting their networks today. Forty percent cited complexity as the top concern with implementing microsegmentation.
2. Resource Constraints
Microsegmentation projects demand significant time, specialized expertise, and financial investment. Many IT teams are already stretched thin, making it difficult to allocate the necessary resources for successful implementation.
3. Operational Disruption
One of the biggest fears with microsegmentation is breaking critical applications. Poorly configured policies can inadvertently block legitimate traffic, leading to downtime and user frustration. This risk often causes teams to hesitate or abandon the project entirely.
4. Scalability Challenges
As environments grow – especially with the rise of hybrid and multi-cloud infrastructures – maintaining and scaling microsegmentation policies becomes exponentially harder. Traditional solutions struggle to adapt, leading to gaps in security.
5. Lack of Visibility
Without comprehensive visibility into network traffic and application dependencies, creating effective segmentation policies is a guessing game. Blind spots can result in both security gaps and operational issues.
How Zero Networks Solves These Challenges
Zero Networks was designed to address the very issues that cause microsegmentation projects to fail. Here’s how:
1. Automated Policy Creation
Zero Networks monitors and learns all network connections over a period of 30 days to create deterministic, highly accurate firewall rules and policies. This eliminates the need for manual tagging, grouping, and policy writing, drastically reducing the complexity of implementation, ongoing management, and risk of misconfiguration.
2. Agentless and Scalable
With an agentless approach, Zero Networks can be deployed quickly across diverse environments without the overhead of installing software on every endpoint. Its scalable architecture ensures consistent policy enforcement across on-premises, cloud, and hybrid infrastructures.
3. Minimized Operational Risk, Maximized Cyber Resilience
Zero Networks employs adaptive policies that adjust in real time, ensuring that legitimate traffic isn’t inadvertently blocked. This reduces the risk of downtime and keeps critical applications running smoothly. If a breach occurs, it’s immediately contained, allowing an organization to keep operations running smoothly and bounce back extremely quickly from an event.
4. Enhanced Visibility and Control
The platform provides comprehensive visibility into network traffic, making it easier to identify dependencies and potential risks. This insight allows for more informed policy decisions, leading to more effective segmentation.
5. Cost and Resource Efficiency
By automating much of the heavy lifting, Zero Networks reduces the need for specialized personnel and long project timelines. This not only cuts costs but also accelerates time-to-value. ESG recently validated the cost savings from Zero’s automations and found that the average enterprise saves 87% with Zero compared with traditional firewall segmentation and 75% when compared to legacy microsegmentation platforms.
Conclusion
Microsegmentation is vital for modern network security, but traditional approaches often fall short due to complexity, resource demands, and scalability issues. Zero Networks offers a smarter, more efficient path to achieving effective microsegmentation, helping organizations realize the promise of Zero Trust without the typical pitfalls.
If your microsegmentation project has stalled – or you’re considering starting one – Zero Networks could be the solution that ensures your success.
