The Microsegmentation Market and the Case for Zero Networks as the Optimal Solution

Author: John C. Fay MBE - March 2025

Introduction

As organisations continue to accelerate their digital transformation, cybersecurity has become a boardroom priority. Among the most significant threats facing enterprises today are ransomware, insider threats, and the movement of cybercriminals laterally through an organisation’s network. These threats pose a direct risk to the confidentiality, integrity, and availability of critical systems and data. A robust and effective security posture requires more than just perimeter defences—it demands a deep and granular level of protection within the network itself.

Microsegmentation is an increasingly adopted cybersecurity strategy that is pivotal in securing modern enterprise environments. By segmenting networks into smaller, isolated zones, Microsegmentation prevents attackers from moving laterally within the network, thus reducing the potential impact of a breach. While Microsegmentation offers significant benefits, its traditional implementation has been complex and costly.

This white paper explores the growing importance of Microsegmentation in today’s cybersecurity landscape, comparing various market solutions, and presenting Zero Networks as a leader in this field. Zero Networks offers a simpler, faster, and more cost-effective approach to Microsegmentation, making it the ideal solution for enterprises seeking to reduce risk and operational overhead.

The Threat Landscape: Why Microsegmentation is Critical

In today's threat landscape, a single compromised asset can result in devastating consequences. Cybercriminals increasingly exploit vulnerabilities to gain initial access to an organisation's network, often through phishing attacks or the exploitation of outdated systems. Once inside, they seek to move laterally across the network, gaining access to sensitive data, escalating privileges, and further infiltrating the organisation’s systems.

This lateral movement is one of the most dangerous and difficult-to-detect stages of a cyber attack. Attackers can maintain persistence within an organisation's network, escalating privileges, exfiltrating data, or deploying ransomware without being detected.

Microsegmentation significantly reduces the likelihood and impact of lateral movement. By isolating critical systems and segmenting networks based on business needs, organisations can limit access to sensitive data and systems, reducing the potential for a widespread breach. Microsegmentation effectively makes it more difficult for attackers to move freely within the network, thus containing and mitigating the impact of a breach.

Zero Networks: A Simplified, Automated Approach to Microsegmentation

Zero Networks, founded in 2019, has revolutionised the concept of Microsegmentation with a unified, automated, and agentless platform designed to simplify deployment and management. Traditional Microsegmentation solutions are often complex, requiring extensive professional services, agents on every endpoint, and a prolonged deployment period. Zero Networks has addressed these challenges by providing a solution that is intuitive, fast to deploy, and highly scalable.

Unlike traditional solutions that depend on manual policy creation and extensive configuration, Zero Networks uses artificial intelligence (AI) to automate the creation of segmentation rules and policies. This unique AI-driven approach significantly reduces deployment time and operational overhead, enabling organisations to implement Microsegmentation within just 30 days.

The Zero Networks platform is designed to seamlessly integrate with existing IT environments, whether on-premises, in the cloud, or in hybrid environments. With its agentless architecture, organisations can protect their network assets without the need to deploy agents on every endpoint, which reduces both the complexity and the management burden.

Key Benefits of Zero Networks

• Automated Deployment and Policy Creation: Zero Networks offers a fully automated deployment process, leveraging AI to create and maintain segmentation policies. This ensures that organisations can rapidly deploy the solution and avoid the need for manual configuration or expensive professional services.

• Agentless Architecture: Unlike many other Microsegmentation solutions that require agents on each endpoint, Zero Networks operates without agents, reducing the overhead and complexity of managing individual devices.

• Rapid Time to Value: With the ability to go live in just 30 days, Zero Networks provides a much quicker path to enhanced security compared to traditional Microsegmentation solutions, which can take months to deploy.

• Flexible Deployment Options: Whether organisations opt to deploy the solution in a data centre, cloud environment, or on-premise, Zero Networks supports all infrastructure models, providing flexibility and scalability.

• SaaS Delivery Model: Zero Networks uses a Software-as-a-Service (SaaS) model, which allows organisations to avoid the complexities of maintaining on-premise infrastructure, further simplifying their security strategy.

• Multi-Factor Authentication (MFA) Integration: A unique feature of Zero Networks is its ability to integrate MFA policies with network segmentation. This functionality applies MFA to any network destination, securing remote and internal assets without creating friction for users.

• Granular Control Over Privileged Accounts: The platform enables organisations to gain granular control over privileged accounts, third-party access, and operational technology environments, which are often prime targets for attackers.

• Unique RPC Firewall for Business-Critical Systems: Zero Networks includes a proprietary RPC firewall that safeguards Microsoft Domain Controllers and other critical servers, ensuring the integrity of core infrastructure and preventing unauthorised access.

Comparing Zero Networks with Other Microsegmentation Solutions

The Microsegmentation market is populated with several well-established solutions, each offering varying degrees of capability, flexibility, and complexity. Among the most recognised competitors are Illumio, VMware NSX, Cisco Secure Workload, Zscaler Workload Segmentation, and Tufin. Each of these solutions provides important functionality, but there are key differences in deployment ease, scalability, and operational efficiency.

• Illumio: Illumio is one of the most established players in the Microsegmentation market. It offers a comprehensive solution with robust visibility and policy enforcement capabilities. However, its reliance on agents and the need for extensive professional services can make deployment and management more complex and resource-intensive. Illumio is best suited for organisations with large, complex environments but may not be ideal for smaller or less resource-rich organisations.

• VMware NSX: VMware NSX excels in virtualised and hybrid environments, providing powerful segmentation capabilities for organisations using VMware infrastructure. However, its complexity, reliance on VMware technology, and the need for detailed configuration make it less suitable for enterprises with a more diverse infrastructure.

• Cisco Secure Workload: Cisco's solution is effective for managing Microsegmentation across hybrid environments, particularly in data centres and cloud-based workloads. However, Cisco Secure Workload requires careful integration with Cisco infrastructure and can be more challenging for organisations without an existing Cisco environment.

• Zscaler Workload Segmentation: Zscaler offers a cloud-native solution for workload segmentation, making it ideal for cloud-first organisations. However, it may not provide the same level of granularity or flexibility for on-premise and hybrid environments as Zero Networks.

• Tufin: Tufin focuses on policy management and security orchestration. While its policy engine is strong, Tufin's solutions are less automated and may require more manual intervention compared to Zero Networks, which leverages AI for continuous policy creation and segmentation.

Why Zero Networks Stands Out

While there are multiple solutions available, Zero Networks distinguishes itself by offering a fully automated, agentless, and cost-effective approach to Microsegmentation. The simplicity and speed of deployment, combined with the flexibility to work in on-premise, cloud, or hybrid environments, make Zero Networks a compelling choice for enterprises seeking a seamless security solution.

Moreover, Zero Networks supports organisations in their Zero Trust journey, ensuring that only authenticated and authorised users can access sensitive resources, thereby reducing the risk of lateral movement and insider threats.
