Zero Networks: The Premier Solution for Agentless Microsegmentation & MFA

by John C. Fay MBE, CEO of XypherSecurity – 7th April 2025

Scene Setting: Zero Trust and Microsegmentation

The cybersecurity threat landscape has substantially evolved over the past five years, propelled by multiple critical factors. Among these factors is the notable escalation in ransomware attacks, which have become progressively sophisticated, pervasive, and damaging. Current ransomware operations encrypt data and exfiltrate sensitive information to impose additional pressure on victims. This dual-threat methodology has significantly intensified organisations' financial and operational repercussions worldwide.

A critical strategy utilised by cyber adversaries encompasses lateral movement techniques, which facilitate navigating and elevating privileges within a network after obtaining initial access. This methodology significantly amplifies the severity and breadth of breaches. Compromised privileged credentials are integral to this process, as they afford attackers the requisite access to manoeuvre through systems undetected, thereby permitting more profound infiltration and extensive damage.

Considering the evolving threats associated with cybersecurity, micro-segmentation has emerged as an essential strategic approach. This methodology involves the segregation of network workloads and applications, thereby substantially limiting adversaries' capacity to perform lateral movements. By establishing secure rules within offices, data centres, and cloud environments, micro-segmentation ensures that potential threats are promptly identified, contained, and neutralised, thereby enhancing the overall resilience of the network.

The Zero Difference

Microsegmentation has long been considered a complex and challenging undertaking, but Zero Networks has transformed this paradigm. Drawing from extensive feedback from hundreds of clients, Zero Networks has developed a solution that overcomes the limitations inherent in traditional Microsegmentation products.

Redefining the principles of least-privilege architecture, Zero Networks delivers an agentless, automated, and scalable solution that enforces robust access controls without the complexity and operational burden typically associated with legacy Microsegmentation approaches.

Executive Summary

In an era characterised by hybrid and highly interconnected environments, traditional perimeter security measures have become increasingly insufficient. The rise of lateral movement in cyberattacks has exposed the weaknesses in conventional segmentation strategies, leaving organisations vulnerable to internal threats.

Zero Networks introduces a paradigm shift in network security by offering an agentless, automated Microsegmentation solution, complete with integrated Multi-Factor Authentication (MFA). This approach facilitates secure connectivity across any environment—on-premises, in the cloud, or in hybrid infrastructures—without the need for manual policy creation, agent installations, or network disruptions.

The Challenges of Legacy Microsegmentation

Despite its importance in contemporary cybersecurity frameworks, Microsegmentation has historically been challenging to implement due to several key limitations:

• Agent Dependency: Legacy solutions require endpoint agents, often introducing compatibility issues, performance degradation, and significant deployment friction.

• Manual Policy Creation: The creation and management of granular access policies manually is not only time-consuming but also prone to human error and inefficiencies.

• Scalability Issues: Traditional tools frequently struggle to scale effectively in dynamic, hybrid, or cloud-based environments.

• Suboptimal User Experience: Legacy Microsegmentation methods often disrupt workflows and introduce operational overhead, hindering organisational efficiency.

Why Zero Networks Is the Solution of Choice

1. Truly Agentless by Design - Zero Networks eradicates the need for endpoint agents or network modifications. By utilising existing infrastructure, it enforces rigorous access policies at both the host and network level, delivering enterprise-grade segmentation with no impact on performance or compatibility.

2. Autonomous Policy Generation - Zero Networks' patented technology learns communication patterns autonomously, dynamically generating least-privilege access policies for every asset in the system. What would traditionally take months of manual effort now occurs in mere days—without human error or guesswork. 

3. Integrated Multi-Factor Authentication (MFA) - Zero Networks is the only Microsegmentation solution that incorporates MFA directly into network access controls. By enforcing identity-based authentication for all connections—whether RDP, SSH, or SMB—Zero Networks integrates identity verification seamlessly into network security protocols.

4. A Unified Platform for Any Environment - Whether your workloads reside on-premises, in the cloud, or across hybrid systems, Zero Networks adapts effortlessly without requiring infrastructure redesign. It is cloud-native, hybrid-ready, and designed to integrate seamlessly with your existing ecosystem, including firewalls, SIEMs, identity providers, and more.

5. Zero Trust Made Practical - Zero Networks enables organisations to implement Zero Trust principles with ease. Rather than necessitating a complete overhaul of your security architecture, our solution allows you to deploy Zero Trust incrementally—asset by asset, application by application—achieving measurable risk reduction from day one.

Proven Outcomes

Organisations that have adopted Zero Networks report substantial improvements in their security posture, including:

• A 90%+ reduction in attack surface

• Zero lateral movement post-deployment

• Rapid deployment, taking days rather than months

• Up to 70% reduction in operational overhead

• Unmatched user and system compatibility

Testimonials

“Our deployment of Zero Networks enabled us to implement Microsegmentation across our entire network without installing a single agent. We were up and running in under a week.”— CISO, Fortune 500 Healthcare Provider

“The built-in MFA at the network layer is a game-changer. We no longer rely solely on VPNs or user awareness—Zero Networks made Zero Trust a practical reality for us.”— Director of IT Security, Global Manufacturing Firm

Conclusion

Zero Networks has set a new benchmark in the industry for Microsegmentation and access control. By overcoming the key challenges of legacy solutions—complexity, agent dependencies, and scalability limitations—Zero Networks offers a streamlined, agentless path to Zero Trust security. It is a solution that works seamlessly across modern, dynamic environments, providing a frictionless and highly effective approach to securing the network.

If you are ready to protect every asset, enforce least-privilege access by default, and eliminate lateral movement, Zero Networks is the solution for you.
