Zero-Trust Network Access Explained

ZTNA is the modern approach to secure connectivity. Instead of granting blanket access like VPNs, Zero-Trust validates every user, device, and request before access is given. It enforces the principle of "never trust, always verify," ensuring that building automation systems, IoT devices, and critical infrastructure are accessible only to those who need them, and only for as long as they need.

How Zero-Trust Works

  • Least-Privilege Access

    Users and vendors receive only the access they need — no more, no less.

  • Continuous Verification

    Every session is monitored and re-validated to prevent abuse.

  • Micro-Segmentation

    Networks are divided into secure zones, preventing attackers from moving laterally.

  • Strong Identity Verification

    Multi-factor authentication and device posture checks ensure identity and device integrity.

  • End-to-End Encryption

    All communication is encrypted, keeping sensitive data secure.

Why Building Portfolios Need Zero-Trust

Zero-Trust enables owners to modernize security without ripping and replacing legacy systems. By layering ZTNA over existing building automation and OT systems, operators gain stronger protection against ransomware, downtime, and compliance failures.

  • Modernize Without Replacing

    Layer ZTNA over existing building automation and OT systems

  • Reduce Costs

    Lower operational expenses and minimize downtime from security incidents

  • Simplify Vendor Access

    Easily manage and monitor third-party access to building systems

The result is reduced costs, simplified vendor access management, and peace of mind that systems are secure in today's high-risk environment.

Why VPNs Fail in Today's Cyber Landscape

VPNs were built for an era of simpler IT networks. As AI accelerates the speed and complexity of cyberattacks, VPNs have become a liability for building owners, creating more risk than protection.

Broad Network Access

VPNs expose entire subnets once connected, making lateral movement easy for attackers

Weak Authentication

Often relies on simple credentials; even MFA has been bypassed in recent attacks

Poor Visibility

Minimal logging and monitoring capabilities leave blind spots in security posture

AI-Accelerated Threats

Modern attacks move faster than VPN security models can respond
