The OT cyber risk in modern buildings
Legacy Building Management Systems and operational technology were engineered for availability, not today’s adversarial environment. Unsecured edge devices and controllers leaves critical facilities exposed to modern cyber threats that bypass traditional IT defenses.
What’s at stake
- Business impact: Unplanned downtime and operational failure.
- Human safety: Compromised environmental and physical controls risks put humans in jeopardy.
- Compliance: Emerging cybersecurity mandates expose organizations to audit liabilities.
What’s broken today
- Network Exposure: Extensive use of unprotected broadcast and discovery protocols allowing device penetration and lateral threat movement.
- Shared credentials: Edge devices require on-device admin credentials for recovery and reset. Even when user access is managed these credentials mean there is a high privileged back door that is not secured by traditional IT access controls.
- Self-signed or static certificate management: resulting in unsecured systems and lack of recovery and protection agility at scale.
Built for the OT ecosystem
Zuul provides a specialized security framework designed for the unique requirements of every stakeholder in the cyber-physical infrastructure lifecycle.
Building owners and Operators
Gain visibility, enforce security standards, and reduce infrastructure risk across facilities.
System integrators
Deliver secure deployments faster with repeatable, policy-driven infrastructure templates.
OEM & technology partners
Embed secure provisioning and certificate management into next-generation systems.
Zuul OT Security Platform
A single control plane to secure BMS and cyber-physical systems across your portfolio.
Policy-Based State Enforcement
Zuul continuously verifies and enforces the defined ‘target state’ of every endpoint.
- Monitor and Manage state controls
- Whitelisted executable enforcement
- Configuration drift correction
- Automated remediation within minutes
- Prevents service technicians or malicious software from achieving privileged access at the edge and overriding critical security controls.
Identity-Driven Zero Trust
Zuul delivers frictionless enforcement of configuration, authentication and policy compliance by every device, user, and service. Applying these at a granular level makes unauthorized access attempts easier to block and anomalous network behavior become easier to detect.
- Private PKI & certificate lifecycle automation
- mTLS for BACnet/SC and web interfaces
- Root account protection
- User and M2M credential management
Secure-by-Design Architecture
Zuul partners directly with OEMs to model every security control available on each device type. Security is not layered on — it is embedded in the device, templated, and enforced based on deep device knowledge.
- Pre-configured hardened defaults
- Device-specific security models
- Reduced configuration errors
- Complete control coverage
- On-edge management and enforcement
Automated Response & Recovery
When deviation occurs, Zuul can restore devices to a secure state in minutes.
- Alerts are sent
- Certificates are easily revoked and re-keyed
- Password rotation across fleet
- Device isolation
- Bulk remediation actions
Continuous Compliance & Live ATO
Zuul translates deployment models into machine-readable policy artifacts that support continues monitoring, automated compliance documentation, and continuous assessment.
- Alignment to NIST 800-82r3 & ISA/IEC 62443
- Self-generating compliance documentation
- Deployment-specific JSON artifacts
- Continuous validation dashboards
Explicit Whitelist Driven Network Defense
Zuul calculates authorized device relationships and approved protocol behavior — anything outside that model is flagged or blocked.
- Approved device-to-device relationships
- Protocol and port whitelisting
- Unauthorized traffic detection
- Passive network monitoring with high signal-to-noise ratios
- Ability to export to IT SEIMs
