Secure OT/IoT Access
Protect access to OT and IoT networks without disrupting productivity or operations.
Control Access to Critical OT and IoT Systems
OT and IoT systems often rely on legacy protocols with minimal built-in protections, making secure access challenging without negatively impacting operations. AppGate ZTNA addresses this by cloaking critical control systems and enforcing identity- and policy-driven access, ensuring only authorized users and applications can communicate with sensors, controllers, and data collectors. This reduces exposure, prevents unauthorized access, and maintains operational efficiency.
- Cloaked Resources: OT and IoT resources remain invisible until authenticated and authorized.
- Identity-Centric Access: Access is granted based on device identity, user context and risk posture, not just network location.
- Dynamic Policy Enforcement: Policies respond to device posture and activity to maintain secure access.
- Seamless Integration: Integrates with existing security tools for improved monitoring and operational oversight.
Implementation Steps
AppGate ZTNA simplifies the secure connection of OT and IoT environments by configuring connectors, defining policies, and monitoring traffic for optimal performance.
1 Configure Connectors
Establish secure tunnels for OT and IoT devices, ensuring encrypted communication.
2 Define Device Policies and Entitlements
Create policies and entitlements that specify access rules for each device type, including fallback options.
3 Set Up IP Pool Mapping
Assign unique IP addresses to each device type, preventing conflicts and ensuring proper traffic routing.
4 Deploy and Configure Gateways
Ensure Gateways are deployed to handle traffic securely and efficiently for each device type.
5 Monitor and Adjust
Use monitoring tools to track performance and adjust policies as needed to maintain security and optimize network efficiency.
Benefits and Outcomes
