How Governed Are Your Cellular OT Devices, Really?
A 5-section assessment for security leaders responsible for cellular-connected OT device risk. Answer questions about your current visibility and controls — we'll benchmark your maturity and flag your most urgent security gap. Select the option that most accurately describes your current state, not your aspirational state.

These questions won't affect your score — they help us tailor your results and benchmark you against similar organizations.
Question 1 of 3
What is your primary role in the organization?
Question 2 of 3
What best describes your organization's primary cellular network architecture for OT and IoT devices?
Question 3 of 3
Which best describes your current OT security program's coverage of cellular-connected devices?
Section 1 of 5
Section 01 of 04 · Device and SIM Visibility
Can you actually see everything connected to your network?
You can't defend what you can't see. This section checks how deep your device visibility goes — and whether restricted manufacturers are being tracked.
Question 1 of 3
Are you able to identify the make, model, manufacturer, and firmware version of every device connected to your cellular network, including devices behind routers or gateways?
Question 2 of 3
How do you identify devices that are connected to your cellular network but were not formally onboarded through your standard procurement process?
Question 3 of 3
How does your organization address devices from manufacturers flagged by government advisories, such as FCC-restricted manufacturers or NDAA Section 889 prohibitions?
Section 02 of 04 · Authentication, Access Control, and Zero Trust
Could a rogue device get onto your network undetected?
Device identity, segmentation, and integration with your broader security stack determine whether an unauthorized device is caught in minutes or never.
Question 1 of 4
How does your cellular network authenticate devices before granting them access?
Question 2 of 4
If a SIM were removed from an authorized device and placed into unauthorized hardware, would your security systems detect this?
Question 3 of 4
Do you have policy controls that restrict which cellular-connected devices can communicate with specific systems or segments of your OT network?
Question 4 of 4
How are your existing security tools, including firewalls, NAC, and SIEM, informed about cellular-connected devices on your network?
Section 03 of 04 · Threat Awareness and Compliance Readiness
If a device type were compromised today, how fast could you respond?
State-sponsored actors like Salt Typhoon and Volt Typhoon have proven that cellular OT infrastructure is an active target. This section checks your awareness and response speed.
Question 1 of 4
How familiar is your organization with the Salt Typhoon and Volt Typhoon threat campaigns and their relevance to cellular OT environments?
Question 2 of 4
How does your organization address regulatory compliance requirements that apply to cellular-connected OT devices, such as NERC CIP, IEC 62443, or TSA cybersecurity directives?
Question 3 of 4
Do you have continuous monitoring of whether each cellular device is operating within its intended network segment, with alerts when it deviates?
Question 4 of 4
If a specific device type or manufacturer were identified as compromised, how quickly could your team find every affected device and restrict its network access?
Section 04 of 04 · Program Maturity and Organizational Readiness
Who actually owns this risk today?
The final section looks at organizational visibility, and asks you directly where you feel the biggest gap is.
Question 1 of 3
Which stakeholders in your organization currently have visibility into the security posture of your cellular-connected device fleet?
Question 2 of 3
How integrated is your cellular device security with your broader OT security program, including SIEM monitoring, SOC coverage, and incident response workflows?
Question 3 of 3 (Select all that apply)
What is your organization's greatest current gap in managing the security of cellular-connected OT devices?
