Surroundings & Perimeter Monitoring
See what happens around your facilities, and act on it.
Physical security is the first layer of cybersecurity. We design monitoring for your facilities and surroundings: camera placement, intrusion and environmental sensors, access control integration and alerting that turns raw footage into decisions.
Who this is for
Built for organizations like yours
Warehouses & Industrial Sites
Large perimeters, yards and loading docks where incidents happen out of sight.
Offices & Campuses
Multiple entrances, visitors and shared spaces that need consistent coverage.
Critical Infrastructure
Data rooms, utilities and equipment where physical access means total compromise.
The problem
Risks we address
Blind spots
Cameras installed years ago that miss entrances, fence lines and the places incidents actually occur.
Footage nobody watches
Recordings reviewed only after the fact, when real-time alerts could have stopped the incident.
Insecure cameras and recorders
Default passwords and outdated firmware that make the security system itself an entry point to your network.

Walk your sites and review existing systems, incidents and risks.

Why Thornshield
Why work with us
Digital and Physical
One partner for compliance, cybersecurity and the physical security technology that protects your sites.
Policy to Practice
Policies are only useful when controls enforce them. We design both, so audits reflect reality.

Recommendations are based on your risk and budget, not on a product we need to sell.
Engineers Who Build
When commercial tools fall short, we write the software ourselves, securely.
FAQ
Common questions
Do you install the cameras?
We design, specify and integrate the system and work alongside licensed low-voltage installers for physical installation. That keeps recommendations vendor-neutral.
Can you work with our existing cameras?
Yes. Many existing systems can be secured, re-aimed and connected to analytics and alerting without full replacement.
