We built and operate Perimeter OS, a multi-tenant SaaS for security companies. Use the platform — or have us build a system shaped around your contracts.
Two paths
Most software vendors selling to security companies have never run guard operations software in production. We have: Perimeter OS is a guard management platform we built from scratch and operate — patrol and QR checkpoint scan windows, officer scheduling, a client portal, CRM & billing, and compliance monitoring in one dashboard. That gives you two ways to work with us.
A ready-made, multi-tenant guard management SaaS — patrol & QR checkpoint scan windows, scheduling, client portal, CRM & billing, and compliance monitoring. If your operation fits, it's the fastest way to get running.
For security firms whose workflow doesn't fit off-the-shelf — unusual contract requirements, specialized reporting, or operations no subscription product models. We build it around how you actually run posts.
What you get
Built to your post orders, your client contracts, and your compliance obligations — and you own the code, the data, and the server.
Guards scan checkpoints to prove tour compliance — timestamped, location-tied, and impossible to pencil-whip. Missed scans surface immediately.
Post assignments, shifts, and coverage in one view — so supervisors know who's where, and open posts get caught before the client calls.
Give property managers and clients their own login to see patrol activity and reports in real time — proof of service without the weekly email thread.
Structured DARs and incident reports guards can file from a phone — searchable, exportable, and attached to the site and shift where they happened.
Turn scheduled hours and contracts into invoices without re-keying — so what you billed matches what you actually staffed.
Dedicated fire watch patrol logging for sites that require it — compliant records your clients and inspectors can rely on.

FAQ
Start with the platform. A Perimeter OS demo will tell you quickly whether it fits your operation — patrol compliance, scheduling, client portal, and billing cover what most guard companies need. Go custom when your contracts demand workflows no off-the-shelf product models: unusual reporting obligations, specialized compliance, or operations that don't fit the standard mold. We'll give you a straight answer on the first call.
We built and operate a guard management platform used in production — so tour compliance, post orders, DARs, fire watch logs, and client reporting aren't abstractions to us. When you describe how your posts run, you won't be teaching your software vendor the industry from scratch.
You do — the code, the data, and the server, documented and in your name from day one. Keep us on for managed hosting and support (from $200/mo), or hand everything to your own team.
