An Operating System
for Protective Services.
To your client, this is your app.
Your client opens an app that carries your firm's name and logo — not ours. They see the operations you run, the intelligence you deliver, and the activity on their account, as it happens. Arbiter stays in the background by design.
Quiet months stop looking like idle months.
Between incidents, your client watches the standing work land — monitoring reports, assessments, the record of who's touched their file. And when they need more, they ask in a few taps. The request hits your queue scoped and ready to price.
A retainer the client can open is a retainer that renews.
Person dossiers drawn from dozens of cited public sources — courts, corporate filings, public records, media — structured the way an analyst would build them.
Mission briefs and AARs draft themselves from the operation — the site, the attachments, the voice notes your team captured in the field.
Walk the site and capture photos and voice notes. The write-up comes back as a structured threat & vulnerability assessment for your assessor to sign.
AI does the drafting. Your people review and sign everything before a client sees it.
Holds what it must. Can't read what it shouldn't. Forgets on command.
Client identities, movements, site intelligence, after-action detail — the most sensitive data your clients have lives with whoever protects them. Arbiter is built so that data is hard to reach, harder to leak, and gone when you say so.
Your contractor sees his op — not your client book. Change an assignment and what they can see changes that instant, everywhere. Nothing goes stale in a tool you forgot about.
Every room is end-to-end encrypted with keys that live on your devices. We relay ciphertext. There is no copy for us to leak, lose, or hand over.
Every file open, export, and screenshot is on the record — your team's, the client's, and the AI's, labeled as such. Exported PDFs carry a forensic mark tied to whoever pulled them.
Your CSO will want the details. We wrote them down.




Every firm on Arbiter is verified before it goes live — legal entity, owners, licenses, insurance, screened against sanctions lists. Arbiter serves licensed professionals only.
Add your team and set roles — operators see their assignments, managers see the book. Set your service types and pricing.
Send your client a single link. They sign up in minutes, land in your branded app, and you activate the engagement.
Requests come in scoped. Briefs, dossiers, and after-actions draft themselves for your review. Your client watches the work land — and every operation deepens what the platform knows for the next one.
Built by the people who do the work.
Arbiter is built by Arbiter Defense Group — a team of special operations, combat arms, and law enforcement veterans who got tired of running complex security operations on spreadsheets and group threads. We built the platform we wanted to use. Now we put it in the hands of firms that run the same way.
We'll walk you through the platform and show you what it looks like with your clients on it.
