A guard company runs on paper that nobody outside the industry ever sees. Post orders tell each officer what to check and who to call, daily activity reports log every round, and an incident report turns a 2am door alarm or a fight in a parking garage into a written account a client and an insurer will read. On the alarm side, a monitoring center logs every signal, the operator's verification call, the keyholder list worked through and the decision to dispatch or cancel, while installers and service techs leave work orders behind each panel and camera they touch.
That is procedure followed and judged thousands of times, and micro1, for one, asks for exactly that kind of repeated workflow. Polyshares names Security and alarm on its intake and asks for recorded calls, Ventra lists staffing and call centers among the industries labs buy from, and Nyne names tickets, dispatch and calendars. No buyer we track has published a security company deal yet.
What makes this industry different is what must stay home: alarm codes, site floor plans, camera footage and anything that would help someone get past a client's defenses. In our reading, post orders, training material and incident narratives with names stripped are the safer place to start. Take the quiz to see which buyers take a company with your headcount.

What buyers value
What in a company's records buyers value
What buyers look for in your records, and what to talk through with your buyer before anything leaves your systems.
| Data | Where it lives | Why a buyer values it | Raise with the buyer |
|---|---|---|---|
| Daily activity and incident reports | Guard management apps (TrackTik, Silvertrac) or Word and PDF reports | Written accounts of what an officer saw, did and escalated, in a fixed format across thousands of shifts. | Names of victims, suspects and witnesses, and police report numbers. |
| Post orders and site procedures | Shared drive or the guard app's document library | The rules each officer works from, site by site, and the clearest record of the company's own method. | Site layouts, access points and anything a client would treat as a security plan. |
| Monitoring center event and operator logs | Central station automation software | Signal, verification, call list and outcome for every alarm, a decision trail with a time stamp on each step. | Subscriber names, addresses and passcodes inside the account notes. |
| Operator and dispatch call recordings | Phone system at the central station | Real conversations with homeowners, keyholders and police dispatch, under pressure and on a script. | Whether every party heard a recording notice. |
| Install and service work orders | Field service or alarm dealer software | Site surveys, equipment lists and the fix for each trouble signal, the technical side of the business. | Nothing specific |
| Scheduling and shift coverage records | Scheduling module, email and text threads | How a callout at 10pm gets covered, overtime gets approved and a post never goes empty. | Officer personal details, license numbers and pay rates. |
A week of records
A week of data at a company
- Monday: officers at each post file activity reports for the weekend, and any incidents are written up for the client.
- Tuesday: the monitoring center works a storm night of low battery and power fail signals, most cancelled by phone.
- Wednesday: an installer files a site survey and proposal for a warehouse camera system.
- Thursday: a client emails a complaint about a missed round, and the supervisor's reply cites the patrol scan log.
- Friday: the scheduler fills weekend gaps by text and the training lead updates a post order after a site change.
Process
How it works with each buyer
In each buyer's own words. Where a buyer publishes nothing, we say so.

In our reading, guard companies and alarm dealers are bought mostly for their client contracts and monitored accounts. When accounts or a guard book change hands, the written record behind them is a different set of records, and whether a copy could be offered before the sale is a question to talk through with the buyer you're working with. Pewter takes companies that are operating, winding down or closed with 20+ people now or at their peak, and micro1's ads ask for closed companies that had 25+ employees at their peak.3,4
FAQ
Security guard and alarm companies: questions, answered
Polyshares lists Security and alarm on its intake, and in our reading the written record is what counts: daily activity reports, incident reports and post orders. We have found no published deal for a security company, so the price is set once a buyer sees your records.1
Yes. Security guards score 83 out of 100 on O*NET's email scale and their supervisors 98, so this is a writing job more than most people think. Ask the buyer which export format it takes from your guard app, whether text or PDF.2
Every business is different, so this one is best talked through with the buyer you're working with. Their team goes over it with you before anything is signed.
