Due diligence
What to Look For
Practical guidance from hundreds of real acquisition conversations.
Recurring vs. Project Revenue
- Ask for a revenue breakdown separating monitoring contracts, managed security service agreements, annual software subscriptions, and maintenance agreements from one-time installation and project work.
- The contracted, repeating income is what drives premium valuations — project work matters too, but it has to be re-won each cycle.
- Monitoring contracts and managed service agreements that renew without re-selling are the single most important revenue quality signal across all security sub-categories.
Credentials and Clearances
- Understanding exactly who holds which credentials and whether those people plan to stay is one of the most important due diligence questions in this category.
- Security clearances, particularly high-level ones, take years to obtain and cannot be quickly rebuilt after a sale.
- Low-voltage licenses, manufacturer certifications, and CISSP or similar credentials are genuine competitive advantages that transfer with the people who hold them.
Contract Depth and Transfer
- Ask to see the contract list with expiration dates, renewal history, and what each agreement says about ownership transfers.
- Long-term contracts — whether multi-year government agreements, commercial service agreements, or monitoring subscriptions with auto-renew — separate a company with stable income from one riding on project volume.
- Government contracts require additional care, since some require formal approval or re-certification when ownership changes.
Equipment and Integration Stickiness
- Ask what percentage of clients have installed equipment and what the renewal rates look like on service and monitoring agreements covering those systems.
- In physical security and security technology, installed equipment creates a loyalty effect buyers can get genuinely excited about — cameras, access control panels, and intrusion systems wired into a building are expensive and disruptive to replace.
- When clients have your hardware in their walls and your software in their workflows, they tend to stay.
Team and Operations Independence
- Ask who handles each major client relationship and what happens to operations if the owner steps away for a month.
- The best security acquisitions run without the owner dispatching every job — whether it's a security operations center staffed around the clock, a dispatcher routing technicians independently, or an operations manager who handles installs and client calls without the founder.
- Management depth is what makes a security business truly transferable.

Security businesses land across a wide range because the difference between a company with a cleared team and multi-year government contracts versus one dependent on one-off installation projects is enormous from a risk and cash flow standpoint.
