Security Businesses for Sale
Whether it's cybersecurity, physical security services, or security hardware, the acquisitions that generate the most interest have one thing in common: recurring contracts clients can't easily walk away from and a credentialed team that runs independently.

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.

FAQ
Security Business Acquisition
What should I look for when buying a security business?
Start by asking the seller to break out recurring contract revenue from one-time installation or project work. Then understand who holds the key credentials: security clearances, low-voltage licenses, and software certifications. Review the contract list with renewal dates and transfer language. Finally, assess how much the business runs without the owner. Browse security businesses for sale on Rejigg to see how sellers in this space present their financials and contracts.
How much does a security business cost?
Security businesses typically sell for 3 to 10 times annual profit depending on how much revenue is under contract, the depth of the team's credentials, and whether operations run independently. Businesses with a cleared workforce and long-term government contracts can reach the higher end. Owner-operated companies relying primarily on installation projects tend to sell in the 3 to 5x range. Use the SBA loan calculator to model what monthly payments might look like.
How do I evaluate a security business before buying?
Ask the seller to separate recurring service and monitoring revenue from installation and project work. Review the contract list with renewal dates, renewal history, and any transfer language. Get a full picture of who holds licenses and clearances and whether those individuals plan to stay. For physical security and technology companies, ask what percentage of clients have installed equipment and what renewal rates look like on service agreements. For cybersecurity, understand what portion of revenue is locked in on multi-year agreements.
What due diligence questions should I ask about a security business?
Good questions to start with: What percentage of revenue is under recurring contract versus one-time project work? What are the renewal rates on service and monitoring agreements? Which team members hold professional licenses, certifications, or clearances, and what is their tenure? Do government contracts transfer when ownership changes, and has that been confirmed with the contracting agency? Is installed equipment owned or leased, and what does maintenance on that equipment look like? These questions help you understand the real durability of the income before you're committed.

How do security clearances affect a business acquisition?
Security clearances are one of the most valuable and least replaceable assets in a security company. They take years to obtain, can't be transferred between companies, and are tied to individuals, not the business entity. When evaluating a security company with a cleared workforce, find out each team member's clearance level, whether those employees are under employment agreements, and what transition plans look like. Facility clearances require their own formal process when ownership changes. Starting that process early is critical for government-focused deals.
How does installed equipment affect the value of a security technology or physical security business?
Installed hardware is one of the strongest retention drivers in the security category. Cameras, access control panels, and alarm systems that are physically wired into a client's building create real switching costs because replacing them would mean ripping out infrastructure and interrupting operations. Buyers get excited about this because it means service agreement renewals happen naturally without anyone having to re-sell the client. Ask what percentage of clients have installed equipment and what the renewal rate on service agreements covering those systems looks like.
