How this Security Systems data is built

Serava continuously maps 35,516 security systems businesses across 10 states and provinces, sourced from public registries, licensing boards, and corporate filings. Every company is real and currently operating, not a recycled broker listing.

Each business is scored 0 to 100 on the signals that predict a quiet, off-market sale: owner tenure, succession indicators, business age, and contact reachability. The result is a ranked shortlist of owner-led companies that are not posted on any marketplace.

Coverage is refreshed continuously and re-verified against source records. The counts shown reflect deliverable, owner-led targets in each market, not raw directory totals, so what you see is what we can actually hand you.

Built and maintained by Serava, an off-market acquisition sourcing platform, with sourcing methodology overseen by founder Sadra Khorvash. Last updated September 2026.
