Best Physical Security Services Companies in United States
The 1734 best Physical Security Services companies in United States in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Allied Universal.
Ranking the best Physical Security Services companies in the United States by disclosed equity funding and recent momentum, this directory tracks 1,734 firms with a combined $769M in disclosed capital. No unicorns yet, but the spread is wide. Allied Universal sits at the top with $600M raised, and the distance between that and Vsblty's $18M or Sentryinteractive's $11M tells you something real about how concentrated funding is here.
The sector's revenue picture is honestly mixed. Across eight filers, the median sits at $18M, but combined they pool roughly $3.5B, which means a few giants are carrying serious weight. Aes Corp alone logs $3.2B, that's 172x the sector median, while Monitronics International's $162M comes with a -70% YoY revenue drop that's hard to ignore. Median revenue growth across filers is -36% YoY, so contraction is real for most players. What's countering that? App-layer momentum: median install growth is running +19% YoY across 403 security-adjacent apps, and SIA's research on regional physical security markets signals that demand is shifting geographically too. Geopolitical themes, national security strategy, and multilateral diplomacy are driving new contract cycles, which means if you're evaluating vendors right now, funding trajectory matters as much as revenue history.
