What SOS Security LLC does
SOS Security LLC is a privately-held U.S. contract security services provider headquartered in Parsippany, New Jersey. Founded in 1969 by Edward B. Silverman — who continues to serve as Chairman and CEO — the firm has grown into one of the largest privately-owned security companies in the United States, employing between 5,001 and 10,000 people. The company operates in the manned guarding and security services sector, serving enterprise and institutional clients across multiple states.
The business model is built on long-term recurring service contracts for security personnel, supported by a distributed branch and licensing footprint required to operate nationally. Revenue mechanics are typical of the contract guarding industry — subscription-style multi-year service agreements, quote-based pricing tailored to site requirements, and recurring monthly billing. The product surface spans uniformed security officers, specialized training, and protective services, with the operational complexity scaled through a national workforce and a dedicated training organization led by a Chief Learning Officer.
Growth has been pursued both organically and through acquisition. SOS Security acquired New Horizon Security Services in January 2017 and Global Protection Management in July 2019, extending its customer base and geographic reach. The senior leadership team — including a CFO, General Counsel, Chief Security Officer, and Chief of Staff — signals an organizational maturity oriented toward compliance-heavy, multi-jurisdictional service delivery.

SOS Security LLC competitors and assessment
Company assessmentDirect peers
- Allied Universal: The largest US private manned guarding and integrated security services provider, operating ~150,000+ personnel across North America. Directly comparable to SOS Security on core offering (security guards, patrol, government services) and target customer base, but materially larger and with a proprietary technology stack.
- GardaWorld: Privately-held global security services firm headquartered in Montreal, with significant US cash-services and guarding operations. A comparable privately-held peer in the manned guarding and cash-handling markets with similar scale dynamics and acquisition-led growth model.
- Brink's: Publicly-listed US-headquartered cash management, secure logistics and digital retail solutions provider with substantial security guarding and electronic monitoring lines. Comparable on cash inventory management, electronic monitoring and physical guarding for retail/financial customers.
- St. Moritz Security Services: US privately-held security guarding and security consulting firm serving commercial, industrial and government customers. Comparable in scale and service mix to SOS Security, including unarmed/officers, security consulting and uniformed services.
- Covenant Security Services: US-based privately-held security services company providing manned guarding, executive protection and security consulting. Directly comparable in service mix and target customer base for SOS Security.
- National Security & Protective Services: Smaller US privately-held guarding and protective services provider serving commercial, residential and government accounts. Relevant competitor for the same mid-market and regional accounts that SOS Security serves.
- AP Security Group (APG): US privately-held security services company specializing in security officers, concierge/security services and uniformed guarding across multiple industries. Closely comparable to SOS Security on offering, customer base and scale tier.
Broad incumbents
- Securitas AB: Publicly-listed Swedish-origin global guarding and integrated security services leader operating in ~44 markets. A broad incumbent overlap on guarding and security systems, but with materially greater international and technology-services diversification than SOS Security.
- Prosegur: Spain-headquartered global security and cash logistics group with operations across the Americas including the US. Comparable on guarding and armored cash services, though broader across Latin America and Europe than SOS Security's US-only footprint.
- ISS A/S: Denmark-headquartered global facility services provider whose integrated facility management (IFM) overlay includes security, reception and concierge services. Comparable as a broad incumbent that competes with mid-sized US guarding providers for combined facility-and-security contracts.
