What Security Industry Specialists does
Security Industry Specialists, Inc. (SIS) is a privately held, founder-owned boutique security services firm founded in July 1999 in California by John Spesak, a former law enforcement officer. Headquartered at 6071 Bristol Pkwy in Culver City with a stated presence in Miami Beach, SIS employs 5,001–10,000 people and serves Fortune 500 corporations, designer brands, celebrities, and high-profile executives across the technology, entertainment, and consumer-product industries. Apple has been a client since the firm's founding, and the current roster also includes Salesforce, Airbnb, Microsoft, OpenAI, Zoox, and the San Francisco Giants.
The company's service portfolio spans seven integrated lines: Core Security Operations (on-site programs for offices, campuses, labs, distribution centers, and data centers), Executive Protection, Retail Security, Intel Services, Custom Training, Site Assessments, and Secure Logistics. These are supported by a 24/7/365 Fusion Center staffed by Intel analysts and SOC professionals, which delivers ad-hoc support, real-time risk assessments, and client-specific Security Operations Centers, complemented by proprietary emergency-notification tools and real-time tracking technology. Training capacity exceeds 1,000 courses across technical, specialized, and soft-skill formats, and the firm hires from approximately the top 5% of applicants (3,307 hires from 93,871 applicants in the most recent year), yielding record-low turnover.
Commercially, SIS operates a managed-services and professional-services revenue model with quote-based enterprise pricing and transparent, personalized invoicing; published hourly rates for entry-level security specialists range $19–$25 per hour. The go-to-market is deliberately boutique and word-of-mouth driven, with direct enterprise sales and a website contact form replacing channel-based distribution. Geographic reach spans North, South, and Central America through offices in Austin, New York, San Jose, Seattle, São Paulo (LATAM regional HQ), Rio de Janeiro, and Mexico City. SIS also intermediates San Francisco's Section 10B private security program, arranging dedicated police-officer coverage for corporate clients, with billings to individual clients exceeding $1M annually for that single program.

Security Industry Specialists competitors and assessment
Company assessmentBroad incumbents
- Allied Universal: Largest U.S. physical security services provider offering manned guarding, electronic security, and security systems integration. Directly comparable to SIS as a Fortune 500 enterprise security vendor but with significantly broader scale, geographic reach, and a PE-backed roll-up strategy.
- Securitas: Global security services giant providing manned guarding, mobile patrol, and electronic security for enterprise clients. Comparable to SIS across on-site guarding and SOC offerings but with vastly larger global footprint and a publicly traded scale advantage.
- GardaWorld: Canadian-based, privately held global security and cash services company. Comparable to SIS in physical security services and enterprise client focus, with comparable cash-in-transit/secure logistics overlap and similar PE-driven growth posture.
- Prosegur: Spanish global security firm with strong LATAM presence providing manned guarding, cash logistics, and security technology. Comparable to SIS given Prosegur's overlap in retail security, secure logistics, and Americas/LATAM footprint.
Direct peers
- Constellis: U.S.-based security services provider offering executive protection, corporate security, and protective services for Fortune 500 and high-profile clients. Closest direct peer to SIS's boutique model with similar executive protection and high-profile client focus.
- Stallion Security: Boutique U.S. security services provider focused on Fortune 500 enterprise clients with on-site guarding, executive protection, and security consulting. Comparable to SIS as a boutique alternative to scaled incumbents.
- Global Security Concepts: Mid-sized U.S. security services firm providing on-site security, executive protection, and event security to corporate and high-profile clients. Directly comparable to SIS in service portfolio and boutique positioning.
- Brink's: Global secure logistics and cash management company with a small manned-security arm. Comparable to SIS's Secure Logistics offering and real-time tracking technology for confidential material transport.
- Loomis: Global cash-in-transit and secure logistics provider with operations across the Americas and Europe. Overlaps with SIS's Secure Logistics service line and shares similar real-time tracking technology requirements.
Emerging players
- ADT: Publicly traded security systems provider specializing in intrusion detection, video surveillance, and monitored security for commercial and residential customers. Partially comparable to SIS's electronic security/SOC capabilities but more technology-focused rather than manned guarding.
