What Interface Systems does

Interface Systems (Interface Systems LLC) is a privately held managed security and network services provider headquartered in St. Louis, Missouri, founded in 1995. The company delivers an integrated platform combining AI-powered remote video monitoring, managed intrusion and access control, fire alarm monitoring, video intelligence, and managed network/voice services (SD-WAN, SASE, firewall, WiFi, VoIP, PCI compliance) to multi-location enterprises. Its operations are anchored by US-based, UL-Listed, TMA Five Diamond Certified Interactive Security Operations Centers (iSOCs) that combine autonomous AI detection with live human intervention specialists who can see, hear, and speak with people at monitored locations in real time. The platform is differentiated from passive CCTV by this active deterrence model, exemplified by products such as Virtual Perimeter Guard, Virtual Security Guard, Video Verified Alarm, and proprietary alarm-panel monitoring technologies including TamperShield and JamAlert.

The company serves more than 50,000 customer locations across primary verticals of multi-location restaurants, multi-location retail, and car wash operators, with secondary reach into commercial businesses, hospitality, and financial services. Notable enterprise customers include Panda Express (1,960+ locations), WKS Restaurant Group (394 restaurants), MOD Pizza (420+ locations), White Castle, Big Brand Tire & Service, El Pollo Loco, Mister Car Wash, AutoZone, Sally Beauty, Williams Sonoma, The Container Store, Dollar General, GameStop, and Edward Jones. Pricing is quote-based, sold primarily through direct enterprise field sales with consultative security assessments, solution engineering scoping, and a 60-Day Proof pilot. Revenue is predominantly recurring subscription and managed services, supported by professional services for installation and a hardware component for Virtual Perimeter Guard units.

Interface is backed by institutional capital from Prudential Capital Partners, Bregal Sagemount, and Everberg Capital, with disclosed financings totaling approximately $200 million across 2009, 2017, and 2021. The company is founder/owner-operated with a full C-suite including CEO Brent Duncan, Executive Chairman Michael T Shaw, CTO Brian Garavuso, CFO Ken Obermeyer, and COO Bud Homeyer. Operating geographies are US-only with 12+ office and distribution locations supporting nationwide field service coverage. The company does not appear to be venture-backed and shows no evidence of imminent IPO or M&A activity in the source materials.

Scale indicators22 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• ADT (now Securitas): Largest US commercial and residential monitored security provider. Directly comparable to Interface on managed intrusion, video monitoring, and access control, but ADT/Securitas serves a much broader customer base including residential, whereas Interface focuses exclusively on multi-location commercial enterprises.
• Stanley Security (Securitas Technology): Global commercial security integrator offering monitored video, intrusion, access control, and fire services. Comparable to Interface across all four pillars (video, alarms, network, voice) but operates at a larger global scale with broader enterprise/government reach.
• Convergint Technologies: Large global security, fire, and life-safety systems integrator. Comparable to Interface on integration depth across video, access, and fire, but Convergint skews to larger enterprise/government projects rather than recurring monthly monitoring of SMB multi-location brands.
• Allied Universal (Helmsman): Largest US security services provider, combining manned guarding with electronic security and monitoring. Comparable in offering managed monitored security services (including through its Helmsman-branded division) but anchored by a physical guard services model.

Direct peers

• Sonitrol: Pioneer of audio-verified intrusion detection and central station monitoring. Interface actually maintains a Sonitrol Support line, suggesting an operating or acquired relationship. Directly comparable on verified-alarm monitoring and central-station intervention for commercial accounts.
• Vector Security: US-based managed security provider serving multi-location commercial and residential customers with monitored intrusion, video, access control, and fire. Closely comparable in vertical mix (retail, restaurant, commercial) and managed-services delivery model.
• Stealth Monitoring: North American leader in live video monitoring with proactive video surveillance and intervention specialists. Directly competes with Interface's Remote Video Monitoring and Virtual Perimeter Guard offerings for multi-location commercial and retail customers.
• Pro-Vigil (formerly ECAM): Provider of remote video monitoring services with AI-augmented detection and live intervention. Directly competes with Interface's Virtual Perimeter Guard and Virtual Security Guard on the same multi-location enterprise go-to-market.
• Radius Security: Canadian-based live video monitoring and interactive security operations provider. Highly comparable service offering and target customer mix, with primary geographic presence in Canada and US Pacific Northwest — adjacent but not directly overlapping territory with Interface.
• Kastle Systems: Managed access control and video provider focused on commercial office and multi-tenant real estate. Comparable on managed access and integrated video, but Kastle's vertical focus is office buildings rather than restaurants/retail where Interface concentrates.
