What STI does

STI Ltd is a privately-held defense and homeland security technology company that develops and manufactures specialized electronic detection and inspection systems for government, civil, para-military, and policing forces. The company's product portfolio comprises four core systems: the TI-S Series under-vehicle inspection system (optical scanning of vehicle undercarriages with multi-angle camera head and optional LPR integration), the SN Series gas-chromatography vapor explosives detector with electron-capture technology and PPT-level sensitivity, the RWA System for real-time monitoring of prohibited chemicals in running water and reservoirs, and the MIAD System for maritime container inspection with multi-sensor and big-data cross-referencing against documentation.

STI operates an enterprise field-sales motion targeting government offices, embassies, border checkpoints, correctional facilities, airports, power plants, oil and gas refineries, and sporting/convention events worldwide. Revenue is generated predominantly through one-time hardware sales under quote-based government procurement, with the product philosophy emphasizing short time-to-market development cycles, in-house design and manufacturing, and ISO 9001:2015-compliant components backed by US and international patents. Customer pricing is not publicly disclosed.

Following an agreement to be acquired by Swedish electronics manufacturing services firm NOTE in 2025-2026 for approximately GBP 72.5 million enterprise value at ~6x EV/EBITDA, STI has secured SEK 900 million in acquisition financing from SEB and is positioned to scale toward GBP 60 million in projected 2026 revenue at 9.5-10.5% operating margins. Concurrent with the acquisition, STI entered a distribution partnership with KeepZone AI Inc. to deploy AI-powered security solutions across the 2026 FIFA World Cup in Canada, Mexico, and the United States, extending its historical EMEA footprint into North American mass-event security.

Products and services

• TI-S Series Under Vehicle Inspection System Automated undercarriage inspection system for detecting irregular objects such as explosives, drugs, contraband, and smuggled persons on vehicles. Features a 4-axis optical head unit with high-resolution camera, automatic and manual scan modes, 36x optical autofocus zoom, and remote operation capability for bomb squad technicians. Optional integration with License Plate Recognition (LPR) systems for documentation and investigation.
• SN Series GC Detection System Handheld and desktop vapor explosives detector using proprietary gas chromatograph technology with selective pre-concentration and electron capture detection. Detects standard commercial, military, and improvised explosive compounds at parts-per-trillion (PPT) levels without false alarms on common substances.
• RWA System (Running Water Analysis) Real-time water monitoring system using proprietary modified purge and trap-GC technology to detect prohibited chemical concentrations, contaminants, poisons, and hazardous materials in running water, reservoirs, and lakes. Features automatic data calibration, real-time alerts, and active I/O abilities for industrial factories and water authorities.
• MIAD System (Maritime Intelligence Analysis & Detection) Multi-sensor solution with flexible operational software (big data) for efficient maritime container inspection during loading and unloading. Integrates data from various sensors and compares container documentation against physical measurements including length, weight, color, seal presence, ID, hazardous materials, and radiation. Open platform supporting unlimited sensors with configurable smart alarms for port security and customs personnel.

Direct peers

• Nuctech: Nuctech is a global security inspection equipment manufacturer with overlapping product lines in cargo/vehicle screening, container inspection, and explosives detection — directly mirroring STI's TI-S, SN, and MIAD portfolios across the same government and border-security customer base.
• Smiths Detection: Smiths Detection is a global leader in threat detection and screening technologies including GC-based vapor explosives detection, trace detectors, and checkpoint inspection — its IONSCAN and similar GC platforms are the most direct functional competitor to STI's SN Series.
• Rapiscan Systems (OSI Systems): Rapiscan provides cargo, vehicle, and people screening systems for aviation, border, and critical-infrastructure security — overlapping STI's TI-S under-vehicle inspection and MIAD maritime cargo inspection segments with direct go-to-market competition.
• Astrophysics Inc. Astrophysics manufactures X-ray-based under-vehicle inspection systems, mobile cargo inspection, and detection equipment — directly comparable to STI's TI-S UVIS for the same checkpoint, embassy, and high-security-facility use cases.
• Gatekeeper Security: Gatekeeper Security specializes in under-vehicle inspection systems (UVIS), automatic number plate recognition, and intrusion detection for military, embassy, and critical-infrastructure customers — the closest head-to-head rival in STI's flagship TI-S UVIS product category.
• Bruker Detection: Bruker Detection produces chemical and explosives trace-detection systems, ion-mobility spectrometers, and CBRNE identification equipment for defense, aviation security, and border protection — direct competition for STI's SN Series GC vapor detection and adjacent threat-detection use cases.

Broad incumbents

• Thales Group: Thales is a large established defense, aerospace, and security group with broad screening, border-security, and CBRNE-detection product lines within its portfolio — overlapping STI's markets via larger enterprise contracts rather than niche specialization.
• L3Harris Technologies: L3Harris is a major U.S. defense prime with a security and detection portfolio covering cargo inspection, radiation detection, and integrated screening for ports and borders — competing with STI in maritime/container inspection and broader HLS procurement.
