What Redline Assured Security does

Redline Assured Security Limited is a UK-headquartered provider of aviation security training, consulting and quality assurance services, founded in 2006 by Paul Mason in Doncaster. It operates from two principal training centres — the National Safety and Security Academy (NSSA) at Doncaster Sheffield Airport, which holds ICAO Aviation Security Training Centre (ASTC) endorsement (one of approximately 35 worldwide), and a Bracknell facility for counter-terrorism training. Redline serves airports, airlines, ground handlers, regulators, critical national infrastructure operators, event venues, rail, and maritime clients, delivering Government-standard security solutions in regulated and high-threat environments. The company has been acquired twice: by Air Partner plc in December 2019 and then by TrustFlight Limited in August 2025, where it sits alongside Baines Simmons and Kenyon Emergency Services within an integrated aviation services group serving roughly 1,600 aviation organisations globally.

The company's product and service portfolio combines proprietary cloud-based software with instructor-led and eLearning training, plus consulting. Core software products include the Threat Image Recognition Training (TIRT) platform — available in 2D X-ray and 3D CT variants with six levels of threat complexity and automated performance reporting — and the Security Management System (SeMS) digital platform with tablet-based real-time data capture, automated reports and risk matrices. Training courses span Aviation Security Manager (ASM), Recognition of Firearms and Explosives (RFX) Instructor, Threat Assessor (TA), General Security Awareness Training (GSAT), Behaviour Detection Awareness, and the SFJ Awards Level 3 Counter-Terrorism Protective Security and Preparedness (CTPSaP) qualification aligned to Martyn's Law. Consulting services include auditing, inspections, covert quality assurance testing, FREDDs certification (under a CAA contract), and document authorship such as Aircraft Operator Security Programmes.

Redline makes money through four revenue streams: instructor-led and eLearning training delivery (professional services), SaaS-based TIRT and SeMS subscriptions, consulting and assured services (auditing, FREDDs certification, quality assurance, regulated site listing), and managed services (embedded security personnel, training management, compliance management, bespoke content). The customer mix is dominated by enterprise and government buyers procured through enterprise field sales, supplemented by event-driven demand generation at industry expos such as International Security Expo. Pricing is largely quote-based with bespoke enterprise proposals, although select eLearning courses have published per-seat pricing. The company was previously privately held; it is now a wholly-owned subsidiary of TrustFlight Limited following the August 2025 acquisition from Wheels Up, with founder Paul Mason continuing as Managing Director.

Direct peers

• Baines Simmons: Sister company within TrustFlight following the August 2025 acquisition. Provides aviation safety, human factors and compliance training/c consultancy to operators, MROs and regulators. Highly comparable as a regulated aviation training specialist now operating under the same parent platform.
• ICTS Europe: Global aviation security services provider offering passenger and baggage screening, document verification, and security training to airlines and airports. Direct competitor to Redline's aviation security training, SeMS and quality assurance offering across European and international airports.
• Kenyon Emergency Services: Sister company within TrustFlight following the August 2025 acquisition. Provides emergency response, repatriation and mortuary services for aviation and mass-casualty incidents. Comparable as a TrustFlight group aviation-services peer rather than a direct training competitor.
• Aviation Security Services Limited: UK-based provider of aviation security training, guarding and consulting services to airports, airlines and handlers. A direct domestic peer overlapping with Redline across AVSEC training courses and screening operations support in the UK market.

Broad incumbents

• IATA (International Air Transport Association): Industry association that sets training standards (e.g., AVSEC), operates the ICAO-endorsed AVSEC Training Programme, and offers aviation security training and certification to airlines, airports and authorities globally. A broad incumbent and indirect competitor whose standards Redline's curriculum must align to.
• Securitas: Global security services provider offering aviation security guarding, screening and consulting for airports and airlines alongside its broader physical security portfolio. A broad incumbent whose scale and bundled offerings compete with Redline on enterprise contracts, particularly in managed services and embedded personnel.
• Allied Universal (G4S): One of the largest global security services companies offering aviation screening, guarding and risk consulting through legacy G4S and aviation-focused units. Competes with Redline on end-to-end aviation security services for large airports and government clients.
• ACI World (Airports Council International): Global airport industry association providing ICAO-aligned aviation security training programmes, APEX accreditation and security excellence initiatives for member airports. Comparable as a training-standards body competing with Redline's ASTC credential for institutional training budgets.

Emerging players

• IDEMIA Public Security: Provider of biometric and identity-based passenger screening solutions for airports and borders, with adjacent training and integration services. Compares as an adjacent technology provider influencing the screening and training ecosystem in which Redline's TIRT operates.
• Smiths Detection: Manufacturer of X-ray, CT and trace detection screening equipment used in airports globally, with training programmes tied to its hardware. Comparable as an equipment-and-training ecosystem peer whose CT machine deployments drive demand for Redline's TIRT CT training content.
