What TDSi does

TDSi (Time and Data Systems International) is a Poole, UK-based designer and manufacturer of integrated access control systems, founded in 1982 and operating as a subsidiary of France-headquartered Vitaprotech Group since 2024. Its product portfolio centres on the proprietary GARDiS platform - comprising the GARDiS Web Embedded Controller (1-44 doors, up to 5,000 credentials), the GARDiS Network Controller (up to 50,000 credentials), GARDiS PRO and EXpress browser-based management software, and a reader range covering proximity, MIFARE/DESfire, dual-technology, long-range RF, and Bluetooth Low Energy (with five identification modes and smartphone credentials). Legacy EXpert, EXcel, MICROgarde, and SOLOgarde controllers plus EXgarde software remain in the catalogue, with EXgarde classified end-of-life from May 2024 and supported until May 2027 via a migration programme to GARDiS.

The business monetises across hardware sales (controllers, readers, cards/fobs with 3-5 year warranties), one-time and tiered software licences (GARDiS EXpress/PRO), recurring Base and Bespoke Software Support Agreements, certified installer training delivered at Poole HQ, Coventry, and on-site, and EXgarde-to-GARDiS migration services. Go-to-market is overwhelmingly indirect: a two-tier channel of authorised distributors (e.g., ADI Global, Anixter, Oprema, Norbain in the UK; ITESA, SODA, Ditec in France; SIEL in Romania; Vimo in Italy; Databac in Spain; AMED in the Middle East; ASVS in Africa; VASTIQ and Comvision in Asia/Australia) layered with a Gateway Training-certified installer network (Authorised, Gold, Platinum tiers), supplemented by direct engagement at The Security Event (NEC Birmingham), ISC West (Las Vegas), and Intersec Dubai. End-customers are diversified across education, healthcare, government, commercial, industrial, transportation, and sports & leisure verticals, with named logos including Shanghai Metro, Bristol International Airport, LV= Liverpool Victoria, Aston Villa FC, and multiple UK universities and hospitals.

The company holds ISO9001:2015 (BSI), Cyber Essentials Plus, GDPR, WEEE, and RoHS2 compliance, and integrates with a broad third-party ecosystem covering VMS (Milestone, Pelco, Hanwha, Hikvision, Dahua, Panasonic), biometrics (Suprema, IDEMIA), intruder alarms (Texecom, Vanderbilt), wireless locks (Assa Abloy Aperio, SimonsVoss, U&Z), identity (Microsoft Active Directory), and elevator control (Otis, Fujitec). Headcount is reported at 11-50 employees, and the business is privately held with no disclosed funding history.

Recent moves7 records

Expansion highlights6 records

Direct peers

• Inner Range: Manufacturer of integrated access control and intruder detection systems (Integriti, Concept) with strong UK and Australian presence. Comparable in targeting enterprise and high-security sites with a full hardware-plus-software stack.
• Paxton Access: Brighton, UK-based manufacturer of access control systems (Net2, Paxton10) targeting the same mid-market and SME installers across the UK. Closest direct competitor to TDSi in scale, geography, and product scope.
• Vanderbilt Industries (ACRE): Provider of access control controllers, readers, and management software (ACT, SMS) across Europe. Direct competitor in the same mid-market access control segment with overlapping integrator channels.

Emerging players

• Verkada: Cloud-native access control and video security provider with strong US enterprise traction. Represents the SaaS/cloud direction of the market that TDSi's on-prem GARDiS model is benchmarked against.
• Brivo: Cloud-based access control SaaS platform serving commercial and multifamily markets. Competes indirectly with TDSi by offering a managed subscription model that contrasts with TDSi's on-prem, license-based approach.

Broad incumbents

• Genetec (Synergis): Genetec's Security Center includes Synergis access control alongside its market-leading VMS, with cloud options (Security Center SaaS). Competes with TDSi in enterprise and integration-rich deployments but covers a much broader security stack.
• Axis Communications (Axis Entry Manager): IP-camera leader that has expanded into network access control with Axis Entry Manager. Competes with TDSi in IP-native, network-attached access control deployments, often leveraging its dominant camera footprint.
• HID Global (Mercury/Linu): ASSA ABLOY-owned identity and access management leader offering controllers (Mercury), readers, credentials, and mobile access. Competes with TDSi across virtually every vertical and product category at a much larger scale.
• LenelS2 (OnGuard): Carrier-owned provider of OnGuard access control, widely deployed in enterprise, government, and education. Direct product overlap with TDSi at the higher end of the market.
• Honeywell Access Control (Pro-Watch): Honeywell's building technologies division offers Pro-Watch and OmniAssure access control as part of a much broader building management portfolio. Competes with TDSi in enterprise and government sites but typically at larger scale.
