What SEIBER LIMITED does

SEIBER LIMITED is a privately held UK cyber security consultancy and accredited training provider founded in 2017 and headquartered in Horwich, Bolton (Company Number 11087884). The firm delivers three integrated lines of business: (1) a catalogue of eight training courses spanning NCSC Assured OSINT (Introduction and 5-day Practitioner), ISACA-accredited CISM and CRISC exam preparation, BCS-accredited CISMP, Business Continuity Management, Cyber Security Awareness, and Executive AI Governance; (2) bespoke OSINT consultancy covering investigations, digital footprint analysis, due diligence, and brand reputation management; and (3) Cyber Essentials and IASME Cyber Assurance Certification Body services. Its core technology is OSINT tradecraft methodology combined with an instructor-led training platform; the firm does not develop AI or software products but trains practitioners and executives.

The business model is professional services and fee-based training, with no disclosed external funding. Course pricing ranges from £480 (1-day OSINT introduction) to £3,960 (5-day OSINT Practitioner), with mid-tier 3–4 day certification prep courses priced £2,100–£2,880. Cyber Essentials and IASME certifications are tiered by organisation size from £320 (micro, 0–9 employees) to £800+ (assisted). Distribution combines self-serve website e-commerce for individuals, open public programmes in London and Manchester plus virtual instructor-led delivery for mid-market buyers, and direct in-house or sector-tailored delivery plus bespoke consultancy for enterprise and government clients. The firm monetises a UK-focused, primarily English-speaking buyer base across public sector, armed forces (via ELCAS funding), maritime, corporate security teams, and SMBs seeking certification.

The firm operates at a micro scale (1–10 employees) and is led by Managing Director Anthony Daly, whose 22-year Royal Navy maritime cyber security background anchors the firm's talent proposition. Competitive positioning rests on a rare stack of accreditations — NCSC Assured Training, ISACA, BCS, ELCAS (Provider 10968), IASME Certification Body, Cyber Essentials Certification Body, and APMG administration — alongside named enterprise engagements with a Critical National Infrastructure organisation, a UK Premiership Football Club, and a FTSE 100 organisation.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• ISC2: Global, non-profit cyber security certification body (CISSP, CCSP) running official training and exam prep programmes — incumbent in the same professional-certification training category as Seiber's CISM/CRISC/CISMP exam preparation courses.
• NCC Group: UK-listed cyber security consultancy and assurance provider offering training alongside source code audit, threat intelligence and incident response — broader incumbent competing for some of the same enterprise and public-sector training and advisory budgets.
• SANS Institute: Global leader in cyber security training with extensive GIAC certifications and instructor-led programmes, including OSINT and incident response content — comparable offering but vastly larger scale and broader geographic footprint than Seiber.
• KnowBe4: Large global vendor of security awareness and phishing simulation training — broader incumbent competing for the same enterprise security awareness budget that Seiber targets with its awareness and OSINT training courses.

Emerging players

• Authentic8: OSINT-focused technology vendor (Silk browser) and training provider serving investigators and analysts — partial overlap with Seiber's OSINT consultancy and training, but delivering primarily through tooling rather than classroom training.
• CybSafe: UK-based security awareness and behaviour-focused training platform — overlaps with Seiber's Cyber Security Awareness and OSINT awareness content but delivers primarily as SaaS rather than instructor-led classroom programmes.

Direct peers

• Tiger Scheme: UK-based accreditation and certification body for technical security testing, running assured training and practitioner examinations — a close structural analogue to Seiber's NCSC Assured OSINT training and Cyber Essentials/IASME certification body activities.
• OSINT Combine: US/UK OSINT training specialist offering practitioner-level courses and tradecraft content — directly comparable to Seiber's NCSC Assured OSINT Practitioner programme in target audience and curriculum.
• Protection Group International (PGI): UK-based cyber security and intelligence consultancy providing training and managed services to government and enterprise — directly comparable to Seiber's blended training-plus-consultancy model serving UK public sector clients.
• QA Limited: One of the UK's largest commercial technology and cyber training providers, offering accredited courses (including ISACA and BCS-aligned programmes), virtual and in-person delivery, and enterprise in-house training — directly comparable to Seiber's open-programme and in-house model.
