What CYBERIS REPLY LIMITED does

Cyberis Reply Limited is a UK-based, CREST-accredited information security consultancy founded in 2011 and operating from Tewkesbury with a registered office in London. The firm delivers a portfolio of professional services organised into three practice areas: Assess (penetration testing, red teaming, cloud risk management, ransomware defence audits, continuous vulnerability assessment, attack surface discovery, Cyber Essentials), Detect and Respond (incident readiness and incident response), and Remediation (remediation planning). Its technical approach is consultant-led and methodology-driven, augmented by AI tools to accelerate analysis, with all findings validated by human experts before delivery.

The company is differentiated by a stack of UK security accreditations that are difficult to obtain: CREST membership for penetration testing, simulated targeted attack and incident response; CBEST approval from the Bank of England; CREST STAR-FS; CHECK; NCSC IT Health Check Service certification; ISO 27001 and ISO 9001:2015; IASME Cyber Assurance Level One; and Official Cyber Scheme sponsorship. It serves nine verticals with financial services, public sector and government, and defence and law enforcement treated as primary, alongside retail, healthcare, legal, education, SME, and technology as secondary segments.

The business model is project-based professional services: engagements are custom-scoped, priced per project, and delivered by senior consultants with dedicated project management and quality assurance. Go-to-market is direct, sales-led, and domestic (UK), with enquiries handled through website contact forms and phone, supplemented by content marketing (blog, LinkedIn, X, GitHub, Facebook) and conference participation. Revenue is not publicly disclosed; the company is privately held with no disclosed parent company, no institutional investment, and no disclosed funding rounds.

Direct peers

• NCC Group: UK-origin, publicly listed cybersecurity consultancy with CREST-accredited penetration testing, red teaming, and threat intelligence services to financial services and government. Direct competitor for the same regulated UK client base.
• Secarma: UK penetration testing and security consultancy with CHECK and CREST accreditations, overlapping with Cyberis on offensive security services to UK enterprise and government.
• Pen Test Partners: UK CREST-accredited penetration testing and red team boutique serving financial services, retail, and technology — overlapping service portfolio, accreditation set, and customer profile with Cyberis.
• Bridewell Consulting: UK-based CREST-certified cybersecurity consultancy offering penetration testing, red teaming, and managed security across critical infrastructure and financial services — competing head-to-head in the same regulated verticals.
• F-Secure (WithSecure): European cybersecurity firm with a substantial cyber consulting practice (acquired MWR Cyber Security) offering penetration testing and red team services — comparable European footprint and accreditation profile.
• NCC Group (already listed): Duplicate considered — see top entry.

Broad incumbents

• Mandiant (Google Cloud): Google-owned incident response and cyber consulting leader with deep red team and threat intelligence capabilities — competes for premium intelligence-led engagements but operates at significantly larger scale.
• Trustwave: Global MSSP and cybersecurity consultancy with CREST-aligned penetration testing and incident response; broader portfolio means overlap rather than direct head-to-head on UK-regulated pen testing.
• Protiviti: Global risk consulting and internal audit firm with a sizable cybersecurity practice including penetration testing, red teaming, and incident response — adjacent competitor for enterprise risk-led testing mandates.

Emerging players

• Bishop Fox: US-headquartered offensive security specialist with strong red team, pen testing, and attack surface management offerings — comparable technical niche though primarily US-focused rather than UK-regulated.
