Top Cyber Security Companies In Manchester For 2026

Meta description: Compare cyber security companies Manchester businesses trust for 2026: CREST pen testers, 24/7 SOC and MDR providers, Cyber Essentials bodies and forensics.

Manchester has become one of the UK’s most important cyber security cities, and the range of cyber security companies Manchester organisations can choose from now runs from global incident response firms to two-person research consultancies. GCHQ has a permanent presence here, the city hosts a dedicated digital security hub, and the region’s universities feed a deep talent pool.

That choice makes it harder to know who to call. This guide groups specialists by what they actually do: penetration testing and red teaming, Cyber Essentials and ISO 27001 certification, 24/7 security operations centre and managed detection and response, and digital forensics and incident response. Accreditations such as CREST, IASME and NCSC assurance are only mentioned where a firm shows them on its own site, alongside a Greater Manchester office, so you can compare cyber security services in Manchester on evidence.

Security works best alongside well-run IT. If your day-to-day systems also need attention, see our guides to managed IT service providers in Manchester and IT support companies in Manchester.

Best Cyber Security Companies In Manchester

1. NCC Group — Spinningfields-Headquartered Global Cyber Security And Incident Response Firm

NCC Group is the largest name on this list and the one with the deepest Manchester roots. Its global headquarters is in the XYZ Building on Hardman Boulevard in Spinningfields, and the business traces its heritage back to the UK’s National Computing Centre in the 1960s. Founded in its current form in 1999, it now has more than 1,800 experts across the UK, Europe, North America and Asia Pacific.

Its services cover the full lifecycle: digital forensics and incident response with a 24/7 hotline, technical assurance and penetration testing, managed services including managed extended detection and response, consulting and implementation, and threat intelligence. Accreditations include multiple CREST memberships covering red teaming, threat intelligence and incident management, CBEST for financial sector testing, Cyber Essentials Plus and participation in the NCSC Industry 100 scheme. It works with financial services, government, technology, energy and healthcare organisations.

NCC Group suits large enterprises, banks and public bodies that need regulator-recognised testing such as CBEST, global incident response capacity, or a single supplier able to cover assurance and managed detection at scale.

2. Secarma — Hulme-Based CREST Penetration Testing And NCSC Assured Consultancy

Secarma is based at Birley Fields in Hulme and has been helping organisations identify and reduce cyber risk for more than 20 years. It structures its work around what it calls the ACT framework: Advise, covering maturity assessments, ISO 27001 support, virtual CISO and threat modelling; Certify, covering Cyber Essentials, IASME Cyber Assurance, ISO 27001 and the IoT Cyber Scheme; and Test, covering web, mobile, cloud and infrastructure penetration testing and red teaming.

The accreditation list is one of the strongest among independent Manchester firms. Secarma is CREST accredited, an NCSC Assured Service Provider, a Cyber Essentials Certification Body, IASME Cyber Assurance certified and a member of the IoT Security Foundation, and it holds ISO 9001 and ISO 27001 itself. It publishes a Net Promoter Score of +86.8. The team spans penetration testers, red team specialists, compliance experts and security consultants, so testing findings can feed straight into certification work.

Secarma is a strong fit for organisations that want one partner to test their defences, fix the gaps and then certify against a recognised standard, including manufacturers of connected devices who need IoT assurance.

3. Predatech — Spring Gardens CREST Consultancy That Has Issued 2,000+ Cyber Essentials Certificates

Predatech is a CREST accredited cyber security consultancy based on Spring Gardens in Manchester city centre, serving more than 300 organisations. Its services include penetration testing, penetration testing as a service, managed vulnerability scanning including PCI ASV approved scans, cloud and server security reviews, ISO 27001 and IASME Cyber Assurance consultancy, and Cyber Essentials certification.

Cyber Essentials is where Predatech has built real volume. As a certification body for both Cyber Essentials and Cyber Essentials Plus, it has issued more than 2,000 certificates, and assessments are carried out by IASME and CREST qualified professionals. The firm is also a Crown Commercial Service provider, making it easier for public sector buyers to engage. It emphasises plain-English reporting with prioritised recommendations and transparent pricing. Named clients include Introhive, Collingwood, OCS, Chetwood and Lloyds Pharmacy.

Predatech suits SMEs that need Cyber Essentials to win contracts or satisfy insurers, payment-handling businesses that require PCI approved scanning, and growing firms that want regular penetration testing without enterprise pricing. Its city centre office on Spring Gardens also makes face-to-face scoping meetings easy for businesses in the commercial core.

4. Cyphere — Founder-Led CREST Penetration Testing Firm In Altrincham

Cyphere was founded in 2021 by Harman Singh, who still personally leads engagements, and operates from Kennedy House on Stamford Street in Altrincham. It is a CREST accredited penetration testing firm covering infrastructure, cloud, web applications and mobile, alongside vulnerability assessments, compliance audits and managed security services.

The delivery model is deliberately senior: the founder works with a hand-picked team holding certifications such as OSCP, OSCE, CISSP, CEH and AWS and Azure security credentials. Cyphere is also an IASME certification body for Cyber Essentials Plus and a G-Cloud supplier to the public sector. Its commercial promise is simple and useful for buyers: no on-site expenses, no cancellation charges and free retests once you have fixed the findings. Clients range from Manchester SMBs to multinational European companies in fintech, retail, healthcare, life sciences and higher education.

Cyphere suits technology companies and regulated businesses that want experienced testers rather than juniors on their engagement, and buyers who value predictable costs, including retesting, when budgeting for annual assessments. Mostly remote delivery also keeps engagements quick to schedule for clients outside the North West.

5. RM Information Security — Circle Square Penetration Testing Specialist Founded In 2015

RM Information Security was founded in November 2015 by Mark Wityszyn, its Technical Director, and Rob Euston, its Business Director, and has its Manchester office at No.1 Circle Square on Oxford Road. The firm specialises in penetration testing: application and web, external and infrastructure, mobile app, cloud and red team testing, plus information security consultancy and a lighter website security health check.

Quality assurance is built into the business. RM Information Security holds ISO 27001 and ISO 9001 certification, and its testers include Cyber Scheme Team Leader qualification in web application testing, one of the more demanding UK testing credentials. The company describes its approach as built around technical excellence and clear communication, and client testimonials from telecoms, software and financial services firms highlight its risk-based testing and its ability to adapt as requirements change.

RM Information Security suits software houses and SaaS companies that ship web applications frequently, and financial services firms that want a long-term testing partner who learns their environment year on year. Its website security health check is a sensible low-cost first step for smaller businesses.

6. Digital Interruption — Piccadilly Place Security Research Consultancy Specialising In Mobile

Digital Interruption was founded in 2017 by Jahmel Harris and Saskia Coplans and works from Colony at Piccadilly Place. It describes itself as a team of security researchers, developers and penetration testers with a particular focus on mobile technology, and offers penetration testing across web, mobile, API and networks, vulnerability scanning, code review, cloud review, secure development and consultancy.

Its research credentials are unusual for a firm of its size. The team has contributed more than 30 registered CVEs, won Innovate UK grants three times and released open source security tools including RAPTOR, an AI-based APT classifier, and Protodump. Clients range from NATO and FTSE 250 companies to SMEs. Saskia Coplans sits on the Greater Manchester Cyber Advisory Group and the OWASP Education Committee, leads the local OWASP chapter and was named one of SC Magazine’s Top 30 Female Cybersecurity Leaders in 2022.

Digital Interruption is a natural choice for companies building mobile apps or APIs, and for development teams that want testers who can also review code and help build security into the product.

7. CYFOR Secure — Middleton-Based Incident Response, Forensics And Managed Security Provider

CYFOR Secure is the cyber security division of CYFOR, a digital forensics group established in 2002 whose Manchester secure operations site is at Benjarron House on Greenside Way in Middleton. CYFOR Secure has more than 75 staff and over 2,000 clients, and splits its work between proactive services such as audits, Cyber Essentials and ISO 27001, vulnerability scanning, penetration testing, managed endpoint protection, SIEM and phishing simulation, and reactive services.

The reactive side is what sets it apart. CYFOR Secure provides cyber incident response and digital forensics, ransomware negotiation support, insurance-backed response and business remediation after a breach. That draws on the wider group’s forensic laboratory, which holds ISO 17025 accreditation from UKAS, the standard for testing laboratories and an important factor where evidence may end up in court. CYFOR Secure holds ISO 9001, ISO 14001 and ISO 27001, and CYFOR has been named a trusted partner of the Cyber Resilience Centre for Greater Manchester.

CYFOR Secure suits organisations that want an incident response retainer with genuine forensic capability, insurers’ panels and legal teams, and businesses that want prevention and response from the same provider.

8. Cyber Security Specialists — Altrincham Business Park Consultancy With CREST Testing And Incident Response

Cyber Security Specialists has been supporting clients for more than ten years from Altrincham Business Park and works with organisations ranging from start-ups to government departments. Its service list is broad: CREST accredited penetration testing, Cyber Essentials and Cyber Essentials Plus certification, ISO 27001 consultancy, cyber maturity assessments, managed security services including SOC, dark web monitoring and vulnerability scanning, virtual CISO and virtual DPO services and security awareness training.

The firm holds CREST accreditation for both penetration testing and incident response, which is less common among smaller consultancies, alongside Cyber Essentials Plus, ISO 27001, ISO 9001, IASME and Defence Cyber Certification. It is a supplier to the UK Government, and clients referenced on its site include the Department for Work and Pensions, payments firm Modulr, Total Mobile and a number of local authorities.

Cyber Security Specialists suits public sector bodies and defence supply chain businesses that need specific certifications, and SMEs that want a fractional CISO and data protection officer rather than hiring full-time security leadership. Having both testing and incident response accreditation under one roof also helps when a test uncovers signs of a live compromise.

9. EmergeCyber — Didsbury Provider Of Continuous Pen Testing And A digitalCISO Platform

EmergeCyber is based at Adamson House on Towers Business Park in Didsbury and takes a different approach to testing from most firms on this list. Rather than a single annual penetration test, it offers continuous network penetration testing and continuous web application and API testing, typically run monthly, alongside continuous data protection, continuous threat intelligence and a secure network-as-a-service platform.

Results and activity are managed through its digitalCISO platform, a central dashboard for reports, insights and security tasks. The company’s stated philosophy is that total security is impossible and that the job is to keep finding and fixing the most important weaknesses as systems change. EmergeCyber shows a CREST Pathway badge, is a longstanding member of Manchester Digital and the North West Cyber Security Cluster, and lists clients including Livv Housing Group, Macmillan, St Margaret’s Hospice, Peermusic and Cricket South Africa.

EmergeCyber suits organisations whose networks and applications change too often for an annual test to stay relevant, and smaller firms that want a dashboard view of security without employing a CISO.

10. CloudGuard — Manchester-Headquartered AI-Driven MDR Provider With A CREST Accredited SOC

CloudGuard was founded in 2020 by Matt Lovell and Javid Khan and moved its headquarters from London to Manchester city centre in February 2024. It now operates from Linley House on Dickinson Street, and in June 2024 launched its Manchester security operations centre to provide 24/7 monitoring for UK and international customers. Its core offer is managed detection and response through the Protect+ service, alongside cloud security, governance consulting, incident response and offensive security testing.

The technology at the centre is ANSEL, CloudGuard’s own AI-powered engine that automates detection and response. The company’s credentials are strong for a young business: its SOC is CREST accredited, it is an NCSC Incident Response Assured Partner, and it holds ISO 27001, ISO 9001 and Cyber Essentials Plus. It received funding from the Northern Powerhouse Investment Fund II and reports 100 percent customer retention.

CloudGuard is a good match for small and mid-sized businesses that need round-the-clock detection and response but cannot justify an enterprise SOC, particularly those running on Microsoft cloud platforms. Its growing Manchester team is also a sign of commitment to the city.

11. Aruga Cyber — Microsoft Sentinel Managed SOC Provider At The Greater Manchester Digital Security Hub

Aruga Cyber has its Manchester office at Heron House on Lloyd Street, home of the Greater Manchester Digital Security Hub, with a second office in Luton. It provides an enterprise managed security operations centre, incident response through assurance, retainer and emergency options, threat exposure management, compromise assessments and consultancy covering SOC reviews, cloud security audits and framework gap analysis.

Aruga’s SOC is built on Microsoft Sentinel running inside the client’s own Azure environment, so the customer keeps ownership of its data and detection rules. The firm quotes an average threat containment time of 60 seconds, a reduction in false positives of up to 90 percent within 30 days, full SOC deployment in a day and a record of zero SLA breaches. All staff are UK-based with BPSS clearance as a minimum. It is an NCSC Assured Incident Response provider, a Microsoft Solutions Partner and a Crown Commercial Service supplier, with ISO 27001, ISO 9001 and Cyber Essentials Plus.

Aruga Cyber suits Microsoft-centric organisations, including public sector bodies, that want a managed SOC without handing their security data to a third-party platform.

12. Zenzero — King Street Office Of A National MSP With CREST Accredited Security Services

Zenzero has a Manchester office at 82 King Street, part of a national network of 17 locations with head office in London. The group has been operating for more than 20 years, employs over 850 technology specialists and supports more than 450,000 users. Its Manchester cyber security offer covers managed detection and response, endpoint detection and response, network monitoring and threat detection, SOC services, penetration testing with red and blue teaming, dark web monitoring and OSINT investigations.

Zenzero is CREST accredited and holds ISO 9001, ISO 27001, Cyber Essentials and Cyber Essentials Plus, with Microsoft partner designations that include Security. It also supports clients through Cyber Essentials and ISO 27001 certification. Because it is also a large managed service provider, the security team can work directly with the engineers who run a client’s infrastructure, which shortens the path from finding a vulnerability to fixing it. Sectors served include financial services, healthcare, biotech and professional services.

Zenzero suits mid-sized organisations that want CREST accredited testing and 24/7 detection from a provider big enough to remediate what it finds, especially those with offices in several UK cities.

How To Choose A Cyber Security Company In Manchester

Can Someone Be On Site Within Hours?

Check the address on the company’s own website and ask where testers and SOC analysts are actually based. For incident response, a cyber security consultant in Manchester who can attend site within hours is very different from a remote-only provider.

Which Accreditations Matter For Your Needs?

For penetration testing, look for CREST or Cyber Scheme qualified testers. For Cyber Essentials, use a certification body licensed by IASME. For incident response, NCSC Assured or CREST incident response accreditation is the benchmark. For forensic work, UKAS ISO 17025 accreditation matters if evidence may be used in court.

Do You Need Testing, Monitoring Or Both?

Penetration testing shows you where you are weak at a point in time. Cyber security managed services in Manchester, such as SOC and MDR, watch for attacks around the clock. Many organisations need both, but they do not always need them from the same company.

How Will Findings Be Fixed?

A report is only useful if someone acts on it. Ask whether the provider retests for free, how findings are prioritised, and whether it works directly with your IT provider. If your IT is outsourced, check that your MSP and your security firm have a clear handover.

What Happens On The Worst Day?

Ask for the incident response process in writing: hotline, response times, who attends and how costs are charged. Check whether your cyber insurer has a panel of approved responders before you sign a separate retainer.

Conclusion

Manchester’s cyber security market is deep enough that you can match a specialist to almost any need, from founder-led penetration testing and high-volume Cyber Essentials certification to AI-assisted SOCs and court-grade forensics. The firms in this guide all have verifiable Manchester offices and credentials published on their own websites, which is the right starting point for any shortlist of cyber security companies Manchester buyers can trust.

Decide first whether you need assurance, monitoring or response, then ask two or three providers for scoped proposals and references from organisations like yours. Firms that also need help being found online can compare our guide to SEO agencies in Manchester covers the city’s search specialists.
