Client feedback
Don't just take our word for it
The specialist team at Sovereign Secure provided valuable support throughout our EMV certification process. They demonstrated a keen understanding of PCI production requirements and expertly steered the audit to a successful conclusion. We commend them on their innovativeness in conducting the audit of our facility remotely and the proactive nature of their services. We want to make special mention of the Security Assessor, Agnes Ng for her professionalism, efficiency and undisputed industry knowledge. Agnes and her team at Sovereign Secure were a pleasure to work with and an excellent choice for anyone looking for security consultancy and assessment in the PCI Card Production Industry.

Sovereign Secure provided Payment Card Industry Compliance Services to Bamcard for the following standards: PCI CPSA, PCI DSS and PCI PIN. Even with the global COVID-19 pandemic, they managed to provide the best possible, knowledgeable support during the process of auditing and achieving compliance. The Sovereign Secure assessors were so helpful in these challenging times … with years of Payment Card Industry experience. We would happily recommend them to any company in need of the services mentioned.

Engaged Sovereign Secure for Penetration Testing and Cyber Essentials and received a professional and friendly service. The Cyber Security Services were delivered on time and price was competitive. I would highly recommend the team at Sovereign Secure … to any organisation.

Questions about our cyber security services

What are cyber security services?
Cyber security services are the assessments, certifications, consultancy and testing that protect an organisation’s systems and data, and prove it to customers and regulators. Ours cover PCI DSS compliance assessments, Cyber Essentials and Cyber Essentials Plus certification, ISO 27001 consultancy, and penetration testing and vulnerability scanning.
How do you choose a UK cyber security company?
Not all cyber security companies hold the approvals your customers ask for, so check them on the awarding bodies’ own registers: the PCI SSC assessor listings for PCI work and IASME’s directory for Cyber Essentials. Then ask for a written scope and price before work starts, and ask who will do the testing and whether any of it is subcontracted. Our guides on choosing a PCI QSA and choosing a penetration testing company go further.
What does Sovereign Secure do?
We are a cyber security compliance firm. We assess and certify organisations against PCI DSS, PCI PIN, PCI Card Production, Cyber Essentials and Cyber Essentials Plus, help them implement ISO 27001 and other ISO standards, and provide the penetration testing and vulnerability scanning those standards require.
Are you accredited?
Yes. We are approved by the PCI Security Standards Council as a Qualified Security Assessor (QSA), Qualified PIN Assessor (QPA), Card Production Security Assessor (CPSA), P2PE Assessor (Europe and USA) and 3DS Assessor, and we are a member of the PCI SSC Global Executive Assessor Roundtable (GEAR) for 2026 to 2028. We are also an IASME-licensed certification body for Cyber Essentials, IASME Cyber Assurance and Defence Cyber Certification Levels 0 and 1. We are ISO 27001 certified and registered with the ICO. Our About page lists where to verify each one.
How are your services priced?
Cyber Essentials starts at £320 + VAT for organisations with up to 9 employees, depending on company size and the level of support you want; see our Cyber Essentials prices. Cyber Essentials Plus, PCI, ISO and penetration testing work are quoted at a fixed price once we understand your scope.
Do you only work with UK companies?
No. We are headquartered in the UK with offices in the United States, Singapore, Dubai and Bangladesh, and have delivered PCI and ISO projects for clients across Europe, the Middle East, Asia and the Americas. Cyber Essentials is a UK scheme but is open to organisations anywhere.
How quickly can you start?
Cyber Essentials assessments can start as soon as you are ready to submit, and Gold package submissions are assessed within one working day. For PCI, ISO and penetration testing we agree a start date with you when we confirm scope and send the quote.
