The short answer

Cyber Essentials and Cyber Essentials Plus certificates issued by Sovereign Secure are listed on the free IASME certificate search, which covers every certificate issued in the last 12 months. PCI DSS has no public register: ask the organisation for its Attestation of Compliance, check that Sovereign Secure is named as the assessor, then email us to confirm it.

Sovereign Secure certificate verification depends on what you have been shown. A Cyber Essentials or Cyber Essentials Plus certificate we issued is listed on the IASME certificate search, the official search for the NCSC scheme, so you can check it yourself for free without contacting us. PCI DSS, PCI PIN and card production results are confidential and have no public register, so you verify them from the Attestation of Compliance (AOC) and a short email to us.

We do not run a separate register of our own. The official sources below are the ones a procurement team should rely on, and this page shows you how to read them. It is also the home of our badge programme for certified clients.

How does Sovereign Secure certificate verification work?

Find the document you hold in the table, then follow the matching section below. Each credential has a different issuer and a different place to check it.

What you have been shown Who issues it Public register? How to verify it
Cyber Essentials certificate Sovereign Secure, as an IASME-licensed certification body Yes: IASME certificate search Search the organisation’s name for the level and dates; read the scope and certification body on the certificate
Cyber Essentials Plus certificate Sovereign Secure, after a hands-on technical audit Yes: the same search, shown as Plus As above, and confirm the level says Plus
IASME Cyber Assurance or Defence Cyber Certification certificate Sovereign Secure, as an IASME-licensed certification body (Defence Cyber Certification Levels 0 and 1 only) Yes: IASME runs a separate certificate search for each scheme Use the IASME Cyber Assurance search or the Defence Cyber Certification search, then compare with the certificate
PCI DSS Attestation of Compliance The assessed organisation, signed by our lead QSA where we performed the assessment No: the PCI SSC keeps no register of compliant companies Ask for the AOC, check the assessor and date, then email us
PCI PIN or card production assessment Sovereign Secure as a QPA or CPSA company, reported to the payment brands No Ask the organisation, then email us
ISO 27001, 9001 or other ISO certificate MQA International, our partner certification body Held by the certification body Contact MQA International with the certificate number
Penetration test A report, not a certificate No Ask for the report or its summary, then email us

How do I verify a Cyber Essentials certificate issued by Sovereign Secure?

Search the organisation’s name on the IASME certificate search and read the result. It should show a certificate issued within the last 12 months with the correct level. The search result does not name the certification body or the scope, so check those on the certificate itself, which names Sovereign Secure for certificates we issued. The search is free and needs no account.

  1. Open the certificate search. The NCSC directs people to it on IASME’s website, because IASME delivers the scheme for the NCSC.
  2. Enter the organisation’s name. Try its registered name from Companies House as well as any trading name.
  3. Read the matching result: company name, certificate reference, certificate level, certification date and expiry date.
  4. Compare it with the certificate the supplier gave you, which also shows the scope and the certification body, using the table below.
  5. If anything does not match, or the organisation is not listed, email us before you rely on it.
Field What good looks like Red flag
Organisation name The legal entity you contract with A parent, sister or trading company you do not contract with
Level Cyber Essentials Plus, if your contract or tender asks for Plus Only basic Cyber Essentials when Plus was claimed
Issue date Within the last 12 months Older than 12 months: the certificate has expired
Scope Whole organisation, or a described scope that covers the service you buy A scope limited to a part of the business you do not use
Certification body Sovereign Secure, for certificates we issued Another body: verify with them instead
Certificate number The same as on the digital certificate or PDF you were sent Different, or the supplier cannot provide one

IASME asks that the search is used only to check certification, not for marketing or data research. Organisations checking many suppliers can register for the IASME Supplier Assurance Tool, a free platform for checking certification across a supply chain. For a screen-by-screen walkthrough, see our guide on how to check a Cyber Essentials certificate, and for what the higher level involves, see Cyber Essentials Plus.

Usually because the certificate has expired, the organisation is certified under a different name, or another certification body issued it. The common causes are:

  • Expired. The search only covers certificates issued in the last 12 months. A lapsed supplier needs to renew its Cyber Essentials certificate before it counts again.
  • Different name. The certificate is issued to the legal entity in scope, which may be a parent company or a registered name that differs from the brand you know.
  • Different certification body. If the certificate names another body, ask that body to confirm it. We can only confirm certificates we issued.
  • Not certified. Wording such as “working towards Cyber Essentials” or “Cyber Essentials compliant” is not certification. Only a certificate from a licensed certification body counts.

If you still cannot find it, email [email protected] with the organisation’s name and the certificate number. We will tell you whether we issued it and whether it is current.

How are PCI DSS Attestations of Compliance verified?

Ask the organisation for its current AOC, check that Sovereign Secure is named as the assessor and that the assessment is less than 12 months old, then email us to confirm it. The PCI Security Standards Council does not certify merchants or service providers and publishes no list of compliant companies, so the AOC is the evidence.

The full Report on Compliance (ROC) is confidential and normally stays between the organisation, its acquirer and the payment brands. The AOC is the summary designed to be shared with customers and partners, often under a non-disclosure agreement.

Check Where to look Why it matters
Assessed entity Contact details in Part 1 of the AOC It must be the company you contract with
Assessor Assessor details in Part 1 For assessments we performed, it names Sovereign Secure Ltd and the lead QSA
Assessor status The PCI SSC list of Qualified Security Assessor companies and its professionals lookup Confirms the company and the individual assessor were qualified
Validation route Whether the AOC follows a ROC or a self-assessment questionnaire (SAQ) An SAQ is the organisation’s own self-assessment, even where a QSA advised; a ROC records a full assessment
Services covered The executive summary in Part 2 The services you buy must be inside the assessed scope
Result and date The validation and signatures in Part 3 It should say “Compliant” and be dated within the last 12 months

PCI DSS compliance is revalidated every year, so an older AOC is out of date. Service providers may also appear on Visa’s Global Registry of Service Providers or Mastercard’s list of compliant service providers, but those listings run through the card brands’ own programmes, so absence from them does not prove non-compliance.

Treat a “PCI certificate” on its own with care. It is not a PCI SSC document and does not replace the AOC. The same principle applies to our PCI PIN security audits and card production audits as a QPA and CPSA company: results go to the payment brands, not to a public register. Read more about our PCI DSS assessments.

How do I add the “Certified by Sovereign Secure” badge to my website?

Ask us for your badge snippet once your certificate is issued. It pairs the official Cyber Essentials or Cyber Essentials Plus digital badge from your IASME digital certificate with a short “Certified by Sovereign Secure” text link, so visitors can see who certified you and how to check it.

IASME issues certificates digitally, and certified organisations receive a digital Cyber Essentials badge to display on their website. We do not host, copy or alter the Cyber Essentials marks: you embed the badge exactly as IASME provides it and follow IASME’s branding guidelines. The official rules for the marks are covered in our guide to the Cyber Essentials logo; this section covers only our own snippet.

Our snippet adds one plain text line beneath it, for example “Cyber Essentials Plus certified by Sovereign Secure, an IASME-licensed certification body”, linking to our Cyber Essentials certification page or to this verification page.

Where What to show
Website footer The IASME badge and the text line, on every page
Security or trust page Badge, text line, certificate number and renewal month
Tender and supplier portals Certificate number and a link to the IASME search
Email signature The IASME digital badge only

A few rules keep the badge credible:

  • Show the level you hold. Never display the Plus badge with a basic certificate.
  • Do not redraw, recolour or crop the Cyber Essentials marks, or take them from another website.
  • Do not imply the certificate covers more than its scope.
  • Remove the text line if your certificate lapses, and renew before expiry to keep both.

To request the snippet, email [email protected] with your organisation’s name and certificate number, or use the form below. It is available on request to organisations we have certified.

Can PCI clients say they were assessed by Sovereign Secure?

Yes, if you hold a current, compliant AOC from an assessment we performed and you want to say so. We supply a plain-text line such as “PCI DSS assessed by Sovereign Secure, a PCI SSC Qualified Security Assessor company”.

  • Never use the PCI SSC logo, and never say the Council itself certified you.
  • Name the standard and version you were assessed against.
  • Remove the line if your AOC is more than 12 months old and has not been revalidated.
  • We check the wording with you against the PCI SSC’s rules on use of its name and marks before you publish.

Can my organisation be listed on this page?

Yes, if you want to be. Listing is opt-in: tell us when you request your badge snippet, and we will only add your name and a link to your website once you have agreed in writing. The organisations we already name, from banks to card manufacturers, are on our clients page.

FAQ

Frequently asked questions

Can't find your answer? Call us on +44 161 523 5276 or send us a message.

Does Sovereign Secure keep its own certificate register?

No. Cyber Essentials and Cyber Essentials Plus certificates appear on the official IASME certificate search, and PCI results are confidential to the assessed organisation, so we point you to the official source rather than a copy of it.

How long does a certificate we issued stay on the IASME search?

Twelve months from the issue date, for both Cyber Essentials and Cyber Essentials Plus, after which it drops off the search unless it has been renewed. Plus must be completed within three months of the basic certificate. Our guide to the Cyber Essentials certificate check explains what the search shows.

Can you confirm a certificate for me by email?

Yes. Email [email protected] with the organisation's name and the certificate number, and we will tell you whether we issued it and whether it is current.

Is a PCI certificate the same as an Attestation of Compliance?

No. The PCI Security Standards Council does not certify merchants or service providers, so any certificate is an assessor's courtesy document. The AOC is the official evidence of a PCI DSS assessment.

Who issues the ISO certificate if Sovereign Secure is our consultant?

MQA International, our partner certification body, carries out the certification audit and issues the certificate, so verify ISO certificates with them. See our ISO 27001 consultancy page for how the two roles fit together.

Can we use the Cyber Essentials logo on our website?

Yes, once you are certified; our guide to the Cyber Essentials logo explains where the badge comes from and the rules for using it.

What happens to our Sovereign Secure badge when the certificate expires?

Your certificate drops out of the IASME search 12 months after issue, so remove the "Certified by Sovereign Secure" line and any static copy of the Cyber Essentials badge when it expires; the embedded IASME badge disappears by itself. Renewing before expiry lets you keep both in place.

Does a parent company's certificate cover its subsidiaries?

Only if the subsidiary is inside the certificate's scope. The IASME search does not show scope, so ask for the certificate itself and read its scope before you rely on it.
