The short answer

IASME (Information Assurance for Small and Medium-sized Enterprises) is a UK cyber security certification company, The IASME Consortium Ltd. Since April 2020 it has been the NCSC's sole delivery partner for Cyber Essentials, licensing the certification bodies that assess organisations. It also runs its own schemes, including IASME Cyber Assurance and, with the MOD, Defence Cyber Certification.

IASME is the company that delivers the UK government’s Cyber Essentials scheme for the National Cyber Security Centre (NCSC). The name stands for Information Assurance for Small and Medium-sized Enterprises. The organisation behind it, The IASME Consortium Ltd, is a cyber security certification company based in the Malvern Hills, with offices in Belfast and near Edinburgh. It licenses the certification bodies that assess organisations, runs the platform that applicants use to answer the questions and operates several certification schemes of its own.

This page is about the organisation. If you want to get certified, our Cyber Essentials certification page explains the scheme, the process and the prices. Sovereign Secure is an IASME-licensed certification body for Cyber Essentials, Cyber Essentials Plus, IASME Cyber Assurance and Defence Cyber Certification Levels 0 and 1, so we work within IASME’s rules every day.

What does IASME stand for?

IASME stands for Information Assurance for Small and Medium-sized Enterprises. The name comes from a project funded by the Technology Strategy Board (now Innovate UK) to create an information security standard that small businesses could realistically meet, because ISO/IEC 27001 was seen as too demanding for many of them. The resulting standard was launched in 2011.

The IASME Consortium was incorporated as a company in January 2012 to take that work forward. Its own standard, first known as IASME Governance, is now called IASME Cyber Assurance. The SME focus explains the name, but IASME’s schemes now cover organisations of every size, and some of them certify connected devices and ships rather than organisations.

What does IASME do?

IASME runs cyber security certification schemes and the network of companies that deliver them. It does not normally assess you itself; a certification body it licenses does. In practice, IASME:

  • licenses and oversees certification bodies and the assessors who work for them;
  • publishes the question sets and runs the online assessment platform that applicants use;
  • issues certificates and digital badges, and runs the public certificate search;
  • delivers schemes for government: Cyber Essentials and Cyber Advisor for the NCSC, Defence Cyber Certification with the MOD and ASSURE for the Civil Aviation Authority;
  • writes and runs its own standards, such as IASME Cyber Assurance and its IoT and maritime schemes.

Is IASME the same as Cyber Essentials?

No. Cyber Essentials is the NCSC’s scheme, and IASME is the company the NCSC appoints to deliver it. The NCSC owns the scheme and sets the technical requirements. IASME publishes the question set, licenses the certification bodies and runs the assessment platform and certificate search. A certification body assesses you. Our page on how the Cyber Essentials scheme works explains that split in full.

IASME has been part of the scheme since it launched in 2014, when it was one of several accreditation bodies. In late 2019 the NCSC chose it to replace the arrangement under which five organisations delivered the scheme, and IASME has been the sole delivery partner since April 2020. There is no separate IASME version of the certificate: what people call “IASME Cyber Essentials” is the standard NCSC Cyber Essentials certificate, issued through IASME’s platform by a licensed certification body.

What schemes does IASME run?

Cyber Essentials is the best known, but it is one of a family of schemes. IASME is the NCSC’s sole delivery partner for Cyber Essentials and Cyber Advisor and one of its two delivery partners for Cyber Incident Response and Cyber Incident Exercising. Defence Cyber Certification was developed with the Ministry of Defence (MOD), ASSURE is delivered for the Civil Aviation Authority (CAA) and the other schemes are IASME’s own. This table summarises IASME’s list of schemes, checked on 13 October 2026, and also notes Cyber Baseline, which is no longer available.

Scheme What it covers Do we certify it?
Cyber Essentials and Cyber Essentials Plus Five baseline technical controls across an organisation’s IT Yes
Cyber Advisor Assured advisers who help small organisations put the Cyber Essentials controls in place No
Cyber Incident Response (Standard Level) and Cyber Incident Exercising Assurance of companies that respond to incidents or run incident exercises No
IASME Cyber Assurance A wider standard covering governance, risk, privacy and data protection, designed with smaller organisations in mind Yes, both levels
IASME Cyber Baseline (no longer available) Was a cyber hygiene certification for organisations outside the UK. In October 2026 IASME’s scheme page said it was no longer available and pointed to Cyber Assurance Not offered by anyone
Defence Cyber Certification Organisation-wide certification for UK defence suppliers, at Levels 0 to 3 Levels 0 and 1 only
IASME IoT Cyber (Baseline and Assurance grades) Individual connected devices, not organisations: Baseline covers the three ETSI EN 303 645 requirements behind the Product Security and Telecommunications Infrastructure Act 2022, and Assurance covers all 13 No
Maritime Cyber Baseline The cyber security of commercial vessels No
ASSURE IASME accredits the cyber suppliers that audit aviation organisations’ self-assessments against the CAA’s Cyber Assessment Framework for Aviation No

Sovereign Secure is listed on IASME’s Network Directory (checked 13 October 2026) for Cyber Essentials, Cyber Essentials Plus, IASME Cyber Assurance and Defence Cyber Certification Levels 0 and 1. For any other scheme, or for Defence Cyber Certification at Levels 2 and 3, the Network Directory (below) shows which organisations are licensed or assured to deliver it.

What is IASME DCC?

IASME DCC is Defence Cyber Certification, the certification scheme for UK defence suppliers that the MOD developed with IASME. IASME acts as the scheme’s Certification Authority and delivers it through assured certification bodies. Its four levels, 0 to 3, match the Cyber Risk Profiles that MOD contracts set under DEFCON 658: every level needs Cyber Essentials, and Levels 2 and 3 also need Cyber Essentials Plus. The MOD has asked all industry partners to reach Level 0 by 31 December 2026.

We certify Levels 0 and 1. Our page on DEFCON 658 and Defence Cyber Certification explains the levels, the controls behind each one and how certification works.

What is the IASME portal?

It is IASME’s online assessment platform, where you answer the Cyber Essentials questions, save your progress and submit your answers for marking. You get your login once you have bought an assessment, either directly from IASME or through a certification body, and you then have up to six months to complete it. A senior person in your organisation confirms the answers are accurate before you submit.

After you pass, IASME issues your certificate and a digital badge for your website. Our IASME portal guide walks through account set-up, answering, submitting and finding your certificate, and our guide to the Cyber Essentials logo and badge explains how to display it.

How do I check a certification body is IASME-licensed?

Search for it in IASME’s Network Directory, the official list of IASME-licensed certification bodies and NCSC-assured service providers. Each listing shows the certifications the company can deliver and its office location.

  1. Read the certifications line. The directory shows “NCSC Cyber Essentials” and “NCSC Cyber Essentials Plus” as separate entries. Not every certification body is qualified to carry out Plus audits, so if you need Plus, check that it appears in the listing. The same applies to IASME Cyber Assurance and to each Defence Cyber Certification level.
  2. Don’t confuse advisers with certification bodies. The directory also lists NCSC-assured Cyber Advisors and incident response providers. A company listed only for “NCSC Cyber Advisor” can help you prepare but cannot certify you.
  3. Match the legal name. Listings usually show a trading name, so compare it with the company’s registered name and number at Companies House.
  4. Check the certificate later. Your certificate names the certification body that issued it, and anyone can check a Cyber Essentials certificate on IASME’s free certificate search.

A licence is the minimum. When you compare certification bodies, also look at turnaround times, whether Plus audits are available on site and remotely, and whether prices are published. Our guide to choosing a Cyber Essentials assessor covers those points.

What does “IASME certification” mean?

It usually means one of three things, so check which one you are being asked for:

  • A Cyber Essentials or Cyber Essentials Plus certificate, issued under the scheme IASME delivers for the NCSC. This is what most UK tenders and supply-chain questionnaires mean.
  • IASME Cyber Assurance, IASME’s own standard, which goes further than Cyber Essentials into governance, risk management and data protection. UK organisations must hold a valid Cyber Essentials certificate before they can be assessed for it. We certify both, and our IASME Cyber Assurance certification page compares them.
  • Defence Cyber Certification, for suppliers to the MOD, at the level their contract sets. We certify DCC Levels 0 and 1.

If a customer or contract simply says “IASME certified”, ask which scheme and which level they need before you buy anything.

FAQ

Frequently asked questions

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

What does IASME stand for?

Information Assurance for Small and Medium-sized Enterprises. The name comes from a research project to create a security standard that smaller organisations could manage, and the company now works with organisations of every size.

Is IASME the same as Cyber Essentials?

No. Cyber Essentials is the NCSC's scheme, and IASME is the company the NCSC appoints to deliver it. IASME also runs other schemes that have nothing to do with Cyber Essentials, such as its maritime and IoT certifications.

Is IASME a government body?

No. The IASME Consortium Ltd is a company registered at Companies House (07897132), not a government department. It delivers some government schemes, including Cyber Essentials and Cyber Advisor, on behalf of the NCSC.

Does IASME assess my Cyber Essentials submission?

Not directly. A qualified assessor at an IASME-licensed certification body marks your answers and, for Cyber Essentials Plus, carries out the technical audit. IASME runs the platform, sets the question set and oversees the certification bodies.

How do I check a certification body is IASME-licensed?

Search for it in IASME's Network Directory and read the certifications on its listing. Cyber Essentials and Cyber Essentials Plus are shown separately, so confirm the body is listed for Plus if you need a Plus audit.

What is IASME certification?

Usually a Cyber Essentials certificate issued under the scheme IASME delivers, or IASME Cyber Assurance, IASME's own wider standard. For defence suppliers it can also mean Defence Cyber Certification. Check which one a customer or tender is asking for before you buy.

How does IASME's own standard compare with ISO 27001?

IASME Cyber Assurance is IASME's own standard, not ISO/IEC 27001, the international management system standard with 93 Annex A controls. IASME says some buyers accept its audited level as an alternative to ISO 27001 for small companies. See IASME Cyber Assurance certification.

What is the IASME portal?

It is the online assessment platform where you answer the Cyber Essentials questions and submit them for marking. See our IASME portal guide for a step-by-step walkthrough.
