In short

ISO 27001 certification in Ireland at a glance

INAB management systems certification accreditation refers to ISO/IEC 27001, yet none of the Irish instruments checked makes it compulsory. Buyers in Ireland ask for it anyway.

Security questionnaires from financial firms and software buyers often prompt Irish ISO/IEC 27001 projects. DORA gives the Central Bank of Ireland's regulated entities duties on ICT risk and third-party suppliers, though neither DORA nor the Central Bank's operational resilience guidance names the standard. The National Cyber Security Bill that will transpose NIS2 is listed for priority publication, and the NCSC describes a forthcoming certification scheme to be run with INAB. ISO/IEC 27001 certification is a separate and established route: a certification body accredited for the standard audits the information security management system in two stages and issues the certificate. Sterling's London office takes Irish organisations through scoping, risk assessment, the Statement of Applicability, internal audit and management review, with Effivity and Sterling Academy included in the engagement.

The need

Who needs ISO 27001 in Ireland, and what happens without it

In Ireland the question rarely comes from a law. It comes from the buyer, the regulator or the partner that wants proof before it signs. These are the organisations that get asked.

  • Technology, SaaS and cloud providers selling to Irish and EU customersProcurement teams ask suppliers for independent evidence of how information security is managed; an ISO/IEC 27001 certificate from an accredited body is a common answer.
  • ICT suppliers to banks, insurers and investment firmsDORA places ICT risk management and third-party risk duties on financial entities supervised by the Central Bank, and those duties pass into supplier contracts.
  • Organisations preparing for NIS2The National Cyber Security Bill that will transpose NIS2 is pending; an information security management system gives a base to build on once its measures are published.
  • Organisations watching the national cyber certification schemeThe NCSC describes a forthcoming certification scheme with NIS2-aligned measures, to be run with INAB; ISO/IEC 27001 is a separate, established route.
  • Funds and asset managers in the IFSCOutsourced administration and technology services are examined by clients and regulated firms.

Requirements

ISO 27001 requirements in Ireland

Strip away the vocabulary and ISO/IEC 27001 requires a company to prove six things about how it protects the information it holds.

You know what you are protectingThe scope is defined: the information, systems, locations and people that matter, and who inside and outside relies on them.
Management owns itTop management sets the information security policy and objectives, assigns roles and gives the effort the resources it needs.
You decided what could go wrong, and what to do about itSecurity risks are assessed against agreed criteria, and each is treated with a recorded choice of safeguards and the reasons for it.
The safeguards work every dayAccess, suppliers, devices, backups, incidents and staff awareness are managed as routine operations, not one-off projects.
You can show itPolicies, risk decisions and records are kept, so an auditor sees the system working in practice rather than on paper.
You check yourselvesSecurity performance is measured, internal audits and management reviews take place, and what they find is put right.

In Ireland these six sit alongside the local laws and regulations listed under drivers below; one system can evidence both. The detail is on the global hub: ISO/IEC 27001 explained →

How Sterling gets an Irish company certified

How to get ISO 27001 certified in Ireland

One team from the London office carries the work from scoping to certificate. Clients in Ireland are served from Sterling's London office, on-site where the work needs it and remotely otherwise.

  1. Discovery call and scopeEntities, locations, regulators and target date, agreed before any proposal.
  2. Gap assessment against ISO/IEC 27001 and the Irish requirements that apply to youControls you already run for your regulators and customers are reused, not rebuilt.
  3. Your system built with your team in EffivityRisks, controls, evidence, incidents and reviews in one live system the auditor can see.
  4. Internal audit, management review and corrective actionsYour internal auditors trained by Sterling; the evidence proven before the certification body arrives.
  5. Certification body stage 1 and stage 2, then surveillanceAn accredited body audits and decides. Sterling supports the audits and the three-year cycle.
Included in every engagement
  • End to end, from one team
  • Effivity ISO & GRC software
  • Preferential Sterling Academy access, with complimentary awareness training for your people
  • Internal auditor training for your audit team, as applicable to your standard
  • Vulnerability assessment on ISMS engagements

The Sterling Promise: 100% on-time completion, 100% success, 8,100+ client engagements.Sterling does not certify. Certification decisions stay with independent bodies.

Time

How long does ISO 27001 certification take in Ireland?

There is no standard duration: it depends on your scope and on how much of the system already runs. In Ireland these are the factors that set the timeline.

  • Number of sites, data centres and cloud services in scope
  • Maturity of the risk assessment and Statement of Applicability
  • Overlap with DORA or NIS2 measures already in place
  • How many suppliers hold or process the in-scope data

Sterling agrees a dated plan with you on the discovery call, once the scope is known.

Cost

How much does ISO 27001 certification cost in Ireland?

The cost has two parts: the consulting work to build and prove the system, and the certification body’s audit fees, which are quoted separately. In Ireland these factors move both.

  • Headcount and number of sites in scope
  • Number of systems and outsourced suppliers
  • Certification body audit fees quoted separately from consulting
  • Integration with ISO/IEC 27701 or SOC 2 work

Sterling gives one customised, all-inclusive proposal after the discovery call, never before the scope is agreed.

Choosing a partner

ISO 27001 consultants and certification bodies in Ireland

Two different organisations are involved. A consultant helps you build the system and prove it works; an accredited certification body then audits or assesses it and decides. Keeping the two separate is what makes the result credible to buyers and regulators.

  • Check that the body’s accreditation or approval covers ISO 27001 and your sector, and that its certificates can be verified online.
  • Ask the consultant how the local requirements in Ireland are mapped into the same system, so nothing runs twice.
  • Ask for client references in your sector; Sterling’s client letters are available on request.
  • Agree who owns the evidence and the tool after the engagement; with Sterling the system stays yours, in Effivity.

Accreditation, audit language and remote audits in Ireland

Use a certification body accredited for this standard by INAB, the Irish National Accreditation Board, or by an accreditation body within the international mutual recognition arrangements (Global ACI — Global Accreditation Cooperation Incorporated, formerly the IAF MLA); check that the accreditation scope covers the standard and your sector. Edition and transition details: ISO/IEC 27001 hub →

Audit language

English is the working language of Irish business, so audits and controlled documents are normally in English; agree the language with the certification body at application and follow any requirement in a tender or contract.

Remote and on-site

Remote audit elements are at the certification body's discretion under its accreditation rules; operational sites are normally visited on-site.

ISO 27001 in Ireland: questions clients ask

Is ISO 27001 required by Irish law?

No Irish law requires an ISO/IEC 27001 certificate. DORA and the Central Bank's guidance do not name the standard, and the National Cyber Security Bill that will transpose NIS2 is still being prepared. Customers and contracts are what ask for it. If a regulator or buyer states a requirement, follow its wording and check with your counsel.

How do INAB and the NCSC certification scheme relate to ISO 27001?

They are separate routes. INAB accredits certification bodies that issue ISO/IEC 27001 certificates today. The NCSC's Irish Cyber Security Measures Certification and its CyFun levels are described as forthcoming and do not name ISO/IEC 27001. Watch the scheme's publication before assuming that one certificate will stand in for the other.

What does DORA mean for ICT suppliers wanting ISO 27001?

A supplier whose services support a regulated financial entity is likely to meet DORA through its customer's contract. The Central Bank defines an ICT third-party service provider as an undertaking providing digital and data services through ICT systems on an ongoing basis. DORA does not require ISO/IEC 27001, but the certificate can help you evidence control, so ask each customer what it expects.

Which bodies certify ISO 27001 in Ireland?

The certificate comes from a certification body, never from Sterling. Pick one accredited by INAB or by an accreditation body in the international recognition arrangements, then read its accreditation scope to confirm ISO/IEC 27001 and your sector are covered. INAB accredits management systems certification bodies to ISO/IEC 17021-1, supplemented for information security by ISO/IEC 27006.
