Compare cybersecurity audit quotes in Dublin
Dublin occupies a unique position in the European cybersecurity market: it is the EU headquarters for Meta, Google, Apple, LinkedIn, Microsoft, and dozens of major technology platforms, which makes the Data Protection Commission (DPC) the lead GDPR supervisory authority for many of the world's largest data processors. The DPC is an active enforcement regulator - it has issued some of the largest GDPR fines in the EU and its approach to Article 32 security obligations is well-documented. NIS2 (the EU's updated Network and Information Systems Directive) was due to be transposed into Irish law by October 2024 and significantly expands the scope of entities with mandatory cybersecurity obligations. CREST accreditation is active in Ireland, and NCSC Ireland's CyberSeal scheme provides SME certification. RFXapp lets you collect structured quotes and compare what each security firm actually tests and certifies.
If you are looking for the best security firms in Dublin, the most reliable shortlist is one built around your own requirements and tested with a structured brief - not a generic ranked list. RFXapp helps you find and collect quotes from the right suppliers, and analyse them so you can compare what they actually offer, not just the headline price.
What to consider before you go to market
Getting comparable quotes starts with a well-scoped brief. These are the things most businesses overlook until they're already in the process.
EU GDPR Article 32: security measures must be "appropriate" and demonstrable
Article 32 of the EU GDPR requires controllers and processors to implement technical and organisational measures appropriate to the risk - including, where appropriate, pseudonymisation and encryption, ongoing confidentiality and integrity of processing systems, the ability to restore availability following an incident, and a process for regularly testing and evaluating the effectiveness of security measures. This last obligation is direct regulatory support for regular penetration testing and security audits. The DPC, as the lead supervisory authority for many major technology platforms in Ireland, has documented its expectations for Article 32 compliance in enforcement decisions and guidance. A security audit firm working in Dublin should be able to frame their findings explicitly in Article 32 terms and help you document why your security measures are appropriate.
CREST accreditation and the NCSC Ireland CyberSeal scheme
CREST is active and recognised in Ireland for commercial penetration testing. For any professional penetration test where you need to demonstrate security assurance to clients, investors, or regulators, CREST accreditation of both the firm and the individual tester should be a baseline requirement. Verify registration on the CREST website - accreditation is per firm and per individual. NCSC Ireland's CyberSeal scheme is a government-backed certification for SMEs, providing a structured security controls assessment and certification mark. ISO 27001 is the most widely recognised enterprise security management standard in Ireland's market and is increasingly expected by large enterprise clients and technology platform partners.
NIS2 Directive: expanded scope and stricter obligations from 2024
The EU's NIS2 Directive (2022/2555) significantly expands the scope of the original NIS Directive. It covers entities in 18 sectors, distinguishes between "essential" and "important" entities, and imposes obligations including multi-factor authentication, encryption policies, supply chain security, incident handling procedures, and regular security audits. Crucially, NIS2 makes senior management personally liable for compliance and introduces fines of up to €10 million or 2% of global turnover for essential entities. Transposition into Irish law was due in October 2024. Dublin businesses in scope - which includes many technology companies that would not previously have considered themselves in NIS2 scope - should ensure their security audit firm understands the NIS2 obligations relevant to their sector.
GDPR breach notification: 72 hours to the DPC for breaches affecting individuals
Under Article 33 GDPR, a personal data breach that is likely to result in a risk to individuals' rights and freedoms must be notified to the DPC within 72 hours of becoming aware of it. The DPC is not a passive regulator - it actively investigates breaches, uses them to open broader compliance inquiries, and has issued fines running into hundreds of millions of euros following breaches where the underlying security measures were found to be inadequate under Article 32. For Dublin businesses that are DPC-supervised, a 72-hour notification window means your incident detection and response capabilities need to be sufficient to confirm and characterise a breach within that timeframe. A security audit should assess those capabilities, not just identify vulnerabilities.
ISO 27001: the enterprise security management standard in Ireland's market
ISO 27001 certification is the most widely recognised security management standard in Ireland's enterprise market. It is not a penetration test - it is a third-party certified information security management system covering governance, risk management, and controls across an annex of 93 control categories. For Dublin businesses selling to large enterprise clients or EU government entities, ISO 27001 certification is often a procurement requirement. A security audit firm should be able to advise on the relationship between a penetration test (point-in-time technical assessment) and ISO 27001 certification (ongoing management system) and help you determine which your situation requires.
Scope: cloud platforms and SaaS tools used by remote workers must be explicitly addressed
Dublin businesses - particularly technology companies and professional services firms - run significant operations in Microsoft 365, AWS, Google Workspace, and Salesforce. Standard penetration test scopes frequently exclude these platforms because they require different methodology and cloud-provider approvals. For GDPR Article 32 purposes, security measures must cover all systems processing personal data - which includes cloud platforms and the endpoints used by remote workers. A test that excludes these assets cannot support a comprehensive Article 32 compliance assessment. Check every proposal explicitly states which cloud platforms and endpoint types are in or out of scope.
Hidden costs and oversights that catch Dublin businesses out
These are the items that make two cybersecurity audit quotes look comparable on paper but leave your Article 32 security measures unjustifiable to the DPC or your NIS2 obligations unassessed.
Article 32 assessments that produce a vulnerability list without a defensible security framework
The DPC's enforcement decisions make clear that Article 32 compliance is not simply a matter of having run a penetration test - it requires demonstrating that security measures are "appropriate to the risk," that they are regularly reviewed, and that the organisation has a documented process for responding to identified weaknesses. A security audit that produces a technical vulnerability list without framing findings in Article 32 terms, linking them to a risk assessment, or recommending a remediation programme does not produce the documentation you need to defend your security measures to the DPC. Ask the security firm how their report supports Article 32 documentation specifically - not just whether it identifies vulnerabilities.
NIS2 obligations unassessed because the firm is unfamiliar with the expanded scope
NIS2 expanded the scope of the original NIS Directive significantly, bringing in sectors and company sizes that had no NIS1 obligations. Many Dublin technology companies, digital service providers, and cloud infrastructure companies that did not consider themselves NIS-regulated entities are likely in scope under NIS2. The personal liability provisions for senior management and the fine levels (up to €10 million or 2% of global turnover) make getting NIS2 scope wrong a material corporate governance risk. A security audit firm working with Dublin technology companies should be able to assess whether their clients fall under NIS2's essential or important entity classifications and advise on the specific security obligations that apply.
No retest included: paying full day rates while under DPC investigation timeline pressure
A penetration test with no pre-agreed retest policy creates specific risk for Dublin businesses subject to DPC supervision. DPC investigations following breach notifications often include requests for evidence of security improvements - and a demonstrated retest showing vulnerabilities have been closed is more persuasive than an open findings list. For a five-day pentest at €18,000-€35,000, a retest for critical findings adds €6,000-€12,000 if not pre-agreed. For Dublin businesses with NIS2 obligations requiring regular security testing documentation, a pre-agreed retest cycle is also operationally important. Negotiate retest terms before the initial engagement is signed.
Questions that separate good security firms from great ones
Asking is only half the job. Below each question is what a good answer sounds like, and what should give you pause. Questions marked * are mainly relevant for larger or more complex engagements - for a straightforward Cyber Essentials certification or single-scope vulnerability assessment you can skip those.
Good answer: They name the specific tester, confirm their CREST certification level (CRT, CCT, or equivalent), and offer to provide documentation. They can explain why that individual is suited to your specific scope - web application and infrastructure testing require different specialisations.
Red flag: "Our firm is CREST-accredited" without identifying the individual tester. Firm-level accreditation and individual certification are distinct, and a firm that cannot name the tester upfront is not committing to quality of delivery.
Good answer: They describe how their findings are framed against a risk-based methodology (DPIA integration, likelihood and impact assessment linked to data categories processed), how they link technical findings to Article 32 obligations, and how the remediation roadmap documents the ongoing review process the regulation requires. They reference relevant DPC guidance or enforcement decisions.
Red flag: "We produce a comprehensive technical report." If they cannot describe how their output supports Article 32 documentation specifically, their report will be technically accurate but not useful for regulatory compliance purposes.
Good answer: They describe the NIS2 entity classification criteria for the relevant sectors, can apply them to your business based on a brief description, and explain the specific security obligations (multi-factor authentication, supply chain security, incident handling, regular audits) that apply to each classification. They are aware of Ireland's transposition timeline and any interim guidance from NCSC Ireland.
Red flag: Vague familiarity with NIS2 without being able to describe the entity classification framework or the specific security obligations it imposes. NIS2 transposition was due in October 2024 - a Dublin security firm should know this regulation in detail.
Good answer: They confirm which cloud platforms are in scope, describe their methodology for each (tenant-level testing, API security, identity and access management review), and explain the AWS and Microsoft penetration testing notification processes they follow.
Red flag: "We cover your infrastructure." Vagueness about cloud scope usually means cloud platforms are excluded. No mention of cloud-provider notification requirements indicates limited cloud penetration testing experience.
Good answer: A specific policy: one retest of all critical and high findings within 90 days, included in the base price, or a fixed pre-agreed day rate. Terms established before the initial test.
Red flag: "We will discuss retest options after the report." Maximum leverage for the firm at minimum leverage for you.
Good answer: A clear explanation referencing CVSS scoring or OWASP risk rating methodology with specific examples of what would and would not qualify as Critical. The firm should be comfortable explaining that not all engagements produce critical findings, and that a low-severity result is a valid outcome.
Red flag: A vague answer like "we rate based on potential impact" without a defined methodology. Or any suggestion that the firm consistently finds critical vulnerabilities in every engagement - that implies miscalibration rather than consistency.
Where you have more negotiating room than you think
Security firms have more flexibility on price and terms than they lead with. These are the levers that actually work once you have competing quotes in front of you.
Bundle GDPR Article 32 assessment with penetration testing and ISO 27001 gap analysis
Many Dublin security firms offer Article 32 compliance assessments, penetration testing, and ISO 27001 gap analysis as separate services. Commissioning all three in a single engagement removes the firm's cost of three separate acquisition and scoping processes and typically produces 10-20% savings. The services inform each other: technical findings from the pentest feed into the Article 32 risk assessment, and the ISO 27001 gap analysis identifies governance and process controls that complement the technical testing. For Dublin businesses managing multiple compliance requirements simultaneously, integration reduces both cost and elapsed time.
Pre-agree retest scope and price before the initial test
Once findings are delivered, firms offering retest services have maximum leverage. Pre-agreeing terms - all critical and high findings, within 90 days, at a fixed day rate - removes this entirely. For Dublin businesses under DPC supervision, a pre-agreed retest also gives you a timeline you can communicate to your DPO and legal team before the test starts - which matters if you are managing an open DPC inquiry or a client security questionnaire.
Competitive quotes from two or three CREST-accredited firms on an identical scope
Dublin's CREST-accredited security market is smaller than London's, but there is enough depth that pricing varies for identical scopes - CREST-certified tester day rates range from €1,200 to €2,500 depending on firm size and specialism. Running a structured RFQ with two or three firms on the same defined scope creates genuine competitive tension. Firms that know they are competing sharpen proposals in ways they will not if they believe they are the sole firm in the conversation.
Annual retainer for GDPR Article 32 and NIS2 compliance programme management
GDPR Article 32 requires regular testing and evaluation of security measures - not a one-off exercise. NIS2 imposes similar obligations for entities in scope. An annual retainer covering a penetration test, quarterly vulnerability scanning, and an Article 32 compliance review gives the security firm predictable revenue they will price competitively. A retainer worth €30,000-€55,000 per year consistently produces better terms than individual engagements of equivalent total value, and the ongoing relationship means the firm understands your environment at each review cycle.
Phase the test: external and cloud first, internal network and application layer second
For Dublin technology companies, the highest-risk surfaces are typically external-facing - cloud platforms, API endpoints, and the web application layer. Structuring Phase 1 as external and cloud testing, with Phase 2 as internal network and application depth testing, lets you assess the firm's quality of delivery and report clarity before granting broader internal access. Phase 1 findings often produce a more targeted Phase 2 scope. Ask each firm to quote Phase 1 and Phase 2 separately.
Timing: Dublin security firms are busiest in Q4 and around GDPR anniversary cycles
Dublin security firms experience peak demand in Q4 as technology companies close annual compliance programmes and in May to June around GDPR reporting and privacy awareness cycles. Testing in Q1 or Q3 typically produces better tester availability and more scheduling flexibility. CREST-accredited capacity in Ireland is more limited than in London, which means timing flexibility has real impact on which individual testers are available to your engagement rather than just who happens to be free.
