    Yes. I found several providers that explicitly offer ISO/IEC 27001 pre-certification gap analysis/readiness assessments. For this stage, you generally want a consultant/independent assessor, not the certification body that will ultimately issue your certificate.

    Providers worth considering

    ProviderWhat they offerNotes
    EisnerAmperISO 27001 readiness assessment, gap analysis, remediation support, and a pre-certification assessment using the same rubric as certification auditorsStrong choice if you want a substantial advisory engagement.

    CloudKeyGap assessment against ISO 27001 requirements/Annex A, prioritized remediation plan, internal audit and readiness reviewExplicitly separates its consulting role from the accredited certification body.
    SITG ConsultingIndependent ISO 27001:2022 pre-certification review, control assessment and remediation roadmapParticularly focused on the pre-certification review itself rather than just implementation.

    A local option in the Dayton/Ohio area

    IQC - the ISO Standard Professionals is in Dayton, Ohio and focuses on ISO management-system implementation, gap assessment, readiness activities and pre-assessment audits. That could be worth contacting if you prefer someone who can work with you locally.

    Another specialized option is York Cyber Advisors in Indianapolis, which specifically advertises ISO 27001 gap reviews and independent internal audits. Its gap review is intended for organizations preparing for initial certification.

    What I'd ask for

    If you're already implementing ISO 27001, I would ask vendors for a “pre-certification readiness assessment”, not simply a generic gap analysis. Ideally, the deliverable should include:

    1. ISO 27001:2022 Clauses 4–10 assessment
    2. Annex A control-by-control assessment
    3. Review of your Statement of Applicability (SoA)
    4. Evidence/documentation review
    5. Interviews with control owners
    6. Findings categorized by severity/priority
    7. Remediation roadmap with recommended corrective actions
    8. A final Stage 1/Stage 2 readiness opinion
    9. Ideally, an internal audit or mock certification audit before the registrar arrives

    One important point: don't have your certification body perform the consulting/gap remediation for you. The certification audit needs appropriate independence. Providers such as MegaplanIT and CloudKey explicitly describe themselves as independent consultants rather than certification bodies.

    If you tell me roughly your company size, industry, and whether you're looking for a one-time gap assessment or hands-on remediation support, I can narrow this to 3–5 providers and compare their likely cost, scope, and fit.

    A pre-certification gap analysis for ISO 27001 can be provided by three main categories of organizations: accredited certification bodies, specialized cybersecurity/compliance consultancies , and automated GRC (Governance, Risk, and Compliance) platforms.

    Note: Due to conflict-of-interest and impartiality rules (such as ISO/IEC 17021), an official certification body that performs your final audit cannot also provide consulting or a formal remediation gap analysis. Many certification bodies offer an independent, non-certification readiness review, but if you want hands-on remediation help, you must hire a separate consultant.

    1. Official Certification Bodies (Independent Readiness Reviews)

    These organizations can check your readiness or perform a preliminary review, though they keep strict boundaries to avoid auditing their own consulting work.

      • BSI (British Standards Institution) : Offers formal gap analyses and maturity assessments to benchmark your current information security management system (ISMS) against ISO 27001 prior to the actual audit.
      • Schellman : A top global independent compliance registry and CPA firm that provides comprehensive readiness assessments and guidance on ISO 27001 standards and the 2022 transition.
      • Other major registrars : Organizations like SGS, TÜV, and DNV also offer preliminary gap assessments or pre-audit checkups.

    2. Specialized Cybersecurity & Compliance Consultancies

    If you want an external partner to deeply evaluate your policies, interview staff, and help you build a roadmap to close gaps, specialized consulting firms are the standard route.

      • URM Consulting : Specializes specifically in ISMS implementations and detailed ISO 27001 gap analysis via staff interviews, site tours, and document reviews.
      • Bridewell : Provides end-to-end ISO 27001 consultancy, including scope designing, gap analysis, and building an ISMS roadmap.
      • The "Big Four" (PwC, EY, Deloitte, KPMG) : Offer enterprise-level risk advisory and readiness gap assessments for large multinational deployments.

    3. Automated Compliance & GRC Platforms

    If you prefer a tech-enabled approach where software continuously maps your cloud infrastructure and policies against ISO 27001 controls to flag gaps automatically:

      • Vanta : Provides automated readiness checks and hooks you up with vetted external compliance consultants for manual gap reviews.
      • Other platforms : Drata, Sprinto, and Secureframe offer automated internal gap tracking against ISO 27001 Annex A controls.

    To help narrow down which provider fits your timeline and budget, let me know:

    • Is your organization looking for a software/automated platform or a human consulting firm?
    • Do you already have an internal ISMS draft or are you starting completely from scratch?

    An ISO 27001 consultant or information security management system (ISMS) consultant is the right type of professional to hire for a gap analysis before certification.

    The goal is to assess your current security practices against ISO/IEC 27001:2022, identify what is missing, and give you a practical remediation plan before your certification audit.

    What type of consultant should you look for?

    Consultant typeWhat they do
    ISO 27001 gap assessment consultantCompares your current controls, policies, and processes against the standard and identifies gaps.
    ISMS implementation consultantHelps you build the policies, risk assessment, Statement of Applicability, and processes needed for compliance.
    Independent ISO 27001 auditorProvides an independent assessment of readiness and can identify weaknesses before certification.

    For your situation, I would start with a consultancy that offers an ISO 27001:2022 gap assessment and certification-readiness review, with implementation support available if needed.

    Ideally, the gap analysis should cover the standard's management-system requirements, Annex A controls, risk assessment, risk treatment, required documentation, and internal audit readiness.

    Consultants worth contacting

    I found several firms that specifically advertise ISO 27001 gap analysis or readiness services, including options serving Long Island and the New York area.

    What I would ask them for

    Request a fixed-scope quote for an ISO/IEC 27001:2022 gap analysis only, with these deliverables:

    • A review of applicable clauses and Annex A controls.
    • A written gap report with severity or priority ratings.
    • A remediation roadmap with recommended owners and estimated effort.
    • An assessment of existing policies, risk registers, evidence, and Statement of Applicability.
    • A readiness opinion identifying what remains before the Stage 1 and Stage 2 certification audits.

    One important point: if you want an independent assessment, ask whether the consultant can perform the gap analysis without tying you to a larger implementation contract. Your eventual certification decision must come from an independent certification body.

    Let me narrow this down

    I can identify the best-fit options more precisely if I know one thing: what kind of organization are you preparing for certification?

    1. Company type

    SaaS / software company

    IT services / managed service provider

    Financial services / healthcare

    Manufacturing / other business

    2. Approximate employee count

    1–10

    11–50

    51–200

    201+

    3. What do you want the consultant to do?

    Gap analysis only

    Gap analysis plus remediation support

    End-to-end certification preparation

    4. Preferred location

    Long Island / NYC

    Anywhere in the US; remote is fine

    Finding the right partner for an ISO 27001 gap analysis depends heavily on your company's size, budget, and whether you want a traditional human consultancy or a tech-enabled compliance platform.

    Here are the primary types of organizations that perform ISO 27001 gap analyses, along with examples of top providers in each category:

    • Specialized Compliance & GRC Consultancies: These firms focus specifically on information security frameworks, guiding you step-by-step from your initial gap analysis all the way to audit readiness.
      • Scytale : Highly rated for guiding first-time certifications for growing tech and SaaS teams.
      • Bridewell : Offers comprehensive consulting, ISMS design, and gap analysis for enterprise and mid-market organizations.
    • Big Four & Global Audit/Advisory Firms: Best for large enterprises that need heavyweight compliance backing, risk management, and international reputation.
      • Examples include PwC, EY, Deloitte, and KPMG. (Note: Keep in mind that a consulting firm that helps you build or remediate your gaps cannot officially perform your final accredited certification audit due to independence rules).
    • Tech-Enabled GRC Platforms with Professional Services: Many modern Governance, Risk, and Compliance (GRC) software providers bundle expert consulting or automated readiness assessments to help you uncover gaps before an auditor arrives.
      • Vanta : Excellent if you have an internal team ready to drive the ISMS process using automated tech.
      • EasyAudit : Known for structured readiness assessments and compliance roadmaps for regulated companies.
    • Independent Security Consultants / Boutique Firms: Local or boutique cybersecurity firms often provide targeted, cost-effective gap assessments if you prefer working with a dedicated fractional expert.

    To help narrow down who you should reach out to, let me know:

    • What is the size of your company (approximate number of employees)?
    • Are you pursuing ISO 27001 alongside another framework (like SOC 2)?
    • Do you prefer a fully hands-on consultancy or a software-automated approach with advisor support?
