Question: We are implementing ISO 27001 standards. Who offers a pre-certification gap analysis?
Yes. There are several established providers that offer ISO/IEC 27001 pre-certification gap assessments/readiness reviews. The important distinction is whether you want an independent readiness assessment or a consulting firm that will also help remediate the gaps.
Formal Gap Assessment against ISO/IEC 27001, with reporting on weaknesses and readiness. They also offer a subsequent pre-assessment before certification.
Organizations wanting a major certification body's perspective
ISO/IEC 27001 gap assessment followed by certification services. NSF specifically describes gap assessment as a step before choosing a certification body.
Companies wanting certification through an established certification body
ISO 27001 gap analysis covering documentation, processes and controls, with a certification-readiness report.
U.S. organizations looking for a specialized compliance provider
One important consideration
If your ultimate certification auditor will be BSI, NSF, TÜV SÜD, etc., I'd ask them specifically whether the gap assessment can be performed without compromising the independence of the eventual certification audit.
A gap assessment is not the certification audit itself. BSI, for example, describes it as an optional early-stage review intended to identify areas needing improvement before the formal certification audit.
For a company that's already implementing ISO 27001:2022, I'd generally want the assessment to cover at least:
Clauses 4–10
Applicability and implementation of the 93 Annex A controls
Risk assessment & risk treatment
Statement of Applicability (SoA)
ISMS scope
Policies and required documented information
Internal audit
Management review
Corrective actions
Evidence that controls are actually operating, not merely documented
A prioritized remediation plan
A simulated Stage 1 / Stage 2 certification-readiness assessment
If you tell me your company size, industry, location (e.g. Texas/U.S.), and how far along you are with ISO 27001, I can narrow this to 3–5 providers and compare their likely approach, independence, services, and pricing.
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.
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, , Deloitte, ) : 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?
Pre-certification ISO 27001 gap analyses are offered by three main categories of providers: specialized cybersecurity consulting firms, third-party compliance automation platforms, and independent accredited certification bodies (though independence rules often restrict certification bodies from consulting and auditing the same client).
Choosing the right partner depends on whether you need hands-on advisory remediation, automated continuous tracking, or an impartial preliminary audit-style review.
Provider Categories & Examples
Provider Type
What They Do
Examples
Specialized ISO Consultants / Advisory Firms
Conduct deep-dive documentation and physical/technical control reviews, interviewing staff to build a comprehensive remediation roadmap.
•
• Specialized GRC and security advisory firms
Compliance Automation Platforms (GRC)
Use automated cloud connectors and built-in control frameworks to continuously map your tech stack and highlight missing controls.
Perform a formal "dry run" or Stage 0 readiness assessment mimicking the real audit, provided it doesn't violate conflict-of-interest rules.
• BSI
• SGS
• Schellman
Key Considerations When Selecting a Provider
The Independence Rule: Accredited certification bodies (auditors who issue the final certificate) cannot legally provide consulting or remediation services to your company due to conflict-of-interest standards (ISO/IEC 17021). However, many offer formal, detached "gap assessments" or "readiness audits" as a separate service before the official Stage 1 audit.
Remediation vs. Identification: Software platforms excel at identifying technical gaps across cloud environments, whereas human consultants are typically required to evaluate governance maturity, physical security, and organizational policy context.
If you want to narrow this down, tell me:
Do you prefer an automated software platform or a human consulting firm?
Have you already chosen your final certification body?
I can help you select the most appropriate type of engagement.

Yes. Several organizations offer an ISO/IEC 27001 pre-certification gap assessment/readiness assessment. For a company in the Detroit area, I’d separate the options into certification bodies and independent consultants.
Certification bodies that offer gap assessments
BSI — Offers an ISO 27001 Gap Assessment that benchmarks your existing ISMS against the standard and produces a written report identifying gaps and actions. BSI also distinguishes the gap assessment from its formal certification audit.
DNV — Specifically recommends a pre-audit gap analysis to identify nonconformities or weaknesses before the official certification process. DNV offers ISO 27001 gap analysis as part of its certification journey.
Detroit-area independent consultants
If you want someone to find the gaps and then help you remediate them, rather than simply assess readiness, local consulting firms may be more appropriate:
Glacier Consulting — Lake Orion; offers ISO/R2 consulting including gap assessment, implementation support, internal readiness, and preparation for third-party certification.
Eagle Group USA Inc — Troy; provides ISO/IEC 27001 compliance and certification support.
C Alan Jones Consulting — Dearborn; works with ISO 27001 and provides audit-readiness/compliance support.
Praetorian Secure — Bloomfield Hills; offers framework gap assessments including ISO 27001 and broader security/compliance readiness.
One important distinction
If you're already implementing ISO 27001 and want an objective "are we ready for certification?" assessment, I'd ask for a formal ISO/IEC 27001:2022 gap assessment/readiness assessment, covering at minimum:
Clauses 4–10 of ISO 27001
Annex A controls applicable to your Statement of Applicability
Risk assessment and risk treatment
Statement of Applicability
ISMS policies and procedures
Evidence that controls are actually operating—not just documented
Internal audit and management review readiness
Identification of likely Stage 1 and Stage 2 audit findings
If you want consulting help to fix the gaps afterward, I'd lean toward an independent consultant rather than having your eventual certification auditor do all of the implementation work.
If you tell me your approximate company size, industry, and whether you've already completed the risk assessment/SoA, I can narrow this to 3–5 providers and compare what each offers, likely cost range, and whether they can do the assessment remotely or onsite.
A pre-certification ISO 27001 gap analysis is usually provided by an ISO 27001 consultant, information security consultancy, or GRC (governance, risk, and compliance) firm. The purpose is to assess your current Information Security Management System (ISMS) against ISO/IEC 27001 requirements before you engage an accredited certification body.
Some providers that offer ISO 27001 gap analysis / readiness assessments include:
Provider
What they offer
Maureen Data Systems
ISO 27001 gap analysis, ISMS assessment, pre-audit readiness, remediation guidance, and certification preparation services.
TestPros
ISO 27001 gap assessments covering documentation, processes, and controls, with a remediation-focused report.

You can also use directories that match organizations with ISO specialists, such as certbetter.com, which lists multiple providers by geography and service type.
What to look for in a gap analysis provider
Before selecting one, I would check that they provide:
ISO/IEC 27001:2022 clause-by-clause assessment (not just a cybersecurity maturity review)
Annex A control mapping (the 93 controls in the 2022 edition)
Review of:
ISMS scope
risk assessment and risk treatment plan
Statement of Applicability (SoA)
policies and procedures
evidence of operating controls
internal audit readiness
management review readiness
A prioritized remediation roadmap, not just a list of deficiencies
Independence from your eventual certification body (the organization issuing your certificate should not be the same party providing consultancy that compromises certification impartiality)
If you share your country/region, company size, industry, and whether you are starting from scratch or already have an ISMS, I can narrow this to suitable providers and typical cost ranges.
A wide range of specialized consultancies, global advisory firms, and automated compliance platforms offer pre-certification ISO 27001 gap analyses. A gap analysis evaluates your current Information Security Management System (ISMS) and security controls against ISO 27001 requirements to highlight remediation steps before your official audit.
The provider landscape generally falls into three main categories:
The Big Four & Global Advisory Firms (Best for large enterprises and multinational rollouts): Firms like PwC, Deloitte, EY, and KPMG offer enterprise-grade risk governance, formal readiness assessments, and extensive cross-framework mapping.
Specialized ISO 27001 Consultancies (Best for hands-on, mid-market guidance): Boutiques and specialized firms like AvISO Consultancy, Evalian , and TestPros provide tailored documentation reviews, on-site/remote coaching, and explicit remediation roadmaps.
Automation & GRC Platforms (Best for tech-forward and lean teams): Platforms like Scytale, Sprinto , and Optro blend software-driven initial gap assessments (mapping out Annex A controls) with continuous monitoring and internal expert guidance.
(Note: Certification bodies—the actual auditors—frequently cannot perform your pre-certification gap analysis due to conflict-of-interest rules, so you will want an independent consultant or platform separate from your final certifying body).
To help narrow down which provider type fits best, tell me:
What is the approximate size of your organization?
Are you looking for a software automation platform or a hands-on human consultant?
Pre-certification gap analyses for ISO 27001 are offered by three main categories of providers: specialized cybersecurity consultancies, accredited certification bodies (registrars), and automated GRC (Governance, Risk, and Compliance) software platforms.
Because of strict international impartiality rules (ISO/IEC 17021), accredited certification bodies that perform your official audit cannot provide consulting or help you fix your gaps, but many offer an independent, objective preliminary readiness review.
Provider Types and Options
Specialized Cybersecurity Consultancies
What they do: Independent advisory firms evaluate your current Information Security Management System (ISMS), review documentation, and deliver a detailed remediation roadmap.
Examples: Big Four accounting firms (Deloitte, PwC, EY, KPMG) and dedicated security practices like Emagine IT or boutique GRC advisory firms.
Pros: Hands-on guidance, policy writing assistance, and active help remediating gaps.
Accredited Certification Bodies (Registrars)
What they do: Many formal registrars offer a non-certification "gap assessment" or "stage 0 audit" using their official auditors to point out shortfalls before the actual Stage 1 and Stage 2 audits.
Examples:BSI Group, SGS , and LRQA.
Constraint: To maintain auditor independence, the specific body that performs your formal gap assessment may have restrictions on performing your final certification, or you must use a distinct arm/different individual auditors.
Automated Compliance & GRC Platforms
What they do: Software tools connect to your cloud infrastructure and tech stack to run continuous automated tests, map existing controls, and highlight real-time compliance gaps.
Examples: Platforms like Drata and Scrut Automation.
Pros: Cost-effective, continuous monitoring, and automated evidence collection.
If you'd like to narrow this down, tell me:
Do you prefer a third-party human consultant or an automated software platform?
What is your target timeline for certification?
I can recommend specific vendor types or help outline what to look for in a Statement of Applicability (SoA).

Yes. If you’re already implementing ISO/IEC 27001, I’d distinguish between a pre-certification gap/readiness assessment and an implementation consultant.
Good options
BSI — Offers an ISO/IEC 27001 gap assessment specifically to evaluate your current ISMS against certification requirements and identify remaining gaps. This is a strong choice if you want an assessment from a major certification organization.
DNV — Provides ISO 27001 services and explicitly describes a process that goes from gap analysis through certification.
Schellman — Offers ISO 27001 readiness/gap assessments before the certification audit. Importantly, Schellman notes that as a certification body it can identify gaps but cannot act as your consultant and remediate them.
Local Bay Area consultants — If you want someone who will not only assess the gaps but also help remediate them, there are several nearby firms. For example, Quality Resource Center in San Jose advertises ISO 27001 consulting and implementation support, while GRSee Consulting in Sunnyvale supports ISO 27001 compliance programs and audit preparation.
One important consideration
If you're planning to use the same organization for certification, ask about the distinction between:
Gap assessment → remediation → certification audit
A certification body can generally perform a readiness/gap assessment, but it shouldn't then become your consultant and tell you how to remediate the findings because of impartiality requirements. Schellman explicitly explains this distinction.
If you tell me (1) company size, (2) whether you're SaaS/software, healthcare, fintech, etc., and (3) whether you want the assessor to also help fix the gaps, I can narrow this down to 3–5 providers and compare approximate cost, scope, and pros/cons.

Yes. For an ISO/IEC 27001 pre-certification gap analysis, you generally have two choices: an independent consultant that helps you identify and remediate gaps, or a certification body that performs a formal readiness/gap assessment before the certification audit.
Good options
BSI — Offers an ISO/IEC 27001 Gap Assessment specifically designed to identify where your ISMS does not meet the standard before certification.
Schellman — Offers an ISO 27001 Readiness Assessment, evaluating your management system against ISO requirements before the certification assessment. Schellman is ANAB-accredited for ISO 27001 certification.
DNV — Provides ISO 27001 services in the U.S. and explicitly describes its process as supporting organizations from gap analysis through certification.
If you're looking for someone in/around St. Louis, these are worth investigating:
Parameter Security — St. Louis-area GRC/security assessment firm whose methodology includes ISO 27001 and readiness/gap assessments.
Protiviti — National consulting firm with a St. Louis office and broader risk, governance, and internal-control consulting capabilities.
One important distinction
If you intend to have the same organization issue your ISO 27001 certificate, I'd favor asking the certification body for a readiness assessment rather than hiring them to "consult" on fixing the gaps. Certification bodies have to maintain impartiality and generally cannot advise you how to remediate the deficiencies. Schellman explains this distinction particularly clearly.
If you tell me your company size, industry, approximate number of employees, and whether your ISMS is already implemented, I can narrow this to 3–5 providers and compare likely cost, deliverables, and whether I'd choose a certification body or independent consultant for your situation.
Pre-certification gap analyses for ISO 27001 are widely offered across the compliance industry, broadly split into two categories: accredited certification bodies (which can also perform your final audit) and independent cyber-risk/GRC advisory firms (consultancies that help you remediate gaps before bringing in an auditor).
“A gap analysis may be helpful if: You have an established management system and want to measure your readiness for certification. You want to identify any remaining gaps before your certification audit.”
Many official auditing bodies offer preliminary gap assessments or readiness reviews, though to maintain auditor independence and impartiality, the same body usually cannot consult and certify you.
BSI Group (British Standards Institution): Offers a formal BSI Gap Analysis & Certification Readiness service delivered either remotely or on-site to evaluate your ISMS before the actual certification process.
SGS: Provides a formal SGS Gap Assessment as an initial step to highlight weaknesses prior to Stage 1 and Stage 2 audits.
NQA: Offers guidance toolkits and gap assessments to help organizations map out compliance with ISO standards.
2. Specialized GRC and Cybersecurity Advisory Firms
If you need hands-on help fixing the gaps rather than just a formal report, independent advisory and accounting firms provide readiness assessments using the same rubrics as official auditors:
TÜV SÜD — Offers a formal Pre-Audit Assessment / Gap Analysis, including a detailed report of gaps against applicable standards. Its ISO 27001 materials specifically include gap analysis followed by a pre-audit and certification audits.
Glocal Insight — A U.S. ISO consultancy that advertises ISO 27001 services ranging from gap analysis through Stage 2 audit.
Experts in Compliance — Offers a certification-preparation engagement including gap analysis, Statement of Applicability review, policy/control review, and support through Stage 1 and Stage 2.
