    Why choose CyberWave GRC

    From gap assessment to audit support

    1. Gap assessment and ISMS scope

    We review your existing security practices and define the information security management system scope with your team. Record the relevant business activities, locations, systems and responsibilities rather than copying another organization’s scope.

    2. Risk assessment and implementation

    We help develop the risk assessment, treatment plan, policies and Statement of Applicability. Control selection must reflect your risks and justified requirements; the evidence should explain why each applicable control is used.

    3. Internal audit and readiness

    We support internal audit, management review preparation and tracking of corrective actions. The aim is to check the implemented ISMS before the certification audit, not simply complete a set of documents.

    4. Certification audit support

    We help organize evidence and coordinate requests for the certification body’s Stage 1 and Stage 2 audits. Your organization owns its ISMS, and the certification body remains responsible for the independent decision.

    VAPT: bundled or standalone

    We offer vulnerability assessment and penetration testing both within a compliance engagement and separately. Agree the assets, testing approach, deliverables and remediation or retesting responsibilities in the proposal. Bundled availability does not mean every project includes the same testing package.

    Our VAPT partner is CERT-In empanelled. That empanelment belongs to the partner, not CyberWave GRC. If empanelment is part of your procurement requirement, confirm the performing entity and current scope before commissioning the work.

    Common control frameworks: a coordinated program

    When your business needs ISO 27001 alongside other frameworks, separate policy sets and disconnected evidence requests can make the program harder to manage. We map overlapping requirements to a common control framework with owners, records and framework-specific references.

    For example, access management, incident handling and vendor reviews can be mapped across relevant requirements. Evidence is reused only where it meets each requirement. The common framework does not remove legal duties, guarantee an assessment result or replace a separate audit or certification decision.

    An ISMS that fits your organization

    The ISMS should reflect the actual scope and responsibilities of your business. For a small organization, that may mean a focused set of owners and systems. A large organization may need coordination across business units, locations and shared services. Neither should receive an unrelated template scope.

    VAPT findings can inform risk treatment and technical remediation. A penetration test does not replace the ISMS, internal audit, management review or independent certification audit.

    Who this approach is for

    CyberWave GRC supports all industries and small, medium and large organizations. We do not reserve implementation help or coordinated audit support for one company size. The applicable ISO 27001 requirements and the actual environment determine the work.

    Bring your customer requirements, existing controls, relevant systems and any other frameworks to the first discussion. We can use those inputs to agree a connected scope rather than choosing a package purely by employee count.

    Questions to settle before you start

    • What is the agreed scope, and who owns the decisions?
    • Which gap assessment and implementation deliverables will we receive?
    • What evidence will our team need to maintain?
    • Is VAPT bundled or separate, and what does its scope include?
    • Which overlapping controls will be mapped to other frameworks?
    • Who performs the independent assessment and issues the final output?
    • Which fees and activities are included or excluded?

    Independent roles and responsibilities

    An accredited certification body conducts the certification audits and decides whether to issue the ISO 27001 certificate. CyberWave GRC supports preparation, implementation and audit coordination; we do not issue the certificate or guarantee the certification decision.

    What Sets the Best ISO 27001 Consultants Apart

    The best ISO 27001 consultants don't hand you a template ISMS and walk away. They help you set a scope that matches your business, build a risk assessment that reflects your real risks, and stay with you through the internal audit and the certification body's Stage 1 and Stage 2 audits. When you compare proposals, ask who owns each deliverable, whether VAPT is bundled or separate, and which controls can be reused for other frameworks. That's how we work at CyberWave GRC, for small teams and large organizations alike. One thing to remember: the certificate comes from an accredited certification body, not from us.

    Frequently asked questions

    Typically a few months, depending on scope, company size and how mature your controls are. The work covers gap assessment, ISMS implementation, internal audit and management review before the two-stage certification audit.

    Cost depends on scope, number of locations and staff, and existing controls. Ask for a fixed-scope proposal that separates consulting fees from the certification body's audit fees.
