ISMS Manager

Also known as: Information Security Manager, ISMS-Manager (ISB), ISO 27001 Information Security Manager
Simply put

An ISMS Manager is the person responsible for setting up, running, and improving an organization's Information Security Management System (ISMS), the framework used to manage, monitor, and improve information security practices in one place. This typically includes developing security policies that define how information should be protected and overseeing the day-to-day operation of security management. The role is commonly associated with implementing and maintaining an ISO 27001-aligned management system.

Formal definition

The ISMS Manager is the individual accountable for implementing, managing, and maintaining an organization's Information Security Management System, typically in alignment with ISO/IEC 27001. Responsibilities generally include establishing and operating the centrally managed ISMS framework used to manage, monitor, review, and improve information security practices; creating security policies that define how information is to be protected; and driving continual improvement of the ISMS. The scope and exact duties of the role vary by organization, and the position may be developed through structured competence pathways and training covering ISO 27001 and related information security management standards. Note that the ISMS Manager role concerns the ISO 27001 management-system context and is distinct from roles tied to a SOC 2 examination, which is an attestation performed under the AICPA framework rather than a certifiable management system.

Why it matters

The ISMS Manager sits at the operational center of an organization's information security governance. Because ISO/IEC 27001 requires an Information Security Management System to be established, operated, monitored, reviewed, and continually improved, someone must own that lifecycle in practice. The ISMS Manager typically fills this role, giving the organization a single point of accountability for the centrally managed framework that keeps security practices coordinated rather than fragmented across teams. Without a clearly designated owner, policies drift, reviews lapse, and the management system loses the coherence that certification against clauses 4 through 10 depends on.

The role also matters because the ISMS is meant to be a living system, not a one-time project. The ISMS Manager drives the continual improvement expectations built into the standard, ensuring that security policies, which define how information is to be protected, stay current as risks, scope, and the business change. This ongoing stewardship is what allows an organization to demonstrate to an accredited certification body that its ISMS operates consistently over time, within its defined scope.

It is worth being precise about the boundaries of this role. The ISMS Manager's remit concerns the ISO 27001 management-system context; it does not automatically extend to a SOC 2 examination, which is an attestation performed by a licensed CPA firm under the AICPA framework rather than a certifiable management system. An organization pursuing both frameworks may map responsibilities across them, but satisfying ISO 27001 duties does not by itself satisfy SOC 2 requirements, and vice versa.

Who it's relevant to

GRC and Compliance Managers
Those responsible for coordinating an organization's ISO 27001 program rely on a designated ISMS Manager to own the framework, maintain security policies, and drive the continual improvement that certification against the ISMS requirements depends on.
Security Engineers and Practitioners
Technical staff implementing controls benefit from a clear management-system owner who translates policy into day-to-day operational expectations and ensures security practices are managed and monitored in one coordinated place rather than in silos.
Professionals Pursuing the Role
Individuals building toward an ISMS Manager position often develop competence through structured training and learning pathways covering ISO 27001 and related standards, progressing from foundational concepts to more advanced management techniques.
Executives and ISMS Sponsors
Leadership accountable for the ISMS scope relies on the ISMS Manager as the single point of accountability for operating and improving the system, while recognizing that certification covers only the defined scope and does not extend automatically to other frameworks such as SOC 2.

Inside ISMS Manager

ISMS Ownership and Coordination
The ISMS Manager is typically responsible for coordinating the day-to-day operation of the Information Security Management System established under ISO/IEC 27001 clauses 4 through 10, ensuring the management system requirements are implemented and maintained across the defined scope.
Statement of Applicability (SoA) Maintenance
This role commonly oversees the Statement of Applicability, through which Annex A reference controls are selected, justified, and their inclusion or exclusion documented based on the outcomes of the risk assessment. The specific control set depends on the version cited, as Annex A was restructured in the 2022 revision (93 controls in four themes) from the 2013 version (114 controls).
Risk Assessment and Treatment Facilitation
The ISMS Manager typically facilitates the information security risk assessment and risk treatment process, which informs which Annex A controls are applied. In most engagements this involves coordinating with risk owners rather than unilaterally determining risk decisions.
Management Review and Continual Improvement
The role generally supports the management review process, monitoring, measurement, internal audit coordination, and corrective actions that drive continual improvement of the ISMS, as required by the clause 4 through 10 requirements.
Certification Liaison
The ISMS Manager often serves as the primary liaison with the accredited certification body during certification and surveillance audits, since ISO/IEC 27001 results in a certification issued against the management system standard rather than an attestation report.

Common questions

Answers to the questions practitioners most commonly ask about ISMS Manager.

Is the ISMS Manager the person who issues the ISO 27001 certificate?
No. The ISMS Manager is an internal role responsible for coordinating and maintaining the information security management system. The certificate itself is issued by an accredited certification body following a successful audit, not by anyone inside the organization. The ISMS Manager typically prepares the organization for that external audit and acts as a point of contact, but has no authority to grant certification.
Does having an ISMS Manager mean the organization is automatically ISO 27001 certified?
No. Appointing an ISMS Manager is an organizational decision that supports building and running the management system described in ISO 27001 clauses 4 through 10, but it does not by itself confer certification. Certification depends on an accredited certification body assessing the defined scope of the ISMS, and the outcome varies based on the audit, the scope, and the evidence presented.
What are the typical day-to-day responsibilities of an ISMS Manager?
In most implementations the ISMS Manager coordinates the ongoing operation of the management system, which can include maintaining documentation, supporting the risk assessment process, helping keep the Statement of Applicability current, tracking corrective actions, and preparing for internal and external audits. The exact scope of duties varies by organization and how the role is defined.
How does the ISMS Manager relate to the risk assessment and Statement of Applicability?
The ISMS Manager often facilitates the risk assessment process and helps ensure that the selection of Annex A reference controls is documented in the Statement of Applicability and traceable to identified risks. Whether the ISMS Manager owns these activities directly or coordinates contributions from others depends on how responsibilities are allocated within the organization.
How does the ISMS Manager support an external certification audit?
The ISMS Manager typically serves as a primary liaison with the certification body, helping to organize evidence covering clauses 4 through 10 and the applicable Annex A controls within the defined scope of the ISMS. Depending on the engagement, this can involve scheduling, coordinating interviews, and managing responses to any findings, though the audit outcome is determined by the certification body.
Does the ISMS Manager role overlap with responsibilities relevant to a SOC 2 engagement?
There can be practical overlap, since evidence and controls maintained for an ISMS may partially map to the Trust Services Criteria used in a SOC 2 examination. However, mapping between the two frameworks is partial, and satisfying ISO 27001 requirements does not automatically satisfy SOC 2, which is an attestation examination performed by a licensed CPA firm. Any overlap in duties depends on how the organization structures its compliance functions.

Common misconceptions

The ISMS Manager produces or manages a SOC 2 report as part of the ISO 27001 role.
ISO/IEC 27001 leads to a certification issued by an accredited certification body, not to an attestation report. A SOC 2 report is a separate deliverable produced by a licensed CPA firm under the AICPA SSAE 18 standard. Managing one does not equate to managing the other, and the two frameworks map only partially.
The ISMS Manager must implement every Annex A control.
Annex A controls are reference controls selected through the Statement of Applicability and informed by the risk assessment. Depending on scope and risk decisions, controls may be justified as excluded. The certifiable requirements themselves reside in clauses 4 through 10, not in Annex A.
An ISO 27001 certificate managed by the ISMS Manager guarantees the organization is free from breaches across all systems.
An ISO 27001 certificate covers only the defined scope of the ISMS. It attests that the management system meets the standard's requirements within that scope and does not guarantee freedom from security incidents or cover systems outside the declared boundary.

Best practices

Maintain the Statement of Applicability as a living document, ensuring each Annex A control inclusion or exclusion is justified and traceable to the risk assessment, and specify which version of the standard (2013 or 2022) governs the control set in use.
Clearly define and document the ISMS scope so that certification boundaries are unambiguous and stakeholders understand what is and is not covered by the eventual certificate.
Coordinate risk assessments with designated risk owners rather than making risk treatment decisions in isolation, keeping evidence of the process aligned with clauses 4 through 10.
Establish a regular cadence of internal audits, management reviews, and corrective actions to demonstrate continual improvement to the certification body during surveillance audits.
When the organization also pursues SOC 2, treat the two efforts as distinct but partially mappable, since satisfying ISO 27001 requirements does not automatically satisfy the SOC 2 Trust Services Criteria.
Keep clear records distinguishing certification-related evidence (ISO 27001) from any attestation-related evidence (SOC 2), and avoid describing ISO outcomes as reports or SOC outcomes as certifications in internal and external communications.
