Businesses expanding operations in South Korea face a unique challenge: they have to navigate both international security standards and country-specific regulatory requirements. Most organizations must engage with ISMS or ISMS-P, South Korea's national certifications for information security and personal information protection.
For organizations already aligned with ISO 27001 and ISO 27701, the ISMS-P framework may look familiar at first glance. The challenge is understanding where the similarities end, where ISMS-P introduces additional expectations, and how to address them.
This guide explains what ISMS-P entails, how it compares to ISO standards, and how you can use your existing controls to streamline compliance.
What is ISMS-P?
ISMS-P is South Korea’s primary certification for information security and personal information protection. It consolidates two existing programs—Information Security Management System (ISMS) and Personal Information Management System (PIMS)—into a single assessment and review framework, allowing organizations to demonstrate compliance with both through a single certificate.
The framework is jointly administered by the Ministry of Science and ICT (MSIT) and the Personal Information Protection Commission (PIPC), while the Korea Internet & Security Agency (KISA) operates the program, maintains the certification criteria, and issues certificates through the certification committee it convenes.
For years, only the ISMS component of the framework has been mandatory for organizations that meet specific thresholds, including at least KRW 10 billion in prior-year information and communications service (ICS) sales or an average of 1 million or more daily users in the preceding fiscal year, as well as certain categories of operators: telecom carriers and ISPs, Internet Data Center (IDC) operators, upper-tier general (tertiary) hospitals, and universities with 10,000+ enrolled students. The PIMS component and the integrated ISMS-P certificate remained voluntary—until the latest legislative amendments expanded the mandatory scope.
How the ISMS-P scope is changing in 2026–2027
Following amendments to South Korea’s Personal Information Protection Act (PIPA), the mandatory scope of ISMS-P will expand from July 1, 2027, to cover the full ISMS-P while adding new coverage categories, including:
- Mobile telecom carriers (tier changes, already included)
- Major public system operators
- Identity verification service providers
- Large-scale personal information controllers (based on volume and revenue thresholds)
The changes also replace the previous one-size-fits-all certification model with three tiers—Enhanced , Standard, and Simplified—based on public impact. For example, high-risk operators such as telecom carriers, ISPs, and large IT service providers will likely have to meet the Enhanced tier, which requires more rigorous technical controls, continuous monitoring, and investment in automation.
The reforms also change how organizations are assessed. Instead of paper-based documentation reviews, assessments are shifting to site-based technical audits with on-site verification, real-time demonstration, penetration testing, and vulnerability assessments.
While the ISMS-P certification itself serves as evidence of good-faith efforts to secure information, organizations required to maintain certification can face administrative fines of up to KRW 30 million (approximately USD 23,000), imposed annually until certification is obtained, alongside corrective orders. Notably, a company can face more stringent legal investigations and aggressive audits if it suffers a breach.
Fortunately, organizations with mature ISO 27001 and ISO 27701 programs won’t have to start from scratch.

How ISMS-P controls map to ISO standards in 4 domains
ISMS-P consists of 102 certification criteria covering information security and personal information protection—80 covering the information security management system and 22 covering personal information processing. KISA groups these into three areas: establishment and operation of the management system, requirements for protection measures, and criteria for each stage of personal information processing.
To make ISMS-P requirements easier to compare with international standards like ISO 27001 and ISO 27701, we’ll group them into four buckets:
- Governance and risk management controls
- Information security controls
- Personal information protection
- Monitoring and continuous improvement
“The strongest overlap is structural rather than control by control. ISMS-P shares the same management system DNA as ISO 27001, including scope, leadership accountability, risk assessment, control operation, monitoring, and continual improvement, because it was modeled on the ISO standards to begin with. For organizations that already have a mature ISO-based ISMS, that’s the layer I’d expect to carry over most cleanly.
A team that already runs a mature ISMS isn’t rebuilding the governance engine, only adapting it. Where I’d set expectations carefully is that the overlap is real at the management system level, but much thinner at the legal detail level, so the management framework transfers in a way the Korea-specific requirements won’t.”

1. Governance and risk management controls
These controls require organizations to establish formal governance structures for managing security and privacy risks. To comply, you must define:
- Ownership and accountability
- Risk assessment procedures
- Remediation processes
Governance also extends to leadership. Management should oversee your security and privacy program, review its effectiveness, and take steps to align it with business objectives and regulatory obligations.
These requirements align closely with the ISO/IEC 27001:2022 (ISMS) and ISO 27701:2025 (PIMS) governance requirements. Particularly, Clause 5: Leadership for both standards defines top management commitment, assignment of roles and responsibilities, and maintaining up-to-date privacy and security policies.
2. Information security controls
Implementing controls to ensure the confidentiality, integrity, and availability of personal information is a critical part of ISMS-P certification. These are controls that guide information security risk management throughout the data lifecycle, such as access and vulnerability management and incident response and business continuity plans.
Document your controls and the rationale behind implementations to have defensible proof during certification audits. You must demonstrate control effectiveness in practice through vulnerability testing, maintenance, and records of ongoing monitoring.
Many of these requirements map directly to ISO 27001 control objectives, so if you already maintain a robust ISMS, you can build on your existing implementations and focus on Korea-specific documentation.
3. Personal information protection
To align with ISMS-P’s data privacy expectations, your organization must demonstrate how personal information is collected, stored, used, shared, and destroyed, and how you protect user rights. This includes supporting data subject rights recognized under Korea's PIPA, such as the rights to access, correct, and delete personal information, and request suspension of processing. This area maps closely with ISO 27701 information privacy management requirements. It also complements ISO 27001 with privacy-specific controls.
Alignment includes implementing encryption that safeguards data both at rest and in transit, alongside access controls that restrict access and processing to authorized parties.
Another point of overlap between ISMS-P and ISO 27701 is third-party oversight. If you rely on external providers to process personal information, you must verify that they maintain appropriate safeguards and handle information in line with applicable privacy and security requirements.

4. Monitoring and continuous improvement
Like ISO standards, ISMS-P is not a one-time certification exercise. You need ongoing efforts to evaluate the effectiveness of your controls, address any gaps, align with evolving requirements, and demonstrate that improvements are integrated into day-to-day operations.
Conduct regular internal audits, review security and privacy metrics, track control effectiveness over time, and investigate incidents to identify corrective actions.
Like ISO 27001 and ISO 27701, ISMS-P expects continual improvement to be built into the management system. Organizations with a mature ISO setup can build their ISMS-P program on existing governance processes instead of creating a parallel stream of compliance workflows.
Key differences between ISMS-P and ISO standards
Despite the overlaps, compliance with ISO 27001 and 27701 doesn’t mean that you’re automatically aligned with ISMS-P.
“Organizations often assume their ISO compliance will automatically satisfy ISMS-P. In practice, the management system translates well, but the Korean regulatory requirements introduce additional obligations that ISO doesn't cover. That's why ISO 27001 should be viewed as the starting point for ISMS-P, not the end goal.”
Evan Rowse
The primary difference is the regulatory weight: ISMS-P is a certification tied directly to the South Korean regulatory environment, while ISO 27001 and ISO 27701 are voluntary international standards.
Privacy is another gap that catches teams off guard. Because ISO 27701 has “privacy” in its name, organizations often assume it covers the personal information aspect of ISMS-P. While they do overlap at the control level, ISO 27701 is designed to stay jurisdiction-neutral and map to regulations like the GDPR, so it deliberately stops short of any one country’s legal specifics.
ISMS-P inherits those specifics directly from Korea’s Personal Information Protection Act, so even ISO-certified teams may face genuinely new work at the legal implementation layer. The category may be shared but the statutory detail underneath isn’t.
Other key differences include:
- ISMS-P is a certification tied directly to compliance with South Korea’s regulatory framework, with KISA overseeing the certification program on behalf of MSIT and PIPC. ISO certifications are issued by accredited certification bodies under internationally recognized standards.
- The audit process differs, with ISMS-P assessments focusing on demonstrating compliance with South Korean privacy and security requirements alongside the implementation of technical and organizational controls.
- ISMS-P has additional localization requirements that reflect South Korean expectations.
Why ISO 27001 and 27701 can accelerate ISMS-P readiness
ISO 27001 and ISO 27701 certifications bring many advantages when pursuing ISMS-P, notably time and effort savings from using existing control evidence and governance structures. You can adapt existing risk management, security, privacy, documentation, and audit practices for ISMS-P, while your teams only need to focus on the Korea-specific requirements that ISO standards don’t cover.
This relationship also works in the other direction. Korean companies can rely on their established ISMS-P implementations to expand compliance to ISO 27001 and 27701.
You can accelerate readiness further by using leading GRC solutions like Vanta to streamline operational effort and bring ongoing monitoring in one place. Vanta can help you map control evidence across multiple frameworks as well as automate evidence and monitoring activities to minimize compliance busywork.
How to build a unified compliance program for ISO and ISMS-P
To build a unified program that identifies shared requirements and centralizes compliance activities, follow these best practices:
- Establish a common controls framework: Build a shared control structure that meets criteria for both the ISO standards and ISMS-P. This makes it easier to identify reusable controls and gaps that require additional work.
- Centralize evidence management and oversight: Maintain a single source of truth for policies, procedures, and control documentation so teams can prepare for audits efficiently.
- Align security, privacy, and engineering teams: Coordinate with different teams to unify compliance efforts, assign responsibilities, and maintain consistent practices across ISO and ISMS-P programs.
- Leverage automation: Automate evidence collection and ongoing monitoring to reduce the risk of gaps between certification cycles and support scaling compliance programs.
The best compliance automation solutions focus on giving your team a structure for repeatable compliance activities and control maintenance.
