The ISO/IEC 27001 standard is the global benchmark for managing information security, and its 2022 update reflects the evolving cybersecurity landscape and industry best practices. Organisations currently certified under ISO 27001:2013 face a critical deadline: they must migrate to the ISO 27001:2022 version before October 31, 2025, to maintain certification validity.

This update is more than just a simple version number change; it introduces significant revisions that enhance security controls and improve integration with other management systems.

If navigating this transition feels overwhelming, this guide breaks down everything an organisation needs to know, including the key differences, transition requirements, a suggested roadmap, timeline, costs involved, and how to choose the right partners for a smooth upgrade.

What’s New in ISO 27001:2022 Compared to the 2013 Version?

ISO 27001:2022 builds on the foundation of the 2013 standard but introduces major improvements to address modern threats and simplify compliance. The most noticeable change is the restructuring of Annex A controls. The previous 114 controls have been consolidated into 93, reorganised under four broad categories: organisational, people, physical, and technological controls. This streamlining reduces overlap and makes implementation more straightforward.

Additionally, 11 new controls have been introduced, targeting critical areas such as threat intelligence, secure software development, cloud security, and data masking. These changes reflect the pressing needs of today’s threat environment. Importantly, the standard’s language and structure were updated to align more closely with ISO’s High-Level Structure (HLS), facilitating easier integration with other standards like ISO 9001 and ISO 22301.

While the core principles, such as risk management and continual improvement, remain intact, these refinements position ISO 27001:2022 as a more relevant and robust framework for managing information security today.

Transition Requirements: What Organisations Must Do

Organisations certified under the 2013 version must perform a structured transition to comply with the updated controls and clauses. First, a thorough gap analysis is essential to identify where existing controls and documentation fall short against the 2022 requirements. Because of the new and reorganised controls, your organisation’s Statement of Applicability (SoA), risk assessment, and risk treatment plans will need review and revision.

Updating your Information Security Management System (ISMS) documentation, including policies, procedures, and records, to reflect these changes is critical. Equally important is ensuring that personnel are trained and aware of new controls and processes. The transition also requires conducting an internal audit aligned with the new standard before the external transition audit can be scheduled.

Remember, the transition audit can be integrated within your surveillance or recertification audit if timed well, or conducted as a standalone audit. Communicating and collaborating closely with your certification body early in the process greatly eases the transition.

A Practical Roadmap to Transition

Successfully upgrading your ISO 27001 certification involves several key steps. Begin by deeply understanding the new requirements and controls, using official ISO documents and transition toolkits offered by reputable certification bodies. Conduct a comprehensive gap assessment that maps your current controls against the 2022 framework to identify what needs to be implemented or updated.

Next, update your risk assessment to account for new threats and technologies emphasised in the latest standard. This revision ensures your SoA aligns with the current control set. Revise ISMS documentation accordingly, reflecting updated controls and processes. Staff awareness and training programs should be followed to guarantee everyone understands their roles in maintaining compliance.

Before scheduling the external audit, perform an internal audit under the new standard’s requirements to verify that gaps are closed and the ISMS functions properly. Plan this sequence well, as the transition audit must be completed so certification decisions occur before the October 31, 2025, deadline.

Understanding the Transition Timeline and Deadlines

The updated standard was released in October 2022, initiating a three-year transition period. Organisations must complete their upgrade audits by October 31, 2025. While technically organisations have until this date, delaying action increases risk, especially for small and medium enterprises that may face scheduling bottlenecks with auditors closer to the deadline.

Many certification bodies recommend scheduling transition audits well in advance, ideally by mid-2025, to allow for handling any unforeseen corrective actions. Additionally, from May 1, 2024, any newly issued ISO 27001 certificates must be under the 2022 version, meaning first-time certifications will no longer be granted against the 2013 standard.

What Does It Cost to Migrate to ISO 27001:2022?

The financial impact of migration varies widely, depending on organisation size, current ISMS maturity, and resource availability. Costs mainly stem from internal efforts like staff training, documentation updates, and implementation of new controls. External expenses include fees for consultants who assist with gap assessments, training, and audits, plus certification bodies’ charges for conducting the transition audit.

Typically, the transition cost is less than that of an initial ISO 27001 certification, but it should still be budgeted carefully. Early planning helps avoid expensive last-minute fixes and enables spreading costs over time.

What Happens If the October 31 2025 Deadline Is Missed and How to Recover Fast

If the October 31, 2025, deadline for transitioning from ISO 27001:2013 to ISO 27001:2022 is missed, organisations lose their current ISO 27001 certification. This means they no longer hold a valid, recognised information security management certification, which can have serious business impacts such as losing the trust of clients, missing out on contracts that require up-to-date certification, and potentially facing regulatory non-compliance penalties. The transition is mandatory, and thus, the 2013 certification expires with no exceptions after the deadline.

Losing certification means organisations must start the certification process afresh under ISO 27001:2022. This involves a full initial certification audit rather than a simpler transition audit, which is more time-consuming and costly. The organisation will need to fully update its ISMS systems, controls, and documentation aligned with the 2022 standard, retrain staff, and demonstrate compliance anew. This delay can cause significant disruption, loss of business opportunities, and additional costs.

To recover quickly after missing the deadline, organisations must immediately engage with expert consultants like CyberSapiens. CyberSapiens helps by conducting rapid gap analyses, prioritising control updates, revising risk assessments, and accelerating documentation u.pdates tailored to ISO 27001:2022 requirements. Their training programs speed staff readiness, while their guided internal audits ensure preparedness before scheduling the full certification audit.

With CyberSapiens’ structured approach and experience, organisations can minimise downtime without certification, accelerate compliance, and regain certification status faster, helping restore customer confidence and business continuity as soon as possible after the missed deadline
