Why this matters now
In early 2026, many startups and European SMEs are discovering a difficult operational reality during customer due diligence, procurement renewals or investor reviews: their ISO 27001:2013 certification is no longer valid, and the transition to ISO 27001:2022 was not completed before the 31 October 2025 deadline.
For fintech companies and fast-growing technology businesses, this issue is rarely discovered during a scheduled internal review. It usually appears in operational situations that create immediate pressure. A sales team preparing a contract with a banking customer receives a compliance questionnaire asking for the updated ISO 27001:2022 certificate. A procurement department requests evidence aligned with the revised Annex A controls. An investor conducting technical due diligence notices that the organisation still references the 2013 version in its security documentation.
At that point, the problem is no longer theoretical. The organisation must quickly determine whether its information security management system can be recovered without restarting the certification journey from zero.
Industry context
The transition from ISO 27001:2013 to ISO 27001:2022 officially ended on 31 October 2025. After that date, certificates based on the previous standard were withdrawn or expired. Many organisations underestimated the operational effort required for the transition because the update initially appeared incremental rather than structural.
In practice, startups and SMEs often postponed the project while prioritising product delivery, fundraising, cloud migrations or regulatory initiatives linked to NIS2, DORA or customer onboarding requirements. Security teams frequently assumed that the transition would consist mainly of documentation updates. During implementation, they discovered that auditors expected evidence showing that revised controls had been operationalised across real business processes.
This became particularly visible in fintech environments where third-party risk management, cloud governance and access control reviews already consume significant internal resources. According to several certification bodies and advisory firms operating in Europe during 2025, a recurring issue was not the absence of security controls themselves, but the lack of updated Statements of Applicability, incomplete risk treatment mapping and inconsistent evidence collection.
A common operational scenario illustrates the problem clearly. A SaaS startup may already use MFA, endpoint detection, vulnerability management and cloud logging across its infrastructure. However, during the transition review, the auditor requests evidence mapped against the new ISO 27001:2022 Annex A structure. Internal teams then realise that their documentation still references legacy control numbering, outdated suppliers and retired infrastructure components. The technical controls exist, but the governance layer no longer reflects operational reality.
Practical approach
Organisations that missed the transition deadline generally face two separate concerns. The first is reputational and commercial: how to explain the certification status to customers, partners and auditors. The second is operational: how to rebuild compliance readiness quickly without generating unnecessary disruption.
The most effective recovery projects in 2026 are following a focused four-stage approach rather than attempting a complete redesign of the ISMS.
The first step is a targeted gap assessment against ISO 27001:2022 requirements and Annex A controls. This should not become a three-month consulting exercise. The objective is to identify where the existing ISMS no longer matches current operational practices. In many startups, the largest gaps appear in asset inventories, supplier governance, secure development evidence and incident response documentation.
The second step involves refreshing the Statement of Applicability. For many organisations, the SoA becomes the central recovery document because it demonstrates whether the company actually understands how its controls operate today. Teams often discover during this phase that certain controls were marked as implemented years ago without clear ownership or measurable evidence.
A practical decision point usually emerges here. Some organisations attempt to preserve every historical control statement to minimise audit findings. Others decide to simplify the control environment and rebuild the SoA around operationally verifiable controls. In most recovery projects, the second approach produces better results because auditors can more easily validate controls that are actively maintained by engineering, IT and security teams.
The third step is what many security leaders informally call the “evidence sprint.” This phase focuses on producing verifiable operational records for the controls already described in the SoA. Evidence typically includes access reviews, onboarding workflows, cloud security monitoring records, vulnerability remediation tickets, supplier assessments and security awareness tracking.
The final stage is defining the audit strategy itself. Organisations need to determine whether they are pursuing a transition recovery with the previous certification body or effectively restarting certification under ISO 27001:2022. The answer often depends on how much time elapsed after the withdrawal date and whether surveillance cycles were already interrupted.
Operational implementation
Recovery projects succeed when ownership is distributed across operational teams instead of remaining isolated within compliance functions.
In fintech companies, security leaders frequently coordinate weekly implementation checkpoints involving engineering, HR, IT operations and legal teams. These sessions are rarely focused on policy writing alone. Most discussions revolve around evidence availability, missing process records and inconsistent operational practices between departments.
One professional observation appears consistently during these engagements. Security teams often discover that evidence collection becomes easier once they stop treating ISO 27001 as a documentation exercise and start mapping controls directly to daily workflows. For example, GitHub pull request approvals may support secure development evidence, while identity provider logs can demonstrate access review processes without requiring additional manual reporting.
This operational mapping is particularly important for startups where teams are small and documentation maturity varies significantly. A company with thirty employees may already operate securely from a technical perspective but still struggle to demonstrate governance consistency during an external audit.
Another recurring implementation issue concerns supplier management. Under ISO 27001:2022, organisations are expected to maintain clearer visibility over cloud providers, SaaS dependencies and outsourced operational services. During recovery projects, many SMEs realise that vendor reviews exist informally inside procurement or engineering conversations but were never centralised into a structured risk management process.
European regulatory developments are also influencing implementation priorities. Organisations already preparing for NIS2 or DORA compliance increasingly align their ISO 27001 recovery work with broader governance requirements, especially around incident reporting, third-party oversight and executive accountability. As a result, some companies now use the ISO transition project to consolidate overlapping compliance initiatives rather than treating each framework separately.
Metrics and visibility
One of the fastest ways to stabilise a delayed ISO 27001 transition is to create visibility around measurable operational indicators instead of relying exclusively on audit preparation milestones.
Security and compliance teams typically monitor four areas during recovery efforts.
The first is SoA completion status. This includes control ownership validation, applicability reviews and evidence linkage. Mature teams track whether every applicable control has at least one clearly identifiable operational evidence source.
The second area concerns evidence freshness. During audits, outdated screenshots and obsolete reports create immediate credibility problems. Organisations therefore begin measuring how recently each control was validated and whether supporting evidence reflects current infrastructure and business operations.
The third area involves remediation closure rates following the gap assessment. This helps executive teams understand whether implementation blockers are technical, procedural or organisational.
The fourth area is audit readiness visibility. Several startups now maintain internal dashboards showing pending evidence requests, incomplete policies and unresolved supplier assessments ahead of certification reviews. This operational visibility reduces last-minute escalation cycles that commonly appear before external audits.
For growing fintech organisations, these metrics also support communication with customers and investors. Even if certification status temporarily lapses, companies that can demonstrate structured remediation progress often maintain stronger credibility during procurement and due diligence discussions.
The Real Challenge in 2026
Missing the ISO 27001:2022 transition deadline does not automatically mean rebuilding the entire security programme from the beginning. In most startups and SMEs, the core security controls already exist inside operational workflows, cloud environments and engineering practices. The real challenge in 2026 is reconnecting those controls to governance evidence that external auditors, customers and regulators can verify.
The organisations recovering most effectively are treating the transition as an operational alignment exercise rather than a documentation emergency. A focused gap assessment, a realistic SoA refresh, structured evidence collection and a pragmatic audit strategy can restore certification readiness without disrupting daily business operations.
For startups, fintech companies and European SMEs operating in regulated supply chains, ISO 27001:2022 remains closely tied to procurement access, customer trust and compliance credibility. Recovery therefore depends less on producing perfect documentation and more on demonstrating that security controls are actively functioning across the organisation today.
