How to Maintain ISO Certification?

After completing the long certification process, it’s vital businesses plan to maintain compliance over the long run. To do so, there’s a variety of practices companies implement to ensure they remain compliant.

1. Utilizing ISMS As a core component, it’s important businesses prioritize and utilize their information security management (ISMS). Practically speaking, a business must implement all procedures, protocols, and controls as required by ISO 27001 clauses.

2. Updated Documentation Another core component businesses should plan for; updating their documentation to remain compliant. As business operations evolve and expand, companies should maintain their policies and procedures to reflect these changes.

Continued maintenance offers benefits when it comes time for renewal. In addition to this, businesses will benefit from having a more regular review of their policies and procedures to ensure they’re properly optimized.

3. Continued Testing and Risk Review With the digital world constantly changing, businesses must ensure they continually test and review their risks.

As new threats emerge, risk management strategies should be updated to reflect this change. The process of continuous testing helps ensure that these risks are properly identified and then mitigated, reconciled, or taken as an accepted risk.

4. Effective Internal Audits and Management Review Similar to the above point, businesses should continue their efforts to audit their systems regularly.

During these more regular testing efforts, team leaders should properly understand their system to ensure updates lead to a productive result. This will also allow leadership to be stay updated on any changes to the ISMS and actively drive changes when necessary.

5. Implement Proper Remediation Policies After discovering corrective actions, it’s important to process the necessary changes that led to a solution. Not only will this allow operations to be improved with regards to security, but it also helps with the compliance certification process. With these two important benefits known, it should be apparent to leaders the importantance of ISO 27001 certification and a proper remediation policy.

How Long is ISO 27001 Valid for Once Certified?

ISO 27001 certification is valid for 3 years.

However, organizations need to manage and maintain the ISMS throughout the entire period. The certified body performs audits every year and may strip an organization of its certification if it does not meet the requirements.

An ISO certification renewal is necessary after 3 years. For ISO 27001 certified companies to keep the certification, they must renew the certification. Otherwise, it becomes invalid.

Certification Renewal

As businesses approach their certification renewal date, they should proactively prepare for the renewal. The last thing businesses want is to have to do the entire process again.

Thankfully, the renewal process is not as intensive as the initial certification. With this in mind, businesses should plan around 3 months prior to their certification expiration date to ensure they’re properly prepared.

Owners will need to review their compliance controls to ensure they fill any gaps leading to nonconformity with the standards. Furthermore, the renewal process does require an auditor in a similar capacity to become certified.

After the auditor completes the audit, businesses will be notified with a pass or fail summary. For businesses who fail the renewal process, they have 15 days after the report to reconcile any corrective actions.
