- Built on Annex SL for alignment with other management systems.
- Certification valid for 3 years with annual surveillance audits.
Why Organizations Use It

Implementation Overview
Involves gap analysis, BIA, strategy development, testing, and audits. Applicable to all sizes/sectors globally. Typical process: 6-12 months, with Stage 1/2 certification audits taking 6-8 weeks. Tools automate for efficiency.
