At GS InfoSec Auditing (GSIA), we provide independent, high-quality Auditing Services for Information Security Management Systems (ISMS) on behalf of accredited Certifying Bodies.

Our auditors combine deep subject matter expertise in standards like ISO 27001 and TISAX® with decades of experience across industry, manufacturing, and the public sector. We understand both the practical realities of how organizations operate and the rigorous expectations of Certifying Bodies. That means we deliver audits that are not only technically sound, but meaningful and credible.

As a dedicated audit partner – not an implementation firm – we uphold the independence and integrity essential to the certification process. Our focus is exclusively on auditing, and we take that responsibility seriously.

We partner with Certifying Bodies to extend their reach, maintain audit quality, and ensure each engagement reflects the professionalism and objectivity expected by Clients and Accreditation Bodies alike.

If you’re looking for a trusted extension of your audit team – seasoned, impartial, and aligned with ISMS standards – GSIA is ready to support your audit program.
