ISO 27001

ISO/IEC 27001:2017 is an internationally recognized best practice framework for an Information Security Management System (ISMS) and consists of a set of activities for managing information security risks. The ISMS is an overarching management framework that enables Clappform to effectively identify, analyze and address security risks. The ISMS also ensures that our security measures remain finely tuned to keep pace with the ever-changing security threats, vulnerabilities, and business consequences that our company faces.

GDPR Compliant

The General Data Protection Regulation (GDPR) is a legal framework that sets guidelines for the collection and processing of personal information from individuals who live in the European Union (EU).

At Clappform we are always working to keep our information processes and our security up to date. We work with a management system that not only meets the legally required GDPR standard, but also the ISO27001 standard.
