The internationally recognized standard for information security management systems (ISMS) confirms that Calenso protects personal data, systems and internal processes according to the highest security requirements - audited by an independent certification body.
Why ISO 27001 is so important
ISO 27001 certification is a globally recognized security standard for companies that provide digital services - especially in the SaaS and cloud sector. It creates trust among IT, compliance and business managers because it proves the structured, documented and verifiable handling of information security.
With the version ISO/IEC 27001:2022 the requirements have been tightened again - particularly in the areas of
Risk management & vulnerability analysis
Access controls & authorization management
Emergency planning & response to security incidents
Security in the supply chain & hosting
Regular internal audits & continuous improvement
