Jobbeschreibung

FlashX protects small and medium-sized enterprises from identity theft – by far the most common entry point for hackers.

With FlashX, a multi-tenant SaaS Identity and Access Management (IAM) platform from Germany that is already in productive use at numerous SMEs, we prevent stolen login credentials or weak multi-factor authentication (MFA) from causing significant damage. FlashX combines password/access controls, MFA, roles, and audits in an easy-to-use interface. Hosting in the Open Telekom Cloud (Deutsche Telekom) ensures the highest data protection standards and data sovereignty. Zero knowledge and GDPR compliant by design.

Compliance guidelines such as ISO 27001, BSI IT Baseline Protection, NIS2, and KRITIS mandate the use of IAM.

Implementation in minutes – independently or with trusted IT managed service partners.
