IDECSI: strong collective protection on a reduced budget


Directors Daniel Rezlan and Daniel Benabou founded IDECSI in 2011 with the aim of creating a unique corporate data protection platform.


After a phase of research and development, IDECSI began to market its solution for protecting the inboxes of managers, executives and enterprises.
🏆 That same year, IDECSI won the prestigious Innovation Award at the Assises de la Sécurité symposium.


IDECSI developed its SaaS solution – which ranges from securing VIP mailboxes to supporting cloud environments – in order to help clients with security challenges, providing easily deployable and simple-to-use solutions.


IDECSI has been a cybersecurity pioneer developing cutting-edge technology and a disruptive approach for more than a decade.
With deep expertise in Microsoft 365, messaging systems, collaboration applications, and on-premises environments, IDECSI allows users all over the world to benefit from a real innovation: MyDataSecurity.
