Cybersecurity: the essential shield of our digital world

De Shagan Network was born from the passion and experience of its founder, cybersecurity expert Ibrahim-Khalil Rahman. Under 40, he already has more than 20 years of experience in cybersecurity.

A free spirit and self-made man, Ibrahim-Khalil started his first company while preparing for the baccalaureate. Impressed by his skills, a publisher chose him to maintain Carte Vitale terminals in pharmacies.

With his diploma in hand, he pursued computer science studies at the IUT of Blagnac.

Top of his class, he was spotted by Orange, France's leading IT services company, which funded his engineering studies and hired him as a security architect. As Ibrahim-Khalil Rahman likes to recall: "Orange was a great school. I quickly found myself managing major CAC 40 clients: Airbus, BNP, Safran, and major players in large-scale retail."

Successes piled up and Ibrahim-Khalil Rahman was in high demand. In 2016, he joined NTT (Nippon Telegraph and Telephone) and discovered Japanese quality. He then worked with the biggest publishers, notably Microsoft, who showed interest in him and asked him to join their ranks. Which he did.

A few months later, Ericsson and Cisco competed for his expertise. He chose Cisco, where he stayed for six years, driven by ambitious cybersecurity projects for major international events (22nd FIFA World Cup in Qatar in 2022, Paris 2024 Olympics…); iconic venues (Groupama Stadium in Lyon, Real Madrid Football Stadium, Accor Arena…); the famous game League of Legends; and restoring the information system of Assistance publique - Hôpitaux de Paris (AP-HP) following the cyberattacks it suffered during the Covid health crisis…

In 2022, with an already rich background, he created De Shagan Network, of which Cisco would be the first client. The philosophy of De Shagan Network? To make cybersecurity accessible to all, because cybersecurity is not a luxury, but an absolute necessity.

Since then, De Shagan Network has been working in partnership with the biggest names: Microsoft, Palo Alto, Fortinet, CrowdStrike, Amazon, Google, Alibaba Cloud, Cisco… Partnerships that enable De Shagan Network to offer tailored cybersecurity solutions, reliable ones, backed by AI and adapted to companies of any size.
