Excem Technologies

Excem Technologies is a Spanish technology company that develops high-technology projects in the fields of security, defence and cybersecurity. It forms part of Grupo Excem, a Spanish business conglomerate founded in 1971 by Mauricio Hatchwell Toledano. While the wider group historically operated in sectors such as commerce and cement, Excem Technologies represents its commitment to the technology and security sector. The company is led by CEO Philip Hatchwell Altaras, brother of David Hatchwell Altaras. Excem Technologies provides global technology solutions focused on physical and digital security. Its service portfolio spans advanced cybersecurity (auditing and pentesting, vulnerability detection, threat management, SOC services), defence and national security, intelligence and OSINT (communications monitoring, data analysis, open-source investigation), critical infrastructure protection, and engineering and innovation aimed at process optimisation and automation. The company states that it implements highly specialised global technology solutions and works with its own technology as well as solutions from reliable manufacturers. Its clients include public institutions and private companies. According to Catalan Wikipedia, among its clients are entities such as AENA, ADIF, Spanish ministries and other bodies linked to national security and transport infrastructure. The company regularly participates in events such as TECNOSEC, where it showcases new technologies in areas including blockchain, document verification and advanced security. In Catalonia, Excem Technologies became the awarded company for the Integrated Communications Interception and Monitoring Service (SILTEC), the communications interception system of the Mossos d'Esquadra, planned to be fully implemented between 2024 and 2028. The company has also been reported to have supplied the Reliant software, developed in Tel Aviv by former Israeli military personnel, an essential tool for Spanish Guardia Civil espionage. Various human rights organisations have pointed to Excem Technologies' participation in contracts with Spanish public administrations related to communications monitoring, including acting as a distributor of interception technology from the Israeli company Verint Systems, and reserved contracts with police forces such as the Mossos d'Esquadra and the Ertzaintza for communications interception systems such as Pegasus from NSO Group. Between 2022 and 2025 the company made donations to Likud, the party of Israeli Prime Minister Benjamin Netanyahu. Excem Technologies operates primarily in Spain with international presence. Its official website highlights experience, qualified employees, years of experience, completed projects and cities with projects as key credentials, though specific figures are not provided in the available evidence.
