Continuing its global expansion plan Integrity360 has acquired pioneer cyber security specialist Holiseum headquartered in Paris, France. The terms of the transaction were not disclosed.  The acquisition will enable Integrity360 to accelerate its growth in France and continental Europe and significantly provide a new and exciting services practice focused on Operational Technology (“OT”) and Internet of Things (“IoT”) technologies which complement Integrity360’s existing service practices.  Partnering for cybersecurity Those include cyber risk and assurance, cyber security testing, incident response, infrastructure, Microsoft cyber, payments compliance, and a highly comprehensive range of cyber security managed services including managed detection and response (“MDR”) solutions.  Holiseum will continue to operate from its existing three facilities in France but with the benefit of the full resources and capability of the wider Integrity360 business.  Protecting industrial systems Holiseum is a consultancy specialises in industrial infrastructureHoliseum, founded in 2018, is a highly respected and well-established cybersecurity consultancy that specialises in critical and industrial infrastructure. It serves approximately 80 customers throughout France and selected international locations from facilities in Paris and Nimes including organisations operating in the energy, infrastructure, manufacturing, transport and financial sectors.  Trusted in OT protection In particular Holiseum is an expert in OT technology and has helped many global corporate and infrastructure organisations secure and evolve their OT environment and associated IT estates.   Holiseum’s reputation is underpinned by several security accreditations from ANSSI – the National Cybersecurity Agency of France – including PASSI (cybersecurity audit services) and PACS (cybersecurity support and consulting) – where Holiseum is one of the first three certified organisations in France.  Securing critical infrastructure Holiseum’s portfolio of services include audit, training, investigation and a full suite of OT consulting solutions. Securing critical infrastructures is a high priority for many governments and corporate organisations across the globe due to the alarming rise in attacks on industrial and energy infrastructure. Pioneer industry analyst Gartner has commented that such attacks could result in the weaponisation of OT environments to seriously harm human life.  Despite the tightening of the regulatory environment with the introduction of cyber security frameworks including NIS2 (Network and Information Security 2) and DORA (Digital Operational Resilience Act) the challenge of continuously securing critical infrastructure remains acute.  Holiseum will form a major new practice within Integrity360 dedicated to the mission of aiding, protecting and supporting both government and industrial infrastructure. The existing Holiseum team of 32, will be rapidly expanded in France and across all other Integrity360 markets in support of this mission.  Strengthening cybersecurity Integrity360’s innovative range of services have been recognised on multiple occasions by GartnerIn addition, Holiseum’s headquarters in Paris will form a new regional hub for the group from which it will deliver the full suite of Integrity360 services, and during 2025 an additional Paris based SOC (Security Operations Centre) will be launched to join the existing network of six SOC’s across EMEA (Dublin, Stockholm, Naples, Sofia, Madrid and Cape Town). The SOC teams deliver a wide ranging set of managed services for customers including EDR, XDR and MDR (Endpoint Detection and Response, Extended Detection and Response, and Managed Detection and Response).  Integrity360’s innovative range of services have been recognised on multiple occasions by Gartner, namely as a Representative Vendor in the Gartner market guide for Managed Detection and Response services.  Driving innovation in security The addition of Holiseum brings group revenues to over €160m and a dedicated cybersecurity team of over 700 employees. Further innovation and demand for its services across the EMEA region will expand group revenues in 2025 across all territories. Ian Brown, Executive Chairman at Integrity360 commented “We are very excited to be welcoming the team from Holiseum to Integrity360.
