Cybersecurity
Our four security pillars
Security at Atos – our vision, our commitment
Our vision: Security as a foundation of trust
At Atos, security is a core pillar of trust and a fundamental enabler of our digital transformation mission. Our security vision is formally articulated through a Group security policy statement, co signed by the Atos Group chief executive officer and the group chief information security officer (CISO), reflecting the highest level of executive commitment to protecting our clients, partners and our own operations.
This vision is implemented through a comprehensive Group security strategy, designed to address today’s evolving threat landscape and tomorrow’s emerging risks. The strategy is driven by key challenges such as increasing cyber threat sophistication, regulatory and sovereignty requirements, supply chain security, and the acceleration of cloud, data, and AI technologies. It aligns security objectives with Atos’s Group business strategy, ensuring that security is not only protective but also a business enabler that supports innovation and customer confidence.
Our ambition is clear: to be recognized as a trusted and secure digital services partner, delivering resilient, compliant and secure solutions across all markets we serve.
End-to-end security: From suppliers to clients
Security at Atos Group is designed end‑to‑end, covering the full lifecycle of our services and ecosystems—from our suppliers and internal operations to the solutions we deliver to our clients.
Atos operates a global information security management system (ISMS) that is ISO 27001 certified, demonstrating our adherence to internationally recognized security standards and best practices. This certification applies to key Atos activities and services and is supported by a unified set of security policies, controls and governance processes across the Group.
Our people are a critical part of this approach. Atos invests continuously in security awareness, role‑based training, and professional development, ensuring that our teams understand their security responsibilities and are equipped to manage risks effectively. Security requirements are embedded into our processes, supplier relationships, and service delivery models, providing consistent protection throughout the value chain.
Proven know how and operational security capabilities
Atos brings decades of experience in securing complex, large‑scale IT and digital environments. Our security organization is built on strong governance and operational capabilities, leveraging dedicated cybersecurity resources and expert teams across regions and service lines.
Our capabilities include:
- Security operations centers (SOC) providing continuous monitoring and threat detection.
- A global computer security incident response team (CSIRT) responsible for managing and coordinating security incidents, ensuring rapid response and effective remediation.
- Offensive security services, including penetration testing and vulnerability assessments, to proactively identify and reduce risk.
- Crisis management and cyber‑resilience exercises, helping Atos and its clients prepare for and respond to major cyber or operational incidents.
These capabilities are continuously enhanced through automation, threat intelligence, and integration with our broader digital and cloud services, enabling Atos to deliver resilient and secure solutions at scale.
Working with peers: Contributing to a stronger digital ecosystem
Atos strongly believes that cybersecurity is a collective responsibility. Beyond our internal capabilities, we actively collaborate with industry peers, institutions and trusted partners to strengthen the global security ecosystem.
We are involved in recognized initiatives and communities such as the Charter of Trust and ECSO (European Cyber Security Organisation), contributing to shared frameworks, best practices, and policy discussions. Through these collaborations, Atos helps shape security standards, promote digital trust, and address common cybersecurity challenges alongside other leading organizations.
By working with our peers, Atos reinforces its commitment not only to protecting its own clients, but also to advancing security, resilience and trust across the digital economy.
Our journey with continual improvement
Security is never “done.” In an environment where threats, technologies, and regulations continuously evolve, Atos treats security as a living framework—regularly reviewed, challenged and strengthened over time. Our policies and controls are designed to guide consistent behavior, while remaining adaptable to what changes around us.
This is why our Information security management system is built around continual improvement: we assess risk, implement proportionate controls, verify effectiveness, and take corrective actions when needed. As stated in our information security policy, Atos is “committed to continuously monitor and improve security to meet the requirements of customers and align with the actual threat landscape.” We do this through regular risk assessments, ongoing recommendations to business leaders, and continuous measurement of effectiveness—for example, by “monitoring security incidents and internal, external and/or customer audits.”
By continuously improving what we have today, we ensure our security remains effective, pragmatic, and aligned with our business and client expectations—supporting resilience and sustaining trust, not only at a point in time, but as our environment evolves.
