Deutsche Telekom: Hardening Security and Infrastructure
Deutsche Telekom has identified cybersecurity and digital resilience as core strategic priorities, recognising that secure connectivity is fundamental to sustainable digital transformation across its global operations.
The telecommunications giant is prioritising both digitalisation and security, understanding that protecting critical infrastructure and data is essential as organisations accelerate their digital strategies.
By integrating advanced network technologies, AI-driven optimisation and comprehensive security frameworks, Deutsche Telekom is establishing itself as a leader in secure, resilient connectivity.
Deutsche Telekom has developed a comprehensive Group Security Strategy covering six key areas: people, geopolitics, crime, regulation, technology and environment.
The strategy, aligned with ISO 27001 standards, ensures that data, systems and networks are safeguarded against threats ranging from cyberattacks to fake news and power outages.
Timotheus Höttges, CEO, Deutsche Telekom, says: "Deutsche Telekom stands for reliability when it counts most. And that means: reliable investments. In artificial intelligence and data centres. In cybersecurity and resilience."
"Across the group as a whole, we invested almost €17bn (US$19.7bn) in 2025, with €5.9bn (US$6.8) in Germany alone. Again, more than any competitor. And more than in the previous year.
"We launched more than 500 AI and data projects.”
Continuous monitoring, employee training and advanced technological controls allow the company to manage risks proactively, enabling secure, resilient digital services while supporting digital participation for millions of users.
This multi-layered approach recognises that cybersecurity extends beyond technical measures to encompass human factors, regulatory compliance and geopolitical considerations.
Protecting digital infrastructure
As digitalisation accelerates, protecting both society and infrastructure becomes increasingly critical.
Deutsche Telekom's network infrastructure is designed for resilience, with emergency power systems, mobile generators and crisis management plans in place to ensure continuity during disruptions.
The company manages climate-related physical and transition risks, such as extreme weather events, heat stress and energy price volatility, which could impact data centres and network operations.
A continuous scenario analysis ensures preparedness for potential impacts, while infrastructure hardening and redundancy measures reduce vulnerability to both cyber and physical threats.
Network infrastructure resilience is further enhanced through advanced 5G tower operations and AI-driven optimisation technologies.
These systems not only improve operational efficiency but also strengthen the security posture.
Investment in digital security
According to Deutsche Telekom, the company invested €17bn (US$19.7bn) across the Group in its 2024 financial year, with €5.9bn (US$6.8bn) in Germany alone. Timotheus emphasised this represented more than any competitor and more than in the previous year.
"We launched more than 500 AI and data projects," Timotheus added, highlighting the company's commitment to advancing technological capabilities that underpin both innovation and security.
These investments span AI, data centres, cybersecurity and resilience infrastructure.
By embedding security considerations into product design and network architecture from the outset, Deutsche Telekom aims to create inherently secure systems rather than retrofitting protection measures.
The company's approach extends across its entire value chain through supplier collaboration and enhanced transparency on security requirements. By embedding cybersecurity standards into supplier contracts, Deutsche Telekom ensures that security responsibility is shared across its ecosystem, creating lasting benefits for both the business and its customers.
This includes ensuring electronic waste is properly recycled or reused, having already achieved zero ICT waste to landfill, which reduces the risk of data breaches through improper disposal of hardware containing sensitive information.
