In 2024, 47% of organisations surveyed said they fell victim to at least one significant cyber attack. This figure shows the extent to which cyber security is becoming an essential strategic issue for organisations. Faced with increasingly complex and diversified threats, governments need to straighten their regulations and businesses must adopt appropriate strategies to protect their systems and sensitive data. 

An ever-changing cyber threat landscape

Cyber attacks are increasing and are now exploiting advanced technologies to bypass traditional defence systems. According to the ANSSI's latest Panorama de la cybermenace report, several major trends are emerging: 

• Digital espionage: Strategic industries and organisations close to the government are particularly targeted by state-sponsored or private actors seeking to steal sensitive data.
• Destabilisation operations: These attacks, often motivated by geopolitical conflicts, include DDoS attacks, website defacement and sabotage.
• Ransomware: As destructive as ever, they are facilitated by readily available generators and source code, enabling even novice cyber criminals to use them.
• Targeting mobile devices: Executives are particularly targeted by attacks on mobile devices aimed at stealing sensitive data.

• Emerging threats: Deepfakes, capable of impersonating an individual with disturbing accuracy and attacks targeting IoT devices are expanding the attack surface.

  This rapid evolution in cyber threats underlines the importance of strengthening legal frameworks to provide organisations with appropriate regulatory protection.

  
  A stronger regulatory framework

  
  In response to these growing challenges, new regulations have been introduced to strengthen cyber security:

• The NIS2 Directive: Imposes strict cyber security measures on important and essential entities.
• The Critical Entity Resilience (CER) Directive: Aims to strengthen the resilience of critical infrastructures against physical and digital threats.
• The “SREN” (Security and Regulation of the Digital Space) law: Promotes digital sovereignty by limiting dependence on non-European suppliers.

• The DORA (Digital Operational Resilience Act) regulation: Specifically designed for the financial industry, it strengthens operational resilience against technological risks.

  The regulatory context helps establishing a framework to support businesses in adopting robust strategies to secure their systems and anticipate new threats.

  
  Advanced strategies to counter attacks  

  To meet the challenges of 2025, organisations must combine technological innovation with advanced cybersecurity practices:

• Reinforcing the protection of mobile devices: Business mobile devices need to be secured with solutions that ensure end-to-end encryption.
• Adopting a Zero Trust architecture: This method is based on systematic verification of each connection to limit unauthorised access.
• Securing IoT devices: Present in critical industries such as healthcare and energy, they represent a vulnerable point of entry that must be protected.
• Anticipating the quantum threat: Although this threat is still emerging, it is crucial to start considering the adoption of post-quantum cryptographic solutions.
• Employee training and awareness: They are often the main targets of cyber threats. Regular training helps to reduce this risk.These strategies are not limited to reacting to current threats, but also aim to anticipate emerging ones. The year 2025 promises to be a decisive milestone in the field of cyber security. While threats continue to multiply and become more complex, they are also forcing organisations to innovate and collaborate more. While essential, regulatory frameworks will need to be supported by proactive adoption of technologies and collective mobilisation. To overcome these challenges, the objective is not limited to defence, but extends to building a resilient and trustworthy digital ecosystem. More than ever, cyber security needs to be seen as a strategic lever for the future.
