Cybersecurity continues to be one of the top priorities for companies and individuals, especially in an increasingly sophisticated and regulated digital landscape.
With the evolution of threats and the increase in regulatory requirements (such as NIS2 and DORA), organisations need to anticipate risks and strengthen their defence strategies to protect data, systems and critical infrastructures.
Based on expert insights and reference studies, we explore the main cybersecurity trends for 2025 and how companies can prepare to face this new scenario.
- The Rise of Artificial Intelligence and Machine Learning in Cyber Defence
One of the biggest trends predicted for 2025 is the increasing use of Artificial Intelligence (AI) and Machine Learning (ML) to detect and mitigate cyber threats. AI will continue to shape the technological landscape, but it will also bring challenges. More accessible generative models could be used to create sophisticated cyberattacks, such as personalised phishing and data manipulation. To keep up with this evolution, companies will have to invest in specialised AI teams that will act as defence agents on several fronts. - Cybersecurity in the Cloud: Protecting the Digital Future
With migration to the cloud continuing to accelerate, companies of all sizes are increasingly vulnerable to the security risks associated with hosting data on cloud platforms.
The concept of Zero Trust will be one of the most widely adopted approaches. Unlike traditional security methods, which implicitly rely on internal networks, the Zero Trust model assumes that any attempted access, whether inside or outside the organisation, is suspect and needs to be checked continuously. This includes multi-factor authentication and continuous verification of users and devices. - Hacking with Artificial Intelligence
As cyber defences evolve, so do attack techniques. Sangfor warns of the evolution of ‘AI Hacking’ – increasingly sophisticated cyber attacks driven by AI. With AI being used by both defence and attack teams, cybercriminals are expected to take advantage of the technology’s capabilities to carry out smarter, harder-to-detect attacks.
These attacks could include the creation of adaptive malware and the use of AI to personalise large-scale attacks, seeking to exploit specific system vulnerabilities in real time. The growing sophistication of hackers will require companies to adopt AI-based defence technologies to identify these emerging threats before they cause significant damage. - Ransomware and Supply Chain Attacks
Growing digitalisation and greater interconnection between companies and their suppliers make supply chains increasingly attractive targets for attackers. According to Cybersafe, protection against supply chain attacks will be a security focus in 2025, as more organisations focus on protecting their external connections and supplier dependencies.
In addition, ransomware will continue to be a dominant threat, with hackers becoming increasingly bold and demanding. Companies will need to implement robust backup and recovery strategies to mitigate the impact of ransomware attacks and ensure business continuity. - The Threat of Insider Threats: Employees and Data Privacy
Internal cybersecurity will continue to be a major concern until 2025.While external threats are often the main focus, internal threats, whether due to negligence or malicious action by employees, are increasingly recognised as a significant risk.
The protection of personal data will be a priority, with regulations such as the General Data Protection Regulation (GDPR) gaining momentum.Employee awareness and training will be crucial to minimising these risks, in addition to the implementation of solutions such as DLP (Data Loss Prevention) to monitor and protect sensitive data against data loss. - The Growing Importance of Cybersecurity Education
The shortage of qualified cybersecurity professionals continues to be one of the biggest challenges facing organisations. Cybersafe mentions that, by 2025, companies will need to significantly increase their investments in training and capacity building for security teams.
Constant training will be necessary to keep up with the evolution of threats and defence technologies, and in this regard we have the help of our partner KnowBe4.
In addition, companies must adopt a more holistic approach, involving all employees, not just the IT team, in the prevention of cyber threats. Attack simulations and incident response exercises will be important tools for training teams in real situations.
Resilience: The Pillar of Cybersecurity in 2025
Cyber attacks will become more frequent and sophisticated, making cyber resilience a critical factor for business continuity.
Three fundamental pillars will guide companies on this journey:
1️- Rapid detection and response – Implementation of autonomous defence strategies to minimise damage.
2️- Strategic collaboration – CISOs, CIOs and CAIOs must work together to balance security, privacy and innovation.
3️- Regulatory compliance – Adapting to regulations such as DORA and NIS2 will be essential to avoid penalties and guarantee operational security.
‘Right of Bang”: The New Security Mindset
Digital security is no longer just about preventing attacks, but about guaranteeing quick and effective responses when they occur. This concept, known as ‘Right of Bang’, puts resilience at the heart of business strategies, enabling organisations to survive and learn from attacks.
Is your company prepared for this new paradigm? Cybersecurity in 2025 will be a game of anticipation and adaptation. Investing in technology, training and solid processes will be the key to maintaining an edge in an increasingly dynamic digital landscape.
