It’s that time again—new year, new trends, and yes, maybe a new you if you finally tackle that inbox. But in cybersecurity, 2025 isn’t waiting for anyone to catch up. The field is set to evolve at lightning speed, fuelled by breakthroughs in technology, shifting geopolitics, and regulatory shakeups. Staying ahead means embracing change and meeting challenges head-on.

Let’s explore the top trends shaping the industry this year, with some expert insights to guide the way.


AI: A double-edged sword in cybersecurity

Artificial Intelligence continues to redefine cybersecurity, offering both opportunities and threats:

  • Weaponized AI: Attackers are using AI to exploit vulnerabilities faster and more comprehensively than ever before, particularly in IT and OT systems. Suvi Lampila, SSH Fellow, explains, “AI enables attackers to move horizontally within systems in seconds—turning a single crack into complete control almost instantly.”
  • Defensive AI: To fight back, Security Operations Centers (SOCs) are integrating AI-powered tools. These tools detect and react to threats in real time, leveraging machine learning to predict and neutralize attacks before they escalate. “Defensive AI is not just about catching up; it’s about outpacing adversaries,” adds Suvi.

Hacktivism fueled by geopolitical tensions

Hacktivism is on the rise, with geopolitical conflicts driving a surge in ideologically motivated attacks. Targeting critical infrastructure and communication networks, these threats aim to disrupt operations and spread misinformation. According to Miikka Sainio, CTO at SSH, “Organizations must prepare for politically charged attacks that blend technical sophistication with psychological impact.”

Data-centric security: Beyond the perimeter

The days of relying solely on perimeter defenses are over. Organizations are shifting focus to protect the confidentiality, integrity, and availability (CIA) of their data:

  • Encryption, access controls, and real-time monitoring are becoming standard.
  • Miikka emphasizes, “Data is the ultimate target. Protecting its full lifecycle is no longer optional; it’s essential.”

Self-sovereign identities and passkeys

The adoption of FIDO2 and passkey-based authentication is accelerating as users demand more control over their digital identities. Self-sovereign identities reduce risks associated with centralized password storage.

“Shifting to passkeys aligns with Zero Trust principles while giving individuals greater security and peace of mind,” says Suvi.

The European Cyber Resilience Act (CRA)

Effective from December 10, 2024, the CRA requires businesses in Europe to enhance their cybersecurity standards. Non-compliance could lead to significant penalties. “The CRA pushes secure-by-design from a concept to a business imperative,” notes Miikka.

Quantum-safe cryptography: preparing for tomorrow

As quantum computing progresses, post-quantum cryptography (PQC) is becoming a necessity. Long-term data confidentiality requires migrating to quantum-resistant protocols:

  • The integration of PQC with TLS and Zero Trust architectures is critical, especially in OT environments like energy and infrastructure.
  • “Preparing now ensures resilience in the quantum era,” Sainio advises.

Key market trends in OT security for 2025

Massimo Nardone, our VP of OT Security, highlights the following key trends:

  • Convergence of IT and OT security: The increasing integration of IT and OT systems demands unified security strategies to bridge traditionally siloed teams. Successful case studies, such as Stora Enso, Outokumpu, and Konecranes, demonstrate effective IT/OT convergence.
  • Zero Trust architecture: Zero Trust models are gaining traction in OT environments, emphasizing continuous authentication and authorization for users and devices.
  • Regulatory and compliance pressures: Governments and regulators are enforcing stricter OT security standards to protect critical infrastructure and assets.
  • AI and machine learning:These technologies are enhancing OT security by detecting patterns of cyber threats and anomalies in operational processes.

 

Massimo also emphasizes foundational elements critical to OT Security planning and strategy, such as incident response, endpoint protection, cloud adoption, supply chain security, awareness training, and the integration of OT security into risk management frameworks.

“Cybersecurity must be treated as a business enabler to ensure OT security investments are seen as drivers of trust, operational continuity, and competitive advantage,” says him.

Massimo highlights the need for IT and OT risk-based security measures to align with business objectives and risk profiles. Cybersecurity strategies organizations must focus on this year include:

 

  1. Advanced Privileged Access Management (PAM): Just-in-time (JIT) access and real-time validation are vital.
  2. Integrated Identity Management: Combining IAM/IGA with role-based access ensures scalability and security.
  3. Domestic innovation: European industries must invest in local cybersecurity solutions to achieve technological independence.
  4. Comprehensive monitoring: Audit trails and session recordings are critical for compliance and transparency.
