Cybersecurity trends for 2025, as predicted by TCS, Fortinet, and ESDS, include increased exploitation of generative AI (genAI) in cyberattacks, a greater emphasis on cloud security, and the development of stronger cyber resilience strategies.

Predictions for 2025:

• GenAI: A Double-Edged Sword: While genAI will likely fuel more sophisticated cyberattacks (e.g., deepfakes, phishing), it will also empower enterprises to develop advanced threat detection and response systems.
• Cloud Security Takes Center Stage: With growing cloud adoption, robust security protocols (encryption, access controls, continuous monitoring) will be critical. Fortinet anticipates a rise in cloud-specific vulnerabilities exploited by attackers.

  “Given that most organisations rely on multiple cloud providers, it’s not surprising that we are observing more cloud-specific vulnerabilities being leveraged by attackers, anticipating that this trend will grow in the future,” Fortinet noted.

• ‘Secure by Design’ Goes Mainstream: Integrating cybersecurity into product and service design will become essential, particularly with the rise of IoT, EVs, and connected infrastructure. TCS emphasizes the need for stronger device hardening and secure communication channels for IoT devices.
• Cyber Resilience Back to Basics: Focus will shift to fundamental cyber resilience practices like regular backups, incident response plans, and business continuity measures.

• Attack Chain Specialization: Fortinet predicts that Cybercrime-as-a-Service (CaaS) providers will specialize in specific segments of the attack chain.

• Flexible Supply Chains for Operational Integrity: TCS highlights the need for adaptable supply chains to navigate geopolitical changes and protect sensitive data, ensuring operational integrity.

• Automation-First Cybersecurity: TCS advocates for an “automation-first” approach integrating various security components (SIEM, SOC, SOAR, XDR) to combat threats from GenAI, quantum computing, and 5G. Industry-specific, integrated cyber-physical security solutions are expected to gain traction.

Industry experts emphasize the evolving threat landscape and the need for proactive cybersecurity measures. Organisations must adopt a comprehensive approach encompassing zero-trust, EDR, continuous threat intelligence monitoring, and integrated IT/OT security systems.
