TCS' 2025 Cybersecurity Outlook: Gen AI, Cloud Security, 'Zero Trust' Top Priorities

Organisations that prepare for evolving cyber threats can build the necessary resilience to operate in an increasingly complex threat landscape.

According to Tata Consultancy Services' 2025 Cybersecurity Outlook, generative artificial intelligence, cloud security and supply chain resilience will be key for organisations to effectively navigate the threat landscape in the coming year.

According to the report, the cybersecurity trends to look out for in 2025 are: 

• Rising Influence Of Gen AI In Cybersecurity: Gen AI is being exploited by cybercriminals for advanced attacks like deep fakes, phishing, data manipulation, and new malware. In response, organisations must deploy gen AI-powered threat detection and response systems. 

• Cloud Security Remains Crucial: As cloud computing adoption continues to accelerate, organisations need to implement strong security protocols like encryption, access controls, and continuous monitoring. Maintaining proper cloud configurations is crucial to prevent unauthorised access and breaches. Companies moving to multi-cloud or hybrid environments will need to adapt their security measures accordingly.

• Elastic Supply Chains For Operational Integrity: In 2025, organisations will need flexible, resilient supply chains due to changing geopolitics and partner ecosystems. Leaders must adjust their supply networks, while protecting sensitive data and maintaining regulatory compliance. 

• Secure By Design Business Models: At a time when digital technologies, IoT capabilities, and advanced connectivity are driving new business models, organisations must secure their value chains to ensure safety by design. By 2025, the growth of IoT devices will require stronger device hardening, secure communication channels and ongoing vulnerability assessments to maintain momentum in business growth.

• Zero Trust Security: Organisations are moving from traditional security models to zero-trust architecture, which requires continuous authentication and limited access to minimise threats. By 2026, most large enterprises will adopt zero-trust methods, consolidating security tools to be more efficient.

• Automation-First Approach To Managed Detection And Response: Modern MDR combines security information and event management, security operation centres, security orchestration, automation and response, extended detection and response, threat hunting, threat intelligence, and various attack simulations. These components must integrate under an "automation-first" approach for strong cyber defence against new technologies like gen AI, quantum computing, and 5G expansion. By 2025, organisations are likely to seek more industry-specific and integrated cyber-physical security solutions.

• Cyber Resilience: A robust cyber resilience strategy is crucial for organisations to handle unexpected cyber incidents. It will require taking a fresh look at the basics: regular backups, detailed incident response plans, and business continuity measures. Promoting a culture of resilience will help minimise downtime and disruptions from cyberattacks.
