Cybersecurity And Risk Predictions For 2026: Key Trends To Watch

Cybersecurity Predictions for 2026: Navigating the Evolving Threat Landscape

The year 2025 was marked by significant challenges for cybersecurity professionals, with a change in political leadership in the US introducing instability within federal cybersecurity agencies and having a ripple effect worldwide. The shift in focus from generative AI to agent and agentic AI for productivity, cybersecurity, and malicious activities also posed new threats. Furthermore, the increasing variety of cyberattacks targeting critical infrastructure and average businesses kept security and risk teams on high alert. As we move into 2026, it’s essential to understand the key trends that will shape the cybersecurity landscape.

The continued political instability, coupled with the advancements in technology being used by cybercriminals, will force security, risk, and privacy leaders to adapt their defensive technologies and prepare their workforce for these shifts. To help business and security leaders focus their attention in the year ahead, we’ve identified three critical cybersecurity and risk predictions for 2026. These predictions are based on the current trends and the evolving threat landscape, and they highlight the need for proactive measures to mitigate potential risks.

Agentic AI Deployment and Public Breaches

The deployment of agentic AI is expected to cause a public breach, leading to employee dismissals. Since the launch of generative AI in 2022, there have been several data breaches or incidents affecting the integrity or availability of sensitive data. As companies begin building agentic AI workflows, these issues will become more prevalent. It’s crucial for security organizations to enable businesses to develop agentic applications with minimum viable security, following the AEGIS framework, and implementing data security controls to track data provenance.

This prediction emphasizes the need for security leaders to prioritize the development of agentic AI applications with robust security measures in place. By doing so, they can minimize the risk of public breaches and ensure the integrity of sensitive data. The AEGIS framework provides a comprehensive approach to securing intent, ensuring appropriate identity and access management controls, and implementing data security controls.

Government Nationalization of Critical Telecom Infrastructure

Five governments are expected to nationalize or place restrictions on critical telecom infrastructure in 2026. The Salt Typhoon cyberespionage campaign, attributed to nation-state actors, breached over 600 organizations across 80 countries, exposing the vulnerability of commercial telecom. In response, governments have started to take measures to assert control over telecom security. For instance, Australia has reinforced the Security of Critical Infrastructure Act reforms, while Italy has advanced a €22 billion restructuring of Telecom Italia’s network.

This prediction highlights the growing concern among governments about the security of critical telecom infrastructure. As the threat landscape evolves, governments will likely take unprecedented control over telecom security, and CISOs must strengthen continuous monitoring of critical ecosystem risks. By evolving to continuous control monitoring, security leaders can stay ahead of new security regulations and ensure the integrity of telecom infrastructure.

Quantum Security Spending on the Rise

Quantum security spending is expected to exceed 5% of the overall IT security budget in 2026. Forrester estimates that commercial quantum computers will break today’s asymmetric cryptography in less than 10 years, and security teams will need to ramp up quantum security spending overnight. This will involve retaining consulting services to plan quantum security migrations, replacing outdated cryptographic libraries and components, and investing in cryptographic discovery and inventory tools.

This prediction emphasizes the need for security leaders to prioritize quantum security spending and develop a comprehensive strategy for quantum security migrations. By doing so, they can ensure the integrity of sensitive data and stay ahead of the evolving threat landscape. Quantum security is no longer just a concern for banking and critical infrastructure; all CISOs must consider similar spending to mitigate potential risks.
