Fortinet advances quantum-safe security

The latest FortiOS capabilities help organisations with highly sensitive data deploy encryption algorithms and key distribution methods that can withstand quantum-powered attacks, stack algorithms for more robust protection, and easily transition to post-quantum security.

"At Fortinet, we’re committed to arming customers with cutting-edge technology to protect against new and emerging threats. As quantum computing advances, organisations can trust Fortinet’s technology innovation and leadership to safeguard their critical data and future-proof their infrastructures. Many enterprises are eager to take action to protect their networks from quantum-powered threats. That’s why we’ve made cutting-edge, quantum-safe features available today for FortiGate NGFW and Fortinet Secure SD-WAN customers, so they can confidently transition to post-quantum security," Michael Xie, founder, president, and chief technology officer at Fortinet said.

Quantum computers can perform complex calculations at unprecedented speeds and can easily break current encryption standards. Cybercriminals are already storing encrypted traffic to decrypt in the future, with a particular focus on industries that handle highly sensitive data that remains relevant over long periods, such as telecommunications, financial services, government, and healthcare.

With FortiOS 7.6, organisations, such as those using FortiGate next-generation firewall (NGFW) and Fortinet Secure SD-WAN, can now leverage built-in quantum-safe features designed to defend against emerging threats, including harvest-now, decrypt-later attacks. These capabilities help secure network traffic, simplify deployment, and support a smooth transition to post-quantum security. Customers have access to the following quantum-safe features at no additional cost: post-quantum cryptography methods, including National Institute of Standards and Technology-approved algorithms like ML-KEM and emerging algorithms like BIKE, HQC, and Frodo.

Quantum key distribution (QKD), leveraging quantum mechanics to enable the secure exchange of encryption keys, ensures that any eavesdropping attempts are detectable. Fortinet introduced support for QKD integrations starting with FortiOS 7.4, enabling interoperability with leading QKD vendors via standardised interfaces. This capability underscores Fortinet’s proactive approach to quantum-resilient network security by integrating quantum-safe key exchange mechanisms into its NGFW architecture.

Algorithm stacking combines multiple cryptographic algorithms to create a more resilient solution and to enhance network infrastructure security.

A hybrid mode for gradual transition to post-quantum security enables seamless integration of traditional public-key cryptography and QKD.

An enhanced user interface simplifies the configuration and management of quantum-safe settings so that network administrators can implement quantum-safe security easily.

Threat actors increasingly targeting operational technology organisations Nearly one-third (31 per cent) of operational technology (OT) organisations reported more than six intrusions in the last year, up from 11 per cent the year before, according to Fortinet's latest findings.

Fortinet's research highlights link between cyber awareness and organisational risk Fortinet released its annual Security Awareness and Training Global Research Report on October 29, highlighting the crucial role a cyber-aware workforce plays in managing and mitigating organisational risk.

Detection gaps widen as AI-fuelled attacks reshape cybersecurity in the region Fortinet, the global cybersecurity leader driving the convergence of networking and security, on June 3 announced the findings of a new IDC survey that reveals a sharp escalation in both the volume and sophistication of cyber threats across Asia-Pacific.
