QCon London 2026 Security Track Host Discusses Future Cybersecurity Trends

Shifting Security Paradigms

Chris Swan, an engineer at Atsign and security track host at QCon London, reflected on discussions from QCon London 2026, outlining future cybersecurity topics. The core theme is a transition in security engineering from human-centric vigilance to automated, system-level defenses across the application stack.

Hardware-Assisted Memory Safety

One key area is hardware architectural extensions, such as CHERI, which provide a pragmatic solution for memory safety. These extensions catch out-of-bounds memory errors directly in hardware, offering an alternative to rewriting extensive legacy C/C++ codebases in languages like Rust.

Automated Governance and Supply Chain Security

The EU Cyber Resilience Act (CRA) is making Software Bills of Materials (SBOMs) a practical requirement for organizations. This regulatory push necessitates automated supply chain security and robust vulnerability exposure tracking, especially as machine-to-machine interactions increase.

The discussion also emphasized the importance of governance in securing the supply chain, adapting to rapid shifts in automated systems.

Post-Quantum Cryptography and AI Risks

With quantum computing posing a threat to traditional asymmetric algorithms like RSA and ECC, organizations must develop crypto-agility. This allows for seamless migration to NIST-standardized post-quantum algorithms.

The proliferation of autonomous AI agents introduces new risks in non-human identity management. This requires implementing fine-grained, task-based permissioning and strict least-privilege controls to mitigate potential vulnerabilities.
