The 2025 Cityforum Cyber Security and Intelligence Round Table, held in London’s Plexal innovation hub, brought together an unusually broad coalition — from the UK’s National Cyber Force to international intelligence agencies, academics, regulators, and industry. While its official theme was “the changing shape of the threat landscape,” its real value for digital forensics and incident response (DFIR) lies in the unvarnished discussion of readiness gaps, strategic blind spots, and the urgent need for cross-sector integration.

Why This Report Matters for DFIR

DFIR sits at the intersection of technology, policy, and human factors — and the report confirms all three are under strain. The sessions repeatedly stressed that cyber threats are no longer isolated incidents; they are part of sustained, multi-vector campaigns involving state actors, extremist groups, and financially motivated cybercriminals. Forensic teams are now expected to operate not only as post-incident investigators but as active participants in resilience planning and deterrence strategies.

Key Insights Through a Digital Forensics Lens

• Resilience as a Forensic Asset: Preparedness exercises and simulations are as critical for DFIR units as for first responders — they determine the speed and accuracy of evidence capture under live-attack conditions.
• Integration Gaps: Despite advances in the UK’s National Cyber Force, the report warns of fragmented management structures. For forensic analysts, this means potential delays in intelligence sharing and unclear lines of authority during investigations.
• Threat Morphology: Disinformation and cognitive operations are now intertwined with technical intrusions, requiring DFIR practitioners to expand their scope beyond pure technical artefacts to include behavioural and content-based analysis.
• Provenance & Integrity: The emphasis on data provenance aligns with the forensic need to preserve evidence chains — especially as AI-generated content complicates authenticity verification.

Gaps and Challenges Highlighted

From a DFIR perspective, several weaknesses identified in the report demand immediate attention:

• Underinvestment: Cyber resilience remains underfunded compared to traditional national security priorities, limiting the tools and training available to forensic teams.
• Trust Deficits: Persistent public-private mistrust slows critical intelligence exchanges, a major hindrance when chasing time-sensitive leads.
• Attribution Complexities: State-sponsored proxies and blended threat actors create attribution delays — a challenge that DFIR teams must overcome with faster, multi-source corroboration.
• Talent Pipeline Strain: Clearance bottlenecks and narrow recruitment channels risk leaving investigative teams understaffed when threats peak.

DFIR Takeaways

For practitioners, the report is both a warning and a roadmap. It reinforces that forensic readiness is no longer a niche discipline but a national resilience requirement. To adapt, DFIR teams should:

• Embed forensic readiness drills into national and corporate cyber exercises.
• Strengthen evidence-sharing frameworks with law enforcement and intelligence partners.
• Invest in cognitive and content forensics to address disinformation-driven attacks.
• Champion recruitment diversity and alternative vetting pathways to expand the talent pool.

Conclusion

The Cyber Security and Intelligence Report 2025 makes one thing clear: the age of reactive digital forensics is over. In its place must rise a culture of proactive investigation, cross-domain intelligence fusion, and relentless readiness. For the DFIR community, this is both a challenge and an opportunity — to position itself not only as a responder but as a strategic actor in shaping national and organisational resilience.
