There is a sense that the pace of cyber-attacks is accelerating – with adversaries compressing the time from compromise to impact from hours to minutes. As threats evolve toward machine-speed operations, traditional, human-led defence models are being pushed to their limits.
Join fellow CISOs for a private, practitioner-led discussion on how security leaders are adapting strategies, architectures, and teams to match this new tempo of risk. Explore the balance between automation and human judgment, and how other CISOs are approaching these challenges, and how MDR and managed SASE are helping to reshape real-time defence.
Key discussion points:
• Is this acceleration a measurable trend we are seeing in our own organisations and across the industry, or is it primarily vendor-driven hype?
• If attacks are getting faster, how must our defensive strategies, technologies, team structures, and security postures evolve to counter this new pace?
• What is the correct balance between mitigating this threat with technology versus addressing it through robust processes and skilled people?
• Given that a machine-speed attack can execute before a human is even alerted, should we shift our investment from prevention towards ensuring rapid response and operational resilience?
• How much faith do we really have in automated remediation? What are the business risks – such as the fear of a false positive causing an outage – that are preventing its wider adoption?
• How significantly is AI accelerating offensive capabilities, and is defensive AI keeping pace? Who currently benefits more from AI: the attacker or the defender?
• How do criminal business models like Ransomware-as-a-Service and Initial Access Brokers impact the speed and scale of threats?
• How does the pressure of combating high-speed threats impact our teams’ effectiveness and well-being? What new skills are needed when the focus shifts from manual investigation to managing automated security platforms?
• What real-time defensive capabilities are we underutilising within our existing stacks that could help us respond faster?
Held under the Chatham House Rule, this closed-door roundtable offers CISOs a trusted environment to challenge assumptions and share experiences on what it truly takes to defend at machine speed!
