A group of 116 companies and organisations has called on policymakers and industry leaders to strengthen cyber defence as capable AI systems change the speed and scale of security operations.
This article is part of the cybersecurity technology guide library.
What the group requested
The letter asks organisations to improve defensive tooling, upgrade security systems, and use an appropriate mix of lower-cost and frontier models. It also calls for coordinated public funding that would make modern defence more accessible to critical services.
Hospitals and water-treatment systems were highlighted as examples of essential infrastructure that may face serious threats without the budgets of large technology companies.
Why AI changes the equation
Agentic systems can automate reconnaissance, code analysis, and parts of an attack workflow. The same capabilities can help defenders triage alerts, find vulnerable configurations, and shorten response times.
The central policy question is whether defensive access and operational readiness can improve quickly enough to prevent the capability gap from widening.
techduopulse assessment
The letter is a call for action, not evidence that a specific programme has been funded or deployed. Its significance lies in the breadth of signatories and the focus on accessible defence for organisations with limited resources.
