CYBERSECURITY

“ By the time your security team identifies suspicious activity, the attacker has already moved deeper into your systems”

Vaibhav Dutta Vice President and Global Head of Cybersecurity Products and Services Tata Communications firewall or application layer while you wait for the development team to ship a code fix. This assumes adequate time exists between a vulnerability being announced and active exploitation.
That assumption breaks down when frontier AI can exploit newly published flaws within hours of disclosure. Protective filtering at the edge will become your primary defence mechanism, deploying security policies that block exploit attempts without equiring development cycles.
The resilience challenge Every major disruption exposes assumptions that organisations didn’ t realise they were making. Frontier AI is beginning to do the same.
If you’ re a CISO or work in a cybersecurity function, this will no doubt feel like a fundamental shift in the ground beneath your feet. Everything you’ ve built your security programme around was designed to defend against human attackers. We understand human motivation, human timelines, human constraints. Frontier AI agents don’ t have those constraints, which means the assumptions your security architecture is built on are about to become your biggest liabilities.
For UK businesses navigating an already volatile environment, the challenge is not simply managing a new cyber risk, but building the agility to withstand a world where technological change is moving faster than traditional response models were designed for.
