Five Cybersecurity Predictions for 2026: Identity, AI, and the Collapse of Perimeter Thinking

SecurityWeek argues that by 2026 identity will fully replace the network as the primary attack surface, with breaches centred on logging in rather than breaking through firewalls and attackers exploiting identity workflows, help desks, and recovery processes.

It predicts that AI will become the attacker’s force multiplier and the defender’s necessity, with generative AI enabling highly personalised phishing, deepfake-enabled social engineering, and real-time voice impersonation attacks, prompting defensive AI deployed at machine speed. The piece also warns that deepfakes will drive a crisis of trust in digital interactions, making video and voice poor proofs of identity and forcing redesigned workflows around cryptographic trust and continuous verification.

It notes that compliance-driven security will be exposed as inadequate, as many organisations fail to stop identity-based attacks despite checking the boxes on frameworks. Finally, it suggests security teams will be measured by business enablement rather than tool count, driving consolidation around platforms that span identity, endpoints, and user behaviour while reducing tool sprawl.

According to Business Insider, a tech journalist recently cloned her own voice with an inexpensive AI tool to fool a bank’s IVR and live agent, illustrating the immediacy of these risks.
