68% of UK Firms Plan to Increase Cyber Spending as AI Risks Rise
The Barclays Business Prosperity Index reveals a sharp pivot in enterprise security strategy as AI-driven threats outpace legacy defences.

British businesses are opening their wallets on cybersecurity at a rate not seen in years — and artificial intelligence is the reason why. According to the Q1 2026 Barclays Business Prosperity Index, 68% of UK firms plan to increase their cybersecurity budgets over the coming twelve months, a figure that tracks directly with the accelerating adoption of AI tools across enterprise operations. The message is unambiguous: the same technology powering productivity gains is simultaneously expanding the attack surface in ways that traditional security architectures were never designed to handle.
AI as Both Asset and Liability
The paradox at the heart of this spending surge is that AI is simultaneously the solution and the problem. Enterprises across finance, retail, logistics and professional services have aggressively deployed large language models, automated decision systems and generative AI tooling throughout their workflows. Each new integration creates fresh vectors — prompt injection attacks, model poisoning, data exfiltration through AI interfaces, and adversarial inputs that can manipulate automated processes in ways human operators never anticipate. Threat actors have been equally quick to weaponise AI, using it to craft hyper-personalised phishing campaigns, generate convincing deepfake credentials and automate vulnerability scanning at scale. The asymmetry between attacker capability and defender readiness is precisely what is forcing budget conversations to the top of the boardroom agenda.
Budget Intent vs. Strategic Clarity
Willingness to spend, however, does not automatically translate into effective defence. Security analysts at firms including Gartner and Forrester have repeatedly flagged a persistent gap between cybersecurity investment intentions and the strategic coherence of how those funds are actually allocated. A meaningful share of increased budgets tends to flow toward reactive tooling — endpoint detection, incident response retainers and compliance-driven controls — rather than into proactive AI-specific security architecture, red-teaming programmes or zero-trust implementations that address the structural vulnerabilities AI adoption introduces. For UK firms operating under the growing weight of the Network and Information Systems (NIS2) transposition obligations and the ICO's increasingly assertive enforcement posture, misallocated spend carries both technical and regulatory consequences.
"68% of UK firms plan to increase cybersecurity budgets in the next year — the Barclays Business Prosperity Index Q1 2026 marks one of the strongest signals of enterprise security urgency recorded in recent cycles."
What the Money Needs to Buy
Security leaders pressed on spending priorities are increasingly pointing toward three areas: AI-aware threat detection platforms capable of identifying anomalous model behaviour and data pipeline manipulation; identity and access management overhauls that account for non-human identities introduced by AI agents and automated workflows; and security awareness training that reflects the new social engineering landscape shaped by generative AI. Supply chain security is also climbing the list, as firms recognise that third-party AI vendors and API integrations represent a significant and underscrutinised exposure. The firms that simply pour additional funding into legacy SIEM deployments or bolted-on AI marketing claims from incumbent vendors risk a false sense of improved posture while the actual threat landscape shifts beneath them.
The 68% figure is a strong signal that UK business leadership has moved past debating whether AI security is a real concern. The harder question — and the one that will define which organisations emerge from this period with genuine resilience — is whether that financial commitment is being matched with the architectural thinking and specialist talent required to spend it well. As adversarial AI matures and the regulatory environment tightens, good intentions backed by poorly directed budgets will not be enough. The investment window is open; the strategic clarity still needs work.
Editorial Note
Infosecurity Magazine is a reputable cybersecurity publication with established credibility. The 68% figure aligns with trends shown in multiple 2023-2024 industry reports (Gartner, Forrester, CiscoSecurityOutcomeStudy) indicating increased cybersecurity budgets. However, the specific statistic should be traced to its original source (likely a UK-specific survey) to verify methodology and sample size.
