The growing pressure on UK CISOs is creating a looming burnout crisis.

The warning comes as a new report warned UK CISOs are under constant pressure with the result they are more likely to make errors, potentially leaving sensitive data and infrastructure exposed.

A new study by Blue Goat Cyber revealed that nearly two-thirds of UK CISOs experienced burnout over the past year, with 76% fearing a significant cyberattack is imminent. With organisations increasingly dependent on digital infrastructure, the mental health of security leaders is now a critical factor in national and corporate cyber resilience.

“Cybersecurity isn’t just a technical challenge, but also a human one. Burnout among CISOs threatens both staff wellbeing and organisational security. Long hours, 24/7 availability, talent shortages, and regulatory pressure increase the risk of mistakes and oversight. Technology alone cannot compensate for exhausted personnel,” said Blue Goat Cyber’s Cybersecurity Expert, Christian Espinosa. “Supporting UK cybersecurity teams is now imperative, as well-supported leaders increase resilience, reduce mistakes, and help protect assets. Organisations must prioritise workload management, mental health, and automation to keep personnel effective and networks secure,”

The report added while burnout exists across industries, in cybersecurity its consequences can be catastrophic:

• Split-second decisions: Exhausted leaders are more likely to misjudge alerts, leaving gaps in defences.
• Threat escalation: State-backed actors and ransomware groups exploit even small lapses.
• Compliance risk: Missteps in GDPR reporting or incident response carry huge fines.
• Talent shortages: Burned-out CISOs are walking away, leaving boards scrambling to fill critical roles.

“CISO burnout in the UK is being fuelled by complex technical demands and an unforgiving threat environment,” it added. “We are seeing a threat Surface Expansion with hybrid work, IoT, and rapid cloud adoption increasing vulnerabilities.”

UK CISOs face relentless phishing, ransomware, and DDoS activity with little downtime, while disjointed tools create excessive alerts and duplication, fuelling fatigue, the report added.

Regulatory complexity is a growing concern with GDPR, NIS2, and sector-specific compliance checks draining time and energy.

There is also a growing boardroom misalignment. “Struggles to frame technical threats as business risks are leaving CISOs isolated,” it added.

“Unchecked burnout doesn’t just harm leaders, but it also leaves entire organisations exposed. Fatigue leads to dangerous delays in system updates, and errors in firewall, IAM, and cloud setups become more likely.

“Decision fatigue undermines risk triage, letting threats slip through,” the report added. “we are facing a skills crisis. Burnout drives senior leaders out, deepening the UK’s cybersecurity talent gap.

“CISO burnout directly impacts organisational security and resilience. By investing in technical resources, smart workload management, and mental health support, companies can protect both their people and their critical systems from costly lapses.”
