Why one bad day in cyber security can define a CISO – and how Integrity360 can help

Written by Matthew Olney | 13 November 2025 07:00:00 Z

No one says it outright, but every Chief Information Security Officer (CISO) knows the truth. That success in their role is defined not by the years of stability, but by the moment of crisis. The pressure is immense, and often unfair. Cyber risk can never be reduced to zero, yet the expectation remains that it should be. 

You can spend years building the right controls, fine-tuning detection, patching exposures before they become incidents, and trying to embed awareness into every employee’s routine. You can lead from the front, communicate risk with clarity, and earn trust across every level of the organisation. You can do everything right and still lose. 

One bad day is all it takes 

Because all it takes is one breach. One bad day. One missed alert or clever deception. And suddenly, all that good work fades into the background. The headlines appear, the board demands answers, and the narrative can become brutally simple: the CISO failed. 

Boards may understand this intellectually, but in practice, a successful attack still unfortunately results in a scapegoat. Public perception demands accountability. Investors want reassurance. The easiest way to demonstrate control is to remove the person seen as responsible for losing it. 

But that dynamic is shifting. New legislation and regulatory frameworks are making it clear: the board is accountable too. 

In the UK, the Cyber Governance Code of Practice sets out clear expectations for board-level ownership of cyber risk. It’s backed by the National Cyber Security Centre and includes training and toolkits to help directors integrate cyber governance into strategic decision-making.  

Across the EU, the Digital Operational Resilience Act (DORA) and NIS2 Directive impose direct accountability on boards of financial and critical infrastructure entities. These laws require directors to oversee ICT risk management, resilience testing, and incident reporting, with potential penalties for non-compliance.  

These frameworks signal a clear shift: cyber security is no longer just an IT issue—it’s a boardroom issue. Directors can no longer delegate oversight and hope for the best. They must be proactive, informed, and prepared to answer for failures. 

And so, the CISO becomes both the shield and the lightning rod. You defend the organisation but also absorb its fear. Every decision carries personal risk. Every “what if” becomes a weight that never truly lifts. 

 

 

The human cost of constant vigilance 

The mental and emotional strain of leading cyber defence rarely gets discussed outside closed doors. Many CISOs live in a state of continuous alertness, a kind of professional hypervigilance. Even when the systems are quiet, the mind is not. 

The pressure doesn’t end at the office door. It follows you home, interrupts sleep and can gradually erode health and happiness. The late-night notifications. The weekend incident calls. The constant anxiety that something, somewhere, has slipped past unseen. 

And it’s not just about fear of the breach itself. It’s the fear of what follows. The scrutiny, the finger-pointing. It’s a precarious position, and one that too often isolates the very people responsible for keeping everyone else safe. 

 

 

Resilience, but at what cost? 

In cyber security, we talk endlessly about resilience. We measure it in recovery times, redundancies, and risk scores. But rarely do we talk about the cost of resilience – the toll it takes on those who must embody it day after day. 

Resilience for a CISO isn’t just a professional quality. It’s a survival mechanism. It means managing fear without letting it control you. It means making calm, strategic decisions in the middle of chaos. It means staying composed when others panic and showing strength when you might feel anything but strong. 

Over time, that can take something from you. The stoicism that protects your team can become a mask that hides exhaustion. The drive to maintain control can edge dangerously close to burnout. And when a role requires constant readiness, genuine rest becomes rare. 

 

Leadership in uncertainty 

The best CISOs don’t promise that their organisation will ever be attacked (that’s impossible), instead they build organisations that can withstand them. They communicate risk with honesty, not fear. They bridge the gap between technology and business reality.  

In moments of crisis, what defines a leader isn’t whether an attack happened, but how they respond. Calm under pressure and keeping your head when everyone else is losing theirs. Integrity when blame starts to fly. Those are the measures that matter even if they’re not always recognised. 

 

 

How Integrity360 helps lighten the load 

No CISO should have to carry that burden alone. That’s where Integrity360 can help. As one of Europe’s leading independent cyber security specialists, we partner with CISOs to reduce operational strain, strengthen resilience, and provide trusted support before, during, and after incidents. 

Our services – from Managed Detection and Response (MDR) and Incident Response to Cyber Risk and Compliance Advisory – are designed to give leaders confidence that their organisation’s defences are being continuously monitored and optimised. With Integrity360’s teams of cyber experts on your side, you’re not just reacting to threats; you’re proactively identifying, containing, and remediating them before they escalate. 

Through services like Continuous Threat Exposure Management (CTEM), CyberConnect360, and Managed dSOC, we help CISOs maintain control, fill in any skills gap in their teams, communicate clearly with the board, and demonstrate measurable improvement in security posture. We act as an extension of your team that provides insight, assurance, and the technical depth needed to stay one step ahead. 

Perhaps most importantly, we help leaders reclaim peace of mind. When you know there’s a trusted partner watching over your environment 24/7, you can focus on strategy, leadership, and people, not firefighting every alert. 

 

Looking after those who protect 

If you know a CISO, check in on them. They may not say it, but the burden they carry is heavy. Beneath the calm professionalism and technical expertise, there’s a human being constantly weighing impossible odds. A simple conversation, a word of appreciation, or an acknowledgment of their pressure can make a real difference. 

And if you are a CISO, remind yourself that your worth is not tied to whether you stopped every attack. Your value lies in your leadership – in the way you anticipate, adapt, and guide others through uncertainty. 

Cyber security is never about perfect defence. It’s about continuous learning, relentless commitment, and courage in the face of the unknown. The truth is, you can do everything right and still face a breach. But that doesn’t diminish what you’ve achieved, or the difference you make every day in keeping the digital world a little safer. 

The sad truth every CISO knows is that blame often follows the breach. The deeper truth, though, is that leadership in this space has always been about standing firm despite that reality – and with the right support from partners like Integrity360, no CISO has to stand alone.
