Why cyber breach response defines business survivial
Cyber breaches are no longer rare. They are escalating, unavoidable, and every organisation must be prepared. These attacks are costly, disruptive, and increasingly public. Senior leaders must treat breach response as a core business capability, not just an IT concern.
According to IBM’s 2025 Cost of a Data Breach Report, the average UK data breach now costs over £3.5 million. Prevention remains vital, but response determines survival.
Major companies face costly cyber disruptions
Recent cyber-attacks have exposed the financial and operational vulnerabilities of some of the UK’s most recognisable brands. Marks & Spencer endured weeks of disruption to core systems, resulting in reputational damage and lost customer confidence. Co-op Group reported £206 million in lost sales after ransomware halted retail operations, highlighting the scale of commercial impact. Jaguar Land Rover faced production delays and recovery costs linked to compromised manufacturing infrastructure, while Adidas confirmed a customer data breach that raised serious concerns around data governance and consumer trust. Brussels Airport was also targeted by ransomware, prompting the European Union Agency for Cybersecurity (ENISA) to issue operational warnings about aviation infrastructure.
These incidents share a common theme: while prevention remains essential, the true measure of resilience lies in how effectively organisations respond once an attack occurs.
Why security leaders struggle with breach response
Security teams tend to focus on prevention, which is what’s known as “left of boom” activity.
Understanding Left of Boom vs Right of Boom
Left of Boom includes:
- Zero-day malware detection
- Stolen credentials monitoring
- Fraudulent activity detection
- Failed audit remediation
- Compromised cloud app security
- Ransomware protection
Despite these measures, breaches still occur. When they do, organisations move “right of boom”, the critical phase after an attack.
Right of Boom challenges include:
- Malware spreading across systems
- New compromises discovered
- Press conferences and public statements
- FCA investigations and scrutiny
- Insider threat management
- Victim notification processes
- Coordinating response websites
The crisis response gap
Security and IT teams excel at prevention. These tasks are routine and measurable. Crisis response, however, involves legal, HR, and board-level coordination areas where uncertainty dominates. Few teams practise these scenarios, leading to confusion and miscommunication when real incidents occur. This gap between technical prevention and organisational response is where most companies fail.

As organisations build response capabilities, new technologies are accelerating what’s possible.
Artificial intelligence is transforming how organisations manage breach response. It accelerates detection, automates containment, and improves decision-making under pressure.
AI-driven tools can identify anomalies and zero-day threats faster than manual systems, reducing the window for attackers. Machine learning models analyse large data sets to uncover patterns that indicate ongoing breaches, often before human teams detect them.
Automation powered by AI enables rapid response actions such as isolating compromised devices, blocking malicious traffic, and triggering communication protocols. This helps maintain operational continuity and reduces response time dramatically.
AI also supports post-incident analysis, revealing attack vectors and recommending improvements to playbooks. Integrating AI into your cyber breach response plan is now essential for organisational resilience.
Your cyber breach response plan needs practice
A crisis response plan that sits unused is a liability. Regular practice exercises reveal weaknesses before real attacks occur. Simulations expose communication gaps and clarify stakeholder roles. Schedule quarterly breach response rehearsals involving legal, HR, and executive teams. Test notification procedures, decision trees, and escalation paths. Document and review lessons after each exercise.
Most organisations never practise their playbooks, which explains why breach response often fails.
Three critical lessons from cyber breach response
Lesson 1: Culture counts
Security culture determines breach response success. Teams must trust each other during crises.
Build cross-functional relationships before breaches happen. Security, legal, HR, and communications teams should know each other well. Board members need regular security briefings.
Strong culture breaks down silos, speeds up decisions, and reduces confusion when under pressure.
Lesson 2: Playbooks crack under pressure
Written procedures often fail during real incidents. Stress changes how people act and think.
Your playbook makes assumptions that may not hold true. Attackers don’t follow your script, and systems can fail unpredictably.
Develop flexible frameworks instead of rigid checklists. Train teams to adapt under pressure and test your playbook with realistic, high-stress scenarios. Identify breaking points before attackers do.
Lesson 3: Leadership matters
Executive leadership determines breach response outcomes. CISOs cannot handle crises alone. CEOs, board members, and CFOs must all understand their roles during incidents. Their decisions shape customer trust, regulatory outcomes, and financial recovery. Invest in leadership training for security incidents. Executives need breach response skills as much as technical teams do.
Build your cyber breach response capability now
Senior leaders face a choice: wait for a breach to expose weaknesses, or prepare now.
Start with an honest assessment:
- Does your team regularly practise response scenarios?
- Do executives know their crisis roles?
- Can departments coordinate effectively under pressure?
Create a rehearsal schedule, include all key stakeholders, and act on identified gaps. Build trust across departments now, before it’s urgently needed.
Breach prevention alone cannot protect your organisation. Response capability is equally critical.
Take action on your cyber breach response plan
Contact security experts experienced in crisis management. Review your current playbooks with professionals who understand real-world breach dynamics. Schedule your first breach response exercise within 30 days. Your organisation will face a cyber breach eventually, statistics confirm this reality. How you respond determines the ultimate cost.
Prepare now or pay later. The choice belongs to senior leadership.
