What Is It, Why It Matters & How to Choose the Right Partner
In today’s digital landscape, organisations face a relentless array of cyber threats, from ransomware to data breaches. Without a well-prepared strategy to manage these incidents, businesses risk severe financial losses, reputational damage and prolonged operational downtime.
Incident response (IR) is a crucial part of cyber security planning, enabling organisations to swiftly detect, contain and recover from attacks. However, the effectiveness of an IR strategy often hinges on the expertise of the response provider—a partner who offers end-to-end support, from incident planning to post-incident recovery.
This Guide to Incident Response will equip you with insights on building a resilient IR strategy, understanding key response components and choosing the right partner to safeguard your organisation.
What Is Incident Response?
Incident response (IR) is a structured approach to identifying, managing and resolving cyber security incidents such as data breaches, ransomware attacks or unauthorised access to sensitive systems. The primary objective of Incident Response is to contain and neutralise threats as quickly as possible to minimise damage and return to normal operations. An effective IR Plan includes clear protocols and communication strategies, enabling teams to act swiftly and reduce potential disruptions, financial impacts and regulatory penalties.
Incident response is more than a reactionary measure—it’s a proactive framework that helps organisations prepare for incidents and maintain resilience. Key phases of Incident Response typically include:
1. Preparation: Developing and implementing policies, procedures and training to prepare for potential incidents.
2. Detection & Analysis: Identifying and assessing the nature and extent of an incident.
3. Containment, Eradication & Recovery: Containing the threat, removing the attacker’s access and restoring affected systems.
4. Post-Incident Activities: Reviewing and analysing the incident to improve defences and prevent recurrence.
By having a comprehensive IR plan, organisations can significantly reduce the impact of cyber incidents and quickly restore normal operations.
Why Is Incident Response Essential?
Incident response is critical for business continuity and regulatory compliance. Without a solid IR plan, organisations risk prolonged recovery times, regulatory penalties and reputational damage.
Additionally, many regulatory standards, such as ISO 27001, mandate that organisations have IR processes in place. An effective IR provider not only assists in the immediate management of incidents but also helps organisations meet these regulatory standards, which can be essential for avoiding legal complications.
Moreover, a strong incident response plan can play an important role in cyber insurance claims. Insurers are increasingly requiring evidence of proactive security measures, including IR plans, before issuing or renewing policies. Organisations without a prepared and experienced IR partner may find it challenging to secure a policy payout following a breach.
What to Look for in an Incident Response Partner
Choosing the right Incident Response (IR) provider is critical for ensuring that your organisation can effectively detect, contain and recover from cyber security incidents.
Here are the top qualities to consider:
1. Accreditation and Industry Expertise
A top-tier IR provider should have industry-recognised certifications that confirm their expertise and adherence to best practices. Key accreditations to look for include NCSC Assured Provider status and CREST Accreditation.
- NCSC Assured Provider: Certification from the National Cyber Security Centre (NCSC) ensures that the provider has undergone rigorous vetting and is approved to handle sensitive, high-stakes incidents. This designation signifies the provider’s commitment to technical excellence, compliance and effective incident management.
- CREST Accreditation: CREST-accredited providers are validated in areas like SOC and Pen Testing, essential skills for diagnosing and responding to incidents accurately. Providers such as CyberOne, which hold both NCSC and CREST certifications, bring a high level of expertise and trust, ensuring a rapid, compliant and effective response across various industries.
2. 24×7 Availability
Cyber incidents can occur at any time, so it’s essential to work with a provider who offers round-the-clock support. A true IR partner will provide 24×7 availability, ensuring that incidents are promptly addressed, even during weekends or holidays. Continuous availability minimises the risk of an undetected or delayed response, which could otherwise lead to escalating damage.
3. Network Operations Centre (NOC) Capabilities
Strong IR providers have dedicated Network Operations Centre (NOC) capabilities, providing constant monitoring to enable quick detection, containment and recovery during an incident.
NOC support ensures that incidents are managed immediately, preventing minor disruptions from escalating and addressing broader network issues as they arise.
For organisations without an in-house 24×7 team, NOC services close critical coverage gaps and alleviate reliance on internal resources—particularly valuable during holidays and outside of core hours.
4. Comprehensive Planning, Training & Playbook Development
Effective incident response goes beyond reactive support; it starts with a detailed plan, team training and well-defined playbooks. The best IR providers assist organisations in building and testing a tailored incident response plan that is specifically adapted to their environment and potential threats.
- Customised Incident Response Plan: An experienced IR provider will work closely with your organisation to create a comprehensive IR plan that aligns with your unique risk landscape and compliance requirements. This plan should cover everything from escalation protocols to communication strategies, ensuring that all team members know their roles and responsibilities.
- Tabletop Exercises & Simulations: Regular tabletop exercises allow teams to simulate various attack scenarios and test the IR plan in a controlled, low-stakes environment. By mimicking real-world incidents, tabletop exercises enable teams to practice executing the IR plan, identify potential weaknesses and improve response times. Providers like CyberOne often tailor these exercises to an organisation’s specific risks, enhancing the team’s readiness and coordination across departments.
- Playbook Creation: Playbooks provide step-by-step guidance for responding to specific incident types, such as phishing, ransomware or data exfiltration. They contain predefined procedures for containing threats, gathering evidence and communicating with stakeholders, ensuring consistency and efficiency during incidents. A skilled IR provider will work with your organisation to create tailored playbooks that align with your security policies and compliance obligations, enabling responders to act quickly and accurately under pressure.
- Ongoing Training: Continuous training is critical to keeping your team prepared for emerging threats and new attack methods. Top providers offer tailored training sessions for both security and non-security staff, teaching everyone to recognise potential threats, understand escalation paths and follow IR protocols. This proactive approach ensures that everyone in your organisation is ready to contribute effectively to incident management when the need arises.
5. Proactive Threat Intelligence
Proactive threat intelligence is essential to staying one step ahead of attackers. Leading IR providers employ threat intelligence teams that monitor the latest tactics, techniques and procedures (TTPs) used by cybercriminals. By analysing data from global threat intelligence feeds and sources such as Microsoft Sentinel, providers can detect patterns and potential vulnerabilities in your organisation’s environment before they are exploited.
Threat intelligence helps your organisation proactively secure weak points and adjust defences to emerging threats, significantly reducing the risk of incidents. Additionally, continuous threat intelligence informs updates to your IR plan, ensuring it reflects the latest attack methods and vulnerabilities. With providers like CyberOne, this proactive approach to monitoring and managing threats strengthens your resilience and security posture.
6. Post-Incident Review and Recovery Support
An incident does not end once the immediate threat is contained; in fact, the post-incident phase is critical for strengthening your organisation’s defences. A reputable IR provider will conduct a thorough post-incident review to identify what went well, where there were challenges and what improvements can be made to prevent future incidents.
- Post-Incident Analysis: This review involves analyzing how the incident occurred, assessing response effectiveness and evaluating areas for improvement. The provider will provide a detailed incident report outlining all findings and any recommendations to enhance your security framework.
- Long-Term Recovery and Lessons Learned: In addition to the immediate analysis, the provider should support long-term recovery efforts, such as implementing additional security measures, updating policies and providing refresher training. This continuous improvement process strengthens your organization’s resilience, ensuring that future incidents are managed more efficiently and with less disruption.
By selecting an IR provider with these essential qualities—accreditation, 24×7 availability, NOC support, comprehensive planning and tabletop exercises, proactive threat intelligence and post-incident review and recovery support—your organisation will be prepared to handle cyber incidents effectively and maintain a strong security posture in an evolving threat landscape.
