Under Attack?
Cyber security incidents don’t clock in at 9 and clock out at 5. They strike whenever a weakness is found – whether it’s a misconfigured cloud service, a successful phishing attack, or a zero-day exploit. And when they do, the speed and efficiency of your response can mean the difference between a manageable incident and one with catastrophic business consequences.
That’s where an Incident Response (IR) Retainer comes in.
Many organisations understand the importance of incident response. They may even have a basic plan in place. But when the moment comes – a real-world ransomware attack, a suspected compromise, or data breach – time, expertise and clarity are often in short supply. An IR retainer bridges that gap, putting expert responders on standby and reducing the impact of a breach before it spirals out of control.
What is an incident response retainer?
An IR retainer is a pre-arranged agreement with a cyber security provider that guarantees access to their incident response team in the event of a cyber attack. Unlike ad-hoc services that may involve time-consuming contracts and availability concerns, an IR retainer ensures immediate action, defined service levels, and priority support when it’s needed most.
But not all IR retainers are created equal.
A high-quality IR retainer should go beyond simple availability. It should act as a proactive partnership, helping organisations build resilience before an incident occurs, and supporting recovery after the dust settles.
Why your business should have one
Cyber threats are evolving in scale and complexity. Ransomware gangs, state-backed actors, insider threats and highly targeted phishing campaigns are no longer reserved for global giants. SMEs and mid-market organisations are now prime targets – and often the least prepared to respond.
Many lack the internal skills or resources to investigate, contain and eradicate an attack quickly. The delay in response not only amplifies the damage but can also increase legal, reputational and regulatory risks. Many businesses also lack the capacity to keep their incident response plans up to date or test them regularly, leaving them vulnerable when an attack occurs.
An IR retainer helps bridge that gap by:
- Providing fast access to experienced incident responders
- Helping contain and remediate attacks with minimal disruption
- Ensuring compliance with key frameworks like ISO/IEC 27001, NIST, and COBIT
- Offering forensic and malware analysis, reporting and board-level communication
- Supporting readiness and recovery activities to reduce risk going forward
In short, it offers peace of mind and demonstrable resilience in the face of ever-evolving cyber threats.
Five key components of an effective IR retainer
If you’re evaluating IR retainers, don’t just ask whether you’ll get support. Ask what that support looks like, how it’s delivered, and whether it aligns with your organisation’s risk profile. Here are five key components every effective IR retainer should include:
- clear service-level agreements (SLAs)
Speed is everything in incident response. A good retainer defines exactly what support is included, how fast the provider will respond, and how your hours or credits can be allocated. Transparency around deliverables, escalation paths, and costs is essential – especially when every minute counts. - 24/7/365 availability
Threat actors don’t take holidays. Your IR provider must be reachable around the clock with a guaranteed response time – whether it’s 3am on a Saturday or 9am on a Monday. Anything less is a risk your business can’t afford to take. - tailored services that reflect your threat landscape
Your organisation isn’t a carbon copy of the next. Whether you're in finance, healthcare or retail, your threat profile will be different. Your IR retainer should include services that reflect your reality – whether that’s ransomware negotiation, investigation of business email compromise (BEC), or support during DDoS mitigation. - support for IR planning and readiness
It’s not just about the response. Preparation is critical. A good retainer includes help with IR plan development, tabletop exercises, and readiness assessments. These ensure your teams know how to act, what their roles are, and how to engage the retainer quickly and effectively. - guidance on security posture hardening
IR isn’t just about fixing things when they go wrong – it’s also about preventing incidents before they happen. The right partner will help you identify exposures, close gaps in your defences, and implement changes that make you a harder target for attackers.
