Incident Response Retainer

A serious cybersecurity incident rarely happens at a convenient time. It may begin outside normal working hours, affect several systems at once, or require specialist expertise that is not available internally at short notice.

Searching for external support after an incident has already started can cause further delay. Commercial terms, access arrangements, confidentiality requirements, communication channels, and technical responsibilities may all need to be agreed while the organisation is already under pressure.

An Incident Response Retainer from CA gives your organisation prearranged access to experienced incident response and digital forensics specialists. We prepare with your teams before an incident occurs so that support can begin more quickly, responsibilities are understood, and the response is coordinated from the first stages of the event.

Why This Matters

The first hours of a cybersecurity incident can influence its overall impact. Delays may allow an attacker to maintain access, move between systems, collect additional information, or cause further disruption.
Internal teams may also face decisions that they do not make regularly. They may need to determine whether to isolate an important server, disable a privileged account, preserve a device for forensic analysis, notify a supplier, or interrupt a business service.
Without a prepared relationship, valuable time can be lost finding the right specialists and explaining the organisation’s environment from the beginning.
An incident response retainer helps you:

🎯

Access specialist support more quickly

Use an agreed activation process to involve incident response and forensic specialists when urgent assistance is required.

📊

Respond through prepared arrangements

Establish contacts, responsibilities, communication channels, access requirements, and escalation routes before an incident occurs.

🛡️

Make better decisions under pressure

Give technical teams and business leaders access to experienced support when containment, investigation, communication, and recovery decisions must be made quickly.

🤝

Improve readiness throughout the year

Use preparation activities, reviews, and exercises to strengthen internal response capabilities before they are tested by a real event.


Our Approach

We do not treat an incident response retainer as an emergency telephone number with no preparation behind it. The value of a retainer comes from establishing a working relationship and understanding the organisation before urgent help is needed.
Our approach combines pre-incident preparation with access to investigation, containment, digital forensics, recovery support, and post-incident improvement.
The service is adapted to the organisation’s technology environment, business priorities, internal capabilities, geographic coverage, regulatory obligations, and existing incident response arrangements.

1

Prepare the engagement and understand the environment

We begin by learning about the organisation’s essential services, technology environment, key systems, sensitive information, internal teams, suppliers, and existing security capabilities.
We identify the people who can activate the service, approve important actions, provide technical access, communicate with management, and involve legal, regulatory, insurance, or external parties where required.
Practical arrangements are established in advance. These may include secure communication channels, escalation contacts, evidence-transfer methods, system access requirements, confidentiality arrangements, and procedures for working with other service providers.
We also review existing incident response plans, network and system information, logging capabilities, forensic readiness, backup arrangements, and known operational limitations.
This preparation reduces the amount of basic information that must be gathered during an active incident.

2

Establish activation and response procedures

We define a clear process for activating the retainer and bringing the appropriate specialist resources into the response.
The procedure explains who can request support, how urgency is assessed, which information should be provided, and how communication will be maintained after activation.
We also define the initial response stages. These may include triage, confirmation of the incident, preservation of volatile evidence, identification of affected systems, immediate risk reduction, and development of an investigation plan.
Responsibilities between CA, internal teams, managed service providers, cloud providers, insurers, legal advisers, and other involved parties are clarified wherever possible.
This helps prevent confusion during an incident and reduces the risk of important tasks being duplicated, delayed, or overlooked.

3

Provide coordinated incident response and forensic support

Once the retainer is activated, we help the organisation establish control and understand the developing situation.
Our specialists analyse available alerts, logs, accounts, devices, network activity, cloud services, applications, and other relevant evidence. We help determine the likely attack route, affected systems, activity performed by the attacker, and whether the threat remains active.
Containment actions are recommended according to the available evidence and potential business impact. These may include isolating devices, disabling accounts, blocking connections, restricting access, preserving evidence, or applying temporary safeguards to critical services.
We also support recovery planning. Systems can be prioritised according to business need, tested before returning to normal use, and monitored for signs of renewed suspicious activity.
Throughout the response, important findings, decisions, actions, and open questions are documented.

4

Review readiness and improve after incidents

The retainer supports preparation as well as emergency response.
Regular reviews can consider changes to systems, cloud platforms, suppliers, contacts, legal obligations, business services, and internal responsibilities. This helps ensure that the activation and response arrangements remain current.
Tabletop exercises and practical scenarios can be used to test decision-making, escalation, communication, evidence preservation, containment, and recovery. The purpose is to identify gaps before a real incident places the organisation under pressure.
After an incident, we document the findings and support a structured review. This identifies technical and organisational improvements relating to security controls, monitoring, access, vulnerability management, backups, supplier oversight, communication, and response procedures.
The lessons are converted into clear actions so that readiness improves after each exercise or incident.


What Sets CA Apart

💬

Preparation before urgent support is needed

We learn about the organisation, establish working arrangements, and clarify responsibilities before an incident occurs.

🛡️

Integrated response and digital forensics

Investigation, evidence preservation, containment, recovery, and reporting are coordinated as parts of the same response.

🤝

Business-aware decision support

We consider the operational impact of isolating systems, disabling accounts, interrupting services, and changing recovery priorities.

⚖️

Readiness throughout the retainer period

The service can include reviews, exercises, planning, and improvement activities rather than remaining unused until an emergency occurs.


The Business Value

An Incident Response Retainer from CA gives your organisation greater confidence that specialist help will be available when a serious cybersecurity incident occurs.
Prearranged commercial, technical, and communication processes reduce delays at the beginning of the response. Internal teams do not need to search for an available provider while also trying to contain an active threat and protect business operations.
Specialists who already understand the organisation can move more quickly towards the important questions. This includes determining what happened, which systems are affected, whether the attacker remains active, and which containment measures are appropriate.
The retainer also strengthens internal readiness. Reviews and exercises help employees understand their responsibilities, identify weaknesses in existing procedures, and practise difficult decisions before a real incident occurs.
The result is faster access to specialist support, more coordinated containment and investigation, safer recovery, and an organisation that is better prepared to manage a high-pressure cybersecurity event.


Next Step

The best time to arrange incident response support is before the organisation needs to use it.
