Definition

What is incident response?

Incident response means intervening quickly when an information system is under attack, or suspected to be, in order to understand what's happening, limit the impact, and bring the systems back to a working state.

Ransomware, account compromise, network intrusion, data exfiltration, a successful phishing attempt... every incident is different, but all of them require a rigorous method to avoid making the situation worse or losing useful evidence.

We intervene remotely or on-site, in France, to qualify the incident, contain the attack, investigate it thoroughly, and support you through remediation and, if needed, crisis communication.

A rapid response

Why speed matters

The first hours after an incident are the ones that decide how bad it gets. Acting fast, and acting correctly, limits the damage and often makes the difference between a contained incident and a full-blown crisis.

Limit the financial and reputational damage by containing the attack before it spreads further
Preserve the digital evidence needed for a complaint or an insurance claim, which is easily lost if handled incorrectly
Meet your regulatory notification deadlines where they apply (such as the 72-hour GDPR breach notification)
Reassure your teams, your clients, and your insurer with a clear, methodical response

Our intervention method

1. Qualification

3. Investigation & remediation

In-depth analysis of the incident, root cause identification, and implementation of corrective actions.

4. Report & lessons learned

Delivery of an intervention report detailing the incident, the actions taken, and recommendations to prevent it from happening again.

FAQ

Frequently asked questions

How fast can you intervene?

As soon as you contact us, we start with a quick qualification call to assess the severity of the situation and decide whether a remote or on-site intervention is needed. Response times depend on our current availability and the criticality of the incident.

Do you intervene remotely or on-site?

Both. Many incidents can be handled remotely. When needed, we can intervene on-site in France, particularly for physical containment or complex investigations.

What should we do immediately after discovering an incident?

Avoid shutting down or wiping affected machines before isolating them from the network, as this can destroy evidence needed for the investigation. Contact us as soon as possible so we can guide you step by step.

Can you help us file a police complaint?

Yes. We help preserve the digital evidence needed to support a complaint, and we can guide you towards the relevant authorities depending on the nature of the incident.

Is the intervention covered by cyber insurance?

It depends on your insurance contract. We recommend checking with your insurer beforehand, and we can work alongside them if your policy requires a specific process.

Do we need an existing contract with you to get help urgently?

No. We can intervene without a prior relationship, though having one in place beforehand generally means a faster response, since we already know your environment.

How is an incident response intervention billed?

Billing depends on the duration and complexity of the intervention. We give you visibility on the estimated cost as early as possible in the process.
