Why organisations outsource incident response

During an incident, no one knows exactly what to do

No rehearsed playbooks, no crisis management protocol, no communications template. Half the team freezes, the other half is overwhelmed. Hours pass without clarity. While damage compounds by the minute.

External IR teams react too late

Without a retainer, average wait time is 24 to 72 hours. In that window the attacker spreads further, ransomware encrypts more systems and volatile evidence vanishes. Responding in hours instead of days often saves millions.

Forensic evidence doesn't hold up at the insurer or in court

Insurers reject claims when chain-of-custody is missing. Criminal cases stall on procedural errors. Perpetrators stay invisible. Forensic work done under pressure without protocol is worthless after the fact.

No external handover, no waiting time, no process gap between detection and response.

Frequently Asked Questions

FAQ

How fast can DEFION respond to an incident?
With a retainer: within 2 hours. Without a retainer: as fast as possible, typically within 4–8 hours. 24/7, across Europe.
What is the difference between IR and Digital Forensics?
Incident Response focuses on containment and recovery. Digital Forensics focuses on evidence and reconstruction. We often combine both.
What does an Incident Response Retainer cost?
It depends on response time and scope. A retainer guarantees DEFION is immediately available. You pay a monthly fee plus any actual engagement hours.
What is a Compromise Assessment?
A forensic investigation to determine whether an attacker is already active in your network. We look for signs of compromise that standard monitoring misses.
Can DEFION respond in Spain as well?
Yes. DEFION has offices in Zoetermeer and Barcelona. Incident response is available across Europe, including on-site deployment where needed.
