24/7 emergency response
Emergency Incident Response
Neutralizing what you can see is not containment. Our incident response engagements run the full chain — detect, contain, eradicate, recover — and do not close until we understand how the actor got in, what they touched, and what would let them back. Assured response within four hours of first contact.
Containment is not the finish line
Isolating the host that tripped the alert stops the symptom you can see. It does not tell you how the actor got in, which credentials they took, what else they touched, or whether the access that let them in is still open. Incidents that are closed at the symptom are the ones that recur a month later.
How an engagement runs
First contact starts the clock: we are working your incident within four hours. We begin remote volatile-memory capture and forensic acquisition immediately, because the evidence that answers the hardest questions is the evidence that disappears first. From there we run the full chain — detect, contain, eradicate, recover — reconstructing the attack path as we go rather than reporting on it afterwards.
Getting you back to work
Recovery is guided, not handed over. We stay through eradication and restoration, verify that the access path is genuinely closed, and hand you a report your board, insurer and regulator can all read — followed by the hardening work that stops a repeat.

Common questions
What is incident response?
Incident response is the structured process an organization follows to detect, contain, eradicate and recover from a cyber attack, and to establish how the attacker got in and what they accessed. A complete response does not stop at isolating the affected system: it reconstructs the full attack chain, because an incident closed at the symptom is the one that recurs.
What is DFIR?
DFIR stands for digital forensics and incident response — the combined discipline of collecting and analysing digital evidence (forensics) and managing an active cyber attack end to end (incident response). The two are treated as one practice because the evidence that answers the hardest questions during an incident, such as volatile memory, is the evidence that disappears first.
How quickly can an incident response team start work?
IONSEC begins working an incident within four hours of first contact, 24 hours a day, every day of the year. Forensic acquisition and volatile-memory capture are performed remotely, which is what makes that response time achievable regardless of where the affected systems are.
What should we do first if we think we have been breached?
Contact an incident response team before you start remediating, and preserve the affected systems in place if you can. Rebuilding, reimaging or powering off a compromised machine destroys the volatile evidence needed to establish how far the attacker got and what they took.
Should we shut down or disconnect a compromised computer?
Do not power off a compromised machine — shutting it down destroys the contents of memory, which is often where the only evidence of the attack lives. Disconnecting it from the network to stop lateral movement is usually safe and preferable, but confirm with your responders first, as some malware reacts to losing connectivity.
We think we are compromised right now. What do we do?
Contact us before you start remediating — rebuilding or reimaging destroys the evidence needed to establish scope. Use the emergency line and preserve the affected systems in place if you can.
Do you need to be on site?
Usually not. Acquisition and analysis are performed remotely, which is what makes the four-hour response possible. On-site support is available where the environment requires it.
Do you work with our insurer and legal counsel?
Yes. We are used to working under counsel direction and to producing reporting that meets insurer and regulatory evidentiary expectations.
How long does an incident response engagement take?
The containment phase of an incident is usually measured in days, while full attack-chain reconstruction, eradication and guided recovery typically run for several weeks depending on how far the actor got and how large the estate is. The engagement does not close until the access path that let the attacker in is verified as shut.
