When an incident is under way, containment comes first: we stop the spread, preserve the evidence, work out what happened and restore operations in a defined order.
Analysis of logs, accounts, email and endpoints to reconstruct the attack
Eradication of the attacker's access and recovery of services
Technical communication with leadership while the incident is open
Post-incident report with causes and recommendations
This is for you if
You suspect unauthorized access to accounts, email or servers
Your files appeared encrypted or a ransom note is showing
You want to review your response plan before you need it
How we do it
1
Contain
We isolate what is affected and cut the attacker's access without destroying evidence.
2
Investigate
We reconstruct what happened, how they got in, what they touched and which data may have been exposed.
3
Eradicate and recover
We close the way in, clean up and bring services back in the order your business needs.
4
Learn and strengthen
We document the incident and leave a plan so it does not happen again through the same route.
An incident, moment by moment
Walk through an illustrative incident, from an email to the data, and see at each moment what can be contained, what evidence exists and what the team does.
Illustrative simulationIt is an example incident: it matches no client and its times are not a response commitment or an SLA.
Slide or use the arrow keys. Times are hours and minutes since the initial access.
00:00since the initial access
Initial access by email
Containment
What can be stopped
No intrusion is confirmed yet. Isolating the message and the devices that opened it prevents the next step.
Evidence
What evidence exists
The original email with its headers, the mail server logs and the list of who received it.
Action
What the team does
Triage: confirm what happened, preserve evidence from the first moment and tell whoever decides.
00:27since the initial access
Compromised credential
Containment
What can be stopped
The account can be blocked, active sessions closed and credentials reset before they are used on other systems.
Evidence
What evidence exists
The account's sign-in logs, where the accesses came from and the activity in the mailbox.
Action
What the team does
Contain the affected account and analyze logs and accounts to learn whether the credential was used, and from where.
01:40since the initial access
Privilege escalation
Containment
What can be stopped
Isolate the devices involved and cut the attacker's access to accounts with more permissions.
Evidence
What evidence exists
Changes to accounts and permissions, and the logs of the devices and servers the attacker moved through.
Action
What the team does
Isolate without destroying evidence, reconstruct the route taken and begin removing the attacker's access.
03:15since the initial access
Data access
Containment
What can be stopped
Close the exit routes and protect the data not yet reached.
Evidence
What evidence exists
File access and transfer logs, which show which data may have been compromised.
Action
What the team does
Brief leadership with technical clarity, eradicate the access, restore services and prepare the post-incident report.

Frequently asked questions
There is an incident under way. What do I do first?
Disconnect the affected machines from the network, keep everything you see (ransom notes, emails, logs) and contact us before shutting down, wiping or reinstalling. Those actions can destroy useful evidence.
Should we pay the ransom?
It is a business and legal decision that we do not make for you. We give you the technical facts to decide: what was encrypted, whether usable backups exist and what the risk of data exposure is.
Can you recover my encrypted files?
It depends on the case: on the variant, on the available backups and on what can be restored. We assess it from the first analysis and tell you what is possible. Cyber Recovery is a service of its own.
