Not understanding is a major risk
When an incident occurs, many organisations restore services urgently without knowing how the attack happened, whether the attacker is still present, or whether evidence has been preserved.
Without forensic analysis, the risk of recurrence is high.

Traceability of all actions taken
Establish facts, not assumptions
Forensic analysis aims to precisely reconstruct how the attack unfolded, identify the entry point, understand the attacker's actions, and measure the real impact on the information system.
We move from hypothesis to evidence.
- Securing impacted environments
- Preservation of digital evidence
- Analysis of logs, workstations and servers
- Identification of attack mechanisms
- Clear timeline of events
Before any intervention on a disk or VM: preserve the evidence
One of the fundamental principles of digital forensics is to guarantee the integrity and admissibility of evidence. TYSCO never intervenes directly on the original media. Before any analysis, our experts apply a strict preservation protocol.
Every piece of evidence is timestamped, sealed and traceable end-to-end.
Clear conclusions, not an incomprehensible report
At TYSCO, conclusions are clear, risks are explained, and recommendations are actionable. Management can understand and decide.
01
Investigation
In-depth analysis of impacted systems and activity logs.
02
Reconstruction
Precise reconstruction of the attack timeline and attacker actions.

Assessment
Measurement of the real impact and verification that no persistence remains.
04
Recommendations
Clear action plan to strengthen protections and prevent recurrence.
A decisive advantage after a ransomware attack
After a ransomware attack, forensic analysis verifies the absence of persistence, confirms the cleanliness of restored environments and explains how the encryption was possible.
We don't just restart — we secure for the long term.
