What our DFIR services include

How our DFIR services work

Our global CSIRT brings decades of frontline experience, mastering complex breaches worldwide. Our experts, from threat hunters and ethical hackers to security researchers, constantly analyze evolving TTPs. This deep expertise directly informs how we execute each phase of your incident response.

1

Preparation

We evaluate your network and security systems to develop an incident response plan, including detailed playbooks and communication strategies, ensuring you’re prepared ahead of time for an incident.

2

Identification

We precisely gather and analyze security events, allowing us to confirm incident status. We then define the scope of work and select the appropriate process, ensuring rapid and accurate threat assessment.

3

Containment

Our teams act quickly to halt further damage, produce forensic images (copies of digital evidence), collect and examine evidence to assess containment, and compile intelligence to develop indicators of compromise (IOCs).

4

Eradication

Thoroughly removing the incident’s root cause is our next step. We eliminate malicious code, reverse unauthorized system changes, enforce password resets, implement IP blocking, etc. for a clean, secure environment.

5

Recovery

Our teams will restore your systems to normal operation, implement system hardening and other safeguards to prevent future incidents, and closely monitor any security threats to ensure online services are fully reinstated.

6

Follow-up

Finally, we document actions taken during all phases. We conduct a comprehensive post-incident review, identifying lessons learned and recommending strategic actions to strengthen your long-term security.
