Incident response and digital forensics (DFIR) specialists

Digiventi provides incident responders who join your team during suspected breaches or active attacks. They assess available telemetry and establish an incident timeline, separating confirmed compromise from alerts that still need validation.

For ransomware or hands-on-keyboard intrusions, specialists trace attacker activity and recommend containment boundaries. They can isolate affected endpoints, revoke compromised sessions, block malicious indicators and coordinate evidence capture before destructive changes. Response decisions account for business dependencies and the risk that containment could interrupt essential services.

Digital forensics analysts reconstruct activity when the cause or extent of an incident remains uncertain. Evidence handling includes acquisition records and cryptographic hashes, with chain-of-custody documentation appropriate to the investigation.

• Endpoint and memory forensics: Examine disk artefacts and volatile memory using tools such as Velociraptor and Volatility to identify execution traces and persistence.
• Timeline and evidence reporting: Correlate host artefacts with security logs, distinguish findings from assumptions and document limitations for technical review. Coordinate evidence access and retention with legal or privacy teams where needed.

Cloud incident responders investigate account takeover and business email compromise, including abuse of privileged access. The work establishes which identities were used and what actions the available logs can substantiate.

• Microsoft 365 and Entra ID: Review sign-in records and mailbox audit logs for suspicious forwarding rules or unauthorized application consent.
• Cloud control-plane analysis: Examine AWS CloudTrail or Azure Activity Log records to trace unauthorized changes and identify persistence. Specialists help revoke access while preserving relevant audit evidence.

Recovery specialists support restoration after containment, checking that compromised access and identified persistence have been removed. For ransomware incidents, they review backup integrity and restoration dependencies before systems return to service; decryption or complete data recovery cannot be assumed.

For ongoing readiness, incident response consultants develop playbooks and run tabletop exercises against realistic attack scenarios. Post-incident reviews turn investigation findings into remediation tickets with explicit verification criteria. Logging gaps and evidence-retention limits become concrete changes to test before the next incident.
