Digital Forensics & Incident Response
When a breach hits, the first 72 hours decide your liability.
Our DFIR team deploys rapidly to establish the timeline, scope the full impact, preserve court-admissible evidence, and deliver the documented facts your counsel and regulators require.
How it works
- PreserveAcquire disk & memory, hash every artifact, lock chain of custody.
- ReconstructRebuild the attacker timeline across endpoint, network and cloud.
- ScopeRoot cause, blast radius, and what data actually moved.
- ReportCourt-admissible evidence plus a board-level translation.
A breach is not just a technical event, it is a legal, regulatory and reputational one. What you can prove in the first three days shapes your notification obligations, your insurance position and your defensibility. NexarisTech's incident response practice combines disk and memory forensics, malware reverse engineering and disciplined evidence handling so the facts are established once, correctly, and preserved for anyone who later asks.
We work alongside your internal team and legal counsel, not around them. Every action is logged, every artifact is hashed, and every conclusion is written in language your board and regulators can act on.
Full acquisition and analysis of endpoints, servers and volatile memory to reconstruct attacker activity.
Static and dynamic analysis to determine capability, persistence and data-handling behaviour.
Timeline reconstruction across SIEM, endpoint, network and cloud logs.
The initial access vector, the blast radius, and what closes it for good.
Chain-of-custody handling and court-admissible documentation for litigation and regulators.
A worked example, the raw signal on the left, the board-level translation on the right.
The attacker got in through one phishing email. Nothing left the building.
We can prove the entry point, the three machines touched, and that no data was exfiltrated, with a preserved, court-admissible evidence trail for your legal team and regulators.
What you receive
- Forensic timeline & root-cause report (board + technical versions)
- Court-admissible evidence package with chain of custody
- Indicators of compromise and containment guidance
- Regulatory-notification support pack
Every engagement is owned by a dedicated lead and advisor, backed by a CISSP / CISM / GCIH-certified team. You get one line to the people doing the work, not a ticket queue.
Start a conversationHow fast can you deploy on an active incident?
We mobilise remotely within hours and can operate 24/7 through containment. For urgent incidents, email security@nexaristech.com or select 'active incident' in the assessment form.
Is your evidence admissible in court?
Yes. We follow ISO 27037 / NIST 800-86 acquisition and chain-of-custody practices so artifacts hold up in litigation and regulatory proceedings.
Do you work with our existing IT and legal teams?
Always. DFIR is a collaboration, we integrate with your responders and counsel, and every report is written to be understood by both technical and legal audiences.
Can you help with regulatory notification timelines?
We provide the documented facts and impact scoping you need to meet HIPAA and sector notification windows, and support your counsel through the process.
