Three services, one team
Post incident review, digital forensics, and expert witness services are delivered by the same team — so the practitioners who contained your incident are the same ones who reconstruct the timeline, document the chain of custody, and testify if it comes to that.
Service 01
Root cause analysis, containment validation, and timeline reconstruction after a security incident. Convergent identifies how the attacker entered, how they moved, what they accessed, and what stopped them — or didn’t. The review produces a lessons-learned report and a concrete remediation plan so the same entry point isn’t used again.
Service 02
Disk imaging, memory analysis, network traffic review, and artefact collection following confirmed or suspected compromise. All evidence is handled under a rigorous chain of custody — admissible in legal proceedings. Convergent’s forensics practitioners hold industry certifications and have worked alongside law enforcement and legal counsel in regulated industry contexts.
Service 03
Court-ready forensic reports, testimony preparation, and litigation support for in-house counsel and outside law firms. Convergent’s practitioners can be engaged as expert witnesses in civil and regulatory proceedings, and provide technical support to legal teams throughout discovery and dispute resolution.
Two ways to engage

Talk to us now →For law firms and legal counsel
Convergent works alongside law firms and in-house legal counsel before, during, and after security incidents — providing the technical expertise that counsel needs without stepping outside the engagement boundaries that protect privilege.
Privilege-aware engagement
Convergent can be engaged through outside counsel to preserve attorney-client privilege over forensic findings and incident review documentation, where applicable.
Chain of custody documentation
All forensic evidence is collected and documented under protocols that maintain admissibility. Your legal team receives evidence packages they can rely on in regulatory proceedings or litigation.
Breach notification support
Convergent provides the technical findings — scope of access, data affected, timeline of compromise — that legal counsel needs to assess notification obligations under HIPAA, GLBA, state breach laws, and SEC disclosure rules.
Expert witness testimony
Convergent’s practitioners are available as qualified expert witnesses in civil and regulatory proceedings. Reports are written to be understood by a non-technical judge or jury — without losing technical precision.
Common questions
A retainer covers proactive readiness: documented playbooks, quarterly tabletop exercises, annual programme review, and priority access during an incident. Active engagements are scoped to the specific incident — containment, forensics, recovery, or post-incident review, depending on what’s needed. Retainer clients receive preferential pricing and guaranteed response SLAs.
Retainer clients have a guaranteed response time agreed at engagement. For non-retainer active incidents, Convergent aims for initial contact within hours of being reached — not days. The earlier we’re involved, the more options are available. Evidence preservation degrades quickly in the first hours of an incident.
Yes, routinely. Convergent is experienced working as a technical partner to law firms and in-house counsel during incident response and litigation. We understand the engagement structure that preserves privilege, provide findings in formats counsel can work with, and are available to explain technical findings to non-technical audiences including regulators, boards, and courts.
Convergent can be retained as an expert witness in civil or regulatory proceedings involving a cybersecurity incident. This typically involves reviewing forensic evidence, preparing a written expert report, and providing testimony. We can also provide consulting support to counsel during discovery — reviewing opposing expert reports and identifying technical weaknesses in the other side’s narrative.
Get started
A retainer costs a fraction of an active incident engagement — and means your team has a tested response plan, practiced escalation paths, and a known partner before anything goes wrong.
