Digital Forensics
Forensically sound preservation, acquisition, examination, analysis, validation, and reporting for digital evidence.
Find facts, preserve context, and explain the limits.
Digital forensics is not simply recovering files. It is the controlled identification, preservation, acquisition, examination, analysis, and reporting of digital information in a way that can be explained and, when needed, reproduced. TIERS Group tailors that work to the matter’s authority, evidentiary questions, deadlines, and downstream review needs.
Representative support
- Preservation and acquisition planning for computers, mobile devices, removable media, cloud-synced data, and other digital sources
- Forensic imaging, hash verification, source documentation, and chain-of-custody support
- File-system, application, browser, communication, metadata, deleted-data, and user-activity analysis
- Timeline development and correlation across multiple devices or data sources
- Assessment of opposing-party productions, exports, reports, or forensic methods
- Plain-language findings, exhibits, technical appendices, and counsel briefings
What a forensic finding can—and cannot—show
Artifacts may establish that a file existed, an application recorded an event, a device was configured a certain way, or a user account interacted with data. They do not always establish who physically held a device, why an event occurred, or whether a record is complete. Our reporting distinguishes observed artifacts, reasonable technical interpretation, material assumptions, and limitations.
Common deliverables
Preservation memorandum
Sources, risks, recommended actions, and decision points.
Forensic findings report
Methods, evidence reviewed, findings, limitations, and supporting detail.
Evidence inventory
Devices, images, hashes, exports, dates, status, and custody information.
Review package
Targeted native files, reports, tables, timelines, or platform-ready data.
Quality controls
Defensibility is built into the workflow.
Appropriate controls are selected for the evidence and use case.
Provenance
Document where evidence came from, how it was handled, and what transformations occurred.
Verification
Use hashes, logs, cross-tool checks, spot validation, and reproducible steps where appropriate.
Peer awareness
Identify high-impact findings that merit added review, testing, or corroboration.
