Certified Illinois digital forensic analysts performing device imaging, artifact level examination, and detailed reporting for law firms, corporations, and courts statewide.
Behind every Illinois digital forensic report is an analyst who actually touched the evidence. The analyst is the person who plugged in the write blocker, verified the hash, ran the extraction, parsed the databases, carved the deleted photos, and built the timeline. If the analyst level work is sloppy, no amount of downstream expert polish saves it. Our Illinois analysts follow written SOPs, work in a controlled lab environment, and cross review each other’s findings before anything leaves the shop. That is how we deliver work product that survives Frye challenges in Illinois courts.
On a typical Illinois engagement, our analyst first performs an intake inspection the physical condition of the device, the presence of tamper indicators, the serial number, and the state (powered on, off, locked, encrypted). Photographs are taken and logged. The analyst then places the device into a Faraday shielded environment where needed and connects it to a validated acquisition workstation. For computers, that means a write blocker (Tableau T35u for SATA, T356s for SAS, hardware bridges for M.2); for phones, it means the correct Cellebrite cable and firmware combination for the exact device model. Hashes are computed at acquisition and re verified before any examination touches the image. During examination, the analyst runs both a full tool decode (AXIOM, Cellebrite, Oxygen) and hand parses raw databases (SQLite journals, plists, LevelDB) to catch what automated tools miss. Timeline building uses plaso or Magnet AXIOM Timeline Explorer. Findings that will appear in a report are traced back to an artifact ID, a file path, and a source module no free floating conclusions.
Our Illinois digital forensic practice is organized around six recurring engagement types. Each one is a defined scope of work with clear deliverables, flat fee pricing, and a documented chain of custody. Most Illinois matters we handle combine two or three of these, sequenced to match the litigation or incident timeline.

Our Illinois examiners work with the same court vetted toolchain used by federal agencies: Magnet AXIOM, Cellebrite Inseyets and Physical Analyzer, Oxygen Forensic Detective, X Ways Forensics, EnCase, FTK, Autopsy, Volatility for memory, Wireshark for network captures, and Griffeye for image analytics. Every case is documented, hashed at ingest, and cross validated across at least two tools where the finding materially affects the outcome. This tool discipline is what allows Illinois expert reports to withstand cross examination in state and federal court.
A digital forensic analyst is the person who actually performs the imaging, parsing, and artifact level examination. In Illinois engagements, analyst level work is where the case is won or lost an incomplete extraction, a missed database, or an unverified hash can undo months of legal strategy. Our analysts follow written SOPs modeled on SWGDE and NIST guidance, work in a controlled lab, and cross review each other’s findings before anything leaves our custody.
Illinois courts evaluate digital forensic evidence under the Frye general acceptance standard (Donaldson v. Central Illinois Public Service Co., 199 Ill. 2d 63 (2002) (reaffirming Frye general acceptance standard) as applied through Ill. R. Evid. 702, 703, and 705) as applied through Ill. R. Evid. 702, 703, and 705. Our reports and testimony are prepared to satisfy that standard in every District Court across Illinois’s 102 counties and in the Northern, Central, and Southern Districts of Illinois. We also handle 720 ILCS 5/17 51 (computer tampering) (breach of computer security), § 632 (recording of confidential communications), Business and Professions Code violations, family law discovery under 750 ILCS 5 (Illinois Marriage and Dissolution of Marriage Act), and civil discovery obligations under Ill. S. Ct. R. 201 219 (discovery) Chain of custody is documented per NIST SP 800 86 guidance and Illinois case law requirements for authentication of electronically stored information.
Illinois is the fifth largest state economy in the United States in the world on a standalone basis, and that footprint shapes the digital forensic work we see: Downtown Chicago and West Loop tech corridor IP theft and trade secret matters; manufacturing, healthcare, and logistics sector fraud, IP, and contract disputes in Chicago; Northwestern Medicine, Rush, and University of Chicago Medicine healthcare and biotech breach investigations in Chicago; logistics, trucking, and agricultural fraud across Central Illinois and Downstate; and cross border criminal defense matters throughout the Collar Counties (DuPage, Lake, Will, Kane, McHenry) and Downstate Illinois. Every industry brings its own artifact set GitHub commits, cloud IDE logs, DAW project files, medical device telemetry, EDI trade documents and we build the exam plan around what actually matters to the case.
CFCE (IACIS), EnCE (OpenText), GCFE and GCFA (SANS/GIAC), Cellebrite CCO and 815 ILCS 530 (Personal Information Protection Act) and the Illinois Personal Information Protection Act (815 ILCS 530) and the Biometric Information Privacy Act (740 ILCS 14), Magnet Forensics MCFE, and BlackBag Blackthorn. Individual analyst CVs available on request.
