Exterro FTK Imager vs OSForensics

Exterro FTK Imager is a forensic imaging and preview tool for acquiring and preserving digital evidence. It creates full disk images in multiple industry-standard formats and verifies them with MD5 or SHA-1 hashes. Investigators can preview files and folders before acquisition, capture volatile RAM and registry data from a live device, and read or write common forensic image formats. Files can be exported for further analysis in FTK Forensic Toolkit. Supported acquisition sources include Windows and Linux hard drives, CDs and DVDs, thumb drives and other USB devices. The tool runs on Windows only, though it can image a Linux device; it does not collect directly from phones or other mobile devices. The free FTK Imager plan is listed at free. FTK Imager Pro costs $499 a year and adds encryption-aware workflows, iOS advanced logical collection, faster preview and targeted acquisition. Exterro identifies incident response and DFIR teams, law enforcement, forensic examiners, and corporate security and HR investigators as intended users.

OSForensics is digital investigation software for extracting and examining forensic data from computers. It searches and indexes files, looks inside documents and email archives, and attempts to recover deleted files. Hashing can verify evidence or compare it with known files, while extension checks can flag files whose extensions are incorrect. The software can surface recent activity such as opened documents, web history, connected USB devices, and network shares. Password tools target commonly used web browsers and can use rainbow tables to retrieve passwords from hashes. Investigators can group evidence into case files, cryptographically hash data, and export reports readable as HTML or PDF, with narratives and external reports. It can maintain a secure audit trail and create or restore disk images for analysis. OSForensics can also run from a portable USB drive. Listed evidence sources include Windows, Mac, Linux, Android, and iOS/macOS file systems, plus disk images, memory dumps, email, browser data, registry hives, SQLite, and ESE databases. Windows 7, 8, 10, and 11 are listed, as are several Windows Server versions. A free license and a 30-day trial are listed; subscription pricing is $95 per user per month.
