What is FTK?

FTKForensic Toolkit (FTK) is a commercial digital-forensics suite developed by AccessData and now owned by Exterro, used to acquire, index and analyse computer evidence.


FTK (Forensic Toolkit) is a long-established commercial digital forensics platform first released by AccessData in the early 2000s. After AccessData's acquisition by Exterro in 2020, the product is marketed as Exterro FTK and is widely used by law-enforcement, government and corporate examiners. The suite includes FTK (analysis), FTK Imager (free evidence acquisition tool that creates verified E01/AFF4/raw images and supports live previews), and FTK Lab/Enterprise for remote and large-scale investigations. Key capabilities include distributed indexing for fast keyword search across terabytes, deduplication, registry and email analysis, mobile-device support, and exportable reports. FTK is often compared with EnCase as the two flagship commercial DFIR tools.
