"FTK is a court-cited digital investigations platform built for speed, stability and ease of use. It provides comprehensive processing and indexing up front, so filtering and searching is faster than with any other product. This means you can ?zero-in? on the relevant evidence quickly, dramatically increasing your analysis speed. Furthermore, because of its architecture, FTK can be setup for distributed processing and incorporate web-based case management and collaborative analysis." ?-?www.accessdata.com
Excellent Still...... This and X-Ways could cover your DF needs!
Pros: Excellent for email analysis, keyword search and live search capabilities, bundled with password breaker and registry tool, has one enterprise agent for 'on the same corporate IP range' imaging and triage, manage encryption such as PGP, FileVault and Bitlocker with ease.
Cons: Bulky 10gbs for the whole package and if you are running less than an i7/Xeon forget it, pal. Needs at least 4 SSD/PCI SSD or Raided drives such for the software, case files, SQL and TEMP to run well.
Tip: don't use the Postgres SQL use Microsoft SQL as the database tool is actually designed to run on Windows. In my experience runs smoother and more stable. Unless you want freezes, crashes and to deal with the Basil Fawlty of customer support.
