CSI Linux

Free

The homepage presents the virtual appliance and the bootable image as downloads, and it does not print a dollar price for the operating system. No paid CSI Linux tier was on the page opened 20 Oct 2026. The academy section lists certification names, including CSIL-CI and CSIL-COA, and does not print a course price in the block this review read. Do not invent a tuition. The 2026.4 string is a filename in two download URLs, not a price. MD5 71cc3f48981bd60a7879123bf6abcde9 is a checksum beside the VirtualBox link, not a license key. If a training page later prints a fee, quote that page.

The homepage calls CSI Linux a digital forensic and OSINT operating system, and the body says it is an open-source operating system for digital forensics, incident response, and OSINT. The downloads section says that when CSI_TorVPN is turned on it encapsulates all traffic through Tor, similar to Tails, and that CSI_Gateway points to a Whonix gateway VM. The bootable version, that paragraph says, has only CSI_TorVPN. The virtual appliance sentence says the appliance is available in three formats, VirtualBox and VMware. That is the page's own wording. The VirtualBox control's URL ends in the filename CSI Linux 2026.4 VirtualBox.7z, with MD5 71cc3f48981bd60a7879123bf6abcde9 printed beside it. The VMware control's URL ends in CSI Linux CMS 2026.4 VMware.7z. Those filenames are the version string this listing can quote. No Ubuntu, Debian, or Kali base was named on the page.

• 2026.4 is a filename. The VirtualBox URL contained CSI Linux 2026.4 VirtualBox.7z. The VMware URL contained CSI Linux CMS 2026.4 VMware.7z. The visible headings did not print a version.
• No base distro. The homepage did not name Ubuntu, Debian, or Kali. The account it did print is csi / csi.
• Tor and a Whonix gateway. The page says CSI_TorVPN sends traffic through Tor, similar to Tails, and CSI_Gateway points at a Whonix gateway VM.

1. 1

   Cite 2026.4 as the download filename, and say the page did not print a separate version line.

2. 2

   Change csi / csi before the appliance is shared. Do not repeat the SIEM account.

3. 3

   Read the Tor and gateway sentences as the vendor's description, not as anonymity for a case.

• A version banner is about to be invented. The downloads section did not print a version or a base distribution. The VirtualBox link's filename was CSI Linux 2026.4 VirtualBox.7z, with MD5 71cc3f48981bd60a7879123bf6abcde9. The VMware filename was CSI Linux CMS 2026.4 VMware.7z. Cite the filename. The page's appliance sentence says three formats and then names VirtualBox and VMware.
• The appliance is about to be shared as csi / csi. That pair is what the downloads section prints. Change it. A SIEM download on the same page uses a different account, which this listing does not repeat. Minimums printed beside the appliance were 6+ GB of RAM, 140+ GB of disk, and 2+ cores.
• CSI_TorVPN is about to be briefed as anonymity for a case. The page says it encapsulates traffic through Tor, similar to Tails, and that CSI_Gateway points at a Whonix gateway VM. Those are the vendor's descriptions of two options. They do not authorize collection, and they do not name a base distro the page omitted.
