CRU USB 3.1 WriteBlocker 3-Port Read-Only Access

Protect data integrity during forensic review, incident response, and evidence handling with controlled read-only access. The CRU USB 3.1 WriteBlocker is designed for workflows where even a single unintended write can compromise chain of custody. It allows investigators to connect up to three USB 3.1, 3.0, or 2.0 storage devices while preventing write operations at the hardware level. That matters when teams need to examine removable media quickly without altering timestamps, file structures, or device contents. By enforcing read-only access, the write blocker helps reduce risk during triage, imaging preparation, and evidence review. USB 3.1 support keeps the device relevant for modern storage media while maintaining compatibility with older USB generations commonly encountered in the field. For labs, security teams, and legal discovery environments, the value is control. Instead of relying on software-only safeguards, this hardware approach adds a physical layer of protection around sensitive workflows. It is a practical choice when the cost of a mistake is far higher than the cost of the tool itself.
