CODi's 4GB 256-Bit Encrypted USB Flash Drives are a convenient mobile solution that protects personal or company data with unique I-Shield security. Performance is maximized because encryption occurs on the drive's internal chip set rather than external software. Device lockdown occurs after 6 invalid attempts to prevent brute force attacks. The end user is required to run the software upon connection to his or her PC, which means all files transferred to this drive thereafter will be encrypted immediately.
