The Purrtec Encryption Key is a hardware solution that encrypts digital files with one click. Unlocking the files requires a physical key and password, so you are assured that hackers can’t access or read your files and data. Purrtec protects your data with government-grade AES 256- BIT hardware encryption, which means whether you’re encrypting a WitSec list, a deposition, or your family’s online banking data, it’s kept under a heavy lock and key, and no data is housed externally. Expect full data privacy because even the Savvi staff can’t access your data. Lastly, this encryption key is astonishingly simple, just connect Purrtec to your computer, select the files you want to encrypt, drag and drop them into the Purrtec window, type your password, and you’re done. The exact same process works for decryption.
