We use blind software for all aspects in an enterprise environment - from email encryption/decryption through file sharing to user authentication (2-factor). The support is excellent! They are always willing to help when you have questions or need assistance after hours / weekends etc. Nothing yet but I'm sure it will be fine once they implement their own version of AWS KMS keys which would make things even better. Strongly recommend this product if your users require high security standards. File share access control & encrypting emails using 2FA via SMS messages was one area where there were problems before switching over so everything now works perfectly well without any issues at present time. Email protection against hacking attacks by malicious third parties who may try to intercept mail traffic between us & customers while travelling overseas eg business trips. This allows me great peace of mind knowing my clients' personal information remains safe throughout these journeys whilst still allowing them full ability to communicate securely during such times.
