Great, enterprise-grade encrypted e-mail is not a small thing to accomplish. In nearly every case, you're looking at special hardware, software and management to keep everyone's private email... well, private. AppRiver is hoping to get around that by offering its own over-the-top secure encrypted email solution with an app its just released called CipherPost Pro.
Instead of running your own back-end security system, the idea of CipherPost Pro is that you can use any email provider you'd like, and simply pay a subscription fee to use this app's encryption system. Features you'd expect like mail tracking, data loss protection and MDM (Mobile Device Management) integration are all on board. CipherPost Pro is compliant with industry security standard such as HIPAA, PSQIA, PCI DSS, Sarbanes-Oxley and more.
You can take a look at CipherPost Pro in the Play Store at the link above.
