• Protect your existing Gmail, iCloud, or any public email content
• Protect your existing MS Exchange account content
• Trustera’s email clients secure your content natively on your iPhone/iPad, and Mac

Trustera Security protects your email, using ultra secure PGP encryption in a simple, easy to use format. Trustera’s email services work harmoniously with your existing email service or provider. Your emails are protected regardless of where they are stored (on local servers, or in the cloud), or whatever networks they may traverse. Because Trustera uses asymmetric encryption, your emails can only be read by the intended recipient – and not by local administrators, hackers, or anyone other than who you designate. Trustera encrypts/decrypts your email locally on your system so your content is never stored (even temporarily) on our servers. Using our services is easy because we manage all the underlying keys for you. All you need to know is your passcode.

Who can you share secure content with? Anyone. Because encryption and signing is free, all you need to do is send a potential recipient an invitation to create a Trustera account, and you and that person can share emails that are completely secure.

Trustera Security makes hacking obsolete.
What makes Trustera’s solution unique is in the unlikely event you get hacked, it simply won’t matter. Hackers may get your emails but there is nothing they can do with the encrypted data. Additionally, there is no concern that in the unlikely event Trustera’s servers are compromised – our servers don’t contain any of your content. We also make your emails (when using Trustera Security) HIPPAA, CFPB, ITAR, FERPA, and CJIS compliant.

• Encryption is local, so your emails are protected when at rest, and when in flight
• Full protection for attachments, pictures, or any content that you may want to include
• Easy key management brings military grade encryption for any user
• Trustera's encryption uses industry standard PGP (RFC 4880) and is compatible with many other encryption products (Symantec's PGP, and GPG for example)
• Trustera's services for encryption and signing are free, for anyone, anywhere, anytime

All the features you expect, making email management simple and secure.

Better than expected

This app not only does what it should, it does so seamlessly across every platform imaginable. Easy to use, and industry standard (read compatible with other encryption products) makes this really stand out. I use the email client all the time, but you don't have to - there is a nice workflow that lets you use your native email app and send encrypted messages to Trustera when they are received. You still need to use the app to send encrypted messages. Love that it works on my iPhone and Mac. Good work guys.

This is a fantastic email app that supports pgp encryption. But using trustera's keys is useless since you can't export them so it's only useful when communicating with other trustera users. You have to import your own pgp keys on their website then mark it as default. Only supports pgp/mime format and you have to store your private keys on their servers as well.
