Totemo is the only secure email gateway offering a module enabling the encryption of confidential email messages inside of company networks without the additional burden of any client-side software or plug-ins.

The Internal Encryption module can be used as an optional add-on to the TrustMail Gateway or as a standalone solution. It makes it possible to protect emails all the way from sender to recipient without any client-side installation.

TrustMail Internal Encryption is revolutionary because it solves the well-known weakness of the traditional secure email gateway concept where emails are only encrypted between the gateway and the external recipient. The confidential messages still travel unprotected – as fully readable plain text - inside of the company network until they reach the gateway.
Until now, this issue could only be addressed with end-to-end encryption, which implies either the use of additional software client components, proprietary email protocols or encrypted transmission channels. In any case, the company completely loses control over its email traffic.

TrustMail Internal Encryption solves these issues; nevertheless, it maintains all the advantages of a server-based approach like central definition of security policies, the automated management of keys and certificates, etc. The public keys of the internal users are used to encrypt messages sent inside of the company, so that it is not needed to redirect the internal email traffic to go through TrustMail.

The advantages delivered by TrustMail Internal Encryption are significant:

• Enables functional (shared) mailboxes
• Fully supports delegation rules
• Allows content security, virus checking, etc. before the messages enter or leave the corporate network assuring the company maintains much desired control over its email traffic
• Neither plug-ins nor additional software are required
• Fully automated generation and management of personal certificates

TrustMail Internal Encryption can be swiftly installed and seamlessly integrates into any existing mail environment. It can be run as a stand-alone product as well as in combination with the TrustMail Enterprise Edition.
