Enterprise Email Archive Adhere to Strict Compliance Policies When Archiving Email

Effective business process management for enterprise messaging: Archive large email volumes on a long term basis with seamless retrieval and audit functions.

Business Continuity and Compliance for All of Your Email Communications

Companies are required to keep business critical emails for extended periods of time, protecting them from any possible manipulation. IT analysts at Gartner, a leading market research company, recommend using a managed service provider to establish a streamlined process. Retarus Email Archive stores emails securely on a long term basis and ensures that they are easily retrieved and auditable. The retained messages are protected from any manipulation or unauthorized access. Even among massive volumes, any email can be found within factions of a second (average time required to find an email in an archive containing 75 million emails: 5.1 milliseconds). Retarus supports the exporting of any archived emails, which provides business continuity in case your email system fails or messages are eliminated after deleting employee email accounts by the time they leave the company.


The complete logging of all system accesses to the email archive enables maximum control.

To ensure the highest possible level of data protection, administration access is granted exclusively on the basis of the four-eyes principle.


The unchangeability and retrievability of all archived emails means that your company meets the highest compliance requirements.
