Encryption Integration Without Headaches
The need for better, stronger security has never been greater. However,
some companies have not yet implemented an encryption solution because
of concerns over cost, complexity and a noticeable performance hit to
employee’s systems.

Hardware encryption is preferable to software solutions because it provides
stronger security and has no negative impact on PCs.
stronger security and has no negative impact on PCs.
The Momentus FDE drives were the first to be introduced, and they have
been adopted by small and large businesses and government agencies
around the world. This is the only drive family to have NSA acceptance for
protecting classified, mission-critical and national security information,
making it the drive of choice for companies who want this extra measure of
confidence.

Seagate Secure
®
technology enables IT departments to manage the security
features of the drive via an enterprise security server. In fact, IT departments
can manage multi-user and admin passwords that can invoke multi-factor
logins as well as single sign-on and crypto erase functionality without ever
touching the laptop. This can be done for a handful of laptop PCs or a
worldwide enterprise. The management is all done via independent software
vendors who have designed security management software to integrate with
the Seagate Secure technology.
