Entrust's PKI Adopted by Italian Certification Authority, IBM Subsidiary Intesa

Deal marks first Italian trust center leaving incumbent PKI provider for new security vendor

DALLAS, December 6, 2010 - The result of a major technology displacement, the Entrust, Inc., public
key infrastructure technology (PKI) is now available to the Italian market as
a cost-effective hosted service. Intesa, a trusted certification authority
(CA) and subsidiary of IBM, has switched from the incumbent PKI provider to
offer new and existing customers Entrust Managed Services PKI products and
capabilities.

"Intesa is continually seeking methods for improving service and
technology for its customers," said Intesa CEO Ugo Di Pietro. "This
opportunity enables us to provide a proven, cost-effective hosted PKI
platform that is ready to grow with evolving technology, the security
requirements of our business and, ultimately, the needs of our customers.
That versatility was key in our decision to switch hosted PKI platforms."

Entrust's agreement with Intesa displaces the incumbent PKI provider.
Intesa now offers new customers Entrust hosted PKI solutions but also helps
existing customers migrate to the managed service. One of the key
differentiators for the market, Entrust is invested in providing better
service and more advanced technology like elliptic curve cryptography.

"Entrust's world-leading PKI capabilities enable strong IT vendors like
Intesa to offer security solutions to customers who demand the best -
especially as technology quickly evolves," said Entrust President and CEO
Bill Conner. "Couple our best-in-class PKI capabilities with unparallel
service and it's a compelling formula for customers."

The Entrust PKI, whether deployed on customer premises or as a
software-as-a-service, allows organizations to establish and maintain a
trustworthy environment by providing certificates that secure many
off-the-shelf applications using encryption, digital signatures and strong
authentication. This PKI platform helps control access to resources, prevent
theft of information and comply with privacy and digital signature
regulations.

Modular and fully integrated, the Entrust Authority PKI is built on the
foundation of trust and audit for issuing and managing users' digital
identities. A PKI establishes and maintains a trustworthy networking
environment by providing key and certificate management services that enable
authentication, encryption and digital signature capabilities across
applications - all in a manner that is transparent and easy to use.

Headquartered in Turin, Italy, Intesa has been an accredited CA since
March 2001. Intesa supplies digital signature and logic security services
through its PKI. Since 1987, Intesa has been trading as a leading provider of
qualified services/solutions. The company has more than 8,000 companies using
its comprehensive portfolio of IT services.
