Tata Communications Offers Managed Two-Factor Authentication as a Cloud-based Service

Service Makes Strong Authentication More Accessible and Affordable; Helps Businesses Protect Information Assets Without the Cost of Deploying New Infrastructure

MUMBAI, India, January 21 - Tata Communications, a leading provider of a new world of communications,
today announced the launch of its managed two-factor authentication service
that adds to its portfolio of Managed Security Services (MSS). The new
service helps all enterprises to further secure their networks and comply
with security-specific certifications and regulations.

According to the Open Security Foundation(1), 436 security and
database breaches compromising more than 218 million records have been
reported in 2009. Tata Communications' managed authentication service helps
address this by providing a globally consistent solution that helps
organizations secure access to internal networks and infrastructure and
prevents unauthorized access within and outside an organization.

"Enterprises around the globe are leveraging mobile devices
and laptops on an increasing basis, raising the risk of a security breach,"
said John Landau, Senior Vice President of Global Managed Services for Tata
Communications. "While two-factor authentication offers far more protection
for enterprises than passwords, many enterprises have delayed the adoption
because of the complexity of deployment, staffing requirements and
infrastructure cost. Our hosted managed authentication service addresses
these challenges for customers and reduces the cost of ownership for
safeguarding the enterprise against unauthorized access."

The new service from Tata Communications is hosted and
authenticates users before they are granted access to their organization's
applications, data, services, and network devices. Users enter a personal
identification number (PIN) and a six digit one-time passcode displayed on a
token. Depending on their security policies and end users' preferences,
customers can choose to use software or hardware tokens. Software tokens
provide increased convenience as users no longer need to carry a separate
device. Instead, they can leverage everyday mobile devices that they already
own and carry such as smart phones and PDAs, or their own desktop.

Tata Communications has teamed up with the global leader in
two-factor authentication, RSA–The Security Division of EMC (NYSE: EMC)–to
help power the managed two-factor authentication solution. "RSA SecurID is
the world's most widely deployed and trusted strong authentication solution
with more than 20 years of outstanding performance and innovation," said Tom
Corn, Vice President of Product Marketing for RSA, The Security Division of
EMC. "By offering RSA SecurID through a managed authentication service, Tata
Communications will help its enterprise customers bring confidence to
everyday transactions by providing secure internal and remote access for
employees, customers and partners.

With managed authentication, firms will be able to eliminate
the learning curve associated with new technologies while saving on
operational costs. Managed authentication incorporates best practices
regarding secure authentication design, implementation, and change management
of security systems to protect critical business assets. With a wholly
managed authentication solution, no upfront investment is required to install
and deploy infrastructure and servers. Tata Communications also handles all
the details and time-consuming tasks related to token life-cycle management.
In addition, staffing, administrative and logistics overhead, user
management, and personnel requirements are greatly reduced, lowering total
cost of ownership (TCO).

"Our software token technology and managed authentication
service offer a compelling price advantage for mass deployment through mobile
devices that can enable service providers and enterprises to quickly
establish and maintain large-scale, trusted infrastructures," said Landau.
"With more managed and secure end points, the volume of B2B and B2C
communications will increase and this will help improve operational
efficiency and streamline e-business transactions."
