Tata Communications, a leading provider of a new world of communications, today announced it has been positioned by industry analyst firm Gartner, Inc. in the Challengers quadrant of its “Magic Quadrant for Managed Security Service Providers (MSSPs) in North America” report.(1) The Magic Quadrant evaluates MSSPs such as Tata Communications on completeness of vision and ability to execute, and uses selection criteria based on service and product capabilities and other factors.

“In just one year, we have launched and scaled our managed security services business, and are now focused on meeting the highest expectations that our customers have from us, and validating our customers’ choice of Tata Communications as their choice for managed security services for their sites in developed and emerging markets worldwide,” said John Landau, senior vice president of Global Managed Services for Tata Communications. “We believe that our placement in the Gartner Magic Quadrant for Managed Security Services reflects the trust that our customers have placed in Tata Communications and its ability to deliver world-class security services.”
