BlackBerry scored a number of deals with the U.S. government even as it makes the transition from a primarily smartphone maker to software.

The company signed a five-year, multimillion-dollar deal to run emergency notifications for the U.S. Senate, and also received approval for its phone management system and latest phone model to be used by the Department of Defense and its crisis communication software to power the Sergeant at Arms’ Joint Emergency Mass Notification Systems (JEMNS) for five years.

In addition, Blackberry said that AtHoc, a crisis communications firm it bought last year, had expanded a deal with the U.S. Coast Guard to cover staff in Washington, D.C.

“As the leading provider of crisis communication software to the U.S. Departments of Defense and Homeland Security, AtHoc has demonstrated the ability to enable highly secure information-exchange for the world’s most demanding organizations, said John Chen, Executive Chairman and CEO of BlackBerry.

“The U.S. Senate is joining more than three million US federal government personnel today in using BlackBerry’s AtHoc software for their crisis communications capability,” he added.

The U.S. Federal government remains BlackBerry’s biggest customer, despite the advent of strong competition from Android devices. Agencies have signed long-term handset contracts with BlackBerry sometimes for more than three years.

These deals have failed to impress investors and critics who say the company is taking too long to deliver meaningful outcomes, even as the company delves into corporate and government IT.
