In its open letter to "valued customers, partners and fans" the mobile device maker said "You can continue to count on BlackBerry."
The company emphasized that it is debt free with substantial cash on hand and is restructuring with a goal of cutting expenses by 50%.
"Governments all over the world, global corporations and businesses that simply cannot compromise on security choose and trust BlackBerry," the company said in the letter signed by The BlackBerry team. "Security is our heritage, and the industry recognizes that BlackBerry is the most secure when it comes to the device, server and, of course, our global data network. Have no doubt that you can continue to trust us to keep your communication safe and private."
BlackBerry reported a staggering loss of almost $1 billion last month for its second quarter earnings and also said it planned to slash its workforce by 40% or about 4,500 jobs. It also has a tentative deal to sell the company to its biggest investor, Fairfax Financial Holdings, for $4.7 billion.
The handset maker also said last month that it planned to refocus on its core enterprise customer base.
