Tyto Athene acquires StackArmor to boost cyber compliance, cloud capabilities

Tyto Athene, a Reston-based technology solutions company that works with defense, intelligence and civilian agencies, has completed its acquisition of StackArmor, a McLean cloud and security automation solutions company, according to a Thursday announcement.

A request for details about financial terms of the deal was not immediately returned Monday.

“The acquisition of StackArmor represents a significant milestone in Tyto’s growth strategy,” Dennis Kelly, Tyto Athene’s CEO, said in a statement.  “StackArmor’s innovative cyber, compliance and cloud automation solutions will immediately enhance our ability to support critical missions across defense, national security and public safety sectors.”

Tyto Athene was founded in August 2018 when Arlington Capital Partners, a Washington, D.C.-area private investment firm that specializes in government-regulated industries, acquired the government solutions division of Black Box.

Founded in 2016, StackArmor will provide Tyto Athene with cloud strategy, migration and cloud-managed services for regulated industries in compliance with federal cybersecurity frameworks aimed at protecting government data. Additionally, StackArmor brings to the table cyber automation and continuous monitoring solutions, according to a news release.

In 2024, Tyto Athene acquired MindPoint Group, a McLean-based cybersecurity solutions company, and Microtel, a Maryland-based software development and systems engineering firm that works with NASA and international space programs.

Tyto Athene has 11 offices in the United States and Europe. In April, the company announced it had been awarded an indefinite delivery, indefinite quantity contract with a ceiling of $378.7 million to provide lifecycle support for the U.S. Army’s simulation, training and instrumentation programs.
