Bossert's resignation is in the latest high-level departure from the White House after the replacement of the secretary of state last month.
Before joining the Trump White House, Mr Bossert worked as deputy homeland security adviser to President George W Bush - a position that was created after the terror attacks of September 11th, 2001.
Under Bossert, the administration also focused on developing plans to combat botnets-armies of zombie computers that nations, criminals and vandals use to force their adversaries offline.
Bossert's exit follows a White House announcement that National Security Council spokesperson Michael Anton would also be leaving.
Bossert, meanwhile, offered no indication he knew his time at the White House was coming to an end.
Bossert has publicly taken issue with assertions that the Trump administration has not imposed sufficient costs on Russian Federation.
Bossert's voice was well heard in the cyber security sectors.
He becomes one of the dozens of senior officials in the Trump administration to resign since the president's 2017 inauguration. Bolton served as US permanent representative to the United Nations from 2005 to 2006, and as undersecretary of state for arms control and global security from 2001 to 2005.
Bossert is said to have been an ally of Bolton's predecessor H R McMaster and had faced an uncertain future in the new dispensation.
Bossert appeared to share the president's views on policy, and he helped spearhead the administration's response to last year's hurricanes in Texas, Florida and Puerto Rico.
