The inquiry by the Republican-run House Intelligence Committee also said there was no intelligence failure and no delay in sending a CIA rescue team.
The Obama administration had been accused of mishandling its response.
Four Americans, including Ambassador Christopher Stevens, died in the raid carried out by Islamist militants.
In a report released on November 21, the committee dismissed a claim that the CIA had not provided adequate security for its own agents near the Benghazi consulate and that the Obama administration had failed to send support.
It said it reached its conclusion based on “thousands of hours of detailed investigation” and interviews with senior American officials and the agents who had been on the ground during the attack on September 11, 2012.
“The CIA ensured sufficient security for CIA activities in Benghazi and, without a requirement to do so, ably and bravely assisted the state department on the night of the attacks,” the report said.
“Appropriate US personnel made reasonable tactical decisions that night, and the committee found no evidence that there was a stand-down order or a denial of available air support.
“The CIA received all military support that was available.”
However, the Benghazi report concluded that the mission had inadequate security and therefore had required CIA assistance.
