The trio admitted charges of unlawful employment and misleading immigration officers, the Associated Press said.
They are Nick Cryne, 30, of Manchester, Niall Young, 34, from Cheltenham, and Ben Hope, 27, from Birmingham.
The men were working undercover for a private intelligence firm and had no terrorist links, their company said.
Intelligere, a firm offering corporate investigation services, said they were trailing two executives alleged to have swapped company secrets when they were arrested in Mombasa last week.
The group formed a three-man team tasked with tracking the pair, Intelligere explained.
The three Britons were each fined £220.35 (35,000 Kenyan Shillings) after entering guilty pleas to a Kenyan magistrate on Monday, the Associated Press said.
Gary Lincoln-Hope, chief executive of Intelligere, said the firm spent the weekend in contact with the British Embassy in Kenya and the Foreign and Commonwealth Office.
Mr Lincoln-Hope said: “Their activities conducted prior to being arrested and put in jail were wholly legal. They are not linked to terrorism.”
Intelligere, a division of the XFOR Group, handles international corporate intelligence operations.
Referring to the issue, a Foreign Office spokesman said: “We are aware that a number of British nationals were arrested in Mombasa, Kenya, on September 22.
“We are providing consular assistance to them.”
