Protection Detail

The Protection Detail was the division of the Federation Security Agency responsible for guarding the safety of the President of the United Federation of Planets. 

The Protection Detail communicated with the Federation Starfleet using a cipher code known as "November-brave-seven-nine-white."

In 2381, the lead agent in the Protection Detail's personal guard for Federation President Nanietta Bacco of Cestus III was former Starfleet officer Steven Wexler. 

In 2384, the Protection Detail suffered devastating losses as a result of the Breen Intelligence Directorate's use of remotely-piloted Soong-type androids to attack President Bacco and Gorn Imperator Sozzerozs at a secret summit being held at the Bank of Orion. Numerous agents, including Wexler, were killed when the Breen androids penetrated the bank's defenses to fake an assassination attempt on Bacco and Sozzerozs. 

Prior to 2381, presidential protection was the duty of Starfleet Security.
