Security Intelligence Far East (SIFE) was a British intelligence organization created in 1946 as the Far Eastern regional headquarters of the Security Service, MI5. It was based in British-controlled Singapore and established by Colonel Cyril Egerton Dixon, a career MI5 officer with a great deal of war time counter intelligence experience in Britain and India.[1][2][3][4] SIFE (like SIME) was also a MI5 controlled organisation, which partially merged its counterintelligence section with the regional headquarters of MI6 in 1950.[5][6] SIFE controlled a number of MI5 Defence Security Officers (from 1949, named Security Liaison Officers) in Singapore, Kuala Lumpur, Malaya and across the Far East.[7][8]
SIFE was headquartered in Phoenix Park, Singapore which was also where the headquarters of British Commission-General for Southeast Asia Malcolm MacDonald’s headquarters were located.[9]
