The Jovian Diplomacy Service, or JDS, were PROBE's American "cousins", distinct from Control's branch of the CIA.

Michael worked for them. On 1 June 2019, Michael sent Giles a package containing Varunastra to get it away from Control. (WC: Varunastra)

Late 2019, Brittany Mordley was sent to the UK to visit PROBE. She met Maxie Masters in the airport when she arrived and encountered a zombie-like alien called Death 4. (PROSE: Nowhere Women ^[+]Error: Code 2 - no data stored in variables, cache or SMW.)

Giles later contacted "the other organisations", including the J.D.S., when Maxie Masters fell prey to an unidentified, potentially deadly alien sickness, hoping one of them would have some medication in storage that was suitable for her Gendar biology. In the end, however, whatever help the J.D.S. could have provided did not have to come into play as Maxie was cured the very same night. (HOMEVID: The Only Cure)
