Regency Quarantine Service
The Regency Quarantine Service (RQS) is responsible (along with the Regency Navy) for maintaining the Quarantine.
In order to maintain the Quarantine across a several parsec deep blocade zone, every system with every possible refueling point must be monitored. For this reason, the Regency Quarantine Service was created as a new auxiliary service. With the demise of the Scout Service's exploratory mission, tremendous assets, including starships, bases, and trained personnel, were made avaiable for the Quarantine mission.
However, even with the assets of the Scout Service, the task of maintaining a virus-proof seal along the entire border was a task that dwarfed the available assets. The answer was to establish the RQS Auxiliary, in which private citizens with their own ships shoulder part of the quarantine burden.
