Exactly. If he's allowed to be free, but banned from leaving the country, FVEY SIGINT can throw their entire bag of tricks against his comms while working remotely. Maybe they can recover keys, infrastructure details, etc. Dude is going to need to build his own SCIF, surrounded by proximity detectors and armed guards, offgrid power generation, fed by quantum-resistant encrypted fiber lines with splice detection alarms in a hurry. Nothing but disdain for FVEY, but this is a solid approach on their part.
