Now they didn't have the Americans on side, were things more dangerous for Cabrillo and his crew?

It is because they don't have an easy source of intel or support if necessary. They have to do all the research/background/infiltration/extractions without access to the CIA's information network

I think the lack of access to intel would make it harder for them.

I'm not convinced that they're at too much of a disadvantage - they have state-of-the-art communications and technology at their disposal anyway; I doubt they'd get much more from Overholt.
The only problem I could foresee would be if the Americans didn't know what Juan was up to and there was a resulting mistaken identity scenario - eg, the drone taking out a 'terrorist target' that turned out to be 'friendlies'.

Where they are going to be at a disadvantage is having the info on the inside of the different government agencies and that back up. They do have some very high tech equipment so that will work in their favor. They also may not receive assignments from the government like they were so the higher powers may soon realize that they need Juan and his crew more than Juan needs them.

I think they were in more danger, but mainly from the Americans. Their technology and contacts helped them significantly on their missions but wouldn't know what the Americans were up to. This makes it very dangerous as was shown.

I thought they were in more danger too especially with the drone.
