Do those Spies Successful abilities within target city remain even after he has been removed, I.E. do they continue to lose that production?

[@gamerbaum1487]

can every fraction spy?

[@Carrot_Carl]

Hi! What can I do against infiltration?

[@WaervynsWorld]

Build improvements that improve security, counterespionage, and roundups (although those cost some happiness)

[@phylippezimmermannpaquin2062]

Theres also a perk in the common tree your heroes can learn to boost security

[@thewhitefox3097]

Maybe I don't stand how it works or I did not understand when you said it but how do you increase your security?

[@WaervynsWorld]

Very sorry for the late reply. Your hero can affect it, you can build improvements that affect security, you can do counterespionage as well as doing roundups :)
