SEPA direct debit (and the earlier non-SEPA versions) allow the bank to do just that: show a list of charges, set monthly limits and cancel the authorization.

Unfortunately, most foreign companies don't offer SEPA, but my bank also offers virtual CCs that are tied to a single biller, so not only I can revoke them at any time, they are also useless if leaked.

Regular CCs are a pain in comparison.
