Current PoW chains, yes. Some other consensus schemes have higher threshold requirements to pull off a similar sort of attack, in particular you can look at Casper FFG and other byzantine fault tolerant PoS schemes.
There are some with lower threshold tolerance of these attacks based on the idea that they're unlikely and the added threshold doesn't actually add security. I don't know about that but some people seem to think so.
