As the thread Seb provided talks about- there are a couple of different options. VACL's would definitely work but to your question about PVLAN's, they're really not that complicated once you understand how they work. Here's a good guide about them: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3560/software/release/12-2_52_se/configuration/guide/3560scg/swpvlan.html
There won't be just one best solution. Every environment is different and has different requirements. I would recommend you read through the link that I posted above and also do a bit more research on things like VACL's. It's your responsibility working on the network to come up with the solution that best fits for your environment. Find a couple of good reasons to go with one option over the other and then develop out a plan and implement it. Any of the options available could end up being the "best" one.
