I want to install a old OSX on a old mac, but i m wondering : is it secure to use it ?
for example Snow Leopard ?

Well, clearly, internet security depends on the kind of internet browsing you do. Sticking to major sites will likely not cause any problem with even modest security measures.What follows is my opinion only, and I realize that it "goes against the grain".
If you need to install Snow Leopard because it has something in it that you like or need (to run older software, for example), just do it and don't worry about it.
Just a week ago I retired a 2010 MacBook Pro that came with Snow Leopard. I continued to use it as the "regular OS" on that machine for it's entire service life of almost 7 years.
Ran great, never a problem.
"Security" was never an issue for me.
Again, my opinion only.

You're exaggerating the risk. There are few to no malware programs out there for any OS X version, and while Apple may no longer be patching holes in Snow Leopard it has a less than one percent market share now so there is no incentive to use any known exploits. The calculation may be different if you are doing something that would be a high value target where a hacker would expect to get their money back for the time it takes to get in.If you visit sites that display ads or load any sort of third party tracking javascript, you are at extreme risk for eventual infection. Same goes if you check email. Installing and maintaining a local HOSTS file like https://github.com/StevenBlack/hosts will help, by preventing your machine from ever loading content to many known bad sites.
And never, ever install Flash or Java.
Good advice for the latest MacOS, not just older ones.And never, ever install Flash or Java.

PowerPC Leopard, despite being even older and still vulnerable, is less likely to be exploited due to all the effort this would take
