3 of this 10 host dont work so its top 7 lol xD
If they are the TOP, then all of them are vulnerable
KnowinServers have big security holes, and all clients are vulnerable.
KnownSRV have been improved they security since my last attack, but still not secure.
And all otherz like buzzhost and this other sh**s are fully vulnerable! To make hosting dudes it's not easy, you are installing cPanel with CSF and you think it's done. Huuuuh :D
