Don't use open-source panels. Hackers will try to find security flaws within the code. It's better not to use a panel.

Definitely good advice @Golden, but control panels are very convenient and there's always room for those.  I think one can minimize the potential of security flaws in free panels by making sure one's panel is on automatic updates, and by omitting FTP and e-mail systems from the security panel. I use SFTP and external e-mail hosts instead.  I don't use bind and I don't use FTP with my free control panels as over the years I've learned with cPanel that those are the two systems hackers target the most.  I know one is still vulnerable, but if one does away with those two it is already much safer.
