I recently worked on securing a client's VPS running cPanel/WHM after noticing about 1,200 failed SSH login attempts over just three days. Here's what I implemented: I set up UFW rules and installed Fail2Ban, disabled direct root login for SSH, updated the kernel and verified libraries, and checked the Security Advisor in WHM to fix various warnings. After these changes, the failed login attempts dropped to fewer than 5 a day. I'm curious about what other quick and effective security measures others use for hardening a VPS in about 10 minutes. What would you recommend?

Nice work on the hardening! It's great that you tackled those basic security steps. Just a heads up, those modifications are essential not just for cPanel but also for any server setup. Whenever I set up a new server, I always start by applying those foundational security measures manually, especially if it's a non-WHM build. Keep in mind that unless you want public access, it's a good idea to limit exposure!
Absolutely! Starting with the basics is key, and it's surprising how many servers overlook these. Thanks for the reminder!
