No enterprise theater — just the checklists that actually work.
Every playbook is a sequence you can follow top to bottom — not a reference dump. Buy once, keep it forever, free updates for life.

7 steps to secure an exposed server, fast.
Updated October 2026
I run these checklists on real servers before they go in a playbook. If a step doesn't work exactly as written, it doesn't ship. When I find a bug in my own work, I fix the playbook and you get the update free.
Most guides are reference dumps — technically correct, useless at 2am. Mine are sequences: do step one, then step two. Order is what separates a ten-minute job from a ten-hour outage.
No forty-page intro on why security matters. No scare tactics to upsell you. Just what to type, what to check, and how to know it worked.
I run Linux servers and WordPress sites for small businesses. I write the checklists I wish I'd had — practical steps that actually work.
SkyPress is my publishing imprint: every playbook is something I use in real work, written down in the order I'd want to follow it. If a command is in there, it's because I typed it and watched it work.
