Security Overview

Security isn’t a single setting you flip on once. It’s a process that touches every layer of your stack, from account passwords to network firewalls and SSL/TLS. Our security articles cover four main pillars of security:

Account & Access – lock down logins with strong passwords, two-factor auth, and secure notes.
Network Protection – shield ports with Cloud Firewall rules and VPN tunnels before traffic even hits your server.
Server Hardening & Monitoring – minimize attack surface (services, permissions, file-system tweaks) and run scheduled vulnerability scans.
Encryption & Certificates – keep data in transit private with correctly installed, auto-renewing SSL certificates.
