About this Gig
Worried your Linux server is exposed to brute-force attacks, open ports, or risky defaults?
I secure and harden servers running Ubuntu, Debian, or RHEL by working through the real attack surface not a generic checklist.
BASIC: SSH key auth, root-login lockdown, fail2ban, firewall (ufw/firewalld), unused-port review.
STANDARD: Everything in Basic, plus OS-level hardening across up to 4 public services users, sudo permissions, security updates, and service-specific firewall rules (web server, database, Docker, reverse proxy, or TLS).
PREMIUM: Full production hardening WireGuard VPN, network segmentation, admin-access separation, and application-level controls for services that must stay private.
I run this on real infrastructure I personally depend on VoIP servers, monitoring stacks, VPN-tunneled services so this isn't theory.
Every order includes a clear summary: what was checked, what changed, and how to verify it yourself.
Message me with your OS, running services, and main concern before ordering if you're unsure which package fits. I'll recommend the smallest one that actually covers your risk.

FAQ
What do you check before hardening the server?
Open ports, running services, SSH config, firewall rules, local users, sudo permissions, and internet-facing exposure — before making any changes.
Will this cause downtime?
SSH and firewall changes take minutes, and I verify new access before closing the old session. A maintenance window is recommended for service-level changes.
Which package should I choose?
Basic for SSH/firewall only. Standard if your OS and public services also need hardening. Premium if you need VPN access, segmentation, or app-level controls.
Can you secure Docker, databases, or web servers?
Yes — included in Standard or Premium depending on how many services and their complexity.
Do you provide ongoing monitoring?
Not in these packages — they secure and verify at delivery time. Monitoring is available as a separate gig if needed.
