Linux Server Hardening Check – Configuration and Exposure Review

The free hardening tools produce a wall of output. This produces a report you can act on and hand to someone else.

The Linux Server Hardening Check reviews the configuration of a Linux server you own — a VPS, a cloud instance, an office box — against the settings that decide whether a routine internet scan finds a way in. It is the only product in the QuickScan line that runs on Linux rather than Windows.

What it checks

• SSH configuration: root login, password authentication, key handling and exposure to the open internet
• Every service listening on a network port, and whether it needs to be
• Firewall rules and whether they match what is actually running
• User accounts, sudo privileges and accounts that can log in but should not
• Available security updates and how far behind the system has drifted
• File permissions on sensitive paths, world-writable files and unexpected SUID binaries
• Logging and audit configuration — whether you would have any record after an incident

What you get

• A written PDF report emailed back to you, typically within one business day.
• Every finding rated Critical / High / Medium / Low, with the exposure explained rather than just flagged.
• Exact configuration changes to make, with the file and directive named.
• An executive summary that a non-technical owner can read.
• Reporting built to CompTIA Security+ and PenTest+ practice standards.

Who it's for

Anyone running a Linux server they set up once and have not revisited — a website host, an application server, a home lab that ended up doing real work.

Requirements

• A Linux server you own or administer (this product does not run on Windows)
• Root or sudo access
• An internet connection
• About 10 minutes

What this is not

QuickScan is detection and advisory only. It reads configuration; it never changes a setting, never installs anything permanent, never exploits a weakness. Because it is Linux-only it cannot be included in the Windows QuickScan bundles and is sold on its own. It is not a certification, an audit or an attestation.
