Linux Server Security
Layered hardening for Linux hosting servers: firewall, brute-force defense, malware scanning, IDS, and continuous auditing.
Linux servers face automated attacks within minutes of going online. Our security service layers firewall management, brute-force protection, antivirus and rootkit scanning, intrusion detection, and quarterly audits over a hardened baseline, closing the gaps that default installations leave open.

What's included
CSF firewall design with default-deny inbound and egress filtering; fail2ban and cPHulk brute-force protection across SSH, FTP, mail, and panel logins; nightly antivirus/malware scans with quarantine and alerting; OSSEC/Wazuh intrusion detection with human-reviewed alerts; file-integrity monitoring on system paths; quarterly configuration audits with graded findings.
Response when it matters
On detection of compromise: immediate isolation, forensic imaging, entry-vector analysis, clean rebuild, verified data restore, full credential rotation, and a written post-incident report, then hardening so the same vector never works twice.
Frequently asked questions
Can you secure an already-running server?
Yes, we baseline, harden, and verify live systems without reinstalling, then keep them hardened continuously.
Do you replace our hosting provider's security?
We complement it: provider network controls plus our OS-level hardening, monitoring, and response.
