Server Security
Hardening, firewall and performance optimization for your Linux and Windows servers.
Software Firewall
Port Management
We narrow the attack surface with L3/L4 level stateful packet inspection (SPI) supported software firewall configurations specific to the operating system architecture (Linux/Windows). By keeping only the necessary ports open with the principle of service isolation, we prevent unauthorized access attempts at the network layer.
Linux Servers
cPanel · Ubuntu · CentOS · AlmaLinux · Debian
- CSF / iptables / firewalld installation
- Closing unnecessary ports
- CSF integration for cPanel/WHM
- Ubuntu, CentOS, AlmaLinux, Debian support
- SSH port restriction and login audit
- Login Failure Daemon (LFD) configuration
Windows Servers
Windows Server 2016 · 2019 · 2022
- Windows Firewall advanced rule set
- Closing unnecessary ports
- RDP port restriction and IP whitelist
- IIS security settings
- Service and role-based access control
- EventLog monitoring configuration
Server Hardening
We make the server fully protected against internal and external threats by optimizing kernel hardening, file system permissions, and user authorization hierarchy (RBAC) at the OS level. We provide defense in depth (Defense in Depth) by eliminating vulnerabilities arising from default configurations.
Kernel & PHP Security
- Kernel-based symlink protection settings
- PHP.ini security adjustments
- Vulnerability audit for PHP versions
- PHP build optimization tailored to needs
- Exec-Symlink, Perl, CGI execution control
Web Server Security
- Mod_security installation and rule editing
- Mod_userdir access restriction
- Open_basedir configuration
- Rate-limiting mod_security for WordPress brute force
- Prevention of cross-account file access
Access & Isolation
- Prevention of root directory traversal
- Restriction of cross-account transitions
- Chroot control in system and user directories
- Prohibition of MySQL remote access
- Changing and restricting SSH port
Licensed Security Solutions
- CloudLinux installation and configuration
- User isolation with CageFS
- KernelCare live kernel patching
- LVE resource limit settings

- InnoDB buffer pool configuration
- Slow query log analysis
- Index optimization
- Connection pool settings
Web Server Optimization
- Apache / Nginx configuration fine-tuning
- Worker and thread count optimization
- Keep-alive and timeout settings
- Gzip/Brotli compression activation
- PHP-FPM pool optimization
LiteSpeed Optimization
- LiteSpeed Web Server fine-tuning
- LSCache configuration
- QUIC / HTTP3 activation
