We set up Linux and Windows Server, virtualisation and monitoring. We check networks for vulnerabilities and restore them after attacks.
We set up servers so they run reliably, get updated on time and report problems before users notice them. We also handle security, from closing unnecessary ports to recovering after an attack.
Servers and virtualisation
- VPS/VDS on Ubuntu, Debian, CentOS: basic hardening and SSH key login
- Control panels: FASTPANEL, ISPmanager, aaPanel
- Nginx and Apache web servers, Let’s Encrypt SSL certificates
- Windows Server: Active Directory domain controller, DNS, DHCP, group policies
- Proxmox VE and VMware ESXi hypervisors
Monitoring
We deploy Zabbix or Prometheus with Grafana and set up triggers and alerts, including in Telegram. You see link load, disk health and equipment availability on one screen.
Security
- Corporate VPN on WireGuard, OpenVPN or IPsec
- L7 filtering and web application firewall (WAF)
- Perimeter audit: open ports, equipment vulnerabilities, weak configurations
- Recovery after a breach or DDoS: traffic cleaning, closing vulnerabilities, restoring from backups
