Firewall, IDS, and Threat Protection
We deploy and manage complete network security stacks using OPNSense, Suricata, CrowdSec, and ClamAV. Our zero-trust approach helps you detect, block, and respond to threats before they reach your data.
From perimeter firewalls and VPNs to enterprise-grade mail filtering with Proxmox Mail Gateway (PMG), we protect your organization from phishing, malware, and spam before it reaches the inbox. PMG integrates seamlessly with Mailcow, Exchange, or cloud services while offering full reporting, quarantine, and DKIM/SPF alignment.
- OPNSense firewall with IPS/IDS (Suricata)
- Threat intel feeds + CrowdSec collaborative defense
- Secure VPN access (IPsec, WireGuard)
- Email filtering with Proxmox Mail Gateway (PMG), including DKIM, SPF, RBLs, ClamAV, and spam scoring
- Fail2Ban + UFW/iptables for SSH and web ports
We harden your infrastructure layer by layer — from mail to firewall — using hardened, audit-ready practices and tools.
The Benefits
Whether you're securing one office or multiple sites, we deliver advanced network protection that works quietly in the background.
- Transparent, scalable firewall configuration
- Full visibility into all traffic and events
- Automated IP reputation blocking
- Email protection without Microsoft dependency
Security shouldn't be expensive or closed. We deliver open protection without compromise.
Capabilities
Firewall & Perimeter
We build and manage firewalls using OPNSense or pfSense, including multi-WAN setups, VLANs, and UTM rulesets.
Monitoring & Response
We monitor ports, traffic, mail gateways, and logs in real time. You’ll get alerts, reports, and remediation if needed.
Where This Setup Works Best
This model fits offices, clinics, salons, and online operations handling sensitive client data and requiring practical protection for both network and email flows.
- Branch offices connected through VPN with centralized firewall control
- Organizations exposed to high phishing and spam volume
- Teams that need audit trails for network and security events
Sample Configuration (Security Stack)
Perimeter & Access
- OPNSense HA pair with multi-WAN and VLAN segmentation
- WireGuard/IPsec tunnels for branch and remote users
- Suricata IDS/IPS rules with automatic block actions
Email & Response
- Proxmox Mail Gateway with DKIM/SPF/DMARC checks
- CrowdSec + Fail2Ban for dynamic attack blocking
- Centralized logs and alerting for operations teams
You get unified protection from gateway to inbox, with clear policies, full visibility, and faster incident response.
