OPNsense & Zenarmor: Our Open-Source Firewall Specialisation
Secure. Optimize. Simplify.
OPNsense is not just a product we sell. It’s the firewall platform we know inside and out. We’ve deployed OPNsense in environments ranging from small offices to multi-site enterprises with complex routing requirements. We customise OPNsense builds to match specific client needs, contribute to the ecosystem, and pair it with Zenarmor for next-generation application-layer security.
Why We Specialise in OPNsense
OPNsense gives us the flexibility to build exactly the firewall solution a client needs, without the constraints of proprietary vendor licensing. We can customise rulesets, build plugins, integrate with monitoring stacks, and tune performance at a level that commercial firewalls simply don’t allow. As a Premium Zenarmor Partner, we combine this with enterprise-grade application visibility and threat protection.
What We Build with OPNsense
Multi-WAN & Failover
Load balancing across multiple ISPs with automatic failover. 5G, fibre, and MPLS links managed as a unified WAN.
High Availability Clustering
Active-passive and active-active clustering for environments where downtime is not an option.
VPN Architecture
Site-to-site and remote access VPN using WireGuard, OpenVPN, or IPsec. We design VPN topologies for multi-site organisations with dozens of locations.
Policy-Based Routing
Granular traffic steering based on source, destination, application, or time of day.
Multi-Site Management
OPNcentral for centralised policy and configuration management across distributed deployments.
Zenarmor: Application-Layer Security
Zenarmor transforms OPNsense into a Next-Generation Firewall with AI-based web filtering, application control, deep packet inspection, intrusion detection and prevention, and rich analytics. We handle deployment, policy design, and ongoing tuning so your network has full visibility into what’s actually happening at the application layer.
