Clavister NetShield is a family of high-capacity Next-Generation Firewalls (NGFW) designed and developed in Sweden, targeting datacenter protection and secure remote networking. The product is available in multiple hardware form factors — from small desktop units to large datacenter appliances — as well as virtualized versions for public and private cloud environments. It can also be deployed as a container, running directly in Kubernetes or Docker for cloud-native and microservice environments. Key functional areas include: - **Routing:** Supports BGP for intelligent path selection, BFD for fast link failure detection, multiple virtual routers, and dynamic routing protocols for interoperability with existing network equipment. - **High Availability:** Millisecond-level failover to secondary devices with extensive health checks covering links, routes, gateways, and third-party hosts. - **VPN:** Supports thousands of simultaneous VPN tunnels with hardware-accelerated encryption and IPsec-based site-to-site connectivity. - **Deep Application Awareness:** Identifies and inspects over 4,500 applications and protocols, enabling granular policy enforcement and logging. - **Security Analytics:** Provides a single-pane-of-glass console with real-time insights, vulnerability prioritization, and risk recommendations. - **Traffic Management:** Offers bandwidth optimization and intelligent traffic prioritization. - **Central Management:** Managed via Clavister InControl, which is included in all licensing plans and provides zero-touch deployment, shared policy sets, scheduled firmware updates, role-based access, and revision control. Licensing is offered in tiered plans (Essentials, Enhanced, Premium).
