Firewall1

Firewall1 is a network security platform designed to monitor and control traffic entering and leaving an enterprise network. It functions as a boundary firewall and can enforce policies at multiple layers, including network and application layers. The platform supports rule definitions based on IP addresses, ports, protocols, user identities, and application signatures. It can be deployed as a hardware appliance, a virtual appliance, or a cloud-native service, and it includes a policy engine, a data plane, and a management console. Policy rules typically implement a default-deny posture with explicit allow rules.

Key features include stateful packet inspection, deep packet inspection, intrusion prevention, VPN support (IPsec and TLS), NAT, URL filtering, and application-aware controls. It provides centralized logging, role-based access control, and integration with security information and event management systems. The platform offers APIs for automation (REST and CLI) and supports high-availability configurations and multi-site deployments.

Performance and scalability: Firewall1 can be deployed in small offices, datacenters, or as cloud-based services. It supports clustering, load balancing, and horizontal scaling to meet demand while maintaining predictable latency. The architecture separates control and data planes to improve reliability and facilitate management, auditing, and version upgrades.

History and usage: Firewall1 originated as a software-based project in the early 2010s and was subsequently commercialized by a security vendor. It has been used in a variety of sectors, including enterprise networks, public institutions, and service providers, as part of defense-in-depth strategies.
