• Enterprise-grade security tailored for small and home offices

  The Firebox T25-W brings enterprise-grade, multi-layered protection to compact environments. It goes beyond basic firewall rules by incorporating advanced threat prevention, intrusion prevention, and malware protection that work together to identify and block evolving attacks. With reputation-based threat intelligence, real-time updates, and policy-driven controls, you can enforce a robust security posture without needing a dedicated security operations team. This makes it especially suitable for small businesses, startups, remote teams, and home offices that need professional-grade defense with simplified management and predictable costs.

  Security policies are designed for everyday business use, including controlled access for remote workers, secure guest networks, and safe integration of IoT or BYOD devices. The T25-W supports centralized security services that help enforce consistent protections across users and devices, minimizing the attack surface without complicating daily operations. IT teams benefit from streamlined policy creation, clear visibility, and policy inheritance that scales as the organization grows.

• High-performance throughput for modern workloads

  With up to 3.14 Gbps firewall throughput, the T25-W is built to handle modern business workloads without bottlenecks. This level of performance supports secure access to SaaS applications, cloud services, video conferencing, and other bandwidth-intensive tasks when users are distributed across multiple sites or remote locations. The appliance maintains consistent performance under load, ensuring that security features do not impede productivity. This makes it ideal for small offices adopting digital workstreams, data-centric applications, and VPN-based remote work policies where speed and reliability are non-negotiable.

  Beyond raw throughput, the T25-W optimizes traffic through intelligent security tooling, enabling smoother experiences for employees and customers alike. This balance of speed and protection helps organizations meet rising security expectations while preserving low latency for critical business applications.

• Flexible networking with five 1 Gb ports and clear segmentation

  The T25-W provides five 1 Gb Ethernet ports to support diverse network topologies without requiring aggressive hardware expansion. This port count enables logical segmentation of WAN, LAN, and management networks, as well as practical deployment of separate paths for guest access, trusted devices, and critical servers. With straightforward VLAN support and policy-based control, you can isolate traffic, enforce quality of service for voice and video, and protect sensitive data flows. The compact form factor and minimal cabling make it an attractive option for offices with limited space or for deployments where quick provisioning matters.

  Administrators can design secure, scalable layouts that fit current needs while preserving room to grow. The 5-port configuration is particularly well suited for small sites with dedicated uplinks to cloud services, dedicated management networks, or a straightforward path to cloud-based security services, all while maintaining a tidy, easy-to-manage network footprint.

• Comprehensive VPN capabilities for site-to-site and remote access

  Designed to connect dispersed locations and remote users securely, the Firebox T25-W supports up to 10 Branch Office VPNs. This count facilitates reliable, encrypted connections between multiple office sites or home offices, enabling centralized authentication, consolidated policy enforcement, and consistent security across the network. Remote workers can securely access corporate resources through the same secure tunnels that protect site traffic, reducing the risk of data exposure when employees work from home, in transit, or at customer sites.

  With VPN support integrated into the firewall’s security fabric, administrators can deploy scalable access for contractors, partners, or field staff. The result is a flexible, cost-effective approach to remote connectivity that aligns with modern hybrid work models, ensuring that security travels with the user—whether they’re in the office or on the move.

• Optional integrated Wi‑Fi 6 wireless module for seamless coverage

  The Firebox T25-W offers an optional integrated Wi‑Fi 6 wireless module, enabling enterprise-grade wireless coverage without needing a separate third-party access point. This feature brings improved efficiency, faster speeds, and better support for densely populated environments. Wi‑Fi 6 enhances performance for multiple devices simultaneously and reduces latency for critical applications, which is particularly valuable in small offices with BYOD devices, guest access needs, or IoT ecosystems. Centralized management of wireless and wired networks from a single security appliance simplifies configuration, monitoring, and policy enforcement, helping you maintain a cohesive security posture across both wired and wireless domains.

  Security stays at the forefront even with wireless access. The integrated module supports robust authentication, encryption, and policy-based access control to ensure that wireless clients adhere to your corporate security rules. This makes the T25-W a compelling, all-in-one solution for environments that require reliable wireless connectivity alongside enterprise-grade firewall protection.
