FortiWeb 400F is built to protect the application layer where traditional network firewalls stop short. It helps inspect HTTP and HTTPS traffic, enforce policy at the web tier, and reduce exposure to attacks aimed at forms, sessions, and APIs. For teams responsible for customer portals, transactional sites, or partner-facing services, that distinction matters. This SKU pairs the appliance with 1 year of FortiCare Premium and FortiWeb Standard, giving infrastructure teams a defined support and subscription window from the start. That simplifies budgeting and shortens the time between purchase and deployment. It also makes the platform easier to standardize when the goal is to secure a specific application estate rather than refresh an entire perimeter stack. FortiWeb 400F is a practical fit when you need dedicated WAF controls in a compact hardware footprint. It is well suited to organizations that want stronger application protection than a basic firewall can provide, while keeping the deployment model straightforward for operations and procurement.
