What is FortiWeb?
Fortinet's web application & API firewall (WAF) — protecting apps and APIs from OWASP attacks, bots and app-DDoS.
ML-based, Fabric-integrated.
Unprotected estate vs modern security — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | Unprotected / signature email | FortiWeb (Fortinet) |
|---|---|---|
| App-layer attacks | Firewall passes them | WAF blocks them |
| Detection | Signatures only | ML anomaly detection |
| False positives | Painful, permissive-only | Low — run in blocking |
| Zero-days | No signature, missed | Anomalous, caught |
| APIs | Under-protected | API security |
| Bots | Get through | Good/bad/human sorted |
| Deployment | Fixed | Appliance/virtual/cloud/SaaS |
| The estate | App-security silo | Security Fabric |
A network firewall can't stop app-layer attacks — SQL injection, XSS, API abuse pass through as web traffic. ML-based WAAP, low false positives, native to the Fabric.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
ML Anomaly Detection
Builds a model of normal traffic to your application and detects anomalies — catching zero-day and sophisticated attacks while cutting the false positives of signature-only WAFs.
OWASP Top 10 Defence
Protects against SQL injection, cross-site scripting (XSS), and the rest of the OWASP Top 10 — the core web application attack classes.
API Security
Protects the APIs that power modern apps and are increasingly targeted — schema validation, abuse detection, and API-specific threats.
Bot Mitigation
Advanced bot mitigation — distinguishing good bots (search engines), bad bots (scrapers, credential-stuffers, attackers) and real humans, blocking the bad ones.
Security Fabric
Powered by FortiGuard intelligence and part of the Security Fabric — sharing threat intelligence with the rest of your Fortinet security.
Network, endpoint and cloud telemetry converge in one fabric; threats are joined up once, not pursued tool to tool.
Twelve capabilities. Detect, protect, Fabric.
FortiWeb protects apps and APIs from the attacks a network firewall can’t stop — ML-based WAAP, part of the Fortinet portfolio.
Machine-Learning Detection
Models normal application traffic and flags anomalies, catching zero-day and evasive attacks with far fewer false positives.
Fewer False Positives
The ML approach dramatically reduces the false positives that plague signature-only WAFs — making FortiWeb far less painful to operate and tune.
Zero-Day Protection
Because it detects anomalies from normal behaviour rather than known signatures, FortiWeb catches novel, never-before-seen attacks against your apps.
OWASP Top 10 Defence
Protects against SQL injection, XSS, and the full OWASP Top 10 — the core, most dangerous web application attack classes.
API Security
Protects REST and GraphQL APIs with schema validation and abuse and anomaly detection, for the APIs modern apps depend on.
Bot Mitigation
Advanced bot management — distinguishing good bots, bad bots (scrapers, credential-stuffers) and humans, and blocking malicious automated traffic.
Application-Layer DDoS
Protects against application-layer (Layer 7) DDoS attacks — the sophisticated, low-and-slow attacks that overwhelm apps and that network defences miss.
Credential Stuffing Defence
Detects and blocks credential-stuffing and account-takeover attempts — the automated login abuse that targets web apps.
SSL/TLS Inspection & Offload
Inspects encrypted traffic for threats and can offload SSL/TLS — protecting apps without blind spots and improving performance.
FortiGuard Intelligence
Powered by FortiGuard Labs threat intelligence — the same intelligence across the Fabric — so web defence reflects threats seen everywhere.
Security Fabric
Part of the Fortinet Security Fabric — sharing web/API threat intelligence with FortiGate and the rest of your Fortinet security.
Flexible Deployment
Available as physical/virtual appliance, in the cloud, or as SaaS (FortiWeb Cloud) — protecting apps wherever they run.

Here’s what genuinely sets Fortinet FortiWeb apart.
Web apps and APIs need protection a network firewall can't give
Web apps and APIs must be reachable, and SQL injection, cross-site scripting, API abuse, bots and application-layer DDoS ride inside permitted HTTPS traffic, so a network firewall passes them. FortiWeb inspects application-layer content in front of your apps and APIs and blocks these attacks, complementing FortiGate.
Machine learning: fewer false positives, and it catches the unknown
Signature-based WAFs flag legitimate traffic, so many run in permissive mode, and they miss novel attacks. FortiWeb’s machine learning models normal traffic for your application and flags anomalies, catching zero-day and obfuscated attacks with far fewer false positives, so you can run it in blocking mode with confidence.
Full web app AND API protection (WAAP) — including bots
Beyond the OWASP Top 10, FortiWeb protects REST and GraphQL APIs, separates good bots, bad bots and humans to stop scraping and credential stuffing, and defends against low-and-slow application-layer DDoS that network defences miss. One product covers the app, its APIs, bots and DDoS, leaving fewer gaps.
Part of the Security Fabric — and FortiGuard-powered
FortiGuard Labs feeds FortiWeb global intelligence on web and API attacks, malicious sources and botnets. As a Security Fabric member, it shares intelligence both ways with FortiGate and other components, so a source attacking your applications can be blocked network-wide, and multi-layer attacks are seen as a whole.
Flexible deployment — protect apps wherever they run
FortiWeb runs as a physical appliance, a virtual appliance, a cloud-native deployment in AWS, Azure or Google Cloud, or FortiWeb Cloud, a managed WAF-as-a-service with no infrastructure. The same machine-learning protection applies across on-prem, cloud and hybrid apps, so application security isn’t fragmented.
The honest scope
FortiWeb offers machine-learning detection with few false positives, full WAAP coverage of apps, APIs, bots and DDoS, and Fabric integration. Cloudflare, Akamai and the native WAF in AWS or Azure appeal for CDN-integrated edge protection; Imperva and F5 compete. FortiWeb suits teams wanting a WAF they can run in blocking mode.

Quick poll — what’s driving your evaluation?
Talk to an advisor“ML detection let us finally run our WAF in blocking mode without drowning in false positives; our old one was permissive-only.”
“It caught a zero-day injection attack with no signature, flagged as abnormal for our app. A signature WAF would have missed it.”
“Our app is API-driven and attackers target the APIs directly. FortiWeb protects our REST and GraphQL endpoints, not just the front end.”
“Bot mitigation stopped the credential-stuffing and scraping that was hammering our site — it tells good bots, bad bots and humans apart accurately.”
“FortiWeb Cloud let us protect our apps with WAF-as-a-service — no appliance to manage, just point traffic through it. Fast to deploy.”
“FortiWeb shares intelligence with our FortiGate via the Fabric, so a source attacking our apps is blocked network-wide.”
“Application-layer DDoS protection handled a Layer 7 attack that our network DDoS defences didn't see — the low-and-slow app-targeted kind.”
“Deployed as a virtual appliance in our cloud alongside the apps — consistent protection across on-prem and cloud, one WAF approach.”

FortiWeb vs the WAF / WAAP field
Edge/CDN WAFs, specialists and cloud-native WAFs — honest lanes; the edge is ML-based low-false-positive detection with full WAAP, native to the Fabric.
| Dimension | FortiWeb | Cloudflare / Akamai | Imperva / F5 | Cloud-native WAF | No WAF |
|---|---|---|---|---|---|
| Approach | ML WAAP + Fabric-integrated | Edge/CDN WAF | WAF specialists | Basic native WAF | The gap |
| ML detection / low false positives | ML-based, low FP | Rules + some ML | Signatures + ML | Rules-based | None |
| API + bot + app-DDoS (WAAP) | Full WAAP | Strong | Strong | Basic | None |
| Platform integration | Native Security Fabric | Own platform | Own platform | Cloud ecosystem | None |
| Best fit | Effective, operable ML WAF; full WAAP; Fabric-integrated; flexible deployment | Edge/CDN-integrated WAF at scale | WAF specialists | Basic, cloud-native needs | Nobody — apps need a WAF |
Which approach fits you?
Honest fit signals — because the fastest way to lose your trust is to pretend one product wins every scenario.
Choose FortiWeb if…

- You're a Fortinet estate wanting Fabric-integrated app security
Cloudflare / Akamai if…
- You want an edge/CDN-integrated WAF delivered at global scale
Imperva / F5 if…
