Dimension	Azure Web Application Firewall	Fortinet FortiWeb
Pricing and trial	Azure WAF with Application Gateway v2 Amount unverified — check official pricing Azure WAF with Application Gateway for Containers Amount unverified — check official pricing The two exact core offers are usage-metered Azure services, but their current numeric regional rates were not exposed in the public pricing state and are therefore omitted. Azure Front Door is a broader delivery-service route: Standard supports custom WAF rules, while Premium includes full WAF capabilities and managed rule sets. Its verified North America USD route meters are retained only in purchasePaths. Agreement, region, traffic, logging, and connected-service charges can change the total cost. Azure Front Door Standard or Premium: Azure Front Door is a broader content-delivery and global application-delivery service. Standard provides custom WAF rules without an extra WAF fee; Premium includes managed WAF rule sets, bot protection, threat intelligence, security analytics, and Private Link. The retained offers are Front Door route charges, not standalone Azure WAF prices. Full profile	Standard Bundle Requires quote · custom quote Advanced Bundle Requires quote · custom quote Enterprise Bundle Requires quote · custom quote Standard includes the core web security, IP reputation, antimalware, and support set. Advanced adds Cloud Sandbox, Credential Stuffing Defense, and Threat Analytics. Enterprise adds Advanced Bot Protection, Client-Side Security, and DLP. FortiAI and SOCaaS are additional services. Public numeric appliance and bundle prices are not published in the current ordering guide. FortiWeb hardware appliance bundle: CAPEX route for a FortiWeb 100F through 4000F appliance sized by throughput and paired with a Standard, Advanced, or Enterprise bundle. FortiWeb-VM S-series subscription: Yearly FortiWeb-VM subscription route for private cloud or IaaS, sized from 1 through 16 vCPUs and available with the three current bundles. FortiWeb-VM perpetual license: Permanent-use FortiWeb-VM license route. Fortinet recommends the S-series subscription in the current ordering guide but continues to document perpetual VM availability. Public-cloud marketplace deployment: FortiWeb-VM deployment through supported public clouds using BYOL or PAYG. Marketplace usage prices and infrastructure charges vary by provider and instance type. FortiWeb container appliance: Containerized FortiWeb-VMC route for Docker environments, with models sized from 25 Mbps through 3 Gbps in the current data sheet. FortiAppSec Cloud SaaS: Separate SaaS platform that incorporates the former FortiWeb Cloud WAF and related cloud services. Its Standard, Advanced, and Enterprise plans are not FortiWeb appliance or VM editions. Full profile

Key features	Regional dedicated WAF through Application Gateway v2 Kubernetes ingress WAF through Application Gateway for Containers Global edge WAF through Azure Front Door Standard custom rules or Premium managed protection Azure-managed Default Rule Set and supported Core Rule Set versions Anomaly scoring, detection mode, prevention mode, custom rules, exclusions, and rule overrides	Dual-layer machine-learning detection for known attacks, anomalies, and zero-day threats.

FortiView dashboards, real-time logs, attack analytics, REST API, Syslog, SNMP, and email monitoring. Hardware, VM, container, and public-cloud deployment with active-passive or active-active appliance clustering where supported.
Cons	Exact Application Gateway WAF v2 and Containers WAF numeric rates were not exposed in the public pricing state Total cost depends on deployment resources, capacity, requests, data transfer, regions, logs, and connected Azure services Front Door Premium is a broader service purchase, not a standalone WAF license	Numeric edition, appliance, support, renewal, and implementation prices are not public in the current ordering guide. The current ordering guide and one FortiWeb 8.0 licensing topic disagree about whether DLP, Advanced Bot Protection, and SOCaaS belong to Advanced, Enterprise, or add-on packaging the final quote must resolve entitlement scope.
Category buying score	78	81Higher category-fit score
Rank	#4	#1
Context	Security & Privacy / Web Application Firewall (WAF) Software	Security & Privacy / Web Application Firewall (WAF) Software
Protection efficacy	80Delivers foundational defense via managed rulesets, anomaly scoring, and custom rules, but requires continuous operational review to maintain performance without false positives.	86Machine-learning detection, bot mitigation controls, virtual patching through scanner integration, and FortiGate or FortiSandbox threat sharing combine into a broad protection stack for self-managed web and API fronts when the matching services are entitled.
Policy accuracy and tuning	76The presence of managed rules, custom rules, exclusions, and version-specific features supports accurate policy expression, but the need for testing and false-positive tuning on managed rules limits the score.	81Uses machine learning to analyze anomalies and automate threat detection, reducing reliance on manual policy tuning, though fine-tuning capacity remains bound to the limits of the selected hardware or VM model.
Application and API coverage	81Protects up to 40 websites per gateway instance and supports regional, Kubernetes, and edge routes, but lacks comprehensive api auto-discovery or schema governance.	87The product targets web applications and APIs together, with API discovery, OpenAPI, XML, and JSON schema controls, and positive-security policy, so coverage fits mixed app and API estates under one self-managed WAF deployment.
Security operations	79Facilitates security workflows with Sentinel and infrastructure-as-code tools, but lacks Security Copilot support on container-based gateways and requires separate services for multi-policy management.	81Facilitates security operations through integrations with FortiGate and FortiSandbox to enable central threat sharing, virtual patching, and optional managed SOCaaS.
Performance and reliability	80The platform has route options with autoscaling, zone redundancy, and global edge delivery, which supports reliability planning; the score is moderated because the facts do not provide measured reliability results or service guarantees across all routes.	76Deployment options across hardware, VM, container, and public cloud support flexible reliability planning, but VM sizing is license-bound by vCPU and the current facts do not establish uniform throughput or fault-tolerance outcomes across all deployments.
Deployment and integrations	84Azure WAF integrates with Azure-native deployment patterns, including Application Gateway, Kubernetes Gateway API resources, Azure Monitor, Event Hubs, Sentinel workflows, and Defender for Cloud, which makes it fit well for Azure-centric environments.	87Hardware, VM, container, and public-cloud deployment plus FortiGate, FortiSandbox, and third-party scanner integrations make the product fit mixed infrastructure and Fortinet-centered environments, with the main boundary being that integration breadth does not prove continuous synchronization quality.
Support and total cost	62The product is usage-metered, can accumulate extra charges from transfer, logs, and connected services, and does not publish exact current numeric rates in the supplied facts, which makes cost planning materially less predictable.	60Standard includes support, but pricing is quote-based, public numeric prices are not published, the trial is limited, and several services are edition- or add-on-dependent, so buyers need a quote to judge total cost and support scope.
