Dimension	Fastly Next-Gen WAF	Fortinet FortiWeb
Pricing and trial	Essential Requires quote · custom quote Professional Requires quote · custom quote Premier Requires quote · custom quote All three exact-product platforms require a quote. Essential is the baseline platform, Professional adds custom signals and templated rules, and Premier adds advanced rate limiting. Fastly also publishes two broader Security package families that include Next-Gen WAF alongside package-specific capacity, support, services, or adjacent products; those bundles are purchase paths rather than WAF plans. Fastly Security Core, Core Plus, and Total packages: Broader current Security packages include Next-Gen WAF with package-specific workspaces and custom rules. Core Plus and Total also bundle selected DDoS Protection, Client-Side Protection, Bot Management, API Discovery, or Edge Rate Limiting entitlements; these package names are not WAF plans. Fastly Security Starter, Advantage, and Ultimate packages: A second current packaged-offering family maps Essential, Professional, and Premier base platforms to package-specific RPS, workspace, edge-rate-limit, support, and service entitlements. Its package limits are not generalized as standalone WAF tier limits. 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
Best for	Mid-market and enterprise application-security teams protecting mixed web, API, and microservice estates Organizations requiring edge, Fastly-hosted cloud, Kubernetes, PaaS, reverse-proxy, or on-premises deployment flexibility Platform and DevSecOps teams that want APIs, Terraform, simulators, dashboards, and alert integrations	Mid-market and enterprise teams protecting web applications and APIs across hybrid infrastructure. Organizations that need hardware acceleration or self-managed VM deployment with explicit throughput sizing. Fortinet customers that value Security Fabric integration with FortiGate, FortiSandbox, and centralized operations.
Not for	Buyers requiring transparent public numeric pricing or self-service checkout Small teams without engineering ownership for deployment, policy, privacy, and monitoring Buyers expecting dedicated DDoS, bot management, API discovery, client-side protection, and managed operations in every WAF tier	Buyers requiring public numeric prices for every edition and model.

Key features	SmartParse contextual detection for malicious and anomalous request payloads Network Learning Exchange shared reputation and attack intelligence System and custom signals, thresholds, request rules, exclusions, deception, and staged blocking Templated API, account-takeover, and CVE virtual-patch rules on Professional and Premier Premier advanced rate limiting with per-client identification and threshold actions	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	No public numeric subscription amount or binding commercial term is available for any WAF platform. Package-specific RPS, workspace, custom-rule, support, and service entitlements must not be assumed for a standalone or differently packaged quote. Cloud WAF is not available through every current control-panel and package route.	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.

Rank	#3	#1
Context	Security & Privacy / Web Application Firewall (WAF) Software	Security & Privacy / Web Application Firewall (WAF) Software
Protection efficacy	84Employs smart parsing and reputation-based intelligence to mitigate web threats, but overall effectiveness in lower plans is limited by the lack of custom signatures or virtual-patch rules.	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	81Lowers false-positive overhead through contextual analysis, but the policy simulator fails to test advanced rate limiting, deception, or geolocation rules.	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	87Protection is explicitly supported for web applications, REST, SOAP, GraphQL, gRPC, WebSocket, and microservice traffic, which gives the product broad application and API scope for modern estates.	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	75Integrates with DevSecOps tools like Terraform and provides API-driven visibility, but active managed incident response requires a separate professional service engagement.	81Facilitates security operations through integrations with FortiGate and FortiSandbox to enable central threat sharing, virtual patching, and optional managed SOCaaS.
Performance and reliability	75The platform supports several deployment patterns, including edge and customer-managed options, but customer-run environments require compatibility checks, updates, capacity, and network egress, which places reliability responsibility partly on the buyer.	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	87Offers wide deployment flexibility across edge, cloud, reverse-proxy, and agent architectures, alongside integrations with standard notification and alert platforms.	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	53All platforms require custom quotes with no public amount, currency, cadence, commitment, or overage detail, and package-specific support, RPS, workspace, or managed-service entitlements plus optional bot, DDoS, and response products can change total cost outside the base WAF tier.	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.
