Same-subcategory comparison
Compare buyer fit, pricing, capability depth, and purchase constraints within one buying category. A higher score is not a universal winner.
Comparison summary
These conclusions apply to this subcategory and the buyer conditions shown here. They do not make one product universally better.
| Dimension | Azure Web Application Firewall | Fastly Next-Gen WAF |
|---|---|---|
| Pricing and trial |
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.

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.

| Rank | #4 | #3 |
| 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. | 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. |
| 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. | 81Lowers false-positive overhead through contextual analysis, but the policy simulator fails to test advanced rate limiting, deception, or geolocation rules. |
| 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. | 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. |
| 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. | 75Integrates with DevSecOps tools like Terraform and provides API-driven visibility, but active managed incident response requires a separate professional service engagement. |
| 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. | 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. |
| 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. | 87Offers wide deployment flexibility across edge, cloud, reverse-proxy, and agent architectures, alongside integrations with standard notification and alert platforms. |
| 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. | 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. |
