Dimension	Barracuda Web Application Firewall	Fastly Next-Gen WAF
Pricing and trial	Physical Appliance Amount unverified — check official pricing Virtual Appliance Amount unverified — check official pricing Physical and virtual appliance pricing is configured through Barracuda and authorized channel partners. Physical software is licensed for an agreed monthly or multi-month or multi-year period, while Vx capacity is licensed by CPU cores. AWS provides separate BYOL, hourly PAYG, and throughput-metered routes; only currently visible instance-bound PAYG rates are retained below. Energize Updates is required, while Advanced Threat Protection, Advanced Bot Protection, and Active DDoS Prevention are separate subscriptions. Barracuda authorized channel partner: Barracuda's current product description states that end customers purchase the physical or virtual appliance product through authorized channel partners. Public numeric appliance and Vx prices were not verified. AWS Marketplace PAYG: A current AWS Marketplace route deploys the exact virtual appliance as an AMI and charges hourly by EC2 instance dimension. The listing still uses the former CloudGen WAF name; Barracuda version 12.2 documentation says public-cloud images are now branded Web Application Firewall. AWS infrastructure costs may apply separately. AWS Marketplace BYOL and metered: Barracuda documents BYOL and throughput-metered AWS licensing in addition to PAYG. BYOL requires a separately obtained Barracuda token and leaves AWS infrastructure charges; metered pricing depends on total bandwidth. No current bound numeric rate was retained for either route. Microsoft Azure Marketplace: The current virtual appliance is deployable in a customer Azure tenant through PAYG or BYOL images. No current bound public Azure amount was verified. Barracuda WAF-as-a-Service: A vendor-operated SaaS WAF with its own Advanced and Premium license plans. It can import appliance configuration, but it is not the physical or virtual appliance edition evaluated here. Full profile	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

Category buying score	79Joint highest score	79Joint highest score
Rank	#2	#3
Context	Security & Privacy / Web Application Firewall (WAF) Software	Security & Privacy / Web Application Firewall (WAF) Software
Protection efficacy	82The appliance blocks application-layer threats using dual positive and negative security models and prevents data loss via outbound masking, though advanced threat protection requires an optional add-on.	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	78Automated application learning and vulnerability scanner integrations simplify virtual patching and improve policy accuracy, though manual policy verification is still needed during staging.	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	86The product explicitly protects web applications, REST APIs, XML, JSON, and mobile backends, which gives it broad application and API coverage, although the facts do not add container-native enforcement as a core appliance edition.	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	80The product includes REST API, infrastructure automation, dashboards, log export, and SIEM integrations, which supports operational workflows for security teams, but the facts do not establish built-in response orchestration beyond those interfaces.	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	75The product offers physical, virtual, AWS, and Azure deployment options, plus load balancing, caching, and compression, which can support reliability planning, but capacity is bounded by appliance model or purchased CPU cores rather than an unlimited scaling model.	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	86The platform offers flexible customer-controlled physical, virtual, and public-cloud deployment paths, including AWS and Azure, but lacks standard integrations for direct SaaS-managed Kubernetes 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	62Commercial terms are quote-based with no verified public numeric starting price; Energize Updates is required and Advanced Bot Protection, Advanced Threat Protection, and Active DDoS Prevention add separate subscription 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.
