Ratings
Cost considerations
Fastly lists a $3,000-per-month Starter tier for the Next-Gen WAF with a 25-RPS ceiling, while higher tiers require contacting sales, making long-term cost forecasting harder. The flat subscription model removes attack-based surcharges, but traffic over the cap can trigger extra usage costs. Overall pricing is mid-range—pricier than pay-as-you-go cloud WAFs yet comparable to other enterprise SaaS firewalls—so the value is fair but not exceptional.

Functionality
Signal Sciences Next-Gen WAF protects web apps and APIs from OWASP Top 10 attacks, bot abuse and other Layer-7 threats through advanced detection and blocking. Native modules, REST APIs and Terraform enable teams to integrate security into build and deploy pipelines while dashboards and alerts give real-time attack visibility. The strong threat breadth, policy flexibility and automation place functionality above average, but absence of code-level scanning keeps it shy of a perfect score.

Compatibility
Signal Sciences agents run on NGINX, Apache, IIS, HAProxy and support Java, .NET, Node, Python, Go, plus integrations for Kubernetes, AWS, Azure and common CI/CD and alerting tools. Deployment just needs a lightweight agent or module, so teams face small setup efforts rather than heavy customization, earning a compatibility score of 4.

User experience
Security staff get a sleek console with intuitive dashboards and wizards that make setup and daily monitoring straightforward, and alerts integrate with Slack or PagerDuty for quick action. Reviewers say the interface is easier than legacy WAFs, but digging into advanced options still takes effort, so the experience is strong yet not top tier.

Customer support
Peer reviews highlight fast, knowledgeable assistance and describe customer service as a key advantage over rival WAFs, with one user calling support “fantastic” and comparisons stating it outperforms AWS WAF on customer service. Limited criticism targets product features rather than support quality, suggesting most issues are resolved without heavy escalation. Absent evidence of 24/7 sub-hour SLAs or dedicated account managers keeps the rating below the top tier.
