Author infoRatingReview Summary
Staff Engineer at a retailer with 1,001-5,000 employees3.5We chose Fastly Next-Gen WAF for its cloud-based ease, code-managed configuration, and strong anomaly detection, despite a non-intuitive UI and limited support. It's competitively priced, integrates well with CI/CD, and meets our security and deployment needs.
Staff Engineer at a retailer with 1,001-5,000 employees4.5We use Fastly Next-Gen WAF for protecting our public sites after migrating from Akamai for better maintainability and cost savings. It enhances page speed with its unique caching approach but lacks caching support for China users.
Security Engineer-DevSecOps at a computer software company with 51-200 employees3.0The most valuable feature of The Fastly Next-Gen WAF is its easy rule setup and policy control per agent. However, the effectiveness of rules needs improvement, and managing agents can be difficult. We chose this solution for its cost-effectiveness and Kubernetes compatibility.
Security Engineer at Amazon4.0We used Signal Sciences' web application firewall to protect our applications, appreciating its flexible rule configuration but noting issues with lag and complexity in custom rules. It lacks features like rate limiting based on cookies or IPs.
