Featured Reviews

Pranay Jain - PeerSpot reviewer
Senior software engineer at Simplifyvms
Edge caching has transformed response times and delivers faster candidate data globally
Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.

Comprehensive web protection has secured public apps and supports advanced audit requirements
Fortinet FortiWeb Cloud WAF-as-a-Service has multiple valuable aspects. The WAF solution secures whatever public domains have been published by the public platform or internal servers exposed to public users. Firewalls have limitations, which is why I suggest using a WAF solution. The firewall provides the same features but in a limited edition. When discussing the SaaS platform or Layer 7 layer of security, you will receive multiple benefits. Firewalls have limitations with signatures, bot protection, and DOS protection. Fortinet FortiWeb Cloud WAF-as-a-Service is a dedicated WAF product that handles all DOS protection, bot protection, API security, endpoint connectivity, signature-based support, and top 10 OWASP support. Multiple features are available. AI and ML-based technology is available in almost every tool today. When discussing troubleshooting, there are AI models that will solve your problem and provide information. AI is helpful because it will give you proper information regarding errors and troubleshooting.
