Featured Reviews

SachidDoshi - PeerSpot reviewer
Offers a huge signature repository and is superiorly effective in mitigating DDoS attacks
The solution's learning curve can still be further reduced, which presently stands at two or three months. The product has a custom rule set that users can modify and manifest as needed. The vendor can probably shorten the learning curve using cutting-edge technologies like AI. The solution provider can also work around the web applications and identify the toolset that needs to be implemented to deploy the solution in less time. The vendor has launched a SASE product that can function with Cloudflare Web Application Firewall, but many improvements are needed in terms of features, such as the web filtering feature, and CASB has not yet been added.
Ahmed Moamen - PeerSpot reviewer
Protects applications with versatile authentication features
F5 offers a versatile solution that can be integrated with APM in cases where integration with an external IDB is needed. It is useful for authentication backup if the on-prem directory service is unavailable. Additionally, its WAF functionality is valuable for protecting applications from attacks. It is a versatile and strong solution that's easy to understand and deploy.
