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.
DejanBlagojevic - PeerSpot reviewer
Mitigates more bot activity when defending web applications than any other vendor but comes at a price
F5 Silverline Managed Services is expensive. You do get world-class quality of mitigation, but I think it is still pricey. You can find similar services, potentially of slightly lower quality, from other vendors like Cloudflare or Akamai for about half the price. When you compare what you get for the money you spend at Cloudflare or Akamai, you do get less protection but you are not dishing out too much for it. On the other hand, at F5 Silverline Managed Services, you do get better protection but, but you are paying double for it. We have had mixed feedback from our clients about this. Most of them would rather pay less for a bit of a lower-quality defense than overshoot their budget. The most common piece of feedback we receive is that the difference in protection levels is not reflected in the price.
Bonieber  Orofeo - PeerSpot reviewer

Microsoft Azure Application Gateway impacts our cost savings while maintaining higher performance. The Web Application Firewall (WAF) in Microsoft Azure Application Gateway has been very effective in protecting applications from security threats. Microsoft Azure Application Gateway helps us manage our AI-driven applications by enabling faster transactions, improving our work.
