Featured Reviews

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.
Tomaz Sobczak - PeerSpot reviewer
Signature-based detection, DOS protection, and bot protection
NGINX App Protect is easier to automate and configure, or manage from an API. This is good for securing applications. However, it's not suitable for more complex tasks. NGINX App Protect positively impacted performance changes. There's a cache or it works like a proxy, so it can speed up applications. It can also offload some functions from servers, which NGINX can handle faster.
