Fortinet FortiADC is chosen for reliable load management, security, and support, offering moderate ROI and essential performance.
Sentiment score
6.3
Users report Imperva's significant ROI, citing cost recovery, DDoS protection, reduced cloud bills, and improved efficiency and compliance.
The alert system is efficient, sending alerts within a fraction of a second if any power issues arise.
They know how much money they are losing while the system is down, so by increasing the possibility of not having a down website or web application, return on investment can be calculated easily.
 

Customer Service

Sentiment score
6.1
Fortinet FortiADC customer service is praised for effective support but varies in response time and relies on ticket prioritization.
Sentiment score
7.2
Imperva's customer service is praised for expertise but criticized for inconsistency, with recent improvements noted by some users.
The support team is knowledgeable and efficiently assists with automation and configuration problems.
The service is helpful yet not excellent.
I would rate the technical support of Imperva DDoS as ten.
 

Scalability Issues

Sentiment score
7.5
Fortinet FortiADC provides scalable solutions with virtual and cloud options, though performance varies by model and infrastructure needs.
Sentiment score
7.9
Imperva Application Security Platform offers strong scalability and reliability, though costs and on-premises flexibility may present challenges.
It is scalable for some versions, however, as components reach their end of support, upgrades are necessary to maintain scalability.
99% of customers are using the cloud version of Imperva DDoS protection, so they just purchase the new license and scale as needed.
 

Stability Issues

Sentiment score
8.2
Fortinet FortiADC is praised for stability, reliable operation, effective support, and minor issues resolved through firmware updates.
Sentiment score
7.8
Users find Imperva Application Security Platform reliable and stable, rating its stability highly despite occasional minor issues.
The support system is reliable when issues like automation or configuration arise.
The stability of Imperva DDoS is very good, as it seems they have a lot of servers around the world.
 

Room For Improvement

Fortinet FortiADC needs advancements in algorithms, UI, support, documentation, scalability, features, pricing, licensing, performance, cloud, and AI integration.
Imperva needs UI improvements, competitive pricing, better integration, real-time analytics, and enhanced support for efficiency and transparency.
The limitation of managing all components and the differing versions pose challenges.
If I need design help, they do not assist; they say it is a design issue they cannot support, and I must approach the system integrator.
Maybe Imperva DDoS could use endpoints to get information about the attacks before they commence from the endpoint level or establish cooperation with endpoint vendors to share this information.
 

Setup Cost

Fortinet FortiADC is affordable compared to competitors, with flexible licensing, varying costs, and potential discounts based on configurations.
The Imperva platform's pricing is competitive with advanced features, ranging from $5,000 to $10,000 annually and no setup costs.
This solution is quite expensive compared to Kemp.
I would rate the pricing of Imperva DDoS as five, where one is very cheap and ten is very expensive.
 

Valuable Features

Fortinet FortiADC excels in load balancing, security, and ease of integration, offering scalable, reliable, and comprehensive traffic management solutions.
Imperva's platform offers robust security features, user-friendly integration, real-time analytics, and scalability for diverse enterprise protection needs.
I use server load balancing and employ layer seven features, which provide more granular traffic shaping and detailed logs.
FortiADC provides load-balancing capabilities needed for integration with other Fortinet platforms.
I have utilized Imperva's Intelligent Traffic Filtering feature. This feature helps me understand how the attack is progressing and what is happening inside the requests to our website.

Integrates load balancing efficiently within existing technology environments
FortiADC provides load-balancing capabilities needed for integration with other Fortinet platforms. It allows for the creation of virtual IPs and applying various algorithms for traffic management. Although it offers fewer algorithms than competing platforms like F5, its capability to manage load balancing makes it valuable. The security features depend on the environment, relying on firewalls like FortiGate.
