ROI

Sentiment score
6.3
Imperva DDoS ROI is complex, influenced by compliance, mitigation, cost savings, and service availability, enhancing financial efficiencies.
Sentiment score
8.1
Radware Cloud WAF Service boosts ROI through enhanced security, reduced costs, minimized risks, and increased operational efficiency.
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.
I wouldn't be able to give a number, but Radware Cloud WAF does save time for our staff due to the automation and excellent detection, which is invaluable.
With our on-prem solution, we spent a lot of time on maintenance tasks, OS updates, and ensuring appliances ran smoothly, but with Cloud WAF, all that is managed by the cloud team, allowing us to focus on alert analysis.
Radware Cloud WAF has helped reduce false positives and efforts, which in turn, improved the total cost of ownership by freeing up time to focus on other projects.

Imperva DDoS support receives mixed reviews but is praised for fast resolutions, 24/7 availability, and improved quality.

I would rate the technical support of Imperva DDoS as ten.
The support provided by Radware's Emergency Response Team is excellent.
We have ERT premium support with a five-minute SLA.
They are usually very fast in response.
 

Scalability Issues

Sentiment score
7.9
Imperva DDoS efficiently scales in cloud environments, though licensing costs and transitions from on-premise can pose challenges.

8.3
Radware Cloud WAF Service offers seamless scalability and integration, effectively handling high traffic for diverse global applications.
99% of customers are using the cloud version of Imperva DDoS protection, so they just purchase the new license and scale as needed.
The scalability of Radware Cloud WAF Service rates as a perfect ten out of ten, as we haven't encountered any scaling issues.
Since it's a Cloud WAF, it is always scalable.
I would rate it nine out of ten in terms of handling the capacity and volume.

Sentiment score
7.8
Imperva DDoS is highly stable with few incidents, rated 8-9 for performance despite occasional cloud-related content delivery issues.
Sentiment score
8.2
Radware Cloud WAF Service is highly stable and reliable, with minor past issues that have been mostly resolved.
The stability of Imperva DDoS is very good, as it seems they have a lot of servers around the world.

The stability of Radware Cloud WAF Service is excellent, and I would rate it as a ten.
There have been no issues with downtime, bugs, or glitches.
 

Room For Improvement

Imperva DDoS needs interface improvements, reliable support, pricing transparency, enhanced features, and better global integration for reduced latency.
Radware Cloud WAF Service needs improvements in integration, UI, reporting, support, licensing, scalability, and tool integration for performance enhancement.
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.
It would be beneficial if we could perform POST requests and integrate our applications more effectively.
The documentation is not up to par, as while the platform's system is robust, the documentation, particularly for API integration, could be more developer-friendly with real-world use cases.
Improving dashboard capabilities to provide this information clearly for management is crucial.
 

Setup Cost

Enterprise users find Imperva DDoS competitive, with zero setup costs; prices range $200-$10,000/month, offering valuable protection.
Radware Cloud WAF Service offers mid-range pricing with modular licensing, extra feature costs, and negotiation flexibility for enterprises.
I would rate the pricing of Imperva DDoS as five, where one is very cheap and ten is very expensive.
Pricing could be more competitive, especially for smaller customers.
I find Radware Cloud WAF to be a quite expensive product compared to others.
The pricing is not cheap; it is expensive, but it is effective.
 

Valuable Features

Imperva DDoS provides robust, cloud-based security with ease of use, real-time monitoring, and comprehensive protection against attacks.
Radware Cloud WAF offers robust Layer 7 protection with advanced features like bot management, DDoS defense, and user-friendly management.
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.
The most important aspect of Radware Cloud WAF is that it is over the cloud, offering a comprehensive solution that includes WAF, API protection, bots, and Layer 7 DDoS.
It has features such as API security that protect against advanced attacks, including business logic attacks.
Radware Cloud has significantly reduced attacks on our applications.

Featured Reviews

DerrickAkankwasa - PeerSpot reviewer
Provide DDoS protection and better security at effective rate
It is expanding its number of data centers for scrubbing traffic. Currently, there is only one POP for cleaning in South Africa. They might add another POP in North Africa, possibly in Nigeria or Egypt. Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning. Increasing the number of POPs across the continent would help address these latency issues and improve overall service. While the platform is already quite strong, there’s always room for improvement, especially in keeping up with emerging trends and new types of attacks. Enhancing security capabilities could be beneficial. Integrating more advanced AI features could significantly improve its effectiveness and help customers leverage these tools more effectively. It would be great to see more focus on AI integration to handle and analyze data more efficiently.
Tanuj-Garg - PeerSpot reviewer
API discovery, bot defense, and DDoS capability optimize application security and development
I see areas in Radware Cloud WAF Service for improvement, specifically in its initial tuning period, because the machine learning model takes two to three weeks for baseline behavior establishment. Closely monitoring alerts during this period is essential to avoid false positives. There's an alert noise issue; during the early stages, we received a high volume of alerts for minor issues, requiring collaboration with the SOC team to fine-tune thresholds and concentrate on genuine threats. The documentation is not up to par, as while the platform's system is robust, the documentation, particularly for API integration, could be more developer-friendly with real-world use cases.
