Stability Issues

7.9
Imperva Application Security Platform is praised for stability and reliability, with minor issues occurring mainly during high traffic.
Sentiment score
7.6
NetScaler is highly rated for stability and performance, with some recommending regular maintenance for optimal reliability.
It is also a stable product without much glitch or downtime.

One notable drawback is that, unlike Fortinet, which offers fast track labs and continuous enablement, Imperva Application Security Platform lacks lab access and fast track labs for enablement and product advertising.
CTO at Malam Engineering PLC
We experienced downtime or crashes with Imperva Application Security Platform when traffic went really strong or fast because people tried to get tickets.

Room For Improvement

Imperva Application Security Platform needs better integration, simpler dashboards, improved AI, and enhanced user interface for higher satisfaction.
NetScaler needs improvements in usability, stability, security integration, and support while enhancing documentation, pricing transparency, and deployment processes.
To convince my clients, a purely on-prem solution would be ideal since they are financial institutions.
CTO at Malam Engineering PLC
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.
Head of Sales Services Department at a comms service provider with 51-200 employees
Regarding return on investment, ROI, I can say it is noticeable with Imperva Application Security Platform.

Setup Cost

Imperva's Application Security Platform has high, complex pricing, yet some find it competitive for its security benefits and enterprise flexibility.
NetScaler pricing is high but offers strong features; cost-saving options include alternatives or negotiating multi-year subscriptions.
I would rate the pricing of Imperva DDoS as five, where one is very cheap and ten is very expensive.
Head of Sales Services Department at a comms service provider with 51-200 employees
the setup cost was high, with the hardware installation in the data center being particularly expensive.
Cyber Security Product Owner at a energy/utilities company with 10,001+ employees
We have noticed faster response times and fewer security alerts because after doing some custom policy tuning, everything seemed to be aligned and we have fewer attacks to monitor and fewer alerts to monitor.

Valuable Features

Imperva Application Security Platform offers robust threat protection, user-friendly interface, and comprehensive reporting for enhanced web security management.
NetScaler provides flexible deployment, security enhancements, and integration with Citrix for efficient application delivery and robust traffic management.
The API security feature is particularly valuable because most attackers do not try to come in from where it is expected.
Senior Cybersecurity Consultant at Cyberoutcome Limited
If someone attempts to access the server, the WAF blocks that SSRF alert, or RCE, Remote Code Execution alert, blocking immediately based on the signature, not only by the payload or the IP address.
SOC Analyst L1 at CMS-IT-SERVICES-PVT-LTD
It reduces the DDoS attacks and reduces the attacks from threat actors, including SQL Injection and zero-day attacks, by using dynamic application profiling from Imperva.

Application protection has improved and reporting and dashboards still need refinement
I believe Imperva Application Security Platform should have a more interactive wizard. While the dashboard is good, it could be more eye-catching. Based on my perspective, I recommend modifying the dashboards, especially the main dashboard where I can see the traffic hit count, alerts, and other latest information. In terms of reporting, I find it challenging to create reports; in my earlier days, it was difficult. Over time, I have learned how to create reports, but it should be easier to do so. I have used other tools such as firewalls or SolarWinds, where creating a report is straightforward and does not take much time, unlike in Imperva, where I have to add many elements. Modifications in the integration aspects would also be beneficial.

Load balancing and secure access have supported complex migrations and automation at scale
NetScaler has positively impacted my organization because I work for a system integrator and deploy it for customers. Many customers are really happy with NetScaler, except for the pricing, as Citrix has changed a lot of their pricing in the last two or three years when they transitioned to Cloud Software Group. However, despite that, I know customers are really satisfied with the technical capabilities that NetScaler provides. While I do not have specific outcomes or metrics from my customers, I think using Core Logic has made it much easier for the big municipality I mentioned to implement NetScaler as a total solution, thus speeding up their automation. There are likely many benefits, but I lack benchmarks or timing figures to quantify that.
