I like the content monitoring feature which I haven't seen in other WAF solutions.
We never used to know about threat and attack signatures. By using Imperva WAF, we could identify our weak points where an attacker was trying to... Read more →

Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"We use Imperva DDoS to stop DDoS attacks and reduce the amount of unwanted queries against web services or web scraping.""It's very pretty easy to onboard the URL.""It blocks all types of attacks.""Real-time monitoring is also a great tool, as you may watch several parameters in real time.""On the site security, I can see which countries have incidents, whether it was a robot attack, a real human user, or non-human user.""The dashboard is good and user-friendly.""IncapRules is one of the most valuable features, as you can create your own security and access control rules on top of your security policy. Using IncapRules we were able to easily block Layer 7 DDoS attacks several times.""The three-second service level agreement is already better than the competition."

More Imperva DDoS Pros →

"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application.""The product's most valuable feature is its ability to set up the rules easily."

More The Fastly Next-Gen WAF (powered by Signal Sciences) Pros →

Cons
"It's quite expensive.""Some maintenance must be performed by our IT team.""It needs to be improved every time there are new attacks.""I miss being able to integrate the dashboard with other BI tools we are using. We have to export and import data to be able to present it, and doing so is a lot of work.""Imperva DDoS does not provide version control.""Imperva always needs to adjust to new versions of cyber attacks, it needs to be faster, improve the resiliency of the software of the solution.""The solution should integrate with something that looks at continuous security management.""I would like to see automated reporting to improve visibility."

More Imperva DDoS Cons →

"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic.""The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."

More The Fastly Next-Gen WAF (powered by Signal Sciences) Cons →

Pricing and Cost Advice
  • "For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
  • "​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
  • "The data packages are higher than our needs so we end up paying for data that we don't use."
  • "The cost is on par with other solutions such as Cloudflare and Akamai."
  • "It is not expensive compared to the other similar solutions in this category."
  • "It is a very expensive solution. The price is very high. A lot of customers tell us that they would love to use Imperva more. I have some customers who have 50 websites, but they have only 10 websites on Imperva because of the price. They would love to have all their websites running through Imperva, but they can't. They have to choose the more critical websites to protect because the price is very high. It is a very good product, but it is too expensive. If you buy a plan for 20 megabytes and you don't consume all of your 20 megabytes, it is okay, but if you consume more, you are charged for the superior traffic."
  • "The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
  • "It is expensive."

    • More Imperva DDoS Pricing and Cost Advice →

  • "Signal Sciences is pretty cheap compared to other solutions."
  • "The product has an affordable cost."

This test was designed to bypass security controls in place, in any possible way, circumventing whatever filters they have. Given the rise in application-level attacks, the goal of the test was to provide IT managers of online businesses with a comparison of these WAFs against real-world threats in simulated real-world conditions. Zero Science Lab is a Macedonian Information Security Research and Development Laboratory that specializes in information security hardening, consulting, network security, vulnerability research, software and hardware security assessment, penetration testing, malware analysis, forensics and much more - https://www.zeroscience.mk Background In February 2013, we conducted the first comparative pentest analysis of the CloudFlare, Incapsula and ModSecurity Web Application Firewall (WAF) solutions. The goal of a WAF is to block hacker attacks / unwanted malicious traffic to your web application with as few false positives as possible. Since then, all three vendors had replied to the findings, applying patches to the discovered bypasses and improving their products to protect their… Read more →

    Reviews from Real Users

    Below are some reviews and helpful feedback written by Imperva DDoS users.

    PeerSpot user, Etienne W., CDN & Cybersecurity Engineer - Web performance & security at CDN Tech / Ecritel, says, “It is a good solution that allows us to protect websites. It is stable, scalable, quick and easy to use.” He goes on to explain, “WAF protection works almost out-of-the-box. The Anti-DDoS mitigation in less than 1s, I saw it many times in production, I can say it works. CDN has high performances, and the Smart Caching mode is really "smart" (you can do some efficient caching even if you're not a specialist). Its unique interface for managing security performance and ease of use are the most valuable features of this solution."

    An IT Senior Manager at an outsourcing company mentions, “The most valuable features are DDoS protection. The Incapsula [Imperva DDoS] environment helps us monitor all the web activity. All the web activity is passed through their WAF cloud services, then that can help us to monitor those activities. That can help protect against DDoS hacking.”

    Another PeerSpot reviewer, Ben D., Sales Executive at EVVO LABS, comments, "Imperva Incapsula [DDoS] has many valuable features. One, it protects the top 10 OWASP vulnerability, the open web application software platform, this is standard. Secondly, it protects against broken authentication. As well, it has remote execution of code."

    A Solutions Architect at a financial services firm states, “The solution's most valuable aspect is that it is easy to configure. The solution keeps itself up to date itself and there's no customization that we need to do. It makes it extremely easy and cuts back on the amount of work required, and saves us on man-hours.”

    The Fastly Next-Gen WAF (powered by Signal Sciences) provides web application and API protection, RASP, rate limiting, bot protection and DDoS purpose built to eliminate the challenges of legacy WAF.
