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.

It's not easy to get out once you're in
Sitelock may perform a useful service, but be wary of giving them your credit card information. When you sign on for the paid service, Sitelock: * Hides (makes it difficult to find) that they default the auto-renew (you can't sign up without agreeing to have them automatically bill your credit card every year). * Hides (makes it difficult to find) how to stop auto-renew: * You can't just stop auto-renew from your billing panel, the way you can with reputable businesses. * You have to hunt their website for a link (in extremely small font) to the page which contains instructions for cancelling. * When you get to that page, turns out it's the 5000+ word "Terms of Service" document, which you have to scour to find a phone number. Then, you have to call and get put on hold (or if you like, they will call you back three days later). Once you finally get through, you have to jump through a lot of security hoops. All of the above, just to cancel the service. Their product may or may not be OK, but be forewarned that with Sitelock, it's not easy to get out once you're in.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"There are some features that are configured by default, so even without doing much, it can still provide a level of protection."
"Technical support was very helpful."
"The most valuable features of the Imperva Web Application Firewall are performance and flexibility, and we can extend or customize the box itself."
"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."
"It is an effective threat mitigation tool."
"Imperva anti-DDoS protection has the well-known value of having lots of distributed nodes around the world, making it the best value for DDoS protection."
"I suggest others looking into using Imperva Application Security Platform consider it as the best solution."
"Incapsula can help to hide the real origin and provide access control over different pages, and it can protect the website from being attacked."
"It seems to provide a bit of useful information on website health."
"Not only did SiteLock's website scanner find the issue with my website, but with SiteLock I was able to implement a security system to prevent future breaches."
 

Cons

"They can provide an option to create a report, automatically import the entire report, and create rules again."
"Its price could be improved. It is quite expensive."
"If they can bring in generative AI features, that would be useful."
"Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning."
"There could be some limitations that from the converged infrastructure perspective: when you want to converge with everything and you want Imperva to get there easily because it's not a cloud component. For example, when you want to build servers and you're using OneView to manage your software-defined networks, implementing Imperva right away is not that simple. But if you're doing just a simple cloud infrastructure with servers in there, you're good to go. Also, we are not able, with Imperva, to block by signatures. Imperva by itself needs to be complemented with another service to do URL filtering."
"The only disadvantage of Imperva is that it is a pretty costly solution."
"We've had some issues with them in terms of response times, but overall they are okay."
"They recently separated the WAF and the DAM management gateways in order for each of these to be managed from different areas, so I believe it now requires additional investments for what was previously a single complete solution."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"The price of Imperva Web Application Firewalls is expensive compared to others."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"Pricing could be more competitive."
"It's an excellent product, but it can be very costly."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"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 price is high compared to other solutions like FortiWeb."
"There is a license or subscription renewal that our customers pay."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
