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

"Imperva is a Gartner leader, so its scalability, performance, and features are excellent."
"It fits our requirements, as well as our budget."
"The solution is very good at intercepting traffic before it gets to our data centers."
"I would recommend this solution to others because it is pretty simple to implement, and you don't need a dedicated WAP technician to maintain this solution."
"The bot management features are very effective, as they help filter unwanted traffic using keywords."
"Deployment is simple and very fast."
"Incapsula can help to hide the real origin and provide access control over different pages, and it can protect the website from being attacked."
"I would encourage people to implement Imperva Incapsula, as it is a very mature, easy to use, and reliable solution."
"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."
"It seems to provide a bit of useful information on website health."
 

Cons

"They can provide an option to create reports, automatically import the entire report, and create rules again. In a real-life crisis, it would be helpful to be able to import a report and generate security rules from that report. I should be able to create a simple query and import the reports automatically. It can maybe also tell us the format of the report."
"Support is one thing I wish Imperva could improve."
"An Incapsula website configuration instance can be in a "Pending DNS changes" state, where further work is needing to be done by the customer, while website access is otherwise fully functional."
"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."
"Imperva now offers add-ons to add functionality, but I would like to see these included in the product, even if it would cost more."
"Licensing should be improved. Most of the clients aren't happy. It's expensive."
"We would like them to hire people in Sweden because it's quite hard when people are sitting in the UK or Belgium because some of the customers really want them to be local."
"Imperva Web Application Firewall can improve by adding more features to the dashboard. increasing the visibility of the real-time events, besides configuring the administration itself."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."
"Varies depending on the needs of the customer."
"The tool is expensive."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"It's an excellent product, but it can be very costly."
"It is expensive."
"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
