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

"I would say compare it to other solutions in the marketplace feature by feature and see how Incapsula reporting and analytics dashboards compare and bot control compares – their solution for bot control is pretty good – and check those features with other enterprise level solutions, you get a lot for your money."
"The valuable features of Imperva WAF include its effective security breach prevention through automatically updating rules."
"This product is a reliable defense from malicious attacks on a network environment."
"Our ROI is about 45% since deployment on reduction of our cloud bill."
"There is a quick switch between any of the the nodes if something goes wrong, where there's a there's an attack against a specific area. The security setup is reasonably easy. It's not a problem to do setups and rules and integrations. And, yeah, just the the back end team is also very willing to insist if there's questions that that we cannot answer or with these questions that we do have"
"Setup was straightforward, very simple. I only entered the domain and Incapsula returned the DNS data that I needed to change for the protection to be configured."
"There are a number of features that are valuable such as the account takeover and various antivirus features."
"Imperva Application Security Platform has helped reduce incidents, save time, and improve my organization's security posture with specific measurable outcomes and metrics."
"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

"The user interface could be better."
"They guarantee to fix your problem within 15 minutes, but they don’t always keep their word."
"Their portal is very limited and needs improvement."
"Support is one thing I wish Imperva could improve."
"I have found some issues with caching; seems to be inconsistent."
"Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning."
"I would like to have support for SSL management and secure DNS."
"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"Everybody complains about the price of this solution."
"The price of Imperva Web Application Firewalls is expensive compared to others."
"I rate the product price a four on a scale of one to ten, where one is a low price, and ten is a high price."
"It's an excellent product, but it can be very costly."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."
"The price is high compared to other solutions like FortiWeb."
"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."
