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

"The product is very good, it's so easy to do the deployment, the installation is very straightforward, you can't even compare it to others on the market, and the pricing is very good."
"Imperva is one of the best, if not the best, and almost every feature in Imperva Application Security Platform works really fine and addresses what enterprises are battling, shaping the security culture of the digital world."
"The most valuable feature of Imperva DDoS is to make our website available for our customers' requests 24 hours a day."
"Imperva is really amazing, feature wise and performance wise."
"It is an effective threat mitigation tool."
"The most valuable features for us are the DDoS and Bot."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"Imperva Application Security Platform positively impacts us because we have a critical website, so by placing a WAF of Imperva's quality, it allows us to have visibility and granular control over the various attacks that can occur on the website."
"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

"I would suggest that Imperva Application Security Platform should include new features combined with AI."
"One improvement I would like to see in Imperva Application Security Platform is the ability to fail over to different sites for my same application."
"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."
"We had an issue when securing the web applications for DDoS protection."
"I am not sure if this application has a policy where you can create your custom policy and run it as our firewall. We should have some ability to also create some custom policy, then run it as a firewall."
"Incapsula: Allow easier scripting of firewall rules."
"The tool's UI is complicated. It would be best to have a more accessible UI dashboard to make the job easier."
"It would be useful if the solution used more intelligence in attack protection. For example, firewalls are to be dependent on the configuration, but if they could have some data science around it the solution would be even better. The profiling of the traffic, and making decisions surrounding that should be intelligence-based, instead of being based on the configuration of the firewall itself."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"It is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."
"We are satisfied with the pricing."
"It is expensive."
"It is not expensive compared to the other similar solutions in this category."
"Imperva Web Application Firewall is expensive."
"The license is on a yearly basis."
"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."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
