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 like the ability the product has to detect vulnerabilities quickly, when it has been released in our environment, then displaying them to us."
"It does a scan that performs about 100 checks on web applications and produces a clear report on all of the vulnerabilities that are found."
"What I like most about AppSpider is that it's easy to use and its automated scan gives me all the details I need to know when it comes to vulnerabilities and their solutions."
"It scans all the components developed within a web application."
"The most valuable feature is the reporting, which is compliant with international standards."
"I would say that it is stable, as I am not aware of any major issues."
"The setup is usually straightforward."
"It is really accurate and the rate of false positives is very low."
"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

"One of the challenges I have with AppSpider is that it gives you a lot of false positives, especially when compared to other solutions."
"Integration could be better."
"The solution is too slow. It could take a full day to scan. Competitors are much faster."
"Integration could be better. For example, while doing the scanning, using the recording username and passwords, there are issues."
"The dashboard and interface are crucial and they need some improvement."
"The enterprise interface is too simple. It should be more customizable."
"The performance of the solution could improve. When I compare the speed it is slower than others on the market. There are some tricks we use to help speed up the solution."
"Implementing Rapid7 AppSpider requires scanning and self-identification mechanisms. You can add different types of authentication to each scan."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"The price is pretty fair."
"The licensing cost depends on the number of users."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
"The price of Rapid7 AppSpider cost 9,000 annually but there is limited usage. Large companies are able to negotiate a better price or a better deal for the usage with the vendor."
"AppSpider is closed-source software and you need to acquire a license in order to use it."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
