SS
Offers flexibility with a kill switch for bypassing Reblaze if needed and provides a reliable Layer 7 defense against attacks
There is still some room for improvement when it comes to bot management from Reblaze because they are relatively new compared to other vendors in the town. AWS WAF, the Web Application Firewall from AWS, has a vast database of bad IP addresses due to its long-standing presence in this business. Reblaze, being a new entrant, is still building its database of bad IP addresses and malicious systems. So, Reblaze needs to work on that aspect. But other than that, I don't think scaling Reblaze has been an issue. There were some initial glitches, but they were all sorted out. So currently, I would say that the bot management and the database are areas they should focus on for further improvement.
Archana Heeralal - PeerSpot reviewer
A good solution to implement web application firewall for applications
There are some lags in Signal Sciences for the web application firewalls. Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic. There is a little bit of complexity with custom rules that should be removed. Signal Sciences should add a feature called rate limiting with multiple options, wherein I can create a rate limiting based on the cookie request or the IP.

Quotes from Members

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

Pros

"It is a highly resilient product that can handle significantly larger workloads and high volumes of traffic with ease."
"The feature I find most valuable is the user-friendly dashboard. It is easy to understand how everything works and it allows you to make decisions quickly and efficiently."
"The most valuable features were the real-time monitoring and the management. With this kind of product, you need a very good management system to allow you to see false positives in real-time; to see what's happening in real-time... The clarity stood out. It was very visible and very easy to navigate; very easy to find the data we were looking for."
"We like the website protection. It's really good. The dashboard is really simple to use."
"Reblaze knows how to manage security. For me as, someone who knows little about security, it's good that I have a firm that optimizes everything according to their standards. It's their responsibility and they are fully hands-on."
"The best thing about Reblaze, for us, is that it has been a game changer because previously, we were using Google's Web Application Firewall, but it wasn't up to the mark."
"Provides mobile app security."
"The real-time monitoring and reporting are very good. There are information updates in their portal every two minutes. They also have the ability to spill it into Sumo Logic, for example. It's very easy to use."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
"The product's most valuable feature is its ability to set up the rules easily."
 

Cons

"We have multiple products behind different instances of Reblaze. We have one instance for staging and then we have a production instance for multiple products. One of the things that we have requested is a unified view panel, so that we can see each of the instances in a unified view. That way, we won't have to go bouncing from instance to instance."
"It would be beneficial if it had a workflow or a feature that could fine-tune settings based on high-level requirements."
"I would like to have seen more automated reports. Maybe it has been improved in the last year and I'm just not aware of it. But from a managerial point of view, you want a summary report, a weekly report: How many attacks were blocked? How much bandwidth was saved due to the caching mechanism? What were the top-ten attacks that were tested on the network, etc? I could most likely have found all that data if I logged in to the system and ran different reports. It would be very helpful to get a management report on a weekly basis."
"The WAF features are not as granular as we would expect from a WAF system. There should be more granularity and in-depth rules, out-of-the-box."
"Up to now the only cons I could find is sometimes getting change management back on track, because it's a company that evolves, and sometimes I don't have the same needs that they have. But besides that, up until now, I am really pleased with their service and I've also recommended them to some of my clients."
"The next release should have next-generation automation."
"Some of the settings on the dashboard are confusing."
"They have an interface that you have to adjust to. That is a bit of a downfall because I expect an interface to be very intuitive for someone who knows little about security. But if you know about security, the interface is wonderful."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
 

Pricing and Cost Advice

"I believe that for the six instances we have right now, it's costing us $16,000 per month."
"On a monthly basis we pay $750."
"We found the cost to be a bit on the higher side, starting at approximately three to four thousand dollars for a small configuration."
"There is still some room for improvement when it comes to bot management from Reblaze because they are relatively new compared to other vendors in the town."
"Signal Sciences is pretty cheap compared to other solutions."
"The product has an affordable cost."
"The pricing is 50% less than Akamai."
