Featured Reviews

Nikolay Dimitrov - PeerSpot reviewer
Cyber Security Engineer at Paysafe / IBM
Easy to configure and blocks bot attacks for web users
The solution is deployed on the F5 cloud. The solution's real-time analytics help you see what has been blocked. It helps to see whether the attack category was an automation attack or a fake browser. F5 Shape Security has a normal dashboard. We are doing F5 Shape Security migrations for 30 customers. F5 Shape Security uses Javascript. For a lot of competitors, the Javascript can be reverse-engineered by attackers to bypass the protection. F5 Shape Security has machine learning authentication of the Java script. If you had hacked it, the encryption would have been changed. It's really hard for attackers to reverse engineer the F5 Shape Security JavaScript. Overall, I rate the solution a nine out of ten.

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.

Quotes from Members

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

Pros

"The most valuable feature of the solution is the ease of configuration."
"F5 Shape Security's most valuable feature is performance."
"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."
"We like the website protection. It's really good. The dashboard is really simple to use."
"Reblaze has saved us money by optimizing server usage and blocking malicious bots."
"The main feature is using the rules and being able to see the traffic. It helps us find malicious traffic."
"Provides mobile app security."
"I very much like the elastic search and reports, allowing us to have a 360-degree view of the customer's activities and enabling us to track down any suspicious bots."
"Reblaze provides us with a solution we can count on."
"It is a highly resilient product that can handle significantly larger workloads and high volumes of traffic with ease."
 

Cons

"I want the solution's custom exclusion rules to be more granular."
"The tool's price is high."
"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."
"The interface on the dashboard could be improved. Some of the settings are confusing which makes things difficult when you're trying to get a handle on the product."
"There is room for improvement in helping us understanding session management... We want Reblaze to catch and identify everything. We want to see the various devices doing one activity and to see, in a timeline, what's happened. We would like to see a more human-readable display to understand what's happening in the web app."
"The next release should have next-generation automation."
"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."
"Perhaps the automatic reporting could be better. I would like to have seen more automated reports."
"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."
"Some of the settings on the dashboard are confusing."
 

Pricing and Cost Advice

"The solution is moderately priced."
"On a monthly basis we pay $750."
"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."
"We found the cost to be a bit on the higher side, starting at approximately three to four thousand dollars for a small configuration."
"I believe that for the six instances we have right now, it's costing us $16,000 per month."
