The SSL decryption successfully decrypts at a rate that has minimal to no impact on our end users
With the Thunder SSLi, we're better protected. We can stop use of VPN and proxies. We are better protected against dirty traffic coming back to our schools. Having a secure decrypt zone with the equipment lowers the chances that our security infrastructure could possibly miss an attack. It gives us insight into the actual traffic that a student is following. What's the value of identifying possible risks or possible intent based on unencrypted traffic where you have insight to what the student's intent may be? E.g., anonymous bully reporting. It's invaluable to be able to leverage that insight and data to maybe bring help or avert a possible bad circumstance. It's something that's very important to us that this type of system gives us insight into that. For terms of ease of use, it's fairly simple. My analysts tell me that they don't mind getting in there. It was something new that we had to throw on their plate. Every time you add a new element and a new level of complexity, your analysts will look at you like you're crazy, Our plan was originally to use our native firewalls to do the decryption. Unfortunately, that was a feature set which was added on afterward. It just ended up bogging down our system. That is the reason why we had to add the extra hardware. Once the team understood that, the UI was intuitive and a huge help. We use the solution’s Harmony analytics and visibility controller. We have been able to proactively engage and deescalate situations with it. We love Harmony’s traffic management capabilities because it is centralized management. It has a rich analytics capability. This allows us insight into the aggregate performance of all the boxes. so we can possibly leverage any resources available to enhance the environment. We love the single pane of glass traffic management. Single pane of glass is huge, centralized logging. It is the buzzword that everyone is talking about right now, except what nobody seems to take into consideration, is that an analyst only has two eyes. The administration piece of it is huge. It allows us to not just look and get the information, but also cipher it, which is actionable. Looking at logs all day is great, but you can stare in the matrix so long before you want to get in the game. This single pane of glass allows us to look at information that's actionable.

Boosts Security Measures with Easy Deployment and Implementation
Regarding areas for improvement in Symantec Web Application Firewall, I think they can enhance the features they currently focus on, as there are various types of web applications, and it would be great if they could develop features to cater to all these types. For example, a feature to scan for unauthorized plugins or extensions could let us know if those extensions are authorized, unauthorized, or malicious. There's room for improvement in Symantec Web Application Firewall by introducing AI into their dashboard so that we can query the dashboard and fetch data insights, similar to querying ChatGPT for answers. They currently have this feature but can make improvements for better querying to get insights.

Quotes from Members

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

Pros

"Its most valuable feature is its ability to do its job accurately, effectively, and very quickly. The amount of traffic that we have going through our system is astounding... The delay with the SSL decryption turned on is almost unnoticeable."
"With the Thunder SSLi, we're better protected. We can stop use of VPN and proxies. We are better protected against dirty traffic coming back to our schools. Having a secure decrypt zone with the equipment lowers the chances that our security infrastructure could possibly miss an attack."
"We have several proxies in our environment, so we localized internet traffic between these proxies. Instead of getting a really huge proxy box, according to our size, we can use three boxes and share the traffic with A10's load-balancer feature."
"The best feature of Symantec Web Application Firewall is that it is very easy to use, and the deployment and implementation processes are really easy."
"The setup was straightforward."
"The best feature of Symantec Web Application Firewall is that it is very easy to use, and the deployment and implementation processes are really easy."
"The interface is user-friendly."
"The solution has an up-to-date data repository to deal with external threats."
 

Cons

"It would be great if it supported SSL operations according to Active Directory users. For example, if we want to bypass one of the servers or a client's internet access for SSL interception, we have to do it according to the IP address. It would be better if we could do it according to the Active Directory username. A10 says they kind of support that but we haven't tested it."
"I would like them to have a better UI (better universal design)."
"There is one thing I would like to see changed. In their features for setting things up, there is a templating system that would normally assist clients. However, we had a better time setting up the device either through the command line or through the interface and not using the templates that were pre-installed. So there is room for improvement to the templates for initial installation."
"I'm not convinced that it's necessary the best solution going forward in the future."
"There's room for improvement in Symantec Web Application Firewall by introducing AI into their dashboard so that we can query the dashboard and fetch data insights, similar to querying ChatGPT for answers."
"It would be an improvement if the management dashboards were not reliant upon Java."
"There's room for improvement in Symantec Web Application Firewall by introducing AI into their dashboard so that we can query the dashboard and fetch data insights, similar to querying ChatGPT for answers."
"Sometimes scanning slows down the endpoints."
 

Pricing and Cost Advice

"When you purchase the equipment, you purchase the licensing and warranty. It's all fairly standard. We haven't been caught with anything surprising."
"We always pay for support. Any organization of our size who doesn't is asking for problems."
"Our licensing costs, yearly, are just under $15,000. Your initial cost of acquisition is obviously going to be more than $15,000..."
