We used to have to bypass on the firewall, proxy, and IPS; now we can do it in one place
For us, 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. Another thing is SNI. A10 intercepts all the traffic according to the SNI, the server name indicator. It would be better if it intercepted traffic according to the IP addresses. A10 can only understand that a website is within the banking category or the website is in the social media category, according to the SNI. Without SNI, there is no way to understand it; there is no bypass operation. It would be better if worked without SNI as well. Also, the solution comes with web categories like banking and social media. There are suspicious URLs, malicious URLs, etc. It would be better if it had an application category as well. For example, it would be helpful if we had the chance to bypass all Office 365 applications: OneDrive, Skype, Outlook, etc. According to Microsoft, we need to bypass SSL for all Office 365 applications but we need to create custom categories and put all the Microsoft URLs in them and then we can bypass. It would be great if an application category could recognize Dropbox, for example. For now, we have to put the Dropbox URLs in one custom category and bypass them. Application categories could be very useful.

Identifying compromised traffic and securing data has been a significant advantage
One of the most beneficial features of F5 BIG-IP Local Traffic Manager (LTM) is its ability to identify compromised traffic and its capabilities in authentication. Additionally, the security aspect of it provides a significant advantage as it helps us secure our data, which is a major investment and benefit for us. Before using this system, we had difficulties in storing our data and managing the traffic that comes in and out.

Quotes from Members

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

Pros

"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."
"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."
"F5 BIG-IP Local Traffic Manager is a stable and reliable solution."
"The impact of SSL offloading on reducing server load and latency is very much positive because whatever traffic we receive, we encrypt at our F5 BIG-IP Local Traffic Manager (LTM) level, which has definitely reduced the additional load and SSL decryption load on the servers, so it has very much helped us and it is very smooth; it will not take much time and will not impact our regular traffic."
"I have never faced any stability issues with F5 BIG-IP Local Traffic Manager (LTM)."
"The configuration and integration into the AWS environment was pretty easy."
"Valuable features include Link Controller and Server Load Balancer."
"It helps us recognize sessions from certain IPs that are authorized to manage the application. This is a function we haven't found anywhere else."
"The product is quite flexible."
"The combination of ADC and WAN is the most valuable feature."
 

Cons

"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."
"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."
"Not everything is intuitive."
"F5 BIG-IP Local Traffic Manager is expensive. Pricing needs to be improved."
"While the licensing is good through the AWS Marketplace, it is more expensive than what you could buy yourself."
"The pricing model has caused some frustration. My clients implemented the solution and later wanted to upgrade the features but the pricing structure was complicated. There are other solutions with better pricing models."
"The initial setup can be complex - it's quite flexible in terms of configuration, but the person configuring it needs to understand the application side, the network side, and the server."
"F5 BIG-IP Local Traffic Manager could improve by having an FNI feature for a single source to multi-domain load balancing."
"The initial setup can take a long time."
"Improvements should enable customers to build a tailor-made solution in the future through a service portal."
 

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."
"Our licensing costs, yearly, are just under $15,000. Your initial cost of acquisition is obviously going to be more than $15,000..."
"We always pay for support. Any organization of our size who doesn't is asking for problems."
"It is sort of a commodity product. A load balancer is a load balancer. What will be, at the end of the day, the cheapest option or have the best performance, that is what it will come down to."
"This solution comes with a standard license, and there are also extra licenses that can be obtained. The licenses are purchasable for durations of one, two, three, and five years. The hardware is something to consider when purchasing"
"F5 BIG-IP can be expensive, although there are trial versions available which are helpful to find out if the solution is right for your company."
"Try to negotiate all the software features that you require upfront."
"We have found the pricing and licensing on AWS to be competitive."
"It's fair, it's not too expensive. Maybe just a little high."
"If your IT budget is good, go for it."
"The cost is high for this product, so it's not suitable for small customers, e.g. those with small environments."
