Featured Reviews

RONALDO DE MELO - PeerSpot reviewer
Efficient application security while optimizing connections
The initial setup is simple; it is not complex. The configuration itself is simple and can be done in a couple of hours. However, the migration of the system to A10 Networks takes longer due to critical applications. Clients prefer to move them one by one, which is why it takes a significant amount of time. The configuration itself is simple, especially for this application.
Bonieber  Orofeo - PeerSpot reviewer
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) ( /products/f5-big-ip-local-traffic-manager-ltm-reviews ) 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.
OusaidAbaz - PeerSpot reviewer
Integrates load balancing efficiently within existing technology environments
FortiADC provides load-balancing capabilities needed for integration with other Fortinet platforms. It allows for the creation of virtual IPs and applying various algorithms for traffic management. Although it offers fewer algorithms than competing platforms like F5, its capability to manage load balancing makes it valuable. The security features depend on the environment, relying on firewalls like FortiGate.

Quotes from Members

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

Pros

"What I like about Lightning ADC, is that instead of having a big appliance sitting in front of the Kubernetes cluster, Lightning can pretty much go inside of Kubernetes."
"Our clients appreciate that this is a security enabled solution."
"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."
"The BIG-IP’s interface is more intuitive than other GUIs. It is well structured, not overloaded, and does not have too many gimmicks."
"Stability-wise, I rate the solution a ten out of ten."
"It has made it a single entry point for all users, verging across all the VPCs. It is more of an SSO solution versus multitier user loggin."
"Initial setup is easy and pretty standard."
"We are fond of the load balancing feature for DNS and servers."
"The product is quite flexible."
"We have found the consistency of the application always being the way it is supposed to be as its most valuable feature."
"In terms of stability, it is stable."
"The solution enhances performance by efficiently balancing the load across multiple backend servers."
"Simple to use and easy to integrate."
"TSL and SSL offloading are both very good features."
"FortiADC provides load-balancing capabilities needed for integration with other Fortinet platforms."
"The main feature that we use is GSLB (Global Server Load Balancing). GSLB makes the customer's network more reliable by scaling applications across multiple datacenters. GSLB as a disaster recovery solution can direct traffic based on site availability."
"The GSLB, the DR side, is the best part. Because we had our main side in one city, we created another, and we had a complete MPLS over the internet. We used the GSLB and data loss for our business applications."
"The product has flexible and interesting licensing options."
"Although FortiADC has multiple features that I like, the global DNS is the most helpful. It is primarily useful for customers with huge environments and at least two data centers. FortiADC can act as your DNS server. It can check which data center has the lowest latency, and route traffic to that one. It's an intelligent DNS."
 

Cons

"The support from A10 should be improved."
"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"F5 BIG-IP Local Traffic Manager could improve by having an FNI feature for a single source to multi-domain load balancing."
"LTM's cloud capabilities could be improved. Cloud providers all offer load balancing, but you can't get the same level of security. F5's cloud service is still not on par with its on-prem service."
"Internet and cloud support could be improved."
"If they made it easier for engineers to get F5 training then it would be better."
"If we decide to migrate to the cloud, I don't think that BIG-IP is a good solution and we probably won't use it."
"My only point of contention would be that it is a little pricey."
"Certificate management needs improvement. I would like automated deployment of new certificates without manual intervention to be in the next release of this product."
"We would like to see load balancing between the cloud and the on-premise, a straightforward deployment feature."
"There is a mismatch between the number of features they are offering and the device capacity on how much it can handle."
"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."
"The solution should improve finding false positives and false negatives. There are a lot of false positives."
"FortiADC is complex to configure so the interface should be improved."
"I think it would be helpful if Fortinet put more video examples on their cookbook site."
"The user interface could be more friendly and CLI could be more like that of Fortigate."
"Fortinet FortiADC should include an advanced-level SD-WAN."
"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."
 

Pricing and Cost Advice

Information not available
"The cost that they have with AWS are almost prohibitive. I'm being forced to use F5 WAF. I would not simply use it based on cost. I agree that they have some great features, but for me, cost is key in terms of AWS."
"Purchasing through the AWS Marketplace was very simple. The main reason that we went this way was the simplicity of buying it there. It is maintained and upgraded for us, and this makes it easy to stay current."
"The solution is quite expensive if we compare it with the competition."
"It is the best solution, but that comes with an increased price."
"The solution is more expensive than one of its competitors."
"Take a look at the modules that you are going to use. Look into the best bundles for them."
"It could be priced a little less, especially on the virtual side. It gets a bit expensive, but you get what you pay."
"If your IT budget is good, go for it."
"The solution could be more cost-effective."
"I rate Fortinet FortiADC's pricing one out of ten. It is fixed."
"Our basic license excludes features such as antivirus and IDS. Due to license limitations, some functionalities are not configured."
"I believe the price is good. It's fair. There are no extra costs."
"They offer a perpetual license."
"The price is competitive"
"The product has affordable pricing."
"Compared to F5, FortiADC pricing is better."
