Cisco Adaptive Security Appliance (ASA) software is the core OS for the ASA suite. It provides firewall functionality, as well as integration with context-specific Cisco security modules. It is scaled for enterprise-level traffic and connections.
We have quite a few visitors to our campus and we don't want to have a set PSK for the wireless so we have configured a guest network where visitors can create an account and gain access to the internet and we don't have to "manage" it since the accounts will expire after a certain time. We have RF scanners in our warehouses and we want them to be allowed on the network and be put into its own VLAN. ClearPass can do this flawlessly by keying off of the MAC address when it comes online and putting it into the correct VLAN. This makes it so we don't have to add each device individually to the system. The only time ClearPass would not be appropriate is in a small deployment where the cost to value wouldn't make sense.
Cisco ASA's are great for internal network connected access between a firewall and the central management server. And, for complex networks where high security requirements with overly strict compliance are necessary. For networks with limited connectivity to the core or for poor network connectivity these are not the best solution. There are other more stand-alone firewall's that do this better. These firewall's are a little more complex to set up to start with so significant knowledge of these devices is required to set them up and ensure they are best practice installed.
To be honest there has been now great products out in the market compared to Cisco ASA. I beleieve Cisco has to do a lot of improvement in this area. The other defeiniete factors is the cost when it comes to renewals which is always a premium on Cisco products
Aruba Clearpass is straight forward in terms of day to day use for monitoring and basic user connectivity issues. The system is very robust on the back end, therefore some larger configuration changes may not be the most intuitive. System upgrades and license management are not the most intuitive either.
I generally have not noticed the outages, however since it's a machine it can malfunction, we need to implement the firewall infrastructure in such a way that it is highly available with device failure, region failure etc. Else any solution will be having the issues if they are not build with resiliency.
We had some issues with ClearPass integration with AirGroup on Aruba Controller Clusters. Basically, it was tough to get coordinated between the controller support and the ClearPass support.
The support is usually very good and gets back to you very quickly. However I had some instances of when two engineers will give me wildly different answers to what I thought was a simple question. Overall however I do rate the support highly and they are generally always very good.
It was quite a good one, how ever requires an expertise to deploy hence the SMB segment would be finding it difficult to implement this product. The one good reason is that there are lot of ASA certified engineers in compared to the other certified engineers. Hence this resembles positively on the deployment as you have quite a lot of experienced engineer on your deployment
From my experience, ClearPass has been the best NAC server of all I've seen. Even though configuration is somewhat hard and it's hard to get training, once you learn how to configure it it works very well. The policies are very granular and scalable and the interface is a well-done web GUI that does not need any extra plugins installed, as some of Cisco's product require. There are many more options than with FortiNAC, and many more integration options. Also, troubleshooting and logging is good.
We were using [pfSense] before in our environment but we regularly facing difficulties over it due to software bugs & downtime. After implementing Cisco ASA, it resolved our availability issue & provides us a reliable solution with the best security features & easy to understand GUI.
