pfSense is a firewall and load management product available through the open source pfSense Community Edition, as well as a the licensed edition, pfSense Plus (formerly known as pfSense Enterprise). The solution provides combined firewall, VPN, and router functionality, and can be deployed through the cloud (AWS or Azure), or on-premises with a Netgate appliance. It as scalable capacities, with functionality for SMBs. As a firewall, pfSense offers Stateful packet inspection, concurrent…
We evaluated other Cisco security devices and other vendors, but chose the Cisco ASA due to it's price point and compatibility. While Fortinet and Palo Alto are leaders in the field, we found that for the price, the features we needed were fully satisfied by the ASA. We …
Cisco ASAs are a world apart from SonicWall's, and even more so pfSense. Sonicwall's are okay for SOHO purposes; they're not expensive, but they're not as robust either. They often choke bandwidth because of CPU limitations. pfSense is a Linux-based firewall, and it does the …
[Cisco] ASA is far better than pfSense[.] pfSense is a very complicated firewall and if you need any help documentation is not easily available. Cisco ASA configuration via CLI is [the] very best and fast for configuration[.]
I am a freelancer consultant so I use lots of firewalls. I recommended Cisco ASA to my client and asked him to replace pfSense because pfSense is not easy firewall. Options are very different and commands are very tricky. Lots of options are not available. But ASA is better …
pfSense is a nice firewall but it is minimal in features. The main advantage of Cisco ASA is routing, VPN, and NAT, and pfSense is providing these features but they are only basic. Cisco ASA provides lots of options in NAT but pfSense provides basic NAT features, so according …
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 …
We were using pfSense before in our environment but we were facing continuous issues in configuration management & policy-based management. After the implementation of Cisco ASA, it has resolved both the previous problems & also provided us a reliable solution with High …
We were using pfSense in our environment before for remote VPN but we were facing continuous configuration misbehave issues. After using Cisco ASA is have resolved our remote VPN & security issues. It has also GUI Based control access so that we can easily check & manage things …
We were using pfsence before [the] Cisco ASA firewall and we were not happy with pfSense features. Lots of features are missing in pfSence so we decided to install the [Cisco] ASA 5525 and we are very happy with the features. There are lots of options in nat and you can easy to …
We were using the pfSense but we were not happy with the services. We were facing lots of downtime and bugs during the production hours. That's why we selected Cisco ASA. It is a really very good firewall and we haveb't faced any downtime in the last 3 years.
I don't thin[k] any basic firewall in this budget is better then Cisco ASA. ASA provides you lots of option[s] in vpn, nat and this is very easy to configure. This is not complected firewall. Beginner network also can configure this and handle this. No downtime is main …
Above all, the robustness and quality of the components, the support and the rapid resolution of warranty issues. Cisco is a serious company and demonstrates this by making the processes with the client as easy as possible.
pfSense is a lot cheaper and has higher firewall throughput per dollar than "enterprise" network appliances. It's also significantly easier to configure and learn. It may not have some of the "enterprise" features or the support level that someone like Cisco has, but for small …
It's an open source solution can support from 50 to 700 user without sweating and with the half of the standard bundle investment that will take to deploy a FortiGate UTM, or a Cisco ASA, also a Sophos UTM that are quite remarkable units but to pFSense saves you money and will …
I've used a number of routers like Cisco, Sonicwall, Juniper, Home based routers, etc. pfSense is like most routers but with the benefit of load balancing and multi-wan. Well many support multi-wan but load balancing is usually a separate device like an BIGiP F5 or Cisco CSS.
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.
Because pfSense is built around open source software, it is very convenient to be able to deploy in the event of hardware failure. We once had a client with a proprietary router that failed. While the router was under warranty, the expected time for the new router to arrive was about 2 weeks. We decided to implement pfSense for the client as a stop gap and ultimately ended up deploying the full enterprise appliance. Being able to get up and running using commodity hardware was a huge win for the client. We've also had a great amount of success deploying pfSense hardware at apartment complexes. The DNS resolver works great and we've had no issues handling multiple VLANs with various DHCP scopes on it. Finally, we've had clients that require having a failover cluster. Utilizing the built in CARP capabilities, we've been able to provide a very robust failover system that requires little maintenance and no downtime in the event of equipment failure.
Easy to use. Good user interface design! Easy to understand and easy to set up.
Lower hardware requirement. 3 years ago, we used an old PC to run it. Now, we have changed to a router device with Celeron CPU and 8GB RAM. It runs smoothly with a 1000G commercial broadband.
I did kind of mention a Con in the Pro section with OpenVPN.
When I create a config for an employee other employees are able to login to that config.
I could be doing something wrong when I am making it - I am not afraid to admit that as I am pretty new to all of this, but it seems like it builds a key and I would think the key would be unique in some way to each employee, but I could be wrong.
I actually do not have a lot of Con's for this software - I did not get to set this up on our work network so I am not sure of any downfalls when installing.
I installed this on my personal machine in a Hyper-V environment to get a feel for it before I started working on it at work and it seemed pretty smooth. I didn't run into any issues.
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
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.
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
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.
While you can get the performance out of other products, pfSense offers the unique ability to put other services on the same device. Products such as Untagle's NG Firewall and SonicWall's TZ series offer cost effective options for firewall and VPN services, having incoming load balancing and connection proxies on the same device as the firewall offers extremely easy configuration and day to day management of network services
Using pfSense has allowed us to build a professional network in our small office without needing a lot of proprietary hardware, saving thousands of dollars in IT infrastructure investment.
The cost for using pfSense is free, so it's a great option for those who don't have a large IT budget
pfSense utilizes all of the industry standard services to provide all of it's functionality, so support for service-level issues is readily available
Because of how much work has been put into pfSense to make it rock solid and reliable, we're able to support our network with minimal IT staffing, saving us thousands of dollars/year in personnel alone.
