Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The most valuable features of this solution are the integrations and IPS throughput.""One of the most valuable features is the AMP. It's very good and very reliable when it comes to malicious activities, websites, and viruses.""Another benefit has been user integration. We try to integrate our policies so that we can create policies based on active users. We can create policies based on who is accessing a resource instead of just IP addresses and ports.""One of the nice things about Firepower is that you can set it to discover the environment. If that is happening, then Firepower is learning about every device, software operating system, and application running inside or across your environment. Then, you can leverage the discovery intelligence to get Firepower to select the most appropriate intrusion prevention rules to use for your environment rather than picking one of the base policies that might have 50,000 IPS rules in it, which can put a lot of overhead on your firewall. If you choose the recommendations, as long as you update them regularly, you might be able to get your rule set down to only 1,000 or 1,500, which is a significant reduction in a base rule set. This means that the firewall will give you better performance because there are less rules being checked unnecessarily. That is really useful.""The solution offers very easy configurations.""The dashboard is the most important thing. It provides good visibility and makes management easy. Firepower also provides us with good application visibility and control.""The most valuable features of this solution are advanced malware protection, IPS, and IDS.""It is one of the fastest solutions, if not the fastest, in the security technology space. This gives us peace of mind knowing that as soon as a new attack comes online that we will be protected in short order. From that perspective, no one really comes close now to Firepower, which is hugely valuable to us from an upcoming new attack prevention perspective."

"It covers everything we need it to without looking to secondary solutions.""The solution is very user-friendly and easy to deal with.""We are able to filter a lot of traffic especially when a lot of the traffic is in layer 7.""One of the valuable features of the solution is its flexibility and it performs great.""Completely integrates branch offices with perimeter security.""The technical is excellent.""The hardware is pretty stable. It's also a very good product performance-wise. Initially, it wasn't mature like a firewall and there were other leaders, but now they have included almost all the features of next-generation security. Basically, it's a good product to work with.""Cisco Technical Assistance Center works on a follow-the-sun concept and gives real 24x7 customer support, which is a great advantage when you have a service contract with them."

More Cisco IOS Security Pros →

"The system in general is quite flexible.""I have found the solution has some great features overall, such as guest access capabilities, dashboards, and ease of use. There is plenty of documentation and support and it has the plugins that I needed.""The initial implementation process is simple.""The graphic user interface is very good and it is user-friendly which makes the product easy-to-use.""The most valuable features in OPNsense are reporting and visibility.""The most valuable features are reporting, the Sensei plugin, and firewall capabilities.""The interface and the dashboard are the most valuable features of this solution.""The VPN server feature is the most valuable. It is integrated with Radius and AAA for doing accounting and authentication. Insight view is also an important feature for me at this time. It allows me to assess our network traffic. I also like the firewall feature. The BSD kernel has a packet filter. It is one of the most solid frameworks for firewalls. Its user interface is one of the best interfaces I have used."

Cons
"The intelligence has room for improvement. There are some hackers that we haven't seen before and its ability to detect those types of attacks needs to be improved.""An area of improvement for this solution is the console visualization.""Deploying configurations takes longer than it should.""The initial setup was a bit complex. It wasn't a major challenge, but due to our requirements and network, it was not very straightforward but still easy enough.""The configuration in Firepower Management Center is very slow. Deployment takes two to three minutes. You spend a lot of time on modifications. Whereas, in FortiGate, you press a button, and it takes one second.""Implementations require the use of a console. It would help if the console was embedded.""Report generation is an area that should be improved.""The change-deployment time can always be improved. Even at 50 seconds, it's longer than some of its competitors. I would challenge Cisco to continue to improve in that area."

"I think they should bring back remote VPN for users.""The user interface needs to be improved.""With respect to user-friendliness, it is a command-line interface and those with such experience will get along just fine, whereas others may struggle.""The pricing is the only con for this product.""I would love it if it has a link-by-link feature, integration with Unified Threat Management (UTM), and load balancers. They haven't got any link-by-link feature right now, which can be a very attractive option. This link-by-link feature can also be made available for Cisco's UTM firewalls. The link-by-link feature is available in some of the other firewalls. Currently, integration with UTM is missing. Cisco IOS Security also doesn't have the load balancers and a few things that need to be done to get a good UTM firewall. Normally, other firewalls have UTM. As a next-generation firewall, it's good, but as a UTM, it has to do some work.""The company needs to make its solution more affordable to make it more accessible to larger markets. Otherwise, it's seen as an enterprise-level solution that small or medium-sized organizations can't afford and therefore they won't even look at it.""Signatures and other critical definitions need to be updated more frequently.""It would be ideal if the solution had more capacity."

More Cisco IOS Security Cons →

"I would like to see better SD-WAN performance.""The logging could improve in OPNsense.""The only thing that I would like to see improved is the Insight or the NetFlow analysis part. It would be good to have the possibility to dig down on the Insight platform. Right now, we can easily do only a few analyses. If this page becomes more powerful, it surely will be a well-adopted platform.""There are issues with stability and reliability.""While they do have paid options that actually gives better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet.""The interface needs to be simplified. It is not user-friendly.""There should be more technical documentation.""The solution would not be suitable for anything large-scale."
