The Cisco Firepower 4100 Series’ 1-rack-unit size is presented by the vendodr as ideal at the Internet edge and in high-performance environments. They further state that it shows what’s happening on your network, detects attacks earlier so you can act faster, and reduces management complexity.
In any role where you need raw server power, CentOS Linux is extremely well suited. It is extremely stable, and in my experience, probably the most stable of the Linux distros available. It has a very wide base of support from 3rd party sources for additional functionality that do not come already in the CentOS Linux distribution itself. It is not as appropriate for situations that are customer facing or end user facing. For those, I recommend Ubuntu Linux. But for everything server & compute related, I recommend CentOS Linux.
When we are asked by local partners which security equipment we use we always recommend our Cisco security products. The Firepower firewall is no exception and we can easily recommend this to others who need a fast, secure, and well built system that integrates well with all your existing hardware and software.
The failover process is clunky. When out Fortigate firewalls failed over, we lost 1 ping. When our Firepowers failover, whether it is on purpose or not, we experience a 2.5 minute complete outage.
Cisco could stand to improve their support documentation. I have found it difficult to find good directions for configuring these, especially when it comes to NAT and IPSEC tunnels.
In general, the Cisco Firepower 4100 Series works well, great performance, support a high volume of traffic, configuration, users, the device is powerful and once you have something configured you can be sure that it will rarely fail but for day to day troubleshooting or modifications needed can be a little complicated due to you have to deploy every change you make in the device and is not as fast as other devices, in general a deploy takes 5 minutes.
Again, written documentation is excellent, even on the older versions. The support community is the best. It is comprehensive and I would say that it global because it transcends national boundaries. Also, you find all types of people using CentOS to do all sorts of things so you are bound to find someone to talk to if there are problems.
CentOS is based on RHEL, so it really came down to the costs when making the selection between our options. RHEL offered more support and features, but nothing that we specifically needed. CentOS is fully customizable, something Windows Server was also lacking in many ways. The stability and speed was unmatched in comparison to Windows, and we were not utilizing any Windows-specific software to require us to use the Microsoft alternative. My years of experience have also made it a breeze to set up and configure new CentOS instances, leading me to stay where I'm comfortable.
Cisco Firepower 4100 Series deployment is straightforward and easy to implement. It is also can support high availability and able to achieve redundancy. Besides, firmware upgrade is quite simple and the process does not take much effort as the upgrade will be automatically done by itself. Cisco Firepower 4100 Series is also very cost effective compared with other similar ranges of firewalls.
CentOS's support of RPM packages makes it very easy to replicate RHEL servers for development or testing in cheap / free environments
CentOS's minimalistic desktop environment requires additional tweaking / packages if you want to have a usable desktop environment with the niceties of other modern distributions. As a result, if developers want to use CentOS, they'll need to spend more time customizing it than other distros.
CentOS's easy customization from the command line lends itself well to our virtualization infrastructure where setup can be easily scripted to modify CentOS's configuration files.
