Reliable patch management, high uptime, and incredible knowledge base

In terms of security, it does a lot of things that most people still turn off. SELinux is turned on by default. They have pretty good firewall rules in their defaults. The audit rules always take tweaking, but, overall, it comes out of the box not too bad. I used to write scripts to harden them from there. There are multiple ways to provision and patch. You have everything from local repositories to doing it by hand. Their knowledge base is incredible. There is so much information out there. It has never taken me longer than 30 minutes to find an answer to anything, even very tough ones. One company I worked for was a security company, and we did a lot of patching on everything. It was designed around security and email hosting, and uptime was pretty much whatever we wanted it to be. I have had a couple of times when the uptime was bad, but it was caused by a third-party solution. In fact, the Norton antivirus was definitely the worst. Red Hat had nothing to do with it.

Quotes from Members

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

Pros

"Flatcar's support is good. The version I am using is stable and allows us to make needed changes."

"By implementing Red Hat Enterprise Linux, we wanted to solve some of the reboot problems of Windows. Every patch on Windows affected our applications because the system had to be rebooted. Red Hat Enterprise Linux has improved the uptime of the applications."

"Red Hat Enterprise Linux is lightweight and can be run on almost anything."

"I would like to say Red Hat Enterprise Linux (RHEL) is much more efficient than Windows, and my employees love the Linux command line."

"We are able to have a Linux system that is open-source and that allows us to do domain trust IBM and all that fun stuff. We have a good solid enterprise Linux."

"The enterprise aspect of it is valuable. There is security patching, security scanning, and compliance. There are all kinds of features around managing and keeping it up-to-date and secure. Everything is in a box for us from Red Hat which makes it very easy to manage them."

"Red Hat is open source, so what we get with Red Hat Enterprise Linux is valuable support that is not included in the free version."

"Automation makes compliance a lot easier."

"Red Hat Insights is valuable. There is patch and vulnerability management."

Cons

"The development teams could sharpen their skills. They should offer applications on the net."

"For phone support, we had to buy a license for all our servers, and it was a bit pricey for us."

"The numerous links to different pages disrupt the flow of information and make it difficult to maintain focus."

"Nowadays, delays are common with their support, and it often takes time to get assistance from experienced engineers."

"Integrating certificates from third-party clients into Red Hat Enterprise Linux can be challenging due to the operating system's stringent security policies."

"I would like Insight to include some features from OpenSCAP, which they offer for compliance services. I played with it a little bit, but haven't gotten the updated setup to get that. It creates excellent documentation."

"We have had issues with the identification of new volumes when you add new disks or storage."

"The implementation and limitations of SELinux should be re-evaluated."

"RHEL has experienced a change in approach after being acquired by IBM, and the company has shifted away from open-source principles."

Pricing and Cost Advice

Information not available

"From a management point of view, it's quite good, but everyone is complaining that it's more expensive than the other operating systems."

"The pricing and licensing are a bit higher for Red Hat Enterprise because we're able to get 70% of its features with the CentOS version. For the 30% of features that Red Hat provides, I think they need to reduce the licensing fee."

"Red Hat Linux is inexpensive. Linux solutions are generally inexpensive."

"Red Hat Enterprise Linux is only affordable for large organizations."

"It is expensive. Everything is. I was happy to get a three-year Red Hat Enterprise Linux contract for our initial rollout."

"The licensing makes perfect sense for the amount of stuff you get with the operating system."

"Red Hat Enterprise Linux has a yearly subscription cost for the licensing that includes maintenance and support."

"We can always ask for Red Hat Enterprise Linux to be less expensive but when we compare it to other options, there are savings in the long run."
