Quotes From Members

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

Pros
"I like the way Firepower presents the data. It gives you two classifications for the evidence, something based on the priority of the evidence and another classification based on the impact of the evidence in your environment. This makes it very easy to spot the evidence that is most impactful to my environment. Instead of having to go through all the evidence based on that priority, I can focus on the evidence that has the most impact on my environment.""The most valuable feature of the Firepower solution is FireSIGHT, which can be easily managed and is user-friendly.""Once you add Firepower onto to it and you start enabling some of its features, you get some IDS/IPS involved with it and you can even do web filtering.""The most valuable features of Cisco firewalls are the IPS and IDS items. We find them very helpful. Those are the biggest things because we have some odd, custom-made products in our environment. What we've found through their IPS and IDS is that their vulnerability engines have caught things that are near-Zero-day items, inside of our network.""The IPS, as well as the malware features, are the two things that we use the most and they're very valuable.""The protection and security features, like URL filtering, the inspection, and the IPS feature, are also very valuable for us. We don't have IT staff at most of the sites so for us it's important to have a robust firewall at those sites""We can easily track unauthorized users and see where traffic is going.""With the FMC and the FirePOWERs, the ability to quickly replace a piece of hardware without having to have a network outage is useful. Also, the ability to replace a piece of equipment and deploy the config that the previous piece of equipment had is pretty useful."

"We have expanded the wireless access point and switches using Fortinet FortiOS.""The fact that is it has a UTM, a Unified Threat Management feature is the most valuable aspect for us. It's an all in one product. It's like our one-stop-shop to the internet.""The most valuable features are the intrusion prevention system and the anti-virus.""For my organization, it has become much easier to scan the firewalls because the solution is more user-friendly than competitors.""The interface is easy to understand, so when there are threats you get alerts. It's quite intuitive, but if you are ever confused they have instructional videos. For example, if you don't understand a graph there's a link to a video that explains what the graph means. It makes it very user-friendly.""I like its configuration and the various functions it offers.""All of the features in this solution are effective and efficient.""The technical support is very good and the assistance they gave was very good."

"We can open a new VPN connection easily. It's much easier than with Fortinet in our experience.""I find the solution to be user-friendly. It has a lot of reports and easy settings.""The feature I find most valuable, is that the program helped me to realize all the requested functionality that was needed.""The initial setup is easy. It only takes 15-30 minutes to deploy.""The graphic user interface is very good and it is user-friendly which makes the product easy-to-use.""The solution is good for a basic firewall for a small business or for home use.""The interface and the dashboard are the most valuable features of this solution.""The most valuable features in OPNsense are reporting and visibility."

Cons
"Also, they have a Firepower source file that I can work on the ASA device and on Firepower devices. A problem here lies in the way that you manage these devices. Some devices do not support the FMC, and some devices have to be managed through ASDM, and others have to be managed through FMC.""I would like to see the inclusion of more advanced antivirus features in the next release of this solution.""In Firepower, there is an ability to search and dig into a search, which is nice. However, I'm not a super fan of the way it scrolls. If you want to look at something live, it's a lot different. You're almost waiting. With the ASDM, where it just flows, you can really see it. The second someone clicks something or does something, you'll see it. The refresh rate on the events in Firepower is not as smooth.""The worst part of the entire solution, and this is kind of trivial at times, is that management of the solution is difficult. You manage FireSIGHT through an internet browser. I've had Cisco tell me to manage it through Firefox because that's how they develop it. The problem is, depending on the page you're on, they don't function in the same way. The pages can be very buggy, or you can't resize columns in this one, or you can't do certain things in that one. It causes a headache in managing it.""For the new line of FTDs, the performance could be improved. We sometimes have issues with the 41 series, depending what we activate. If we activate too many intrusion policies, it affects the CPU.""The user interface for the Firepower management console is a little bit different from traditional Cisco management tools. If you look at products we already use, like Cisco Prime or other products that are cloud-based, they have a more modern user interface for managing the products. For Firepower, the user interface is not very user-friendly. It's a little bit confusing sometimes.""We would like to see improvement in recovery. If there is an issue that forces us to do recovery, we have to restart or reboot. In addition, sometimes we have downtime during the maintenance windows. If Cisco could enhance this, so that upgrades would not necessarily require downtime, that would be helpful.""We had an event recently where we had inbound traffic for SIP and we experienced an attack against our SIP endpoint, such that they were able to successfully make calls out... Both CTR, which is gathering data from multiple solutions that the vendor provides, as well as the FMC events connection, did not show any of those connections because there was not a NAT inbound which said either allow it or deny it."

"The additional features I would like to see included in the next release is better troubleshooting and reporting.""The complexity of the VPNs should be improved.""I would like to see smaller and more frequent updates.""The signature discs, compared to Palo Alto, aren't as good. It takes more time to get the signature updates.""The solution is good, but they have poor marketing in Nigeria. They need to market their product better.""For me, it is important to be able to block VPN applications, like Facebook, so I would like to see that included in the next release. With this version, if you want to block or allow a site, you now have to drag all the domains related to this site.""The GUI could be improved to make it more usable, easier to administer, and easier to configure.""In the future I would like to see more user-friendly dashboards and a drop in the price."

"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server.""On the customer-side, because I'm a small business, I need a cheaper or free solution option.""The ability to set the VPN IP address would be a welcome addition.""The solution would not be suitable for anything large-scale.""There should be more technical documentation.""There are issues with stability and reliability.""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.""I would like to see better SD-WAN performance."

Pricing and Cost Advice
"The price of this solution is not good or bad.""The Firepower series of appliances is not cheap. I just got a quote recently for six firewalls that was in the range of over half-a-million dollars. That's what could push us to look to other vendors...""Our subscription costs, just for the firewalls, is between $400,000 and $500,000 a year.""Cisco's pricing is high, at times, for what they provide.""The one-time cost is affordable, but the maintenance cost and the Smart Net costs need to be reduced. They're too high.""We normally license on a yearly basis. The hardware procurement cost should be considered. If you're virtual maybe that cost is eradicated and just the licensing cost is applied. If you have hardware the cost must be covered by you. All the shipping charges will be paid by you also. I don't thing there are any other hidden charges though.""Cisco pricing is premium. However, they gave us a 50 to 60 percent discount.""There are additional implementation and validation costs."

"The program is expensive.""We pay an annual license fee. It is rather expensive so I would like to perhaps see a drop in price in the future.""Be sure to choose a licensing plan that leaves a little headroom so performance is not an issue.""We pay $100,000. That covers the cost of the hardware that we run the VN's on. That also includes any SGNA costs for the internal support tech.""Pricing depends on implementation and licensing choices and is usually not a practical budget choice for small businesses.""The support contracts are usually about $100 - $200 a device.""The software costs roughly half what the hardware costs. Overall, the product is expensive."

"We are not paying any licensing fees. OPNsense is completely free for us.""It costs about $1000.""There are no licensing costs for OPNsence.""OPNsense is open source software so at this time it is free for us to use.""OPNsense is a well known open-source tool.""It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source.""OPNsense is an open-source solution and it is free to use.""The solution is not expensive."
