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."

"The user interface and the ease of use are pretty good. Everything fits together so nicely.""The routing of the multiple internet physical routers I have is the most valuable feature of this solution. Instead of me physically unplugging a cable from one router to the server, if one connection goes down, it automatically switches for me. So I can have all three of them plugged in. If one goes down, it just picks up the other one automatically. There's no physical cable swapping.""The interface control manager where we can allocate LAN connections to certain VLANs is the most valuable feature. The other feature that's important for us is because obviously everything is remote with MyKerio, as long as the boat has an internet connection, we can log onto the Kerio and get statistics, as well as provide support.""We also like the security. We can control what sites users can go to and we can make sure that where they're going is appropriate and that it's work-related.""The initial setup is a breeze.""Kerio is a lot clearer to set up to do particular things, whereas when I do it on a Cisco or a FortiGate I have to go fight with it per week sometimes to do something I can do in 20 minutes on Kerio.""It is very comprehensive and simple. It has all the active protections. It's updated. We love that you can set how often it is updated so you can work what is right for you. A large company with a lot of bandwidth can update the virus definitions and security definitions hourly, if they want. A smaller site that's remote, where maybe updating the definitions will eat into the bandwidth, we can schedule those more to go later at night. It's very flexible and works for us in all types of situations. This is great because then we don't have to learn seven different products to be able to work with seven different scenarios.""The most valuable feature is the reliability of VPN capabilities. The VPN has been very reliable and secure. The security has been very good and the VPN connections are reliable in that they stay up. We don't have a lot of problems with downtime and that type of thing."

"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.""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.""The most valuable features are reporting, the Sensei plugin, and firewall capabilities."

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 one thing that did put me off of the solution was that, after they were taken over by GFI, the licensing and a few other items have gotten very complicated.""I would like it if the interface section had multiple failovers. Although I do have three connections, just in case our physical cables get disconnected, I can only set up one failover as a backup. So, if for some reason our fiber and our AFM went down together, I would have to have it search for our 4G modem. I'd love to have extra backups running.""It has a VPN back to our data center but I don't think it has increased the number of VPN clients extended to those outside our environment""The denial of service could also be improved. There recently was a big issue with denial of service attacks and it was a bit laborious.""When it comes to dealing with updates, there are often bugs on the solution. They should do a lot more testing before they release new versions.""The overall speed needs improvement. Internet connectivity speed needs to be improved somehow.""I would like to see a little improvement in their technical support when you have a problem. I may be a little jaded because I came from Kerio when we could call and get a person on the phone who worked on the product. Every tech had their own demo setup. They had instant messaging capability with the developers. If we found a problem, then we could get a result for it quickly. Now, the product seems to be 24 hours. They have also gone to the model that if you need quicker support, then they now charge you additional for the exact same level of support that they used to give. I am assuming it's the exact same level of support that they say it is. I'm not paying extra for it. That's the biggest flaw with the product.""One of the problems we do have causes problems with the VPN. The software slows the throughput down too much. You could have a one-gigabit connection from the internet, and it slows it down to the area of upload and download is extremely slow. There's too much content filtering at that point."

More Kerio Control Cons »

"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.""The solution could be more secure."

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."

More Cisco Firepower NGFW Firewall Pricing and Cost Advice »

"It is priced low enough for entry-level, but it has the power to grow with a company without them having to replace it.""The biggest advice that I could probably give people is when you buy the solution be prepared to either buy the unlimited license or buy more licenses than you think. Each user license gives you one employee and each a user gives you five devices. In the world nowadays where everybody has a cellphone, tablet, desktop, and laptop, that's four devices. You still get one more device per person. That covers your servers and back-ends.""It is a good fit for SMBs because of its maintainability. When you want to keep your costs low, then Kerio Control is a very good solution. It's not an expensive product that is well integrated. It has a complete set of features within it that make it a very strong product.""GFI has made a stupid decision regarding small office licensing. For offices where there are only three to five employees and had five years towards a five user product, they now force these customers to a 10-year user license. I really don't understand it. It's a stupid decision for the small offices who want a good solution for security because they'll probably decide to go to another product. Why should they buy something that they don't use?""The fixed model of users and devices is a bit of a problem for us. We want to be able to expand it fast and not have to contact our supplier first to get a license... If they had a larger fixed price with unlimited users or devices, that would help. Now, it's five users each time. A pack of 100 or 200 users for a certain price would make it more dynamic and user-scalable.""The yearly maintenance fee is a bit high for the Kerio Control Boxes. The end of life for the devices is kind of short. It seems like they're making you upgrade within a short period of time. They should at least allow five years, but it seems like they are changing their end of life to be shorter to generate revenue.""It gives us a lot. It does prove to be a very robust product for the cost.""I think it is a bit on the pricey side, but it's okay. I've got 50 licenses which I think is $250 a year or something like that."

"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."
