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

Pros
For us, the most valuable features are the IPX and the Sourcefire Defense Center module. That gives us visibility into the traffic coming in and going out, and gives us the heads-up if there is a potential outbreak or potential malicious user who is trying to access the site. It also helps us see traffic generated by an end device trying to reach out to the world.The information coming from Talos does a good job... I like the fact that Cisco is working with them and getting the information from them and updating the firewall.The firepower sensors have been great; they do a good job of dropping unwanted traffic.Unfortunately in Cisco, only the hardware was good.The most important point is the detection engine which is now part of the next-generation firewalls and which is supported by Cisco Talos.The most valuable features are the flexibility and level of security that this solution provides.Integration with all the other Cisco tools is valuable.We moved from a legacy firewall to the ASA with FirePOWER, increasing our Internet Edge defense dramatically.

For business purposes, it's a very detailed solution, which is it's greatest benefit, as you can get almost any piece of information you need from the solution. It allows for admins to be able to troubleshoot pretty easily.A stable and solid solution for protection from external threats and for VPN connections.The best solutions for our company are those we have yet to implement so it will be even better in the future for us than it already is.The stability is good. Very simple. Upgrades are great.The feature I find most valuable is the Cisco VPN Interconnection.What I like about Cisco is the security zone. By default when you configure it, it gives you a security zone, which other firewalls don't have.We are using the Cisco AnyConnect for our end-user VPN with the ASA.The basic setup is fine. We're just one person. It's only when you want to do some more sophisticated setup like channeling and stuff like that that it's more complicated.

The initial setup is easy. It only takes 15-30 minutes to deploy.The feature I find most valuable, is that the program helped me to realize all the requested functionality that was needed.I find the solution to be user-friendly. It has a lot of reports and easy settings.We can open a new VPN connection easily. It's much easier than with Fortinet in our experience.

Cons
We were also not too thrilled when Cisco announced that in the upcoming new-gen ASA, iOS was not going to be supported, or if you install them, they will not be able to be managed through the Sourcefire. However, it seems like Cisco is moving away from the ASA iOS to the Sourcefire FireSIGHT firmware for the ASA. We haven't had a chance to test it out.Our latest experience with a code upgrade included a number of bugs and issues that we ran into. So more testing with their code, before it hits us, would help.The software was very buggy, to the point it had to be removed.In NGFW, Cisco should be aligned with the new technology and inspection intelligence because Cisco is far behind in this pipeline.Most users do not have awareness of this product's functionality and features. Cisco should do something to make them aware of them. That would be quite excellent and useful to organizations that are still using legacy data-center-security products.There was an error in the configuration, related to our uplink switches, that caused us to contact technical support, and it took a very long time to resolve the issue.With regards to stability, we had a critical bug come out during our evaluation... not good.The product would be improved if the GUI could be brought into the 21st Century.

I'm working on a slightly older version, but what it needs is a better alert management. It's pretty standard, but there's no real advanced features involved around it.It is not the newest, cutting-edge technologyThe user interface is too complex for people who are not trained to or certified to engage with the product. The interface should be easier to use.They really need support for deployment.They should allow customers to talk to them directly instead of having to go through the reseller.I wish the Cisco interface was not so granular. Check Point was easier to create specific rules than with ASAv.I would like to see them release a patch for ASAv with cross-platform FirePower integration.The user interface is old fashioned.

On the customer-side, because I'm a small business, I need a cheaper or free solution option.OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server.

Pricing and Cost Advice
Pricing varies on the model and the features we are using. It could be anywhere from $600 to $1000 to up to $7,000 per year, depending on what model and what feature sets are available to us.We used Check Point and the two are comparable. Cost was really what put us onto the ASAs... the price tag for Check Point was exorbitantly more than what it is for the ASA solution.Always consider what you might need to reduce your wasted time and invest it in other solutions.Watch out for hidden licensing and incredibly high annual maintenance costs.We paid about $7,000 for the Cisco firewall, plus another small Cisco router and the lead switch. It was under the combined license. It's a final agreement.The cost is a big factor for us. This is why we are using it only in our restricted area. They are very much higher than their competitors in the market.Licensing is expensive compared to other solutions.Pricing is high, but it is essentially a corporate decision.

It would be nice if pricing could do more to reflect the economy of the country where the product is being implemented.This solution might be expensive, but it is economical in the long run.With AnyConnect, it depends on your license. It depends on the number of concurrent users you want to connect.I bought a license for three years and it was really affordable.We are partners with Cisco. They are always one call away, which is good. They know how to keep their customers happy.With the Cisco ASA, you do get what you pay for. What would really be awesome is to see Cisco blow out a real cheap version where you can use the sandbox, but leave it step-wise and go to another product relatively easily, like getting you hooked on candy.Purchasing from the AWS Marketplace was easy. It was just point and click.It is pay-as-you-go, so it much cheaper than buying in the plants.
