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 feature of this solution is AMP (Advanced Malware Protection), as this is really needed to protect against cyber threats.I like the Cisco ASDM (Adaptive Security Device Manager), which is the configuration interface for the Cisco firewall.The technical team is always available when we have problems.

They have a system which can collect all of the performance data, and they show it on a very nice dashboard.

The scanning feature is impressive, because they do not introduce a big latency to the traffic.Zscaler Web Security protects our users in remote locations from internet threats - even if they are not connected to our network.The most valuable feature is bandwidth control.The solution offers a distributed organization to master and to control all of the endpoints.The best thing about Zscaler Internet Access is the website filtering. In the UAE it's quite an important feature because most of the malware comes through the SQL injection and through downloads from websites. Zscaler helps protect against that.The initial setup was straightforward. The biggest thing for us was to build our own policies. The deployment itself was only a few hours.All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none.Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere.

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.I have found that Cisco reporting capabilities are not as rich as other products, so the reporting could be improved.The Sandbox and the Web Censoring in this solution need to be improved.It will be nice if they had what you traditionally would use a web application scanner for. If the solution could take a deeper look into HTTP and HTTPS traffic, that would be nice.

It would be good to have some deeper security measures implemented. The solution should go even deeper on the firewall level.

I would like to see the ability to choose a pool of IPs for my company, set up rules based on them, and know that those IPs are not used by other companies.Another thing that I would like to see is if Zscaler could have a separate product for direct access. I looked at a private access solution, but I understand there's a separate product that isn't integrated with this.It also needs better integration with other applications as well. There are some restrictions.Zscaler should provide adjacent services, which would be complementary to their current offering that could to be more pragmatic for a customer. For example, if you take Akamai, you get multiple sets of services, all depending on the customer and the strategy and the complexity and the problems. In some areas, they are more varied in terms of coverage.In terms of usage, here in the GCC, it's still growing a growing market, so the combination of DLP, data leak prevention, to a certain extent is fine. But what it requires is user-based access or role-based access. The solution needs to grow into that, which definitely takes time. There's not an easy way to integrate it, when you have a cloud-based solution.In every cloud service in the world, you have multiple upstream internet providers to create diversity so that if one of your providers fails, your network just continues. In South Africa, there is only one upstream provider, and that's not right. That that's a problem.It needs better integration with other applications. It takes a fair amount of regular activity to apply the by-passes because it is very strict in its restrictions and frequently you have to go in and open things up to allow the workforce to work.The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market.

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.We are in the process of renewing our three-year license, which costs approximately $24,000 USD for the thirty-six months.The pricing for Cisco products is higher than others, but Cisco is a very good, strong, and stable technology.The program is very expensive.The cost of this solution is high.Some of our customers would be more likely to standardize on Cisco equipment if the cost was lower because a lot of people install cheap equipment.

Our monthly fee is around R3000.Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee.The pricing is an issue. It is expensive compared to other firewalls on the market.​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​
