Efficient, user-friendly, and affordable
In the past, NSS Labs was utilized to test files and verify the numbers and datasheets. It would be beneficial to have an organization or testing lab that can verify the numbers in our datasheets since changes are frequently made, which can be inconvenient for review. For instance, when comparing different competitors such as Forcepoint, Palo Alto, and Check Point, the throughput or numbers in the datasheet may be lower than the actual numbers. Conversely, Fortinet typically reports very high numbers, but they cannot be replicated in the real world. Therefore, it would be advantageous for them to partner with a neutral testing organization such as NSS Labs to validate these numbers, thus providing more credibility and comfort to everyone regarding the accuracy of the datasheets. For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial. This tool shows a lot of promise and is very good. Making it free would help many companies deliver their products in a more efficient and integrated way. It would also be more valuable to include the tool with the firewall package or license instead of having to pay extra for it. Paying extra puts more pressure on small companies to deliver the firewall and complete the configuration, especially if they have hundreds or thousands of policies. It's very painful to move through these policies line by line. The stability has room for improvement. When it comes to Secure SD-WAN, everything is fine. They are going the right way. SD-WAN is very promising. They can provide the SD-WAN solution separately, but they will not take this approach because even the smallest firewall can support the features, so there is no need to have a separate service or appliance. They are following the right steps, and there is nothing to be improved. Feature-wise, I'm really satisfied with the new release, and the features they have added. For now, it's fine.

Enhances security with precise access control but has integration challenges
Overall, I would rate the product six out of ten. Because of the support and cost, I moved away from Cisco, but otherwise, it is a good product. Recommendation depends on the requirement. If lacking a proper team and being dependent on the OEM and partner, Cisco is not suitable. However, if the team is qualified with Cisco-certified people and the requirement is a big network, it can be considered. In today's hybrid work world, having an expanded gateway is more typical than having a single one. Thus, Cisco is unlikely to be recommended for a hybrid requirement unless in-house skills align. Otherwise, depending on partners and Cisco, it can be a risk. I rate the overall solution six out of ten.
Bhaskar Rao - PeerSpot reviewer
Though it helps deal with web traffic or any malicious traffic, it needs to work on its DC performance issues
The product's initial setup phase is moderate in level, so it is neither very complex nor very easy. For the deployment, my company first needs to gather all the requirements of the users and the domain names and consider how many users there are in the company. In the implementation and planning part, my company needs to consider what kind of policies we will create while ensuring that the policies are created based on the requirements of the users. There is a need to segregate the users' requirements since there are separate departments in the company, like the HR department, sales department, IT department, and manufacturing department, so that our company can create policies depending on their requirements. On-site, if you want a GRE tunnel, our company can handle GRE tunnel traffic routing and Zscaler Cloud Firewall, after which Zscaler will take action based on the policies created by our organization. For the deployments and maintenance, a team of five members consisting of two managers and three engineers is required.

Quotes from Members

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

Pros

"FortiGate's web and URL filtering are unlike any other firewall I've used. The functionality of URL filtering in those solutions is problematic because everything is encrypted, and firewalls can't break that encryption protocol. Fortinet has an SSL proxy, so the encryption is done before the packet ever leaves the FortiGate. The URL filter is definitely one of the most helpful features."
"Easy to use support and licensing portal as well as activation process."
"Consolidated our network environment at all locations, but mainly at our datacenter."
"The IPsec tunnels are very easily created, and quite interoperable with devices from other vendors."
"FortiGate is on the cheaper end, and it offers good value."
"The features that we have found most valuable are the SSL VPN and the User Portal."
"FortiOS is quite good in my experience with Fortinet FortiGate, and it works very effectively and is stable for companies. The customers have given feedback that FortiOS has been very stable for a long time."
"I'm pretty happy with its reliability. It is also very scalable."
"AnyConnect has been very helpful, along with the ability to use LDAP for authentication."
"The solution is excellent for enterprise-level networks."
"The configuration was kind of straightforward from the command line and also from the ASDM. It was very easy to manage by using their software in Java."
"Cisco Secure Firewall is a good solution. In some ways, it is a reactive solution and we have it sitting in a whitelist mode rather than a blacklist mode. It seems to work fairly well for us."
"It's got the capabilities of amassing a lot of throughput with remote access and VPNs."
"We find all of its features very useful. Its main features are policies and access lists. We use both of them, and we also use routing."
"The product is quite robust and durable."
"It brings us the ability to work from anywhere and has allowed us to work remotely without having to incur a lot of other costs. If we didn't have this type of solution, since we have so many on-prem services that are required, we would have likely lost money and been unable to deliver. We have a video services team who helped build the content for our sporting events. When you are watching a Leaf game and those swipes come by as well as the clips and things, those are all generated in-house. Without the ability to access our on-premise resources, we would have been dead in the water. So, the return on that is pretty impressive."
"It provides in-depth visibility into your network, ensuring that traffic flowing into your organization, be it from offices or individual users, is effectively filtered and secured through multiple layers of protection."
"Since it is really customizable, I can use it and avoid enabling access to the full network."
"The scalability is okay. We have around 2200 people using this solution."
"If malicious traffic attacks our on-premises servers, then it gets blocked by Zscaler Cloud Firewall."
"Zscaler provides effective protection against various cyber threats ensuring a safe environment"
"Includes advanced tech protection."
"Most of the features that Zscaler has to offer, we will deploy."
"I like the ease of deployment and its flexibility. We don't need to deal with license, quotes, procurement, delivery, and installation. Everything is software-based, and it's very easy to operate."
 

Cons

"Technical support for this solution can be improved."
"It is very expensive, and their support is not very good. I hope that their technical support will be better in the future."
"Sometimes you do need to know some CLI commands, so it's a bit harder for technicians or new people that don't know it."
"There can be more security in hybrid implementations. When a customer has a hybrid environment where some parts are in the cloud, we need a consistent security solution for such scenarios."
"The pricing could be reduced or include the first year warranty."
"Some of the features in the graphical user interface do not work, which requires that we used the command-line-interface."
"Fortinet FortiGate needs to improve to be on par with its competitors, such as Palo Alto and Sophos. They are the market leaders. Fortinet FortiGate needs to improve its capabilities. However, we are happy with Fortinet FortiGate."
"Though the tool's GUI is user-friendly, it can be considered as an area with certain shortcomings where improvements are required."
"Cisco makes horrible UIs, so the interface is something that should be improved."
"Managing various product integrations, such as Umbrella, is challenging."
"The intelligence has room for improvement. There are some hackers that we haven't seen before and its ability to detect those types of attacks needs to be improved."
"When we first got it, we were doing individual configuring. Now, there is a way to manage from one location."
"In the future, I would like to be able to use an IP phone over a VPN connection."
"With the new FTD, there is a little bit of a learning curve."
"The GUI interface could be improved when compared to other solutions."
"One big pain point I have is the ASDM interface because it's Java, and sometimes, it's a bit buggy and has low performance. That's something that probably won't be improved because of backward compatibility."
"It would be better if they improved their policy, package visibility, and flexibility while we're creating rules for inspection. It could also be cheaper or more things could be included in the basic package. In the next release, I would like better coverage in the Asia Pacific region and better quality of service."
"Apart from the issues associated with the product in areas like the DC performance issues and DC failover, Zscaler Cloud Firewall's IP should not have a proxy IP."
"If I can get rid of Jetscaler, I will use Twingate for sure."
"Zscaler Cloud Firewall should have a better understanding of all dynamic cloud applications."
"Data Leak Prevention is only for web filtering and there is no protection for email."
"The product could improve its integration with some legacy systems."
"Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs."
"When it comes to customer support, there is room for improvement in Zscaler's service."
 

Pricing and Cost Advice

"The price of FortiGate is good."
"For the price, I'd rate it a ten because it's very cost-effective."
"The license is yearly. We pay for the top end. It's called 360."
"At the time we bought them, I was satisfied with their pricing; I don't know how the new pricing will be."
"Easy to understand licensing requirements."
"Fortinet FortiGate as a less expensive solution than Palo Alto."
"The price of FortiGate is average and I would say that based on the top five products available on the market, it is in the affordable range."
"I give the pricing a nine out of ten."
"Cisco is not for a small mom-and-pop shop because of the cost, but if you're in a regulated industry where a breach could cost you a million dollars, it's a bargain."
"Always plan ahead for three years. In other words, do not buy a firewall on what your needs are today, but try to predict where you will be three years from now in terms of bandwidth, security requirements, and changes in organizational design."
"It's pretty competitive. If they could make it cheaper, it would be great. You always want cheaper, but relative to the performance capabilities of the firewall and relative to what you get, it's fair. It's not the cheapest in the world, but you get an excellent product for that price."
"It is more expensive than the other solutions."
"ASA pricing seems high compared to other firewalls, such as the Sophos XG models."
"The pricing is too high and the licensing is too confusing."
"The licensing package is good, but the licensing fee should be decreased."
"Cisco's pricing is high, at times, for what they provide."
"There are different subscription models available."
"There is an annual license required for the use of the Zscaler Cloud Firewall."
"There are licensing costs, and I would not say that it's a cheap vendor."
"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."
"The product is a bit expensive compared to the solutions offered by its competitors, like Palo Alto. There is a need to make yearly payments towards the license in charges associated with the product."
"It is not the most budget-friendly solution, but it's important to consider its overall value."
"It is expensive for small businesses."
"It comes at a significantly reduced cost while ensuring control and effectiveness."

Cisco ASA vs. Palo Alto Networks
Cisco ASA vs. Palo Alto: Management Goodies You often have comparisons of both firewalls concerning security components. Of course, a firewall must block attacks, scan for viruses, build VPNs, etc. However, in this post I am discussing the advantages and disadvantages from both vendors concerning…
