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.

Helped with the consolidation of tools and has a great dashboard

We have used different types of solutions. We had Cisco ASA for about 10 years, and then we switched to an on-site firewall to MX from Meraki, Cisco. For our cloud, we have Cisco Services Routers. The migration to the cloud has been a lot of work. Not all of our systems were compliant with being on the cloud so we had to work on some applications and delete some of them. For the old systems, we had to do extra work but for the newer systems, it was fine. The migration took around 18 months to migrate 99%. We had more than 2,000 on-prem firewall sites. Cisco helped with the migration to the cloud with the migration tool. Migrating MX was really easy and the tools helped us to migrate from the old ASA we had to the new MX. The cloud, firewalling, and CSR helped us from the data center on-premise approach to the cloud because at the time we didn't have a lot of experience with the cloud. It was easy to use the Cisco appliances in that space. I think that this solution has saved our IT staff time because of the ease of deployment. When I first started as a network engineer, it took a whole day to configure a firewall because of all the particularities you could potentially have at a site. I think that this solution saved our organization's time because security saves money because. At the end of the day, firewalls block threats. This solution helped with the consolidation of tools as we had all the observability tools in the solutions. Some 10 years ago we all had third-party solutions doing the observability. Now, we have the whole package and not only the firewall. We choose Cisco 10 or 20 years ago mostly because it was a market-leading solution. I also think it's because of MX's user-friendly solution that you can get on board easily. As far as CSA goes, I believe it's because you have a lot of features on the firewalls and it's the stability of course.

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

"The web filtering feature and the intrusion protection system are the most valuable. It is a resilient appliance. I never had an issue with it in terms of any security breaches."

"The most valuable feature of Fortinet FortiGate is load balancing. It can provide central management and VPNA. Additionally, it has enhanced our security environment."

"The main reason why I purchased the particular unit was that it had good reviews and what other people were saying as far as its completeness and its leading capabilities in terms of endpoint security was very good."

"It has very easy management and an amazing ETM configuration."

"It's very fast and easy to configure."

"Web filtering and two-factor authentication are great features."

"The most valuable feature is the bundled subscription, which is IPS, TV and web filtering."

"It's user-friendly and easy to operate."

More Fortinet FortiGate pros

"To be honest, all of the features that are provided, all the other vendor will also have. One feature we did find valuable was the CLI, it is more accurate. Additionally, I was happy with the customization, dashboards, access lists and interface."

"The stability of Cisco ASA is excellent compared to other products on the market. Because of our customer experience as an integrator company, our clients never report any performance problems. We have a good performance reputation with Cisco ASA."

"We moved from a legacy firewall to the ASA with FirePOWER, increasing our Internet Edge defense dramatically."

"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."

"Logging is great. It will show when it reaches its capacity before it is too late, unless you have bursts of traffic."

"The user interface, the UI, is excellent on the solution."

"The IPS, as well as the malware features, are the two things that we use the most and they're very valuable."

"Signature-based detection; user-defined signatures with regular expressions; integrated URL and content filtering; custom URL categories filtering."

More Cisco Secure Firewall pros

"Once you have Zscaler running you have access to configure it however you want."

"The solution offers good sandboxing."

"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."

"Zscaler Cloud Firewall understands the applications in the current generation and adapts to the present generation cloud applications."

"Zscaler provides effective protection against various cyber threats ensuring a safe environment"

"The visibility and log availability offered are highly valued for troubleshooting purposes, and this is a key factor driving customer interest in the firewall module."

"The solution is scalable."

"The initial setup is straightforward."

More Zscaler Cloud Firewall pros

Cons

"FortiOS is not simple."

"In terms of what could be improved, the SD-WAN is quite difficult, because if you install the new box, 15 is okay, but if you change from an old configuration, if there is already configuration and a policy when you change to SD-WAN, you must change the whole policy that you see in the interface."

"In the balance between links feature normally you can just choose one option to balance. It would be better for the solution to have more than one option, preferably three."

"It should have a better pricing plan. It is too expensive. It should also have a more granular view of the attack. I don't have FortiAnalyzer, and it is difficult for me to have a complete view when there is an attack on my server."

"The sniffing packets or packet captures, can be simplified and improved because it's a little confusing."

"Currently, FortiGate is providing SSL VPN. But they're missing some features that are available in Palo Alto's SSL VPN."

"I could not configure sFlow from the FortiGate graphical user interface. I realized that the sFlow configuration is available only from the CLI, and discovered that sFlow is not supported on virtual interfaces, such as VDOM links, IPsec, or GRE."

"The support team for Fortinet FortiGate needs to be more customer friendly."

More Fortinet FortiGate cons

"The performance should be improved."

"It can probably provide a holistic view of different appliances because many customers do not have only one brand, besides the traditional SNMP protocols, to cover all their devices. There are some specific requirements in terms of configurations or actions that sometimes have to be done in a very manual way because of the different versions or brands in a customer's infrastructure. It could also have some additional analytics capabilities. It has some very interesting ways to monitor the traffic and identify false positives from the architecture and the environment. It would be good if there is a way to patch with some other industry-specific solutions and synchronize some of the information, such as what other customers experience in their operations and probably share some additional information that could be leveraged or shared among the industry. Such information would be something interesting to see. It could have AI capabilities related to how the appliances could benefit from learning the current environment and different exposures."

"Cisco ASA Firewall could improve by adding more advanced features such as web filtering, which is available in the next-generation firewalls. However, the Cisco ASA Firewall I am using could be old and these features have been updated."

"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."

"One thing that Cisco could improve is the GUI. The graphic user interface should be more user-friendly."

"It doesn't have a proper GUI to do troubleshooting, so most people have to rely on the command line."

"The inclusion of an autofill feature would improve the ease of commands."

"We have encountered problems when implementing new signatures and new versions on our firewall. Sometimes, there is a short outage of our services, and we have not been able to understand what's going on. This is an area for improvement, and it would be good to have a way to monitor and understand why there is an outage."

More Cisco Secure Firewall cons

"Because it's on cloud, it doesn't allow application of extra settings."

"There are some areas it could improve when it comes to blocking, we have to block some things manually. For example, if we block a top-level domain we have seen that the new IPs come through, the IPs are not blocked. There should be some more granular way of doing it. My only request is if you're blocking something at a top level, the sub-level sub-domains and all those other IPs should be blocked too automatically."

"Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs."

"I don't have the visibility of a control dashboard or a network management system."

"Data Leak Prevention is only for web filtering and there is no protection for email."

"Zscaler Cloud Firewall should have a better understanding of all dynamic cloud applications."

"The product could improve its integration with some legacy systems."

"Pricing is a challenge."

Pricing and Cost Advice

"The price of Fortinet FortiGate is the lowest in the market."

"For our organization, the licensing costs are approximately $7,000 per year."

"It scales well if you know what to buy from a physical box standpoint. They seem to offer something for every level."

"The price for the Fortinet FortiGate is reasonable. Secure SD-WAN is free of charge. If you have their firewall, it's free of charge. It's very tempting."

"In terms of the market, it's not a cheap product, but it's cost-effective."

"We purchased a five-year bundle package, which worked out cheaper than competing solutions."

"For medium and enterprise organizations, FortiGate is more affordable."

"Fortinet Secure SD-WAN delivered the lowest total cost of ownership (TCO) per Mbps among all other vendors."

More Fortinet FortiGate pricing and cost advice

"We pay about $200 yearly and we have two firewalls."

"When we purchased the firewall, we had to take the security license for IPS, malware protection, and VPN. If we are using high availability, we have to take a license for that. We also have to pay for hardware support and technical support. Its licensing is on a yearly basis."

"Cost-wise, it's in the same range as its competitors. It's likely cheaper than Palo Alto. Cisco is affordable for a large organization of 500 to 1,000 users and above. You need a Cisco sales partner or engineer to explain to you the licensing aspects."

"Pricing for Cisco is expensive. There are additional costs for the licensing part, support, and even the hardware part. The device cost is very high. I would be very happy with an improvement on the price."

"All our requirements which we need performed by the firewall (e.g. VPN, URL white-listing, or IP based white-listing, etc.) have separate licenses and costs."

"I bought a license for three years and it was really affordable."

"Cisco is always expensive, but you get what you pay for. It is expensive for a reason. It is a good solution, and good solutions cost money."

"This is an expensive product, although when you buy this solution, you can do many things so it provides good value for the investment."

More Cisco Secure Firewall pricing and cost advice

"It comes at a significantly reduced cost while ensuring control and effectiveness."

"There are licensing costs, and I would not say that it's a cheap vendor."

"It is expensive for small businesses."

"Zscaler is priced too high compared to the cost of Fortinet."

"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing an eight out of ten."

"There are different subscription models available."

"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."
