A stable solution with an intuitive interface and quick customer service

I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Unified policies streamline network management but complex licensing requires attention

Phil Shiflett

Senior Manager, Network Engineering at TTi Power Equipment

Cisco Secure Firewall has some growth opportunities in terms of visibility and control capabilities regarding managing encrypted traffic. It has the ability to analyze encrypted traffic, and there is potential for more integration with APIs and AI to enhance these capabilities. Cisco Secure Firewall needs improvement in deployment time and the capability to access the CLI during support calls. I often encounter issues when technical support uses a CLI that is not familiar to me while troubleshooting through the GUI. My ongoing complaint for the last six years has been the lack of CLI functionality, which hinders my ability to work on the firewall, alongside concerns regarding deployment time. For the next release, they should look at the features offered by competitors such as Fortinet, including the ability to perform packet capture directly from the interface. If they enhanced their troubleshooting efficiency related to packet capture for each specific rule, it would simplify the process significantly.

Though it helps deal with web traffic or any malicious traffic, it needs to work on its DC performance issues

Bhaskar Rao

Network manager admin at Yamaha

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 most important features with FortiGate are the web filter and application controls. We can control our internet usage and use the web filter for application purposes."

"The integration with Active Directory is one of the good features. Most of the customers are now looking for the Single Sign-on feature. So, being able to integrate Active Directory with the firewall is useful. It is also easy."

"Security management tool that's easy to integrate and easy to work with. No issues found with its stability and scalability."

"The solution is highly scalable because they have devices that can handle a large amount of traffic."

"Fortinet FortiGate has positively impacted my organization, offering ease of management with no network disruptions; it works seamlessly."

"It has improved our organization with control data."

"It is stable and easy to use. There are a lot of good resources available on the web."

"The SD-WAN feature of Fortinet FortiGate has been most impactful in maintaining our network's integrity."

"Firepower has reduced our firewall operational costs by about 25 percent."

"Technical support services are excellent."

"We found the initial setup to be easy."

"The most valuable feature is the Intrusion Prevention System."

"The traffic inspection and the Firepower engine are the most valuable features. It gives you full details, application details, traffic monitoring, and the threats. It gives you all the containers the user is using, especially at the application level. The solution also provides application visibility and control."

"The VPN functionality is consistent, and the performance is good."

"I work with Cisco and other partners, but the Cisco team is the best team in our country. When I call them, they always help us."

"The ASA has seen significant improvement due to the IPS."

More Cisco Secure Firewall pros

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

"The solution is scalable."

"The product’s firewall and VPN package are fantastic compared to any other solution."

"The initial setup is straightforward."

"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."

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

"Since it is really customizable, I can use it and avoid enabling access to the full network."

"The solution offers good sandboxing."

More Zscaler Cloud Firewall pros

Cons

"We had a minor problem where there was a major system upgrade on the hardware platfrom and the Mac client was not available as soon as it might have been. The PC client was available immediately, but we had to wait a month or so, before there was a mac client. I was slightly irritated that it was not ready on time, but it was eventually resolved."

"The renewal price and the availability could be improved."

"I would like to see improvements in Fortinet FortiGate regarding the active-active scenario. The active-active scenario is supported but not recommended, whereas other vendors are implementing active-active without issues. Perhaps in the future, we could effectively use both firewalls to increase the throughput. If there are two boxes, they both should be able to work."

"They could improve the response time and quality of support."

"Some of the filtering is not robust, you can escape it with a VPN. Some of the users bypass some of the filters. It catches some but it also misses some, that area could be improved. It's functioning reasonably but there's room for improvement in that area."

"I would like to see more advanced developments of a wireless controller in the future."

"The user interface of the Fortinet FortiGate management console could be more intuitive and user-friendly, and the log analysis and reporting features could be enhanced to provide more flexibility and customizable insights."

"Lacks sufficient security options."

More Fortinet FortiGate cons

"Cisco Secure Firewall should be easier to handle. It uses ASDM, which is not easy to understand. It would be better if there was direct access via HTTPS."

"Other firewalls, upgrading is a very easy task; from the graphical user interface, you just need to import the firmware versions into it and install it. In this firewall, you need to have a third-party solution in both. It's a process. It's a procedure, a hard procedure, actually, so there is no straightforward procedure for upgrading."

"In my experience, a number of engineers get tunnel vision with devices. This is exacerbated by vendors fostering a silo mentality in disciplines."

"The interface for monitoring could be improved to allow better views to make troubleshooting easier."

"It is my understanding that they are in the process of discontinuing this device."

"The ability to better integrate with other tools would be an improvement."

"It lacks management. For me, it still doesn't have a proper management tool or GUI for configuration, logging, and visualization. Its management is not that easy. It is also not very flexible and easy to configure. They used to have a product called CSM, but it is no longer being developed. FortiGate is better than this solution in terms of GUI, flexibility, and user-friendliness."

"They should allow customers to talk to them directly instead of having to go through the reseller."

More Cisco Secure Firewall cons

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

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

"The issue right now is probably that Zscaler is not providing web browser isolation. Another solution, Menlo, offers this. For one customer, we had to send traffic to Menlo to do the isolation for us. It was requested by the customer so that they could integrate any iframe. Zscaler needs to add this type of feature in their next release."

"They do not provide a few components that are fundamental to differentiate the products"

"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."

"Its technical support services could be better."

"When it comes to customer support, there is room for improvement in Zscaler's service."

"If I can get rid of Jetscaler, I will use Twingate for sure."

Pricing and Cost Advice

"In the Asian economy in which we operate, FortiGate is expensive."

"If you purchase a one-year subscription with the hardware and then you want to renew for the second year, it is very costly."

"Currently, we are paying about $1,500 a month for three sites."

"Fortinet FortiGate allows you to purchase licenses for hardware and software."

"Fortinet FortiGate as a less expensive solution than Palo Alto."

"By default, they give SD-WAN along with the firewall. They don't have separate licensing for the SD-WAN functionality. However, they have security licenses that are sold separately on a subscription basis. Customers can consume these security features to protect their users from internet traffic."

"There is a subscription-based model to use Fortinet FortiGate. We pay annually for the solution along with the support. If you want to have all the updates, and security patches you will need to renew your support."

"The price of FortiGate support is too expensive."

More Fortinet FortiGate pricing and cost advice

"I know that licensing for some of the advanced solutions, like Intrusion Prevention and Secure Malware Analytics, are nominal costs."

"They seem to be at the top end in terms of pricing, but they are worth the price. They are probably a little bit lower than Palo Alto. If the customers are relying on Cisco products and they are thinking more in terms of scaling to another layer in a year, it is pretty much in a good price range."

"When it comes to Cisco, the price of everything is higher. Cisco firewalls are expensive, but we get support from Cisco, and that support is very active."

"There are additional implementation and validation costs."

"There are licensing costs."

"We've compared it to other solutions, like WatchGuard and other types of firewalls in that same realm. Cisco ASAs are fairly priced and very competitive with them."

"We have a perpetual license for all of our firewalls. For some of the features, we purchase them on demand. The pricing is decent but it could always be cheaper, we would be happier."

"The pricing is fair compared to competitors."

More Cisco Secure Firewall pricing and cost advice

"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."

"It is expensive for small businesses."

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

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

"There is an annual license required for the use of the Zscaler Cloud Firewall."

"There are different subscription models available."

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

"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."
