Manager, Information Technology Operation/Presales at TechMonarch

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.

Secures users wherever they are and enable us to inspect SSL traffic, but we encountered too many issues

The solution should have no impact but it does have a bit of impact on end-users. For example, we encountered some issues in the downloads that took longer than they did without using Menlo. That is clearly not transparent for users. We expected not to have any latency when downloading anything from the internet with Menlo compared to without Menlo. We are now transitioning to another solution. The main reason for that is that managing all of the exceptions and troubleshooting all of the issues our users have had connecting to the internet has become too significant in terms of workload, compared to what we hope we will have with another solution. In other words, we hope to get the same level of protection, while reducing the number of visible bugs, issues, latencies, impacts on performance, et cetera, that we have today with Menlo. We already solved most of them, but we still have too many such instances of issues with Menlo, even though it is protecting us for sure. The weak point of the solution is that it has consumed far too much of my team's time, taking them away from operations and projects and design. It took far too much time to implement it and get rid of all of the live issues that we encountered when our users started using the solution. The good point is that I'm sure it is protecting us and it's probably protecting us more than any other solution, which is something I appreciate a lot as a CISO. But on the other hand, the number of issues reported by the users, and the amount of time that has been necessary for either my team or the infrastructure team to spend diagnosing, troubleshooting, and fixing the issues that we had with the solution was too much. And that doesn't include the need to still use our previous solution, Blue Coat, that we have kept active so that whatever is not compatible or doesn't work with Menlo, can be handled by that other solution. It is far too demanding in terms of effort and workload and even cost, at the end of the day. That is why we decided to transition to another solution. If we had known in the beginning that we would not be able to get rid of Blue Coat, we probably would not have chosen Menlo because we were planning to replace Blue Coat with something that was at least able to do the same and more. We discovered that it was able to do more but it was not able to replace it, which is an issue. It is not only a matter of cost but is also a matter of not being able to reduce the number of partners that you have to deal with. In addition, they could enhance the ability to troubleshoot. Whenever a connection going through Menlo fails for any reason, being able to troubleshoot what the configuration of Menlo should be to allow it through would help, as would knowing what level of additional risk we would be taking with that configuration.

Director at Aquila ICT Solutions

Has streamlined secure deployments across large enterprises while offering reliable protection and intuitive management

The centralized management console, also referred to as the Zscaler dashboard, impacts the ability of my customers to respond to security incidents significantly. I see it as user-friendly, and clients are really happy with using it, which motivates them to keep using Zscaler Cloud Firewall because they enjoy the GUI. It's very intuitive, making it easy to navigate alerts and incidents. My clients rarely have questions about where to find specific information once Zscaler Cloud Firewall is running. The interface speaks for itself, requiring little to no additional training, which is a major plus. Advanced threat protection features in Zscaler Cloud Firewall are practically the key component that every customer wants. Unfortunately, it is an option and not included in the basic package. Clients need to pay for the next higher bundle to access it, but practically all clients I have dealt with want this feature 100%. Regarding visibility, I can confirm that Zscaler Cloud Firewall indeed includes a feature for application layer visibility embedded in the service. It provides visibility into what you're doing, which is especially interesting nowadays when discussing AI tools, as companies do not want their employees to copy-paste sensitive information into AI systems. We have seen cases such as Samsung's chip design where sensitive info got exposed. The visibility of applications, including cloud applications and AI tools, is significant for compliance with data policies, and you can also run reports and alerts on it.

Quotes from Members

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

Pros

"It's super reliable. I don't think I've ever had a reliability issue with it."

"You have access to CLI in case you have no web access."

"This is a quality product with ok support, and it is better than the competition we've tried."

"It's safe and secures my network and applications in some sites."

"The security features are valuable, particularly the ransomware attack protection features. Fortinet FortiGate provides excellent security against ransomware attacks."

"It is easy to use and update the software version. It is also useful for integration with other Fortinet products, because my office and company use Fortinet solutions."

"The performance is good."

"We are a visual effects company, and there have been a number of high profile security issues in our industry. This has brought us to a higher standard of security, which our clients are very keen on these days."

More Fortinet FortiGate pros

"It has reduced security events to follow up on. While it is not 100%, there has been probably a 90% or more reduction. We were getting hit left, right, and center constantly from people browsing the Internet and hitting bad websites. It was not just bad websites that were stood up to be malicious, but good sites that were compromised."

"For us, the primary goal is protection on the web, and that's extremely important. We're not using any of the other services at this time. The web part is key to the success of the organization. It gives us the ability to protect. It can isolate. It opens the session in an isolated format so that the code isn't running locally. It is running over in the Menlo environment, not in ours. It is not running on the local computer, whereas if you were to go to a normal website, it would run Java or something else on the local machine and potentially execute the malicious code locally. So, it does give us that level of protection."

"The fact that it is a cloud proxy solution is another feature we like. For example, if you acquire a new company, you can use it to protect that new company without the need to install anything physically on their networks."

"Accessing the internet with a proxy from anywhere is the most valuable feature. It ensures that users are only able to browse legitimate websites. If they happen to go to a legitimate website with a malicious payload, the isolation feature will take care of that."

"This security technology addresses risk and enables people to conduct business without that risk, which is where the ROI is realized."

"The centralized management console, also referred to as the Zscaler dashboard, impacts the ability of my customers to respond to security incidents significantly, and clients are really happy with using it, which motivates them to keep using Zscaler Cloud Firewall because they enjoy the GUI."

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

"Includes advanced tech protection."

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

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

"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."

"It helps a lot of companies to reduce their downtime. Also, It helps businesses in terms of being secured and protected from any threats."

More Zscaler Cloud Firewall pros

Cons

"It's one of the more expensive brands."

"Compared to some other products, the DLP is not at par for the moment."

"The solution could improve the configuration, there are times the configuration is missing."

"They can do more tests before they release new versions because I would like to be more assured. We had some experiences where they release something new and great, but some of the old features are disabled or they don't work well, which impacts the product satisfaction. The manufacturer should be able to prove that everything works or not only that it might work. This is applicable to most of the other services, software, and hardware companies. They all should work on this. We cannot trust every new release, such as a beta release, on the first day. We wait for some comments on the forums and from other companies that we know. We always wait a few weeks before we use the updated version. They should also extend the VPN client application, especially for Linux versions. Currently, it has an application for Linux devices, but it doesn't work the way we want to connect to the VPN. They use only the old connection, not the new one. They have VPN client applications for Windows and Mac, but they can add more useful features to better manage the devices and monitor the current health of each device. Such features would be helpful for our company."

"Its customer service could be better."

"I would like to see improvements in the IPS/IDS feature to enhance protection against attacks from attackers, including ransomware protection."

"They should make the rule sets more understandable for the end user. When you're trying to explain to somebody how a computer network is secured, sometimes it's difficult for an end user or customer to understand. If there was a way to make the terminology more accessible to the end user, the set up could be easier. They should translate the technical jargon to an easily relatable and understandable conversation for the end user, the customer, that would be brilliant. Particularly in an environment where the IT structure is audited regularly, there's always pressure from the auditor to up the standards and up the security and you get your USCERT's that come out and there's a warning about this and the customer will want to lock out so much and when you apply it they run into issue where they can't search the internet or print to their remote office. Of course they can't print to your remote office, they just locked it up. They should make the language more understandable for the customer. If there's a product out there that made the jargon understandable to John Q. Public, I would buy that."

"The logging details need to be improved."

More Fortinet FortiGate cons

"In the best of all worlds, we wouldn't have to make any exceptions. However, that is a big ask because a lot of that depends on how websites are constructed. For example, there are some very complex, application-oriented sites that we end up making exceptions for. It is really not that big an issue for us to make the exceptions. We feel like we are doing that without a huge impact on our security posture, but we do have to make some exceptions for complex sites, e.g., mostly SaaS-type sites and applications."

"Currently, I don't have a good way to see which of my rules are being used in the access control lists. I have numerous entries, but are they all still needed? A report that would show me my list of who is allowed and whether we're actually using it would be useful because I can then go clean up my list. It would be easier to manage. We would eliminate the vulnerability of unused services."

"We are now transitioning to another solution. The main reason for that is that managing all of the exceptions and troubleshooting all of the issues our users have had connecting to the internet has become too significant in terms of workload, compared to what we hope we will have with another solution."

"Menlo Secure is a smaller company with limited resources and funding, which makes it challenging to compete with larger companies such as Palo and Cisco."

"The user monitoring could still be improved."

"Pricing is a challenge."

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

"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."

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

"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."

"There are several areas for improvement. Firstly, the GUI is outdated, with noticeable lags and delays, especially when generating reports for past transactions."

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

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"It's a very full-featured and it's priced well solution."

"Fortinet has one or two license types, and the VPN numbers are only limited by the hardware chassis make."

"FortiGate's pricing falls within the mid-range when compared to other leading firewall solutions."

"If the price of the license in Fortinet FortiGate was less expensive it would be better."

"It is not a very costly product if you compare it with other products. The return on investment is also good. If you compare the return of investment and money that you are spending on this product with Palo Alto, Cisco, Check Point, and other solutions, the investment is very less. We are happy with this solution. The optional licenses are there, and you can choose which one you want and which one to avoid."

"It is a good product from a price perspective versus functionality."

"Fortinet FortiGate is cheaper than Palo Alto. It is about 20% cheaper."

"The price of Fortinet FortiGate is better than Cisco, Check Point, and Palo Alto. In terms of pricing, it's probably a better-priced firewall solution overall."

More Fortinet FortiGate pricing and cost advice

"The solution is expensive. It's more expensive than the solution I previously used. Compared with the other cloud-based solutions, it's very competitive."

"It is appropriately priced for what they're doing for us. Considering the protection provided, I feel their pricing is spot-on."

"We save a ton of money and time. Previously, the numerous hits that we were receiving from our security tools, prior to implementing them, had to all be chased down, dispositioned, and endpoints had to be reimaged. It was just a ton of effort to do all that. That is where the savings from time and money come in."

"It is not the most budget-friendly solution, but it's important to consider its overall value."

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

"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."

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

"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."

"There are different subscription models available."
