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.

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

"Our project needs to link two sides through the internet. One of these was in Cairo and the other in another city. We used FortiGate as the integrating solution between the two locations, i.e. the Fortinet 30E & 100E."

"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."

"The reporting you receive out of this appliance is excellent. You will not need an external management system."

"It's great for capturing the traffic and troubleshooting it."

"Fortinet FortiGate has positively impacted our organization by preventing hackers from accessing our network."

"The initial setup is very straightforward and easy, with wizards helping to configure the device efficiently."

"FortiGate's ability to perform as expected and fulfil our needs has been the most compelling feature for network security."

"We use a southern institution that's audited for IT security and the reporting that automatically comes off the unit makes it much easier to meet compliance standards and makes it easier as far as the amount of time that has to be spent to compile that information. If you get your reporting set up correctly when you initially set it up, you just select the one you want and hit print. The auditing trail on it is the best feature."

More Fortinet FortiGate pros

"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."

"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."

"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."

"Most of the features that Zscaler has to offer, we will deploy."

"Includes advanced tech protection."

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

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

"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 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."

"The initial setup is straightforward."

"It is a stable solution."

More Zscaler Cloud Firewall pros

Cons

"In the past six months, they took quite a long time to respond to the support tickets. I don't know if they are overwhelmed with too much activity, but for the last six months, the support has not been very good."

"They should improve high CPU and memory usage that occurs."

"The reports are very basic."

"Regarding challenges, customers initially faced issues like internet dropping, but after firmware upgrades, everything worked well."

"Some of the web policy reports could be improved."

"Fortigate's hardware capacities could be improved."

"Improvements for Fortinet FortiGate could be made by making it easier to implement on networks and simpler to add users and accounts that utilize this solution. That's basically the only challenge that I see."

"A sandbox would be good in order to be able to inspect the emails containing spam and be able to validate the emails that contain malware, prior to delivering to the customer."

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."

"The user monitoring could still be improved."

"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."

"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 having some issues with internet access being denied when organizational ID-based policies change. For example, a lower level employee ends up getting the same level of access as that of a higher level employee."

"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."

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

"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."

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

"Pricing is a challenge."

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

Pricing and Cost Advice

"We have the full version of Fortinet FortiGate and we are on a three-year contract with a commitment of five years."

"It has been two years. I don't remember the actual price, but it was affordable. We buy the boxes and then use the license for three years."

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

"The beauty is the price performance ratio is great with FortiGate. It provides all the features we needed and the price is comparable with others' firewalls. The price is quite competitive with the firewalls with similar features."

"The price is fair compared to the other competitors."

"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."

"It is very cost-effective. You get features similar to other firewalls, such as Palo Alto, but at a lower price."

"It is too expensive for us. My organization is very small, and we have a total of ten users. We have three internal users and seven external users. The FortiGate 100D series is too expensive for renewing the licenses."

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."

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

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

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

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

"It is expensive for small businesses."

"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."

"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."
