Effective threat prevention with responsive customer support
We are using Fortinet FortiGate as a firewall Fortinet FortiGate has been invaluable. It has helped save costs due to its various features, reliable performance, very good UI, low latency, and stability. The Threat Intel engine in Fortinet FortiGate is highly rated for its effectiveness in…

Good interface and firewall capabilities and overall easy to use
The security has improved as we can isolate the network. We can do attrition prevention via a tool that comes with the solution. We can have a VPN solution in place for those that work from home, outside the network, in a secure manner. We also like that it offers good authentication. It offers radius-based authentication, which has been useful for the company. The main platform is under the Open VPN firewall. The solution has high availability. When we have different ISPs, we can actually load balance those links or actually put some priority or even classify the traffic that might go into one ISP or another.
Vikram Srirama. - PeerSpot reviewer
A highly scalable solution that helps monitor and block undesired, non-standard traffic
Zscaler Cloud Firewall is a cloud-based solution. Zscaler Cloud Firewall is a good product. Since it's a SaaS product, most of the maintenance of devices is eliminated, and it is bundled with your secure web gateway. People should use Zscaler Cloud Firewall for their remote users or work-from-home users. Overall, I rate Zscaler Cloud Firewall a nine out of ten.

Quotes from Members

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

Pros

"FortiGate firewalls are easy to manage through a user-friendly web interface. They also have advanced features like DDoS and DLP. However, I wouldn't recommend enabling all of these features on one device because it can cause performance issues."
"The most valuable feature is the interface, which is very user friendly. We are utilizing most of the features, like content filtering. The firewall is powerful."
"This solution has helped our organization by having strong functions and a reliable firewall."
"The interface is very user-friendly and I like it very much."
"Initial setup is easy to configure."
"I think that the UTM features are the most value, as it truly protects my infrastructure."
"The features that prevent internet connections, the filtering are the most valuable because we did not have any internet protection before."
"The pipe filter application is an outstanding feature."
"The tool's integration is more like a button press."
"The technical support is very good."
"The solution is user-friendly and easy to configure."
"URL blocking, Wireguard, Tail Scale, Engine Blocker, and VPN are the most valuable features for me."
"It's open source."
"It is a very good solution. I like the dashboard. I can see what is going on and manage it as I like it."
"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use."
"The interface and the dashboard are the most valuable features of this solution."
"Zscaler provides effective protection against various cyber threats ensuring a safe environment"
"It is a stable solution."
"If malicious traffic attacks our on-premises servers, then it gets blocked by Zscaler Cloud Firewall."
"The solution is scalable."
"Zscaler Cloud Firewall understands the applications in the current generation and adapts to the present generation cloud applications."
"Most of the features that Zscaler has to offer, we will deploy."
"The solution offers good sandboxing."
"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."
 

Cons

"Application management can be improved."
"I would like Fortinet to add more automation to FortiGate."
"I don't like that anything more than very basic reporting is not included."
"Fortinet needs more memory to save the log files. We need it to save the logs on the hardware and not in the cloud. I know this feature is available in FortiCloud, but if we need this log locally, it is not available."
"Fortinet FortiGate could improve by adding enhancements to FortiMail, FortiSOAR, and FortiDeceptor."
"Lacks training for new features."
"With the addition of some features, it is possible that FortiGate can be used in all verticals."
"The solution can have more features in a single box that can be multi-applied to integrate everything."
"The interface of the solution is an area with shortcomings."
"An area for improvement in OPNsense is the hardware, which needs to be updated more frequently. DNS blocking is another good feature I want to be added to the solution. pfSense has a peer-blocking feature that I also want to see in OPNsense."
"The logging could improve in OPNsense."
"The solution would not be suitable for anything large-scale."
"There is room for improvement in SSL inspection."
"When using the solution at the beginning was difficult. There was a steep learning curve."
"OPNsense struggles to handle large volumes of voice traffic, indicating scalability issues in that specific use case."
"There should be more technical documentation."
"When it comes to customer support, there is room for improvement in Zscaler's service."
"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."
"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."
"They do not provide a few components that are fundamental to differentiate the products"
"Pricing is a challenge."
"Certain criteria need to be met if you want to scale this solution."
"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."
"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."
 

Pricing and Cost Advice

"We find the most valuable aspect of this solution is the price. It is affordable, and cheaper than other firewalls."
"Fortinet FortiGate's price can be reduced."
"If you purchase a one-year subscription with the hardware and then you want to renew for the second year, it is very costly."
"Its price is affordable and lesser than Cisco. Cisco is expensive. In terms of licensing, there is only one issue. If a customer's license has expired a month ago and they do the renewal after one month, Fortinet renews the license from the start of the previous month. The activation of the product is done from the previous month, not from the date of renewal. The customers usually shout and complain that because they are paying today, the renewal should start from today. The support contract renewals or licensing should be renewed from the date of renewal, but Fortinet starts from the day it had expired. It is a loss for customers. They might have had some problems because of which they did not take the license one month before. Fortinet should work on this. Cisco doesn't do this. Cisco always starts from the day they apply for the license."
"Fortinet has more device options that are affordable for small businesses than Palo Alto, and its enterprise-level models are also cheaper. Palo Alto also has a separate license for VPN connections and SD-WAN, but FortiGate offers these features standard."
"The price of the license and warranty can be better because it is very expensive."
"The pricing is perfect."
"The price, in comparison to other products is very cheap."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
"It is open source and free."
"It's not expensive."
"I would rate the pricing three out of ten."
"As an appliance, it's in the medium price range."
"We are using the paid version."
"It costs about $1000."
"It is free."
"There is an annual license required for the use of the Zscaler Cloud Firewall."
"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."
"It is not the most budget-friendly solution, but it's important to consider its overall value."
"There are different subscription models available."
"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."
