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.

Thorough with all-in-one security functions and good affordability
The all-in-one gateway security functions and the ability to install it on generic equipment stand out. The centralized management console is great. I can template my installations and configurations. My ability to monetize it as a gateway security appliance to offer enhanced service offerings allows me to increase our price point. I provide it as a managed device to many of our clients. I take on the initial costs and charge them a monthly fee. They have threat detection.

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

"SSL-VPN is very useful for us and has been very reliable."
"Provides good firewall security and has great VPN features."
"The dynamic segmentation feature in Fortinet FortiGate is pretty good."
"The Intrusion Prevention System and the web filtering are both working well."
"The scalability is easy with switches and access points that are basically plug-and-play for the most part."
"Fortinet offers the latest versions to cater to the needs of enterprises."
"This is an easy solution to deploy."
"Fortinet FortiGate is a very good next-generation firewall."
"None of my clients has had a ransom or breach using Untangle."
"What I like about this product, which is the reason that we continue to use it, is that you can install the software version on your own hardware. In case there is a problem with the hardware, we can just install the firewall in another machine and restore the configuration."
"Easy to set up and easy to integrate."
"The most valuable features are IPS, MAPI, NAT, and VPN."
"Web filtering is very reliable."
"The majority of our clients are very small businesses, and Untangle devices have been fantastic for these small clients. We've basically standardized our stack to just simply use Untangle. We include the hardware and the service option, which makes it very easy and affordable for us to just simply push that into the monthly per-user costing that we provide as a managed services provider. It's really a no-brainer. They're easy to use, and they're easy to set up and configure. Support is generally good about resolving any issues that we have. We haven't had any real complaints."
"All features are useful. We are using premium features such as bandwidth sharing, failover, web filters, SSL controls, antivirus, and VPN. We use these features to the fullest. These features are available in the paid firewall license, not the free one."
"The interface is very good."
"The scalability is okay. We have around 2200 people using this solution."
"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."
"Since it is really customizable, I can use it and avoid enabling access to the full network."
"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."
"Most of the features that Zscaler has to offer, we will deploy."
"The product’s firewall and VPN package are fantastic compared to any other solution."
"It helps a lot of companies to reduce their downtime. Also, It helps businesses in terms of being secured and protected from any threats."
 

Cons

"While FortiGate is cheaper than most other solutions, we're seeing increased license renewal costs. Most of our clients are asking for more significant discounts because the price is going up."
"The reports are very basic."
"There are just some services that aren't available. For example, the Ethernet or point-to-point protocols. They could add these services to their product offering - especially services for ISPs."
"Application management can be improved."
"I would like to see improvements in the support from Fortinet. Here in the Philippines, whenever we have problems with a Fortinet product, we mostly ask for support from distributors and resellers and not directly from Fortinet."
"The performance could be a bit better. Right now, I find it to be lacking. Having good performance is very important for our work."
"The sniffing packets or packet captures, can be simplified and improved because it's a little confusing."
"Technical support could be better. You don't always get the level of help you need right away."
"The management console for partners is a bit tricky (buggy)."
"The product needs to improve its mobile application."
"The ability to setup a DDNS for each WAN independently would be a very handy feature."
"Web-filtering policies could be improved."
"It does have multi-factor authentication in some areas, but I would love to see a more widely implemented version of that on the devices themselves."
"The biggest challenge that we have with this solution is local support. The local support is a problem in our area."
"The user interface, training, and general product innovation need improvement. Enhancements could also be made to their reporting and accessibility."
"The product must improve its reporting features."
"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."
"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."
"Data Leak Prevention is only for web filtering and there is no protection for email."
"I don't have the visibility of a control dashboard or a network management system."
"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."
"Zscaler Cloud Firewall should have a better understanding of all dynamic cloud applications."
"There are several areas for improvement. Firstly, the GUI is outdated, with noticeable lags and delays, especially when generating reports for past transactions."
"Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs."
 

Pricing and Cost Advice

"The license of Fortinet FortiGate should be reduced."
"Fortinet FortiGate as a less expensive solution than Palo Alto."
"The price of FortiGate is good."
"Compared to other firewall products, it's a little cheaper in terms of pricing."
"Licensing for Fortinet FortiGate is on a yearly basis. Pricing for it is a bit high. It could be cheaper."
"Its pricing is competitive with other solutions."
"The price of FortiGate support is too expensive."
"Fortinet is reasonable in pricing and licensing. Overall, FortiGate is affordable. The licensing fee can be a little high, depending on the budget for your project."
"We pay $350 USD per year for the solution. There are no additional costs. As long as you're not using a physical appliance, that's all you need."
"It is not expensive. It is cheaper than Fortinet."
"This is not an expensive product. It is affordable and there are different packages available depending on the features that you need, or the sector that you are in."
"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."
"The tool's pricing is moderate, and licensing costs are yearly."
"The pricing model is better than with SonicWall."
"Untangle is open-source software. So, you can get it for free. That has been a benefit, especially for the residential users because it is free. The license costs start at $25 a month for some additional features, including higher tiers of security intrusion prevention. The free version comes with intrusion detection, and then the license version has intrusion prevention. It also has some additional things for active directory connectors, etc. It starts at $25 a month to cover 12 devices. Then it goes up from $25 to $50 a month for 12 to 25 devices. That's where it really doesn't scale out per site. If you have a site that has more than 50 devices on it, then Untangle quickly becomes cost prohibitive in comparison to several other competitors."
"It is not expensive. The best part is that it is based on the pay-per-use kind of scenario. An increase or decrease in the number of people doesn't make any difference. We are really happy about using this particular scenario."
"It is expensive for small businesses."
"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."
"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."
"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."
"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 is an annual license required for the use of the Zscaler Cloud Firewall."
