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
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.

Is stable and has a user-friendly dashboard and a good interface
We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good We cannot secure a specific IP class with this firewall. Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the…

Quotes from Members

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

Pros

"We are very happy with the general bandwidth agility we have seen from one website to another website."
"A strong point of FortiGate is the graphical interface is complete and easy to use."
"The most effective features for threat prevention are the IPS, content filter, and SD-WAN capabilities."
"FortiGate is easy to use, and I also like its VPN."
"We purchased Fortinet because of the pricing, its functionality, because it met our requirements, and the total cost of ownership over five years was quite reasonable. In the market, Fortinet is rated quite well."
"The most valuable feature is the bundled subscription, which is IPS, TV and web filtering."
"The security features that they have are quite good. On top of that, their licensing model is quite nice where they don't charge you anything for the SD-WAN functionality for the firewall."
"Fortinet FortiGate has positively impacted our organization by preventing hackers from accessing our network."
"The ASA has seen significant improvement due to the IPS."
"It helped us a lot with our VPNs for the home office during COVID. There has been more security and flexibility for VPNs and other applications."
"The most valuable features are the flexibility and level of security that this solution provides."
"I am used to the ASA syntax, therefore it is quite easy to make up new rules. I have found that DNS doctoring rules are useful."
"It is a very stable product. I've not had any issues with it. It is a super product, and I won't need to change it anytime soon."
"Cisco ASA NGFW significantly improves our bank. It protects any high-value products that we use from hackers, viruses, malware, and script-bots. It gives us metrics on network traffic as well as what kind of attacks we are getting from the outside."
"What I found the most valuable about Cisco Secure Firewall is that if a client is educated about the solution, it can help him or her avoid many problems and mistakes."
"A powerful enterprise security solution that is dependible."
"The only firewall able to monitor traffic from a CCTV network. Can detect unauthorized devices plugged into the network, which standard firewalls can't do."
"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"It has been stable so far."
 

Cons

"One area for improvement is the IPS engine."
"I have contacted the support from Fortinet FortiGate IPS. The service was good but the speed could be better."
"I would like to be able to generate reports about the protections that we have. I would like a report feature."
"Its load balancing feature could be easy to configure."
"I would like reporting to be improved and should offer a lot more tools to monitor the products."
"There is an area for improvement in vulnerability management."
"I prefer Palo Alto over Fortinet FortiGate. Its IPS engine is not better than the Palo Alto version. The monitoring tool needs improvement, and the syslog configuration needs enhancement."
"The UTM filtering needs improvement."
"The price can be better."
"Cisco Secure Firewall’s customer support could be improved."
"It could also use a reporting dashboard."
"MSSP oriented interface: I would like a single console which would allow me to manage settings creating consistency across all customers."
"Its configuration through GUI as well as CLI can be improved and made easier."
"In NGFW, Cisco should be aligned with the new technology and inspection intelligence because Cisco is far behind in this pipeline."
"Comparing Cisco solution to others, it is expensive, it would be better for it to be cheaper."
"Critical bugs need to be addressed before releasing the version."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the hotspot get all the functions, and the security does not work."
"Licensing is not cheap."
 

Pricing and Cost Advice

"If you compare Fortinet FortiGate with Sophos and other firewall products available in the market, this solution is affordable."
"We are currently evaluating a Palo Alto solution, and the pricing could be a reason for going for Palo Alto."
"Fortinet FortiGate is cost-efficient. Palo Alto is expensive, but Fortinet FortiGate is not."
"If you are looking for a quality product, it will come at a higher price. Expecting them to be significantly cheaper is unrealistic. In terms of pricing, it is a bit costly. However, the functionality and support offered are worth it."
"Cost-wise, there is not much difference from Sophos, but feature-wise, we get more features."
"Pricing for Fortinet FortiGate SWG is more suitable for enterprise or large-sized organizations because they are the ones who can afford it versus small and medium-sized organizations."
"FortiGate Next Generation Firewall is an expensive solution."
"Fortinet is the least expensive solution."
"When we purchased the firewall, we had to take the security license for IPS, malware protection, and VPN. If we are using high availability, we have to take a license for that. We also have to pay for hardware support and technical support. Its licensing is on a yearly basis."
"To discuss with Cisco Systems or their partners to gain the optimal price and to not consider, without verifying, the false information that Cisco ASA is very expensive."
"Acquiring licensing for Cisco Secure Firewall can be a bit cumbersome, therefore a more straightforward licensing process would be preferable."
"Cisco is not for a small mom-and-pop shop because of the cost, but if you're in a regulated industry where a breach could cost you a million dollars, it's a bargain."
"I know that licensing for some of the advanced solutions, like Intrusion Prevention and Secure Malware Analytics, are nominal costs."
"The price of Firepower is not bad compared to other products."
"In terms of scalability, it is really expensive. It is scalable, but when it comes to pricing, the upgrading is a bit high."
"We are partners with Cisco. They are always one call away, which is good. They know how to keep their customers happy."
"We got a much cheaper price than that provided by Fortinet right now."
"On a scale from one to ten, with one being low and ten being high price, I would rate the price of Hillstone T-Series at three. There are no additional costs other than renewal costs."
