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.

Offers good features like URL filtering, IPS, and IDS to users

We received an update for the tool in July. The update was provided for the tool as there was a problem with the firewall, where too much memory was consumed, and the firewall was hanging a lot. When we updated the tool's features, everything became okay. The tool only had some memory-related problems. It took the tool a month to fix the issues.

Quotes from Members

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

Pros

"The most valuable features of the FortiGate firewall include SSL inspection, VPN functionality, and threat intelligence features for preventing threats."

"Fortinet FortiGate has SD-WAN, FortiView, antivirus, sandbox, and IPS, which are generally well-known features."

"FortiGate protects and secures our clients' networks. The security is solid, and it performs well. I think they use some artificial intelligence, so I think it's excellent equipment."

"The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with."

"Advanced routing (RIP, OSPF, BGP, PBR). It gives you a seamless and simple integration into a large network."

"A strong point of FortiGate is that the graphical interface is complete and easy to use, especially if we think there is a list of operations that we are able to perform inside."

"There are multiple features I have found to be valuable, such as encryption and integrated security features."

"FortiGate is more feature-rich and has a broader range of hardware. T"

More Fortinet FortiGate pros

"VPN and firewall are good features."

"On the network side, where you create your rules for allowing traffic — what can come inside and what can go out — that works perfectly, if you know what you want to achieve. It protects you."

"I like the user interface because the navigation is very easy, straightforward on your left side pane you have all the sites that you need to browse. Unlike any other firewalls, it's pretty straightforward."

"Once configured to suit your needs, these firewalls are rock solid appliances."

"The most valuables feature of this product are given by the comprehensive VPN solutions it offers and its tools for troubleshooting and debugging."

"They are easy to maintain."

"We found the initial setup to be easy."

"The most valuable features are the flexibility and level of security that this solution provides."

More Cisco Secure Firewall pros

"The installation is easy, we have not had any complaints from our customers."

"The most valuable feature of the Hillstone E-Series is its user-friendliness."

"This solution has two main features that we find very valuable; a threat-intelligence option, and a web/application filtering option. The technical support team are very good and very quick."

"Five out of five ROI."

"The most valuable features of the Hillstone E-Series are its hardware capacity, innovation, and the throughput that the hardware can take."

"The initial setup was straightforward. It only took a few hours to deploy."

"Stability-wise, I rate the solution a ten out of ten."

"Working with the Hillstone E-Series has, from a remote perspective, allowed me to give my clients a secure connectivity."

More Hillstone E-Series pros

Cons

"The command line is complicated, and the interface could be better."

"The support structure needs to be improved because every time we contact them, there is a delay in the response."

"The pricing of the solution is expensive, so it could be cheaper."

"The updates Fortinet provides are sometimes unstable."

"Someone without certification and experience with other firewalls might find it a bit more challenging to grasp the FortiGate format and its platform layout."

"The firmware updates are sometimes not stable. The stability issues can vary, sometimes happening once a month or quarterly. New firmware updates can occasionally introduce bugs, causing some policies to fail. We then have to raise a ticket, and Fortinet usually provides a fix within a few days."

"From a reporting perspective, there's room for improvement. They're providing FortiAnalyzer through which one can get some enhancements, but the visibility and reporting still need slight improvement."

"Improvements could be made when companies expand and need better equipment and more licenses."

More Fortinet FortiGate cons

"When we talk about data centers, we are talking about 100 gig capacity or 400 gig capacity. When it comes to active-active solution clustering and resilience and performance, Cisco should look into these a little bit more."

"Cisco provides us with application visibility and control, although it's not a complete solution compared to other vendors. Cisco needs to work on the application behavior side of things, in particular when it comes to the behavior of SSL traffic."

"Deploying configurations takes longer than it should."

"I work for a school, so getting licensing and getting the budget for Cisco Secure Firewall for certain products is a challenge. It's good to have them, however, it costs us a lot."

"One feature lacking is superior anti-virus protection, which must be added."

"Regarding stability and reliability, I have experienced false negative alerts with the CS models, which indicate that my switch has gone down when in reality, it has not. That is a fix that is needed."

"The usability of Cisco Firepower Threat Defense is an issue. The product is still under development, and the user interface is very difficult to deal with."

"There is no support here in Georgia. If something goes wrong, support is not always very helpful with the other firewalls or other products."

More Cisco Secure Firewall cons

"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."

"The tool needs to improve its price."

"SSL VPN license cost is not cheap."

"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."

"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."

"The current usage reporting is very basic."

"Having frequent live webinars on a monthly basis would really help."

"The tool only had some memory-related problems."

More Hillstone E-Series cons

Pricing and Cost Advice

"The price is okay."

"It was pretty affordable. We did go a little bit above MSRP, but the service pack that was included was quite worth the additional costs. It is competitively priced compared to other major players in the market. It is significantly cheaper than Check Point, which is a primary competitor. Additionally, its pricing is comparable to that of Cisco's ASA and a few other vendors."

"There is a license to use Fortinet FortiGate."

"It is not the cheapest one, but its price is very competitive."

"It's an expensive solution."

"Pricing is lower than Cisco."

"These boxes are not that expensive compared to what they can do, their functionality, and the reporting you receive. Fortinet licensing is straightforward and less confusing compared to Cisco."

"The price of FortiGate is reasonable as I plan to buy new switches. The initial gadgets are already booted, and the pricing seems normal on the market. As for additional costs, I haven't subscribed to many extra features, so I'm only using what I need. Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us."

More Fortinet FortiGate pricing and cost advice

"I rate the product's price a seven on a scale of one to ten, where one is expensive, and ten is cheap."

"The pricing seems fair. It is above average."

"Based on the services that you will get, especially the AMP license, the price is very reasonable."

"Cisco is considered to be an expensive solution."

"It was pretty good and not expensive on the subscription side. Cisco is doing a good job on this."

"The price is not too high, but the subscription is a little bit high. We compared the activation of Cisco and Fortinet, and when we activated the whole portfolio of the UTM of Fortinet, the speed reduced. We tested the same situation with the Cisco 2140 series, and there was no reduction in speed."

"The Firepower series of appliances is not cheap. I just got a quote recently for six firewalls that was in the range of over half-a-million dollars. That's what could push us to look to other vendors..."

"In terms of costs, other solutions are more expensive than Cisco. Palo Alto is more expensive than Cisco."

More Cisco Secure Firewall pricing and cost advice

"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."

"The cost per year for licensing, and hardware, is approximately $850 for the basic plan."

"Hillstone's pricing is economical and neither very high nor very low."

"The tool's pricing is reasonable. It depends on the model. The product's pricing is around 600 USD. You need to buy a software license to activate the features. You need to pay around 150 USD for that."
