Manager, Information Technology Operation/Presales at TechMonarch

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.

Have faced challenges in keeping licensing clear and consistent while ensuring reliable network protection

We are a Gold Partner with Cisco. Our customers come from various industries, including service providers, and we target service providers and enterprise customers.We do not extensively use Zone-Based Firewalls in Cisco IOS Security, instead typically deploying standalone firewalls such as Cisco FTDs or Cisco ASA devices. For threat analytics and vulnerability scanning, we utilize third-party vendors with dedicated devices and software. We use products such as Tenable from Nessus for this type of analysis. We have implemented Secure Access Control Server in Cisco IOS Security, which combines multiple security mechanisms including AAA, 802.1X for network access control with Cisco ICE, TrustSec for identity-based segmentation, and Cisco DNA Center. Cisco IOS Security's VPN support is comprehensive and increasingly important in daily communication, from basic site-to-site tunnels to remote access VPNs and SD-WAN secure VPNs. Protecting and encrypting communication is essential in modern networks. The challenges with Cisco IOS Security are more operational than product-related. There is an understaffing issue, making automation and orchestration capabilities particularly valuable. For the products themselves, we only encounter routine operational matters such as addressing new vulnerabilities and patching. For those considering Cisco IOS Security, it is important to understand that Cisco offers a complete ecosystem. When embracing the Cisco ecosystem fully, customers receive excellent products and comprehensive solutions. On a scale of 1-10, I rate Cisco IOS Security a 9.

It Manager at Diamond Braces

A robust appliance that is reasonably priced and straightforward to set up

Although manageable, the user interface is a little bit slow and could be improved. There are two user interface options available, namely the basic and the advanced. The basic UI is not very good and doesn't have a lot of features, although it is fast. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists. At one of our sites, the CPU utilization was very high, and for no reason. Technical support needs to be more responsive to requests.

Quotes from Members

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

Pros

"All of the features of Fortinet FortiGate are useful and the security protection is good."

"The strengths of Fortinet FortiGate include network security, VPN, site-to-site tunnels, client VPN solutions, two-factor authentication for VPN clients, and SD-WAN for branch level. We have implemented these solutions for various customers."

"The security on offer is very good."

"I like FortiGate's zero-trust capabilities and protection against zero-day threats. Zero-day threat protection is critical because we're seeing constant changes in the threat landscape. The sandboxing and web access controls are also robust."

"FortiGate Next Generation Firewall has a stateless balance proposition"

"I appreciate FortiGate for its reliable, powerful, and flexible setups."

"The tool is a nice product and easy to handle. The software's user interface is also good. You can easily implement remote access in the solution."

"Good anti-malware and web filtering features."

More Fortinet FortiGate pros

"The most valuable features are DNS service and shell self-service within a network."

"Cisco is head-and-shoulders above all of the competition when it comes to technical support."

"The product has valuable features for business intelligence."

"Cisco IOS allows us to keep the same security features as our principal offices."

"It is less expensive than alternative firewalls."

"You can scale it when you need to."

"The solution is stable."

"The security is very good."

More Cisco IOS Security pros

"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."

"The solution can scale well."

"This is a capable appliance and the standard features work well for us."

Cons

"One drawback of Fortinet FortiGate is that they provide two types of models: one with a hard disk and another without. The model without a hard disk has very low ROM where you can store very few logs, after which you need to upload it to the cloud or purchase a firewall with SSD."

"The SD-WAN functionality is a bit overly complicated and not fully documented."

"The renewal price and the availability could be improved."

"Fortinet FortiGate is not a scalable solution, as they give you a number and each box comes with concurrent connections; if you need to expand, you have to change the box."

"There are problems with the custom reporting of the unique traffic. The data is there, but it is too difficult for us to extract."

"There should be some open-source training or free training for decision makers, or some webinars should be available. These would help understand the new product line and the existing product line features."

"Quality control on their firmware versions needs improvement. When they introduce new firmware, there tend to be bugs."

"Fortinet FortiGate SWG's SSL offloading features need improvement."

More Fortinet FortiGate cons

"The company needs to make its solution more affordable to make it more accessible to larger markets. Otherwise, it's seen as an enterprise-level solution that small or medium-sized organizations can't afford and therefore they won't even look at it."

"The solution is complex and can be more user-friendly."

"With respect to user-friendliness, it is a command-line interface and those with such experience will get along just fine, whereas others may struggle."

"Cisco IOS Security should improve its functionalities."

"I wish it would be more like the next generation firewall technology. There should be more selection between the application and filtering."

"Sometimes I find it difficult to manage. Some configurations are difficult for new engineers, for example."

"We faced significant challenges related to licensing issues, particularly when licenses expire."

"We need to pay for the license and it is expensive."

More Cisco IOS Security cons

"Although manageable, the user interface is a little bit slow and could be improved."

"The product has some scalability and data management issues where improvements are required."

"Sometimes it reboots when you least expect it, and that's the main issue."

Pricing and Cost Advice

"Pricing and licensing is a little bit complicated in FortiGate. They are always on the higher side. This is one issue that we always raise with the company that they should reduce the price according to Indian market requirements. There are no costs in addition to the standard licensing fees."

"Pricing for this product is comparatively lower than other products. It's an affordable solution, but when expanding the number of users, they'll ask you to replace the model, so that's an added cost."

"For the performance that we get, the price is reasonable. There are cheaper options, but they may not deliver the same kind of performance that we want. For the performance they provide, the price is acceptable."

"It's an expensive solution."

"The price of Fortinet FortiGate is the lowest in the market."

"The pricing is flexible."

"I rate the pricing an eight and a half on a scale of one to ten, where one is low, and ten is high."

"The price depends on the size of the company. From the beginning, you just want to know the internet bandwidths, speed, and the number of users to be able to offer the right product and model. They have a lot of products in FortiGate according to the size of the company, like 200D and 300D."

More Fortinet FortiGate pricing and cost advice

"The pricing is average and includes all features with support."

"The pricing is very expensive. Normally I do a yearly contract; I don't know the exact pricing, but it's around $75,000 USD per year. That's the standard licensing."

"The cost may be around $5,000 to $10,000 a year. If you want support you have to pay at least this price."

"The pricing is okay. It is competitive. It costs more when you need get more features."

"Price is certainly something that the IOS technology has fallen behind the competition on."

"I rate Cisco IOS Security's pricing a ten out of ten."

"The pricing for Cisco IOS Security is reasonable compared to other Cisco products."

"Cisco IOS Security price could be reduced, it is more expensive than many of the other solutions, such as Sophos and Fortinet FortiGate."

More Cisco IOS Security pricing and cost advice

"This gateway is pretty cheap."

"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
