Sentiment score
6.9
Fortinet FortiGate support varies, praised for responsiveness but criticized for slow responses and regional inconsistencies in efficiency.
They offer very accurate solutions.
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.
I would rate the technical support for Fortinet FortiGate a ten out of ten.
 

Scalability Issues

Sentiment score
7.5
Cisco IOS Security is praised for scalability and efficiency but may require additional hardware and specific Cisco equipment.
Sentiment score
7.3
Fortinet FortiGate is scalable with ease of expansion, though hardware integration and sizing can pose challenges for users.
They scale up really well from smaller models like the FortiGate 40 and 50 to bigger sites with the FortiGate 100 for more throughput - up to enterprise datacenters.
The variation comes in terms of the interfaces and throughputs, but from a security perspective, you get the same benefit, irrespective of whether you have an entry-level unit or an enterprise.
We determine sizing based on multiple factors: number of users, available links, traffic types, server count, services in use, and whether services will be published.
 

Stability Issues

Sentiment score
7.7
Cisco IOS Security is praised for stability and reliability, with few integration issues reported when not using Cisco equipment.
Sentiment score
7.8
Fortinet FortiGate is favored for its stability and reliability, with some performance issues resolved through updates and sizing.
I find Cisco IOS Security to be a very stable product.
We're experiencing 99.999% availability consistently.
I would rate the stability of Fortinet FortiGate a ten out of ten.
The solution is very stable.
 

Room For Improvement

Cisco IOS Security needs more intuitive management, better performance, advanced features, and improved integration, usability, and support.
Fortinet FortiGate users seek improvements in stability, integration, scalability, cost, and advanced features like monitoring and zero-trust technology.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
The constant daily revisions necessitate meticulous identification of the relevant documents to prevent the use of outdated information that could jeopardize our environment.
While Fortinet claims to offer a comprehensive network solution, it falls short in addressing computer application issues, particularly server security.
 

Setup Cost

Cisco IOS Security is pricey, subscription-based, aimed at medium-to-large enterprises, with recent SMB options, often seen as expensive.
Fortinet FortiGate offers various licensing models, balancing affordability and performance, though renewals can increase costs.
FortiGate is priced lower than Palo Alto.
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.
It is about 20% cheaper.
 

Valuable Features

Cisco IOS Security enhances network security with robust features, user-friendly interface, and strong performance, preferred over competitors.
Fortinet FortiGate provides robust security features, user-friendly management, and scalability, making it a preferred choice for organizations.
This solution, called Network Access Controller, handles authentication, authorization, and accounting for devices accessing the network.
In terms of security, we have not experienced any security flaws or loopholes, and it has proven to be quite stable.
FortiGate has helped reduce the risk of cyberattacks that might disrupt our client's production.
These features help reduce our downtime, manage the ISPs, and deploy SLAs for all the website traffic.

Rrobust network security and device authentication with advanced access control features
This solution should be implemented for most enterprise-level customers. It ensures that users accessing the corporate network or wireless network with their own devices are authenticated and authorized. As a network administrator, I can track who is accessing the network, what devices they are…
Vasu Gala - PeerSpot reviewer
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.

Sophos UTM vs. Fortinet FortiGate
I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…
