Sentiment score
6.9
Feedback on Steelhead scaling varies, with easy deployment praised, but licensing and bandwidth limitations noted by some 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.

Room For Improvement

Fortinet FortiGate needs enhanced UI, simplified licensing, improved performance, reporting, third-party integration, and expanded automation features.
Steelhead users desire improved traffic handling, integration, scalability, security features, intuitive setup, and comprehensive monitoring amid cost concerns.
These sessions should be around five to ten minutes long, allowing users and partners to quickly grasp the information without disrupting their daily tasks.
Managing Director at a manufacturing company with 10,001+ employees
The solution should be able to implement machine learning and analytics of all the logs for threat detection and protection.

It would be better for customers to get immediate replacements even with a standard subscription.

It could still be useful in places with satellite communications, such as the south of Chile, or in the mining industry.

Setup Cost

Enterprise buyers find Fortinet FortiGate costly initially, but cheaper overall, despite some high renewal and setup costs.
Steelhead is costly but valued for performance and support, with complex licensing and varied pricing by usage.
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 offers cost savings as it is generally cheaper than the competition.
IT Infrastructure Architect at Apotek 1
It is about 20% cheaper.

Valuable Features

Fortinet FortiGate provides robust, flexible security solutions with key features like web filtering, SSL VPN, SD-WAN, and centralized management.
Steelhead enhances WAN efficiency with data compression, TCP optimization, and caching, benefiting performance, bandwidth, and cloud migration cost savings.
These features help reduce our downtime, manage the ISPs, and deploy SLAs for all the website traffic.

The most valuable feature of FortiGate is FortiView which provides proactive monitoring.

Functions like acting as an NTP server, DNS, DHCP, and auto-optimization mode enhance efficiency.
Director, Head of Networks at MUFG, EMEA
My actual traffic is around 2 GB, but I purchased a link from the ISP for only around 700 to 800 MB. All the prices that need to be paid monthly to the ISP are saved, which is a significant saving for my company after using Riverbed.

Vasu Gala - PeerSpot reviewer
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.
Chaudhary Muhammad Moez Manzar - PeerSpot reviewer
Senior manager at a tech services company with 201-500 employees
Reduces operational costs through bandwidth optimization but struggles with high traffic licensing and complex deployments
The logs in Steelhead are fantastic. There is a deep level of logs such as top 10 docker and top 50 docker. I can check from the top 50 docker which type of application is optimizing well and which type of traffic is not optimized. Steelhead provides logs and percentage levels, which is good. I can see any type of log report, report security, different types of report availability, but it is not customizable. Overall, this is a good feature. Steelhead provides real-time optimization with graphs and tables on real-time optimization, informing us packet by packet including port, source IP, destination IP, and destination port number. This reporting and real-time monitoring is fantastic, although I faced a problem in Oracle. Steelhead mainly saves the money that needs to be paid to ISPs. My actual traffic is around 2 GB, but I purchased a link from the ISP for only around 700 to 800 MB. All the prices that need to be paid monthly to the ISP are saved, which is a significant saving for my company after using Riverbed.

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…
