Scalability Issues

Sentiment score
7.0
Fortinet FortiGate is scalable, adaptable for business needs, but requires advanced planning to avoid hardware and licensing issues.
Sentiment score
8.6
Fortinet FortiOS offers scalable solutions for varying business sizes, though some hardware upgrades may be needed for expansion.
Sentiment score
7.5
Juniper SRX Series Firewall is scalable and popular among businesses, but faces clustering issues and tough competition.
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.
When customers' networks grow and needs expand, we can easily switch between models to trade up devices.
It allows for the expansion of users and devices without additional licensing costs.
Fortinet FortiOS is scalable, allowing the addition of users and firewalls as required.
 

Stability Issues

Sentiment score
7.5
Fortinet FortiGate is praised for its stability and performance, though some models face issues with high traffic.
Sentiment score
7.5
Fortinet FortiOS is stable and reliable, outperforming alternatives, with any issues mainly due to configuration challenges.
Sentiment score
8.4
Juniper SRX Firewall is stable and reliable, but proper configuration is crucial for maintaining performance under demanding conditions.
We're experiencing 99.999% availability consistently.
I would rate the stability of Fortinet FortiGate a ten out of ten.
Currently, we are experiencing a general outage of one of the main internet service providers of the Dominican Republic, and we have not been impacted in our operations because with SD-WAN, we have another internet service provider and we are working with the second WAN connection without any disruption.
While the product is largely stable, it sometimes faces memory issues in specific versions like 11 OE, which can be disruptive.
Stability is a seven out of ten because during version migrations, and sometimes with new versions, Fortinet is not as good.
I would rate the stability of FortiOS as an eight out of ten.
The solution has absolutely high stability.
 

Room For Improvement

FortiGate needs improvements in interface stability, user experience, reporting, VPNs, licensing costs, documentation, performance, and support.
Fortinet FortiOS users want improved usability, better management, enhanced security features, and more efficient support, especially for 60D models.
Juniper SRX Series Firewall needs improvements in user interface, interoperability, scalability, support, and lacks next-gen security features.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
While Fortinet claims to offer a comprehensive network solution, it falls short in addressing computer application issues, particularly server security.
When considering Sophos XG, which we also use, the logging and reporting functionality is notably more efficient.
Fortinet FortiOS faces memory issues, which can lead to unexpected downtimes.
There should be more documentation on how to use the CLI or how to perform CLI versions of tasks that can be done through the GUI.
Compared to other market leaders like Palo Alto and Check Point, FortiOS has many bugs in its initial releases.
With a better user interface and graphical interface, the Juniper SRX Series Firewall could be a superior solution compared to what it is now.
With my extensive experience with the Juniper SRX Series Firewall, the robustness of the SD-Cloud or Security Director interface and overall functionality needs to be improved to compete with leading firewall solutions.
 

Setup Cost

Fortinet FortiGate is valued for cost-effectiveness, clear licensing, but renewal costs can vary compared to competitors.
Fortinet FortiOS pricing is moderate and scalable, with renewal costs potentially high despite competitive initial bundling offers.
Juniper SRX Series Firewall provides competitive pricing with high performance, although advanced features and support may incur additional costs.
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.
The advantages of Fortinet FortiGate over its competitors include good pricing and meeting our requirements at a lower cost.
It is an affordable solution for us.
Fortinet products are somewhat pricey, similar to Cisco equivalents, however, they have justified their price point.
I am satisfied with the pricing, licensing, and setup costs of FortiOS, rating it nine out of ten compared to other familiar leading firewalls.
The Juniper SRX Series Firewall is affordable and cost-effective.

Featured Reviews

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.
Harshama Silva - PeerSpot reviewer
We have improved network security with user-friendly controls and high threat intelligence
FortiOS is very user-friendly and easy to configure for L1, L2, and L3 personnel. Its web filtering, application control, and IPS features are very user-friendly, easy to manage, and deploy. The threat intelligence in FortiOS is very high, and the system is scalable without additional licensing costs. FortiOS allows us to expand the number of users and devices as our network needs grow.
Chinedu Onwurah - PeerSpot reviewer
Robust security measures and cost-effectiveness meet diverse industry needs
The biggest benefit of Juniper SRX Series Firewall overall is that it is rugged and cost-effective, offering basic firewall features and additional licensed features as needed. The main challenge I see as a distributor is Juniper's rating in the Gartner report, where Juniper is not a leader in enterprise security, which often influences customer conversations. Most customers want to check the Gartner report before they engage, making it challenging to sell Juniper security. With my extensive experience with the Juniper SRX Series Firewall, the robustness of the SD-Cloud or Security Director interface and overall functionality needs to be improved to compete with leading firewall solutions.
