Fortinet FortiGate's support is effective and knowledgeable, though responsiveness and expertise vary by region and specific challenges.
Sentiment score
7.3
Barracuda CloudGen Firewall's customer service is accessible and knowledgeable, though support quality varies due to language and documentation issues.
Sentiment score
6.4
Many users rely on forums for support, expressing mixed satisfaction with OPNsense's accessibility, cost, and technical support.
I would rate their support for FortiGate a nine out of ten.
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.
Barracuda's partner support is better than the majority, and it stands out as one of their strengths.
The overall security has been satisfactory, with no breaches.
The technical support from Barracuda is very good.
I mainly rely on community support since the solution is open source.
 

Scalability Issues

Sentiment score
7.3
Fortinet FortiGate effectively scales with proper design, though complexities and hardware limits can arise, requiring accurate initial sizing.
Sentiment score
7.8
Barracuda CloudGen Firewall offers excellent scalability and management for various business sizes, though future capacity planning is advised.
Sentiment score
6.5
OPNsense is scalable for diverse organizations, efficiently supporting different user volumes, with some challenges in high-volume voice traffic.
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 positioning into customers, some larger enterprise customers tend to move towards one of the top three: either Cisco, Fortinet, or Palo Alto.
In my organization, there are 400 users, and OPNsense serves as our gateway and proxy for all of them.
Aside from these aspects, it demonstrated good scalability.
It supports routing, VPN setups, and traffic monitoring with additional packages like Snort and Suricata.
 

Stability Issues

Sentiment score
7.9
Fortinet FortiGate is reliable and stable with newer versions, requiring proper configuration to avoid minor glitches.
Sentiment score
8.2
Barracuda CloudGen Firewall is highly reliable and stable, with effective support and improved performance, despite minor bugs and past issues.
Sentiment score
8.5
OPNsense is stable with high ratings, despite issues with VPN failover, occasional bugs, and hardware compatibility concerns.
We have not had any problems with the operating systems or maintenance of subscriptions.
The solution is very stable.
We have observed that the device is significantly more stable than before.
We have very few issues with Barracuda Firewall, even in the case of zero-day vulnerabilities.
Version 8.0 had issues, but the newer version 9.0 seems to have improved performance regarding these issues.
Stability-wise, I rate the solution a ten out of ten.
It just doesn't respond, so I have to restart it over and over again to try to figure out what the problem is.
OPNsense is the same, but it does have a way of installing the Realtek drivers, which gives you a lot more stability overall on the system.
 

Room For Improvement

Fortinet FortiGate requires improved user interface, logging, compatibility, scalability, stability, VPN integration, and better documentation and support.
Barracuda CloudGen Firewall suffers from complex usability, unclear manuals, limited reporting, challenging licensing, high pricing, and VPN issues.
OPNsense faces challenges with integration, user interface, documentation, scalability, performance, and security features, needing enhancements in various areas.
If I have put 10 GBPS of throughput on a firewall and I enable all of these features available, such as IPS or UTM functionalities, the throughput comes down to 1 GBPS.
By providing an integrated solution, users would have access to all features and functionalities within a single window, eliminating the need to navigate through multiple windows.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
Integration with AI would be helpful as modern attacks often utilize AI.
It would be beneficial to merge the existing application policy with the main policy into a single unified policy to improve manageability.
Some licensing aspects are challenging; for example, if you're using an active-passive setup, you have to license both firewalls.
For high availability, it's crucial to have a method in place where a designated component oversees the entire process.
The user experience when we create policies can be made easier.
Some of the features include classified traffic and better blocking of newly registered DNS domains.
 

Setup Cost

Fortinet FortiGate is cost-effective compared to peers, with reasonable licensing costs despite initial setup fees and optional features.
Barracuda CloudGen Firewall is cost-effective with transparent licensing, offering significant savings and includes a four-year replacement program.
OPNsense is a cost-effective, flexible solution for enterprises, preferred over costly alternatives like FortiGate and Palo Alto.
The most expensive part is the renewal of the license subscription.
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.
The license price of Barracuda CloudGen Firewall is lower than others, and maintenance or support is included.
It is neither the cheapest nor the most expensive option available.
It's a free solution.
It is a free solution, and when you compare it to alternatives like FortiGate, which is quite powerful but also costly, the value becomes evident.
I would rate the pricing a nine out of ten, especially considering the availability of a free community edition.
 

Valuable Features

Fortinet FortiGate offers robust VPN, strong security features, user-friendly management, high scalability, affordability, and seamless integration capabilities.
Barracuda CloudGen Firewall offers robust security and seamless integration, ideal for efficient network management with advanced features and centralized control.
OPNsense is valued for its flexibility, user-friendly interface, robust features, frequent updates, and compatibility with useful plugins.

Strong security with effective traffic management and good support
The interface of Barracuda CloudGen Firewall is not as user-friendly as others. It is a bit complicated and could be improved. The initial setup can also be complex because it involves navigating different menus instead of a linear setup process. Integration with AI would be helpful as modern attacks often utilize AI.
RicardoDias - PeerSpot reviewer
A FreeBSD system that has a nice library of add-ons
The tool's deployment is easy. Apart from Cisco firewalls and Fortinet, if we talk about Untangle, pfSense, OPNsense, and so on, they are fairly quick to set up. It's not something you spend too much time on. It's a firewall, so you can spend months tweaking the system. If you know what you're doing, you can spend forever on logs, checking and tweaking the system because there's always a new update or feature coming up. Then you start playing with them, tweaking settings, checking logs, blocking or unblocking different things. You can stay in that loop forever. But for a startup, the initial configuration is fairly easy and quick. It can be completed in 30 minutes.
