That is a reason to buy a firewall, and it is challenging to put a monetary value on security.

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.

Sentiment score
6.7
SonicWall NSa scalability is largely praised, with adaptability depending on model and workload expectations, requiring potential upgrades.
Sentiment score
7.1
SonicWall TZ suits small to mid-sized businesses but planning and model choice are key for extensive scalability.
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.
I would rate its scalability around eight out of ten, meaning there are no issues, and it is pretty easy to scale.
Regarding scalability, it's important to ascertain the customer's future requirements, as firewalls need to be sized according to their expected scalability, such as moving from 500 users today to more in the coming years.

Sentiment score
7.4
FortiGate is praised for stability and performance, with minor challenges managed by updates, proper sizing, and support.
Sentiment score

6.3
SonicWall TZ is praised for reliability and security, though occasional minor issues and update disruptions may occur.
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.
The stability of SonicWall NSA is quite good.
In terms of stability, SonicWall doesn't have performance issues.
SonicWall TZ rates 10 out of 10 for stability.
SonicWall TZ is definitely stable and offers a good value for money.
 

Room For Improvement

Fortinet FortiGate struggles with integration, user complexity, support inefficiencies, high costs, and feature performance, needing improved documentation and security.
SonicWall NSa's complex interface and inadequate features hinder usability, leading to delays and inefficiencies in management and troubleshooting.
SonicWall TZ needs interface, reporting, and support improvements, while high pricing and complex licensing affect user satisfaction.
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.
More details in the analytical tools offered would be appreciated since it is not yet mature.
There are some aspects of the dashboard configuration or customization that could be improved.
Integration with other vendors, especially with VPNs, can be challenging and requires more effort when configuring.
SonicWall TZ could benefit from newer technology.
The VPN license should be improved by providing more free SSL VPN licenses.
 

Setup Cost

Fortinet FortiGate offers competitive, cost-effective pricing, appealing to small-medium businesses with flexible licensing and valued security solutions.
SonicWall NSa is cost-effective for enterprises with competitive pricing, appealing licensing, and potential savings on maintenance.
SonicWall TZ's flexible pricing and upgrade promotions offer competitive, cost-effective solutions for small to medium enterprises despite setup 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.
SonicWall is much cheaper compared to Fortinet, particularly regarding renewal and licensing costs.
I would rate the price of the product as seven out of ten.
More licenses are required to purchase the perpetual license for SSL VPN and Global VPN.
When comparing similar products across vendors, there may be a small difference in cost.
I would also position its pricing as a three, where one is the lowest price and ten is the highest.

SonicWall NSa provides comprehensive network security with deep packet inspection, UTM features, scalability, and user-friendly management for businesses.

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.

Provides reliable performance with strong features and simplicity
SonicWall TZ is user-friendly, admin-friendly, and a beautiful product. I have been selling SonicWall since 2007 without any issues. SonicWall has been working on it excellently. They are up to date, and their research team is good, making the box feature-rich. Based out of India, I have had some issues with their faulty channel policy. It's a very good product, an awesome product for those who want to use SonicWall TZ. You can bet on it, but check out the channel policies in India. They should check out the channels in the channel business. It's just a precaution, nothing more than that. Overall rating: 9 out of 10.

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…
