6.5

Sentiment score
8.6
SonicWall TZ offers suitable scalability for small to medium businesses, but model selection is crucial for future growth planning.
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.

Room For Improvement

Fortinet FortiGate needs improvements in stability, support, integration, pricing, performance, cloud features, automation, and documentation clarity.
SonicWall NSa faces usability, performance, and support issues, with high costs and integration challenges impacting overall satisfaction.
SonicWall TZ needs an improved interface, reporting, security features, and more efficient support, licensing, and advanced options.
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.
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 pricing, straightforward licensing, and a strong price-to-performance ratio, appealing to small and medium businesses.
SonicWall NSa provides cost-effective security with competitive pricing, subscription-based licensing, and value-added features compared to competitors.
Buyers find SonicWall TZ pricing competitive but potentially high due to additional subscription and licensing fees, affecting affordability.
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.
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 offers robust security, user-friendly management, and flexibility, with comprehensive VPN and advanced threat protection features.

SonicWall NSA's most valuable features are its SD-WAN and a system RTBI that blocks all attacks.
For SMB segments, SonicWall performs well.
It was beneficial during COVID for remote work through its VPN functionality.
The advanced gateway security features such as web filter, application control filter, IPS, ideas, gateway antivirus, anti-spyware, and botnet filter are valuable.

Ensures business continuity with reliable internet connectivity and robust security features
The content filtering and URL filtering capabilities, along with packet content filtering, are very good. It helps us restrict internet traffic during working hours to legitimate work-related traffic. Workers are only able to access social media, YouTube, and similar sites after work hours. It helps in protecting the edge significantly because we are able to determine what must be accepted and what must not be accepted. We also have FortiAnalyzer, which is the log analyzer for Fortinet FortiGate. Being AI-driven, it helps us see what is happening and new emerging threats quickly. We are able to make the necessary interventions to protect the network. We are using QRadar as a SIEM, and Fortinet FortiGate integrates with it seamlessly. FortiAnalyzer picks all logs from Fortinet FortiGate, integrates with QRadar, and allows us to see everything. It also integrates beautifully with our EDR from WithSecure. It also helps reduce power consumption. Fortinet FortiGate is a greener listing in terms of power consumption.

Robust VPN integration stands out despite needing enhanced vendor compatibility
The integrated VPN functionality is working well with the global VPN client, which is a fast client, though it comes at a cost. SonicWall TZ is functional depending on the service level taken by the user. For SMB segments, SonicWall performs well. Despite lacking certain features, it is still considered a good product. The appliance itself is functional and stable, offering integrated solutions.

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…
