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

6.5
SonicWall NSa offers scalable options and manageable costs, though some find hardware upgrades and configurations challenging.
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.

I would rate the stability of Fortinet FortiGate a ten out of ten.
The solution is very stable.
The stability of SonicWall NSA is quite good.
In terms of stability, SonicWall doesn't have performance issues.
SonicWall TZ is definitely stable and offers a good value for money.
 

Room For Improvement

Fortinet FortiGate users seek improvements in stability, integration, scalability, cost, and advanced features like monitoring and zero-trust technology.
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.
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The constant daily revisions necessitate meticulous identification of the relevant documents to prevent the use of outdated information that could jeopardize our environment.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 various licensing models, balancing affordability and performance, though renewals can increase costs.
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.
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 offers robust security, user-friendly management, and flexibility, with comprehensive VPN and advanced threat protection features.

In terms of security, we have not experienced any security flaws or loopholes, and it has proven to be quite stable.
FortiGate has helped reduce the risk of cyberattacks that might disrupt our client's production.
These features help reduce our downtime, manage the ISPs, and deploy SLAs for all the website traffic.
Real-time deep memory inspection is very helpful and has had a positive impact on our security posture.
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.

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.

Network security has strengthened with next-generation firewall features and cost savings
I primarily use SonicWall NSA as a next-generation firewall for network security architecture. It is especially used for securing business operations with networks of more than 250 people SonicWall NSA's most valuable features are its SD-WAN and a system RTBI that blocks all attacks. These…
Rias Majeed - PeerSpot reviewer
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.

Basically, the main difference is that the TZ series is intended for a Branch office since it has fewer ports and the speed is around 1 GB. The NSA series has more processor power and more port where you can create subnets and zones (like DMZ). Also, it has ports with 10 Gb and a processor to support the demand. I have read that an approximate number of users in the highest TZ series (TZ 670)...

Basically, the main difference is that the TZ series is intended for a Branch office since it has fewer ports and the speed is around 1 GB.  The NSA series has more processor power and more port where you can create subnets and zones (like DMZ). Also, it has ports with 10 Gb and a processor to support the demand.  I have read that an approximate number of users in the highest TZ series (TZ 670) is around 150 to 200 but that is just an estimate.  Hope this helps. You can get more details in SonicWall datasheets where you will find the speed, throughput and more technical specifications to select the one that fits your requirements.

In simple words, TZ is for small businesses (less than 100, maximum 150 users).  TZ has fewer ports. NSA is for medium and large enterprises: > 150 Users,  NSA has many ports to support large networks
