SonicWall TZ ensures rapid returns, blocking threats effectively, proving invaluable for small businesses, especially during the pandemic.
Clients are now comfortable and not wasting productive hours on IT support.
The automation part is giving us a cost benefit and speed; we can react faster.
It's a very useful tool to mitigate and protect your enterprise.
That is a reason to buy a firewall, and it is challenging to put a monetary value on security.
 

Customer Service

Sentiment score

Fortinet FortiGate's customer service is praised for strong support but experiences inconsistent response times and varying support quality.

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.
Customer service is excellent.
 

Scalability Issues

Sentiment score
7.3
Fortinet FortiGate is scalable and flexible, though complex deployments and upgrade costs can pose challenges for users.
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.
 

Stability Issues

Sentiment score
7.9
Fortinet FortiGate is praised for stability and performance, with timely updates enhancing reliability in diverse configurations.
Sentiment score
7.6
SonicWall TZ is highly reliable and stable, though minor issues occur under heavy use or after updates.
We're experiencing 99.999% availability consistently.
I would rate the stability of Fortinet FortiGate a ten out of ten.
We have not had any problems with the operating systems or maintenance of subscriptions.
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 find issues with support, cost, usability, and features like DLP and reporting compared to competitors.
SonicWall TZ needs an improved interface, reporting, security features, and more efficient support, licensing, and advanced options.
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.
The constant daily revisions necessitate meticulous identification of the relevant documents to prevent the use of outdated information that could jeopardize our environment.
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 cost-effective pricing for SMBs, with manageable upfront costs and negotiable long-term discounts.
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.
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.
 

Valuable Features

Fortinet FortiGate offers comprehensive security features, easy management, high-performance support, and competitive pricing, making it highly valued by users.
SonicWall TZ offers user-friendly management, robust security features, and scalability, making it ideal for small to medium enterprises.
The firewall, IPS, and VPN functions are the most valuable features.
FortiGate provides solid protection against viruses, malware, and other threats.
In terms of security, we have not experienced any security flaws or loopholes, and it has proven to be quite stable.
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.

Featured Reviews

Jorge Martínez - PeerSpot reviewer
Offers good SD-WAN capabilities and integrates easily with Fortinet devices
I am not part of the initial setup or deployment process since I work in presales. The setup or deployment is quite easy, as you can do a one-touch deployment that automatically connects to the FortiManager cloud when you connect it to a broadband or dynamic IP, allowing you to start the configuration from that point. We usually sell it for on-premises setups. It's on the cloud only when the client has virtual machines or their own service. Sometimes they have a service on the cloud like AWS, but it's more difficult to sell now because AWS has an e-commerce option where you can buy FortiGate directly. The only thing you need is someone to manage and configure.
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.

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…
