Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
7.5
Fortinet FortiGate is valued for affordability, cost savings, enhanced security, operational efficiency, quick implementation, and long-term ROI benefits.
Sentiment score
7.2
FortiGate Next Generation Firewall provides effective security and control, though opinions differ on financial returns and cost-effectiveness.
Sentiment score
7.4
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.
There's definitely an ROI. Having a centralized way of managing and applying policies across the entire organization always helps.
It has notably improved our efficiency and visibility.
Using FortiGate has enabled us to increase security, control user access, manage bandwidth, and enhance the ability to provide a variety of operations solutions to clients.
It's easy to configure a new connection, and it works in a few minutes if everything works fine.
That is a reason to buy a firewall, and it is challenging to put a monetary value on security.
 

Customer Service

Sentiment score
7.0
Fortinet FortiGate's customer service is praised for strong support but experiences inconsistent response times and varying support quality.
Sentiment score
6.4
Customer support for FortiGate NGFW is generally positive, with responsive teams but occasional delays and room for improvement.
Sentiment score
5.4
SonicWall TZ customer service varies; some praise efficiency and competence, while others note slow response and communication issues.
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.
I must study the best version to install to avoid previously found bugs.
In some cases, you need to come prepared because the people there work by the book and ask for particular things. If you don't have them, you cannot proceed, but if you know what they need, after some time, it's pretty easy to get support or whatever you need.
FortiGate offers good support.
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
7.6
FortiGate NGFW is effective for businesses of all sizes but faces scalability and cost challenges for larger enterprises.
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.
What it allows us in terms of connections to other companies is a straightforward solution that you don't have to use something else.
 

Stability Issues

Sentiment score
7.9
Fortinet FortiGate is praised for stability and performance, with timely updates enhancing reliability in diverse configurations.
Sentiment score
8.2
FortiGate Firewall is stable and reliable, scoring high post-5.6, with minor firmware update and UI issues.
Sentiment score
7.6
SonicWall TZ is highly reliable and stable, though minor issues occur under heavy use or after updates.
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.
In some cases, you need to restart it, but mostly, it's working flawlessly, especially if you have an HA environment, high availability.
In my experience, there are usually no significant stability issues with FortiGate Next Generation Firewall (NGFW).
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.
FortiGate NGFW requires improvements in user-friendliness, integration, support, costs, and compatibility, with enhancements needed in key features.
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.
Improvements could be made when companies expand and need better equipment and more licenses.
Configuring these services is quite complex and not very user-friendly, requiring technical steps that are difficult for normal users to understand.
When a site is blocked, it is necessary for me to consult the logs to understand what the Next Generation Firewall policy has blocked.
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.
Enterprise users find FortiGate NGFW pricing competitive, more affordable than Cisco but pricier than Sophos, with additional feature costs.
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.
It offers cost savings as it is generally cheaper than the competition.
The pricing of FortiGate Next Generation Firewall is competitive.
Fortinet tools like FortiGate are costly for us as a higher education institute in India.
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.

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.
Juan Solano - PeerSpot reviewer
Implementation improves efficiency and provides greater visibility over issues
One of the most valuable features of FortiGate Next Generation Firewall (NGFW) ( /products/fortigate-next-generation-firewall-ngfw-reviews ) is the ease of usability it offers. It is quite easy for me to learn to use. Additionally, FortiGate Next Generation Firewall (NGFW) has improved our efficiency in setting up security and provided us with more visibility over some issues and incidents we previously faced.
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.
