Key learnings from peers

Valuable Features

It excels in VPN functionalities for site-to-site and remote access. Users appreciate its user-friendly interface, content filtering, integration, and high throughput. SonicWall TZ provides robust threat prevention, intrusion protection, and application controls. It supports high availability, scalability, and effective policy creation, making it ideal for various network security needs.
  • "The advanced gateway security features such as web filter, application control filter, IPS, ideas, gateway antivirus, anti-spyware, and botnet filter are valuable."
  • "Customer service is excellent."
  • "SonicWall TZ offers security and easy firmware updates."

Room for Improvement

SonicWall TZ requires improvements in mail security, application detection, reporting, and support. The interface needs to be more intuitive and user-friendly. Features like advanced malware analysis, content filtering, and robust DNS services should be enhanced. Virtual UTM models, centralized management, scalable solutions, and better licensing options are also required. Performance issues with throughput and SSL inspection need attention, while pricing could be more competitive. Additionally, better integration with other platforms should be considered.
  • "The VPN license should be improved by providing more free SSL VPN licenses."
  • "SonicWall TZ could benefit from newer technology. That is why I am looking to upgrade and researching other solutions."
  • "SonicWall TZ could benefit from newer technology."

ROI

SonicWall TZ provides immediate ROI and enhances security at a low management cost. Users report increased productivity, with many seeing ROI within eight months. It is praised for its comprehensive features suited for small businesses, offering protection against intrusions and maintaining network safety. Although upgrades may be necessary, many find it worth the investment, akin to essential utilities like air and electricity. The ROI is often described as intangible due to prevention of potential losses.

Pricing

SonicWall TZ's pricing is seen as competitive, offering a la carte features that can minimize upfront costs. However, users note the annual licensing fees can accumulate, potentially making it pricier than competitors like WatchGuard. Setup involves hardware costs but is streamlined through authorized distributors. License renewals pose challenges in some regions, and the need for additional licenses for management can increase costs. While some find the price reasonable, others see it as high, highlighting the balance between cost and features.
  • "The product pricing is justified for the features provided."
  • "The firewall with the servers costs about 80 pounds a month. We get the device, and it is replaced every two or three years."
  • "The solution is moderately priced, where it's neither cheap nor expensive."

Popular Use Cases

SonicWall TZ is primarily used for network security, including firewall protection, VPN connectivity, and threat management. It supports remote access for building solutions, content filtering, and anti-virus management. Businesses, schools, and service providers utilize it for protecting networks, ensuring connectivity across branches, and filtering internet access. They employ it for user access control, web filtering, and securing internal and external network communications.

Despite some mixed experiences, many find the support adequate and competent.

Deployment

SonicWall TZ's initial setup is typically straightforward and quick, often aided by wizards. Many find it easy, taking anywhere from 10 minutes to a couple of hours. Those with extensive network configurations experience more complexity, requiring adjustments and longer deployment times. Experienced users can configure it more efficiently, while newcomers might find the interface initially challenging. Complexity increases with additional features and settings, affecting deployment duration, which depends on user requirements and network size.

Scalability

SonicWall TZ's scalability is satisfactory for small to medium-sized organizations. Its modular structure allows tailored configuration, although upgrades beyond device limits require new hardware. Users appreciate its ease of use and flexibility within its capacity, but it can be costly. Many note the importance of selecting the right model from the start to avoid future constraints. Licensing flexibility is suggested for larger enterprises when user counts surpass initial expectations.

Stability

SonicWall TZ is largely stable, performing well without frequent crashes or freezes. While some users report minor issues, such as VPN connectivity or occasional glitches, most find it reliable, with few requiring frequent reboots. Despite past acquisitions causing market confusion, users rate its stability highly, often nine or ten out of ten. Generally, SonicWall TZ maintains consistent performance, though its stability may diminish with increased operational demands or extensive user numbers.

Robust VPN integration stands out despite needing enhanced vendor compatibility

Pros

"For SMB segments, SonicWall performs well. "

Cons

"SonicWall should incorporate dynamic DNS services to eliminate the need for third-party solutions, particularly for environments using dynamic IP addresses. "

What is our primary use case?

We are working on various projects, not limited to Fortinet. We implement multiple products based on client requirements. We deal with different projects on a project-by-project basis as we are a solution-based company. We also manage mail archiving and Docker solutions.

What is most valuable?

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.

A firewall solution with solid VPN

Pros

"The VPNs are rock solid. I never have an issue with them. We also have rules to block encrypted traffic to specific sites and geolocations. The integrated VPN functionality is easy to use. "

Cons

"I expect to see SD-WAN in the tool's next release. The product should implement a content filtering feature. You need to put an agent on the user's laptop device. It would enforce security policies and block sites even if they were off-site. You can block sites from network sites. "

What is our primary use case?

We use the solution for firewalls.

Has efficient user access control feature and good technical support services

Pros

"The product is easy to deploy."

Cons

"We encounter issues while generating new reports. "

What is our primary use case?

We use the product for VPN connections. It allows establishing rules for user access control, specifying which types of websites and resources they can access. It defines restrictions for specific IPs. It helps us with web filtering templates, including white listings, black listings, and port numbers. We can configure port forwarding to allow specific services or applications like video and audio communications devices to be accessed outside the network. It involves configuring multiple ports to accommodate various types of use cases.

What needs improvement?

We encounter issues while generating new reports. We have to buy an extra license for it. There could be a subscription management feature. Along with this, the cost of large-scale firewalls could be reduced. There needs to be flexibility in terms of hardware. We should be able to implement and install external software on hardware, such as VMware or HP servers, etc.

What is our primary use case?

Currently, I am using SonicWall TZ to connect our branches to the head office. We use it as a site-to-site VPN.
