Valuable Features

SonicWall TZ is praised for its robust network security, ease of use, and affordability. Users appreciate features like content filtering, VPN functionality, intrusion prevention, SD-WAN integration, and deep packet inspection. The system's interface is user-friendly, making setup and management straightforward. It effectively handles site-to-site and remote access VPNs, providing strong threat prevention capabilities. It is beneficial for small enterprises due to its reliable performance, real-time threat detection, and extensive security controls.
  • "Whatever is required for my organization, the TZ 400 has performed admirably."
  • "It does what it says it is going to do."
  • "We like the central interface and we like the security features; additionally, we use SonicWall with VPN connectivity and we have had no problems with SonicWall all these years."

Room for Improvement

SonicWall TZ requires enhancements in user interface, threat intelligence, and reporting tools. The GUI and configurations are not intuitive, leading to difficulties in setup and navigation. Improvement is needed in scalability, pricing, and integration with other platforms. VPN licenses are limited and should be included in the main package. Additionally, support services should improve, and features like advanced logging, content filtering, and site-to-site VPN setups need refinement.
  • "The interface and technical support are probably the two most important things that I would like SonicWall to improve."
  • "The user support could be improved because you have to go outside and get that kind of support."
  • "In the next release, I would like to see a SonicWall integration with the DLP tool, this would be interesting."

ROI

SonicWall TZ delivers immediate return with low management costs and enhanced security. Users experience average returns in eight months and note significant security improvements. It's a cost-effective choice for small businesses, often considered worth the investment without apparent loss. High intrusions security is reported with effective threat prevention. While older units require upgrades, SonicWall TZ operates effectively. ROI remains hard to measure because the benefits are mostly preventative, proving its worth in maintaining security.

Pricing

Enterprise users report that SonicWall TZ offers a competitive a la carte pricing model, allowing flexibility by paying only for desired features. However, the yearly subscription fee can add up, potentially making it costlier over time compared to competitors. Licensing generally renews annually and includes standard support, but additional options like advanced security features may incur extra costs. The solution is often viewed as moderately priced, with its cost-effectiveness varying by features and support required.
  • "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 utilized for firewall protection, VPN connections, and network security. It is favored by small to medium-sized organizations due to its affordability and ease of deployment. Many users employ it for site-to-site VPN, content filtering, and unified threat management. It supports remote access, application control, and provides comprehensive security features like intrusion prevention, antivirus, and application filtering, making it suitable for securing various business environments.

Service and Support

SonicWall TZ customer service is frequently praised, though some note long hold times. Technical support is generally knowledgeable and efficient, yet experiences vary. Some users highlight language barriers and a need for more prompt service. Others commend support for its expertise and helpfulness, with high ratings from many. Multiple licenses offer 24/7 support options, while level two and three support tends to be more competent compared to initial contacts.

Deployment

SonicWall TZ's initial setup is mostly described as straightforward with helpful wizards, making it easy for technical teams. Deployment time can vary based on complexity and size of the organization, ranging from 10 minutes to a few hours. While some find the interface challenging, others note it takes one person for deployment. Larger configurations might require assistance or additional time, especially when integrating advanced features or handling intricate environments.

Scalability

SonicWall TZ's scalability is good for small to medium organizations, but not ideal for larger entities. It's often necessary to select the proper model upfront to avoid limitations. While it offers flexible licensing and modular options, it struggles with significant user count increases. Some find its capacity restricted, especially regarding bandwidth and connections. Proper model choice initially helps ensure efficiency in scaling within its physical constraints.

Stability

SonicWall TZ is generally stable with occasional minor issues and crashes. It performs well with up to 100 users, although higher demands can challenge its performance. Some encounters with VPN slowness and rare reboots were reported, yet many users find it reliable, stable, and recommendable. Recent updates have improved its VPN connectivity, ensuring better performance. SonicWall TZ stability is frequently rated between seven and ten out of ten.

SonicWall TZ Reviews Summary
Author infoRatingReview Summary
Senior Pre-sales and Solutions Engineer - Cyber Security at Enterprise Technology (Pvt) Ltd3.0I recommend SonicWall TZ for SMBs needing a budget-friendly, easy deployment firewall with solid web filtering, DPI, SD-WAN load balancing, and monitoring. However, its threat intelligence, ML detection, GUI, documentation, scalability, and support lag competitors; stability has minor issues.
Project Engineer at IT Solution4.5I use SonicWall TZ for WAN‑to‑LAN filtering, NAT, and security with IPS/IDS/ATP plus content and application filtering. It’s stable, scalable, and support is good; it blocks threats and attacks. My main issue is paid VPN licensing.
CEO at Kapstone Technological Services LLP4.5I've used SonicWall TZ for over 14 years; it's easy to deploy, stable, scalable, and ideal for small businesses. The SSL VPN is great for remote work, though support could improve and performance should remain strong as features grow.
CTO at Exceed NetSec LLC3.5We implement SonicWall TZ alongside various other products based on client requirements. While SonicWall offers valuable VPN functionality and stability for SMBs, it falls short in dynamic DNS services and integration with other vendors, especially in VPNs.
Administration IT at a engineering company with 11-50 employees4.5I primarily use SonicWall TZ in my office to secure our network and support remote work during COVID. Its reliable performance and VPN capabilities are valuable, though I am considering upgrades due to outdated technology and exploring other options like Sophos.
Technical Associate at VSecure Networks4.0I've used SonicWall TZ primarily for firewall protection, SD-WAN, and SSL VPN for remote access. The ease of policy creation and effective security features stand out, though improvements are needed in SSL VPN licenses and simplifying DNAT and port forwarding configurations.
Chief Technology Officer at Nexa SecureIT4.5I use SonicWall TZ for firewalls, and I find its VPN functionality rock solid and user-friendly. However, I would like to see SD-WAN and content filtering features added. An agent on user laptops for site blocking would be beneficial.
Server & Cloud Architect at Icare4.0I use SonicWall TZ for VPN connections and user access control, enhancing web filtering and port configurations. However, generating reports requires additional licenses, hardware flexibility is limited, and the cost of large-scale firewalls could be lower.
