| IT Security at a manufacturing company with 11-50 employees | 4.5 | I use Zscaler Cloud Firewall for remote access due to its customizable security policies, allowing users access only to specific resources. However, I'm considering Twingate for easier VPN configurations and improved network management visibility despite its current lack of a dashboard. |
| Cyber Security Architect at Accenture | 3.0 | As a solution architect, I found Zscaler Cloud Firewall beneficial for traffic forwarding and filtering on non-standard ports, offering consolidation of products. However, it requires improvements in its outdated GUI and lacks features available in competitors like Netskope and Palo Alto. |
| Deputy General Manager at Sagility | 4.5 | I use Zscaler Cloud Firewall to block non-standard traffic from our network, finding it effective in monitoring unwarranted activity. However, its understanding of dynamic cloud applications could improve for better adaptation to modern cloud environments. |
| Director at Aquila ICT Solutions | 4.0 | No summary available |
| Security Operations Centre Lead at Syngenta | 4.0 | I use Zscaler Cloud Firewall to secure internet services and appreciate its smooth configuration and management experience. However, Zscaler's marketing strategy lacks differentiation in product components, which could be improved for better product identification. |
| Network manager admin at Yamaha | 3.5 | I use Zscaler Cloud Firewall for internet filtering and traffic management in my company. It effectively blocks malicious traffic and offers centralized management globally, though it needs improvement in DC performance and should avoid using a proxy IP. |
| Sr.technical consultant at Navigator Systems Prt. Ltd. | 5.0 | I find Zscaler Cloud Firewall to be a complete cybersecurity solution with excellent firewall and VPN capabilities. However, its pricing is challenging for smaller organizations. We also utilize solutions like Mimecast, Akamai, Proofpoint, and Check Point. |
| Senior Consultant at OPTIV | 4.5 | In the review, I appreciate Zscaler Cloud Firewall's granular policy control, valuable visibility and log availability for troubleshooting, and high return on investment due to feature-rich offerings. However, the standard license lacks certain log insights compared to the premium version. |
