Zscaler Internet Access and Kaspersky Security for Internet Gateway compete in the internet security gateway category. Zscaler has the upper hand due to its comprehensive range of security features that offer a robust solution for organizations.
Features: Zscaler Internet Access provides URL filtering, malware and threat protection, and cloud sandboxing. Additionally, it has an advanced firewall and seamless SSL inspection, which enhances protection against zero-day malware. On the other hand, Kaspersky Security for Internet Gateway focuses on its antivirus capabilities, ease of use, and effective threat detection.
Room for Improvement: Zscaler Internet Access could improve in application integration, ease of reporting, and intuitive exception management.

Reviews from Real Users
Below are some reviews and helpful feedback written by Zscaler Internet Access users.
A Service Manager at a construction company says, "There are a bunch of different capabilities that are valuable within the platform. We use quite a lot of them, but not everything. The ones that are most important to us are the URL Filtering and the application control. For our needs, the cloud-native proxy architecture is a very good solution. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."
Owen N., Security Architect at Claro Enterprise Solutions, explains that the solution’s most valuable features include “The integration of the gateway that inspects all ports and protocols. So, there is threat prevention; The cloud sandbox; VNS security; Access control that will protect URL filtering and the cloud firewall; Data protection that will protect your gateway, like your CASB or your cloud DLP; The capabilities of this will point your traffic to Zscaler Cloud.”
An Architecture Senior Manager at an insurance company mentions, "The data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go." He also adds, “The solution provides quick access to cloud services, securing our data and allowing us to inspect all our traffic.”
