Lookout’s mobile EDR solution goes beyond traditional endpoint solutions by addressing the unique architecture, behaviors, and risks of iOS and Android devices. It provides industry-leading mobile threat defense on employee devices while also granting security teams the visibility and actionability needed to align mobile risk with traditional endpoint risk. By leveraging the world's largest AI-driven mobile security dataset, Lookout utilizes artificial intelligence (AI) and behavioral analysis to detect threats before they escalate, ensuring comprehensive protection for sensitive data and enabling secure mobile productivity.
Recognizing that employees using mobile devices are the new frontline, attackers are increasingly employing sophisticated social engineering techniques like phishing and smishing. These tactics exploit basic human instincts—trust, curiosity, and urgency—to trick users into revealing sensitive credentials, allowing threats to bypass traditional legacy security solutions. To combat this, Lookout provides AI-first protection against advanced social engineering attacks, device compromises, vulnerabilities, mobile malware, network threats.
Zscaler Internet Access is a cloud-native security service edge (SSE) platform. Its main purpose is to provide AI-powered protection for all users, all applications, and all locations. The solution replaces other legacy network security solutions to stop advanced attacks and prevent data loss by using a comprehensive zero trust approach.

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.”
