    Trusted cloud security solutions

    Reviewed on Jul 10, 2026
    Review provided by G2
    What do you like best about the product?
    What I like most about Zscaler Internet Access is its cloud-native, Zero Trust approach to securing internet access. It provides secure, policy-based access from any location without relying on traditional VPNs. Features like URL filtering, SSL inspection, cloud firewall, and centralized policy management improve security, simplify administration, and enhance visibility while delivering a seamless user experience.
    What do you dislike about the product?
    One drawback of Zscaler Internet Access is that troubleshooting can be challenging because traffic is inspected and routed through the cloud, making it harder to quickly identify the root cause of connectivity issues. SSL inspection may also cause compatibility issues with some applications if not configured properly. Additionally, creating and managing complex policies requires a good understanding of the platform, and policy changes can sometimes take time to validate and test. Overall, these are manageable with proper planning and administration.
    What problems is the product solving and how is that benefiting you?
    Zscaler Internet Access solves the challenge of securing internet access for users regardless of their location. It replaces traditional perimeter-based security with a Zero Trust model, protecting users from malware, phishing, and unauthorized access while enforcing consistent security policies. For me, it simplifies security management, improves visibility into internet traffic, reduces reliance on VPNs, and helps resolve issues faster through centralized monitoring and detailed logs.

    Secure VPN Access Anywhere, on Any Network

    Reviewed on Jul 08, 2026
    Review provided by G2
    What do you like best about the product?
    What I like most is how it connects on any non-office network, no matter where I am. Anywhere I have an internet connection, I can connect to the VPN network safely and securely, which is one of its key USPs.
    What do you dislike about the product?
    Sometimes if the network is not good there, I feel some latency and video calls do buffer where without connecting this buffering will be less. This is prominent when more people are using this.
    What problems is the product solving and how is that benefiting you?
    Accessing sensitive data from non office networks like ARIBA, SAP, COUPA and legal platforms like Volody. These are very sensitive websites and joining them without being connected to office network is a plus point.

    Fast, Frictionless Direct-to-CloThe Ultimate Cure for Legacy VPN Latency

    Reviewed on Jul 07, 2026
    Review provided by G2
    What do you like best about the product?
    What I like best about Zscaler Internet Access (ZIA) is how it delivers exceptional performance through fast, direct-to-cloud connectivity and seamless SSL decryption, all while remaining virtually invisible to employees via a lightweight, frictionless end-user UI/UX. The platform features robust, ecosystem-wide integrations with our existing IdP and EDR tools (such as Okta and CrowdStrike), allowing us to seamlessly leverage ZIA's advanced AI and threat intelligence for proactive zero-day sandboxing and automated data protection. While the initial onboarding and support phase requires strategic planning to transition away from legacy routing, ZIA's premium pricing ultimately delivers a massive ROI by completely consolidating our security stack, eliminating costly hardware maintenance, and drastically reducing administrative overhead.
    What do you dislike about the product?
    What I dislike most about Zscaler Internet Access (ZIA) is the steep learning curve and fragmented nature of the admin UI/UX, which makes complex policy management cumbersome. While its security capabilities are strong, the deep SSL inspection frequently breaks proprietary or legacy applications, requiring tedious configuration bypasses that impact operational performance. Additionally, the initial onboarding is highly complex, and standard customer support can be slow to resolve intricate routing issues. Finally, ZIA sits at a very premium pricing point; the licensing feels rigid, and advanced AI and threat intelligence modules require expensive add-on tiers, making the total cost of ownership quite high."
    What problems is the product solving and how is that benefiting you?
    Zscaler Internet Access solves the core problems of legacy VPN latency and physical hardware sprawl by moving enterprise security entirely to a cloud-native edge. Instead of backhauling traffic through a traditional data center, ZIA routes our hybrid workforce directly and securely to the internet and SaaS apps. This benefits our organization by eliminating expensive appliance maintenance and drastically reducing IT administrative overhead through tool consolidation. Most importantly, its ability to perform 100% SSL decryption and AI-driven threat inspection at scale ensures we block zero-day attacks and prevent sensitive data leaks via shadow IT, all without sacrificing network performance for our end users.

    Centralized Cloud Management That Simplifies Day-to-Day Administration

    Reviewed on Jul 07, 2026
    Review provided by G2
    What do you like best about the product?
    However, the best thing about it is the centralized cloud management. It eliminates the need to maintain and scale any on-premises security appliances. Having everything managed globally through a single console is extremely efficient and makes day-to-day administration much simpler.
    What do you dislike about the product?
    At times, troubleshooting can be challenging because the logging process isn’t always instantaneous. For example, if a user gets blocked from accessing a site, having to wait for the traffic logs to appear on the dashboard to understand why the user was blocked can take a while.
    What problems is the product solving and how is that benefiting you?
    Problem: The cost of managing on-site firewalls and web proxies across multiple office locations was high, and it also led to fragmented security policies.

    Benefit: After implementing web security in the cloud, there is no longer a need to purchase, deploy, and maintain hardware infrastructure. As a result, no matter which office location is being used, users consistently get the same level of security and the same web filtering.
