Pros & Cons from Real Users Pros We acquired the solution for our deployment in our branches with a goal of load balancing and QoS features, I have to say that we were impressed by the quality of the solution and the professionalism of the support team. I highly recommend CacheGuard. Hello! I just wanted to drop a quick note to let you know that I've been really impressed with CacheGuard. The service has been incredibly user-friendly and has exceeded my expectations in terms of simplicity and effectiveness. Cons We have the solution in production and so far so good. I also wanted to express my sincere appreciation to the CacheGuard support team. They've been fantastic in providing prompt and helpful assistance whenever I've needed it. Thank You.	Pros & Cons from Real Users Pros 1) Zscaler provides a Secure Web Gateway to protect users from malicious internet traffic, phishing, malware, and other online threats. It performs deep inspection of web traffic (including SSL/TLS encryption) and enforces security policies for safe browsing. This functionality is key to mitigating web-based threats for remote and mobile users 2) Zscaler offers a cloud-based next-gen firewall with advanced capabilities such as application-based control, intrusion prevention, URL filtering, and DNS filtering. The firewall is capable of securing both north-south (data center-to-cloud) and east-west (internal network) traffic. It’s highly scalable, eliminating the need for on-premises firewall appliances 3) Zscaler includes DLP capabilities that help organizations prevent sensitive data from leaving the network. This feature works across web, cloud, and email traffic to enforce policies on data sharing, ensuring that no unauthorized data is uploaded or shared 4) Zscaler employs advanced threat detection techniques, including threat intelligence, anomaly detection, and machine learning, to identify and mitigate sophisticated cyberattacks. By monitoring traffic in real time, it can detect and block malware, ransomware, and other malicious activities 5) Zscaler enables secure access to private applications without the need for a VPN. By using Zscaler Private Access (ZPA), users can securely connect to internal applications (both legacy and cloud-based) from any device or location, reducing the complexity of managing VPNs Zscaler Proxy operates entirely in the cloud, eliminating the need for on-premises hardware or complex infrastructure. This allows for easy scalability and a simplified architecture, which is particularly advantageous for organizations with remote or distributed teams. As a next-gen proxy, Zscaler Proxy offers real-time security inspection of all web traffic, ensuring protection from malware, ransomware, phishing, and other cyber threats. It uses advanced threat intelligence and machine learning to detect and block malicious activity before it can reach users or critical systems. Zscaler’s proxy ensures that users experience minimal latency while their web traffic is being secured. Since the service is cloud-based, users are automatically routed through the nearest data center, ensuring fast and uninterrupted access to web resources. The platform provides robust policy control, allowing organizations to enforce detailed security rules for web traffic, such as access restrictions, content filtering, data loss prevention (DLP), and URL categorization. Administrators can configure policies based on user identity, location, device type, and more, ensuring tailored protection. Since Zscaler Proxy routes traffic through its globally distributed cloud platform, it can improve network performance and reduce latency. By caching frequently accessed content at local points of presence, Zscaler ensures fast delivery of content while optimizing bandwidth usage. Very fast set up and it connects right away. Great VPN to use and is user friendly. Also has great connection! Cons 1) Since Zscaler is a cloud-based security solution, it requires an active internet connection to function. If users are offline or disconnected from the Zscaler cloud infrastructure, they may lose access to security features, leaving them vulnerable. This can be a disadvantage for users in remote locations or those with intermittent network access 2) Zscaler's cloud-based architecture means that data is processed and stored in its global data centers. This could raise concerns for organizations with strict data residency or compliance requirements, particularly in highly regulated industries (e.g., healthcare, finance, government). Some organizations may prefer on-premises or private cloud solutions for better control over data location and storage As a cloud-based solution, Zscaler Proxy is heavily reliant on internet connectivity. While the global infrastructure is designed to mitigate connectivity issues, any internet outages or disruptions could potentially impact traffic inspection and user access to the web. While basic configurations are straightforward, some of the more advanced settings (such as SSL inspection, custom policies, and integration with third-party systems) can be challenging for new users. The learning curve may require dedicated resources to fully utilize the platform’s capabilities. Sometimes I notice my pages take a little longer to load but other than that I have no cons I can name.
