		Related Products Cloudbrink If you’ve ever dealt with slow VPNs, or clunky ZTNA agents that degrade app performance, you’re not alone. Many IT teams are stuck balancing security with usability—and often end up sacrificing both. Here is a different approach. The high-performance ZTNA service that is part of a personal SASE solution from Cloudbrink can upgrade or replace traditional VPNs while fixing the performance and complexity that come from other vendors in the ZTNA and SASE space. Built as a software-only service, Cloudbrink delivers sub-20ms latency and 1Gbps+ speeds per user using dynamically deployed FAST edges and a proprietary protocol that recovers packet loss before it impacts the app. Security isn’t bolted on—it’s built in. With mutual TLS 1.3, short-lived certs, and no exposed IPs, Cloudbrink provides real zero trust without making users suffer through poor connections or overloaded POPs. If you’ve been burned by “next-gen” solutions that still feel like 2008, it might be time for something new. 28 Ratings Visit Website Proton VPN Protect your business against damaging data breaches and easily comply with security frameworks like ISO 27001, GDPR, and HIPAA.

The model is least privilege: a user or an application receives the specific access its task requires and nothing more. This closes off a common attack route, since permanent local admin rights are what an attacker inherits when malware executes or a credential is stolen. Removing admin rights does not push users back into support queues. When someone needs a longer stretch of elevated work, they run an Admin Session that expires on its own. When they need only one program elevated, Run As Admin handles that alone and leaves the rest of the system unprivileged. Requests can be approved through the portal, the mobile app, or the API. Files receive an OPSWAT MetaDefender reputation check before elevation, and software that has already been vetted can clear automatically through pre-approval or the AI and Machine Learning approval engine. A single agent supports Windows, macOS, and Linux and behaves the same whether the endpoint is online or offline. Auditing and inventory are included as standard. 101 Ratings Visit Website Keeper Security Keeper Security is transforming the way people and organizations around the world secure their passwords and passkeys, secrets and confidential information.

About OpenVPN Access Server is a self-hosted Zero Trust Network Access (ZTNA) and business VPN solution that gives organizations full control over their own secure network. It's software organizations deploy directly into their own environment — on-premises hardware or their own cloud account on AWS, Azure, Google Cloud, or others — with tunnel traffic flowing directly between users and the server. With Access Server Link, teams can go from zero to a fully configured deployment in minutes: point-and-click setup across AWS, Azure, and GCP, automatic SSL certificate provisioning and renewal, and a web-based admin portal for managing users, certificates, and access — no SSH or manual DNS work required. Access is granted per application and per identity using domain names rather than broad network-level access, so users only reach what they're explicitly permitted to, and lateral movement is structurally blocked.	About Zscaler, creator of the Zero Trust Exchange platform, uses the largest security cloud on the planet to make doing business and navigating change a simpler, faster, and more productive experience. The Zscaler Zero Trust Exchange enables fast, secure connections and allows your employees to work from anywhere using the internet as the corporate network.

Pros & Cons from Real Users Pros Open Source. lots of customization options. Create your own VPN profile using free networks available on sites such as vpnbook. Also available as a service - pay as you go model. Cross Platform. The software made the process of setting up a Virtual Private Network so much easier. It has a lot of configuration options available including the use of DNS servers, user permissions and more. OpenVPN has support that will help with any issues needed. Cons Initial setup is difficult - creating profiles, installing certificate (at least on windows). It still requires a fair bit of work to actually set up the Virtual Private Network.	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.
