		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. 105 Ratings Visit Website
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 Viscosity has been designed from the ground up for both macOS and Windows, using native frameworks for perfect integration. Viscosity has been protecting users for over a decade, everyone from home users to large enterprise, with regular updates the entire time. Viscosity monitors your OpenVPN connections to ensure you know all the important traffic, network and connection details in style. Easily bundle Viscosity with settings and connections so your users are ready to get started. Create simple deployable connection profiles. Powerful authentication options, connection folders, IPv6, traffic obfuscation, advanced networking, simultaneous connections, and more! Every component of Viscosity has been designed to maximise the speed and reliability of your OpenVPN connections. Control Viscosity using AppleScript or VBScript, and call custom scripts and actions when a VPN connection changes state.

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.
