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.

What you do online can be tracked by organizations you may not know or trust and become part of a permanent record. A VPN can’t solve this on its own, but can prevent your ISP from being able to share or sell your data. All servers managing the IVPN service are self-hosted and operated by IVPN, including email and live chat. We commit to annual security audits to improve our security practices and transparency. We never pay for reviews and do not have an affiliate program, so you won’t find us on the ‘top 10 best VPN’ lists. We don’t promise anonymity or ‘military grade encryption’. We publish extensive privacy guides and educate our customers on what a VPN can realistically achieve. We donate regularly to organizations fighting for the right to privacy like the EFF, Open Rights Group, and the Tor project. Our business model is exclusively based on paid subscriptions. We do not own any other VPN services or VPN review sites. Review the team operating IVPN and the company ownership.

Simple packet filters are becoming a thing of the past. Even the open-source domain is moving towards Next-Generation Firewalls. And OPNsense is a top player when it comes to intrusion detection, application control, web filtering, and anti-virus. No network is too insignificant to be spared by an attacker. Even home networks, washing machines, and smartwatches are threatened and require a secure environment. Firewalls are a component of the security concept. They protect against known and new threats to computers and networks. A firewall offers the highest level of protection if its functions are known, its operation is simple, and it is ideally positioned in the surrounding infrastructure. OPNsense accepts the challenge and meets these criteria in different ways. This book is the ideal companion for understanding, installing and setting up an OPNsense firewall.

NetBird is an open-source Zero Trust Networking platform built by engineers for engineers. It radically simplifies deploying secure private networks using the high-performance WireGuard® protocol.

Integrating seamlessly with your IdP for SSO and MFA, it forms direct, encrypted peer-to-peer tunnels between devices, servers, and clouds - no central bottlenecks or single points of failure. Lightweight clients ensure scalability and privacy, with traffic never passing through management services. NetBird supports integrations with CrowdStrike, Intune, SentinelOne, pfSense, and more. Ideal for Zero Trust remote access, multi-cloud connectivity, dynamic posture checks, detailed auditing, and MSP multi-tenant management - all through one intuitive platform.

The way we work has changed. People now work from anywhere, not just from an office. Applications are based in the cloud, not just on-premise. And the company network perimeter is now spread across the internet. Using a traditional, network-centric VPN for remote access is not only outdated and difficult to maintain, but exposes businesses to security breaches. VPN infrastructure is costly and time-consuming to procure, deploy, and maintain. Inability to secure access at the app level means hacks can expose whole networks. Twingate enables organizations to rapidly implement a modern Zero Trust network that is more secure and maintainable than VPNs. Delivered as a cloud-based service, Twingate empowers IT teams to easily configure a software-defined perimeter without changing infrastructure, and centrally manage user access to internal apps, whether they are on-prem or in the cloud.

AWS Client VPN is a fully managed remote access VPN solution used by your remote workforce to securely access resources within both AWS and your on-premises network. Fully elastic, it automatically scales up or down based on demand. When migrating applications to AWS, your users access them the same way before, during, and after the move. AWS Client VPN, including the software client, supports the OpenVPN protocol. Many organizations require multi-factor authentication and federated authentication from their VPN solution. AWS Client VPN supports these and other authentication methods. Traditional on-premises VPN services are limited by the capacity of the hardware that runs them. AWS Client VPN is a pay-as-you-go cloud VPN service that elastically scales up or down based on user demand. Unlike on-premises VPN services, AWS Client VPN allows users to connect to AWS networks using a single VPN connection.

AWS VPN enables secure connections between on-premises networks and AWS Virtual Private Clouds (VPCs) using IPsec VPN tunnels. Each connection includes two tunnels for high availability, terminating in different availability zones to ensure resilience. It supports both static and dynamic routing with BGP, and offers customizable tunnel options, including inside tunnel IP addresses, pre-shared keys, and BGP Autonomous System Numbers (ASNs). Accelerated Site-to-Site VPN leverages AWS Global Accelerator to route traffic through the nearest AWS edge location, improving performance by reducing latency and jitter. AWS Client VPN is a fully managed, elastic VPN service that allows users to securely access AWS and on-premises resources from any location using an OpenVPN-based client. It supports authentication through Active Directory, mutual certificate authentication, and SAML-based federated authentication.
