Best VPN Services for Azure Marketplace

OpenVPN Access Server is a self-hosted Zero Trust Network Access (ZTNA) solution you deploy into your own environment — on-prem or your AWS, Azure, or GCP account — so tunnel traffic and configuration never touch a third-party network. Access is enforced by application, not IP or subnet: each user reaches only the app they're entitled to, identified by domain name, with no visibility into anything else. That structurally blocks lateral movement — there's no connectivity path for a breach to exploit. With Access Server Link, deployment is a guided setup (hostname, cloud, region, password) with SSL certificates auto-provisioned and renewed, removing manual cert management as an attack surface. Entitlements tie to hostname, so they survive IP changes and autoscaling without rework. Your instance stays fully under your control, preserving the data ownership and audit posture required for HIPAA, SOC 2, and GDPR — full sovereignty over the control plane, with SaaS-level simplicity. The admin portal replaces SSH-based management: users, certificates, and access policies are configured through a browser, so shell access isn't required, shrinking your attack surface. The Zero Trust App Broker mediates every connection through a placeholder IP scoped to one authorized application — users never learn the real destination, so a compromised credential can't be used to probe or discover other systems. This enforces least privilege by design, not just by policy that can drift or be misconfigured. Client apps span Windows, macOS, iOS, Android, and Linux, so identity- and application-based controls apply consistently across devices. Deployment runs through preconfigured templates on AWS, Azure, and GCP, giving security teams repeatable, auditable rollouts.

Traditional packet filters are gradually becoming outdated, as even open-source solutions are shifting towards Next-Generation Firewalls. OPNsense stands out as a leading option for features like intrusion detection, application control, web filtering, and antivirus protection. No network, regardless of its size, is immune to potential attacks; even devices in home networks, such as washing machines and smartwatches, are at risk and need robust security measures. Firewalls play a crucial role in a comprehensive security strategy, shielding systems from both established and emerging threats. The effectiveness of a firewall is maximized when its capabilities are well understood, it operates intuitively, and is strategically placed within the network infrastructure. OPNsense rises to the occasion by fulfilling these essential requirements in various ways. This book serves as an invaluable guide for anyone looking to comprehend, install, and configure an OPNsense firewall effectively. Ultimately, understanding the intricacies of OPNsense can empower users to create a more secure digital environment.

CloudConnexa is OpenVPN's cloud-delivered Zero Trust Network Access (ZTNA) platform that also delivers core Security Service Edge (SSE) capabilities, letting organizations replace legacy VPN infrastructure with a fully managed, cloud-native service. Signing up provisions a private overlay network, conceptually a virtual distributed router and next-generation firewall, spanning 30+ global regions connected in a full-mesh topology for low-latency, redundant routing between points of presence. Private infrastructure joins this network through Connectors: Network Connectors attach entire private networks (offices, data centers, VPCs/VNets in AWS or Azure), while Host Connectors attach individual servers or IoT devices. Hosts run an OpenVPN client to expose specific services. Remote users, sites, and cloud resources connect over encrypted OpenVPN tunnels, with Data Channel Offload (DCO) support for higher throughput on Linux. Access is governed by identity-based, role- and group-based policies, with SAML, LDAP, and SCIM integration so admins scope users to only the resources they need. Application domain-based routing cloaks real IP addresses, enabling microsegmentation without exposing server infrastructure. Built-in Cyber Shield security bundles DNS content filtering across 43+ categories, intrusion detection/prevention (IDS/IPS), Device Identity Verification & Enforcement (DIVE) for posture checks, and two-factor authentication. Admins get audit logging, SIEM integration, and alerting for visibility and troubleshooting. It's all managed from a single cloud dashboard, giving organizations scalable, zero-trust connectivity without operating their own VPN servers.

Azure Private Link enables secure and private connections from a virtual network to various services, including Azure's platform as a service (PaaS), those owned by customers, or services offered by Microsoft partners. By doing so, it streamlines the network setup and enhances security by preventing data from being exposed to the public internet. This private connectivity ensures that all traffic to the Azure services stays within the Microsoft network, avoiding any public internet interactions. Users can utilize Private Link to integrate Azure-delivered services into their private virtual networks by linking them to a private endpoint. Additionally, businesses can offer their own services within their customers' virtual networks in a secure manner. With all service traffic directed through the private endpoint, there is no requirement for gateways, NAT devices, ExpressRoute, VPN connections, or public IPs, thereby maintaining the integrity of the connection. Ultimately, Private Link guarantees that all data transfers occur securely over the Microsoft global network. This feature not only enhances security but also simplifies the management of network resources.

WireGuard® is a modern VPN solution that is not only incredibly straightforward but also fast, built on advanced cryptography. Its goal is to outperform IPsec by being quicker, easier to use, more streamlined, and less troublesome. WireGuard is positioned to deliver superior performance compared to OpenVPN as well. Engineered as a versatile VPN, it can operate on both embedded devices and high-performance supercomputers, making it adaptable for a variety of scenarios. Originally developed for the Linux kernel, WireGuard has since become available across multiple platforms, including Windows, macOS, BSD, iOS, and Android, enhancing its accessibility. Although it is still evolving, it is already seen as one of the most secure, user-friendly, and straightforward VPN options available today. Configuration and deployment are designed to be as seamless as SSH, with VPN connections established through the simple exchange of public keys—similar to the method used for SSH keys—while WireGuard takes care of all other processes automatically. Additionally, it supports roaming across different IP addresses, resembling the functionality of Mosh, which enhances its usability for mobile users. Overall, WireGuard stands out in the VPN landscape due to its blend of cutting-edge technology and user-centric design.

Once an application is launched, developers and IT teams often find themselves preoccupied with securing it through measures such as configuring access control lists, changing IP addresses, and implementing cumbersome solutions like GRE tunnels. However, there exists a more straightforward and robust method for safeguarding your applications and web servers against direct threats: Cloudflare Tunnel. This solution ensures the protection of your server regardless of its hosting environment—be it a public cloud, private cloud, a Kubernetes cluster, or even a Mac mini positioned beneath your television. Cloudflare Tunnel serves as tunneling software that enables swift security and encryption of application traffic across diverse infrastructures, effectively concealing your web server's IP addresses, thwarting direct assaults, and allowing you to focus on delivering exceptional applications. By utilizing the Tunnel daemon, an encrypted connection is established between your origin web server and the closest Cloudflare data center, all without the need to open any public inbound ports. This way, your applications can thrive in a secure environment while you maintain peace of mind.
