OpenVPN Access Server is business VPN software built to give organizations secure remote access to their network and resources without the cost and complexity of legacy hardware. Available as a self-hosted VPN server, it can be deployed in the cloud or on-premises, making it a flexible VPN for business teams that are remote, hybrid, or in-office. Because it runs on infrastructure you control, it's easily one of the best business VPN and best VPN for business picks for organizations that want a genuine VPN service for business without long-term vendor lock-in, whether you're a growing team looking for a VPN for small business or a larger organization that needs an enterprise VPN with high availability and clustering. Positioned as a remote access VPN, or simply a VPN for remote access, Access Server layers in essential zero trust network access (ZTNA) capabilities: granular permissions, least-privilege enforcement, and verification that connections come from trusted devices and locations. This makes it a strong secure remote access VPN choice for protecting sensitive data and isolating SaaS applications from the open internet. It also supports site-to-site VPN connections, extending your business network securely to remote offices. For deployment, Access Server offers real flexibility as VPN server hosting: pre-configured images are available for AWS, Google Cloud, Microsoft Azure, DigitalOcean, Oracle Cloud, and IBM Cloud, giving you a cloud VPN service option, or you can run it as an on-premises VPN on your own hardware. Whether you prefer a fully managed VPN experience or hands-on control, Access Server can function as a VPN-as-a-service through your infrastructure provider, and it pairs an intuitive Admin Web UI, REST/XML-RPC API, and command-line tools with strong security: built-in X.509 PKI, SAML/LDAP/RADIUS authentication, multi-factor authentication, and AES-256-GCM encryption. The result is one of the more complete VPN solutions for businesses that need scalable, cost-effective, and genuinely secure connectivity as they grow.
