Firewall / VPN
Linux-based firewall and VPN infrastructure for organizations that need security, control, and flexibility
Security at the edge and secure access for the people who need it
A firewall and VPN platform does two related jobs for a business. It helps define, protect, and control the boundary of the network, and it provides secure access for users, offices, and systems that need to connect from elsewhere.
Our Firewall / VPN offering delivers a Linux-based security platform designed to handle both of those responsibilities in a practical, supportable way. That may mean securing internet-facing traffic, segmenting internal access, supporting remote staff, connecting branch sites, or creating a secure path into business systems from outside the office.
A strong fit for businesses that want control and flexibility
Our Firewall / VPN solution is especially well suited to organizations that want a security platform built on open-source foundations rather than a locked-down appliance model. A Linux-based firewall provides flexibility around policy design, routing, network segmentation, and operational visibility, while OpenVPN provides a mature and widely adopted way to deliver encrypted remote-access and site-to-site connectivity.
The result is a platform that can be shaped around the real network and access requirements of the business instead of forcing every environment into the same template.
Built for both perimeter protection and secure connectivity
On the firewall side, the goal is to enforce sensible traffic policy, reduce unnecessary exposure, and create a cleaner security boundary around business systems. On the VPN side, the goal is to give authorized users and locations a secure encrypted path into the resources they need, whether that is a remote-access use case or a site-to-site connection between networks.
Together, those two functions create a more complete network security foundation for organizations that need both tighter control and reliable connectivity.
A security platform is only valuable if it stays manageable
A firewall or VPN server is not just a one-time technical deployment. It needs policy maintenance, user administration, certificate and authentication management, monitoring, patching, and operational oversight that keeps it effective over time.
That is where Starnix adds value. We do not simply stand up a Linux firewall and OpenVPN server. We deliver a supported platform that is built to remain secure, understandable, and maintainable in production.
Our Firewall / VPN solution is built around a Linux-based platform that gives businesses strong control over network boundaries, traffic policy, routing behavior, segmentation, and access rules. This makes it a good fit for organizations that need more flexibility than a typical appliance can offer, whether the requirement is internet edge protection, inter-network filtering, NAT, port forwarding, or internal segmentation.
OpenVPN is a strong fit for secure remote access because it creates encrypted tunnels for users connecting over the internet back into private business resources. This allows staff, contractors, and administrators to work securely from off-site locations while keeping traffic protected in transit. OpenVPN’s business use cases center on secure remote access and secure connectivity into private networks from untrusted environments.
In addition to remote-access, OpenVPN supports site-to-site connectivity between business networks. That makes it useful for connecting branch offices, cloud environments, datacenters, and partner-connected segments through encrypted tunnels across public networks. OpenVPN specifically supports site-to-site networking and routing between distributed locations and private network environments.
OpenVPN supports a range of authentication methods, including certificates, username/password workflows, and integration with external identity systems. Access Server supports PAM, LDAP, RADIUS, and SAML, and it also supports MFA options including built-in TOTP and third-party integrations.
This gives our platform flexibility to fit into different business identity models, from local account management to centralized directory-backed access with stronger authentication requirements.
OpenVPN supports user-specific and group-specific access control policies, which allows the VPN layer to be aligned with the organization’s actual security model. On the network side, Linux-based firewall rules can be shaped around users, subnets, services, and trust boundaries so the platform does more than simply open a tunnel.
OpenVPN provides client support across major desktop and mobile platforms, which is important for organizations with mixed endpoint environments. That makes it easier to support secure access for Windows, macOS, Linux, iOS, Android, and other common user platforms without forcing your business into a single-device model.
OpenVPN operates as a full-featured SSL/TLS VPN and supports layer 2 or layer 3 secure network extension. In practice, that means it can be used in a range of network designs depending on how access, routing, and connectivity need to work across the environment.
Combined with a Linux-based firewall layer, this creates a platform for your business that supports both secure transport and practical enforcement of network policy at the edge.
Managed network security operations, not just a server deployment
A firewall and VPN platform only creates long-term value if it stays aligned with the business as users, systems, offices, and access requirements change. Once deployed, it needs ongoing attention to policy updates, user provisioning, certificate and authentication management, monitoring, and platform maintenance.
That is what Starnix provides. Our managed Firewall / VPN service is built to keep the environment secure and usable over time, not just get it running on day one.

- User, certificate, and authentication management
- Monitoring, alerting, and issue response
- Patch management and security maintenance
Support for both security policy and user experience
Firewall and VPN support is not only about blocking and allowing traffic. It is also about making sure legitimate users can connect reliably, access is scoped correctly, and the platform remains understandable to the people who depend on it.
That balance matters. A strong security posture should reduce risk without creating unnecessary operational friction for staff, administrators, or business workflows.
Built for Linux environments and adaptable to mixed networks
This product aligns naturally with Linux and open-source infrastructure, which is where Starnix brings the deepest operational experience. At the same time, the platform is well suited to mixed business environments where the firewall and VPN layer needs to support a range of client devices, remote users, offices, and private network segments.
The result is a security offering that feels technically credible to experienced administrators while remaining practical and dependable for organizations that simply need secure access and strong network control.
