Remote teams often use the words proxy and VPN as if they meant the same thing. Both route traffic through another server, and both can change the IP address that a website sees. Beyond that, they solve different problems, and choosing the wrong one leads to gaps in security or unnecessary complexity.
This guide explains what each tool does, compares them side by side, shows when running your own VPN server is worth the effort and outlines the access policy that should come with it.
What a Proxy Does
A forward proxy sits between a user’s application and the internet. The application, often a browser or a script, sends its requests to the proxy, which forwards them and returns the responses. Only the traffic of applications configured to use the proxy goes through it.
HTTP proxies handle web traffic, while SOCKS proxies can relay other protocols as well. Authentication is usually handled with usernames and passwords or with lists of allowed IP addresses. Proxies are useful for tasks such as testing how a website or an ad looks from another country, managing outbound access from a group of servers, caching frequently requested content or applying web filtering policies. Proxies are also common in automated workflows: monitoring tools, testing frameworks and scripts that collect public data within a site’s terms often send requests through them, and those workflows need the same care with credentials and logging as user traffic.
A reverse proxy is a different tool: it sits in front of your own servers and handles incoming requests, often for load balancing or TLS termination. It does not protect a remote employee’s connection.
Keep in mind that a proxy does not automatically encrypt anything. If the application talks to the proxy over plain HTTP, the traffic between them can be read by anyone on the same network. HTTPS websites remain encrypted end to end, but the proxy still sees which sites are being contacted.
What a VPN Does
A VPN creates an encrypted tunnel at the network level. Once connected, the device can route all or selected traffic through the tunnel, regardless of which application generates it. For remote teams, the most common use is secure access to internal systems such as databases, admin panels and file shares that should never be exposed to the public internet.
A VPN can run as a full tunnel, which sends all traffic through the company network, or as a split tunnel, which sends only traffic for internal systems through the VPN. Split tunneling reduces load and latency for everyday browsing, while a full tunnel gives more control over traffic leaving managed devices.
VPNs also connect sites rather than people. A site-to-site tunnel links an office network to servers in a data center, so that the two behave like one private network without exposing internal services to the internet.
Modern VPN software has become much simpler to run. WireGuard, for example, uses a small codebase and modern cryptography, and it is now a common choice for self-hosted VPNs. OpenVPN remains widely used as well, especially where its long track record, flexible authentication options or ability to run over TCP port 443 matter more than raw speed.

In practice, many companies use both: a VPN for access to internal resources and a proxy for specific outbound tasks. The deciding question is simple: does the person need to reach something private, or only to appear from a particular place?
When Self-Hosting Makes Sense
Commercial VPN services are built for consumer privacy, not for reaching your company’s internal systems. For business use, a self-hosted VPN gives you control over who connects, what is logged and which IP address your traffic leaves from. A fixed outbound address is particularly useful when partners allow access to their systems only from known IPs.
Self-hosting also means you are responsible for updates, monitoring and user management. If you go this route, Unihost has published a step-by-step guide to running a VPN on dedicated server hardware, which compares WireGuard with OpenVPN and walks through requirements and setup. Whichever server you use, place it in a location close to most of your team to keep latency low.
What the Server Needs
A VPN server for a small or mid-sized team does not need much computing power, because modern protocols are efficient. The network matters more: a fast, stable connection, enough monthly traffic for full-tunnel users and a static public IP address. Choose a recent long-term-support Linux distribution, keep the firewall closed except for the VPN port and the management access you need, and monitor the service like any other production system.
Plan for at least basic redundancy if the VPN is the only way to reach internal systems. A second server, or a documented way to reach those systems without the VPN in an emergency, prevents a single failure from locking the whole team out.
Policy Matters More Than Protocol
The tool is only half of the answer. Decide who receives access, review the list when people join or leave, and remove keys immediately when a device is lost. Log connections in a way that supports investigations without collecting more personal data than necessary.
For contractors, issue time-limited access that expires automatically at the end of the engagement, and document which systems are reachable through the VPN so that access can be reviewed system by system. Where possible, combine the VPN with single sign-on or multi-factor authentication for the internal applications themselves, so that a stolen device key alone is not enough to reach sensitive data. Write these rules down before the first user connects. Review the configuration regularly as well: remove unused peers, rotate keys on a schedule and check that firewall rules still allow only the internal systems each group needs.
Proxies and VPNs are complementary tools. Use a VPN when people need secure access to internal systems, use a proxy for controlled outbound traffic and treat access policy as seriously as the technology itself.
