A free VPN on a personal phone is a judgement call. The same app on an office PC is a data-protection incident waiting for a date. Here is why offices must say no - and what to use instead.
The suggestion sounds thrifty: the office needs a VPN, free VPNs exist, problem solved. It is not solved - it is created. A VPN provider can see the destinations and traffic patterns of everything routed through it. On a work machine that means office email, accounting software, file servers and client data passing through servers run by a company your office has no contract with, no audit rights over, and often no name for. For personal browsing that is a privacy trade-off. For company data it is a compliance and security failure, and this page explains the correct alternatives.
A VPN does not remove trust; it moves it. Without a VPN, your internet provider sees your office's traffic destinations. With a free VPN, that visibility moves to the VPN company instead - a company that, in the free case, may log by business model, answer to no contract, and sit in any jurisdiction on earth. Paid business VPNs exist precisely to fix this: contracts, data-processing terms, audits and support. A free consumer app offers your office none of those, while asking for the deepest network access a program can have. No saving justifies that exchange with client data.
Even a harmless free VPN causes practical damage at work. It reroutes or blocks local network traffic, so shared printers, file shares and Tally or accounting servers on the LAN become unreachable or erratic - a classic mystery-outage source. Its one-device and data-cap limits (10 GB disappears fast across an office day) cut connections mid-work. Free servers get blacklisted by banks, government portals and email providers because abusers share the same exit IPs, so staff get locked out of exactly the sites the office needs. And when something breaks, there is no support line to call.
Name the real job and the right tool appears. Staff must reach office systems from home: use the VPN built into your office firewall or router, or a business remote-access tool your IT person controls - the office owns the server, not a stranger. Staff must work safely on hotel or cafe Wi-Fi: a reputable paid VPN under a company account, or the same office firewall VPN. The office wants one fixed public IP for banking allowlists: that comes from your internet provider as a static IP, never from a consumer VPN. Each real need has a controlled answer.
There is a small, honest exception: a personal free VPN from a verified provider - the Proton Free class - on a personal device, used for personal traffic, that happens to sit on the office desk. The moment that device opens office mail, office files or office systems, the exception ends. Offices should also say this in writing: one line in the IT rules - no personal VPN apps on office systems - prevents the well-meaning shortcut that creates the incident report later.

Small offices are also the least able to absorb a data incident. The firewall or router VPN you already own usually covers the real need at no extra cost.
That is their personal traffic on their personal device, which is a policy choice for the office. It still eats bandwidth and can complicate troubleshooting, so many offices simply disallow VPN apps on the work network. What must never happen is office accounts or office data going through that personal VPN.
Better, but still not the proper tool. A paid consumer VPN gives you a real company and support, yet the office still has no business contract or control. For remote access to office systems, the office firewall or router VPN - or a managed business service - is the correct shape.
