Securing remote work: VPN and best practices for small businesses.
Public Wi-Fi, personal devices, unprotected remote access: remote work multiplies risks for small businesses. Here is how to reduce them simply.
Published on January 1, 2026
An employee connecting from a coffee shop, an administrative assistant using a family computer, a manager accessing accounting from home over an unsecured connection: remote work has become the norm, but the risks it creates are still largely underestimated in small businesses. The good news: a few well-chosen measures are enough to reduce the main exposure.
What are the main risks of remote work?
Working outside the office means leaving the perimeter protected by your local network. The most common risks are the following.
Unsecured public Wi-Fi. Open networks in cafes, hotels, or train stations do not encrypt the data passing through them. An attacker on the same network can intercept exchanges, capture credentials, or inject malicious content into pages being browsed.
Poorly protected personal devices. A family computer shared among several people often accumulates risks: software not updated, absent or expired antivirus, weak passwords, no disk encryption. Using it to access professional tools directly exposes the business.
Poorly configured remote access. A remote desktop (RDP) exposed directly to the Internet without additional protection is a prime target for attackers. Likewise, shared credentials or weak passwords on remote access points make intrusions easier.
Mixing personal and professional use. Downloading a personal file, visiting entertainment sites, or using unapproved tools on a work device increases the attack surface without the business being aware of it.
What is a VPN and what does it actually do?
A VPN (virtual private network) creates an encrypted tunnel between the team member’s device and the company network. In practice, it serves two main purposes.
Encrypting the connection. Even on public Wi-Fi, the data exchanged is unreadable to anyone intercepting the traffic. This is the most immediate use for employees on the move.
Accessing the company’s internal network. A corporate VPN makes it possible to reach resources that are not accessible from the Internet (internal servers, network printers, on-premise software) as if you were physically in the office.
A VPN is particularly useful if your team accesses resources hosted on your premises, or if you travel frequently. If your tools are entirely in the cloud (Microsoft 365, Google Workspace, SaaS accounting software), the priority is less about VPN and more about securing access itself: strong authentication, robust passwords, and rights management come first. We cover these points in our article on passwords and two-factor authentication.
For small businesses looking to test a VPN solution without heavy infrastructure, services like Tailscale or Cloudflare Zero Trust offer a good balance of accessibility and security, with plans suited to small teams.
What good practices should your team adopt?
A VPN only covers part of the risk. Here are the complementary practices that make a real difference day to day.
Keep devices up to date. Security updates fix known vulnerabilities that attackers actively exploit. A device that has not been updated in several weeks is an open door. Enable automatic updates on operating systems and software.
Encrypt hard drives. On Windows, BitLocker is built in and free. On macOS, FileVault serves the same purpose. If a laptop is stolen or lost, encryption makes the data inaccessible without the login password.
Use strong passwords and two-factor authentication. This is the foundation of any digital security. If it is not yet in place for your team, start there before even thinking about a VPN. You will find a practical guide in our dedicated article on passwords and two-factor authentication.
Separate personal and professional use. Ideally, a dedicated work device for professional use. If that is not possible, a separate browser profile, a distinct cloud storage space, and clear rules for downloads. Personal tools (consumer messaging apps, games, social media) have no place in a work environment.
Back up regularly. Remote work makes backups more complex if team members store files locally. Set a clear rule: every professional document must be saved to a company cloud space or a server backed up daily. The 3-2-1 rule (3 copies, 2 media types, 1 offsite copy) remains the reference.
Establish a remote work policy. Writing down the expected rules (network, approved devices, behavior when in doubt) clarifies responsibilities and reduces inadvertent risky behavior. A one-page document is enough for a small team.
How do you put this in place without spending weeks on it?
The temptation in small businesses is to defer these questions due to lack of time or in-house expertise. The result, in most cases, is a configuration that accumulates unreviewed until an incident occurs.
The approach we recommend is simple: start with a quick audit. What remote access points are in place? Who uses what, from which device? Which tools are in the cloud, which are on-premise? This diagnostic takes a few hours with an expert and makes it possible to prioritize actions according to the actual level of risk.

Where to start concretely?
A realistic action plan for a small team:
- Inventory existing remote access points (remote desktop, VPN, cloud access).
- Verify that all devices used remotely are up to date and encrypted.
- Enable two-factor authentication on all remote access points and critical tools.
- Define a clear policy on approved devices and personal/professional use.
- Set up automatic cloud backup for documents produced outside the office.
- Have an expert audit the configuration to identify blind spots.

Frequently asked questions
Is a VPN enough to secure remote work?
A VPN protects the network connection, but it does not replace the other measures: updates, strong passwords, two-factor authentication, and separation of personal and professional use. It is one layer among several, not a complete solution on its own.
Can our team members use their personal computers for work?
It is possible, but risky if the device is not protected (up-to-date antivirus, active encryption, strong passwords). Ideally, each team member has a dedicated work device. If using a personal device is unavoidable, set clear rules: a separate browser profile, mandatory VPN, and no professional documents stored locally without encryption.
How do we know if our remote work setup is secure enough?
A quick audit with an IT expert maps your remote access points, identifies weaknesses (unencrypted Wi-Fi, shared accounts, devices not updated), and prioritizes actions. At iokoo, our experts run this kind of diagnostic without jargon and guide you step by step.
