Teleworking has become a permanent fixture in the work habits of SMEs in the Mauricie and Trois-Rivières regions. What began as an emergency measure has become normal practice, even expected by employees. However, many companies have adopted remote work without implementing the necessary security measures, and hackers are well aware of this.

Securing remote work in an SME is achievable even without a large IT team. With the right tools and a structured approach, a team of 5 to 50 people can maintain a robust level of protection. This guide covers the essential elements of secure remote work for your SME: access control, remote device management, best practices for your employees, and incident response procedures.

1. Understand why remote work creates new risks for your SME

At the office, all your devices connect through a corporate network protected by a firewall, monitored, and regularly updated. When working remotely, each employee essentially becomes their own network administrator, often without the necessary skills or tools. Home Wi-Fi networks, shared with family and sometimes poorly configured, are not designed for secure professional use.

The Canadian Centre for Cyber ​​Security reminds us that small and medium-sized businesses are among the most frequent targets of cybercriminals, largely because they have fewer resources to detect and respond to intrusions. Remote work amplifies this risk by multiplying the entry points to your data and systems.

• Unsecured home networks: Wi-Fi without WPA3 protocol or with a weak password is vulnerable to interception.
• Shared or personal devices: a computer used by an employee and their children does not offer the same guarantees as a workstation managed by your IT team.
• Neglected updates: without centralized monitoring, security patches can remain pending for weeks, leaving exploitable vulnerabilities.
• Unencrypted connections: accessing company systems from a cafe or hotel exposes data in transit.
• Targeted phishing: Employees isolated at home are more likely to fall victim to fraudulent emails, especially outside of normal business hours.

2. VPN or conditional access: which protection to choose for remote connections

The question often comes up during our meetings with SMEs in Trois-Rivières and Mauricie: should we deploy a VPN or rely on Microsoft conditional access? Both options are valid, but they do not address the same realities.

Enterprise VPN: ideal for locally hosted resources

A VPN creates an encrypted tunnel between an employee's device and your office network. It's the ideal solution when your critical data and applications are hosted locally: internal file servers, accounting software on a corporate network, or in-house ERP systems. A VPN gives the impression of being physically present in the office from anywhere. Its main drawback is that it can slow down connections if all traffic is rerouted, and managing it requires some technical expertise.

Microsoft Entra ID Conditional Access: for Microsoft 365 environments

For small and medium-sized businesses (SMBs) using Microsoft 365, conditional access is often the best approach. Rather than creating a permanent tunnel, it applies specific rules: access to SharePoint files is granted only if the device complies with security policies, the user has enabled two-factor authentication, and the connection originates from a recognized country. It's more flexible than a VPN and integrates seamlessly with the Microsoft ecosystem without complex network configuration.

In all cases, multi-factor authentication (MFA) is the essential, non-negotiable measure for any secure remote work environment in SMEs. Microsoft has documented that MFA blocks over 99% of account compromise attempts. It's an accessible, quick-to-deploy protection that truly makes a difference for organizations with limited IT resources.

3. Manage your employees' devices remotely with Microsoft Intune

When your employee leaves for work from home with their laptop, how do you know if it's up to date? If it's encrypted? If they haven't downloaded suspicious software? Without a device management tool, you're operating in the dark. This is precisely the problem that Microsoft Intune, included in Microsoft 365 Business Premium plans, solves.

• Centralized security policies: enforce BitLocker encryption on all laptops, impose a PIN lock code, and block access to non-compliant devices.
• Automatic updates: ensuring that each workstation receives Windows patches as soon as they are released, without depending on the goodwill of the employee.
• Remote erasure: if a device is lost or stolen, erase company data in minutes from the administration console, without touching personal data.
• Real-time inventory: know at all times which devices are accessing your resources, from which city, and whether their security settings comply with your policies.
• Separation of profiles: on employees' personal phones, Intune only manages the professional portion, without accessing private photos or messages.

4. Good practices to pass on to your employees working remotely

Technological tools alone are not enough. An analysis published by IBM highlighted that human error is involved in the vast majority of cybersecurity incidents. Awareness training remains essential, even with the best protection software. One well-informed employee is worth more than three poorly configured firewalls.

Practical rules to communicate to your team

• Always enable the VPN or verify that conditional access is working before working from a network outside the office.
• Lock your computer screen as soon as you leave it, even temporarily, even at home.
• Use only company-approved tools to share work files (OneDrive, SharePoint), not personal services like WeTransfer or private chat groups.
• Report any unusual behavior on your device immediately: sudden slowness, unexpected windows, emails sent for no reason.
• Never plug in a USB key of unknown origin, even if found in a parking lot or received in the mail.

Our recommendation for SMEs in the Mauricie region: a 30- to 45-minute awareness session per year, with concrete examples of recent scams observed in the region. The goal is not to create fear, but to maintain a natural level of vigilance within each team on a daily basis.

5. Protocol to follow if a device is lost or stolen

It's a scenario we never fully anticipate: a cell phone left in a café in Trois-Rivières, a phone falling out of a pocket during a business trip. Without a pre-established procedure, these incidents can quickly escalate. With a clear protocol and the right tools in place, the window of risk is reduced to a few hours rather than several days.

1. Immediate reporting: the employee contacts the IT team within 30 minutes of the loss, regardless of the time or day.
2. Revoking access: Disabling the user's Microsoft 365 account will cut off access to email, SharePoint, and Teams.
3. Remote wipe: Initiate the procedure via Microsoft Intune to remove corporate data from the missing device.
4. Analysis of access logs: check recent connections in Microsoft Entra ID to detect any abnormal access during the loss window.
5. Incident documentation: prepare a report for compliance with Quebec Law 25 and for your cybersecurity insurance file.

This protocol should fit on a single page, be accessible to everyone via a Teams channel or intranet, and be reviewed annually. The speed of response in the initial hours is directly linked to the extent of the potential damage to your SME.

Frequently Asked Questions

Is a free VPN sufficient for my team working remotely?

No, and some free VPNs are themselves a risk. Many monetize their users' browsing data and offer no guarantee of confidentiality for business use. For an SMB, an enterprise VPN solution or conditional access via Microsoft 365 Business Premium offers a level of control, reliability, and logging that is unmatched by free consumer options.

Does Microsoft Intune work with Macs and Android phones?

Yes, Intune is a multi-platform solution that manages Windows PCs, Macs, iPhones, and Android devices from a single, centralized console. This is a significant advantage for Quebec SMEs whose teams often use a mix of devices from different brands.

Does Quebec's Bill 25 apply to incidents occurring while teleworking?

Yes, absolutely. Law 25 covers all personal data your company processes, regardless of where the incident occurs. A breach caused by an unsecured remote work device triggers the same reporting and management obligations as an incident occurring in your offices, and the reporting deadlines to the Access to Information Commission apply in the same way.
