Cybersecurity for small businesses in Trois-Rivières: 7 essential steps in 2026
In 2026, cyberattacks no longer target only large companies. Small businesses in Trois-Rivières and the Mauricie have become prime targets for attackers, precisely because they are often less well protected.
Here are 7 concrete steps to protect your company, with no internal IT team required.
Quick answer: To secure a small business in Trois-Rivières, apply 7 key measures: multi-factor authentication, tested backups, automatic updates, next-generation antivirus, phishing training, access management and an incident response plan.
1. Turn on MFA for every account
Why a password alone no longer holds
Multi-factor authentication (MFA) is the first line of defence against unauthorized access. Without it, one stolen password is enough to compromise your entire company.
- Turn on MFA for Microsoft 365, your email and your cloud tools
- Use an authenticator app rather than text messages
- Configure conditional access policies with Microsoft Entra
Solution: OKTO Solutions configures and manages MFA for all your applications in a matter of hours.
2. Put a verified offsite backup in place
The 3-2-1 rule for backups
Major data loss can stop a small business for days, sometimes weeks, and getting back on your feet almost always costs more than prevention. A backup that has never been tested is not a reliable backup.
- Back up your data outside your main network
- Test restoration at least once a quarter
- Apply the 3-2-1 rule: 3 copies, 2 different media, 1 offsite
Solution: our managed IT services in Trois-Rivières include backup monitoring with automatic alerts.
3. Train your employees on phishing
What good training has to include
The human element is present in 62 percent of breaches, and phishing is the way in for 16 percent of them, across all organizations. For small businesses alone, the same report gives 45 percent and 9 percent (Verizon, Data Breach Investigations Report 2026). Your employees are your first line of defence, or your biggest weakness.
- Run awareness sessions twice a year
- Simulate phishing attacks to test alertness
- Set a clear procedure for reporting suspicious email
Solution: we offer ready-to-use awareness programs built for small businesses in the Mauricie.
4. Control access by role
Every employee should only reach the data they need to do their job. Too many admin rights create enormous risk the moment an account is compromised.
- Apply the principle of least privilege
- Revoke access immediately when someone leaves
- Audit access at least twice a year
Solution: automate onboarding and offboarding with Microsoft 365 and Entra ID.
5. Keep your systems up to date
Security updates fix known holes that attackers actively exploit. An unpatched system is an open door.
- Automate Windows and critical software updates
- Schedule restarts outside working hours
- Include network equipment in your update cycle
Solution: our full IT management includes automated patch management for every device.
6. Monitor your network in real time
Without active monitoring, an intrusion can go unnoticed for months. The average time to identify a breach is 181 days, and it takes another 60 to contain it (IBM, Cost of a Data Breach Report 2025).
- Install an intrusion detection system
- Configure automatic alerts on suspicious activity
- Review event logs regularly
Solution: our round-the-clock monitoring detects and blocks threats before they cause damage.
7. Have an incident response plan
The first 5 actions during an attack
It is not a question of whether you will be attacked, but when. Companies with a written, already tested response plan get back on their feet faster, because nobody wastes time working out who does what.
- Define who does what during an attack
- Prepare a list of emergency contacts (IT, insurer, legal)
- Test your plan once a year with a simulated exercise
Solution: OKTO Solutions helps you build a business continuity plan suited to small companies in Trois-Rivières.
Why act now? In 2023, 16 percent of Canadian businesses suffered a cybersecurity incident, including 14 percent of small businesses with 10 to 49 employees (Statistics Canada, Canadian Survey of Cyber Security and Cybercrime, 2023). The survey counted only incidents that had an impact, so the real figure is higher. The question is no longer whether you will be a target, but when.
