How to Protect Your Ottawa Business from Ransomware in 2025

Ransomware attacks on Canadian SMBs increased 67% in 2024. Ottawa businesses — especially those with government contracts — are prime targets. Here's exactly what you need to do.

How to Protect Your Ottawa Business from Ransomware in 2025

Ransomware doesn't just hit large enterprises. In 2024, over 60% of ransomware victims were businesses with fewer than 250 employees — and Canadian SMBs paid an average of $1.13M CAD per incident including downtime, recovery, and reputational damage.

Ottawa businesses are particularly attractive targets because of the high concentration of federal contractors, law firms, and healthcare providers holding sensitive data.

What Ransomware Actually Does Modern ransomware doesn't just encrypt your files. It first *exfiltrates* your data, then encrypts it. Attackers then threaten to publish the data publicly unless you pay — even if you have backups.

The 7-Layer Defense SecRealm Recommends

  • Multi-Factor Authentication (MFA) on everything — Over 80% of breaches involve compromised credentials. MFA stops most of them cold.

2. Endpoint Detection & Response (EDR) — Traditional antivirus detects known threats. EDR detects *behaviour* — catching zero-days before they execute.

3. Immutable Offsite Backups — Backups that ransomware can't reach or encrypt. We use air-gapped and cloud-based immutable storage.

4. Email Filtering & Anti-Phishing — 91% of attacks start with a phishing email. Advanced email filtering with sandboxing stops malicious attachments before they land.

5. Network Segmentation — If ransomware infects one machine, segmentation stops it spreading to your entire network.

6. Patch Management — Unpatched software is the #1 ransomware entry point. We automate patching across all endpoints.

7. Security Awareness Training — Your staff are both your biggest vulnerability and your best defence. Regular simulated phishing training reduces click rates by over 70%.

What to Do If You're Infected 1. Disconnect from the network immediately — do not shut down 2. Call your IT provider — do not pay the ransom 3. Engage a cybersecurity incident response firm 4. Notify the Office of the Privacy Commissioner if personal data was involved
