Best 24/7 Cybersecurity Monitoring Services for Canadian Businesses (2025 Edition)
In 2025, Canadian businesses of all sizes are facing a rapidly evolving cyber threat landscape. Ransomware attacks and data breaches are no longer “if” but “when”-with devastating effects. For instance, manufacturing firms worldwide lose an average of US$1.9 million per day to ransomware-related downtime, sometimes lasting weeks. In Canada specifically, over 70% of MSPs report that ransomware victims experienced business-threatening downtime, illustrating how crippling such attacks can be.
To stay resilient, companies must invest in 24/7 cybersecurity monitoring services that detect threats early and respond instantly-minimizing downtime, losses, and reputational damage.
Below, we’ve compiled eight of the top providers offering round-the-clock monitoring, incident detection, and response for Canadian businesses. These range from global giants to Canadian-owned specialists, each bringing unique strengths to the table-starting with OneArrow Consulting, known for its rapid ransomware recovery capabilities.
Here are the best cybersecurity monitoring companies with their services
1. OneArrow Consulting
OneArrow Consulting offers 24/7 ransomware protection and recovery, with a particular focus on minimizing business disruption for SMBs and enterprises alike. Their approach includes continuous monitoring, immediate incident response, and tailored recovery plans that prioritize speed-so businesses are back online faster, not just safer.
By combining proactive defense with rapid recovery, OneArrow bridges a critical gap: many providers detect threats but don’t deliver recovery as swiftly. OneArrow excels at both-making it ideally suited for businesses that demand both vigilance and action.
2. eSentire
Founded in 2001 and based in Waterloo, eSentire is a recognized leader in Managed Detection and Response (MDR). They protect over 2,000 clients across 80 countries using AI-powered threat detection and a 24/7 Security Operations Center (SOC).
Their offering includes AI-augmented tools like Atlas (generative AI) and open XDR platforms, complemented by human-led threat hunting, incident response, and continuous threat exposure management. This hybrid approach of automated and expert response makes them a robust choice-particularly for businesses seeking scalable, intelligent protection.
3. Arctic Wolf
Arctic Wolf delivers Managed Detection and Response that covers networks, endpoints, and cloud environments 24/7. Their strength lies in a concierge-style model: a dedicated security operations team actively monitors, investigates, and responds to threats.
Though US-based, Arctic Wolf has made strategic investments in Canada-running R&D and SOC hubs in Waterloo and Toronto following its high-profile expansion. Their adoption of advanced analytics and their personalized engagement model (regular posture reviews, guided remediation) make them a strong fit for mid-market and growing enterprises.
That said, in some public forums, users report challenges-such as slow escalations or alert fatigue. It’s a reminder to pair automated detection with transparent communication expectations.
4. Herjavec Group
Originally founded by Robert Herjavec in 2003, The Herjavec Group (now branded as Cyderes) is one of Canada’s largest IT security providers, boasting over US$200 million in annual revenue. They operate a global footprint offering enterprise-scale 24/7 security monitoring, ransomware containment, and incident response services.
Their strong Canadian roots and global resources make them a go-to for larger organizations needing deep expertise and broad SOC coverage.
5. Telus Cybersecurity
Telus, a leading Canadian telecom company, also offers SOC-as-a-Service, including Managed Detection and Response (MDR). Their offerings are strong in terms of network integration and coverage.
However, some feedback suggests variability in managed service delivery, especially when Telus ventures outside its core telecom services. This makes Telus potentially ideal for organizations already aligned with their network infrastructure-but worth vetting carefully on MDR expectations.
6. Bell Canada Security
Bell Canada brings cybersecurity to a national scale, backed by its network infrastructure and expertise. Their 24/7 SOC services include Managed MDR, XDR, IDS/IPS, endpoint protection, and incident escalation, anchored by SentinelOne’s Singularity platform.
Bell’s nationwide coverage and 700+ certified security professionals make them a trusted provider for regulated industries such as government, finance, and enterprise organizations. Their consistent recognition as a leader in security services by IDC further underscores their credibility.
7. IBM Security Canada
IBM Security Canada, part of the global IBM Security division, delivers enterprise-level monitoring with AI-driven detection, threat intelligence, and cyber simulations. Their Security X-Force is known for advanced capabilities tailored to highly regulated sectors-such as healthcare, finance, and critical infrastructure. Though typically enterprise-oriented, their depth of tools and intelligence makes them formidable defenders against sophisticated ransomware threats.
8. CyberSapiens
CyberSapiens is an emerging SOC service provider geared toward SMBs in Canada. They offer 24/7 monitoring, proactive threat detection using SIEM systems, and compliance-focused solutions for frameworks like HIPAA, GDPR, and PCI DSS. Their emphasis on tailored service and cost-effective deployment makes them an entry-friendly option for businesses seeking flexible cybersecurity without high enterprise costs.
