What is MDR?
Managed Detection and Response combines continuous monitoring, investigation and human-led response to help organizations detect and contain threats.
MDR vs EDR: what is the difference?
EDR provides endpoint detection technology. MDR adds ongoing monitoring, investigation and response expertise around security telemetry.
What is a SOC?
A Security Operations Center is the people, processes and technology used to monitor security signals, investigate alerts and coordinate response.
What is SIEM?
Security Information and Event Management centralizes and analyzes security logs so suspicious activity can be detected and investigated.
MDR vs SIEM vs SOC
SIEM is primarily a technology layer, a SOC is an operating function, and MDR is a managed detection-and-response service. Many organizations use them together.
What is a vulnerability assessment?
A vulnerability assessment systematically identifies and prioritizes known weaknesses across systems, applications and infrastructure.
Vulnerability assessment vs penetration testing
A vulnerability assessment finds and prioritizes potential weaknesses; penetration testing goes further by safely testing whether selected weaknesses can be exploited.
What is penetration testing?
Penetration testing is an authorized security exercise that simulates realistic attack techniques to validate exploitable weaknesses and business risk.
What Microsoft 365 security should an SMB enable?
A practical baseline includes MFA, Conditional Access where licensing supports it, least privilege, email protection, endpoint controls, logging, recovery planning and regular configuration review.
What cybersecurity does a 25–50 employee business need?
Most organizations this size need identity protection, managed endpoints, email security, backups, vulnerability management, monitoring and response, security awareness and an incident-response plan.
How much does managed cybersecurity cost in Canada?
Cost varies by users, endpoints, coverage hours, technology stack, compliance requirements and response scope. Compare providers by included outcomes and coverage rather than a single per-user number.
What is a cybersecurity gap assessment?
A gap assessment compares current safeguards with business risk, regulatory expectations and a practical security baseline to identify prioritized improvements.
What is PIPEDA cybersecurity compliance?
PIPEDA requires organizations subject to it to use safeguards appropriate to the sensitivity of personal information and includes requirements around certain privacy breaches.
What is PHIPA security?
Ontario organizations handling personal health information need administrative, technical and physical safeguards appropriate to their PHIPA responsibilities and risks.
What is 24/7 security monitoring?
24/7 monitoring continuously reviews security signals so suspicious activity can be triaged and escalated outside normal business hours as well as during the day.
What is vulnerability management?
Vulnerability management is the ongoing cycle of discovering weaknesses, prioritizing them by risk, remediating them and verifying that fixes were effective.
Does a small business need MDR?
MDR can be valuable when a business lacks an internal security team but needs continuous detection, investigation and response capability.
Does a small business need a penetration test?
A penetration test is especially useful when required by a customer or framework, after significant system changes, or when an organization needs evidence that important controls withstand realistic attack paths.
What is incident response?
Incident response is the structured process used to prepare for, identify, contain, investigate, eradicate and recover from cybersecurity incidents.
What is ransomware resilience?
Ransomware resilience combines prevention, detection, containment, protected recovery and rehearsed incident response so one compromised account or device does not become a business-wide outage.

Start with your risk, not a product
Cybersecurity tools are most useful when they address a defined business risk. If you are unsure where to begin, assess identities, endpoints, email, cloud configuration, backups, vulnerabilities, monitoring and incident readiness first.
