EDR vs. MDR: What BC Small Businesses Need to Know About Endpoint Security
If your BC business is still relying on basic antivirus software, you’re behind. Not dangerously behind, necessarily — but behind in a way that leaves meaningful gaps that attackers actively exploit.
EDR (Endpoint Detection and Response) and MDR (Managed Detection and Response) are the modern replacements for traditional antivirus. Understanding what they do and how they differ will help you make better decisions about your BC business’s security posture.
Why Basic Antivirus Isn’t Enough
Traditional antivirus works by comparing files against a database of known malicious signatures. It’s effective against known, common malware — but it has fundamental limitations:
- Zero-day threats: New malware that hasn’t been catalogued yet won’t be detected
- Fileless malware: Attacks that run in memory without writing files to disk bypass signature scanning entirely
- Living-off-the-land attacks: Attackers using legitimate tools (PowerShell, WMI, remote desktop) to move through your network look like normal activity to basic AV
- Ransomware variants: Modern ransomware is often slightly modified to evade signature detection
Against sophisticated, financially-motivated ransomware operators targeting BC businesses, basic antivirus is not an adequate defence.
What Is EDR (Endpoint Detection and Response)?
EDR goes significantly beyond signature-based detection. Instead of just comparing files to a list of known threats, EDR software:
- Continuously monitors endpoint behaviour — every process, network connection, file operation, and registry change on every device
- Detects anomalies and suspicious patterns — identifying attacker behaviour even when no known malicious file is involved
- Provides investigation capabilities — security teams (or your MSP) can see exactly what happened on an endpoint and trace an attack’s path through your network
- Enables response actions — isolate a compromised device, kill malicious processes, roll back changes, all from a central console
Examples of EDR tools used in BC businesses: CrowdStrike Falcon, SentinelOne, Microsoft Defender for Endpoint (included with M365 Business Premium), Sophos Intercept X.
For most BC small businesses, EDR is the appropriate baseline security tool. The step up from basic antivirus is meaningful — and so is the gap in protection it closes.
What Is MDR (Managed Detection and Response)?
MDR is EDR with a human element added: a dedicated security operations team (SOC) that monitors your alerts 24/7, investigates suspicious activity, and responds to threats on your behalf.
With EDR alone, you get excellent detection capability — but someone still needs to watch the dashboard. For most BC small businesses, that’s your MSP or IT administrator, and it’s typically not someone whose full-time job is watching security alerts.
MDR adds:
- 24/7 SOC monitoring — trained analysts watching alerts around the clock
- Threat hunting — proactively searching for signs of compromise, not just waiting for alerts
- Incident response — when a real threat is confirmed, the MDR team acts immediately, not just notifying you
- Forensic investigation — understanding how a breach occurred and ensuring complete remediation
MDR is typically offered as a bundled service or add-on to an existing managed IT relationship. It’s the right choice for BC businesses with:
- Regulated data (healthcare, legal, financial)
- High cyber insurance requirements
- No in-house security expertise
- Operations where a successful breach would be catastrophic
EDR vs. MDR: Which Does Your BC Business Need?
| Factor | EDR | MDR |
|---|---|---|
| Detection capability | Excellent | Excellent |
| 24/7 monitoring | No (your team monitors) | Yes (SOC team) |
| Incident response speed | Depends on your team | Fast — SOC acts immediately |
| Pricing model | Per endpoint, add-on | Bundled or per endpoint |
| Best for | Businesses with IT oversight | Regulated industries, critical operations |
| Compliance value | High | Very High |
Our recommendation for most Kamloops and BC small businesses: At minimum, deploy EDR across all endpoints. If your business handles sensitive client data or has significant cyber insurance requirements, step up to MDR.
Either is vastly better than basic antivirus alone.
EDR, MDR, and Cyber Insurance in BC
One important consideration: BC businesses are increasingly required to demonstrate specific security controls to maintain cyber insurance. Many insurers now ask explicitly about:
- Whether you have EDR (not just antivirus) deployed
- Whether you have MFA on all privileged accounts and email
- Whether you have managed backup with tested recovery
- Whether you have 24/7 security monitoring (MDR helps here)
If your cyber insurance policy is up for renewal and you haven’t reviewed your security stack against these criteria, now is the time. Missing a required control can result in denied claims even when the policy is in force.
