Endpoint Detection and Response: Catch Threats Before They Spread
Traditional antivirus software looks for known malware signatures - it misses the techniques attackers actually use today. Endpoint Detection and Response (EDR) software records everything happening on every device, spots suspicious behaviour in real time, and can automatically isolate a compromised machine before the threat spreads to the rest of your network. North Star deploys, configures, and manages EDR on every device in your environment as part of a managed security retainer.
Traditional antivirus looks for known malware signatures. Attackers figured out how to bypass signature detection years ago, by using living-off-the-land techniques, obfuscating their code, or using legitimate system tools in malicious ways. If your endpoint protection relies on signature-based detection, a skilled attacker can walk through it undetected.
Endpoint Detection and Response (EDR) takes a different approach. It records a continuous stream of activity on every device, process executions, file modifications, network connections, registry changes, and uses behavioural analysis to identify patterns that look like attacks, regardless of whether the specific malware has been seen before. When something suspicious happens, EDR can automatically isolate the device before the threat spreads.
North Star IT, based in Prince George, BC, deploys, configures, and manages EDR as part of a security retainer for businesses across British Columbia, Alberta, and Yukon. Your team does not need a full-time security analyst, ours handles it.
What Is the Difference Between EDR and Antivirus?
Legacy antivirus: compares files against a database of known bad signatures. Good at catching known malware; blind to novel threats, obfuscated code, and living-off-the-land attacks.
EDR: records all activity on the device and flags anomalous behaviour, a process spawning unexpected child processes, a script attempting to delete shadow copies, an application communicating with an unusual external IP. The detection is based on what is happening, not what the file is called.
XDR (Extended Detection and Response) extends this telemetry to include network traffic, email, and identity sources, giving a broader picture of an attack that spans multiple systems.
North Star manages the EDR/XDR platform, investigates alerts, and takes containment action. You get enterprise-level threat detection without hiring a security operations team.
What North Star Delivers
Deployment
Lightweight EDR agent deployed on every Windows, macOS, and server in your environment. Deployed remotely via your RMM platform, no site visits required for standard deployments.
Configuration
Detection policies tuned to your environment to reduce false positives while maintaining real detection capability. Exclusions documented and reviewed, we do not apply broad exclusions that undermine the protection.
24/7 Alert Monitoring and Response
All EDR alerts monitored and triaged. Real threats escalated and acted on immediately. Low-confidence alerts investigated and closed or escalated. Your team is notified of confirmed threats, not a stream of noise.
Device Isolation
When a confirmed threat is detected, the affected device is isolated from the network immediately, containing the threat before it spreads laterally. Isolation is documented and reversed after remediation is confirmed.
Threat Hunting
Periodic proactive searches for indicators of compromise that have not yet triggered an automated alert. Looks for persistence mechanisms, unusual scheduled tasks, and suspicious network connections that behavioural rules might not catch.
Monthly Reporting
Detection counts by category, confirmed threats, response times, and any indicators of compromise found. Trend over time so you can see whether your environment's threat profile is improving.
How It Works
Step 1, Deploy
EDR agent pushed to all managed devices via RMM. Coverage confirmed before the service is considered live.
Step 2, Tune
Detection policies adjusted for your environment. Initial false positives identified and resolved without creating broad exclusions.
Step 3, Monitor
24/7 alert monitoring and triage. Confirmed threats actioned immediately. Routine alerts resolved through documented runbooks.
Step 4, Report
Monthly summary of detections, response actions, and any recommendations for additional hardening based on what the EDR is seeing in your environment.
Who This Is For
- BC, Alberta, or Yukon businesses still running traditional antivirus who want to understand why that is not sufficient and what modern endpoint protection actually looks like
- Organisations whose cyber insurer is requiring EDR as a condition of coverage or renewal
- Businesses that have experienced an incident and want to know whether their current endpoint protection would have caught it
- IT managers who want professional 24/7 security monitoring without hiring an in-house security analyst
Why North Star IT
North Star is a Prince George-based cybersecurity provider serving businesses across Northern BC, BC, Alberta, and Yukon. EDR is only as effective as the team monitoring and responding to its alerts. We manage the platform, investigate every alert, and take containment action, so the technology actually does what it is supposed to do.
What buyers ask before they sign.
What EDR product does North Star use?
North Star uses enterprise-grade EDR platforms from leading vendors. The specific product depends on your environment size and requirements. We do not resell consumer-grade or entry-level products.
Does EDR replace our antivirus?
Yes. EDR includes the signature-based detection that antivirus provided, plus the behavioural monitoring layer. Running both simultaneously creates conflicts and is not recommended.
How is EDR managed - do we need a security team?
No. North Star manages the EDR platform on your behalf: deploying updates, tuning detection rules, investigating alerts, and taking containment action. You receive a monthly report summarising what was detected and how it was handled.
What is the difference between EDR and XDR?
EDR focuses on endpoint telemetry - laptops, desktops, servers. XDR extends that to email, network, and identity data sources, giving a unified view of an attack that may start with a phishing email, move laterally across the network, and ultimately compromise an endpoint. XDR is recommended for businesses with 25 or more users.
Will EDR affect the performance of our computers?
Modern EDR agents are designed to be lightweight. Most users notice no performance impact during normal work. Intensive processes like large file scans or video rendering may see a minor increase in scan time, but this is uncommon.
