Traditional antivirus catches known threats. Modern attacks use fileless malware, living-off-the-land techniques, and zero-day exploits that antivirus simply cannot detect. EDR is the next evolution — here is why your business needs it.
Endpoint Detection and Response (EDR) represents a fundamental shift from reactive to proactive endpoint security. Traditional antivirus relies on signature databases — it can only detect threats it has seen before. Modern attacks bypass this by using fileless malware (malicious scripts that run entirely in memory), living-off-the-land attacks (abusing legitimate tools like PowerShell), and zero-day exploits.
EDR solutions like Microsoft Defender for Endpoint, CrowdStrike, and SentinelOne work differently. Instead of matching signatures, they continuously monitor endpoint behavior: process creation, file modifications, network connections, registry changes, and memory operations. When suspicious behavior is detected — such as PowerShell attempting to download and execute a remote script — EDR can automatically isolate the endpoint, kill the malicious process, and alert your security team.
For businesses using Microsoft 365 Business Premium or Microsoft 365 E5, Defender for Endpoint is included at no additional cost. CloudTechForce deploys and manages Defender for Endpoint across our entire managed IT client base, with 24/7 monitoring through our Security Operations Center. For clients requiring advanced capabilities, we also deploy CrowdStrike and SentinelOne with managed detection and response.
