Traditional antivirus (Kaspersky, Bitdefender, Symantec) only catches known malware via signatures. EDR (Endpoint Detection and Response) flags suspicious behavior — including ransomware not yet in any database. After the 2023-2025 ransomware wave that hit Vietnamese businesses, EDR moved from nice-to-have to baseline.
Three options most common in Vietnam
- Microsoft Defender for Business: bundled with Microsoft 365 Business Premium — fits <300 users, no extra license
- CrowdStrike Falcon Go: ~USD 5-8/endpoint/month, cloud console, CrowdStrike threat intelligence
- SentinelOne Singularity Core: ~USD 6-9/endpoint/month, auto-rollback for ransomware
When Defender for Business is the right pick
If you already run Microsoft 365 Business Premium (~USD 22/user/month), Defender for Business is included — saving 60-80% versus a third-party EDR. It covers anti-phishing, anti-ransomware, web protection, and attack surface reduction. Sufficient for 80% of VN SMBs.
When to step up to CrowdStrike or SentinelOne
- Past ransomware or breach incident — you need deep threat hunting
- Specific compliance mandate (ISO 27001, PCI-DSS)
- Internal SOC that needs high-quality threat intelligence feeds
- 300+ endpoints and need for 24/7 Managed Detection and Response (MDR)
Digi43 distributes all three through manufacturer-approved channels — Defender for Business bundled with M365, and CrowdStrike and SentinelOne with volume pricing. Endpoint inventory assessment is complimentary.
