Defender for Business —
questions answered
Q.What is Microsoft Defender for Business?
Microsoft Defender for Business is enterprise-grade endpoint security built for SMEs with up to 300 users. Included in Microsoft 365 Business Premium, it provides antivirus, endpoint detection and response (EDR), attack surface reduction, automated investigation, and threat and vulnerability management — replacing the need for a separate third-party antivirus product.
Q.Is Microsoft Defender for Business included in Microsoft 365?
Yes — Microsoft Defender for Business is included in Microsoft 365 Business Premium at no additional cost. It is also available as a standalone product. If your organisation is on Business Basic or Business Standard, you do not automatically have Defender for Business and would need to upgrade or purchase it separately. Coreitech can advise on the most cost-effective licencing route.
Q.How is Defender for Business different from Windows Defender?
Windows Defender (now called Microsoft Defender Antivirus) is the basic antivirus built into Windows. Microsoft Defender for Business adds enterprise-grade capabilities on top: endpoint detection and response (EDR), automated threat investigation, attack surface reduction rules, and the Defender portal for centralised management. It is significantly more powerful than basic Windows Defender.
Q.Can Coreitech manage Microsoft Defender for Business for us?
Yes. Coreitech provides fully managed Microsoft Defender for Business for London SMEs — including initial deployment, policy configuration, ongoing monitoring, alert triage, incident response, and monthly security reporting. We manage Defender from the Microsoft Defender portal so your team never needs to worry about security alerts.
Q.How long does Microsoft Defender for Business setup take?
For a London business with 10–100 devices, Coreitech typically deploys and configures Microsoft Defender for Business within 3–5 business days: device onboarding, policy configuration, ASR rules, and baseline security review. We can also migrate from a competing antivirus product as part of the deployment.
