Key FeaturesWhat is Microsoft Defender for Business, and could it suit your Business?
Small and Medium Enterprises (SMEs) form the backbone of the Bangladeshi economy and play a crucial role in the supply chain. However, in today's digital era, this significance also brings challenges. SMEs are increasingly targeted by malicious actors due to a fiercely competitive market and limited budgets for security measures, unlike larger corporations.
Over recent years, SMEs have embraced cloud technology for their operations, which has enhanced flexibility and mobility, positively impacting our daily lives. Yet, this shift has altered the risk landscape, emphasizing the importance of Endpoints and the necessity for a Zero Trust Architecture. The traditional notion of 'trust, but verify' is outdated, especially in light of current global events.
As Endpoints gain prominence and attackers become more sophisticated, conventional Endpoint protection methods like antivirus software fall short. SMEs often struggle to afford Enterprise-grade features such as Endpoint Detection and Response (EDR) and Threat and Vulnerability Management. However, the introduction of Microsoft Defender for Business aims to address this issue, offering SMEs a more accessible solution.

NIST Cyber Security Framework Alignment
Defender for Business encompasses functionality across all five key functions outlined in the NIST Cyber Security Framework
Identify
Threat & Vulnerability Management provides asset visibility, intelligent assessments, and built-in remediation tools for various platforms, including Windows, macOS, Linux, Android, iOS, and network devices. It prioritizes vulnerabilities on critical assets and offers security recommendations for risk mitigation.
Protect
Attack Surface Reduction helps reduce the attack surface by constraining certain software behaviors that could compromise devices or networks. Next Generation Protection complements the built-in Microsoft Defender Antivirus with additional functionality such as behavior-based, heuristic, and real-time AV protection.
Detect
Endpoint Detection & Response (EDR) offers advanced attack detection capabilities in near real-time. Security analysts can efficiently prioritize alerts, gain visibility into breach scopes, and take response actions to mitigate threats.
Respond
Auto Investigation & Remediation (AIR) utilizes various inspection algorithms and processes akin to those used by security analysts. AIR examines alerts and promptly takes action to resolve breaches, thereby reducing response times and minimizing damage.
Recover
Defender for Business supports recovery through automated remediation capabilities that restore affected systems and files. The solution helps organizations quickly return to a secure state after a security incident.
