Microsoft Defender for Business vs. ThreatDown

Microsoft Defender for Business is an AI-powered, enterprise-grade security solution tailored for small and medium-sized businesses (SMBs) with up to 300 employees. It offers comprehensive protection against cyberthreats such as ransomware, malware, and phishing attacks across various platforms, including Windows, macOS, iOS, and Android devices. Designed for ease of use, it provides robust security features without the need for specialized IT expertise.

AI has changed what businesses need to protect and how fast they need to respond. Ungoverned AI tools leak data through identities and API keys nobody's watching, while AI-driven attacks compress exploit windows from months to hours and generate the alert volume of dozens of attackers at once — a scale problem no team can staff its way out of. ThreatDown meets AI-scale risk with an AI-native platform built for more than the endpoint — one lightweight agent, one console, no tool sprawl. AI visibility flags every AI tool in use and blocks sensitive data before it reaches the model.
