Proactive Threat Hunting & Accelerated Response: Beyond OverWatch

CrowdStrike’s OverWatch service promises 24/7 human-led threat hunting. But today’s cyber landscape requires deeper coverage, faster response, and AI-enhanced intelligence. Bulletproof’s Proactive Threat Hunting services, built on Microsoft’s global intelligence graph and enriched with our tailored Cyber Threat Intelligence (CTI), deliver unmatched visibility and accelerated incident response. 

OverWatch primarily focuses on endpoint activity. Bulletproof goes further, our Microsoft Defender Expertsanalyze data across endpoints, Office 365, cloud applications, and identity systems, proactively hunting for anomalies across every domain. This all-domain visibility ensures we detect threats that siloed endpoint-only approaches often miss.

Bulletproof combines proprietary CTI feeds with the scale of Microsoft Threat Intelligence, which ingests trillions of global security signals daily. As a long-standing MISA member and Microsoft Security Trailblazer Award winner, we stay ahead of evolving attacker techniques. Our analysts leverage AI-driven enrichment and contextual insights to accelerate hunts and reduce false positives, helping security teams focus on what truly matters.

When incidents strike, every minute counts. Automation within Microsoft Defender for Endpoint plays a critical role in dramatically reducing Mean Time to Respond (MTTR). Built-in automated remediation helps resolve threats at machine speed, eliminating the need for manual intervention in many cases.

Bulletproof’s SOC-2 certified, geo-diverse 24x7 SOC-as-a-Service builds on this foundation with continuous IOC/TI ingestion, daily auditing, and real-time enrichment to ensure analysts have the right context at the right time. By combining automation with expert oversight, we streamline incident handling and help customers drive down alert fatigue.

The result? Actionable alerts are reduced to a fraction per user per month, and MTTR has been consistently brought down to the low double-digit minutes — a significant improvement over traditional response times and a measurable business benefit.

While OverWatch offers a strong starting point for endpoint hunting, Bulletproof’s Proactive Threat Hunting services deliver broader domain coverage, AI-driven enrichment, and accelerated response at scale—ensuring organizations stay ahead of evolving cyber threats.
