Managed Detection and Response

Stay ahead of evolving threats

AI has raised the stakes on cybersecurity. AI-powered threats are more targeted, frequent, adaptive, scalable, deceptive and effective. You need AI-powered security on your side, to protect your organization and those who entrust you with their data.

Grant Thornton Managed Detection and Response pairs our proven risk analysis and strategy with CrowdStrike Falcon Complete agentic MDR. Our advisory, engineering and operational specialists operationalize security and deliver measurable outcomes that outperform legacy MDR and fragmented security operations.

We use AI agents to augment strategic analysis, automating high-friction workflows and scaling elite managed protection across your enterprise. With proactive threat hunting, automated response and ongoing platform optimization, we help you stop AI-driven adversaries, even as they move and adapt.

AI demands smarter application security

AI raises the speed and precision of attacks. Embed security in DevSecOps, protect models and strengthen governance to build audit-ready assurance.

Combining CrowdStrike with our capabilities

CrowdStrike provides a world-class security platform that our teams turn into a force multiplier. We integrate CrowdStrike Falcon Complete with our proven strategies, threat knowledge and operational rigor to deliver protection that goes beyond what technology or services can achieve on their own.

What this unlocks for our clients

Deeper, context-rich visibility

Falcon provides unified telemetry across endpoint, identity and cloud; our experts interpret that data, correlate subtle signals and surface threats that automated detection alone would miss.

Faster, professional-guided response

The platform enables rapid containment, and our team adds investigation, validation and root cause analysis to ensure threats are not only stopped but fully understood and remediated.

Proactive risk reduction

Falcon highlights exposures; our consultants prioritize them, translate findings into action and help clients harden their environment in ways that meaningfully reduce real-world risk.

AI acceleration with human judgment

Falcon’s AI speeds detection and triage while our analysts apply context, adversary knowledge and strategic decision-making to ensure accuracy and eliminate noise.

Security programs built for each client

Falcon’s modular design provides flexibility, and our team builds tailored programs that align with each client’s maturity, industry and threat landscape — ensuring technology and strategy work as one.

Continuous posture improvement

Falcon generates ongoing intelligence; we turn that into a continuous improvement cycle, tuning detections, refining configurations and evolving defenses as threats change.

Why this matters

Most providers either sell tools or sell services. We deliver the power of both — seamlessly integrated.

By combining the CrowdStrike platform with our consulting capabilities, clients gain:

Deeper visibility with expert interpretation
Faster response with guided remediation
Proactive hardening with strategic prioritization
AI-driven detection with human-driven decision making
A security program that evolves as the threat landscape changes

This is how we transform a leading security platform into a comprehensive, outcome-driven defense capability.
