How can Darktrace balance increased threat detection accuracy with minimizing false positives?

Introduction

Balancing increased threat detection accuracy with minimizing false positives is a critical challenge for Darktrace's cybersecurity platform. This trade-off directly impacts the effectiveness of our threat detection capabilities and the user experience for our clients. I'll analyze this problem by examining the product ecosystem, key metrics, and potential experimental approaches to find an optimal balance.
