Maintain and expand the distributed honeypot network, analyzing telemetry for exploitation and new adversary techniques

Improve detection accuracy and reduce false positives using claims insights, external datasets, and vulnerability research

Publish advisories, research, and briefings that inform security decisions

Participate in the on-call rotation for emergency notifications
