Pulse is the product: 24/7 MDR in one console. Trace (exposure & vulnerabilities), Signal (threat intel) and Attest (compliance) are modules inside it: what Trace exposes, Pulse defends, Attest proves.

Managed detection and response run as a service: telemetry from endpoint, identity, cloud and network correlated in real time, triaged by named analysts, contained within SLA, around the clock all year.
Trace Exposure scans your perimeter and cloud from the outside. For everything else, Trace connects to the vulnerability scanners you already run, then de-duplicates, risk-ranks and tracks every finding to remediation, with maturity scoring your board can read.
Threat intelligence tuned to what you actually run. Register your stack and Signal filters the world's advisories down to the ones that touch it, with lookup and enrichment in the same console.
Compliance that runs on live platform evidence. Structured assessments against the frameworks you answer to, with exports your auditor, insurer and board can actually use.
