Halo Surface Signal for External-Surface Risk
Halo Surface Signal is the Halo-developed 1-5 lens in every threat advisory. It estimates whether the affected technology is likely on an internet-facing path so teams can start exposure validation earlier.
It does not replace CVSS, EPSS, CISA KEV, or internal asset truth. It adds external-surface risk context that supports exposure validation and remediation prioritization.
