    SnapComms is an Everbridge company; api.snapcomms.com is the baseURL of the SnapComms API
    documented on the Everbridge developer hub. Probed by hand 2026-08-27 because
    probe-domain-security.py resolves hosts from apis.yml and the primary OpenAPI servers only.

    Probed by hand 2026-08-27. No DS record, so DNSSEC is not enabled on snapcomms.com — unlike
    everbridge.com and everbridge.net, which both have it. Neither everbridge.com,
    everbridge.net nor snapcomms.com publishes a CAA record.
