Why Securence (US gateway) appears in this category
Minneapolis-based business-class email filtering.
We classify it as a email security gateway from primary MX record (lowest preference) matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
Securence is an inbound mail gateway appliance developed by SolarWinds that inspects inbound email for threats, spam, malware, and policy violations before messages reach recipient mailboxes. It operates at the MX layer, serving as the first point of contact for mail destined for protected organisations.
Securence deployments are concentrated among smaller-to-mid-market organisations, predominantly in the .com namespace, with a global presence tilted towards North America. For senders, this means many smaller-scale but geographically dispersed recipients may be protected by Securence's filtering; any rejection at the gateway prevents delivery from reaching the recipient's own server, making Securence's filtering posture a direct determinant of deliverability success.

Gateway-Layer Rejection and Final Delivery Decisions
Unlike mailbox-level filters that a recipient can override or review, Securence enforces its decisions at the gateway layer — before mail reaches the recipient server. A rejection, block list hit, or policy denial by Securence is terminal and unreachable by the recipient's administrator. This means senders must satisfy Securence's reputation and authentication checks as a hard requirement; delivery success depends entirely on whether the sending IP and domain credentials pass Securence's filters, with no opportunity for the recipient to intervene.
