Why Securence (SolarWinds) appears in this category
Securence — SolarWinds email security service.
We classify it as a email security gateway from include: mechanisms in the SPF record matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
Securence is an email gateway and outbound transmission provider that handles message authentication and relay for organisations requiring managed email infrastructure. It operates within the SolarWinds security and infrastructure portfolio.
Securence appears in email authentication records as an SPF include across smaller and mid-market websites, predominantly in the .com domain space. Because SPF delegates sending permission to Securence's IP addresses, recipient mail systems evaluate Securence's gateway reputation as part of the authentication chain, meaning both Securence's and the sending domain's standing affect deliverability decisions.

SPF delegation and shared gateway reputation
When a domain includes Securence in its SPF record, recipient mail servers evaluate both the sending domain and Securence's reputation during authentication. If Securence's gateway IPs accumulate abuse complaints or trigger recipient filters, legitimate mail from smaller senders using Securence can be affected regardless of their individual sending practices. This creates both risk and benefit: smaller organisations depend on Securence's overall reputation whilst gaining the infrastructure advantages of a managed gateway.
