Why Forcepoint MailControl appears in this category
Forcepoint MailControl — enterprise email security.
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.
Forcepoint MailControl is a cloud-based email security and filtering platform operated by Forcepoint. It sits in the email gateway layer, scanning inbound and outbound mail for threats, enforcing compliance policies, and filtering spam and malware, typically deployed as a supplementary layer alongside a primary mail platform such as Microsoft 365.
Forcepoint MailControl's infrastructure footprint matters for both senders and recipients. The platform predominantly serves smaller and mid-market organisations globally, not the largest brands. For senders, this means an extra filtering layer — if Forcepoint's policies flag your message, it may be quarantined or rejected despite strong authentication. For recipients, understanding Forcepoint's configuration and quarantine procedures is critical to recover legitimate mail that might otherwise disappear.

Forcepoint MailControl as an Email Gateway Layer
Forcepoint MailControl operates as a mail gateway: all inbound and outbound email passes through its scanning infrastructure before reaching the final recipient. When you send to an organisation using Forcepoint, your message encounters Forcepoint's content rules, policy filters, and threat detection independently of the recipient's primary email system. If Forcepoint quarantines or rejects your message based on content, policy, or reputation checks, no amount of SPF alignment or DKIM signing will override the decision. Senders experiencing unexplained delivery failures to Forcepoint-protected recipients should investigate whether Forcepoint's gateway filtering—customised per customer—is the bottleneck, rather than assuming sender reputation or authentication is the root cause.
