VENDOR APPEAL GUIDE

Segasec false positive?
Here’s where to start.

Mimecast acquired Segasec in 2020. Mimecast now publishes a customer Support Center. This is a successor-company support route, not a verified dedicated appeal channel for the legacy Segasec label in VirusTotal.

How to request a review

Website / URL review

Mimecast acquired Segasec in 2020. Mimecast now publishes a customer Support Center. This is a successor-company support route, not a verified dedicated appeal channel for the legacy Segasec label in VirusTotal.

  1. Open Mimecast's Support Center or the Customer support section of its contact page.
  2. If you have customer support access, raise a case identifying the Segasec label and ask whether the team can review or route the report.
  3. Suggested details: the exact domain or URL, the VirusTotal report link, the detection date, and evidence of legitimate ownership and content.
  • Customer access may be needed to raise a case. No public commitment to process noncustomer appeals for legacy Segasec verdicts was found.
  • The acquisition does not by itself establish that the VirusTotal engine is retired.

Scope & contact notes

  • Listed in VirusTotal search-prefix documentation but absent from the contributor roster snapshot; this is not proof the engine is currently active.
  • This name appears in a VirusTotal engine-prefix list or contact table but is not matched to a current contributor entry. Current engine activity is unconfirmed.
