Opt Out of Zanshin Security Scanning

If you prefer to exclude your assets from Zanshin’s security scans, please contact us.


Tenchi Security will use this address to verify your request.Include the domain names and/or IP ranges, in CIDR notation, that you want excluded, along with a corporate email address.

Send your request to: asm-zanshin-opt-out@tenchisecurity.com

Before you submit

  • Requests are reviewed and processed within two business days of receipt.
  • Approved assets are removed from the scanning scope and excluded from all subsequent assessments.
  • The exclusion covers every subdomain of each domain listed and every address within each CIDR block listed.
  • Requests must be submitted by the asset owner or a representative formally authorized to act on their behalf.
  • A corporate email address is required; Tenchi Security uses it to confirm ownership and to communicate about this request.
  • The exclusion remains in effect until you ask us to reinstate scanning, which you may do at any time.

Please note: once excluded, these assets stop receiving security notifications from Zanshin. Vulnerabilities affecting them will no longer be detected or reported to you.
