What happens next

  1. 1

    We read the message and reply by email. There is no ticket number.

    For an assessment question, include the domain and your role so we know who we are speaking with.

  3. 3

    This form is not an emergency incident-response line. If you are dealing with an active breach, contact your incident-response provider or the relevant authority.

What to leave out

Do not send passwords, API keys, session tokens, exploit code, or personal information about another person. For a vulnerability in ZeroKai, describe the impact. We will arrange a private channel if we need more detail.

Your message

Include the domain and what you want to understand. A work email lets us confirm who we are speaking with.

Use a company address for product and support questions. A personal address is fine for a privacy request or a security report.

If you are reporting a vulnerability on your own, write Independent.

Include the country code if you are outside Japan.
