We do not maintain a presence on Twitter/X, LinkedIn, or any other social platform. If someone is reaching out to you claiming to be us on one of those, it is not us.

For vulnerability disclosures, please use the same address with the subject prefixed [security]. We aim to acknowledge within a week.
