Sigma Vulnerability Disclosure Policy

Sigma is committed to the security and protection of our products, services, customer data, and infrastructure. We recognize the value of engaging with external security researchers in identifying and mitigating security vulnerabilities.

We will appreciate a responsible submission if you believe you’ve found a security vulnerability in a Sigma Computing product. You can submit a detailed description of the issue to us, including the steps that we can take to reproduce the issue and/or a proof-of-concept (“Report”).

We ask that reporters honor responsible disclosure principles and processes while engaging with us in order for Sigma to evaluate, respond to, or remediate any confirmed security vulnerabilities before public or third-party disclosure.

Responsible Reporting and Disclosure

Sigma believes in responsible reporting and disclosure, and we ask the following:

  • Do not violate the privacy of other users, destroy data, or disrupt services
  • Promptly report the vulnerability to us and provide as much detail so we can reproduce the vulnerability.
  • Report the details of the security vulnerability to us without sharing any information of the vulnerability publicly.
  • Do not disrupt or degrade Sigma’s products and services.
  • Do not access, modify, destroy, or violate the privacy of any Sigma customer or data.
  • Comply with all applicable laws.
  • Avoid degradation of user experience, disruption to production systems, and any access, copying, destruction, or manipulation of data.
  • Once you’ve established that a vulnerability exists or encountered any of the sensitive data outlined below, you must stop your test and notify us immediately.
  • You will NOT be Executing, or attempting to execute, a denial of service attack.


This policy applies to all the products, services, and infrastructure developed, managed, and maintained by Sigma Computing.

  • Issues that require unlikely user interaction.
  • Testers will not modify or remove any accounts not added by the tester as multiple testers will be using the tenant / org.
  • Testers will not modify the “Authentication” page of any designated testing Org.
