Vulnerability Disclosure Program

Introduction

The information on this page is intended for security researchers interested in responsibly reporting security vulnerabilities to the Zscaler security team.

Security requires transformation and there is no better way to transform a security program than to engage directly with our customers and users. It is that engagement, along with a strong belief in the collaboration with the security community, that is the key to maintaining a secure environment for all of our users. If you believe you've discovered a security vulnerability on or within a Zscaler product, service, or application, we strongly encourage you to inform us as quickly as possible. We ask that such vulnerability reports be kept private and researchers not make those public until we have resolved the issue.

In return, we will work to review reports and respond in a timely manner. Our bug bounty partner, Bugcrowd, will engage with you initially to triage your submission. Zscaler will not seek judicial or law enforcement remedies against you for identifying security issues, so long as you (1) comply with the policies set forth herein; (2) comply with Bugcrowd’s Standard Disclosure Terms; (3) do not compromise the safety or privacy of our users; and (4) do not destroy any sensitive data you might have gathered from Zscaler as part of your research once issues are resolved; and (5) agree to and comply with Zscaler's Confidentiality terms below.

Confidentiality

By engaging or participating in and/or submitting a security vulnerability to Zscaler, you agree to comply with the following confidentiality provisions.

“Confidential Information” means (i) all Zscaler information obtained during security testing or via your participation in the Zscaler Vulnerability Disclosure Program, (ii) all information disclosed to you in connection with the Bugcrowd Bounty Brief, and (ii) all submissions by you. You are not granted any rights in Zscaler’s Confidential Information or intellectual property by engaging in any testing or participating in Zscaler’s Vulnerability Disclosure Program.

Confidential Information does not include information that (i) is or becomes publicly available through no fault of your own and without breaching these provisions, (ii) is independently developed without use of or reference to Confidential Information, or (iii) is or becomes known by you from a source not bound by confidentiality restrictions.

Before engaging in any testing or submitting findings you agree (i) to hold Confidential Information in strict confidence, (ii) to protect such Confidential Information from unauthorized use or disclosure, (iii) to not disclose such Confidential Information to any third party including the public, (iv) to not use such Confidential Information for any purpose outside the scope of participating in Zscaler’s Vulnerability Disclosure Program, and (v) to notify Zscaler immediately upon discovery of any loss or unauthorized disclosure of Confidential Information. Notwithstanding the foregoing, you may disclose Zscaler’s Confidential Information to Zscaler or to Bugcrowd via the Bugcrowd partner portal.
