Important Guidelines: (Must Read)

  • Please ensure that the string "Bugcrowd-<BugcrowdUsername>" is appended to your user agent for all HTTP/HTTPS traffic before performing any testing. Example instructions on how to modify the user agent string for Chrome can be found here, and for Burp Suite can be found here.
  • Automated vulnerability scans are strictly prohibited (this includes any brute-force enumeration).
  • Maintaining confidentiality regarding any vulnerabilities you discover between ThousandEyes and yourself is crucial. Unauthorized disclosure can lead to removal from the Program and forfeiture of any reward.
  • At any point as a researcher, you are not allowed to modify/test any existing customer data or download any information other than from the Trial account or ThousandEyes grant to which you have been given access. Accessing/modifying any customer account or attempting to download customer data as part of vulnerability testing will lead to stricter actions, including termination and a ban from all Cisco programs, including ThousandEyes, given that these activities can not be considered researcher activities.
  • It's strictly forbidden to conduct any form of Denial of Service testing. If you identify a vector by which DoS can be performed, please get in touch with or submit a submission write-up.
  • Please note that as a bug bounty program participant, you play a crucial role in maintaining the security and availability of this live production environment.
  • This is a Private Program, so you must refrain from discussing program details, including Program name, scope, Vulnerability details, bounty structure, account information, or any other detail to anyone who is not a Bugcrowd employee or member of this Program. When collaborating with other Finders on the Program, do so securely, per the disclosure requirements listed in Bugcrowd's Code of Conduct.
  • Please clearly follow account creation guidelines for testing, including account naming and email conventions. Your submission may only be accepted if you adhere to those guidelines.


For the initial prioritization/rating of findings, this program will use the Bugcrowd Vulnerability Rating Taxonomy. However, it is important to note that in some cases, a vulnerability priority will be modified due to its likelihood or impact. In any instance where an issue is downgraded, a full, detailed explanation will be provided to the researcher, and the opportunity to appeal and make a case for a higher priority.
