Evolent Health Vulnerability Disclosure Policy
Evolent Health is committed to ensuring the security of the public, patients, physicians, and other clinical and administrative staff by protecting their information. The Evolent Health security team acknowledges the valuable role that independent security researchers play in Internet security. This policy is intended to give security researchers clear guidelines for conducting vulnerability discovery activities and to convey our preferences in how to submit discovered vulnerabilities to us. This policy describes what systems and types of research are covered under this policy, how to send us vulnerability reports, and how long we ask security researchers to wait before publicly disclosing vulnerabilities.
We encourage you to contact us to report potential vulnerabilities in our systems. Please review these terms before you test and/or report a vulnerability.
If you make a good faith effort to comply with this policy during your security research, we will consider your research to be authorized. We will work with you to understand and resolve the issue quickly, and Evolent Health will not recommend or pursue legal action related to your research. As a policy, Evolent Health does not offer compensation for reported issues.
Under this policy, “research” means activities in which you:
- Notify us as soon as possible after you discover a real or potential security issue
- Make every effort to avoid privacy violations, degradation of user experience, disruption to production systems, and destruction or manipulation of data.
- Only use exploits to the extent necessary to confirm a vulnerability’s presence. Do not use an exploit to compromise or exfiltrate data, establish persistent command line access, or use the exploit to pivot to other systems.
- Provide us a reasonable amount of time to resolve the issue before you disclose it publicly.
- Do not submit a high volume of low-quality reports.
Once you’ve established that a vulnerability exists or encounter any sensitive data (including personally identifiable information, financial information, or proprietary information or trade secrets of any party), you must stop your test, notify us immediately, and not disclose this data to anyone else.
The following test methods are not authorized:
- Network denial of service (DoS or DDoS) tests or other tests that impair access to or damage a system or data (e.g., Spam, Brute Force)
- Physical testing (e.g., office access, open doors, tailgating), social engineering (e.g., phishing, vishing), or any other non-technical vulnerability testing
- Destroying or corrupting, or attempting to destroy or corrupt, data or information
- Violating any laws or breaching any agreements to discover vulnerabilities

Reporting a vulnerability
Information submitted under this policy will be used for defensive purposes only – to mitigate or remediate vulnerabilities. If your findings include newly discovered vulnerabilities that affect all users of a product or service and not solely Evolent Health, we may share your report with the Cybersecurity and Infrastructure Security Agency, where it will be handled under their coordinated vulnerability disclosure process. We will not share your name or contact information without express permission.
We accept vulnerability reports via firstname.lastname@example.org Reports may be submitted anonymously. If you share contact information, we will acknowledge receipt of your report within 3 business days.
What we would like to see from you
In order to help us triage and prioritize submissions, we recommend that your reports:
Describe the location the vulnerability was discovered and the potential impact of exploitation.
- Offer a detailed description of the steps needed to reproduce the vulnerability (proof of concept scripts or screenshots are helpful)
- Please list any pertinent applications, programs or tools used to in the discovery
- Please state date and time testing took place
What you can expect from us
When you choose to share your contact information with us, we commit to coordinating with you as openly and as quickly as possible.
- Within 3 business days, we will acknowledge that your report has been received.
- To the best of our ability, we will confirm the existence of the vulnerability to you and be as transparent as possible about what steps we are taking during the remediation process, including on issues or challenges that may delay resolution.
- We will maintain an open dialogue to discuss issues.
- We do not offer bug bounties or compensation for reported issues.
Questions regarding this policy may be sent to email@example.com. We also invite you to contact us with suggestions for improving this policy.
