Vulnerability disclosure policy

JLL is committed to partnering with our corporate real estate clients to see a brighter way. This includes the securing of our corporate systems and the protection of data entrusted to us by clients and partners. 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.

JLL does not operate a bug bounty program. By submitting a vulnerability, you acknowledge that you have no expectation of payment and that you expressly waive any future pay claims against JLL related to your submission.

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.

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 JLL will not recommend or pursue legal action related to your research. Should legal action be initiated by a third party against you for activities that were conducted in accordance with this policy, we will make this authorization known.

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.
• Physical testing (e.g. office access, open doors, tailgating), social engineering (e.g. phishing, vishing), or any other non-technical vulnerability testing.

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).
• Be in English, if possible.

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.
