Vulnerability disclosure policy

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.

This policy applies to only fully JLL-owned and managed systems and services. Any service not expressly listed above, such as any connected services, are excluded from scope and are not authorized for testing. Additionally, vulnerabilities found in systems of our vendors fall outside of this policy’s scope and should be reported directly to the vendor in accordance with their disclosure policy (if any). If you aren’t sure whether a system is in scope or not, contact us at vulndisclosure@jll.com.

Though we may assist in development and maintenance of other internet-accessible systems or services, we ask that active research and testing only be conducted on the systems and services covered by the scope of this policy. If there is a particular system not in scope that you think merits testing, please contact us to discuss it prior to any testing. We will evaluate the scope of this policy over time.

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 JLL, 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 vulndisclosure@jll.com. Reports may be submitted anonymously. If you share contact information, we will acknowledge receipt of your report within 3 business days.

We do not support PGP-encrypted emails. 

Questions regarding this policy may be sent to vulndisclosure@jll.com. We also invite you to contact us with suggestions for improving this policy.
