Outreach and Engagements

Outreach is one of the Director DTSA’s top priorities because our success is dependent upon close collaboration with U.S. Government stakeholders, Congressional colleagues, as well as with industry and international partners. Outreach engagements are intended to promote awareness of DTSA’s mission and the critical role we play in advancing the implementation of the National Defense Strategy. We provide exporters the national security perspective on technology and information security’s impact on export controls.

If you would like to schedule a meeting with the DTSA, Director/Deputy Director or request a DTSA speaker at your event, please complete the outreach request form, then attach your request to an email addressed to the Director's Action Group.
