Proofpoint Joins Joint Cyber Defense Collaborative

Public-private partnership will facilitate a holistic and synchronised approach to threat prevention, detection, and response 


SUNNYVALE, Calif., May 17, 2023Proofpoint, Inc., a leading cybersecurity and compliance company, today announced its membership in the Joint Cyber Defense Collaborative (JCDC). Formed in 2021 by the Cybersecurity and Infrastructure Security Agency (CISA), JCDC is a public-private cybersecurity initiative that unites cyber defenders from organisations worldwide. 

Through this partnership, JCDC and Proofpoint will share information with each other about the current and emerging threat landscape. JCDC will provide timely information related to current security vulnerabilities, exploits, and other cyber issues, as well as best practises for mitigation. Proofpoint, in turn, has a world-class threat research team that offers unique insights, while its email and network telemetry provide unparallelled visibility into threats.

“Proofpoint’s partnership with JCDC underscores our commitment for collaboration with the global cybersecurity community to advance our nation’s cyber resilience and apply our collective capabilities to solving cybersecurity challenges,” said Ryan Kalember, executive vice president of cybersecurity strategy for Proofpoint. “JCDC membership provides Proofpoint with an opportunity to bolster our practises and products with timely intelligence about emerging threats and vulnerabilities. We are thrilled to be part of this collaborative ecosystem and offer our expertise to JCDC—and at the same time advance our ability to protect our customers.” 

One of the additional benefits of JCDC membership is the ability to incorporate preliminary cyber threat data as well as subsequent findings into Proofpoint’s threat intelligence offerings and investigations methods. This information sharing will result in the ability to deploy protection faster and better. And through shared threat intelligence, Proofpoint, JCDC, and CISA will be well positioned to remain ahead of adversaries while protecting organisations with actionable insights.
