Top Biden administration officials in homeland and cybersecurity this week met in San Francisco with senior business leaders in the technology space to strengthen cooperation in the area of cybersecurity.

“We are taking proactive steps to elevate our operational cooperation with the private sector to new heights, prioritizing our share goal of defending a secure digital future,” Homeland Security Secretary Alejandro Mayorkas said in a statement.

Mayorkas was joined by White House National Cyber Director Chris Inglis, Cybersecurity and Infrastructure Security Agency (CISA) Director Jen Easterly, and Rob Silvers, under secretary for policy at DHS, at the meeting Tuesday with the Silicon Valley leaders.

Technology companies represented at the meeting were AT&T [T], Broadcom [AVGO], Cisco [CSCO], Cloudflare [NET], Google [GOOG], Juniper Networks [JNPR], Lumen Technologies [LUMN], Mandiant [MNDT], Microsoft [MSFT], Palo Alto Networks [PANW], Recorded Future, SecureWorks [SCWX], Tenable [TENB] and VMware [VMW].

DHS said the discussions were aimed at improving operational collaboration and defining metrics of success. CISA recently established the Joint Cyber Defense Collaborative, which brings together key government and private sector organizations to work on operationalizing cyber collaboration and defense.

“Our strategy is to operationalize our industry partnerships to protect our critical infrastructure from cybersecurity threats,” Silvers said in a statement. “Yesterday’s discussion with industry leaders was an opportunity to hear from them about what they need from the government to do so and how we can better work together toward our shared goals.”
