Hans Vestberg and Jeff Greene are not publicly confirmed as business partners, colleagues or direct collaborators. Their clearest documented connection comes from the 2024 Salt Typhoon telecommunications cyberespionage response: Vestberg was then CEO of Verizon, while Greene was the Cybersecurity and Infrastructure Security Agency’s Executive Assistant Director for Cybersecurity.
Reuters placed both men in the same Salt Typhoon story in December 2024, but in different roles. Vestberg was reported to have attended a November 22 White House meeting with telecommunications executives, while Greene was speaking publicly about the government’s effort to remove attackers from compromised networks. That shared incident context does not establish that the two men personally worked together.
There is also an important identity point. The Jeff Greene relevant here is the former CISA cybersecurity official, not the billionaire real-estate investor of the same name, and not Jeff Green, the cofounder and CEO of The Trade Desk.
What connects Hans Vestberg and Jeff Greene?
The connection is Salt Typhoon, the name widely used for a major campaign targeting U.S. telecommunications infrastructure.
In a November 13, 2024 joint statement, the FBI and CISA said PRC-affiliated actors had compromised multiple telecommunications companies. The agencies said the attackers had obtained customer call-record data, private communications involving a limited number of people involved in government or political activity, and certain information connected with U.S. law-enforcement requests.
Verizon later confirmed that its network had been accessed. In its January 10, 2025 Salt Typhoon update, the company said it had worked with federal law-enforcement and national-security agencies and had contained the activity.
Vestberg was leading Verizon during that period. Reuters reported that he took part in a November 22, 2024 White House meeting involving telecommunications executives and the cyber intrusion.
Greene, meanwhile, was one of the senior federal cybersecurity officials addressing the incident publicly. In December 2024, Reuters reported via Channel NewsAsia that Greene said officials could not give a timetable for the “full eviction” of the attackers from affected networks.
Those facts put Vestberg and Greene in the same public-policy and cybersecurity story. They do not show a direct working relationship between the two men.
Which Jeff Greene is involved?
The relevant Jeff Greene is a U.S. cybersecurity and national-security policy specialist.
CISA announced Greene as Executive Assistant Director for Cybersecurity in July 2024 after a period in an acting capacity. Before that, he held senior roles across government, technology policy and cybersecurity.
In 2020, the National Cybersecurity Center of Excellence at NIST announced Greene as its director. His career also includes work at the National Security Council, Symantec and congressional homeland-security committees.
That background matters because it separates him from another well-known Jeff Greene, the Florida-based billionaire investor and real-estate developer. The Salt Typhoon connection concerns the cybersecurity official.
There is another similarly named technology executive: Jeff Green, without the final “e”, is cofounder and CEO of The Trade Desk. He is also a different person.
Hans Vestberg’s role at Verizon
Vestberg is a Swedish telecommunications executive whose career has been closely tied to large communications networks.
He spent nearly three decades at Ericsson and served as the Swedish company’s president and CEO from 2010 to 2016. Official Ericsson records differ over whether his career there began in 1988 or 1991, so the precise start year is best left unresolved.
Vestberg joined Verizon’s senior leadership in 2017 and became CEO in 2018. He added the chairman’s role in 2019.
His tenure coincided with Verizon’s large investment in 5G and network capacity. In a June 2025 Fast Company interview, Vestberg discussed Verizon’s roughly $52 billion commitment to spectrum acquired in a 2021 U.S. government auction.
He described spectrum, the radio frequencies used to carry wireless communications, as essential to Verizon’s long-term capacity. The interview also noted that Verizon’s share price had underperformed the broader market over the period following the spectrum purchase, giving useful context to the scale and risk of that strategy.
Vestberg stepped down as Verizon chairman and CEO on October 4, 2025. Verizon’s leadership-transition announcement said he would remain as a special adviser through October 4, 2026.
As of October 1, 2026, that advisory period was still in effect, but it was due to expire three days later. He was no longer a Verizon director by then.
Outside Verizon, Vestberg remained active in corporate and advisory roles. BlackRock lists him as a director, while Consello lists him as a Senior Operating Advisor. He also took 2026 roles connected with Digi Power X and US Data Centers.
Jeff Greene’s cybersecurity career
Greene’s route into cybersecurity was rooted more in policy and government than in telecom operations.
In a 2020 NIST profile, Greene described his move into cybersecurity as emerging from congressional policy work. His career subsequently crossed government, private-sector technology and cyber-policy institutions.
After his NIST role, Greene served at the National Security Council as chief for cyber response and policy. He later worked on cybersecurity policy at Aspen before moving into CISA leadership.
That made his role during Salt Typhoon very different from Vestberg’s. Vestberg was responsible for a major commercial network operator that had been affected; Greene was part of the federal cybersecurity apparatus responding to the broader national threat.
Greene is no longer at CISA. As of October 1, 2026, CSIS listed him as a non-resident senior associate, while Civira Partners identified him as a cofounder.
Did Hans Vestberg and Jeff Greene work together directly?
There is no public confirmation of a direct Vestberg-Greene partnership, joint project or personal working relationship.
It would therefore be inaccurate to say Greene advised Vestberg, that the two jointly led the Salt Typhoon response, or that they met during the November 2024 White House session. Reuters reported Vestberg’s participation in that meeting, but Greene’s attendance there has not been established.
The more precise description is that their professional responsibilities intersected around the same national cybersecurity incident. Verizon was one of the telecommunications companies responding to network compromise, while CISA was part of the federal response.
Why the names are easy to confuse online
The pairing has become harder to interpret because some recent web pages use the wrong Jeff Greene.
A number of articles published in 2026 have treated Vestberg and the cybersecurity official as figures connected through Salt Typhoon. Others have instead paired Vestberg with Jeff Greene, the billionaire real-estate investor, creating a completely different story around business careers and investments.
Those are not two versions of the same relationship. They involve two different men named Jeff Greene.
For readers searching for “Hans Vestberg and Jeff Greene” in connection with Verizon, CISA or Salt Typhoon, the relevant person is the cybersecurity specialist.
Where they are now
Vestberg left Verizon’s top job in October 2025 and, as of October 1, 2026, was nearing the scheduled end of his one-year special-adviser arrangement with the company. He remained involved in board, advisory and technology-infrastructure roles outside Verizon.
Greene had moved from federal cybersecurity leadership into private-sector and policy work, including Civira Partners and CSIS.
Their careers continue in adjacent areas of technology, infrastructure and cybersecurity, but the public record supports a specific and limited connection between them: the Salt Typhoon response put a major telecom chief executive and a senior federal cyber official into the same national-security story. It does not establish a personal or business partnership.
