Amit Yoran, who ushered cybersecurity company Tenable into the public market as chief executive, died on Friday. He was 54.
Yoran’s passing was confirmed by Tenable in a Saturday press release. While the company said his death was unexpected, Yoran went on medical leave early last month as he battled cancer.
Funeral details have not yet been announced, the company said on Saturday.
Yoran took the helm of Tenable in 2016, his latest leadership role in the cybersecurity field. He previously served as president of RSA Security from 2014 to 2016. Yoran founded and led NetWitness as CEO between 2006 and 2011 before it was acquired by RSA, according to his LinkedIn page.
His decadeslong career in cybersecurity also included government and nonprofit work. Yoran was National Cybersecurity Director for the U.S. Department of Homeland Security from 2003 to 2004. He sat on the board of the Center for Internet Security since 2019.
Two years into Yoran’s tenure, Tenable went public on the Nasdaq. At the time, the IPO was seen as a success story for cybersecurity companies on Wall Street.
Yoran called the company’s focus on the vulnerabilities of businesses’ technology as unique in the market, while also noting its successful shift to a subscription model. By 2018, Yoran said, more than half of Fortune 500 companies were Tenable customers.
“We’ve become one of the most trusted and beloved brands in cybersecurity,” he told CNBC at the time of Tenable’s IPO. “Only the best and highest-performing private companies have the opportunity to go public. And that gives us a spot on a much larger stage to be able to tell our story.”
Tenable CFO Steve Vintz and Chief Operating Officer Mark Thurmond have acted as co-CEOs since Yoran went on medical leave in December. They will continue sharing the role while its board of directors looks for a permanent successor, the company said.
Yoran had expected his leave to last only a few months and said his condition was a “treatable situation,” according to a note to employees published on his LinkedIn page. He had “complete trust” in Vintz and Thurmond to lead the company in his absence.
“We have much to do and there is no time to waste,” Yoran wrote. “As I take a brief pause to prioritize my health, I will stay as connected as I can while giving myself the space to heal fully. I am deeply grateful for each of you, not only for the dedication you bring to your work but for the sense of community we’ve built together.”
Yoran was also the chair of Tenable’s board, a position that now will be held by Art Coviello, the company’s lead independent director. In a statement, Coviello called Yoran an “extraordinary” leader, colleague and friend.
“His passion for cybersecurity, his strategic vision, and his ability to inspire those around him have shaped Tenable’s culture and mission,” Coviello said. “His legacy will continue to guide us as we move forward.”

Oracle shares jumped more than 5% after a recent filing showed a cloud deal that would add over $30 billion annually.
CEO Safra Catz is slated to share the deal news at a company meeting Monday, according to a filing with the Securities and Exchange Commission. The revenues are expected to start hitting in the 2028 fiscal year.
“Oracle is off to a strong start in FY26,” Catz is expected to say, according to the filing. “Our MultiCloud database revenue continues to grow at over 100%, and we signed multiple large cloud services agreements including one that is expected to contribute more than $30 billion in annual revenue starting in FY28.”
The deals revealed Monday by Catz will not affect the company’s 2026 guidance, according to the filing.
U.S. President Donald Trump announced on April 4 that he would again postpone enforcement of a law banning TikTok unless its Chinese owner ByteDance divests from the platform.

U.S. President Donald Trump told Fox News in an interview aired on Sunday that he has a group of “very wealthy people” ready to buy TikTok, whose identities he can reveal in about two weeks.
Trump added that the deal will probably need Beijing’s approval to move forward, but said “I think President Xi will probably do it,” in reference to China’s leader Xi Jinping.
The president made the off-the-cuff remarks while discussing the possibility of another pause of his “reciprocal” tariffs on Fox News’ “Sunday Morning Futures with Maria Bartiromo.”
Tiktok’s fate in the U.S. has been in doubt since the approval of a law in 2024 that sought to ban the platform unless its Chinese owner, ByteDance, divested from it. The legislation was driven by concerns that the Chinese government could manipulate content and access sensitive data from American users.
Earlier this month, Trump extended the deadline for ByteDance to divest from the platform’s U.S. business. It was his third extension since the Supreme Court upheld the TikTok law just a few days before Trump’s second presidential inauguration in January. The new deadline is Sept. 17.
TikTok went dark in the U.S. ahead of the original deadline, but was restored after Trump provided it with assurances on the extension.
Trump, who credited the app with boosting his support among young voters in the last presidential election, has maintained that he would like to see the platform stay afloat under new ownership.
However, it’s unclear if ByteDance would be willing to sell the company. Any potential divestiture is likely to require approval from the Chinese government.
A deal that would have spun off TikTok’s U.S. operations and allowed ByteDance to retain a minority position had been in the works in April, but was derailed by the announcement of Donald Trump’s tariffs on China, Reuters reported that month.
NVIDIA founder and CEO Jensen Huang speaks during the NVIDIA GTC Paris keynote, part of the 9th edition of the VivaTech technology startup and innovation fair, held at the Dôme de Paris in the Porte de Versailles exhibition center in Paris on June 11, 2025.
About $500 million worth of sales occurred over the last month as the market notched new highs and shook off geopolitical tensions that had rattled investors, according to the report. The stock is up more than 17% this year despite concerns over curbs limiting AI chip sales overseas and 44% over the last three months.
Securities filings revealed that the tech titan recently unloaded about $15 million worth of shares as part of his more than $900 million plan announced in March to sell up to 6 million shares through the end of the year. Huang’s net worth totals about $138 billion, placing him as 11th on the Bloomberg Billionaires Index.
Last week, the chipmaking giant hit a fresh record and rallied for five straight days following the stock sales and an annual shareholder meeting, where the CEO called robotics the biggest opportunity for the company after AI. That helped the chipmaker regain its seat as the most valuable company ahead Microsoft and Apple.
The FT article cited a report from VerityData, which noted that the jump in shares above $150 prompted the stock dump.
Last year, Huang unloaded more than $700 million in Nvidia shares as part of a prearranged plan.
A Nvidia spokesperson declined to comment on the report.
