Tech giants Amazon, Microsoft, Google, IBM, and Apple pledged a combined $30-plus-billion cybersecurity investment following a White House meeting today with U.S. President Joe Biden.

After the cybersecurity-focused meeting, Microsoft CEO Satya Nadella tweeted that his company will spend $20 billion over the next five years to advance its own security products and services. He also pledged $150 million to improve U.S. government agencies’ security posture and expand cybersecurity training partnerships.

Meanwhile, Google announced a five-year,  $10 billion cybersecurity investment. This will include “expanding zero-trust programs, helping secure the software supply chain, and enhancing open-source security,” Google SVP of Global Affairs Kent Walker wrote in a blog post.

Additionally, the No. 3 cloud provider pledged to train 100,000 Americans for data analytics, privacy, and security jobs through its Google Career Certificate program. “The certificates are industry-recognized and supported credentials that equip Americans with the skills they need to get high-paying, high-growth jobs,” Walker wrote, adding that more than half of the graduates come from under-represented backgrounds in tech — specifically Black, Latinx, female, and veterans. So, in addition to helping fill the cybersecurity skills gap, this program should also help the industry fix its diversity and inclusion problem.

Amazon announced two new security initiatives after meeting with Biden. First, starting in October, the company will make cybersecurity training materials available to individuals and businesses. Amazon developed these materials internally to keep its employees and sensitive data safe.

Second, the cloud giant will offer some Amazon Web Services (AWS) customers a free, multi-factor authentication device designed to better secure their environments. In addition to multiple AWS accounts, customers can use their devices to access other token-enabled applications such as GitHub, Gmail, and Dropbox.

IBM said it will train 150,000 people in cybersecurity skills over the next three years and will partner with more than 20 Historically Black Colleges and Universities to establish cybersecurity leadership centers.

And Apple will establish a new supply chain security program that includes working with its 9,000-plus suppliers in the U.S. to drive multi-factor authentication, security training, vulnerability remediation, event logging, and incident response, according to the White House.

Biden convened the meeting with private sector executives and education leaders following a spate of high-profile cyberattacks against U.S. and global targets and skyrocketing ransomware demands. “Cybersecurity threats and incidents affect businesses of all sizes, small towns and cities in every corner of the country, and the pocketbooks of middle-class families,” the White House said in a statement, noting that nearly half a million public and private cybersecurity jobs remain unfilled, which worsens the problem.

Today’s meeting reinforces Biden’s commitment to cybersecurity — and working with the private sector to prevent future cyberattacks, said Marcus Fowler, Darktrace’s director of strategic threat. “That relationship needs to be as strong as possible,” he added, noting that Biden's decision to appoint Jen Easterly as director of the U.S. Cybersecurity and Infrastructure Security Agency (CISA) is another example of this.

Most recently, Easterly was the head of Firm Resilience and the Fusion Resilience Center at Morgan Stanley. And this private-sector experience matters because these security professionals “are living defense, not just the latest intel or how to do an offensive capability,” Fowler said.

The public sector can and should look to private security companies to help determine what defensive technologies can harden their networks and systems, he added.

“For cybersecurity, it doesn’t need to be an internal government R&D effort,” Fowler said. “There are a lot of very successful companies applying these in the private sector. Let’s not recreate the logic or the learning to have an impact on mission.”
