QuSecure’s Rebecca Krauthamer: Building quantum-resilient security for a dynamic digital future (video)

When Rebecca Krauthamer first began working in artificial intelligence, cybersecurity wasn’t her destination — it was a discovery waiting on the horizon.

“I studied AI at Stanford, and when you start training large models, you eventually hit the wall of today’s hardware,” she recalls. “I wanted to see what was on the other side of that wall, and that was quantum computing.”

That curiosity sparked a career pivot that would position Krauthamer at the forefront of the quantum security revolution. In 2018, she co-founded QuSecure, which provides quantum-resilient cryptography “anytime, anywhere, on any device.”

Her early work on a U.S. Air Force grant focused on preventing data from being decrypted by future quantum computers — a problem that few were thinking about at the time.

“For me, it was an opportunity to help build the foundation for a secure digital future,” she says.

From quantum curiosity to cyber resilience

At a time when quantum computing was still considered science fiction, Krauthamer and her team saw beyond the hype.

“People were talking about the threat of quantum computers and decryption,” she explains. “But what we realized was that securing against quantum wasn’t just about migration — it was about resilience.”

That realization led to QuSecure’s breakthrough in “cryptographic agility,” an approach that allows organizations to adapt encryption dynamically as threats evolve. This innovation has since influenced global cybersecurity frameworks, including recent SEC guidance on quantum-safe migration.

“We were early movers in orchestrated cryptographic agility,” Krauthamer notes, “and it’s incredibly rewarding to see that philosophy now becoming part of industry best practices.”

Her vision reframes cybersecurity as a living ecosystem — one that must constantly evolve to maintain trust. Rather than treating the next migration as an endpoint, she sees resilience as a continuous process: “The goal isn’t another one-time upgrade. It’s ensuring our cryptographic foundation can respond as fast as the threats do.”

Leading by example and opening doors

As a founder and CEO in a male-dominated field, Krauthamer has navigated familiar challenges.

“Like a lot of women, I walked into rooms where I was the only woman at the table,” she says. “But being in that space invited others in.”

By building visibility and representation at the leadership level, Krauthamer helped QuSecure attract more diverse talent.

“Just having someone in leadership who looks like them, who represents them, creates permission for others to see themselves there too,” she explains.

She credits her progress to mentors — both men and women — who made space for her in those rooms and encouraged her to bring others along.

“It takes a village,” she says. “Leadership isn’t just about arriving; it’s about lifting others as you climb.”

Mentorship, inclusion, and calling it out

Krauthamer’s advocacy for diversity, equity, and inclusion is grounded in awareness and accountability.

“Cybersecurity can be very male-dominated,” she says. “Creating change requires deliberate effort — calling things out when we see them, and helping others recognize their assumptions.”

She recalls a story shared by a mentor: a senior female executive at a conference was mistaken for someone’s assistant.

“It’s those everyday assumptions that reveal where the work still needs to happen,” Krauthamer says. “We can’t just notice them — we have to speak up.”

For her, mentorship means not only guiding women in the field, but also engaging allies to make the industry more equitable for everyone.

Looking ahead

Having just returned from meetings in Washington, D.C., Krauthamer sees a convergence between innovation and policy.

“In the last five years, we’ve seen the equivalent of 15 years of progress in quantum computing,” she says. “That acceleration means legislation and migration timelines must accelerate too.”

Quantum computers capable of breaking current encryption may still be years away, she notes — but the solutions must start now.

“Quantum-safe security isn’t science fiction anymore. The technology to protect data exists today — preferably, it should have existed yesterday.”

Beyond quantum, she believes the broader theme shaping cybersecurity’s future is adaptability.

“As AI continues to evolve, resilience has to become our guiding principle,” she says. “Static defenses won’t cut it. We need systems that can learn, respond, and adapt as quickly as the threats themselves.”

Krauthamer’s journey — from AI researcher to quantum entrepreneur — captures the spirit of modern cybersecurity leadership: visionary yet grounded, deeply technical yet profoundly human. Through her work at QuSecure and her advocacy for inclusion, she’s helping to ensure that the digital future is not only secure, but resilient, ethical, and accessible to all.
