David K. Firnhaber, PhD, a trailblazer in the realm of Post-Quantum Cryptography (PQC), has launched his new cybersecurity consulting firm, David K. Firnhaber, PhD. Kicking off today, February 1, 2025, and available here, this avant-garde firm offers groundbreaking solutions to combat the ever-changing cybersecurity landscape. With a keen focus on PQC, the firm is dedicated to protecting sensitive data from future quantum computer threats.


Two people collaborate in an office, analyzing code on a monitor. Papers with diagrams are on the wall. The mood is focused and engaged.

“This firm is the result of years of dedicated research and a passion for pushing the boundaries of cybersecurity,” said Firnhaber. “We aim to deliver rock-solid and forward-thinking cryptographic solutions to shield organizations in the quantum era.”


With the launch of David K. Firnhaber, PhD, the cybersecurity field takes a leap forward. The firm specializes in PQC, providing a spectrum of services, including vulnerability assessments, cryptographic system design, and consultancy for organizations eager to strengthen their security measures in anticipation of quantum computing advancements. Emphasizing resilience and innovation, the firm is poised to lead the charge in the cybersecurity industry.


David K. Firnhaber, PhD, brings an impressive array of expertise to his new venture. His dissertation, titled Post-Quantum Cryptography (PQC): Constructive Research in Quantum Simulations, explored various quantum computers and their qubit growth rates. Firnhaber's research published an insightful prediction on how many qubits are needed to crack modern RSA-2048 encryption, estimating the timeline for quantum computers to reach 1 million qubits—while noting that more than 1 million qubits might be necessary due to quantum gate complexity. He also delved into NIST's quantum-safe algorithms, such as Kyber CRYSTALS. Firnhaber's ultimate goal is to steer organizations toward the right solutions for their PQC concerns.


Currently, David K. Firnhaber, PhD, is also pursuing a second PhD in Cybersecurity, specializing in Governance, Risk, and Compliance. In addition to his consulting work, he serves as a professor at Ivy Tech Community College's School of IT in Lake County, Indiana. His vast knowledge and unwavering commitment to excellence make this consulting firm an invaluable ally for organizations preparing for the quantum horizon.
