SignQuantum, a post-quantum security provider for critical documents, officially launched its post-quantum cryptography solution designed to safeguard digitally signed documents from looming cybersecurity threats posed by quantum computing.
SignQuantum introduces a software add-on that integrates with e-signature platforms, allowing organizations to transition into the post-quantum era without overhauling existing workflows. The core of its innovation solves two of the most pressing challenges of digital signatures: ensuring authenticity and securing immutable proof of timing. It leverages the U.S. National Institute of Standards and Technology’s (NIST) primary-recommended post-quantum algorithm, and the quantum-resistant blockchain technology of QANplatform.
“SignQuantum seamlessly integrates with popular e-signature platforms, offering organizations a fast-lane to quantum-safe security without disrupting existing workflows,” said Nazmath Nazeer, CEO of SignQuantum. “SignQuantum uniquely solves two key challenges: maintaining digital signature authenticity and securing proof of timing by utilizing NIST’s primary-recommended post-quantum algorithm and quantum-resistant blockchain technology from QANplatform.”
SignQuantum’s product launch took place in Doha, Qatar, with (above pictured from left to right) Johann Polecsak, Co-founder and CTO of QANplatform; H.E. Sheikh Mansoor Bin Khalifa Al-Thani, Founder and Chairman of MBK Holding; and Nazmath Nazeer, CEO of SignQuantum.
The digital signature industry is experiencing a meteoric rise—currently valued at $10.8 billion in 2025 and projected to soar to $118.9 billion by 2032, with a compound annual growth rate (CAGR) of 40.9%. This surge is fueled by increased digital transformation, growing regulatory compliance demands, and the widespread shift to remote-first operations.
