In a Microsoft Build understandably dominated by the transformative viability of AI agents in the business world, nestled among all the agent-oriented announcements was one with quiet, earth-shattering potential for the future of cybersecurity for organisations: the launch of post-quantum cryptography (PQC) algorithms.
PQC refers to encryption methods designed to withstand attacks from quantum computers. Traditional cryptographic algorithms, which are essential to modern business communications and collaboration, as well as data storage and financial transactions, can be easily broken by quantum machines. As a consequence, these next-gen protocols Microsoft is offering aim to secure data and comms in a future where quantum computing is mainstream to ensure long-term privacy and protection across IT and UC systems.
Although PQC capabilities will only be available in preview for select customers and their developer teams for now, this update might represent the spark that lights the fire of the future of UC and collaboration cybersecurity resilience as bad actors become ever more sophisticated, and the technology needed to combat them needs to become ever more revolutionary.

What Exactly are Quantum Computing and Post-Quantum Cryptography?
Quantum computing is all set to shake up the tech world, and IT leaders need to be ready. Instead of using bits that flip between 0 and 1 like today’s computers, quantum machines use qubits, which can hold multiple states at once thanks to a property called superposition. Even more powerful is entanglement, where qubits become linked in ways that let them solve problems together, no matter how far apart they are.
What does that mean in real terms? Quantum computers can crunch through incredibly elaborate calculations at speeds that make classical computers look sluggish. That opens doors to breakthroughs in everything from drug discovery to logistics.
But there’s a terrifying catch. Quantum computing could blow traditional encryption wide open, which is a colossal red flag for IT and UC leaders. The security systems we rely on today won’t hold up in a post-quantum world. As this tech matures, we must rethink how we protect data and ensure secure collaboration across networks.
Enter PQC.
PQC is the development of cryptographic algorithms that can resist the gargantuan processing power of quantum computers. Traditional encryption methods rely on mathematical problems, such as factoring large numbers, that are hard for classical computers to solve but remarkably easy for quantum machines.
PQC takes a different approach, using hard problems from areas like lattice-based cryptography, hash functions, and error-correcting codes. These are problems that are believed to be resistant to both classical and quantum attacks. These algorithms are designed to secure communications, data, and authentication protocols in a future-proof, quantum-resilient capacity.
