Post-quantum cryptography (PQC): 27% of businesses globally to deploy PQC by 2035, driven by crypto-agility

A new study by global tech strategist Juniper Research has found that the number of businesses deploying PQC algorithms will exceed 100 million by 2035 globally; representing meteoric growth from just 35,000 in 2026.

The study found that this dramatic growth will be driven by two main factors:

1. The alignment of global standards
2. The crypto-agile roll-out of PQC algorithms by key security vendors.

“Early adopters of PQC are deliberately choosing quantum-secure services, but as standards align, security vendors will increasingly offer quantum-secure solutions by default. Security vendors must move rapidly to establish PQC credentials, or they will be bypassed by faster moving specialists, as the implications of quantum become increasingly high profile,” explained VP of Research Nick Maynard.

Crypto-agility Vital to Success

The report identified cryptographic agility as vital to success for security providers. As the development of quantum computing still holds many uncertainties, preparing for a one-off shift to updated cryptographic algorithms is not sufficient.

Maynard commented: “Focusing on crypto-agility – meaning enabling organisations to quickly change their cryptography to meet new developments – is a key policy for keeping cryptography strategies flexible. This will enable organisations to invest in PQC now, without tying themselves down to a specific cryptographic deployment.”

Moving to a more agile approach will be complex; therefore, security vendors must focus on enabling businesses to shift their mindsets and processes to a more agile approach. The research urged organisations to create a priority list for transitioning different elements of their infrastructure to PQC; moving to quantum-safe cryptography depending on urgency.
