The 2021 Thales HSE Survey reveals major weaknesses in securing data in motion. About 42% of organizations either do not encrypt or are unsure if they encrypt network data, while most rely on firewalls instead of dedicated encryption hardware. Seventy-three percent acknowledge quantum threats, yet 61% lack a defined strategy. Frequent patching and hardware updates remain common, increasing costs and risks. The study recommends adopting dedicated, crypto-agile encryption solutions with secure key management, centralized control, and separation of duties to ensure long-term data protection across evolving networks.
