# Post-Quantum Encryption: The Future Must-Have VPN Feature The new way to protect your data against quantum computers. - **Source:** [Lifehacker](https://brifing.si/source/f1400ced-a26b-4e58-a567-6187eca3708d) - **Published:** 2026-07-15 - **Original article:** - **On Brifing:** https://brifing.si/s/8176ed64-65b3-4510-a50d-983753c56167 ## The Threat of Quantum Computers Quantum computers are predicted to break current encryption techniques in the near future, creating a threat known as 'Q-Day.' Encryption protocols like RSA and ECC, used in VPN technology, will become insufficient. ## What is Post-Quantum Encryption? Post-quantum encryption (PQE) uses complex mathematical puzzles that even quantum computers struggle to solve. This technology was developed to protect VPN users' data against the Q-Day threat. ## HNDL Attacks and Risks Attackers are collecting encrypted data through 'harvest now, decrypt later' (HNDL) attacks. Once quantum computers are powerful enough, this data can be decrypted. PQE is a crucial safeguard against future risks. ## NIST Standards and Algorithms In 2024, NIST standardized new encryption algorithms resistant to quantum computers. Algorithms like ML-KEM, ML-DSA, and SLH-DSA offer effective solutions against such attacks. ## VPN Providers Supporting PQE Popular VPN providers like NordVPN, ExpressVPN, and Mullvad offer PQE features. This functionality can be easily enabled to protect users' data against quantum computer threats. ## The Encryption Technology of the Future PQE is a significant investment for those handling sensitive data or conducting high-value transactions. As quantum computers become more prevalent, this technology will become indispensable for VPN users. ## Sources covering this story - https://lifehacker.com/tech/post-quantum-encryption-vpn?utm_medium=RSS — --- _Summary written by Brifing from the original reporting.
