Rebecca PY Keeper Security has deployed quantum-resistant encryption across its platform using the NIST-approved Kyber algorithm to protect data against future quantum threats. The upgrade is automatic for customers and reinforces Keeper’s zero-trust, zero-knowledge security architecture.
SINGAPORE, 28 FEBRUARY 2026 – Keeper Security has announced that its zero-trust and zero-knowledge identity security and Privileged Access Management (PAM) platform is now quantum-resistant, marking a major step toward safeguarding sensitive data against emerging quantum computing threats. The company has integrated the Kyber key encapsulation mechanism across its platform, a post-quantum cryptography algorithm standardized by National Institute of Standards and Technology in 2024.
The move addresses growing concerns that current public key encryption methods such as RSA and Elliptic Curve Cryptography may be rendered ineffective once large-scale quantum computers become viable. This risk is amplified by “harvest now, decrypt later” attacks, where encrypted data is intercepted today and stored for future decryption using quantum technology, potentially exposing financial records, healthcare data and intellectual property years later.
Keeper’s implementation delivers dual protection by defending against present-day cyber threats while preparing customers for a post-quantum future. The platform adopts a hybrid cryptographic approach, combining established elliptic curve techniques with Kyber’s lattice-based cryptography, ensuring layered security without sacrificing performance or compatibility.
The quantum-resistant encryption is applied to both client-server authentication handshakes and encrypted data tunnels, reinforcing Keeper’s zero-trust architecture. The deployment is crypto-agile, allowing cryptographic protocols to evolve as standards mature, while remaining backward compatible during upgrades. Customers receive the enhanced protection automatically when updating to the latest version, with no configuration changes required.
Keeper’s adoption of Kyber aligns with broader industry momentum, following similar post-quantum initiatives by Apple iMessage, Signal, Google Chrome and Cloudflare. The company said the rollout is already live across its backend APIs and Keeper Commander, with mobile platforms to follow as part of a phased expansion.
The milestone further strengthens Keeper’s compliance posture, adding quantum resilience to its existing certifications, which include SOC 2 Type II, ISO 27001 and FedRAMP High Authorization.
