Keeper Security has officially announced that its identity security and Privileged Access Management (PAM) platform is now quantum-resistant. To achieve this milestone, the company integrated the Kyber key encapsulation mechanism an encryption algorithm approved by National Institute of Standards and Technology (NIST) across its infrastructure. As a result, Keeper strengthens its zero-trust and zero-knowledge architecture while proactively preparing customers for the era of quantum computing.
Notably, Keeper built its reputation on adopting the industry’s most trusted encryption standards. Now, by embedding Kyber into its client-server communications, the company delivers dual-layered protection. In other words, it safeguards organizations from present-day cyberattacks while simultaneously future-proofing their data against emerging quantum threats.

Why Quantum Risk Demands Immediate Action
Although encryption standards such as RSA and Elliptic Curve Cryptography (ECC) remain effective against today’s adversaries, they were never designed to withstand quantum-scale computation. Once quantum machines become operational at scale, they will be capable of breaking traditional public key cryptography the very foundation of internet security.
Furthermore, the threat is not theoretical. Cybercriminals are already leveraging “harvest now, decrypt later” tactics, capturing encrypted data today with the intent to decrypt it once quantum capabilities mature. Consequently, sensitive information including financial records, healthcare data and intellectual property faces long-term exposure risks.
Recognizing this urgency, NIST finalized Kyber in 2024 as one of the first post-quantum cryptography standards and encouraged organizations to begin transitioning immediately.
Keeper’s Hybrid, Crypto-Agile Strategy
By implementing Kyber, Keeper reinforces its leadership in protecting privileged credentials, secrets and secure connections. At the same time, the company aligns with broader industry momentum, as platforms like Apple iMessage, Signal, Google Chrome and Cloudflare have also begun rolling out post-quantum protections.

“Public key cryptography, including RSA and ECC, still provides strong defense against modern threats, but quantum computing changes the rules,” said Dr. Adam Everspaugh, Cryptography Advisor at Keeper Security. “Keeper’s hybrid approach combines battle-hardened, elliptic curve primitives with Kyber’s lattice-based cryptography. This layered defense ensures customers remain protected against today’s attackers while also guarding their data from adversaries armed with quantum capabilities in the future.”
Importantly, Keeper designed its Kyber integration to be crypto-agile. This means the platform can quickly update cryptographic protocols while maintaining backward compatibility during software upgrades. Additionally, Keeper secures both client-server authentication handshakes and encrypted data tunnels in transit. Customers automatically receive quantum-resistant protection when upgrading to the latest release without requiring configuration changes or manual intervention.
“Cybersecurity cannot be reactive. Waiting for quantum computers to arrive before acting would leave organizations dangerously exposed,” said Darren Guccione, CEO and Co-founder of Keeper Security. “Keeper’s deployment of Kyber is about foresight – helping our customers build resilience that spans both the threats they face today and the seismic changes on the horizon. We are ensuring that sensitive systems, credentials and secrets remain secure for decades to come.”
Expanding Protection Across the Platform
Keeper has already activated Kyber-based encryption in its backend APIs and Keeper Commander, with mobile integrations rolling out soon. Meanwhile, the company continues phased deployment to ensure performance and scalability across its entire platform.
This advancement further strengthens Keeper’s longstanding compliance credentials, including SOC 2 Type II, ISO 27001, ISO 27017, ISO 27018, FedRAMP High Authorization, GovRAMP High Authorization and FIPS 140-3 validation. Ultimately, by embracing quantum-resistant cryptography today, Keeper positions its customers to remain secure well into the quantum future.
