IBM has added quantum-safe encryption to its enterprise storage lineup, especially the new IBM FlashSystem x600 series, to protect data from harvest-and-decrypt-later cyberattacks. These solutions use advanced cryptographic algorithms built to resist future quantum computing threats. They are expected to be available in March 2026.

Key aspects of this integration include:
- Secure storage systems: The new FlashSystem X600 uses the latest Flash Core Module 5 (FCM5), a specialized storage module to deliver Quantum Safe encryption for stored data
- Data protection: This technology protects data against future threats by enabling quantum-safe TLS, a protocol for encrypting data in transit, and safeguarding data at rest. It is designed for critical infrastructure, government, and finance sectors.
- IBM Z mainframe security: IBM Z16 and LinuxONE systems use quantum-safe technologies and algorithms to secure data at rest, in transit, and in use
- DataPower Gateway X4 is a new physical appliance that secures and automates hybrid workloads with built-in quantum-safe cryptography for long-term data protection.
- Quantum-safe portfolio: IBM provides tools such as IBM Guardian Quantum Safe (for tracking cryptographic use), Quantum Safe Explorer (for exploring quantum algorithms), and Quantum Safe Remediator (for deploying new cryptography).
These advancements are part of IBM's broader plan to offer crypto agility, helping businesses adapt to changing cryptographic standards. Building on these innovations, IBM is also focusing on the needs of businesses facing evolving security requirements.

Continuing its focus on advanced security, IBM has introduced the next-generation DataPower Gateway X for a high-performance security gateway designed for enterprises. It secures, integrates, and automates modern and hybrid workloads, featuring quantum-safe cryptography for long-term data protection against future threats.

The X4 appliance serves as a unified gateway to protect, control, optimize, and connect applications across on-premises, cloud, and hybrid environments.

Why Application Security Matters for Business Agility

Enterprise IT environments are becoming increasingly complex, spanning multiple clouds, data centers, and diverse architectures. At the same time, cyber threats are growing and becoming more advanced, including new risks to current encryption from future quantum computing.

To innovate efficiently and securely, organizations must share devices with strong visibility, governance, and control. Secure, scalable integration is essential for delivering digital experiences and enabling automation to enhance efficiency.

Without a modern approach to application security, organizations can slow innovation, face increased costs, and risk exposing critical assets to threats.

Enterprise-Grade Security With Quantum Safe Production

Protecting client assets is IBM's priority. DataPower Gateway X4 appliances deliver robust application security and integration services, combined with ease of use and a low cost of ownership features that have been established in DataPower solutions.

The gateway supports a unified security framework for on-premises, cloud, and hybrid environments. Placed at the network edge and in the DMZ, it blocks unauthorized access, helps prevent denial-of-service attacks, and optimizes traffic routing. With DataPower Virtual Edition, organizations can extend this protection to cloud deployments, ensuring consistent security across the entire environment. The gateway secures both traditional web services and modern workloads, including API-based apps, event-driven and streaming services using Kafka, gRPC, and GraphQL. In computing and IT security, IBM researchers developed cryptographic schemes that NIST adopted as standards to strengthen public key cryptography. DataPower Gateway X4 appliance includes post-quantum cryptography (PQC) capabilities that can be configured for both inbound and outbound connections using TLS server and client profiles. Hybrid cryptographic algorithms are also provided, combining quantum-safe and classical methods to balance security strength with performance. With IBM DataPower, organizations can confidently protect the WAN and optimize service delivery while reducing development effort and mitigating business risk.

These advancements are part of IBM's broader plan to offer crypto agility, helping businesses adapt to changing cryptographic standards. Building on these innovations, IBM is also focusing on the needs of businesses facing evolving security requirements.

Continuing its focus on advanced security, IBM has introduced the next-generation DataPower Gateway X for a high-performance security gateway designed for enterprises. It secures, integrates, and automates modern and hybrid workloads, featuring quantum-safe cryptography for long-term data protection against future threats.

The X4 appliance serves as a unified gateway to protect, control, optimize, and connect applications across on-premises, cloud, and hybrid environments.

Why Application Security Matters for Business Agility

Enterprise IT environments are becoming increasingly complex, spanning multiple clouds, data centers, and diverse architectures. At the same time, cyber threats are growing and becoming more advanced, including new risks to current encryption from future quantum computing.

To innovate efficiently and securely, organizations must share devices with strong visibility, governance, and control. Secure, scalable integration is essential for delivering digital experiences and enabling automation to enhance efficiency.

Without a modern approach to application security, organizations can slow innovation, face increased costs, and risk exposing critical assets to threats.

Enterprise-Grade Security With Quantum Safe Production

Protecting client assets is IBM's priority. DataPower Gateway X4 appliances deliver robust application security and integration services, combined with ease of use and a low cost of ownership features that have been established in DataPower solutions.

The gateway supports a unified security framework for on-premises, cloud, and hybrid environments. Placed at the network edge and in the DMZ, it blocks unauthorized access, helps prevent denial-of-service attacks, and optimizes traffic routing. With DataPower Virtual Edition, organizations can extend this protection to cloud deployments, ensuring consistent security across the entire environment. The gateway secures both traditional web services and modern workloads, including API-based apps, event-driven and streaming services using Kafka, gRPC, and GraphQL. In computing and IT security, IBM researchers developed cryptographic schemes that NIST adopted as standards to strengthen public key cryptography. DataPower Gateway X4 appliance includes post-quantum cryptography (PQC) capabilities that can be configured for both inbound and outbound connections using TLS server and client profiles. Hybrid cryptographic algorithms are also provided, combining quantum-safe and classical methods to balance security strength with performance. With IBM DataPower, organizations can confidently protect the WAN and optimize service delivery while reducing development effort and mitigating business risk.
