Gigamon has announced new updates to its Deep Observability Pipeline, introducing support for post-quantum cryptography (PQC) in its latest GigaVUE 6.12 release. The development is aimed at helping organisations prepare for the security challenges posed by quantum computing, which could undermine existing encryption standards within the next decade.
As quantum technologies advance, analysts have warned that traditional public-key cryptographic methods may no longer be secure by 2030. This has prompted governments, researchers, and technology companies to begin transitioning to quantum-safe encryption standards. Gigamon’s update extends visibility into encrypted network traffic, allowing security teams to identify weak or outdated cipher suites and monitor the adoption of PQC across hybrid cloud environments.
Company security experts describe the growing threat of so-called “harvest now, decrypt later” attacks, in which threat actors capture encrypted data today with the intention of decrypting it in the future once quantum computing becomes more accessible. The new capability aims to give organisations insight into where and how cryptography is used within their infrastructure so they can act before vulnerabilities are exploited.
Gigamon’s platform provides what it calls deep observability — the correlation of network-derived telemetry such as packets, flows, and metadata with log data from existing security and monitoring tools. By integrating post-quantum cryptography support into this system, organisations can now identify non-compliant encryption methods, build cryptographic inventories, and verify the correct implementation of PQC algorithms.
The update includes support for TLS 1.3, the most widely adopted protocol for encrypted communications and the only current standard that supports post-quantum cryptography. Gigamon’s approach gives users the option to decrypt traffic or employ its Precryption technology, which allows visibility into plaintext data before it is encrypted, without using traditional “break and inspect” methods.
The company says the new functionality is designed to help Security and IT teams integrate cryptographic visibility with existing tools such as SIEM and vulnerability management platforms, enabling real-time alerts and compliance tracking for insecure or outdated protocols.
While many organisations are still in the early stages of preparing for the quantum era, industry surveys suggest a majority of IT leaders are already planning to adopt PQC. Analysts note that the urgency is rising as national security bodies and regulatory agencies begin mandating quantum-safe transition strategies to protect long-term data confidentiality.
Gigamon’s latest release positions the company among a growing field of vendors developing visibility and defensive tools to help enterprises manage the coming shift in cryptographic standards. The move reflects an increasing focus within the cybersecurity community on readiness for the post-quantum world — one where encryption, once considered unbreakable, may no longer be enough.
