As quantum computing advances, security teams face growing pressure to prepare for a world where today’s encryption standards may no longer hold.
Gigamon’s latest release, GigaVUE 6.12, adds post-quantum cryptography (PQC) capabilities to its Deep Observability Pipeline, giving organizations and MSSPs a way to detect vulnerabilities, secure encrypted traffic, and prepare for quantum-safe standards without disrupting operations.
Tackling the “Harvest Now, Decrypt Later” Risk
Quantum computing brings both promise and risk. For cybersecurity teams, one of the most pressing concerns is the “harvest now, decrypt later” threat, where attackers steal encrypted data today and store it until quantum computers can decrypt it in the future. Gigamon’s new PQC support is designed to stop that.
Sarah Banks, Vice President of Product Management at Gigamon, told MSSP Alert, “The ‘Harvest Now, Decrypt Later’ threat involves adversaries capturing vast amounts of currently encrypted data, knowing that in the future, sufficiently powerful quantum computers could use algorithms like Shor’s to break today’s standard public-key encryption. Gigamon addresses this threat by integrating PQC support into the Deep Observability Pipeline without compromising on visibility.”
Banks explained that Gigamon’s GigaSMART TLS/SSL decryption capabilities play a critical role in maintaining visibility. “This means security tools like IDSs, firewalls, and analytics platforms continue to receive plain-text copies of data, allowing them to detect threats within encrypted tunnels,” she said. “It eliminates blind spots as organizations transition to PQC algorithms, helping identify and prevent harvest-now attacks before they succeed.”
She also emphasized the importance of maintaining visibility throughout the migration to quantum-safe encryption. “We help by enforcing security policies and supporting Zero Trust enforcement across classic and PQC-encrypted traffic,” Banks said. “For MSSPs, this continuous visibility ensures compliance, reduces complexity, and optimizes resources since decryption happens once and can be shared across tools.”
Seeing Where Encryption Lives
Visibility is the foundation of any security transition, especially when it comes to encryption. With GigaVUE 6.12, organizations can see where cryptography is used across their hybrid and cloud environments, which algorithms are in play, and where quantum-safe pilots are taking shape.
“Through GigaVUE 6.12, organizations can map cryptographic use across hybrid and multi-cloud environments to locate systems still relying on pre-quantum algorithms and identify where PQC pilots are underway,” Banks explained. She added that teams can also monitor PQC performance in real time, detect weak cipher suites or expired certificates, and ensure that new encryption methods don’t slow performance or create new blind spots.
Banks said Gigamon’s approach turns telemetry into actionable insights: “By turning network telemetry into actionable guidance, we help organizations make PQC adoption secure, efficient, and aligned with governance standards.”
Helping Organizations Transition Smoothly
Preparing for post-quantum cryptography isn’t just a technical change; it’s a strategic one. The first step is knowing where encryption is used and where it’s vulnerable. Banks said that Gigamon helps organizations start by building a cryptographic inventory. “Organizations need to identify all instances of cryptography within their environments to determine where changes are necessary,” she said. “Gigamon supports customers in this process by leveraging dashboards to pinpoint quantum-vulnerable cryptography present within their networks.”
Once vulnerabilities are identified, teams can focus their remediation where it matters most. “By continuously aligning with the latest cryptographic standards, Gigamon ensures deep observability and actionable insights,” Banks added. “That combination allows organizations to optimize network performance, sustain visibility, and maintain robust security as they transition to post-quantum cryptography and beyond.”
Gigamon’s new PQC features give enterprises and MSSPs a practical way to protect against cryptographic risks while preparing for quantum computing’s impact. By combining visibility, performance optimization, and centralized decryption, Gigamon’s Deep Observability Pipeline helps organizations future-proof their data security, ensuring they can defend against today’s threats and those just over the horizon.
