Why Post-Quantum Cryptography Matters—Right on the Wire

At AppLogic Networks, we’ve built the capability to monitor and analyze network traffic on the wire—in real time—for compliance with post-quantum cryptography standards. This gives organizations a powerful lens into whether their encrypted traffic is truly future proof… or still exposed to the growing “harvest now, decrypt later” threat.

The Quantum Threat Is Closer Than You Think

Quantum computers won’t need to break encryption in real time to be dangerous. Nation-states and attackers can intercept and store encrypted data today, then decrypt it later once quantum capabilities mature. Sensitive corporate IP, customer data, or national infrastructure traffic may already be vulnerable.

Despite this, many organizations have little or no visibility into what encryption is being used in the actual traffic flowing across their networks.

AppLogic: Making PQC Visibility Actionable

Through 2024, networks saw major vendors like Google adopt PQC through their support of Kyber and then ML-KEM in Chromium-based browsers. Cloudflare recently announced all traffic to their servers being PQC compliant.

This kind of visibility helps teams:

• Identify legacy or non-compliant encryption in use
• Track migration progress to quantum-safe protocols
• Provide real-time reporting and assurance to stakeholders
• Enable policies to block or flag vulnerable sessions

Why This Matters for Telcos and Enterprises

Governments are starting to require quantum transition roadmaps. Enterprises and telcos that can demonstrate cryptographic hygiene with real network data will be ahead of the curve.

The ability to offer Post-Quantum Encryption Assurance as part of your managed services portfolio is a compelling differentiator in sectors like finance, healthcare, and defense.

With visibility into where classical encryption lives, network teams can prioritize upgrades like certificates, hardware appliances, or software libraries.

By spotting weak or outdated encryption, organizations can close doors that quantum attackers may one day use as an investment in long-term data protection.

Use Cases AppLogic Networks Unlocks by Post-Quantum Visibility

The ability to detect and analyze whether network traffic is post-quantum compliant opens up a range of high impact use cases across both telcos and enterprise environments. Here are some of the most valuable ways organizations can leverage this capability:

Telcos and managed service providers can introduce new, revenue-generating services by offering quantum encryption visibility and assurance to enterprise customers. This includes:

• Managed reporting on cryptographic compliance
• Alerts on downgraded or non-compliant sessions
• Recommendations for upgrading endpoints or certificates

This transforms quantum readiness from an internal IT concern into a marketable security differentiator, positioning providers as leaders in the transition to a quantum-safe infrastructure.

Security teams can integrate AppLogic’s insights directly into their SOC workflows. For example:

• Trigger alerts when deprecated cryptographic suites are used.
• Flag sessions that fail to negotiate post-quantum key exchanges.
• Detect legacy VPNs, mail servers, or APIs that silently use vulnerable encryption.

This turns passive observability into proactive threat detection and response, giving SOC analysts the tools to close high-risk blind spots before they’re exploited.

Zero Trust models depend on deep context awareness—who’s accessing what, from where, and how. By adding cryptographic posture to the mix, organizations can apply smarter policies:

• Block access from devices that don’t support PQC.
• Enforce PQC-only tunnels for sensitive workloads.
• Restrict classical encryption to sandbox or legacy zones.

This elevates Zero Trust from identity and access control to cryptographic compliance enforcement, without relying on endpoint declarations alone.

CISOs and compliance leaders are already being asked, “Are we quantum-safe?”. With visibility into traffic-level encryption, you can now answer that question with concrete metrics:

• What percentage of traffic is PQC-compliant?
• Which services or regions still rely on vulnerable crypto?
• How is PQC adoption progressing over time?

This visibility makes board-level reporting and regulatory submissions data-driven and defensible, instead of anecdotal or guesswork-based.

Certain categories of data—healthcare records, legal documents, intellectual property—need to remain confidential for decades, not just months. Organizations can use AppLogic to:

• Audit traffic that handles long-retention or high-sensitivity data
• Ensure these data flows are already protected using PQC
• Isolate and secure critical sessions before they’re exposed to future threats

This is vital for forward-looking enterprises that are building a “secure today, safe tomorrow” strategy.

The Immediate Need

Post-quantum cryptography isn’t just a distant security problem—it’s a business and operational imperative right now. AppLogic Networks gives telcos and enterprises a unique advantage: true visibility on the wire, where it counts most.
