Frequently Asked Questions
Qubit Guard is a quantum-safe cybersecurity platform that protects communications, APIs, VPNs, and user access using post-quantum cryptography (PQC). It is designed to defend against both today’s cyberattacks and future quantum-computer threats.
Adversaries are already performing “Harvest Now, Decrypt Later (HNDL)” attacks—stealing encrypted data today and storing it until quantum computers can break RSA and ECC encryption. Data with long confidentiality lifetimes (government, BFSI, healthcare) is already at risk.
Traditional tools rely on classical cryptography that quantum computers will break. Qubit Guard uses NIST-approved post-quantum algorithms (ML-KEM / Kyber – FIPS 203) and supports hybrid cryptography, ensuring protection during the transition to a post-quantum world.
Yes. Qubit Guard aligns with:
- PL 117-260(PQC migration by 2030)
- Executive Order 14144, as amended by EO 14306
- CISA’s requirementto identify PQC-enabled products by December 1, 2025
- NIST PQC standards (FIPS 203)
Qubit Guard offers a full-stack PQC security suite:
- Quantum VPN– quantum-resilient remote access
- QuantShield– PQC protection for APIs and application traffic
- Qubit Guard Messenger– patented hierarchical secure messaging
- Qubit Guard Meet– quantum-safe video conferencing
- CBOM Platform– Cryptography Bill of Materials and PQC migration intelligence
A CBOM is a complete inventory of all cryptographic assets across your organization—algorithms, keys, certificates, protocols, libraries, and dependencies. You cannot secure or migrate what you cannot see.
Qubit Guard:
- Discovers quantum-vulnerable crypto (RSA, ECDHE, ECC)
- Assesses risk using CBOM analytics
- Implements hybrid PQCwithout breaking existing systems
- Enables crypto-agilityfor future algorithm changes
No. QuantShield and Quantum VPN act as transparent quantum wrappers, securing traffic at the network and API layer without requiring application code changes.
Qubit Guard supports:
- On-premises
- Public or Private cloud
- Air-gapped environments
This ensures full data sovereignty and zero third-party access—critical for government, defense, and regulated industries
Qubit Guard is designed for:
- Federal, state, and local governments
- BFSI and insurance companies
- Healthcare and life sciences
- Defense, aerospace, and critical infrastructure
- Enterprises with long-term data sensitivity
Yes. Qubit Guard has supported deployments exceeding 1.2 million users, proving scalability for large government and enterprise environments.
Delaying PQC adoption increases exposure to:
- Long-term data compromise
- Regulatory non-compliance
- Legal and financial penalties
- Loss of public trust and national security risk
Organizations can begin with:
- A CBOM-based quantum readiness assessment
- A pilot deploymentusing hybrid PQC
- A phased migration aligned with NIST guidance

Common Objections — and Clear Answers
Quantum computers don’t exist yet. Why act now?
Objection:
Quantum threats are theoretical and years away.
Response:
The threat is not theoretical. Adversaries are already executing Harvest Now, Decrypt Later (HNDL) attacks—stealing encrypted data today and waiting to decrypt it once quantum capability matures. Any data with long confidentiality life (government records, financial transactions, healthcare data) is already compromised if it relies on RSA or ECC.
We already use AES-256. Aren’t we safe?”
Objection:
Strong symmetric encryption is enough.
Response:
AES-256 is considered quantum-resistant only for data at rest. The real weakness lies in key exchange and authentication (RSA, ECDHE, ECC), which quantum computers can fully break using Shor’s algorithm. If keys are broken, AES becomes irrelevant.
Post-quantum cryptography isn’t standardized yet.
Objection:
PQC is still experimental.
Response:
This is no longer true. NIST standardized ML-KEM (Kyber) as FIPS 203 in 2024. U.S. federal mandates already require agencies and vendors to prepare for PQC adoption. Waiting now increases compliance and security risk.
Won’t PQC slow down our systems?
Objection:
Post-quantum algorithms hurt performance.
Response:
Qubit Guard uses hybrid cryptography (classical + PQC), ensuring performance remains enterprise-grade while providing quantum resilience. In real deployments, latency impact is negligible compared to the cost of breaches, downtime, or regulatory penalties.
This sounds like ripping and replacing our infrastructure.
Objection:
Migration will be disruptive and expensive.
Response:
Qubit Guard is designed as a non-disruptive quantum wrapper. It secures VPNs, APIs, messaging, and video without changing application code. Migration is phased, risk-based, and aligned with NIST timelines.
We’ll wait until regulators force us.
Objection:
No immediate mandate, no urgency.
Response:
Regulators are already moving:
- PL 117-260mandates PQC readiness by 2030
- EO 14144 / EO 14306require CISA to identify PQC-enabled products by Dec 1, 2025
Waiting means rushed compliance, higher costs, and audit exposure.
How do we even know where cryptography is used?
Objection:
Crypto visibility is too complex.
Response:
That’s exactly why Qubit Guard provides a CBOM (Cryptography Bill of Materials). CBOM gives complete visibility into algorithms, keys, certificates, libraries, and protocols—making quantum risk measurable and manageable.
Public cloud security tools already protect us.
Objection:
Our cloud provider handles encryption.
Response:
Cloud providers manage their keys, not yours. This creates data sovereignty, compliance, and insider-risk concerns—especially for government, BFSI, and healthcare. Qubit Guard ensures customer-owned keys, on-prem or private-cloud control, and zero third-party access.
Isn’t this overkill for non-defense organizations?
Objection:
Quantum security is only for defense agencies.
Response:
BFSI, insurance, healthcare, and critical infrastructure hold data that remains sensitive for decades. Once breached, data cannot be “re-encrypted.” Quantum risk is industry-agnostic—impact is financial, legal, and reputational.
How is this different from other PQC vendors?
Objection:
Many vendors claim quantum readiness.
Response:
Most vendors sell algorithms or consulting.
Qubit Guard delivers a full-stack, patented PQC platform:
- VPN, API security, messaging, video
- CBOM-driven migration intelligence
- Proven deployments at million-user scale
- Sovereign, air-gapped-ready architecture
What’s the cost of doing nothing?
Objection:
Risk seems abstract.
Response:
The cost is permanent:
- Future decryption of today’s stolen data
- Regulatory non-compliance penalties
- Litigation and breach response costs
- Loss of public trust
Quantum attacks are one-way doors—once data is exposed, it cannot be fixed.
