Securing the Quantum Era: Future-Proof Your Data and Infrastructure

SecuPi is the only encryption solution in the market that delivers post-quantum-ready encryption through plug-ins and enforcers that apply encryption transparently, without requiring any application, analytics, or AI code changes. Encryption is enforced outside the application logic, centrally and consistently, while applications continue to operate as-is.

Why post-quantum cryptography matters, and how SecuPi helps you prepare

Encryption has protected sensitive data for decades, but its cryptographic foundations are facing a new challenge. As quantum computing advances, the public-key algorithms widely used today may eventually become vulnerable.

This is no longer theoretical. National Institute of Standards and Technology (NIST) has made it clear: sufficiently powerful quantum computers could break many of today’s public-key encryption systems. Organizations that rely on long-term confidentiality: financial services, healthcare and governments, must prepare now.

Why transparent encryption is critical for post-quantum readiness

As organizations begin planning for post-quantum cryptography (PQC), many will fail, not because the cryptography is wrong, but because the operational model is unworkable.

Encryption and PQC implementations require application code changes. This happens because encryption is typically invoked by calling APIs, user-defined functions (UDFs), or SDKs directly from application or analytics code. Every such call requires developers to modify, test, and redeploy production systems.

For modern enterprises, this approach simply does not scale.

Operational systems, analytics platforms, and AI pipelines are often built and maintained by scarce development teams that are already fully allocated. Expecting those teams to refactor large codebases, sometimes across hundreds of applications and tools, turns PQC into a multi-year initiative that stalls or is abandoned entirely. As a result, encryption projects fail not on security grounds, but on operational reality.

This is why transparent, no-code encryption is foundational to any realistic PQC strategy.

SecuPi is the only encryption solution in the market that delivers post-quantum-ready encryption through plug-ins and enforcers that apply encryption transparently, without requiring any application, analytics, or AI code changes. Encryption is enforced outside the application logic, centrally and consistently, while applications continue to operate as-is.

By eliminating code changes:

• PQC adoption becomes operationally feasible
• Encryption can be deployed across legacy, cloud, and AI systems simultaneously
• Security teams, not developers, own and control cryptographic policy
• PQC migration timelines shrink from years to weeks

In the post-quantum era, encryption that requires code changes will not scale. Transparent encryption is not an optimization, it is a prerequisite.

How quantum computing impacts today’s encryption

Asymmetric encryption at risk

Protocols such as TLS, digital signatures, and key exchange rely on asymmetric encryption (RSA, ECC). These methods depend on mathematical problems that are infeasible for classical computers to reverse.

Quantum algorithms, such as Shor’s algorithm, could factor large numbers and solve elliptic-curve problems dramatically faster, potentially reducing attacks from billions of years to hours.

Symmetric encryption pressure
Symmetric algorithms like AES are more resilient, but not immune. Grover’s algorithm provides a quadratic speedup for brute-force attacks, effectively halving key strength. Maintaining security requires larger keys (e.g., AES-256 instead of AES-128), increasing operational overhead.

What is post-quantum cryptography (PQC)?

Post-quantum cryptography refers to algorithms designed to withstand both classical and quantum attacks. Rather than relying on factoring or discrete logarithms, PQC uses alternative mathematical foundations, including:

• Lattice-based cryptography: Security based on complex geometric problems
• Hash-based cryptography: One-way functions resistant to quantum reversal
• Code-based cryptography: Error-correction techniques adapted for encryption

These approaches form the basis of emerging quantum-resistant standards.

Why PQC matters now

One of the most serious risks is “harvest now, decrypt later.” Adversaries can collect encrypted data today and decrypt it in the future once quantum capabilities mature. This is especially dangerous for data with long retention requirements, such as PII, PCI, and financial records.

Governments and regulators are already acting:

• August 2024: NIST finalized its first PQC standards (FIPS 203–205)
• March 2025: HQC selected as an additional PQC algorithm
• By 2030: Federal systems must support quantum-safe TLS
• By 2035: National security systems are expected to use PQC algorithms

Preparing for the post-quantum era

A practical PQC readiness program includes four phases:

1. Preparation

Identify cryptographic usage, stakeholders, and long-term data exposure risks. Build an inventory of cryptographic assets and align migration goals.

2. Baseline assessment

Map where vulnerable algorithms (RSA, ECC) are used, which assets rely on symmetric encryption, and which are already quantum-resistant.

3. Planning and execution

Adopt NIST-approved algorithms, prioritize high-risk systems, and use hybrid cryptography (classical + PQC) to reduce disruption during migration.

4. Monitoring and evolution

Track standards, measure migration progress, and continuously reassess cryptographic posture as PQC matures.

Why encryption alone isn’t enough

During migration, and for long-lived sensitive data, encryption alone may leave residual risk. Tokenization provides an additional layer of protection by replacing sensitive values with non-sensitive tokens, reducing exposure even if cryptography changes.

How SecuPi helps you prepare for the quantum era

SecuPi provides a future-ready data security platform that combines encryption, tokenization, and fine-grained access control to reduce quantum risk today.

• Quantum-resilient foundation: Built on strong symmetric encryption and hashing algorithms that remain viable in a post-quantum world
• Hybrid cryptography support: Enables gradual adoption of PQC alongside existing cryptography
• Tokenization for risk reduction: Limits the blast radius of long-retained sensitive data
• Policy-based access control: Ensures data is decrypted only when explicitly authorized

Preparing for quantum threats isn’t about a single upgrade: it’s about building adaptable systems. SecuPi is designed to evolve alongside cryptographic standards, helping organizations protect sensitive data today while staying ready for what comes next.
