The Growing Quantum Computing Threat

Britain’s National Cyber Security Centre (NCSC) recently issued a critical warning that businesses and governments must prepare for quantum computer hacking capabilities by 2035. As the NCSC stated, “The threat to cryptography from future large-scale, fault-tolerant quantum computers is now well understood.”
This warning underscores a vital concern for financial institutions: quantum computers will eventually be able to efficiently solve the complex mathematical problems that currently secure most public key cryptography protecting financial networks and data repositories today.
The NCSC is urging organisations to begin migration to quantum-resistant security measures, with adjustments starting as early as 2028 to avoid a potential “big panic” when the first practical quantum computers arrive. According to various industry surveys cited by the watchdog, organisational readiness for post-quantum cryptography remains “pretty low.”

Why Traditional Security Measures Will Fail

Financial institutions that delay preparation face several critical vulnerabilities:

  • Quantum Computing Threat: Within the NCSC’s predicted timeframe (by 2035), quantum-enabled attacks will be able to break RSA and ECC encryption currently protecting sensitive client information shared with financial service providers.
  • Single-Cloud Vulnerability: Financial institutions relying on a single cloud provider create an attractive single point of failure that sophisticated attackers could target once quantum capabilities advance.
    • Static Security Models: Traditional security focuses on perimeter defence rather than ensuring data integrity throughout the entire data lifecycle, both within client systems and when shared with financial service providers.
  • Client Trust Erosion: Without proper protection, a breach exposing client data could destroy decades of trust-building and severely damage institutional reputation.

Calimere Point + Prizsm Solution

Calimere Point’s Cloud-based data analytics platform, CPRA Cloud, has been specifically designed to support our clients across financial services and beyond to capture quantifiable value from improving the way they use their data. The integration with Prizsm reflects our commitment to ensuring that those clients who trust us with their sensitive data are protected from existing and emerging security threats through:

Quantum-Resistant Security: Protection against future quantum computing attacks ensures long-term data integrity for sensitive financial and non-financial data shared with CPRA Cloud, including client identifiers, activities, and portfolio information.

Immutable, Tamper-Proof Storage: Every client record shared with CPRA is cryptographically secured against unauthorised modification—providing complete confidentiality and protection for valuable client relationships.

Multi-Cloud Security Architecture: Data shared with CPRA Cloud is distributed across multiple secure environments, eliminating single points of failure that attackers might exploit—ensuring your sensitive client information remains protected.

Zero-Infrastructure Security: Comprehensive protection without the burden of managing complex security infrastructure allows our customers to focus on their clients rather than cyber security management.

Industry-First Security Validation: Prizsm is the only security solution to have successfully passed the rigorous UK Ministry of Defence Bug Bounty program, where elite ethical hackers attempt to breach the system. This unprecedented achievement demonstrates that data shared with our platform receives the highest level of protection available in the industry today.

AI-Resistant Protection: Beyond quantum threats, Prizsm’s security architecture is specifically designed to withstand sophisticated AI-powered attacks that can learn and adapt to traditional security measures. This dual-layer protection ensures shared data remains secure against both quantum and artificial intelligence threats on the horizon.

Seamless Integration: The CPRA Cloud + Prizsm solution integrates effortlessly with your existing systems architecture, requiring no disruptive changes to your current infrastructure. This means you can implement quantum-resistant security for shared data without costly overhauls or operational disruptions.

Real-World Impact

Financial institutions implementing CPRA Cloud + Prizsm for their data sharing can expect:

  • Complete protection of client identities and their associated activities when shared with financial service providers
  • Detection of attempted data manipulation within seconds rather than months
  • Maintenance of client trust through demonstrable security measures
  • Future-proofed protection against emerging quantum computing threats in line with NCSC recommendations
When the integrity of your shared client data determines the integrity of your business - CPRA Cloud + Prizsm: Quantum-grade security for a post-quantum world.
