Cybersecurity threats evolve rapidly, and if you think today’s encryption is enough, think again. As quantum computing advances, traditional encryption methods are at risk of becoming ineffective. That’s where Post-Quantum Crypto comes in. With that, the future of mobile app development companies is also changing. If your business relies on digital assets, whether a custom website, a SaaS platform, or a mobile app, it’s time to understand how crypto in web and app security is changing. And more importantly, how to future-proof your investments.
Let’s break it down for you.
This isn’t science fiction—it’s unfolding in real time. In 2023, IBM unveiled a 433-qubit quantum processor, a major leap in computing power. Around that time, Google disclosed that its quantum computer completed a complex task in only 200 seconds. The same task would have taken a classical supercomputer approximately 10,000 years to complete. These milestones mark the beginning of a new era where quantum computing could soon outperform classical systems in ways that directly impact digital security.
While quantum computing is still in its early stages, cybersecurity experts are unified on one point: it’s not a question of if, but when quantum machines will be capable of breaking today’s most widely used encryption standards. Algorithms like RSA and ECC, which currently secure everything from web traffic to financial transactions, will be rendered obsolete once quantum systems become more accessible and scalable.
Forward-thinking businesses are already preparing. A Deloitte report found that more than 50% of organizations plan to transition to post-quantum cryptography (PQC) by 2026. The urgency isn’t limited to tech companies; if your business collects user data, processes financial transactions, or operates in regulated industries like healthcare, fintech, or legal services, the quantum threat is highly relevant. Transitioning to quantum-resilient security measures now can save your business from costly vulnerabilities in the very near future.
Post-Quantum Cryptography (PQC) refers to a new generation of encryption algorithms specifically designed to be secure against both classical and quantum computing attacks. As quantum computers evolve, they will eventually be able to break many of the cryptographic systems currently in use. The goal of PQC is to replace these vulnerable systems with new ones that can withstand the immense processing power quantum machines are expected to deliver.
Most of today’s secure communications rely on algorithms like RSA and Elliptic Curve Cryptography (ECC). These work well against classical computers but are vulnerable to quantum algorithms such as Shor’s algorithm, which can efficiently factor large numbers and solve discrete logarithm problems, making it possible to break RSA and ECC encryption in a fraction of the time. In a post-quantum world, relying on these traditional methods could leave sensitive data—such as user credentials, financial transactions, or proprietary business information—wide open to compromise.
Researchers and cryptographers have developed several families of PQC algorithms that are resistant to quantum attacks. The leading approaches include:
Each of these methods addresses different cryptographic needs—ranging from encryption and key exchange to digital signatures—with the overarching goal of resisting both known and quantum-enabled attacks.
To address the rising urgency of the quantum threat, the United States initiated forward-looking measures. The National Institute of Standards and Technology (NIST) initiated a multi-year effort to assess and standardize cryptographic algorithms designed to withstand quantum attacks. As of now, NIST has selected a set of candidate algorithms that are undergoing final evaluation for inclusion in global cryptographic standards. These standards will shape the future of secure communication for governments, enterprises, and digital infrastructure around the world.
For business owners, this means now is the time to start understanding and planning for the transition to post-quantum security. Working with a forward-thinking web app development or app development company that tracks these standards ensures your systems remain secure both today and in the quantum-powered future.
As quantum computing capabilities advance, post-quantum cryptography (PQC) is becoming a critical part of web and app security architecture. Businesses developing digital platforms—whether customer-facing websites, enterprise dashboards, or mobile applications—must prepare now to protect their systems and data from future quantum-enabled threats. PQC is not a feature to be added later; it should be a foundational part of your development strategy moving forward.
If you’re building or upgrading web-based platforms such as customer portals, e-commerce sites, SaaS tools, or internal dashboards, post-quantum crypto in web app development should be integrated right from the design phase.
One key area of concern is HTTPS encryption, which relies on TLS (Transport Layer Security). While TLS is secure against conventional attacks today, future iterations will need to incorporate PQC algorithms to remain effective against quantum threats. This includes the cryptographic mechanisms used in key exchange protocols, session management, and secure API integrations.
According to the OWASP 2024 Security Report, nearly 70% of web applications still depend on RSA-based encryption, making them inherently vulnerable to quantum decryption methods. If your app handles sensitive customer information or financial data, sticking with legacy encryption models puts your entire business at risk in the coming years.
Mobile applications, especially in high-stakes industries like banking, healthcare, and logistics, are prime targets for future quantum-enabled attacks. Whether your app transmits patient health records, manages digital payments, or tracks delivery fleets, end-to-end encryption must be re-evaluated with PQC in mind.
Most mobile apps use digital signatures to verify updates and validate code integrity. These signatures must transition to post-quantum-secure algorithms to prevent unauthorized code injection or spoofing once quantum attacks become feasible. Failure to adapt could leave your app exposed to backdoors and malware posing as legitimate updates.
In this context, selecting an app development company that proactively understands and implements PQC standards is essential. It’s no longer just a best practice—it offers a strategic advantage in staying ahead of future threats. Businesses that begin the shift early will not only secure their platforms but also signal to users, investors, and regulators that they take security seriously.
Quantum computing is no longer a distant concern—it’s a fast-approaching reality that should influence every digital decision your business makes today. Whether you’re developing a platform from scratch or updating a legacy system, your strategy must account for emerging security challenges. Quantum-resilient security should be a core part of that strategy to ensure long-term protection.
Before you move forward with any web or mobile development project, it’s time to ask some critical questions. Are your developers using or exploring libraries that support post-quantum cryptography (PQC)? Many commonly used cryptographic libraries, such as OpenSSL or Bouncy Castle, are beginning to experiment with quantum-safe options. It’s important to know whether your current or prospective developers are keeping pace.
Also, is your web app development partner familiar with NIST’s PQC standardization process? NIST is actively working to finalize quantum-safe encryption protocols that will soon become the industry benchmark. If your development team isn’t aware of these standards, you risk falling behind and exposing your business to future vulnerabilities.
If you haven’t done so yet, start by auditing your application infrastructure to identify where cryptographic methods are being used. Identify all areas where encryption is applied, including data at rest, data in transit, and API authentication. Then assess whether these components rely on algorithms that are susceptible to quantum attacks. Complement this with a vulnerability assessment that evaluates your exposure to cryptographic threats.
Forward-thinking companies aren’t waiting for quantum attacks to become mainstream—they’re already designing quantum-resilient systems. These businesses are embedding post-quantum cryptography (PQC) into their product roadmaps and investing in team training. They’re also partnering with app development companies that grasp both the technical and strategic impact of this transition.
Preparing for the post-quantum era isn’t just the responsibility of tech giants. Any business that values data security, customer trust, and long-term resilience must take it seriously. Whether you’re operating an e-commerce site, a SaaS platform, or a mobile service, here are five essential steps to get quantum-ready.
Getting ready for the post-quantum era starts with pinpointing vulnerabilities in your current systems. Conduct a comprehensive audit to pinpoint where classical cryptography is currently being used. This should cover backend services, frontend web applications, APIs, mobile apps, third-party integrations, and cloud storage environments. Focus on components relying on RSA, ECC, or similar algorithms, as these will be the most vulnerable to future quantum threats. Once mapped, you’ll have a clearer picture of which systems need upgrading and where immediate action is required.
Security-first development partners will be key in future-proofing your digital assets. Partner with a company that provides webapp development services and prioritizes secure coding practices. Ensure they also stay up to date with emerging trends in post-quantum cryptography (PQC) to future-proof your digital solutions. The right partner should be familiar with quantum-resistant algorithms, be able to design hybrid systems, and have a roadmap for helping clients transition to PQC standards. Choosing a proactive team now will prevent rushed, expensive overhauls later.
Transitioning to PQC doesn’t have to be disruptive. A growing number of businesses are adopting hybrid cryptography, blending classical and quantum-resistant algorithms to ease the transition. This dual-layered approach ensures compatibility with existing systems while introducing quantum resilience into your security infrastructure. Hybrid cryptography is especially valuable during the transitional phase as post-quantum standards continue to evolve. It allows your systems to remain flexible while still maintaining strong security.
Your development and IT teams are on the front lines of implementation, so they must be equipped with the right knowledge. Offer training programs and workshops that focus on quantum-resilient standards, emerging cryptographic protocols, and NIST-approved algorithms. Regular upskilling not only keeps your teams current but also empowers them to make smarter, security-focused design decisions as your infrastructure evolves.
Stay informed by actively monitoring updates from authoritative bodies like the U.S. National Institute of Standards and Technology (NIST). NIST is currently leading global efforts to standardize PQC algorithms, and their recommendations will soon shape industry compliance requirements. Early adoption of these standards can help you avoid costly retrofits, regulatory penalties, and loss of competitive edge. Establish routine review cycles to keep your systems aligned with evolving security standards and maintain a competitive edge.
Quantum computing is no longer confined to research labs—it’s an inevitable shift that brings both serious risks and unique opportunities. Adopting post-quantum cryptography now can help your business prevent future data breaches and safeguard digital assets. It also builds long-term customer trust by demonstrating a proactive approach to security.
Whether you’re starting a new project or modernizing your technology stack, prioritize long-term security over short-term speed—build with the future in mind. Ready to build quantum-resilient apps? Partner with a company that provides web app development services and prioritizes next-generation security, and helps you lead with confidence, not just compliance.
