Post-Quantum Security for Remote Access Systems

Post-Quantum VPN Encryption Is Becoming a Necessity, Not a Nice-to-Have Introduction Quantum computing is rapidly approaching a threshold that could render today’s internet encryption obsolete. While this threat may feel distant, experts warn it could arrive before 2030. In response, leading VPN providers are deploying post-quantum encryption to protect user privacy against both future quantum attacks and data being harvested today for later decryption. Why Quantum Computing Breaks Today’s Security • Modern VPNs rely on symmetric encryption like AES or ChaCha20 and public-key algorithms such as RSA and Diffie-Hellman. • Classical computers would need millions of years to crack these systems. • Quantum computers use qubits, enabling them to solve these cryptographic problems in minutes. • Public-key systems used during VPN handshakes are especially vulnerable and could be completely broken. • Attackers are already harvesting encrypted data now with plans to decrypt it later once quantum systems mature. What Post-Quantum Encryption Does • Post-quantum cryptography uses mathematical problems believed to be resistant to quantum attacks. • NIST standardized several quantum-resistant algorithms in 2022, including CRYSTALS-Kyber and related methods. • VPNs adopting PQE replace or augment vulnerable handshake mechanisms with these new standards. • This protects both current sessions and data intercepted today from future decryption. Which VPNs Are Leading • ExpressVPN offers PQE by default through Lightway and WireGuard using ML-KEM. • NordVPN supports PQE via its NordLynx protocol across most major platforms. • Mullvad enables quantum-resistant tunnels by default on WireGuard connections. • All rely on NIST-approved standards rather than proprietary cryptography. Trade-Offs and Limitations • PQE can slightly reduce speeds due to heavier cryptographic operations. • Compatibility issues exist with older devices and certain VPN features. • Not all servers or protocols currently support PQE. Why This Matters Quantum threats will fundamentally break today’s privacy infrastructure. VPNs that adopt post-quantum encryption now are protecting users not just from future attacks, but from today’s silent data harvesting. What is optional today will soon become mandatory, making early adoption a strategic security decision rather than a speculative upgrade.

Your encryption isn't being hacked. It's quietly expiring. Misconfigured. And being harvested — right now. 60% of organisations faced exploits tied to compromised PKI in 2025. 56% experienced disruptions from certificate failures. 114,000+ certificates. 4 full-time staff. This is today's baseline failure rate. PKI was built for closed networks and human-scale identities. That world ended. Cloud, IoT, agentic AI, and quantum are dismantling its foundations faster than most security teams realise. 7 structural failures your PKI audit isn't catching: Certificate sprawl — 81% of companies suffered outages. One failure at scale costs $5M+. The 47-day TLS mandate — By 2029, you'll renew ~2,100 certificates every single day. No manual team survives this. Fragile CA trust — One compromised root CA invalidates millions of certificates. Simultaneously. Zero visibility — 75% of organisations can't fully inventory their own certificates. Agentic AI — AI agents create ephemeral identities at millisecond velocity. PKI was never designed for this. Forrester predicts a major breach from agentic AI credential failure before end of 2026. Frozen IoT/OT hardware — RSA hardcoded into 20-year-lifecycle firmware. PKI cannot revoke it without physical replacement. No sovereign PKI — Indian banks, telecoms, and defence still depend on Western CA hierarchies. One geopolitical disruption = cascading failure. And then there's the threat PKI was never designed to survive. HNDL — Harvest Now, Decrypt Later — is already operational. Adversaries are intercepting your TLS traffic today and waiting for quantum capability to decrypt it. Data encrypted in 2026 could be readable by 2034. The Federal Reserve confirmed this as a present-day risk in 2025. NIST finalised post-quantum standards in August 2024. RSA and ECDSA will be deprecated by 2035. Yet only 5% of tech professionals have made quantum migration a near-term priority. Here's what most people miss: Switching to PQC algorithms is not enough. You've changed the locks. You haven't changed the key management vault behind them. The missing layer is a Quantum-Safe KMS — governing key lifecycle, seeding entropy via QRNG, sovereign on-premise deployment. PKI tells you who holds the key. QKMS governs the key's entire existence. The question every CISO should ask isn't "Are we quantum-safe?" It's: "Can we prove it to an auditor?"

Quantum computing is moving from "science fiction" to "business reality" faster than most predicted. Two recent papers have fundamentally shifted the timeline for when we need to care about Quantum-Safe security: 1️⃣ The "10,000 Qubits" Milestone: New research shows that we can execute Shor’s algorithm—the math that breaks today’s encryption—with far fewer resources than previously thought. By using reconfigurable atomic qubits, the hardware requirements for cracking RSA-2048 have dropped by nearly 20x. 2️⃣ The "9-Minute" Crypto Warning: Google’s latest whitepaper highlights a terrifying reality for digital assets. Under advanced quantum scenarios, the encryption protecting a cryptocurrency wallet could be cracked in under 10 minutes. This puts billions in "dormant" assets at immediate risk of "at-rest" attacks. The Bottom Line: The "Q-Day" window is shrinking. It’s no longer about if a quantum computer can break your encryption, but when your current migration timeline will run out. How do we respond? We can't just flip a switch on "Q-Day." For many organizations, becoming quantum safe is a multi-year journey. This is where Palo Alto Networks Quantum-Safe Security comes in. Instead of a manual, multi-year overhaul, we provide a path to Agentic Resilience: - Continuous Discovery: It automatically maps your "cryptographic bill of materials" (CBOM), identifying exactly where vulnerable RSA and ECC algorithms are hiding in your network. - Risk Prioritization: It correlates your encryption strength with business criticality, telling you exactly which high-value assets need to move to Post-Quantum Cryptography (PQC) first. - Real-Time Remediation: For legacy systems that can’t be easily upgraded, a "Quantum-Safe Proxy" re-encrypts vulnerable traffic into post-quantum algorithms (like ML-KEM) at the network edge. The transition to a quantum-safe future is a marathon, but the starting gun has already fired. Learn how to take your first steps at the link in the comments.

𝗪𝗵𝘆 𝗧𝗿𝗮𝗻𝘀𝗽𝗼𝗿𝘁 𝗘𝗻𝗰𝗿𝘆𝗽𝘁𝗶𝗼𝗻 𝗔𝗹𝗼𝗻𝗲 𝗜𝘀 𝗡𝗼 𝗟𝗼𝗻𝗴𝗲𝗿 𝗘𝗻𝗼𝘂𝗴𝗵 𝗳𝗼𝗿 𝗠𝗙𝗧 For years, Managed File Transfer security has been judged at the edges: Is the connection encrypted? Are files encrypted in transit? That view is no longer sufficient. Most MFT platforms rely on transport (TLS/SFTP) and payload (PGP) encryption to protect data entering and leaving the system, but this only covers part of the data lifecycle. Once files are inside the platform, they are parsed, queued, logged, stored, and routed across internal components. In many legacy MFT architectures, those internal paths rely on implicit trust and classical cryptographic assumptions that were never designed for long-term resilience. 𝗧𝗵𝗮𝘁’𝘀 𝘄𝗵𝗲𝗿𝗲 𝗿𝗶𝘀𝗸 𝗮𝗰𝗰𝘂𝗺𝘂𝗹𝗮𝘁𝗲𝘀. Even with strong edge encryption, many MFT systems:  • Trust internal components by default  • Encrypt data only at ingress and egress  • Rely on classical cryptography internally  • Lack crypto agility and granular enforcement This becomes a real governance issue and not a theoretical one. 𝗣𝗼𝘀𝘁-𝗤𝘂𝗮𝗻𝘁𝘂𝗺 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗥𝗲𝗾𝘂𝗶𝗿𝗲𝘀 𝗠𝗼𝗿𝗲 𝗧𝗵𝗮𝗻 𝗮 𝗖𝗶𝗽𝗵𝗲𝗿 𝗦𝘄𝗮𝗽 Post-quantum cryptography (PQC) isn’t just a future TLS upgrade. It exposes whether a platform was designed for end-to-end protection. 𝗔 𝗽𝗼𝘀𝘁-𝗾𝘂𝗮𝗻𝘁𝘂𝗺 𝗿𝗲𝗮𝗱𝘆 𝗠𝗙𝗧 𝗺𝘂𝘀𝘁 𝗮𝗽𝗽𝗹𝘆 𝘀𝘁𝗿𝗼𝗻𝗴 𝗰𝗿𝘆𝗽𝘁𝗼𝗴𝗿𝗮𝗽𝗵𝘆 𝗰𝗼𝗻𝘀𝗶𝘀𝘁𝗲𝗻𝘁𝗹𝘆:  • To data in transit  • To data at rest  • To internal service-to-service communication Anything less leaves gaps that time will eventually exploit. 𝗭𝗲𝗿𝗼 𝗧𝗿𝘂𝘀𝘁 𝗠𝘂𝘀𝘁 𝗘𝘅𝗶𝘀𝘁 𝗜𝗻𝘀𝗶𝗱𝗲 𝘁𝗵𝗲 𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺 PQC alone isn’t enough. A modern MFT platform must also enforce zero trust internally, not just at the perimeter. That means no implicit trust, explicit authentication everywhere, encrypted internal communication, flow-level policy enforcement, and full auditability. For CISOs, this is the difference between assuming security and being able to prove it. 𝗧𝗵𝗶𝘀 𝗶𝘀 𝗲𝘅𝗮𝗰𝘁𝗹𝘆 𝘄𝗵𝘆 𝘄𝗲 𝗿𝗲𝗱𝗲𝘀𝗶𝗴𝗻𝗲𝗱 𝗧𝗗𝗫𝗰𝗵𝗮𝗻𝗴𝗲 𝘃𝟱. TDXchange v5 was architected to move beyond edge-only security by:  • Supporting TLS, PGP or NIST-approved post-quantum cryptographic (PQC) encryption  • Encrypting data in transit and at rest, including internal datastores  • Enforcing zero-trust principles between internal components  • Eliminating implicit trust assumptions inside the platform The goal wasn’t another feature, it was an architecture that can defend sensitive data throughout its entire lifecycle, even as cryptographic threats evolve. 𝗘𝘅𝗲𝗰𝘂𝘁𝗶𝘃𝗲 𝗧𝗮𝗸𝗲𝗮𝘄𝗮𝘆 Transport and payload encryption are table stakes. In the post-quantum era, they are no longer enough on their own. Does your MFT protect data everywhere, or only at the edge? That distinction will increasingly determine which platforms remain defensible as post-quantum risk becomes operational reality.

Earlier this week, I had the privilege of speaking with Dorit Dor (דורית_דור), CTO at Check Point Software. With 30 years at the forefront of cybersecurity, Dorit embodies innovation and expertise in preventing cyberattacks. Our conversation explored groundbreaking topics like Quantum Computing, AI, and Emerging Cyber Threats. Dorit shared that Quantum Computing has the potential to revolutionise industries and solve some of humanity's greatest challenges. However, it also poses a significant risk to traditional encryption methods. Key Takeaways: 1️⃣ Record Now, Decrypt Later: Adversaries are already recording encrypted communications, planning to decrypt them once quantum computers are powerful enough to break RSA and ECC encryption. This is a critical threat for governments, financial institutions, and other organisations handling sensitive data. 2️⃣ Future-Proof Your Encryption: Organisations must prepare for a quantum-powered future by: 📍Reviewing encryption protocols: Identify vulnerabilities in current systems. 📍Adopting post-quantum cryptography: Technologies resilient to quantum attacks, like those integrated into Check Point Software's #VPN solutions. 📍Implementing encryption agility: Stay ahead by mapping out where encryption is used and prioritising high-risk areas. 3️⃣ Quantum Key Distribution (QKD): A cutting-edge solution that replaces traditional encryption keys with those generated through quantum technology, enhancing the resilience of key exchanges against future quantum threats. Navigating these challenges, organisations are facing the daunting task of identifying where encryption is applied and upgrading systems to meet post-quantum standards. The rise of the "dark web" and adversaries storing sensitive data for future decryption makes proactive measures non-negotiable. 🎯Call to Action - if your organisation handles sensitive files: 👉Review and upgrade your encryption strategy. 👉Embrace technologies like post-quantum cryptography and QKD. 👉Leverage tools like those from #CheckPointSoftware to secure your communications. 🎯For more information review the links below: 💡 Check Point Software - https://lnkd.in/e5YS-uFZ 💡 Wikipedia (Dorit Dor / דורית_דור) - https://lnkd.in/eHBD2q9v 💡 World Economic Forum - https://lnkd.in/ehhxEi2T 💡 RSAConference (resource material available under past contribution & Presentations) - https://lnkd.in/eyXNUZjk 💡 Cyber Threat Alliance - https://lnkd.in/ewnTDMJj 💡 Forbes Council - https://lnkd.in/egHKJT74 💡 DLD Conference - https://lnkd.in/eg_3Qsni 💡 Instagram - https://lnkd.in/eKxUHMJv Quantum computing is both a game-changer and a challenge.

𝗗𝗮𝘆 𝟴: 𝗗𝗮𝘁𝗮 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗮𝗻𝗱 𝗣𝗼𝘀𝘁 𝗤𝘂𝗮𝗻𝘁𝘂𝗺 𝗥𝗲𝗮𝗱𝗶𝗻𝗲𝘀𝘀 In today’s hyper-connected world, data is the new currency and the perimeter, and it is essential to safeguard them from Cyber criminals. The average cost of a data breach reached an all-time high of $4.88 million in 2024, a 10% increase from 2023. Advances in 𝗾𝘂𝗮𝗻𝘁𝘂𝗺 𝗰𝗼𝗺𝗽𝘂𝘁𝗶𝗻𝗴 further threaten traditional cryptographic systems by potentially rendering widely used algorithms like public key cryptography insecure. Even before large-scale quantum computers become practical, adversaries can harvest encrypted data today and store it for future decryption. Sensitive data encrypted with traditional algorithms may be vulnerable to retrospective attacks once quantum computers are available. As quantum technology evolves, the need for stronger data protection grows. Google Quantum AI recently demonstrated advancements with its Willow processors, which 𝗲𝗻𝗵𝗮𝗻𝗰𝗲𝘀 𝗲𝗿𝗿𝗼𝗿 𝗰𝗼𝗿𝗿𝗲𝗰𝘁𝗶𝗼𝗻 𝘂𝘀𝗶𝗻𝗴 𝘁𝗵𝗲 𝘀𝘂𝗿𝗳𝗮𝗰𝗲 𝗰𝗼𝗱𝗲. These breakthroughs underscore the growing efficiency and scalability of quantum computers. To address these threats, Enterprises are turning to 𝗮𝗴𝗶𝗹𝗲 𝗰𝗿𝘆𝗽𝘁𝗼𝗴𝗿𝗮𝗽𝗵𝘆 to prepare for Post Quantum era. Proactive Measures for Agile Cryptography and Quantum Resistance: 1. 𝗔𝗱𝗼𝗽𝘁 𝗣𝗼𝘀𝘁-𝗤𝘂𝗮𝗻𝘁𝘂𝗺 𝗔𝗹𝗴𝗼𝗿𝗶𝘁𝗵𝗺𝘀 Transition to NIST-approved PQC standards like CRYSTALS-Kyber, CRYSTALS-Dilithium, Sphincs+. Use hybrid cryptography that combines classical and quantum-resistant methods for a smoother transition. 2. 𝗗𝗲𝘀𝗶𝗴𝗻 𝗳𝗼𝗿 𝗔𝗴𝗶𝗹𝗶𝘁𝘆 Avoid hardcoding cryptographic algorithms. Implement abstraction layers and modular cryptographic libraries to enable easy updates, algorithm swaps, and seamless key rotation. 3. 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗲 𝗞𝗲𝘆 𝗠𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁 Use Hardware Security Modules (HSMs) and Key Management Systems (KMS) to automate secure key lifecycle management, including zero-downtime rotation. 4. 𝗣𝗿𝗼𝘁𝗲𝗰𝘁 𝗗𝗮𝘁𝗮 𝗘𝘃𝗲𝗿𝘆𝘄𝗵𝗲𝗿𝗲 Encrypt data at rest, in transit, and in use with quantum resistant standards and protocols. For unstructured data, use format-preserving encryption and deploy data-loss prevention (DLP) tools to detect and secure unprotected files. Replace sensitive information with unique tokens that have no exploitable value outside a secure tokenization system. 5. 𝗣𝗹𝗮𝗻 𝗔𝗵𝗲𝗮𝗱 Develop a quantum-readiness strategy, audit systems, prioritize sensitive data, and train teams on agile cryptography and PQC best practices. Agile cryptography and advanced data devaluation techniques are essential for protecting sensitive data as cyber threats evolve. Planning ahead for the post-quantum era can reduce migration costs to PQC algorithms and strengthen cryptographic resilience. Embrace agile cryptography. Devalue sensitive data.

Only 10,000 reconfigurable atomic qubits (https://lnkd.in/eXwBgNW3); if the results in the new paper from Madelyn Cain, Dolev Bluvstein & John Preskill hold, we need to stop treating post-quantum migration as a long-term roadmap item and start treating it as an emergency requirement across the entire stack. Modern cryptography is built on a specific engineering assumption: some problems are computationally intractable. That assumption underpins TLS, PKI, secure routing, financial systems, essentially everything that moves data. Quantum computing does not chip away at that assumption but it invalidates it for the systems we actually use. RSA and elliptic curves do not become “weaker”, they become solvable in a way that removes their security guarantees. The usual response is “we’ll move to PQC” eventually. That is necessary, but not sufficient. PQC replaces one set of hardness assumptions with another. Lattice-based, code-based, multivariate schemes are believed to resist both classical and quantum attacks, but they are still assumptions. We do not have the same level of long-term confidence we thought we had with factoring and discrete logs, and we already know how that story can go. If the failure mode you are protecting against is global cryptographic breakage, then “probably hard” is not the bar to aim for everywhere. Critical infrastructure, root keys, long-lived secrets, inter-datacenter links, anything with a long confidentiality horizon are not places to rely purely on unproven hardness assumptions, even if they are currently the best we have. We do have an alternative model: Quantum Key Distribution anchors security in physics, not computation. An eavesdropper is not “computationally limited”, they are physically detectable. That is a different security boundary. This is not a call to replace PQC with QKD. That would be unrealistic at scale today. It is a call to combine them properly. PQC should be deployed broadly because it scales and integrates with existing systems. QKD should be used on top where failure is not acceptable, to secure key exchange and establish trust in a way that does not depend on future algorithmic breakthroughs. A hybrid QKD+PQC architecture is not overkill. It is the only approach that addresses both known and unknown risks. The other point that gets ignored is timing. You do not migrate global cryptographic infrastructure quickly. These are multi-year, often decade transitions. By the time there is a clear case that current cryptographic systems are broken at scale, the opportunity to respond will have passed. The referenced paper suggests this risk horizon is rapidly approaching. So the relevant question is not “when will quantum computers break crypto.” It is whether you are comfortable designing systems today that assume they will not. Because if that assumption fails, everything built on top of it fails with it, and no one is prepared for that outcome.

Quantum Computing Isn’t a Future Threat—It’s Already Breaking Your Encryption “Google’s 2023 quantum experiment cracked RSA encryption in 15 seconds—a task that would take classical computers 300 trillion years. Your ‘unhackable’ data? It’s on borrowed time.” A Fortune 500 client discovered their “military-grade” VPNs were rendered obsolete overnight after quantum researchers leaked a blueprint to reverse-engineer RSA keys. Their fix? Post-quantum lattice-based cryptography—math so complex, even quantum machines choke. Quantum computing will rewrite security rules by: 1️⃣ Rendering RSA/ECC Encryption Obsolete (The algorithms securing 95% of today’s web) 2️⃣ Supercharging Brute-Force Attacks (Hackers could decrypt decades of stolen data retroactively) 2025 Reality Check: -> NIST’s Post-Quantum Standardization is racing to finalize quantum-resistant algorithms (CRYSTALS-Kyber is the frontrunner). -> China’s Micius Satellite already uses quantum encryption to send “unhackable” diplomatic messages. Inventory “Crypto-Debt”: Use tools like OpenQuantumSafe to flag systems reliant on RSA/ECC. Test Hybrid Systems: AWS KMS now supports quantum-safe keys paired with traditional AES-256.
