Fortinet & Lumen: Securing 2027 from Quantum Threats

With quantum computing getting closer and cyber threats getting worse, our current cryptographic standards are on borrowed time. The work being done on Fortinet PQC and by Lumen security teams is a serious move to get ahead of the problem, especially for protecting critical infrastructure from future quantum attacks. So how are these two industry heavyweights actually getting their strategies in line to build a more secure digital world?

The Quantum Threat and Cryptographic Agility

The idea of a quantum computer breaking today’s public-key algorithms like RSA and Elliptic Curve Cryptography (ECC) isn’t just theory anymore. While a fully fault-tolerant quantum machine is still years away (thankfully), the “harvest now, decrypt later” attack model is a present-day danger. This means an attacker can siphon off your encrypted data today, sit on it, and then decrypt it all once a powerful enough quantum computer exists. We have to get proactive about security, and that means focusing on Post-Quantum Cryptography (PQC). These are simply new cryptographic algorithms designed to withstand attacks from both classical and quantum computers. The U.S. National Institute of Standards and Technology (NIST) has been leading the charge to standardize these algorithms, and we’re finally seeing candidates in the final selection stages, giving vendors and companies a much-needed roadmap.

The real challenge here is achieving **cryptographic agility**. This is about a lot more than just swapping out one algorithm for another. It’s about building systems that can absorb new cryptographic standards without forcing a complete, and impossibly expensive, infrastructure overhaul. Just think about the sheer number of devices, apps, and protocols that depend on cryptography right now. A static, rigid approach is a guaranteed way to create vulnerabilities as quantum tech gets better. Security architectures must be designed for flexibility, allowing for smooth updates to new PQC algorithms as they get standardized and field-tested. This applies to everything from the secure boot process on a server and firmware updates on an IoT device to the VPN tunnels your remote workforce uses and data-at-rest encryption in the cloud. An organization’s ability to quickly push out new crypto primitives across its entire technology stack will be the deciding factor in its resilience against quantum attacks.

Fortinet’s PQC Integration Strategy

Fortinet is a cybersecurity giant, and they’ve gone on record with their commitment to integrate PQC across their product line, especially inside their FortiGate next-generation firewalls. Their game plan is a phased rollout that starts with the most critical communication channels first. We expect to see the first PQC-secured VPN tunnels go live by early 2027. This makes perfect sense as a starting point, since so much sensitive data flows through those connections and could be compromised long-term if they aren’t protected from future quantum decryption. Fortinet’s approach is to build the NIST-selected PQC algorithms, like CRYSTALS-Kyber for key exchange and CRYSTALS-Dilithium for digital signatures, directly into their FortiOS operating system. It will run in a “hybrid mode” at first, using both classical and PQC algorithms at the same time which creates a dual-layer protection that acts as a fallback while they collect real-world performance data on the new quantum-resistant crypto without dropping current security levels.

Fortinet’s roadmap doesn’t stop with VPNs. It extends PQC protection into other functions like secure boot mechanisms, firmware integrity validation, and eventually application-layer encryption. Given the huge number of Fortinet devices out there, this transition is a massive project. It’s going to take careful planning, a ton of testing, and working hand-in-glove with customers to get it adopted smoothly. Fortinet’s team knows that the performance overhead from PQC algorithms is a real worry, which is why a lot of their R&D is going into optimizing these algorithms to run on their custom ASIC hardware. That kind of hardware acceleration is going to be essential for minimizing the impact on network speed and latency. Nobody wants security that makes their network unusable. Their focus on cryptographic agility means that as new PQC standards are released or old ones get updated, Fortinet plans to push updates that let customers adapt without major disruptions.

Lumen’s Network-Level Quantum Readiness

Lumen Technologies has a different but equally important job in getting ready for the quantum future, because they own a gigantic global fiber network. Their work is about hardening the core network infrastructure itself against quantum attacks. Lumen’s threat intelligence group, Black Lotus Labs, is well-known for its research into new attack methods and is actively testing PQC solutions across the company’s network. This work covers securing their optical transport layers, their routing protocols, and all the internal systems they use to manage the network. A huge concern for a provider like Lumen is protecting its own operational data and keeping its network control plane secure. A compromised routing protocol or an insecure management system could cause a catastrophic failure affecting millions of customers.

Lumen’s strategy involves testing out different PQC implementations inside their network fabric, and they’re often working with universities and other tech companies to do it. They aren’t just sitting back and waiting for standards to be published. They’re contributing to our collective understanding of how PQC actually behaves in a high-throughput, real-world network. For example, their tests are measuring the latency impact of PQC key exchanges on network performance and figuring out the resource drain of these algorithms on routers and switches. The intelligence coming out of Black Lotus Labs gives everyone invaluable insight into how attackers might go after a quantum-enabled world, which lets Lumen build defenses before the attacks happen. It’s about identifying all the critical points of cryptographic dependency in their infrastructure and then prioritizing them for quantum-proofing. Lumen’s effort to secure the internet’s foundational layers with PQC shows how this has to be a collective effort.

Shared Goals and Collaborative Efforts

Fortinet and Lumen both get that no single company can secure the digital world from quantum threats on its own. Their goals go beyond their own products and into broader industry collaboration and standardization work. Both companies are active in the industry forums and working groups focused on PQC, including the ones run by NIST and other international bodies. This participation makes sure their product roadmaps are in sync with the global standards being hammered out, which helps prevent a fragmented market where nothing works with anything else. You’ve got Fortinet engineers contributing to discussions on PQC performance benchmarks while Lumen’s network architects provide insights on the headaches of deploying PQC at scale across complex networks. This collaboration is absolutely necessary because PQC is only effective if it’s adopted widely and implemented consistently across the whole stack, from endpoints to the cloud and the core network.

On top of that, both companies are putting money into education and awareness. They know the switch to PQC means big changes in how organizations manage keys and secure data. I’ve seen firsthand how important this vendor leadership is. They’re providing guidance to customers on how to audit their own quantum readiness, pinpoint the critical assets that need PQC first, and build a migration plan. Without clear direction from major tech providers, most enterprises would be completely lost trying to figure out this transition. Their combined efforts, whether through direct partnerships or just aligning through standards bodies, are creating a stronger, more resilient digital infrastructure for all of us. This is a foundational requirement for keeping trust and security in a world that’s only getting more connected.

The Path Forward: Preparing for the Quantum Era

Getting to a quantum-resistant world is a multi-year journey that needs strategic planning and the ability to adapt. Organizations can’t afford to wait until quantum computers are a common threat. The time to start getting ready is right now. The absolute first step is to conduct a complete inventory of every cryptographic asset you have. This means finding out where you use encryption, which algorithms are running, and (most importantly) the required lifespan of the data being protected. Any data with a long shelf life, think intellectual property, state secrets, or personal health information, is a prime target for “harvest now, decrypt later” attacks. Identifying these high-value targets is how you build a prioritized PQC migration plan.

Developing a quantum-readiness roadmap must also include a hard look at your current hardware and software to see if it has any cryptographic agility. Can your existing gear even support the new PQC algorithms with acceptable performance? What upgrades or architectural changes are you going to need? This usually means talking with vendors like Fortinet and Lumen to see their PQC roadmaps and figure out how their solutions will fit into your environment. Finally, investing in training your people is non-negotiable. Security teams need to get smart on the principles of PQC, the real-world implications of quantum attacks, and the new operational procedures for managing quantum-resistant systems. The transition will have its share of challenges, including potential performance hits and the complexity of running hybrid crypto environments for a while, but the long-term security payoff is well worth the short-term pain.

The work that Fortinet and Lumen are doing to develop and deploy PQC is essential for strengthening our digital defenses against the inevitable arrival of quantum computing. Their proactive strategies and collaborative work are paving the way for a more secure future, helping ensure that our critical data stays protected even as the entire field of cryptography changes.
