The introduction, standardization, and deployment of 5G have enabled faster speeds, lower latency, and more reliable connectivity across industries. As innovation in mobile networks continues, 6G is poised to extend these capabilities even further. While 6G is often framed as a radical leap forward, the reality is today’s 5G deployments are already laying much of the security foundation on which 6G will depend, making continuity the real challenge at hand.
Enterprises that treat 6G as a future problem risk repeating early 5G security mistakes, especially around device identity, lifecycle management, and trust in increasingly autonomous networks. To ensure the transition from 5G to 6G is built on trust and transparency, security leaders must separate vision from reality and identify the security throughlines that will protect networks, devices, and decision-making systems alike.
What’s Hype vs What’s Real with 6G: Lessons from 5G Maturity
6G is poised to transform AI-driven network optimization, ultra-low latency, and pervasive sensing, among other advancements. However, these can only be achieved if trust, automation, and governance established by 5G are effectively operationalized. As it stands, 5G networks continue to struggle with uneven adoption, operational complexity, and security models that are still catching up to scale.
Despite excitement around the future of connectivity, designing a new-generation mobile network is still largely complicated, with commercial deployment still several years away. Standards for 6G have yet to be finalized, requiring coordination among researchers, industry players, and standards bodies before networks can be widely deployed.
Today’s challenges with 5G won’t disappear with 6G; they’ll only be amplified. Without addressing existing gaps, 6G risks becoming less a breakthrough and more a delayed initiative.
Why Lifecycle Management and Credentialing Are the Throughline from 5G to 6G
Device identity, lifecycle management, and access control are critical in the transition from 5G to 6G. The exponential growth of connected objects over the past decade has exposed the limits of static provisioning and one-time credentialing.
As a result, secure device onboarding, continuous credential management, and proper decommissioning are essential to 6G’s success. These practices ensure devices remain properly managed from the get-go, preventing unauthorized access by malicious actors. With devices increasingly operating autonomously and at massive scale, establishing transparency at every stage of the lifecycle is critical.
In 6G, unmanaged identities do more than create risk, as they become attack surfaces themselves. Lifecycle-driven security is key to mitigating risks and maintaining trust as networks evolve toward 6G.
From Today’s Fraud to Tomorrow’s Algorithmic Risk
While securing devices is a critical part of protecting the transition to 6G, risks extend beyond devices to network behavior as well. Today’s fraud patterns of API abuse, automated attacks, and identity exploitations translate directly into future risks for self-optimizing, AI-assisted networks.
As networks gain decision-making authority, attacks will increasingly focus on logic, models, and trust assumptions rather than infrastructure alone. We see this today with attackers focusing on APIs, as APIs represent only ~14% of attack surfaces, yet attract 44% of advanced bot traffic. As the control plane of digital services, APIs are already facing a disproportionate share of sophisticated automated attacks, signaling increased risk for tomorrow’s highly autonomous networks.
The playbook for protecting against today’s fraud and abuse can be translated into protection for future 6G algorithmic risk. Cryptographic agility, verifiable identities, and policy enforcement that adapts as quickly as the network itself will be essential.Similar to the way today’s devices are defended, securing 6G requires protecting decision-making in addition to connectivity.
Using 5G as a Foundation for 6G Security
6G presents an exciting leap forward for the next era of mobile communication. Enterprises don’t need to wait for 6G standards to act, the essential security building blocks are already clear.
Strong identity foundations, lifecycle security, and resilience against automated abuse are table stakes for both 5G and 6G. The organizations that thrive in the 6G era are already treating 5G as a rehearsal for autonomy at scale, laying the groundwork for successful 6G deployments as infrastructure and standards mature.
