RSAC 2026 made one thing clear: networking and cybersecurity are no longer separate conversations. They’re becoming one operating model.
Beneath the AI headlines, the real shift was structural. Security is moving from alerting to action. Identity is becoming the control plane for everything, including users, workloads, and AI agents. And zero trust is finally turning into real infrastructure.
Together, these trends point to a deeper change. The network is no longer just where traffic flows. It’s where decisions get made. It’s where trust is enforced in real time.
Here are the three shifts that mattered most — and why they’re redefining how security and networking work together.
Fix it, Don’t Flag it
First, security is moving from detection to action. For years, security teams bought tools that found problems faster. That’s no longer enough. At RSAC 2026, the market signal was clear: finding issues is table stakes. The real value is fixing them.
Multiple conference analyses pointed to a shift away from point solutions toward platforms that integrate detection, response, and remediation. Security teams are also moving beyond using AI just to detect threats and toward automated remediation and policy enforcement.
At the same time, security operations are becoming increasingly automated, with workflows that include triage, investigation, isolation, and patching. That changes the role of the network. It becomes part of the response loop. The platforms that win will not just see what’s happening. They’ll help contain, route, isolate, and enforce in real time.
Identity Runs the Stack
The second trend at RSAC was identity. But not identity in the old sense. This is bigger than employee login or MFA. During this week’s show, the conversation expanded to workload identity, machine identity, and AI agent identity.
Biometric Update highlighted password-less authentication and controls for both human and non-human identities as a major conference theme. Vendors are designing systems that treat identities as dynamic and continuously verified, not static credentials. That shift reflects the reality that machines and agents now outnumber users and require the same level of trust enforcement.
SiliconANGLE added that ephemeral AI agents are breaking traditional identity models because they spin up, act, and disappear, often creating other agents along the way. These identities are short-lived and unpredictable, making static access controls ineffective. Security teams now need real-time visibility and control over identities that may only exist for seconds but still interact with critical systems.
This is where networking and security converge fast. Identity is quickly taking over as the central layer of control. If you cannot verify who or what is on the network at any moment, you cannot enforce trust with confidence.
Zero Trust Gets Real
Finally, zero trust showed up at RSAC 2026 in a more practical form. Coverage pointed to a shift away from static perimeters and toward policy models built around identity, context, and continuous verification. Security.com’s RSAC 2026 forecast reported identity has “cemented its status as the new perimeter” and argued that security teams now need a unified, policy-driven layer spanning IAM, PAM, and non-human identity management.
That’s a meaningful change. Trust can no longer hinge on where a user or workload sits on the network. It has to follow the connection, the workload, and the identity in real time. That’s as much a networking story as a security story, and it’s why networking can no longer sit outside the security model.
In conjunction with RSAC 2026, ZeroTier introduced ZeroTier Quantum, the world’s first end-to-end quantum-secure networking platform. This tackles another security trend — building for the quantum era. Purpose-built from the ground up, ZeroTier Quantum addresses the challenges of both an explosion of the attack surface and the realities of the quantum era by delivering end-to-end quantum-secure networking that integrates directly into existing platforms, infrastructure, and products.
It’s a natural extension of the same shift highlighted across RSAC 2026: security has to move closer to the connection, follow identity in real time, and be built directly into the network itself.
