Perimeterless LLC is Tyler Webb's consulting practice — built around zero trust across identity, network, and data, and the broader security engineering that surrounds it.
I'm a cybersecurity consultant based in Kennesaw, Georgia, specializing in zero trust architecture — identity and access, ZTNA and SASE, and the network and cybersecurity engineering that surrounds them. I founded Perimeterless LLC to work directly inside client environments — hands-on, console-first — rather than at a distance from the systems I'm designing.
The name is a statement about the work: the network perimeter most security programs are still built around stopped mapping to reality years ago. Applications live across clouds you don't control, users connect from networks you don't manage, and the old model of a defended boundary doesn't hold. The practice exists to build what replaces it — identity-based, continuously verified access, from IdP and SSO through privileged access management to the network and data layers — without being tied to any one vendor's version of that idea.
My approach is deliberately hands-on: direct configuration and policy work, discovery that starts in the live environment rather than in a stakeholder interview, and architecture that's validated against real traffic before it's called done. That approach carries across every layer — identity, network, cloud, and endpoint — because zero trust only works when the layers around it hold up too.
Live configuration review comes first. Interviews inform priorities, they don't replace looking at what's actually deployed.
Architecture decisions start from your environment and requirements, not from a single platform's feature set.
Every change is compared against a documented baseline, so tuning decisions are auditable, not anecdotal.
