Trevor Bestor · Security engineer
At Allegiant Air, I work on firewalls, security tooling, compliance, and incident response.
Before that I ran a software company. These days I’m building Rampart, an open-source policy layer for coding agents.
01
Rampart is an open-source policy layer for AI coding agents. It checks what an agent is trying to do before the action reaches your machine.
I built kid.gg to keep an eye on game servers without opening several different dashboards. It tracks status and player counts with custom probes for APIs that ordinary uptime checks cannot reach.

2025 - Present
Allegiant Air
I’m part of the team responsible for security across a large, multi-site environment, including the on-call work when something breaks.
2022 - 2025
Allegiant Air
I monitored and supported the network, handled escalations, and helped with incident response during a period of infrastructure change.
2020 - 2022
Linear, LLC
I started and ran a small software company. Our automation platform reached more than 1,800 users.
03
I’m a security engineer at Allegiant Air. Before that, I founded Linear, LLC and spent a few years building and running a software product.
I still build things outside of work. Rampart started because I wanted more control over what coding agents could do on my machine. kid.gg came from wanting one simple place to check the game servers I care about.
