Bringing Identity Visibility & Zero Trust to Linux
Founded by identity and security experts, LinuxGuard delivers Linux-native visibility into who can do what, who did what, and where drift occurs—bringing practical least privilege to modern infrastructure.
Our Mission
LinuxGuard exists to give every organisation complete visibility into their Linux identity posture — every identity, every privilege, every connection, known, governed, and continuously assured.
Linux is the foundation of the modern enterprise. It deserves the same rigour applied to every other critical system.
Our Values
The principles that guide everything we do
Peter Cummings is the Founder & CEO of LinuxGuard, a cloud‑native platform built to solve a problem he has spent more than two decades fixing inside global enterprises: unmanaged Linux identity and privilege that quietly becomes a critical blind spot. He is the person organisations call when thousands of Linux servers underpin core services, but no one can clearly answer “who can do what, where, and why?”.
Starting his career compiling open‑source stacks on early Linux web servers (and learning the hard way what a single rm -rf / as root can do), Peter moved from building systems to securing them. He went on to lead identity, access, and infrastructure security programmes for highly regulated organisations across banking, payments, life sciences, energy, and government.
His most formative work came at Mastercard, where he redesigned Linux authentication and authorisation for a global payments infrastructure, and at Lonza, where he rebuilt a fragmented IAM function into a modern, automated, and audit‑ready platform. Similar roles at UBS, ING, SEB, BEC and others gave him a repeatable playbook for making Linux identity both visible and governable without slowing the business down.
LinuxGuard is the productised version of that playbook. It combines a lightweight agent, an opinionated “Zero Trust for Linux” model, and an identity graph engine that makes privilege relationships explicit instead of implicit. Customers can use it through a fixed‑scope 28‑day Fixed Fee Pilot that delivers audit‑ready evidence, or deploy the platform directly to keep Linux estates under continuous control—without locking themselves into a vendor monoculture.
Peter couples this practitioner background with formal training in machine learning, data‑driven decision‑making, and entrepreneurship, including postgraduate study in Machine Learning and AI, programmes at MIT, Oxford, and Wharton, and a track record as a startup CTO. He is an active voice in practitioner communities where identity, infrastructure, and automation meet, and brings a global perspective from hands‑on engagements across Europe, North America, and Africa.
