RUNTIME SECURITY FOR AI AGENTS
See and stop what your AI agents actually do.
Others watch at the app layer. ZeroElement sits at the kernel, detecting escapes and misuse in real time inside the sandboxes and mobile endpoints you already run.

THE PROBLEM
Agents run real code. Nobody can see what they do.
Every company is shipping agents that execute code and take actions on real systems. Sandboxes isolate them, but isolation is a wall, not a window.
Blind at runtime
App-level logs and wrappers never see the syscalls, files, and network paths agents actually take.
Can't prove containment
No way to show an agent didn't break out or quietly exfiltrate a secret, on a server or a phone.
Security blocks the launch
With no kernel visibility, forensics, or control, security won't approve production.
The market already learned this the hard way. A CVSS 10.0 sandbox-escape CVE and the Google Antigravity escape both proved: when you can't see inside execution, application-level controls fail.
WHY NOW
2026: isolation got solved, and exposed the next problem.
- 01
Isolation commoditized
Firecracker microVMs are the baseline; every cloud ships a sandbox.
- 02
Escapes are real
CVSS 10.0 and the Antigravity escape proved isolation alone isn't enough. App-layer controls don't catch what happens below them.
- 03
Mobile is a critical vector
Agents and sensitive workloads land on phones and tablets. Mobile is a first-class endpoint, and most runtime security never reaches it.
THE GAP
The layer above isolation is unowned.
Solved & commoditizing

Unowned: our wedge
Kernel-deep runtime security
See · Detect · Enforce · Govern
Sandboxes answer "can it escape?" App-layer tools answer "what did the API see?" We answer "what is it doing at the kernel, is that bad, and stop it."
Most real harm never needs an escape. The box already holds the keys. And the box is increasingly a mobile device.
THE PLATFORM
EDR for AI agents.
ZeroElement is a kernel-deep, runtime-agnostic security layer that observes, detects, enforces, and governs across cloud sandboxes and mobile endpoints. Detection is a model trained on how agents behave, not hand-written app rules.
01
Observe
Kernel-deep flight recorder for every agent action: syscalls, files, network, process tree, across cloud sandboxes and mobile OS endpoints.
02
Detect
A behavioral model trained on how agents execute, flagging escapes, misuse, and covert channels in real time, below the app layer.
03
Enforce
Block, contain, or escalate on the edge, before secrets leave or host and device boundaries break.
04
Govern
Prove what happened for security, compliance, and incident response, without slowing the agent fleet.
THE INTELLIGENCE LAYER
A model trained on how agents behave, not humans.
Every behavioral model in security was trained on humans and servers. Agent execution is a new behavioral domain those models don't cover, and ZeroElement is the first trained on it.
New behavioral domain
Agent sessions look nothing like human operators or traditional servers. We model that domain from the ground up.
Edge + central
A small model decides privately on the endpoint; a larger fleet model learns and pushes improvements back down.
Fed by our own offense
Our red-team pipelines continuously generate agent escape and misuse scenarios that train the detector.
HOW IT WORKS
Kernel-deep. Runtime-agnostic. Fleet-smart.
Not app instrumentation. A kernel sensor on the endpoint for real-time, private decisions; a larger model that learns across the fleet and pushes improvements back down.

SAFETY BY DESIGN
Deep access, contained by construction.
Out-of-band by default
Observation and enforcement sit beside the agent path, not inside your application stack.
Contained by the VM
Deep sensors stay inside the isolation boundary you already trust.
Fail-open, always
If we can't decide safely, we never become the outage.
Human-gated actions
High-impact responses require explicit human approval.
We can never be the thing that takes production down.
WHY US
The one team that lives at both layers.
Kernel & endpoint internals
Ring-0 systems work where agents actually execute, not wrappers around their APIs.
Mobile endpoint expertise
iOS and Android internals as a first-class vector, because agents and secrets don't stay in the cloud.
Virtualization & hypervisor
Sandbox and microVM fluency from the isolation layer up.
Offensive security
Escape research that feeds detection, not just marketing slides.
Kernel depth plus mobile expertise is rare in one founding team, and exactly what this problem demands.
Alternative 01
Sandbox vendors
Own isolation. Don't own kernel-deep runtime security or agent behavioral detection.
Alternative 02
App-layer security
Watch APIs, prompts, and wrappers. Miss the syscalls and device paths where real harm happens, especially on mobile.
Our position
ZeroElement
Kernel-deep + cross-runtime: cloud sandboxes and mobile endpoints. The intersection no incumbent occupies.
EARLY ACCESS
Ship your agents to production, safely.
We're onboarding a small group of design partners. One workload, out-of-band, two weeks to first signal.
