AI SECURITY SIDECAR

Aegis

Point your agent at Aegis. Unsafe tool calls return HTTP 403 before they execute. On an Aegis Node, the same intent is enforced at the syscall.

+0.78msmedian overhead
HTTP 403deny before the origin
Air-gapno phone-home

Measured by an independent external tester in a home lab: 40 calls through the userspace sidecar vs. direct, median 1.18 ms vs 0.40 ms.

Classifiers score text. Aegis binds the tool call.

A Rust data plane sits in-line with LLM traffic. A Python control plane owns policy, Crucible, and compliance — never the hot path. Laptop eval proves userspace 403. Kernel EPERM is Ubuntu 24.04 only — not Docker Desktop.

Sidecar 403

Allowlist, RBAC, sequence, intent, signatures, HITL, and flow/taint. Deny is HTTP 403 — the request is never forwarded.

Attach wrapper

attach.bat / attach.sh launches the existing process. Vendor keys stay with you. No SDK rewrite for supported clients.

Signed evidence

Ed25519 decision records you can export. Not a marketing score.

Kernel EPERM

On Aegis Node, an LSM grant ticket refuses open / exec / connect outside what the tool call declared.

Flow / taint

PCI, PII, and secret-shaped reads cannot sink via HTTP, email, or shell.

Command Deck

Protect the agent, fire a canary, copy the last 20 signed decisions. Forge and SOC stay in the command palette.

✓ Independent review: sidecar bypass vs kernelUserspace 403 on any hostEPERM on Ubuntu 24.04 Node
“My sharpest finding on the sidecar was the bypass: raw urllib returned 200 and hit the sink because it did not go through a patched SDK constructor. At the kernel that argument disappears — the deny is at the syscall, so the language, the library, a subprocess or a compiled binary are all irrelevant.”

Two proofs. Do not mix them.

Laptop (any OS)

  • OpenAI-compatible, Anthropic, or Gemini SDK pointed at the sidecar
  • attach wrapper — prompts stay on your network
  • Docker Desktop for HTTP 403s
  • Signed decision export after the in-Deck canary

Aegis Node (Linux)

  • Ubuntu 24.04 VM for kernel EPERM — not Docker Desktop WSL
  • Stops urllib / subprocess / compiled binaries that skip the proxy
  • Not FedRAMP / ATO / FIPS 140 / HA multi-region
  • Not a classifier — it binds the tool call, not a content score

First HTTP 403 without rewriting the agent.

01

Download & start

Same zip for every plan. No account required to run.

# Windows
AEGIS Suite.bat

# macOS / Linux
./start.sh
02

Attach the existing process

The wrapper keeps your vendor key and sets OPENAI_BASE_URL. Constructor snippets are a fallback if the SDK ignores env.

Windows:     attach.bat support-bot -- python your_agent.py
macOS/Linux: ./attach.sh support-bot -- python your_agent.py
03

Fire the canary in Command Deck

Protect → Fire canary. You should see HTTP 403 (paid/trial) or WOULD_BLOCK (audit) and a signed row you can copy.

04

Kernel proof (optional)

Ubuntu 24.04 only. Multipass, a cloud image, or book the 48-hour containment audit if you are on Windows.

./appliance/multipass-launch.sh
# or
./start-node.sh

Three plans. Same zip. 14-day trial on every tier.

Builder, Standard, and Enterprise match the Stripe catalog and the Standard SKU zip (aegis-standard.zip). Cloud-commit buyers use a marketplace private offer (floor $25k) — that is not self-serve checkout.
