MemGuard, explained for beginners

MemGuard screens what an AI agent stores in memory: known attacks are blocked, and anything that might instruct the agent waits for a person.

No AI background needed. Read this page (3 minutes), then try the five live demo tools, then the copy, paste, send page and the six-page seller's guide.

What it is

Agents with memory carry notes between sessions. An attacker can plant a note today that steers the agent next month.

MemGuard scans each memory before it is stored. It deliberately errs on the side of asking a person, so it holds some ordinary notes too.

An everyday comparison

A mail room for an agent's diary: known scams are shredded, and anything that reads like an order goes to a manager.

How it works, in 3 steps

  1. The agent wants to save a memory.
  2. MemGuard scans it.
  3. Known attack: BLOCK. Might instruct the agent: HOLD_FOR_REVIEW. Otherwise: ALLOW.
