Aembit vs semantic
Aembit is workload and agent identity, not a sandbox. Its Edge proxy intercepts outbound requests and injects short-lived, scoped credentials, so the workload never sees them. [1][2]
Access policies decide which workload reaches which service, combining user and agent identity, and each decision is logged. [2][3] Semantic pairs isolated execution with credentials on the host and file, Git and SSH permissions in one place.
| Aembitagent identity · not a sandbox | Semantic (smx)microVM + policy on your machines | |
|---|---|---|
| Isolation | Not applicable (not a sandbox) | One microVM per agent, own kernel |
| Where it runs | Aembit Cloud control plane; Edge in your environments [1] | Managed private beta; on-prem for enterprise (contact us) |
| Egress rules | Not applicable (access control per target) [1] | Security profiles enforced by host firewall; metadata and link-local always closed |
| Credentials kept out | Partial: short-lived credentials injected at the proxy [1] | Git tokens, SSH keys and model sign-ins stay on the host |
| File, Git, SSH permissions | Limited: service-level access policies [2] | Per path, repo, branch and SSH host; deny beats allow; enforced on the host |
| Tamper-evident agent log | Partial: access authorization events [3] | Hash-chained log of runs, events and refusals; read with smx agent logs |
| Snapshots, pause/resume | Not applicable | Snapshot, pause and resume with memory, disk and running processes |
| Local hosts (Linux / WSL2 / macOS) | Edge on Linux, Kubernetes, Windows; WSL2 and macOS — [4] | Linux (KVM) and Windows via WSL2; macOS planned |
| License | Commercial; open source — | Proprietary (private beta) |
Which one fits
When Aembit fits better
- You need agent and workload identity across AWS, Azure, GCP, Kubernetes and CI/CD. [4]
- You want credentials injected so agents never hold a secret, wherever they run. [2]
When Semantic fits better
- You need the sandbox too: a microVM per agent.
- Agents work on your repos and you need branch-level Git and per-path file permissions enforced outside the agent.
- You need a tamper-evident log of what the agent did inside the sandbox, including refusals.
Identity and sandbox together
Aembit governs which services an agent may reach and with which credentials. [2] Semantic governs the machine the agent runs on as well: its files, repos, branches, SSH hosts and egress, decided on the host.
Questions
Is Aembit a sandbox?
No, it is an identity and access layer. [1]
Can Aembit and Semantic be used together?
They cover different layers: Aembit for service access, Semantic for isolation and file, Git and SSH permissions.
