+### Seccomp Profiles
+
+FetchML includes a hardened seccomp profile for container sandboxing at `configs/seccomp/default-hardened.json`.
+
+**Features:**
+- **Default-deny policy**: `SCMP_ACT_ERRNO` blocks all syscalls by default
+- **Allowlist approach**: Only explicitly permitted syscalls are allowed
+- **Multi-architecture support**: x86_64, x86, aarch64
+- **Blocked dangerous syscalls**: ptrace, mount, umount2, reboot, kexec_load, open_by_handle_at, perf_event_open
+
+**Usage with Docker/Podman:**
+
+```bash
+# Docker with seccomp
+docker run --security-opt seccomp=configs/seccomp/default-hardened.json \
+  -v /data:/data:ro \
+  my-image:latest
+
+# Podman with seccomp
+podman run --security-opt seccomp=configs/seccomp/default-hardened.json \
+  --read-only \
+  --no-new-privileges \
+  my-image:latest
 ```

-### Docker Worker
-**File:** `configs/workers/docker.yaml`
+**Key Allowed Syscalls:**
+- File operations: `open`, `openat`, `read`, `write`, `close`
+- Memory: `mmap`, `munmap`, `mprotect`, `brk`
+- Process: `clone`, `fork`, `execve`, `exit`, `wait4`
+- Network: `socket`, `bind`, `listen`, `accept`, `connect`, `sendto`, `recvfrom`
+- Signals: `rt_sigaction`, `rt_sigprocmask`, `kill`, `tkill`
+- Time: `clock_gettime`, `gettimeofday`, `nanosleep`
+- I/O: `epoll_create`, `epoll_ctl`, `epoll_wait`, `poll`, `select`
