Cisco Catalyst Center vs Sandlock

Cisco Catalyst Center has no write-up on Specifiction yet; its figures are above.

Sandlock is a Linux process sandbox for confining untrusted code with policies enforced by the kernel. It uses Landlock, seccomp-bpf, and seccomp user notification to control filesystem access, network activity, system calls, and resource use. Policies can deny network egress by default, apply HTTP method, host, and path rules, stage writes through copy-on-write, and set resource limits. A supervisor can attach credentials through a proxy after an HTTP access check, keeping the secret value out of the sandboxed workload. Interfaces include a CLI, Python SDK, Rust API, Go SDK, OCI runtime, and MCP server. The OCI runtime works with containerd, CRI-O, and Kubernetes, while the remote MCP API can connect to Claude Desktop, Cursor, or another MCP client. Sandlock runs as an ordinary user without root, a container runtime, or a hypervisor. Linux 6.12 or later supports the full protection set by default; older kernels require explicit waivers for missing protections. It shares the host kernel, excluding kernel vulnerabilities and hardware side channels from its guarantees.
