pyseccomp
An interface to libseccomp using ctypes. API compatible with libseccomp's Python bindings.
Decision gist · record as of 2026-08-14
No, unless you have a specific reason to need this package. The package is abandoned, untested on modern Python versions, and offers no advantage over maintained alternatives. Use it only as a last-resort fallback when other options cannot be installed.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires libseccomp library to be installed on the system; pyseccomp is a ctypes wrapper and does not bundle it.
- Low install friction—pure Python, no compiled dependencies.
- However, the package is abandoned; the last commit was 2021-06-12 and no releases since 2021-01-02.

Alternatives
Verify before relying
pip install pyseccomp
import pyseccomp- Whether pyseccomp remains compatible with current libseccomp library versions and modern Linux kernels.
- Whether the ctypes-based implementation has performance or correctness gaps compared to alternatives.
- Whether Python 3.9+ is supported despite classifiers only listing 3.6–3.8.
- Whether libseccomp must be pre-installed on the system for pyseccomp to function.
What it is and what it does
pyseccomp is a pure-Python ctypes wrapper around libseccomp, the Linux system call filtering library. It allows you to programmatically define seccomp policies—rules that restrict which system calls a process may invoke. The package is designed as an alternative when native bindings are unavailable, and is API compatible with libseccomp's own Python bindings.
The package has been abandoned since early 2021 and receives no maintenance. It targets Python 3.6, 3.7, and 3.8, and depends only on the system libseccomp library, making installation frictionless. However, its age means compatibility with modern Python versions and current libseccomp APIs is unverified.
Use it for
- Sandboxing untrusted code by restricting system calls available to a subprocess.
- Building container or isolation tools that need seccomp policy configuration.
- Providing an alternative seccomp interface when other options are unavailable.
- Testing or prototyping seccomp policies in pure-Python environments.
