Identify & Resolve Security Vulnerabilities Faster
Shorten the lengthy remediation process of investigating, rebuilding, retesting and updating runtime environments. The ActiveState Platform lets you find, fix and automatically rebuild a secure version of your Python, Perl and Tcl environments in minutes, decreasing Mean Time To Remediation (MTTR) from days to hours.

Python 3.9 – Beta
We’re introducing a whole new way to work with Python from ActiveState. Rather than a monolithic ActivePython distribution, our Python 3.9 release lets you:
- Manage packages with a single toolchain for both Windows and Linux -- reduce tool maintenance overhead
- Deploy into a virtual environment by default (simpler than venv) -- run multiple versions of Python without dependency conflicts
- Automatically build dependencies from source in parallel, including linked C libraries -- faster, more secure Python builds

Unlike ActivePython, our Python 3.9 provides:
- A much smaller footprint -- just the language and the packages you need to get started
- Standard licensing -- all the packages you install have just their original licensing
- Command line installation -- automated installation with a single line of code
Ready to try it out?
- Build your own version (select “Python” -> “Custom Python Build” -> version 3.9.2), or
- Download just the language and our State Tool CLI and go from there.
- To get started with State Tool, check out our cheat sheet, which shows you how to search/install/remove packages, and otherwise manage your environment.

CLI-Enabled Security/CVE Reports – Beta
View the number and severity of vulnerabilities in your Python or Perl projects at a glance, or access a detailed report using the State Tool by running state cve.

Project Branching

Role-Based Access Control (RBAC)
You can now add users to your organization on the ActiveState Platform and assign them a role:
- Read Only - user can only install and work with your runtime environments
- Editor - user can edit existing runtime environments, as well as create new ones
- Admin - user can edit and create runtime environments, as well as invite others to your organization

In this way you can provide greater control over how your users interact with your runtime environments. For example, you may want your lead developer to be the only person to be able to create and modify the runtime environment used by their team.
Python 2.7.18.3 Now Available
A critical security vulnerability (CVE-2021-3177) that allows for buffer overrun exploits, such as denial of service or the running of malicious code, affects Python 2. As such, we have released a fix for Python 2 as part of our Python 2 End of Life extended support. We have also made the source code available for security experts and open source maintainers to review and incorporate into their projects.
Perl 5.32.1 Now Available
Security/CVE Reports via API
- Number and severity level of all vulnerabilities in your environment
- Group dependencies by level of vulnerability
The simplest way to check your environment for vulnerabilities is by using our interactive documentation. See how to view vulnerabilities with our Platform.
