Trust and Security
Streamlit is a framework that turns Python scripts into interactive apps, giving data scientists the ability to quickly create data and model-based apps for the entire company.
A simple Streamlit app is:
import streamlit as st number = st.slider("Pick a number: ", min_value=1, max_value=10) st.text("Your number is " + str(number))
When you streamlit run
my_app.py, you start a web server that runs the interactive application on your local computer at http://localhost:8501. This is great for local development. When you want to share with your colleagues, Streamlit Cloud enables you to deploy and run these applications in the cloud. Streamlit Cloud handles all the details of scaling, reliability, and security as well as providing you an interface for easily managing your deployed apps.
This document is an overview of how we provide best-in-industry security for you. We'll cover all the important areas in the lifecycle of your data:
- Product Security: how we ensure only you can create and view apps that access your data
- Network and Application Security: how we ensure your data is protected when it is in our cloud
- Ongoing Operations: how we stay good stewards of security best practices
All access and sign-ins to Streamlit are conducted via an SSO provider: GitHub, GSuite, and many other platforms are supported. We can work with your IT team to integrate to your provider of choice. We do not store customer passwords.
We encrypt sensitive customer data (e.g. secrets, authentication tokens) at-rest with AES256 as described in Google's documentation.
Permissions and Role-Based Access Control
Our permission levels inherit from the permissions you have assigned in GitHub. Users with write access to a GitHub repository for a given app will be able to make changes in the Streamlit administrative console. Only users with admin access to a repository are able to deploy and delete apps.
Network and Application Security
Our physical infrastructure is hosted and managed within Google Cloud Platform (GCP) using their secure data centers. Streamlit leverages many of the platform's built-in security, privacy, and redundancy features. GCP continually monitors its data centers for risk and undergoes assessments to ensure compliance with industry standards. GCP's data centers have numerous accreditations, including ISO-27001, SOC 1 and SOC 2.
Virtual Private Cloud
All of our servers are within a virtual private cloud (VPC) with firewalls and network access control lists (ACLs) to allow external access to a select few API endpoints; all other internal services are only accessible within the VPC.
All Streamlit apps are served entirely over HTTPS. All data sent to or from Streamlit over the public internet is encrypted in transit using 256-bit encryption. Our API and application endpoints are TLS only (v1.2). We use only strong cipher suites and HTTP Secure Transport Security (HSTS) to ensure browsers interact with Streamlit apps over HTTPS. We also encrypt data at rest using AES-256.
Permissions and Authentication
Access to customer data is limited to authorized employees who require it for their job. We run a zero-trust corporate network so there are no corporate resources or additional privileges gained from being on Streamlit's internal network. We utilize single sign-on, 2-factor authentication (2FA), and enforce strong password policies to ensure access to all cloud-related services are protected.
We have an internal protocol for handling security events which includes escalation procedures, rapid mitigation, and documented post-mortems. We notify customers promptly and publicize security advisories at https://streamlit.io/advisories.
Streamlit uses third-party security tools to scan for vulnerabilities on a regular basis. Our security partners conduct periodic, intensive penetration tests on the Streamlit platform. Our product development team immediately responds to any identified issues or potential vulnerabilities to ensure the quality and security of Streamlit applications.
Security and Compliance Programs
SOC 2 Type 1
We're committed to meeting industry security standards and are SOC2 readiness certified.
All Streamlit employees go through a thorough background check before hiring.
We take a least-privilege approach to the access and handling of data. While we retain a minimal amount of customer data and limit internal access on a need-to-know basis, all employees are required to review related security policies and are trained on proper data handling to ensure they uphold our strict commitment to the privacy and security of your data.
All employees sign a confidentiality agreement before they start at Streamlit.
We keep our systems up-to-date with the latest security patches and continuously monitor for new vulnerabilities through compliance and security mailing lists. This includes automatic scanning of our code repositories for vulnerable dependencies.
