Security and Privacy Design

This document serves as the relevant Annex to the Terms of Service, the Privacy Policy and the Data Processing Addendum, when applicable. It provides more information regarding Netdata’s technical and organizational security and privacy measures.

We have given special attention to all aspects of Netdata, ensuring that everything throughout its operation is as secure as possible. Netdata has been designed with security in mind.

Netdata's Security Principles

Security by Design

Netdata, an open-source software widely installed across the globe, prioritizes security by design, showcasing our commitment to safeguarding user data. The entire structure and internal architecture of the software is built to ensure maximum security. We aim to provide a secure environment from the ground up, rather than as an afterthought.

Netdata Cloud ensures a secure, user-centric environment for monitoring and troubleshooting, treating observability data and observability metadata distinctly to maintain user control over system insights and personal information. Observability data, which includes metric values (time series) and log events, remains fully under user control, stored locally on the user's premises. Observability metadata, including hostnames, metric names, alert names, and alert transitions, is minimally required by Netdata Cloud and securely managed for routing and platform usage purposes.

Compliance with Open Source Security Foundation Best Practices

Netdata is committed to adhering to the best practices laid out by the Open Source Security Foundation (OSSF). Currently, the Netdata Agent follows the OSSF best practices at the passing level. Feel free to audit our approach to the OSSF guidelines

Netdata Cloud boasts of comprehensive end-to-end automated testing, encompassing the UI, back-end, and Agents, where involved. In addition, the Netdata Agent uses an array of third-party services for static code analysis, security analysis, and CI/CD integrations to ensure code quality on a per pull request basis. Tools like Github's CodeQL, Github's Dependabot, our own unit tests, various types of linters, and Coverity are utilized to this end.

Moreover, each PR requires two code reviews from our senior engineers before being merged. We also maintain two high-performance environments (a production-like kubernetes cluster and a highly demanding stress lab) for stress-testing our entire solution. This robust pipeline ensures the delivery of high-quality software consistently.

Regular Third-Party Testing and Isolation

While Netdata doesn't have a dedicated internal security team, the open-source Netdata Agent undergoes regular testing by third parties. Any security reports received are addressed immediately. In contrast, Netdata Cloud operates in a fully automated and isolated environment with Infrastructure as Code (IaC), ensuring no direct access to production applications. Monitoring and reporting is also fully automated.

Security Vulnerability Response

Netdata has a transparent and structured process for handling security vulnerabilities. We appreciate and value the contributions of security researchers and users who report vulnerabilities to us. All reports are thoroughly investigated, and any identified vulnerabilities trigger a Security Release Process.

We aim to fully disclose any bugs as soon as a user mitigation is available, typically within a week of the report. In case of security fixes, we promptly release a new version of the software. Users can subscribe to our releases on GitHub to stay updated about all security incidents. More details about our vulnerability response process can be found here.

Adherence to Open Source Security Foundation Best Practices

In line with our commitment to security, we uphold the best practices as outlined by the Open Source Security Foundation. This commitment reflects in every aspect of our operations, from the design phase to the release process, ensuring the delivery of a secure and reliable product to our users.

Compliance with Regulations

Netdata is committed to ensuring the security, privacy, and integrity of user data. It complies with both the General Data Protection Regulation (GDPR), a regulation in EU law on data protection and privacy, and the California Consumer Privacy Act (CCPA), a state statute intended to enhance privacy rights and consumer protection for residents of California.

Compliance with GDPR and CCPA

Compliance with GDPR and CCPA are self-assessment processes, and Netdata has undertaken thorough internal audits and controls to ensure it meets all requirements.

As per request basis, any customer may enter with Netdata into a data processing addendum (DPA) governing customer’s ability to load and permit Netdata to process any personal data or information regulated under applicable data protection laws, including the GDPR and CCPA.

Data Transfers

While Netdata Agent itself does not engage in any cross-border data transfers, certain observability metadata (e.g. hostnames, metric names, alert names, and alert transitions) is transferred to Netdata Cloud solely to provide routing and alert notifications. Observability data, consisting of metric values (time series) and log events, stays strictly within the user's infrastructure, mitigating cross-border data transfer concerns.

For users leveraging Netdata Cloud, observability data is securely tunneled through Netdata Cloud for real-time viewing, similar to a VPN, without being stored on Netdata Cloud servers. This approach ensures that Netdata Cloud maintains only necessary metadata, while full control of observability data remains with the user.

Netdata Cloud only stores Netdata Cloud users identification data (such as observability users' email addresses) and infrastructure metadata (such as infrastructure hostnames) necessary for Netdata Cloud's operation. All these metadata are stored in data centers in the United States, using compliant infrastructure providers such as Google Cloud and Amazon Web Services. These transfers and storage are carried out in full compliance with applicable data protection laws, including GDPR and CCPA.

Privacy Rights

Netdata ensures user privacy rights as mandated by the GDPR and CCPA. This includes the right to access, correct, and delete personal data. These functions are all available online via the Netdata Cloud User Interface (UI). In case a user wants to remove all personal information (email and activities), they can delete their Netdata Cloud account by logging into https://app.netdata.cloud and accessing their profile, at the bottom left of the screen.

Regular Review and Updates

Netdata is dedicated to keeping its practices up-to-date with the latest developments in data protection regulations. Therefore, as soon as updates or changes are made to these regulations, Netdata reviews and updates its policies and practices accordingly to ensure continual compliance.

While Netdata is confident in its compliance with GDPR and CCPA, users are encouraged to review Netdata's privacy policy and reach out with any questions or concerns they may have about data protection and privacy.

Anonymous Statistics

The anonymous statistics collected by the Netdata Agent pertain to installations rather than individual users, capturing general information such as community size, plugin types, crashes, operating systems, and feature usage. Importantly, observability data — metric values and log events — remain local to the user's infrastructure and are not collected in this process. Observability metadata, including unique IDs for installations, is anonymized and stored solely to support product development and community understanding.

Netdata also collects anonymous telemetry events, which provide information on the usage of various features, errors, and performance metrics. This data is used to understand how the software is being used and to identify areas for improvement.

The purpose of collecting these statistics and telemetry data is to guide the development of the open-source Agent, focusing on areas that are most beneficial to users.

Users have the option to opt out of this data collection during the installation of the Agent, or at any time by removing a specific file from their system.

Netdata retains this data indefinitely in order to track changes and trends within the community over time.

Netdata does not share these anonymous statistics or telemetry data with any third parties.

By collecting this data, Netdata is able to continuously improve their service and identify any issues or areas for improvement, while respecting user privacy and maintaining transparency.

Internal Security Measures

Internal Security Measures at Netdata are designed with an emphasis on data privacy and protection. The measures include:

1. Observability data and metadata distinction Netdata Cloud securely handles observability metadata in isolated environments, while observability data remains exclusively within user premises, stored locally and managed by the user. This distinction ensures that only minimal metadata is required for routing and system identification.
2. Infrastructure as Code (IaC) : Netdata Cloud follows the IaC model, which means it is a microservices environment that is completely isolated. All changes are managed through Terraform, an open-source IaC software tool that provides a consistent CLI workflow for managing cloud services.
3. TLS Termination and IAM Service : At the edge of Netdata Cloud, there is a TLS termination, which provides the decryption point for incoming TLS connections. Additionally, an Identity Access Management (IAM) service validates JWT tokens included in request cookies or denies access to them.
4. Session Identification : Once inside the microservices environment, all requests are associated with session IDs that identify the user making the request. This approach provides additional layers of security and traceability.
5. Data Storage : Data is stored in various NoSQL and SQL databases and message brokers. The entire environment is fully isolated, providing a secure space for data management.
6. Authentication : Netdata Cloud does not store credentials. It offers three types of authentication: GitHub Single Sign-On (SSO), Google SSO, and email validation.
7. DDoS Protection : Netdata Cloud has multiple protection mechanisms against Distributed Denial of Service (DDoS) attacks, including rate-limiting and automated blacklisting.
8. Security-Focused Development Process : To ensure a secure environment, Netdata employs a security-focused development process. This includes the use of static code analyzers to identify potential security vulnerabilities in the codebase.
9. High Security Standards : Netdata Cloud maintains high security standards and can provide additional customization on a per contract basis.
10. Employee Security Practices : Netdata ensures its employees follow security best practices, including role-based access, periodic access review, and multi-factor authentication. This helps to minimize the risk of unauthorized access to sensitive data.
11. Experienced Developers : Netdata hires senior developers with vast experience in security-related matters. It enforces two code reviews for every Pull Request (PR), ensuring that any potential issues are identified and addressed promptly.
12. DevOps Methodologies : Netdata's DevOps methodologies use the highest standards in access control in all places, utilizing the best practices available.
13. Risk-Based Security Program : Netdata has a risk-based security program that continually assesses and mitigates risks associated with data security. This program helps maintain a secure environment for user data.

These security measures ensure that Netdata Cloud is a secure environment for users to monitor and troubleshoot their systems. The company remains committed to continuously improving its security practices to safeguard user data effectively.

PCI DSS

PCI DSS (Payment Card Industry Data Security Standard) is a set of security standards designed to ensure that all companies that accept, process, store or transmit credit card information maintain a secure environment.

Netdata is committed to providing secure and privacy-respecting services, and it aligns its practices with many of the key principles of the PCI DSS. However, it's important to clarify that Netdata is not officially certified as PCI DSS-compliant. While Netdata follows practices that align with PCI DSS's key principles, the company itself has not undergone the formal certification process for PCI DSS compliance.

PCI DSS compliance is not just about the technical controls but also involves a range of administrative and procedural safeguards that go beyond the scope of Netdata's services. These include, among other things, maintaining a secure network, implementing strong access control measures, regularly monitoring and testing networks, and maintaining an information security policy.

Therefore, while Netdata can support entities with their data security needs in relation to PCI DSS, it is ultimately the responsibility of the entity to ensure full PCI DSS compliance across all of their operations. Entities should always consult with a legal expert or a PCI DSS compliance consultant to ensure that their use of any product, including Netdata, aligns with PCI DSS regulations.

HIPAA

HIPAA stands for the Health Insurance Portability and Accountability Act, which is a United States federal law enacted in 1996. HIPAA is primarily focused on protecting the privacy and security of individuals' health information.

Netdata is committed to providing secure and privacy-respecting services, and it aligns its practices with many key principles of HIPAA. However, it's important to clarify that Netdata is not officially certified as HIPAA-compliant. While Netdata follows practices that align with HIPAA's key principles, the company itself has not undergone the formal certification process for HIPAA compliance.

HIPAA compliance is not just about technical controls but also involves a range of administrative and procedural safeguards that go beyond the scope of Netdata's services. These include, among other things, employee training, physical security, and contingency planning.

Therefore, while Netdata can support HIPAA-regulated entities with their data security needs and is prepared to sign a Business Associate Agreement (BAA), it is ultimately the responsibility of the healthcare entity to ensure full HIPAA compliance across all of their operations. Entities should always consult with a legal expert or a HIPAA compliance consultant to ensure that their use of any product, including Netdata, aligns with HIPAA regulations.

SOC 2 Compliance
