In the digital age, understanding the flow of data within organizations is more critical than ever. Especially when it comes to compliance with data protection laws like GDPR, knowing who handles your data and how is essential. Let's dive into an often overlooked yet vital part of data management: sub-processors. Understanding their role can help you navigate the complexities of data protection and ensure compliance.

Introduction to Sub-Processors

A sub-processor is a third-party service or vendor that a data processor employs to assist in handling personal data. Think of them as subcontractors in the world of data management. Under GDPR, they're an integral link in the data processing chain, helping primary processors provide their services.

Here's how it works: you have data controllers, processors, and sub-processors. The data controller is the entity that determines the purposes and means of processing personal data. They might use a processor to handle the data on their behalf. When this processor outsources part of their work to another company, that company becomes a sub-processor. This relationship is critical for a few reasons:

• Compliance: Both processors and sub-processors must adhere to GDPR guidelines, ensuring the protection of personal data.

• Transparency: Data controllers must know who is processing their data and for what purpose, including any sub-processors involved.

• Accountability: Processors are directly accountable to the controllers, and sub-processors, in turn, are accountable to the processors.

Understanding this chain of responsibility is crucial for maintaining the integrity and security of personal data. Whether you're a data controller or a processor, knowing your sub-processors and having clear agreements in place is a key step in GDPR compliance.

The role of Sub-Processors in Data Processing

Sub-processors play a crucial role in extending the capabilities of primary processors. They do so by taking on specific tasks, allowing primary processors to focus on their core functions. This delegation of tasks helps optimize overall data processing workflows.

For instance, cloud storage services like Amazon Web Services offer secure and scalable solutions for storing vast amounts of data. This is essential for companies that deal with big data and require reliable storage options without the need to manage physical servers.

Email marketing platforms, on the other hand, enable targeted communication with customers. They process personal data to segment audiences and personalize messages, enhancing customer engagement and conversion rates.

Customer relationship management (CRM) systems are another common service offered by sub-processors. They help businesses manage customer data, track interactions, and improve customer service. This is critical for maintaining strong customer relationships and driving sales.

In the context of Statsig, the use of sub-processors extends to areas like A/B testing, feature flagging, and product experimentation. Statsig integrates with various tools and services to enhance its platform, providing developers and product managers with robust testing and feature management capabilities. This integration allows for:

• Efficient feature rollouts: By leveraging sub-processors for feature flagging, you can gradually release new features, ensuring stability and user satisfaction.

• Data-driven decision-making: With A/B testing tools, you can test different variations of your product to see what works best, based on real user data.

• Scalable analytics: Sub-processors that specialize in data analytics can help you understand user behavior, making it easier to tailor your product to meet user needs.

By carefully selecting sub-processors, Statsig ensures that its platform remains efficient, secure, and compliant with data protection regulations like GDPR. This demonstrates the importance of sub-processors in not only extending services but also in maintaining high standards of data privacy and security.

Legal requirements and compliance

Under GDPR, using sub-processors comes with a set of legal implications. You need to have explicit consent from data controllers before you can use any sub-processors to handle personal data. This ensures that any third-party services you employ comply with GDPR standards and protect user data effectively.

One of the essential documents in this process is the Data Processing Agreement (DPA). This agreement outlines the responsibilities of both you and your sub-processors regarding data protection. For Statsig, this means ensuring that any sub-processors it employs for tasks like analytics or customer engagement have stringent data protection measures in place.

To legally appoint sub-processors, several conditions must be met:

• Written consent from data controllers.

• A DPA that includes obligations for data protection comparable to those in your agreement with the data controller.

• Transparency with data subjects about the use of sub-processors, including their roles and the data they process.

Statsig takes these requirements seriously. For instance, before engaging any sub-processors, Statsig provides a list of Authorized Sub-Processors to its customers. This list is available online and is updated regularly to maintain transparency. If Statsig decides to add a new sub-processor, it notifies customers in advance, giving them the chance to object based on data protection concerns.

Additionally, Statsig ensures that each sub-processor agrees to a DPA that imposes data protection obligations similar to those Statsig adheres to. This means that if a sub-processor fails in their data protection duties, Statsig remains accountable. This approach not only complies with GDPR but also builds trust with customers by demonstrating a commitment to data security.

Remember, choosing your sub-processors wisely is crucial. They need to be able to protect data as rigorously as you do. For Statsig, this means engaging services that understand the importance of data protection and are equipped to maintain the highest standards of privacy.

Importance of transparency in sub-processing

Transparency in disclosing sub-processors is not just a nice-to-have; it's a must under GDPR. You need to let your users know who is handling their data and for what purpose. This isn't just about compliance; it's about building trust with your users.

For example, at Statsig, we make our sub-processor list publicly available. This list includes details like the services provided and location of data processing. By doing this, we're not just ticking a box for GDPR compliance; we're also showing our commitment to data privacy and security.

Not being transparent about your sub-processors can lead to serious consequences. If you fail to disclose this information, you're not just risking fines under GDPR. You're also risking your reputation. Users today expect transparency, and failing to provide it can lead to distrust and loss of business.

Let's say you use third-party analytics or customer engagement tools. You need to tell your users about it. At Statsig, we integrate tools like Amplitude for analytics and Iterable for customer engagement. And we make sure you know about these integrations.

In short:

• Always disclose your sub-processors to your users.

• Make sure your DPA includes obligations for data protection.

• Remember, transparency builds trust, and trust is key to building a successful product.

Managing Sub-Processor Risks

When you use sub-processors, you're extending your trust chain. Risks include data breaches and non-compliance, which can lead to hefty fines and a tarnished reputation. Here's how to keep things tight:

Regular audits are your first line of defense. You should not only check that your sub-processors comply with data protection laws but also that they maintain high security standards. For instance, Statsig conducts regular reviews of our sub-processors, ensuring they meet our strict security criteria.

Data Processing Agreements (DPA) are non-negotiable. Your DPA should clearly outline the responsibilities of your sub-processors and include terms for data handling, confidentiality, and breach notifications. This formalizes the relationship and sets clear expectations.

Ensure encryption and access controls are in place. Your sub-processors should encrypt data both in transit and at rest. Access to data should be on a need-to-know basis, minimizing exposure.

Educate your team on the importance of vetting sub-processors. They should understand the potential risks and how to mitigate them. At Statsig, for example, we make sure our engineers and product managers are involved in the selection process, ensuring they're aware of the security and privacy implications.

Monitor continuously for new vulnerabilities. The digital landscape evolves rapidly, and what's secure today may not be tomorrow. Keeping an eye on your sub-processors' security practices ensures you can react quickly to any new threats.

In short:

• Conduct regular audits.

• Use detailed DPAs.

• Encrypt data and control access.

• Educate your team.

• Keep monitoring for vulnerabilities.

By following these practices, you can minimize risks and maintain trust in your service.
