How Similarweb Automated DSRs to Scale Global Privacy Compliance with MineOS

Overview

Similarweb helps businesses understand what’s happening online by measuring web and app traffic and turning it into actionable insights through its SaaS analytics platform. As the company expanded - adding new products and integrating acquired businesses - DSR volumes rose and data became more fragmented across systems. MineOS gives Similarweb a scalable path from manual, ticket-based handling to controlled DSR automation with the auditability needed for GDPR compliance.

The Challenge

Similarweb was handling DSRs through largely manual processes supported by a basic ticketing system. As request volumes increased, this approach became unsustainable, creating operational bottlenecks and heavy reliance on internal teams.

Key challenges included:

• A highly distributed data environment spanning across cloud, databases, CRMs and products from acquired companies still operating independently.
• A need to implement complete and accurate data deletion without unintended removal of data where retention is required.
• A need to strengthen  auditing, reporting, and proof of compliance processes, an essential requirement for a public company.

Why Similarweb Chose MineOS

Similarweb required a true automation solution for DSRs - one that went far beyond ticket management. MineOS stood out by offering:

• End-to-end DSR automation with strong governance, auditing, and reporting capabilities.
• Fine-grained control over read and write permissions, enabling automation while preserving manual approvals and exception handling.
• Flexible integration capabilities across complex and custom-built systems, including proprietary AWS environments.
• The ability to test safely in sandbox environments and roll out automation in phases.
• A scalable platform aligned with Similarweb’s growth trajectory and regulatory obligations.
  

Solution & Implementation

Similarweb began with a structured internal assessment, mapping systems and defining clear requirements for DSR automation. This process involved stakeholders from security, IT, privacy, and legal teams.

Implementation followed a phased approach:

• Security & Architecture Review: A comprehensive security review was conducted with Mine’s security team and architect, culminating in approval (“green light”) from Similarweb’s security leadership.
• Proof of Concept (POC): Similarweb initiated a POC focused on Salesforce, testing MineOS in a sandbox environment to validate automation flows, access controls, and data accuracy.
• Phased Rollout: Following successful testing, internal alignment, and legal review, Similarweb began building a roadmap for expanding DSR automation to additional systems and data sources.

Throughout the process, Mine worked closely with Similarweb’s teams to ensure flexibility, transparency, and confidence at every stage of deployment.

The Result:
Faster, Auditable DSR Operations

By implementing MineOS, Similarweb transitioned from manual, ticket-based DSR handling to controlled automation with full visibility and accountability:

• ~80% Reduction in Manual Effort: Reduced operational burden on legal, IT, and privacy teams through automated DSR workflows.
• Up to 3× Faster: Turnaround times for access and deletion requests.
• Centralized Audit Trail: For all DSR activity, strengthening compliance readiness and internal reporting.
• Clear Automation Expansion Roadmap: To onboard additional systems, regions, and business units.
• Stronger Cross-Functional Alignment: Between legal, security, IT, and engineering teams.

Conclusion

As Similarweb continues to grow and diversify its products, MineOS provides the foundation for scalable, auditable, and future-proof privacy operations. By moving from manual processes to controlled automation, Similarweb is transforming privacy compliance from a reactive burden into a strategic, operational capability.
