The Threat
Global CDNs often route traffic through US servers, creating data residency risks.
The Impact
Potential GDPR non-compliance and exposure to third-country data transfer laws.
Legacy Failure
Traditional CAPTCHAs often rely on US-based processors that collect and export user telemetry.
The Solution
Localized, deterministic hardware attestation executed entirely within the EU.
Many global CDNs route traffic through US-based points of presence. This can lead to the transfer of personal data, such as IP addresses and browser fingerprints, to jurisdictions with different data protection standards, complicating GDPR compliance.
TrustSig is built on an edge-first architecture designed to process all telemetry and verification logic within EU-based infrastructure, ensuring your data residency strategy remains clean and simple.
Instead of using visual puzzles, we validate the hardware and telemetry signatures of the requesting client. This allows us to mathematically prove the authenticity of a device without needing to export data to third-party US processors.
The Anatomy of the CDN Dilemma
In our experience, many organizations rely on global Content Delivery Networks (CDNs) to optimize performance. While these networks are excellent for speed, they often introduce a hidden risk: data residency. When your traffic is routed through a global CDN, it frequently passes through points of presence (PoPs) located in the United States.
For European businesses, this creates a significant compliance challenge. Under the GDPR, transferring personal data to third countries requires strict safeguards. When your security tools—specifically legacy CAPTCHA services—are also based in the US or route data there for processing, you are effectively exporting your users' behavioral data without full control.
Why Legacy Defenses Complicate Compliance
If you look at the privacy policies of many common bot detection services, you will find that they often process data in the US. Whether it is Google reCAPTCHA or other third-party providers, these services frequently collect:
- IP addresses
- Browser fingerprints
- Mouse movements and interaction patterns
- Device settings
When these tools are embedded on your site, you are acting as a controller sharing data with a third-party processor. If that processor is based in the US, you must ensure that the transfer is covered by adequate safeguards, such as standard contractual clauses. In our opinion, this adds unnecessary legal and operational overhead to your security stack.
Deterministic Bot Mitigation at the Edge
We believe that security should not come at the cost of privacy. TrustSig was built to solve this dilemma by moving the verification process to the edge, while keeping the data within the EU.
Instead of relying on third-party puzzles that track user behavior and export it to US servers, we use deterministic hardware attestation. By analyzing the hardware-level telemetry of the client—such as WebGL rendering fingerprints and CPU concurrency—we can verify if a request is coming from a genuine consumer device or a bot.
This process is:
- Localized: All verification logic happens within EU-based infrastructure.
- Deterministic: We do not rely on probabilistic scoring that requires massive data sets sent to foreign servers.
- Invisible: Your users never have to solve a puzzle, and you never have to worry about the privacy implications of third-party tracking.
By choosing a privacy-first, edge-first approach, you can protect your infrastructure from automated threats while maintaining full control over your data residency.
