Insights from Karlsgate On Safe and Privacy-Compliant Data Sharing

The Pressure Test for Privacy-First Platforms

Written by Brian Mullin | May 14, 2025

In our last post, we explored the growing number of platforms claiming to be “privacy-first”, and the questions you should be asking to understand what’s really going on behind the scenes. 

This time, we’re going a layer deeper. 

Because even when those platforms sound “good enough” on the surface, the real-world demands of data collaboration expose just how fragile and inflexible many of them really are. 

One Size Doesn’t Fit Your Data 

Most “privacy-first” platforms treat collaboration as a predefined workflow: 

Match records using hashed emails, MAIDs, cookies, or other basic match keys. That’s it. 

But real data isn’t that simple. 

Your use cases may require: 

  • More complex match keys that reflect business logic, 
  • Domain-specific identifiers beyond standard digital IDs, or 
  • A way to work with data that’s messy, inconsistent, or non-standard. 

These platforms don’t offer that. And they rarely include built-in tools to help: 

  • Normalize and standardize diverse data inputs, 
  • Detect semantic inconsistencies across files, or 
  • Automate best-practice composite key generation for high-quality matching.

Precision at scale requires more than a one-size-fits-all data linkage approach. 
If your data doesn’t fit their system, you adapt or you pay.

The Hidden “Tariff” on Every Trade 

Even when platforms say they support collaboration at scale, there’s a hidden tariff, and it’s not just about price. 

It’s also about time, manual effort, and how little the system helps you out. 

  • Most platforms don’t include built-in workflows to automate onboarding, 
  • They don’t adapt to different partner environments or handle variability well, and 
  • Because they lack robust data handling, they force users to do the heavy lifting; over and over again. 

Each new partner. Each new data set. Each new use case. 
It all adds up. 

And for many organizations, that means: 

  • Collaboration takes months, not days, 
  • Valuable use cases are dropped because they’re “too hard”, and 
  • Your team is stuck doing repetitive, error-prone work the platform should be handling. 

In a world where data needs to move fast and budgets are tight; you can’t afford a separate solution for every use case.

You need a data collaboration solution that handles all of them efficiently, consistently, and at scale. 

If your system can’t scale without scaling your technical effort, that’s not a solution. That’s a bottleneck.

 

Legal Compliance Shouldn’t Be an Afterthought  

Most platforms claim to be privacy-first. But when it comes to regulatory alignment, architecture matters more than marketing. 

Can your collaboration model meet the technical and operational standards set by laws like: 

  • GDPR, which demands data minimization, purpose limitation, and transparency about processing roles? 
  • HIPAA, which outlines specific de-identification standards like Safe Harbor and Expert Determination? 
  • CCPA and CPRA, which grant individuals rights to access, delete, and restrict data, even when it’s pseudonymized? 
  • Cross-border data regulations, which limit the movement and processing of data outside approved jurisdictions? 

These aren’t vague principles. They require technical enforcement, not just paperwork. 

Yet many platforms still: 

  • Use persistent identifiers across workflows and partners, 
  • Depend on shared infrastructure where roles blur, and 
  • Place enforcement in the hands of someone other than the data owner.

Contracts are important, but if your architecture can’t enforce the regulations, you’re not compliant. 
Compliance should be built in, not just negotiated

 

Conclusion: Privacy-First Solutions Must Be Pressure-Tested 

It’s not enough to say, “data is protected.” 
The real question is:

Can your collaboration model handle real use cases, real timelines, and real constraints, without making you compromise on control, compliance, or speed? 

Because when collaboration is slow, rigid, or expensive, your opportunity cost grows. 
And when protection depends more on paperwork than on technology, your risk grows too. 

Karlsgate was built to address these pressures at every layer with: 

  • Automated data prep and match key creation to support complex, high-quality linkage regardless of the partner or dataset,  
  • Built-in tools that streamline onboarding, reduce manual efforts, and eliminate custom engineering for every new collaboration, and 
  • A self-sovereign architecture that keeps identifiers (including pseudonyms) local, data under your control, and compliance enforced by design. 

So go ahead and pressure test your process. Ask the tough questions. 
At Karlsgate, we’ve already asked them. 
And our answers hold up.
