About NNSFlow
Built for compliance teams who need defensible screening documentation.

An engineer who works on critical systems daily
Antoine Bedaton, Founder
Antoine is a Critical System Engineer at Eurocontrol, the European air-traffic-control agency. He works in the middleware team, handling L2 incident response across the platforms the agency runs. The job is operational. Every day, he sees what breaks in critical-infrastructure systems and what it takes to recover.
That perspective shapes NNSFlow. Compliance teams face a structurally similar problem to incident response: when something has to be reconstructed years later, the evidence trail captured at the time is everything. Most systems are not built for that. NNSFlow is.
After founding PentaLab to bring engineering discipline to regulated industries, AML compliance stood out as the first domain to apply it to: the gap between what regulators expect (the ability to reconstruct decisions years later) and what most screening systems deliver (notes and summaries) was structurally large.

Why we built NNSFlow
The Problem
Compliance teams in financial institutions spend significant time on negative news screening. The process is manual, time-consuming, and critically: the documentation often doesn't meet the evidentiary standards regulators expect.
When a regulator asks "what did you see when you cleared this client?", most teams can only show a summary or a note. They can't reproduce exactly what sources were available, what content those sources contained, or what keywords were being searched for at the time.
Our Solution
NNSFlow was built to solve this specific problem. Every source reviewed during a screening is captured in full, hashed for integrity, and frozen at the moment of decision.
The result is a legally defensible record that proves what your team saw at the time they made their decision. This isn't about automation for its own sake -- it's about giving compliance officers the documentation they need when the regulator comes asking questions years later.
How we think about compliance tools
Evidence over summaries
A summary of what you found is not the same as proof of what you saw. NNSFlow stores the full content of every source reviewed, not just a list of URLs.
Immutability matters
Evidence that can be edited isn't really evidence. Once a screening is completed, the record is frozen. No modifications, only annotations.
Clean sources are evidence too
If you only store "risky" findings, you can't prove the clean sources were actually clean. All reviewed sources are captured, regardless of risk level.
Configuration is part of the decision
What keywords were searched? What sites were filtered? This configuration is frozen alongside the evidence, preventing "different settings" arguments.
