ABOUT
We build fraud checks that explain themselves.
Lightning Research is a small engineering team. We build LR Defender because risk teams deserve answers they can defend, not scores they have to take on trust.

WHAT WE BELIEVE
Three rules we build by.
- 01
Show the reasons.
Every verdict comes back with the reasons behind it, so the team that acts on it can defend it.
- 02
Say unknown when it is unknown.
When no source covers an address and no browser check names a relay, residential proxy status reads unknown, never clean.
- 03
Publish the price.
Our prices are on the pricing page, and the free trial after a demo call needs no card.
TEAM
Who builds it. The people you reach when you write to us.

RESEARCH
Research we build on.
LR Defender builds on published research, including cross-browser fingerprinting work presented at NDSS 2017 and the DrawnApart GPU fingerprinting paper presented at NDSS 2022. We credit the authors; we do not claim their work.
