Your data is crucial

Data is the lifeblood of every modern business. Fast access isn’t enough. Secure data isn’t enough. To succeed, you need both.

Your data is everywhere

Employees, vendors and customers expect seamless access to your data — from anywhere and at any time.

Your data is vulnerable

Data is also extremely vulnerable and as cyber attacks and insider threats increase, data breaches are inevitable.

The Ultimate Safety Net

If all else fails and your data is exposed, with Nullafi it simply won’t matter. It’s a new approach to data security – you deserve to get ahead of the problem, not just react to it.

Ultra-Light and Flexible

Whether you have 20 thousand data records or 20 million, cloud-delivered and lightweight means Nullafi is quick to deploy and scale, and can meet your unique data needs.

Unparalleled Security

Our first customers were other cybersecurity companies because our solutions are zero-knowledge by design. We decrease your overall risk footprint, not add to it.


Like your existing tools? Great–not only do we integrate well with other security products, we strengthen their efficacy.


We can’t see your data even if we want to. We’ve built our system on a zero-knowledge framework, meaning we aren’t simply a risk-shifting method or an additional risk for you.

Reversible Anytime

It’s as easy to reverse as it is to implement. Change the data you protect any time according to your accessibility and security needs with our simple API.
