Team Highlight

Engineering, Product & Design

We are building the foundation of the next generation of email security, leveraging AI and cloud infrastructure to stop the most advanced social engineering attacks.

Our Challenges

Complex Problems


We are creating products to serve entirely new markets such as Business Email Compromise, vendor fraud, and Cloud Office security. 

We are leading in the field of ML explainability, and integrate seamlessly with data providers and other security tools for a superior customer experience.

Machine Learning

Our detention models require extremely high precision and recall in order to identify every single attack but not overwhelm our customers with false positives. The attacks we detect are very rare, occurring in less than one in a million messages.

We face adversarial attackers that are rapidly evolving. We leverage cutting-edge machine learning models, as well as multi-dimensional datasets, to catch them.


Our products evaluate messages and sign-ins in real-time, operating at high throughput (>1M queries per second) and low latency (<0.1s). Our infrastructure must reliably support our Fortune 500 customers, even as we are rapidly scaling by over 3x each year.

Cloud-native infrastructure allows customers to integrate incredibly quickly, and it also gives us access to data unavailable to legacy on-prem vendors.
