The Leaders in Digital Trust & Safety

How Sift helps companies grow securely

Our mission: Help everyone trust the internet

We believe trust and safety are fundamental to every online interaction. As the pioneers of Digital Trust & Safety, we help more than 34,000 sites and apps navigate the fine balance between growing revenue and protecting their business.

We believe users are innocent until proven guilty. A business’s good customers should never be turned away or made to jump through hoops. We make it easy for companies to remove friction and delight their customers, while keeping bad actors out.

We believe legacy technologies are holding businesses back. We were the first to use machine learning for fraud prevention, and our customers see the results every day. The speed, accuracy, and scalability of our solution is unrivaled.

The time to change is now. Customer expectations are higher than ever. Competition is fierce. Fraudsters innovate and scale as fast as businesses. That’s why thousands of websites and apps, from digital disrupters to Fortune 500 companies, partner with Sift.
