The state of platform abuse today.

Threat surface area is growing.

As free online platforms grow so does the threat surface area. Direct messages, public feeds, and share functionality are a hotbed for phishing, scamming, and other types of platform abuse.

Existing anti-abuse solutions don’t cut it.

Current solutions for platform abuse revolve around human input (user or employee oversight) or blacklists. Manual solutions require significant community participation or staffing resources, and don't scale. Blacklist-based solutions often can't catch newly created phishing sites or link shortened URLS (, etc).

A world without platform abuse.

Bolster’s Scam Detection API is your platform’s secret weapon.

Real-time and Zero-day

Our API utilizes a suite of deep-learning, computer vision, and NLP models to look at a website in real-time (<100ms). Before any blacklist stores the URL – before any human has time to look at it – our technology will detect a threat against your ecosystem.
