Defeating malicious bots stealing valuable financial content and data is a global financial portal and internet brand composed of 30 editions in 22 languages and mobile apps for Android and iOS that provide financial news, analysis, streaming quotes and charts.

Challenge needed a solution that would detect and mitigate malicious actors’ bots that harvested valuable data and content for other exploitative purposes. The team was facing 30-40M content scraper requests per week that they needed to mitigate.


After deploying Signal Sciences on-premise in their data center,’s DevOps and network operations teams now see how and when scrapers are attempting to steal data from them—and block that activity at scale. They also gained visibility into malicious actors’ “below the radar” bot request patterns that are smaller in scope in an effort to avoid detection.

  • Security that enables the CI/CD pipeline
  • ATO and bot protection with minimal effort

Preventing Wire Fraud

Snapdocs offers a loan closing automation application for the mortgage industry that provides a workflow for buyers, lenders, title and escrow representatives, and notaries.


To prevent fraud, Snapdocs sought to identify malicious actors’ requests and other attack event patterns to prevent account takeovers. Additionally, they wanted faster visibility into attackers’ web requests in order to trigger alerts to stop them.


To enhance the security of their digital toolset for mortgage closing, Snapdocs installed the Signal Sciences NGINX module and enabled blocking mode in production within 48 hours. After doing so, they not only blocked potential attacks but gained significant visibility provided by Power Rules.



  • Gain additional flexibility necessary to prevent attacks against known tactics
  • Streamline operations with alerts that surface security events quickly
