Scutum is a cloud-based Web application firewall (WAF) service developed and provided by bitforest inc., a Japanese cybersecurity company specializing in web application security. The service became available in June 2009 as a result of a joint development initiative between bitforest inc. and Secure Sky Technology Inc.[1]

History

[edit]
  • June 2009: Scutum was launched through a collaboration between bitforest inc. and Secure Sky Technology Inc.[2]
  • 2013 onwards: bitforest introduced an AI-based detection engine using Bayesian network technology, replacing traditional signature-based detection.[3]
  • 2017: A machine-learning–based anomaly detection feature was made available to identify traffic deviations per site.[4]
  • August 2021: bitforest deployed its proprietary "Thinning" method based on Isolation Forests, improving detection rates by 17% while reducing false positives.[5]

Technical overview

[edit]

Scutum’s detection engine combines:

  • Bayesian networks: Probabilistic inference models to identify attack patterns.
  • Anomaly detection: Site-specific learning to flag deviations from normal behavior.
  • Thinning method: Tree preselection technique for improved classification using Isolation Forests.
