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 became available as a SaaS-based WAF through a collaboration between bitforest inc. and Secure Sky Technology Inc. Independent coverage by technology media such as ASCII.jp noted its affordability, ease of deployment, and detection logic designed to reduce false positives.[1]
  • 2013 onwards: bitforest introduced an AI-based detection engine using Bayesian network technology, replacing traditional signature-based detection.[2]
  • 2017: A machine-learning–based anomaly detection feature was made available to identify traffic deviations per site.[3]
  • August 2021: bitforest deployed its proprietary "Thinning" method based on Isolation Forests, improving detection rates by 17% while reducing false positives.[4]

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.
