Eliminate security blindspots before they become threats

Identifying and Monitoring All
Internet-Exposed Assets
- Problem: Organizations struggle to track their expanding digital footprint, leaving critical assets unmonitored and vulnerable.
- Solution: Siemba continuously discovers and monitors all external-facing assets, providing real-time visibility into exposure risks. With instant alerts on new or misconfigured assets and seamless integration into security workflows, teams can proactively secure their attack surface before threats emerge.

Detecting Unauthorized or Forgotten Assets
- Problem: Shadow IT, misconfigured cloud services, and abandoned assets create security gaps that often go unnoticed.
- Solution: Siemba detects hidden, unauthorized, and forgotten assets before attackers exploit them. With automated discovery and real-time monitoring, security teams can identify orphaned systems, eliminate unmanaged risks, and maintain full control over their external attack surface.

Prioritizing Remediation Efforts Based on Risk
- Problem: Without risk-based prioritization, security teams waste time on low-impact vulnerabilities while critical threats remain unaddressed.
- Solution: Siemba correlates and contextualizes vulnerabilities based on asset criticality,severity, exploitability, threat indicators and business impact. By automating risk-based prioritization, teams can focus on the most pressing threats first, accelerate remediation, and strengthen their overall security posture.
