  • Nessus

    Nessus

    Extend Your IT Security Power, Anywhere

    The ACAS solution enables you to deploy multiple Nessus scanners across the enterprise, creating the foundation for DISA-mandated vulnerability scanning, assessment, and management capabilities. They detect and discover data and weaknesses and then report back to SecurityCenter’s advanced vulnerability analytics engine. SecurityCenter schedules and initiates Nessus scans, retrieves results, and customizes the data via reports so you can accurately assess risk and prioritize remediation workflows.

    Nessus scanners used via SecurityCenter enable you and your teams to achieve:

    • Effective resource allocation to improve efficiency
    • Expanded scan coverage across the entire IT environment
    • Improved risk analysis by integrating context from existing infrastructures and partner frameworks
    • Deep integration with core technologies so you can see and leverage additional security investments and technologies

  • PVS

    Passive Vulnerability Scanner

    Modern View for the Modern Cyber Defender

    Tenable’s Passive Vulnerability Scanner (PVS) delivers real-time network monitoring and profiling for continuous scanning and assessment of an organization’s security in a non-intrusive manner. PVS monitors network traffic at the packet level to provide visibility into both server and client-side vulnerabilities with full asset discovery.

    Additionally, PVS easily installs in networks and passively detects devices on your network, including virtual- and cloud-based devices, BYOD/mobile devices and even discovers jailbroken iOS devices. PVS scales to meet future demand of monitoring virtualized systems, cloud services, and the proliferation of devices.

    This is how you effectively create and manage a more modern view of the IT infrastructure you’re tasked with defending.
