FAQs

What is Tenable Security Center?

Tenable Security Center and Tenable Security Center Plus are Tenable’s on-premises vulnerability management solutions. Built on industry-leading Nessus technology, the Tenable Security Center family of products identifies, investigates and prioritizes vulnerabilities, providing you with a risk-based view of your security and compliance posture. For more information on these solutions, please see the Tenable Security Center Data Sheet and Tenable Security Center Plus Data Sheet.

What is the difference between Tenable Security Center and Tenable Security Center Plus?

Tenable Security Center Plus is a vulnerability management platform that builds off of the functionality in Tenable Security Center and includes cyber risk metrics found in Tenable Lumin for an additional layer of context for your assets and vulnerabilities. These metrics provide a more tailored approach to your vulnerability management program, all calculated on your Tenable Security Center Plus instance, so your data remains on-premises. Additionally, Tenable Security Center Plus can integrate with Tenable’s Exposure Management platform, Tenable One, to increase the value of the insights provided by Security Center Plus.

Does Tenable Security Center work with Tenable One?

Yes! Tenable Security Center Plus integrates with Tenable One to provide hybrid vulnerability management deployments and allow on-premises customers to take advantage of an exposure management platform.

What is Tenable One?

Tenable One is an exposure management platform to help organizations gain visibility across the modern attack surface, focus efforts to prevent likely attacks and accurately communicate cyber risk to support optimal business performance. The platform combines the broadest vulnerability coverage spanning IT assets, cloud resources, containers, web apps and identity systems, builds on the speed and breadth of vulnerability coverage from Tenable Research and adds comprehensive analytics to prioritize actions and communicate cyber risk. Tenable One allows organizations to:

• Gain comprehensive visibility across the modern attack surface
• Anticipate threats and prioritize efforts to prevent attacks
• Communicate cyber risk to make better decisions

What is Tenable Security Center Director?

Tenable Security Center Director is an add-on to Tenable Security Center. It provides enterprise customers with a unified view across their large and often dispersed network spanning multiple Tenable Security Center consoles. Tenable Security Center Director gives complete visibility and management of your instances so you can focus on vulnerability management and reduce overhead on administrative tasks.

Does Tenable Security Center work with Tenable Web App Scanning?

With Tenable Security Center version 6.2, Tenable enhances your defenses by adding on-premises web application security. Seamlessly integrated into the Security Center UI, Tenable Web App Scanning empowers you to identify and address vulnerabilities across your network and web applications, bolstering your security posture.

Tenable Web App Scanning is a dynamic application security testing (DAST) tool which thoroughly assesses web applications. It crawls the web app to create a site map, then scans the front end to detect vulnerabilities in custom code and third-party components.

What is Predictive Prioritization and how does it help prioritize vulnerabilities?

Predictive Prioritization combines Tenable-collected vulnerability data with third-party vulnerability and threat data and analyzes them together with the advanced data science algorithm Tenable Research developed. Each vulnerability receives a Vulnerability Priority Rating (VPR) that represents the likelihood an attacker may exploit a given vulnerability in the next 28 days along with its severity. You can use VPR to understand actual cyber risk of vulnerabilities in their unique environments so you can prioritize remediation efforts on vulnerabilities with the greatest impact.

How does Tenable Security Center find assets and vulnerabilities?

Using a diverse array of sensors, Tenable Security Center ensures continuous discovery and assessment of your network, assets and vulnerabilities in real-time.

Tenable Security Center gathers security data from across your organization using sources such as:

• Passive monitoring: Monitoring network traffic and events in real-time provides information on which assets are connected to the internet and how they communicate. It identifies new or never-before-seen devices or applications and detects suspicious behavior as it happens.
• Active scanning: Thoroughly analyzes asset state to identify vulnerabilities, misconfigurations, malware and other weaknesses.
• Host data: Actively monitors host activities and events, including insight into access and changes.
• Intelligent connectors: Leveraging your other security investments, Tenable Security Center can integrate additional security data to improve context and analysis. Both will analyze information from a wide range of data sources including Active Directory (AD), configuration management databases (CMDBs), patch management systems, mobile device management (MDM) systems, cloud platforms, web applications and more.
• Agent scanning: Instantly audit transient or hard-to-scan assets that intermittently connect to the internet without credentials. Once installed, agents can run credentialed scans without ongoing host credentials.

What are Nessus Agents? How do they work with Tenable Security Center?

Nessus Agents are lightweight programs installed locally on a host — a laptop, virtual system, desktop and/or server. Agents receive scanning instructions from a central Nessus Manager server, perform scans locally, and report vulnerability, compliance and system results back to the central server. Nessus Agents are available with Tenable Vulnerability Management and Tenable Security Center.

Nessus Agents with Tenable Security Center increase scan coverage and remove blind spots by making it easier to scan problematic assets such as those needing ongoing host credentials and offline assets. Agents also enable large-scale concurrent scanning with little network impact.
