Nessus Professional, the industry’s most widely deployed vulnerability assessment solution helps you reduce your organization’s attack surface and ensure compliance. Nessus features high-speed asset discovery, configuration auditing, target profiling, malware detection, sensitive data discovery, and more.
Nessus supports more technologies than competitive solutions, scanning operating systems, network devices, hypervisors, databases, web servers, and critical infrastructure for vulnerabilities, threats, and compliance violations.
With the world’s largest continuously-updated library of vulnerability and configuration checks, and the support of Tenable, Inc.’s expert vulnerability research team, Nessus sets the standard for vulnerability scanning speed and accuracy.
Note: Nessus Manager is no longer sold as of February 1, 2018. For existing standalone Nessus Manager customers, service will continue to be provided through the duration of your contract. Nessus Manager will continue to be supported and provisioned for the purposes of managing agents.
Nessus Manager combines the powerful detection, scanning, and auditing features of Nessus, the world’s most widely deployed vulnerability scanner, with extensive management and collaboration functions to reduce your attack surface.
Nessus Manager enables the sharing of resources including Nessus scanners, scan schedules, policies, and scan results among multiple users or groups. Users can engage and share resources and responsibilities with their co-workers; system owners, internal auditors, risk and compliance personnel, IT administrators, network admins and security analysts. These collaborative features reduce the time and cost of security scanning and compliance auditing by streamlining scanning, malware and misconfiguration discovery, and remediation.
Nessus Manager protects physical, virtual, mobile and cloud environments. Nessus Manager is available for on-premises deployment or from the cloud, as Tenable.io. Nessus Manager supports the widest range of systems, devices and assets, and with both agent-less and Nessus Agent deployment options, easily extends to mobile, transient and other hard-to-reach environments.
For Nessus Agent documentation, see the Nessus Agent User Guide.
Nessus Agents, available with Tenable.io and Nessus Manager, increase scan flexibility by making it easy to scan assets without needing ongoing host credentials or assets that are offline, as well as enable large-scale concurrent scanning with little network impact.
Nessus Agents are lightweight, low-footprint programs that you install locally on hosts to supplement traditional network-based scanning or to provide visibility into gaps that are missed by traditional scanning. Nessus Agents collect vulnerability, compliance, and system data, and report that information back to a manager for analysis. With Nessus Agents, you extend scan flexibility and coverage. You can scan hosts without using credentials, as well as offline assets and endpoints that intermittently connect to the internet. You can also run large-scale concurrent agent scans with little network impact.
Nessus Agents help you address the challenges of traditional network-based scanning, specifically for the assets where it's impossible or nearly impossible to consistently collect information about your organization's security posture. Traditional scanning typically occurs at selected intervals or during designated windows and requires systems to be accessible when a scan is executed. If laptops or other transient devices are not accessible when a scan is executed, they are excluded from the scan, leaving you blind to vulnerabilities on those devices. Nessus Agents help reduce your organization’s attack surface by scanning assets that are off the network or powered-down during scheduled assessments or by scanning other difficult-to-scan assets.
Once installed on servers, portable devices, or other assets found in today’s complex IT environments, Nessus Agents identify vulnerabilities, policy violations, misconfigurations, and malware on the hosts where they are installed and report results back to the managing product. You can manage Nessus Agents with Nessus Manager or Tenable.io (including Tenable.io on-prem).
