Nessus overview
What is Nessus?
Nessus is a cloud-based security configuration and vulnerability assessment solution designed to help security practitioners identity and resolve vulnerabilities to protect organizations against various security risks. It comes with pre-defined templates which can be customized by users to scan for critical vulnerabilities.
Key features of Nessus include asset discovery, web scanning, policy management, prioritization, and vulnerability assessment. It allows businesses to tailor scans based on individual preferences, ensuring compliance with several Center for Internet Security (CIS) benchmarks and other best practices. Security teams can generate reports on vulnerability types, export them in a range of file formats including CSV, HTML and XML, sort data by client or team, and share them via email after every scan for improving transparency across processes.
Nessus comes with a live results module, which enables users to perform offline vulnerability assessments in order to detect, validate, and prioritize issues for improving organizational security. Teams can also categorize similar vulnerabilities and present the issues in a single thread to streamline prioritization and ensure immediate remediation of issues.
