SOLE SOURCE TECHNOLOGY Nessus Professional Vulnerability Assessment Software

Run vulnerability assessments with Nessus Professional to identify security findings across systems and services in scope for an assessment program. The software supports authenticated and unauthenticated scanning workflows, helping security and infrastructure teams examine exposed services, installed software, configuration conditions, and known vulnerability findings. Results can be used to prioritize remediation work and to recheck assets after corrective action. GS-SERV-NES-USSS3-SST applies to Nessus Professional performance beginning August 22, 2026, and ending August 21, 2027. That fixed date range matters when aligning assessment activity to a security operations calendar, a recurring internal review cycle, or a planned renewal date. The item is marked NCNR, so the stated term and edition should be reviewed against the required deployment before ordering. Nessus Professional is the professional vulnerability-assessment edition rather than a physical appliance or network hardware component. It fits environments where administrators need a dedicated scanner for recurring host, network, and service assessments, including scans that use authorized credentials for deeper inspection. Use it to establish a current vulnerability baseline, investigate newly exposed systems, validate remediation, and maintain regular technical visibility between larger security reviews. The defined period of performance distinguishes this order from an open-ended software purchase or a hardware support entitlement.
