Bain & Company | Professional Services | 22000 | $7.5B | United States | Tenable | Tenable Nessus | Network Management and Monitoring | 2021 | n/a |
In 2021 Bain & Company deployed Tenable Nessus to strengthen Network Management and Monitoring capabilities for vulnerability assessment across applications, systems, and networks. Tenable Nessus was adopted as the primary automated scanner supporting security engineering and penetration testing workflows during a program executed from February 2021 to December 2023, with the tool positioned to provide repeatable vulnerability baseline data for technical and compliance stakeholders.
Configuration and operational use centered on credentialed and unauthenticated scans, custom scan policies aligned to application and infrastructure profiles, and scheduled automated discovery to surface OWASP Top 10 and SANS 25 relevant findings. Tenable Nessus outputs were used in concert with manual penetration testing and exploitation techniques, applying grey box and black box methodologies alongside Burp Suite, Nmap, and SQLmap to validate authentication, session management, encryption, and application logic vulnerabilities. Security teams produced structured technical assessment reports with reproduction steps and actionable remediation guidance derived from Nessus scan results.
Proof of concept integrations were planned and implemented to link Tenable Nessus findings into Varonis for SharePoint visibility, Kenna Risk Management for vulnerability prioritization, and Symantec DLP for data protection gating, reflecting an emphasis on toolchain orchestration. Operational coverage extended into Azure cloud security and ISAM, and encompassed SaaS, IaaS, and PaaS environments, supporting both application security and infrastructure security use cases. Business functions impacted included security engineering, Red Team operations, network security operations, and compliance teams responsible for privileged access and user access reviews.
Governance and process changes incorporated quarterly user access compliance validation and privileged access review cycles that consumed Nessus findings as part of access risk assessments. Remediation coordination followed delivery of high severity issues identified by Tenable Nessus, with validation steps documented in assessment reports and tracked through routine vulnerability management cycles. Tenable Nessus served as a core component of Bain & Company Network Management and Monitoring practices for continuous vulnerability detection and validation.

Conway Medical Center | Healthcare | 2000 | $270M | United States | Tenable | Tenable Nessus | Network Management and Monitoring | 2020 | n/a |
In 2020, Conway Medical Center deployed Tenable Nessus to operationalize its Network Management and Monitoring capability across the hospital IT estate. Tenable Nessus was positioned as the primary vulnerability scanning engine within a broader vulnerability management workflow to identify and prioritize security exposures across servers, VDI images, and endpoints.
The implementation centered on vulnerability scanning, asset discovery, scheduled scan orchestration, and reporting, with Tenable Nessus feeding standardized findings into patch orchestration processes. The environment supporting scans included a VMware virtual infrastructure for server and VDI workloads, specifically vSphere, Horizon View, and Dynamic Endpoint Manager where applicable. Configuration emphasized routine scans and integration points that supported remediation tracking rather than bespoke custom modules.
Tenable Nessus was operated alongside KACE and WSUS for scanning, patching, and reporting purposes, creating an integrated pipeline from detection to remediation. The deployment covered a hybrid Microsoft 365 estate including on-premise Exchange and SharePoint, Azure AD managed identities, and an enterprise Windows server footprint running Server 2012 R2, 2016, and 2019, with GPO, AD, DNS, DHCP, and AD certificate services in scope. Operational coverage extended to endpoint security and network access controls, aligning Nessus scan targets with routine Windows patching and endpoint operations.
Governance was structured around an internal vulnerability management process led by IT security and systems engineering staff, incorporating daily security operations, control features to meet organizational quality standards, and documented remediation workflows. The Tenable Nessus deployment supported established patching responsibilities and quality control procedures within the IT department, enabling systematic identification and remediation of critical vulnerabilities without implying quantifiable outcomes.

Hub Group | Transportation | 6604 | $3.9B | United States | Tenable | Tenable Nessus | Network Management and Monitoring | 2023 | n/a |
In 2023 Hub Group consolidated its Tenable footprint by deploying Tenable Nessus as part of a single Tenable Cloud instance. The implementation centralized Nessus Pro scanners, Security Center, and Tenable Cloud into one managed environment, enrolling more than 1,000 agents within six months to provide unified vulnerability scanning and policy enforcement. Tenable Nessus was applied within the Network Management and Monitoring category to deliver both agent and network scanning across servers and endpoints, and the program emphasized central scanner orchestration, agent enrollment, and standardized scan policies for consistency.
Operational integrations and governance steps accompanied the Tenable Nessus rollout, including a parallel Microsoft Sentinel deployment as an interim SIEM for 5,000+ users and 1,000 servers configured with 60+ event sources, 100+ analytic rules, and 10+ automation playbooks, and remediation tracking into Cisco Kenna for scanned assets. Post-acquisition work included installing Palo Alto firewalls, deploying 15 IDS appliances, and scanning 70+ servers with vulnerability findings routed into the broader remediation workflow. The program also built Python automation to standardize auditd deployment on Linux servers and to orchestrate asset onboarding, paired with policy rationalization and analyst tuning to reduce false positives. The Tenable consolidation documented improved detection accuracy by up to 70 percent and recurring cost savings of about $30,000 per year.
