ServiceNow Security Operations – Vulnerability Response Transformation Case Study

The client organization managing over 20,000 servers, workstations, network devices, databases, and cloud resources across multiple data centers and cloud environments. The organization utilized Tenable for vulnerability scanning but relied heavily on manual processes to track remediation activities, resulting in delayed vulnerability resolution and increasing cyber risk.

Business Challenges

Lack of Centralized Vulnerability Management and Security teams received vulnerability findings from Tenable, but remediation activities were managed through emails, spreadsheets, and separate ticketing systems.

Thousands of vulnerabilities were discovered during monthly and weekly scans. Security teams struggled to prioritize remediation efforts because all findings were treated similarly regardless of business impact.

Manual Remediation Tracking , Security analysts manually created tickets and assigned remediation activities to infrastructure teams.

Infrastructure teams lacked visibility into their assigned vulnerabilities and associated risk levels.

Audit and Compliance Challenges, the organization was required to demonstrate vulnerability remediation compliance during regulatory audits.

Asset information existed across CMDB, cloud platforms, endpoint management tools, and network systems.

Security teams frequently encountered difficulties identifying asset owners and business services impacted by vulnerabilities.

There was no automated workflow to create remediation tasks, assign ownership, track progress, or verify remediation completion

Arohak’s Solution

Arohak implemented ServiceNow Security Operations Vulnerability Response integrated with Tenable Vulnerability Management to establish a centralized, risk-based vulnerability management program.

The solution automated the entire lifecycle from vulnerability detection through remediation and closure while providing visibility to security, infrastructure, and executive stakeholders.

Key Components of Arohak’s Solution Included

Tenable Integration - Implemented out-of-the-box integration between Tenable and ServiceNow Vulnerability Response.
Vulnerable Item Management - Configured Vulnerable Items to represent vulnerabilities discovered on individual assets.
Remediation Task Automation - Configured remediation rules to automatically generate Remediation Tasks and routed directly to responsible infrastructure teams. This eliminated manual ticket creation.
Risk-Based Prioritization - Implemented contextual risk scoring so security teams could focus on vulnerabilities posing the highest business risk rather than simply addressing findings based on scanner severity.

Results Delivered

The ServiceNow Vulnerability Response implementation significantly improved the client's overall security posture by automating the end-to-end vulnerability management process from detection through remediation. Integration with Tenable enabled automatic creation and assignment of remediation tasks, reducing manual effort and accelerating vulnerability resolution.

Business Impact

Reduced Critical Vulnerability Backlog by 75% by Automated prioritization and remediation workflows enabled infrastructure teams to focus on the most critical risks.

Reduced Remediation Time by 60% ,the average time required to remediate critical vulnerabilities decreased substantially due to automated task creation, ownership assignment, and SLA tracking.

Eliminated Manual Ticket Creation by integrating between Tenable and ServiceNow removed the need for security analysts to manually create remediation tickets, saving hundreds of hours annually.

Improved Asset Ownership Visibility by leveraging CMDB relationships and ownership data, vulnerabilities could be automatically assigned to the correct support teams, reducing assignment delays and improving remediation efficiency.

Increased Audit Readiness, the organization gained complete traceability from vulnerability detection through remediation and closure.

Audit preparation time was reduced significantly because all remediation evidence was available within ServiceNow.

Leadership gained access to real-time dashboards and risk metrics, enabling informed decision-making and proactive management of cybersecurity risks.
