Delivering Measurable Security Improvements Through Vulnerability Management

Challenge

Our telecommunications client needed to strengthen its security posture amid growing network complexity and increasing cyber threats. While the organization had security tools in place, its vulnerability management and incident response processes lacked the maturity, consistency, and visibility required to proactively identify and mitigate risk.

Our client required an experienced Vulnerability Management Engineer who could work onsite, take ownership of the vulnerability lifecycle, and improve detection, response, and remediation across network operations, without disrupting critical service delivery.

Solution

ClearBridge provided a Vulnerability Management Engineer who led efforts to modernize and operationalize the client’s vulnerability management and security operations capabilities.

Key contributions included:

• Designing and implementing vulnerability management infrastructure and processes using Qualys and Tenable/Nessus
• Enhancing network security through optimized configurations of Palo Alto firewalls and load balancing technologies
• Correlating security-relevant system and application logs to improve alerting and threat detection
• Leading the security incident response lifecycle, including coordination of countermeasures and remediation
• Analyzing and refining existing security logic to improve threat detection and response efficiency
• Serving as a central point of collaboration across security, network, and operations teams

​Impact

• Improved visibility into vulnerabilities and security events across the network
• Faster and more effective incident detection, response, and remediation
• Reduced security risk through proactive vulnerability identification and remediation
• Stronger alignment between security operations and network engineering teams
• A scalable vulnerability management program supporting long-term operational resilience
