Vulnerability Management & Security Hardening
Continuous Discovery, Prioritization & Remediation for Modern Infrastructure
Expert vulnerability management services including automated scanning, risk-based prioritization, patch management, CIS benchmark compliance, Secure Score optimization, and audit-ready evidence for hosts, containers, cloud workloads, and CI/CD pipelines.
Project-Based Vulnerability Management Services
Fedlin provides comprehensive vulnerability management and security hardening services for organizations struggling with vulnerability overload, compliance requirements, or limited security resources. Whether you need continuous vulnerability scanning, patch management automation, CIS benchmark compliance, or Secure Score improvements, we deliver practical, prioritized remediation programs that reduce risk while fitting your operational constraints.
Unlike vulnerability scanners that dump thousands of findings on your team, we provide risk-based prioritization, remediation playbooks, automated remediation scripts, and evidence collection that your team can execute immediately. Our security engineers have implemented vulnerability management programs for healthcare, financial services, SaaS, manufacturing, and government organizations across cloud, hybrid, and on-premises environments.
We assess hosts, containers, Kubernetes workloads, cloud configurations, CI/CD pipelines, and infrastructure-as-code with continuous scanning, automated prioritization, and integrated remediation workflows. Available for Corp-to-Corp (C2C) engagements, project-based consulting, fractional security engineering, and technical implementation support.

Our Vulnerability Management Process
Asset Discovery & Inventory
Comprehensive asset discovery using network scanning, cloud API enumeration, and agent deployment. Build complete inventory including shadow IT, cloud resources, containers, and endpoints.
Continuous Vulnerability Scanning
Deploy automated scanning infrastructure with daily/weekly schedules, authenticated scans, and integration with cloud-native security tools. Configure scan policies, credentials, and discovery methods.
Risk-Based Prioritization
Apply risk scoring considering CVSS, exploit availability, asset criticality, exposure, and threat intelligence. Prioritize critical and high-risk vulnerabilities using CISA KEV catalog and business impact analysis.
Remediation & Hardening
Execute remediation playbooks with patch deployment, configuration hardening, and security baseline enforcement. Use automation (Ansible, PowerShell) for consistent, repeatable remediation at scale.
Validation & Evidence Collection
Verify remediation success with re-scanning, collect compliance evidence, document exceptions, and update risk register. Provide audit-ready reports with before/after validation.
Continuous Improvement & Reporting
Track KPIs (MTTD, MTTR, vulnerability density), provide executive dashboards, tune detection rules, optimize workflows, and continuously improve vulnerability management maturity.
Common Vulnerability Management Projects
Building a comprehensive vulnerability management program from scratch including tool selection, scanner deployment, policy configuration, remediation workflows, KPI dashboards, and team training.
