When your asset base crosses five figures, vulnerability risk management stops being a scanning exercise and becomes a risk-governance discipline. You’re no longer “running Nessus every month”; you’re orchestrating dozens of tools, teams, and processes. If you don’t, you accumulate vulnerability debt, fail audits, and expose exploitable weaknesses.
This guide is a practical playbook for CISOs, AppSec leaders, and DevSecOps teams. For each stage of the vulnerability risk lifecycle, we’ll cover:
- Why it hard at 10,000+ assets
- Concrete steps to execute
- Typical tools used by large enterprises
- Stakeholders and RACI
- Pitfalls and success metrics
At the end, we’ll show how Strobes RBVM becomes the orchestration and intelligence layer across scanners, CMDB, and ticketing.
The Vulnerability Risk Lifecycle
- Asset discovery & inventory
- Vulnerability scanning & detection
- Risk analysis & prioritization
- Remediation/mitigation
- Validation/verification
- Reporting & metrics
- Continuous feedback & improvement
1. Asset Discovery & Inventory
Objective: a single, authoritative inventory enriched with ownership and business context.
Why it’s hard:
- Multiple environments (on-prem, multi-cloud, SaaS, containers).
- Ephemeral infrastructure and shadow IT.
- M&A brings unknown devices.
Step-by-step:
- Integrate existing sources – ServiceNow CMDB, Active Directory, AWS Config, Azure Resource Graph, endpoint agents (Tanium, CrowdStrike Falcon Discover).
- Run discovery scans with Qualys Asset Inventory or Rapid7 Asset Discovery.
- Enrich records with metadata (owner, criticality, compliance scope).
- Establish ownership and SLAs for updating.
- Automate nightly imports and flag deltas.
Stakeholders: IT ops (asset owners), Security ops (scanning), Governance/Risk (criticality tags).
Pitfalls: treating CMDB as a one-off, ignoring containers, and missing SaaS.
Metrics: % assets discovered vs estimated total; % with owner assigned; median age of asset records.
3. Risk Analysis & Prioritization
Objective: Transform raw findings into an actionable queue of “fix this first”.
Why it’s hard:
- 100 000+ findings = impossible manual triage.
- Business context is often missing.
- Threat intel changes daily.
Step-by-step:
- Ingest all findings into a central RBVM platform (Strobes, Tenable Predictive Prioritization, Qualys TruRisk or Strobes).
- Apply contextual scoring: CVSS + EPSS + CISA KEV + asset criticality + exposure.
- Enrich with compensating controls (firewall, EDR).
- Define risk buckets and SLAs (Critical 7d, High 30d, etc.).
- Push prioritized tickets to ServiceNow Vulnerability Response or Jira.
Stakeholders: Security risk team, AppSec, Business owners.
Pitfalls: Relying solely on CVSS, not updating the scoring model, and not aligning with business impact.
Metrics: % critical vulns with exploit known; median prioritization latency; SLA compliance by severity.
4. Remediation / Mitigation
Objective: Fix or mitigate prioritized vulnerabilities at scale.
Why it’s hard:
- Different patch cycles per OS/application.
- Change-control windows.
- Some systems cannot be patched.
Step-by-step:
- For patchable assets, use Microsoft SCCM/Intune, Ivanti Patch or Linux package managers.
- For configuration drift,t use Ansible, Puppet, or Chef.
- For an unpatchable system, deploy compensating controls: Palo Alto firewalls, AWS Security Groups, Cloudflare WAF, and segmentation.
- Track remediation automatically via dashboards linked to CMDB and RBVM.
Stakeholders: IT ops (patching), App owners (application updates), Change management.
Pitfalls: Uncoordinated patching causing outages; no rollback plan; not validating fixes.
Metrics: MTTR by severity; % vulnerabilities remediated within SLA; number of compensating controls in place.
5. Validation / Verification
Objective: Prove that remediation actually reduced risk.
Step-by-step:
- Re-scan patched assets.
- Use drift detection to catch rollback.
- Correlate vulnerability data with exploit attempts in SIEM.
- Audit sample high-risk assets manually.
Metrics: % of remediations successfully verified; false-negative rate of scanners.
6. Reporting & Metrics
Objective: Give leadership risk metrics, not raw numbers.
What to report:
- Asset coverage (% scanned vs total).
- MTTR by severity.
- SLA compliance by business unit.
- Vulnerability backlog trends.
- Risk reduction curves over time.
Use ServiceNow dashboards, Splunk, Power BI, Grafana or the dashboards built into your RBVM (such as Strobes).
Pitfalls: vanity metrics (number of scans), no executive narrative.
7. Continuous Feedback & Improvement
Objective: Make the program adaptive.
Actions:
- Tune scanner policies, suppress false positives.
- Add new threat intel feeds.
- Include new asset classes (cloud, IoT, OT).
- Run retrospectives after major incidents (Log4Shell, MOVEit).
- Train remediation teams regularly.
Metrics: reduction in false positives; time to onboard new asset classes; incident response improvements.

Governance and Stakeholders
At 10,000+ assets, vulnerability management is no longer a “security team project.” It’s an enterprise-wide programme with defined decision rights, reporting lines, and escalation paths. Without a governance model, SLAs slip, and risk acceptance decisions happen ad hoc.
Core principles
- Accountability at the business-unit level. Each asset has an owner who is responsible for remediation decisions.
- Centralised risk policy, decentralised execution. Security defines the framework; IT and application teams execute under it.
- Documented risk acceptance. When a vulnerability can’t be fixed, the business—not Security—owns the exception.
Key Stakeholders Role
| Role | Responsibilities | Typical Titles |
| Executive Sponsor / Steering Committee | Sets overall risk appetite, approves budgets, and arbitrates conflicts between business units. | CISO, CIO, CRO |
| Vulnerability Management Lead | Owns the programme, maintains policies, coordinates across teams, and reports to leadership. | Head of AppSec, Security Manager |
| Security Operations / AppSec | Runs scanners, tunes findings, enriches with threat intel, and manages the RBVM platform. | SOC, AppSec engineers |
| IT Operations / Infrastructure | Patches OS and middleware, manages SCCM/Intune, implements configuration changes. | Infrastructure leads |
| Application Owners / DevOps | Remediate code and container vulnerabilities, manage CI/CD security gates. | Product owners, DevOps leads |
| Risk & Compliance | Ensures risk exceptions are formally documented and reviewed. | GRC teams |
| Audit / Internal Control | Periodically tests controls, verifies metrics. | Internal audit |
Operating model
- Weekly operational stand-up – security + IT to review open vulnerabilities and SLA breaches.
- Monthly steering committee – CISO/CIO/BU heads review KPIs, approve risk exceptions, allocate resources.
- Automated workflows – exceptions, approvals, and SLA tracking handled in ServiceNow or RBVM platform to remove manual email chains.
- RACI – Security is Responsible for scanning/prioritising; IT/App teams are Responsible for remediation; Execs are Accountable for risk acceptance.
Success indicators
- 100 % of assets are mapped to an owner.
- All SLA breaches are visible in dashboards with an assigned action plan.
- Risk exceptions tracked with expiry dates and executive sign-off.
Integrating Security into Your Workflow: How It Actually Works
In modern DevOps environments, security can’t be an afterthought. To truly secure your applications and infrastructure, it’s crucial to embed security checks directly into your workflow. This is where a well-designed integration workflow comes into play.
Think of it like this: from the moment a developer commits code to the repository, security should be working silently in the background, scanning for vulnerabilities and ensuring nothing risky makes it to production. A typical integration workflow looks something like this:
- Discovery & Inventory – First, all assets, applications, and dependencies are automatically identified. Knowing what you have is the foundation of effective security.
- Scanning & Assessment – The system scans code, configurations, and infrastructure for potential vulnerabilities.
- Prioritization & Remediation – Not all risks are created equal. The workflow triages vulnerabilities based on severity and business impact, ensuring critical issues get fixed first.
- Reporting & Feedback – Teams receive clear, actionable reports and alerts, making remediation faster and more efficient.
Automation is key here. By integrating security into CI/CD pipelines—whether through Jenkins, GitHub Actions, GitLab CI, or Terraform—teams can automatically catch risks early without slowing down development.Â
