Vulnerability Scanning for Compliance: What You Need to Know

The Cost of Non-Compliance

Failing to meet vulnerability scanning requirements carries consequences that go far beyond audit findings. Each framework has its own enforcement mechanisms, and the penalties are substantial.

• FedRAMP -- Authorization revocation and loss of government contracts. Agencies can suspend or terminate an ATO if continuous monitoring requirements are not met, cutting off access to the entire federal market.
• PCI-DSS -- Fines ranging from $5,000 to $100,000 per month from card brands, and potential loss of the ability to process card payments entirely. Acquiring banks pass these fines through to merchants.
• HIPAA -- Civil penalties up to $2 million per violation category per year, with OCR enforcement actions that include mandatory corrective action plans and multi-year monitoring.
• DFARS/CMMC -- Loss of Department of Defense contracts and potential False Claims Act liability for misrepresenting compliance status. CMMC Level 2 and above require third-party assessment.
• SOC 2 -- While not a regulatory mandate, a qualified or adverse SOC 2 report results in loss of customer trust and the inability to sell to enterprise customers who require it as a vendor prerequisite.

Scanning Frequency Requirements

Each compliance framework specifies different scanning cadences. Understanding these requirements is critical for designing a program that stays ahead of audit cycles.

• FedRAMP -- Monthly operating system and infrastructure vulnerability scans are required. Annual penetration testing must be performed by an independent assessor. High-severity findings must be remediated within 30 days.
• PCI-DSS -- Quarterly scans by an Approved Scanning Vendor (ASV) are mandatory for external-facing systems. Internal scans are required quarterly and after any significant infrastructure change.
• HIPAA -- The Security Rule requires regular risk analysis but does not mandate a specific scanning frequency. In practice, OCR expects evidence of ongoing technical evaluation, and annual risk assessments are the accepted minimum.
• SOC 2 -- Scanning frequency depends on the control design described in the SOC 2 Type II report. Controls may specify continuous, weekly, monthly, or quarterly scanning. The key is that actual practice matches the documented controls.
• CISA BOD 22-01 -- The Binding Operational Directive requires federal agencies to remediate Known Exploited Vulnerabilities (KEV) within specific deadlines, typically 14 days for internet-facing systems and 25 days for all others.

Evidence Requirements: What Auditors Want to See

Running scans is only half the battle. Auditors need documented evidence that your scanning program is consistent, comprehensive, and tied to a remediation process.

• Scan reports with timestamps -- Every scan must produce a dated report that shows what was scanned, when, and what was found. Reports must be retained for the duration required by the framework (typically 12 months for FedRAMP, 12 months for PCI-DSS).
• Remediation timelines -- Auditors expect to see evidence that findings were triaged and remediated within the required SLAs. This means tracking the time from discovery to resolution for every finding.
• Plan of Action and Milestones (POA&M) -- For FedRAMP and DFARS, unresolved findings must be documented in a POA&M with specific milestones and responsible parties.
• Risk acceptance documentation -- When a finding cannot be remediated immediately, auditors want to see a formal risk acceptance signed by an authorized individual, with compensating controls documented.

Building a Compliant Scanning Program

A compliant scanning program is not just about tooling. It requires process, documentation, and integration with your development workflow.

• Automate scans in CI/CD -- Integrate vulnerability scanning into your build pipeline so that every container image and artifact is scanned before deployment. This creates a natural audit trail tied to your release process.
• Maintain scan history -- Retain all scan reports with timestamps. Auditors will ask for historical data to verify that scanning was performed consistently, not just before the audit.
• Track remediation SLAs -- Define severity-based remediation timelines (e.g., critical within 15 days, high within 30 days) and track compliance against those SLAs.
• Use EPSS to prioritize -- The Exploit Prediction Scoring System provides probability scores for CVE exploitation. Using EPSS to prioritize remediation demonstrates a risk-based approach, which auditors increasingly expect to see. Learn more in our EPSS guide.
• Document exceptions -- Every accepted risk, deferred remediation, or false positive suppression must be documented with a rationale and an approver. Undocumented exceptions are audit failures.

How ScanRook Generates Compliance-Ready Output

ScanRook is designed to produce scan output that meets the evidence requirements of major compliance frameworks without additional post-processing.

• Timestamped JSON reports -- Every scan produces a structured JSON report with scan start time, completion time, scanner version, and target metadata. These reports serve as primary evidence artifacts for auditors.
• EPSS and KEV enrichment -- Findings are automatically enriched with EPSS probability scores and CISA KEV membership, providing the data needed to demonstrate risk-based prioritization. See our CISA KEV guide for details.
• SBOM generation -- ScanRook can produce Software Bills of Materials in CycloneDX and SPDX formats, satisfying Executive Order 14028 requirements for software supply chain transparency.
• Structured output for GRC tools -- The JSON report format is designed to be easily parsed and imported into governance, risk, and compliance (GRC) platforms for centralized tracking and reporting.

Enterprise Compliance Features

For organizations that need to operationalize compliance scanning at scale, the ScanRook Enterprise tier includes additional capabilities designed for regulated environments: compliance reporting templates mapped to specific frameworks, scheduled scanning with configurable cadences, data retention policies that match your audit cycle requirements, and audit log export for integration with SIEM and GRC platforms.
