Continuous Discovery

Point-in-time scans miss vulnerabilities introduced between assessments. Our continuous scanning program identifies new vulnerabilities as they emerge—from newly disclosed CVEs to configuration drift that introduces exposure. Your security posture is monitored, not snapshots.

Risk-Prioritized Remediation

Not all vulnerabilities are equal. We score findings using CVSS with context-aware adjustments for asset criticality, exploitability in the wild, exposure level, and business impact. Your team fixes the vulnerabilities that matter most first—not just the ones with the highest generic score.

Compliance Mapping

Every vulnerability maps to specific compliance controls in CMMC, HIPAA, PCI DSS, SOC 2, and NIST 800-171. Assessment reports provide auditors with evidence of your vulnerability management program and demonstrate continuous improvement in your security posture over time.

Managed Service Option

From scan-and-report to fully managed vulnerability management, we scale our service to your team's capabilities. Managed service includes scan scheduling, results analysis, false positive validation, remediation guidance, patch coordination, and trend reporting—delivered as a turnkey program.

Vulnerability Assessment vs. Penetration Testing: Complementary Approaches

Breadth vs. Depth: Two Essential Security Perspectives
Vulnerability assessment and penetration testing serve different but complementary purposes in a mature security program. Vulnerability assessment focuses on breadth: systematically scanning your entire attack surface to identify known vulnerabilities, misconfigurations, and policy violations across every asset. It answers the question "What vulnerabilities exist?" Penetration testing focuses on depth: manually exploiting specific vulnerabilities to prove real-world impact and demonstrate what an attacker could achieve. It answers the question "What can an attacker actually do?"
Filling the 364-Day Gap Between Annual Pen Tests
Organizations that rely solely on annual penetration tests have 364 days per year where new vulnerabilities go undetected. Vulnerability assessment fills this gap with continuous or frequent scanning that catches new CVE disclosures, configuration changes, unpatched software, exposed services, and credential weaknesses as they emerge. When your next penetration test reveals fewer findings because vulnerability assessment caught and remediated issues throughout the year, both services have done their job.
Managing Thousands of Findings With Expert Analysis
The challenge with vulnerability assessment is not finding vulnerabilities—modern scanners are remarkably thorough. The challenge is managing the output. Enterprise environments routinely generate thousands of findings per scan. Without expert analysis, false positives consume remediation effort. Without risk prioritization, teams fix easy low-impact issues while critical vulnerabilities languish in backlog. Without trend tracking, organizations cannot demonstrate security improvement to auditors or leadership. Petronella Technology Group, Inc.'s managed vulnerability assessment service addresses each of these challenges: we validate findings, prioritize by real-world risk, track remediation progress, and provide the reporting that demonstrates your security program's maturity and continuous improvement.
Comprehensive Coverage: Network, Cloud, Web, and Containers
Our vulnerability assessment methodology covers network infrastructure (servers, workstations, network devices, IoT), endpoints (laptops, desktops, mobile devices), cloud environments (AWS, Azure, GCP configuration auditing), web applications (OWASP-aligned scanning), and containers (Docker image scanning, Kubernetes configuration). Scan frequency is configured based on asset criticality and compliance requirements—from continuous scanning for internet-facing systems to monthly scans for internal infrastructure. Results feed into a centralized vulnerability management platform that tracks findings from discovery through remediation and verification, providing complete lifecycle visibility for your security team and auditors.

Vulnerability Assessment Capabilities

Network Vulnerability Scanning
Comprehensive scanning of internal and external network infrastructure: servers, workstations, switches, routers, firewalls, wireless access points, printers, and IoT devices. We identify missing patches, insecure configurations, default credentials, exposed services, weak encryption protocols, certificate issues, and network segmentation gaps. Both authenticated and unauthenticated scans reveal different vulnerability classes—authenticated scans detect local vulnerabilities that remote scans miss, while unauthenticated scans identify the same attack surface an external adversary would discover.
Endpoint Security Assessment
Agent-based or agentless endpoint assessment evaluates operating system patch levels, application vulnerabilities, browser security configurations, endpoint protection status, disk encryption compliance, USB device policy enforcement, and local administrator account management. For organizations with remote workers, endpoint assessment extends to devices connecting from outside the corporate network. Results identify which endpoints are most vulnerable to compromise and which require immediate attention to prevent them from becoming attack entry points.
Cloud Configuration Auditing
Cloud environments (AWS, Azure, GCP) receive specialized assessment against CIS Benchmarks and cloud security best practices: IAM policy review, security group analysis, storage access controls, encryption configuration, logging completeness, network exposure evaluation, and container security posture. Cloud misconfigurations are now the leading cause of data breaches involving cloud infrastructure. Our assessments identify overly permissive policies, publicly accessible resources, and compliance gaps specific to your cloud platform.
Web Application Scanning
Automated web application scanning identifies common vulnerabilities across your web properties: SQL injection, cross-site scripting, security misconfigurations, sensitive data exposure, broken authentication, and known component vulnerabilities. Scans cover both public-facing websites and internal web applications. For deeper analysis of business logic and complex authentication flows, complement automated scanning with our web application penetration testing services.
Container & Kubernetes Security Scanning
Container image scanning identifies vulnerabilities in base images, application dependencies, and package managers before deployment. Kubernetes configuration assessment evaluates RBAC policies, network policies, pod security standards, secrets management, and cluster-level security settings. For organizations running containerized workloads, container security scanning catches vulnerabilities that traditional network scanners cannot detect—including vulnerabilities in application libraries that are only exploitable within the container context.
Compliance-Specific Scanning
Framework-specific scan policies evaluate your environment against compliance requirements: CMMC Level 1/2 security practices, HIPAA security rule technical safeguards, PCI DSS requirements (including ASV scanning for Requirement 11.2), SOC 2 Trust Services Criteria, and NIST 800-171 security controls. Reports map findings to specific compliance controls, providing auditors with evidence of your vulnerability management program's scope, frequency, and remediation effectiveness. Scan policies are updated as frameworks evolve to maintain compliance alignment.
Vulnerability Management Reporting
Monthly and quarterly reports track vulnerability trends, remediation velocity, mean time to remediate by severity, compliance posture changes, and emerging risk areas. Executive dashboards summarize security posture for leadership without technical detail overload. Technical reports provide your IT team with specific findings, remediation steps, and validation guidance. Trend analysis demonstrates security program improvement over time—essential evidence for compliance audits, board reporting, and cyber insurance applications.

Our Vulnerability Assessment Process

01

Asset Discovery & Scope Definition

We discover and inventory all assets across your environment: network devices, servers, endpoints, cloud resources, web applications, and IoT devices. Asset criticality is classified based on business function, data sensitivity, and exposure level. Scan schedules, authentication credentials, and exclusion windows are configured. The result is a comprehensive asset inventory that ensures nothing is missed during scanning.

02

Scanning & Analysis

Automated scans execute on scheduled intervals with results analyzed by our security engineers. False positives are validated and removed. True positives are scored using CVSS with contextual adjustments for asset criticality, exploit availability, and exposure level. Findings are deduplicated across scan sources and enriched with threat intelligence indicating whether vulnerabilities are being actively exploited in the wild.

03

Remediation Guidance & Support

Prioritized remediation reports provide your team with specific steps to address each vulnerability: patches to apply, configurations to change, services to disable, or compensating controls to implement when immediate remediation is not feasible. For managed service clients, we coordinate remediation scheduling, assist with patch deployment, and validate fixes through rescanning. Remediation tracking ensures findings move through the lifecycle from discovery to resolution.

04

Continuous Improvement

Monthly reporting tracks remediation progress, identifies recurring vulnerability patterns, and measures security posture improvement over time. Quarterly reviews assess scan coverage, adjust scanning policies for new assets and threats, and update risk scoring criteria. The vulnerability management program evolves with your environment, ensuring continuous protection rather than static point-in-time snapshots that become outdated within weeks of delivery.

Vulnerability Assessment FAQs

How often should vulnerability assessments be conducted?
Internet-facing systems should be scanned at least weekly. Internal infrastructure should be scanned at least monthly. PCI DSS requires quarterly ASV scans for external-facing systems. Many compliance frameworks recommend or imply continuous scanning. The optimal frequency depends on your risk tolerance, compliance requirements, and the rate of change in your environment. We configure scan schedules based on your specific needs, with more frequent scanning for higher-risk assets.
What is the difference between vulnerability assessment and penetration testing?
Vulnerability assessment identifies and catalogs known vulnerabilities across your entire environment using automated scanning tools. It provides breadth—finding thousands of potential issues. Penetration testing manually exploits specific vulnerabilities to prove real-world impact. It provides depth—demonstrating what an attacker could actually accomplish. Both are essential: assessments for continuous monitoring, pen tests for periodic validation. Our penetration testing services complement vulnerability assessment for complete security coverage.
Will vulnerability scanning affect our system performance?
Modern vulnerability scanners are designed for minimal performance impact. We configure scan intensity, concurrency limits, and scheduling to avoid affecting production systems during business hours. Scans targeting production systems run during off-peak hours when possible. Authenticated scans use dedicated service accounts with appropriate resource limits. If any scan causes observable performance degradation, we adjust parameters immediately. In practice, well-configured vulnerability scans operate without detectable impact on system performance.
How do you handle false positives?
False positive management is a core part of our service. Our security engineers validate high and critical findings before reporting, cross-referencing scan results with service configurations, patch levels, and compensating controls. Confirmed false positives are documented and excluded from future reports to prevent alert fatigue. Suspicious findings that cannot be remotely validated are flagged for investigation rather than either reported as confirmed or dismissed as false. This validation process ensures your team spends remediation effort on real vulnerabilities.
What compliance requirements does vulnerability assessment satisfy?
Vulnerability assessment addresses requirements in CMMC (RA.L2-3.11.2, RA.L2-3.11.3), HIPAA Security Rule risk analysis (164.308(a)(1)), PCI DSS Requirements 6.1 and 11.2, SOC 2 Common Criteria CC7.1, NIST 800-171 (3.11.2, 3.11.3), and NIST 800-53 (RA-5). Our reports map findings to specific controls within these frameworks, providing auditors with the evidence they need to validate your vulnerability management program. See our CMMC compliance page for framework-specific implementation details.
Do you provide PCI DSS ASV scanning?
Yes. We provide PCI DSS Approved Scanning Vendor (ASV) scanning through our scanning partners to satisfy Requirement 11.2. ASV scans are conducted quarterly against your external-facing cardholder data environment and produce PCI-compliant scan reports that your QSA or acquiring bank requires. ASV scanning integrates with our broader vulnerability assessment program, providing both PCI compliance evidence and comprehensive security visibility.
Can you scan our cloud environment?
Yes. We scan AWS, Azure, and GCP environments for configuration vulnerabilities, including IAM policy weaknesses, exposed storage, insecure networking, missing encryption, and logging gaps. Cloud assessments evaluate configurations against CIS Benchmarks for each cloud platform. We also scan cloud-hosted VMs, containers, and applications using the same methodologies applied to on-premise infrastructure. Results identify cloud-specific risks that traditional network scanners miss.
How much does vulnerability assessment cost?
Pricing depends on the number of assets (IP addresses, endpoints, cloud accounts), scan frequency, and service level (scan-and-report versus fully managed). We provide transparent monthly pricing that includes scanning tools, analysis, reporting, and remediation support without capital investment in scanning infrastructure. Most organizations find that managed vulnerability assessment costs less than purchasing, deploying, and staffing scanning tools internally—while delivering better analysis and compliance documentation.
