Real Attack Simulation

Our penetration testers use the same tools, techniques, and procedures that actual attackers employ—including OSINT reconnaissance, credential harvesting, privilege escalation, lateral movement, and data exfiltration. Automated scanners find known vulnerabilities; our testers find the attack paths that chain vulnerabilities into actual breaches.

Actionable Reporting

Every finding includes technical evidence, business impact assessment, exploitation proof, and step-by-step remediation guidance. Executive summaries communicate risk to leadership without technical jargon. Technical appendices give your engineering team everything they need to fix issues without guesswork.

Compliance-Ready Deliverables

Our penetration testing reports satisfy CMMC, HIPAA, PCI DSS, SOC 2, and NIST 800-171 assessment requirements. Reports map findings to specific compliance controls, providing auditors with the evidence they need and giving your compliance team clear remediation priorities.

23+ Years of Experience

Petronella Technology Group, Inc. has provided cybersecurity services since 2002—penetration testing, vulnerability assessment, incident response, and security architecture. Our engineers have tested networks, applications, and infrastructure across healthcare, defense, financial services, manufacturing, and government sectors.

Why Penetration Testing Is Not Optional

Scanners Find Vulnerabilities — Pen Tests Prove Exploitability
The gap between vulnerability scanning and penetration testing is the gap between finding theoretical weaknesses and proving actual exploitability. Vulnerability scanners identify known CVEs, misconfigurations, and outdated software versions. They generate lists of findings ranked by generic severity scores. But they cannot determine whether a medium-severity SQL injection vulnerability on your customer portal chains with a low-severity file upload issue to enable complete database extraction. They cannot test whether your incident response team detects lateral movement through Active Directory. They cannot evaluate whether your network segmentation actually prevents an attacker who compromises a workstation from reaching financial systems. Penetration testing answers these questions through controlled exploitation—proving what an actual attacker could accomplish against your specific environment.
Real Attackers Chain Vulnerabilities — So Do We
Modern threat actors do not follow vulnerability scanner output. They perform reconnaissance, identify attack surfaces, test for business logic flaws that scanners cannot detect, chain low-severity vulnerabilities into high-impact attack paths, and use social engineering to bypass technical controls entirely. A penetration test simulates this methodology: our engineers think like attackers, plan attack strategies against your specific architecture, and execute controlled exploitation that reveals not just vulnerabilities but the realistic impact of their exploitation on your business operations, data, and compliance posture.
Compliance Frameworks Mandate Penetration Testing
For organizations subject to compliance requirements, penetration testing is explicitly mandated or strongly implied by virtually every security framework. CMMC Level 2 requires security assessment activities that include penetration testing concepts. HIPAA security rule risk analysis should include penetration testing as a mechanism to evaluate safeguard effectiveness. PCI DSS Requirement 11.4 mandates both internal and external penetration testing at least annually and after significant changes. SOC 2 Trust Services Criteria include testing the effectiveness of controls through simulated attacks. NIST SP 800-53 CA-8 specifically requires penetration testing as a security assessment technique. Our penetration testing reports map findings directly to these framework requirements, providing compliance evidence that satisfies auditors.
Industry-Standard Methodology With Manual Depth
Petronella Technology Group, Inc.'s penetration testing methodology combines automated tooling for efficiency with manual testing for depth. We follow OWASP Testing Guide for web application assessments, PTES (Penetration Testing Execution Standard) for network and infrastructure testing, and NIST SP 800-115 Technical Guide to Information Security Testing and Assessment for methodology framework alignment. Our Raleigh, North Carolina-based security engineers have tested environments ranging from small business networks to enterprise architectures spanning multiple sites and cloud environments—delivering findings that range from critical remote code execution vulnerabilities to subtle business logic flaws that automated tools categorically miss.

Penetration Testing Capabilities

External Network Penetration Testing
We test your internet-facing attack surface from an external attacker's perspective: public IP ranges, DNS configurations, email security (SPF/DKIM/DMARC), VPN endpoints, web applications, exposed services, SSL/TLS configurations, and cloud resource exposure. Testing includes OSINT reconnaissance to identify information leakage that attackers use for targeting, followed by systematic vulnerability identification and controlled exploitation. Findings reveal what an external attacker could access without insider knowledge or credentials.
Internal Network Penetration Testing
Simulating an attacker who has gained initial access—through phishing, physical access, or compromised credentials—we test internal network segmentation, Active Directory security, privilege escalation paths, lateral movement opportunities, and access to sensitive data stores. Testing includes password spraying against discovered accounts, Kerberos attack techniques (Kerberoasting, AS-REP Roasting), LLMNR/NBT-NS poisoning, SMB relay attacks, and domain privilege escalation. Results reveal how far an insider threat or post-compromise attacker could penetrate your environment.
Web Application Penetration Testing
Following OWASP Testing Guide methodology, we assess web applications for injection vulnerabilities (SQL, NoSQL, LDAP, OS command), authentication and session management flaws, cross-site scripting (XSS), insecure direct object references, security misconfiguration, sensitive data exposure, cross-site request forgery (CSRF), server-side request forgery (SSRF), and business logic vulnerabilities specific to your application. Testing covers both authenticated and unauthenticated scenarios across all user roles. API endpoints receive dedicated testing for authentication bypass, rate limiting, and data exposure.
Wireless Network Penetration Testing
On-site wireless assessments evaluate your Wi-Fi security posture: encryption strength, authentication mechanisms (WPA2-Enterprise, WPA3), rogue access point detection, evil twin attack susceptibility, guest network isolation effectiveness, and wireless client security. We test whether wireless access provides a path to internal network resources that bypasses perimeter security controls. For organizations in the Raleigh-Durham area, we conduct on-site wireless assessments at your facilities.
Social Engineering Assessment
Phishing simulations, pretexting calls, and physical social engineering attempts test your organization's human security layer. We craft realistic phishing campaigns using intelligence gathered during reconnaissance, measure click rates and credential submission rates, and evaluate whether security awareness training is translating into behavioral change. Results identify which departments or roles are most susceptible and inform targeted training improvements. Social engineering testing proves whether your technical controls matter when an attacker bypasses them through human interaction.
Cloud Environment Penetration Testing
Cloud-specific testing evaluates AWS, Azure, and GCP configurations for IAM policy weaknesses, overly permissive security groups, exposed storage buckets, serverless function vulnerabilities, container escape paths, and cross-account access risks. We test cloud-specific attack techniques including metadata service exploitation, role chaining, and service-to-service authentication bypass. Testing follows cloud provider-approved methodologies and stays within authorized scope boundaries. Results map to CIS Benchmarks for your specific cloud platform.
Physical Security Assessment
Physical penetration testing evaluates badge systems, door locks, tailgating prevention, visitor management, server room access controls, and the ability to plant rogue devices on your network through physical access. For organizations where physical security is a compliance requirement (CMMC, data center standards), these assessments prove that physical controls function as documented. Testing is conducted discreetly with appropriate authorization and coordination to avoid disrupting normal business operations.

Our Penetration Testing Process

01

Scoping & Rules of Engagement

We define the testing scope, objectives, methodology, timelines, communication protocols, and rules of engagement with your team. Scope includes target systems, testing types (black box, gray box, white box), exclusions, and authorized testing windows. Rules of engagement document escalation procedures, emergency contacts, and handling of critical findings discovered during testing. Both parties sign off before testing begins.

02

Reconnaissance & Discovery

OSINT gathering identifies publicly available information about your organization: employee names, email formats, technology stack indicators, leaked credentials, domain registrations, and infrastructure exposure. Active scanning discovers live hosts, open ports, running services, and version information within the authorized scope. This reconnaissance phase mirrors an attacker's pre-attack intelligence gathering and often reveals information exposure that creates attack opportunities.

03

Exploitation & Post-Exploitation

Identified vulnerabilities are exploited under controlled conditions to demonstrate real-world impact. Post-exploitation activities include privilege escalation, lateral movement, persistence establishment, and data access validation—proving what an actual attacker could accomplish after initial compromise. Every exploitation step is documented with screenshots, command output, and timestamps. Critical findings are reported immediately rather than waiting for the final report.

04

Reporting & Remediation Support

Comprehensive reporting includes an executive summary for leadership, detailed technical findings with exploitation evidence, risk ratings using CVSS scoring, and prioritized remediation guidance for each finding. We present findings to both technical and executive audiences, answer questions, and provide remediation support during your fix cycle. Optional retesting validates that remediation efforts successfully address identified vulnerabilities.

Why Choose Petronella Technology Group, Inc. for Penetration Testing

23+ Years of Cybersecurity

Petronella Technology Group, Inc. has provided cybersecurity services since 2002. Our penetration testers combine decades of offensive security experience with deep knowledge of compliance frameworks, industry-specific threats, and real-world attack patterns that affect organizations in healthcare, defense, financial services, and government sectors.

Beyond Automated Scanning

Automated scanners are part of our toolkit, not the entirety of our testing. Our engineers manually test business logic, chain vulnerabilities, attempt privilege escalation, and simulate real attacker behavior that no scanner can replicate. The difference between our findings and scanner output is the difference between a vulnerability list and an actual security assessment.

Compliance-Mapped Reporting

Our reports map findings to CMMC, HIPAA, PCI DSS, SOC 2, NIST 800-171, and other framework requirements. Auditors receive the evidence format they expect. Compliance teams receive clear remediation priorities. Leadership receives business-impact assessments that justify security investment without requiring technical interpretation.

Remediation Guidance

Findings without remediation guidance are academic exercises. Every vulnerability in our reports includes specific, actionable steps to fix the issue—including configuration changes, code modifications, architecture recommendations, and compensating controls when immediate remediation is not feasible. We provide remediation support during your fix cycle and retesting after remediation.

Immediate Critical Notification

Critical vulnerabilities—remote code execution, authentication bypass, data exposure—are reported immediately upon discovery, not held for the final report. You receive a phone call and encrypted notification within hours so your team can begin remediation while testing continues on other targets. This responsible disclosure practice reflects our commitment to your security, not just our testing schedule.

Ongoing Security Partnership

Penetration testing is most effective as part of a continuous security program. Our vulnerability assessment services provide ongoing security scanning between annual penetration tests, and our cybersecurity services address findings with remediation implementation, security architecture improvements, and compliance program management.

Penetration Testing FAQs

How often should we conduct penetration testing?
At minimum, annually and after significant infrastructure changes (network redesigns, major application deployments, cloud migrations, mergers). PCI DSS requires at least annual testing plus after significant changes. Many organizations conduct quarterly external tests and semi-annual internal tests. High-risk environments benefit from continuous testing programs. Between penetration tests, regular vulnerability assessments maintain security visibility.
What is the difference between a vulnerability scan and a penetration test?
Vulnerability scans use automated tools to identify known vulnerabilities against a database of signatures. They produce lists of potential issues but do not verify exploitability. Penetration testing uses both automated tools and manual techniques to actually exploit vulnerabilities, chain findings together, and demonstrate real-world impact. A scanner might identify a potential SQL injection; a penetration tester extracts your database to prove the impact. Both are valuable—scans for breadth, pen tests for depth.
Will penetration testing disrupt our business operations?
Professional penetration testing is designed to minimize business impact. Rules of engagement define testing windows, excluded systems, and escalation procedures. Denial-of-service testing is optional and scheduled during maintenance windows if included. Our testers monitor for unintended impact during testing and halt immediately if disruption occurs. In practice, well-scoped penetration tests operate without detectable impact on normal business operations. We coordinate closely with your IT team throughout the engagement.
What do we receive when the penetration test is complete?
You receive a comprehensive report containing: executive summary with business-impact assessment, detailed technical findings with exploitation evidence (screenshots, command output, data samples), CVSS risk ratings for each finding, compliance framework mapping, prioritized remediation guidance with specific steps, and an appendix documenting methodology and tools used. We also deliver a presentation to your technical and executive teams, providing context, answering questions, and offering remediation support.
How much does penetration testing cost?
Penetration testing costs depend on scope: number of IP addresses, applications, testing types, compliance requirements, and engagement duration. We provide transparent pricing after a scoping call where we understand your environment and objectives. The cost of a penetration test is always a fraction of the cost of a breach—IBM's 2025 Cost of a Data Breach Report puts the average breach cost at $4.88 million. Identifying and fixing vulnerabilities before attackers exploit them is the most cost-effective security investment available.
Do you offer retesting after we fix vulnerabilities?
Yes. We include targeted retesting as part of our engagement to validate that critical and high-severity findings have been successfully remediated. Retesting confirms that fixes address the root cause rather than just masking symptoms, and provides updated evidence for compliance documentation. For organizations on managed security engagements, retesting is included as part of the ongoing service.
Which compliance frameworks require penetration testing?
PCI DSS Requirement 11.4 explicitly mandates annual penetration testing. CMMC Level 2 requires security assessment activities that include penetration testing methodologies. HIPAA security rule risk analysis should include penetration testing to evaluate safeguard effectiveness. SOC 2 Trust Services Criteria expect testing of control effectiveness. NIST SP 800-53 CA-8 requires penetration testing. Even where not explicitly mandated, penetration testing is considered a security best practice by every major framework and is expected by auditors as evidence of security program maturity. See our CMMC compliance and HIPAA security guide for framework-specific details.
What is the difference between black box, gray box, and white box testing?
Black box testing provides the tester with no prior knowledge—simulating an external attacker starting from scratch. Gray box testing provides limited information (network diagrams, user credentials, application documentation)—simulating an attacker who has gained some insider knowledge. White box testing provides full access to source code, architecture documents, and system configurations—enabling the deepest possible assessment. Most organizations benefit from gray box testing, which balances realistic attack simulation with efficient use of testing time. We recommend the approach that best matches your security objectives and compliance requirements.
