What Is Penetration Testing?
Penetration testing is a controlled security assessment that simulates attacker techniques to identify weaknesses and validate exploitability across your systems, networks, and applications.
Unlike vulnerability scanning, which identifies potential issues, penetration testing safely demonstrates which vulnerabilities can be exploited, how far an attacker could move, and what data or systems could be compromised. This distinction is critical for regulated organizations because examiners often expect defensible evidence of risk, not just technical scan results.

Why Choose SBS for Your Penetration Test?
Our penetration testing methodology combines proven frameworks with decades of experience supporting regulated organizations. Every engagement follows a structured approach that prioritizes safety, clarity, and meaningful outcomes without disrupting business operations. Our penetration tests are:
Types of Penetration Testing We Offer
- External Network Penetration Testing
- Internal Network Penetration Testing
- Web Application Penetration Testing
- Wireless Penetration Testing
- PCI DSS Penetration Testing
External penetration testing evaluates the security of your internet‑facing systems from the perspective of an outside attacker. This testing identifies vulnerabilities and misconfigurations that could allow unauthorized access to your network. Common focus areas include:
- Public‑facing IP addresses and services
- Firewall and perimeter defenses
- Exposure to known exploits and misconfigurations
External penetration testing is frequently required by regulatory frameworks and provides critical insight into your organization's external attack surface.
Internal penetration testing simulates an attacker who has already gained access to your internal network — through compromised credentials, phishing, or a rogue device.
This testing evaluates:
- Lateral movement opportunities
- Privilege escalation paths
- Active Directory and authentication weaknesses
- Segmentation and internal controls
Internal penetration testing helps organizations understand the potential impact of an assumed breach and is increasingly emphasized by examiners.
Web application penetration testing assesses the security of public‑facing and internal applications, including portals, APIs, and business‑critical systems. Testing focuses on vulnerabilities such as:
- Injection attacks (SQL, command injection)
- Cross‑site scripting (XSS)
- Authentication and authorization flaws
- Insecure configurations and data exposure
Web applications are often a primary attack vector, making this testing essential for protecting sensitive data and customer information.
Wireless penetration testing evaluates the configuration and security of your wireless networks, whether used internally or available to guests. This testing identifies:
- Weak encryption or authentication
- Improper segmentation
- Unauthorized access points
- Pivot opportunities into the internal network
Wireless networks are frequently overlooked but can provide attackers with a direct path into your environment if improperly secured.
Organizations that process, store, or transmit payment card data are required to perform PCI DSS penetration testing. SBS provides PCI DSS penetration testing that:
- Meets PCI DSS Requirement 11
- Validates segmentation controls
- Produces documentation suitable for QSAs and auditors
Our testing helps ensure payment systems are protected while supporting ongoing compliance efforts.
