Cybersecurity Service Definitions: Clarifying Industry Terms

At Netragard, we believe cybersecurity must be rooted in precision—both in execution and in language. Misused or conflated service terms dilute risk assessments, weaken engagement outcomes, and often deceive buyers. Below is a comprehensive glossary of properly defined cybersecurity service offerings, based on best practices, operational distinctions, and modern threat landscapes.

Penetration Testing (Pen Test)

A Penetration Test is a structured, manual security assessment that simulates real-world attacks to exploit vulnerabilities in systems, networks, or applications. The goal is to demonstrate actual risk through safe exploitation and provide meaningful remediation guidance.

• Manual exploitation of real targets
• Custom attack chains and threat actor tactics
• Deliverable includes exploited vulnerabilities and business impact

Manual Penetration Test

A Manual Penetration Test is executed almost entirely by expert human testers without dependance on automated scanners for vulnerability discovery. This method uncovers complex logic flaws, chained vulnerabilities, and misconfigurations that automated tools consistently miss.

• High signal, zero false positives
• Real-world adversarial thinking
• Ideal for custom-built systems and sensitive assets

Industry Standard Penetration Test

An Industry Standard Penetration Test typically combines automated vulnerability scanning with limited manual validation by testers. It follows a checklist-driven methodology based on compliance or common frameworks (e.g., OWASP Top 10), often prioritizing breadth over depth. While useful for identifying common issues, it may miss complex attack chains, business logic flaws, or context-specific risks.

• Mixed signal, may contain false positives
• Checklist-oriented methodology
• Sufficient for basic compliance or recurring hygiene

Web Application Penetration Test

A Web Application Penetration Test is a targeted assessment of web-based software for vulnerabilities like SQL injection, cross-site scripting, broken authentication, insecure APIs, and logic flaws.

• Based on and expands beyond OWASP Top 10
• Includes exploitation of flaws in authentication, authorization, and business logic
• Critical for SaaS platforms, portals, and public-facing apps

External Infrastructure Penetration Test

An External Infrastructure Penetration Test simulates an attack from outside the organization, targeting public-facing assets like websites, VPNs, mail servers, and exposed services.

• Evaluates perimeter defenses
• Tests firewall configurations, exposed services, DNS, SSL, and more
• Demonstrates how an anonymous attacker could breach your edge

Internal Infrastructure Penetration Test

An Internal Infrastructure Penetration Test simulates an attacker who has already gained access to your internal network—either as a malicious insider or via a compromised endpoint.

• Focuses on privilege escalation, lateral movement, and AD exploitation
• Tests segmentation, workstation hygiene, GPO misconfigurations
• Assesses post-breach risk and response preparedness

Red Team Engagement (Ruby Red)

A Red Team Engagement is a covert, full-scope adversary simulation targeting people, processes, and technology. It is designed to test your organization’s ability to detect and respond to sophisticated, real-world attack scenarios.

• Objective-based (e.g., domain compromise, data exfiltration)
• Multi-vector: phishing, physical intrusion, malware, etc.
• Emulates nation-state or APT behavior

Purple Team Engagement

A Purple Team Engagement is a collaborative exercise where offensive testers (Red Team) and defenders (Blue Team) work together in real time to improve threat detection, alerting, and response.

• Maximizes learning and tuning of defensive tools
• Validates SIEM rules, EDR alerts, and SOC workflows
• Bridges the gap between offense and defense

Penetration Testing as a Service (PTaaS)

PTaaS is a cloud-based penetration testing delivery model that combines automated scanning with human testing and real-time dashboards. Some platforms may include AI triage or DevSecOps integration.

• Flexible and scalable
• Enables continuous testing models
• Must include human analysis to be effective

Vulnerability Scan

A Vulnerability Scan is an automated process that identifies known vulnerabilities in software, systems, or configurations. It does not include manual verification, exploitation, or impact analysis.

• Quick and broad coverage
• Good for recurring security hygiene
• Not a penetration test—no exploitation occurs

Vulnerability Assessment

A Vulnerability Assessment is a more thorough process that builds on vulnerability scanning by incorporating manual validation and risk prioritization.

• May include some analyst review
• Focuses on breadth and severity scoring (CVSS)
• Useful for patch management and compliance

Cloud Security Assessment

A Cloud Security Assessment analyzes cloud environments (e.g., AWS, Azure, GCP) for misconfigurations, weak permissions, exposed data, and insecure default settings.

• Assesses IAM roles, S3 buckets, VPCs, container security, etc.
• Tests for compliance with cloud best practices and frameworks
• Critical for hybrid and cloud-native architectures

Security Audit

A Security Audit is a formal review of an organization’s security controls, policies, and practices against recognized standards like NIST, ISO 27001, HIPAA, or PCI DSS.

• Documentation-focused and checklist-driven
• Does not include exploitation or live testing
• Often required for regulatory or contractual compliance

Blue Team Operations

A Blue Team is responsible for ongoing detection, response, and protection of an organization’s assets. Blue Team operations include log monitoring, threat hunting, incident response, and forensic analysis.

• Utilizes SIEM, EDR, IDS/IPS, and threat intel
• Focus is on defense, containment, and recovery
• Works in parallel or opposition to Red Team engagements

Key Differences Between Similar Services

Key Difference Between Manual and Industry Standard Penetration Testing:

• A Manual Penetration Test is a deep, adversary-simulated process conducted almost entirely by expert human testers. It identifies and exploits vulnerabilities without reliance on automated scanners, uncovering complex logic flaws, chained attacks, and misconfigurations that scanners consistently miss. Every finding is verified, resulting in high signal and zero false positives.
• An Industry Standard Penetration Test relies heavily on automated scanning, with limited manual validation. While it may satisfy compliance requirements and catch common issues, it often misses context-specific risks and nuanced attack paths. These tests tend to produce more false positives and lack the depth of true threat simulation.

In short:

• Manual Penetration Testing simulates real-world adversaries.
• Industry Standard Penetration Testing checks boxes.

Key Difference Between Simulation & Emulation in Cybersecurity:

• Simulation often involves generalized representations of attacker behavior (e.g., a red team using various techniques to achieve goals).
• Emulation aims to exactly reproduce the steps of a known threat actor (e.g., emulating APT29’s tactics step-by-step).

Key Difference Between Assessment & Test in Cybersecurity:

• A Test is an active process that challenges systems, defenses, or controls—typically by simulating real-world attacks to observe how the target responds under pressure. It is designed to exploit vulnerabilities and demonstrate practical risk.
• An Assessment is a passive or evaluative process that reviews configurations, policies, or known vulnerabilities without necessarily interacting with the environment in an adversarial way. It identifies potential issues without proving exploitability.

In short:

Tests demonstrate impact. Assessments identify potential.
