Penetration testing simulates attacks against an organization’s systems, often involving human actors who emulate real-world attackers. Pen testers search for vulnerabilities in specific applications or systems and perform deep dives, sometimes chaining vulnerabilities together to achieve a particular goal. This approach provides focused and in-depth analysis of security posture. Source
DAST is a black-box testing methodology for assessing application security. It identifies vulnerabilities in running applications by sending various malicious or unusual inputs and observing responses. DAST is typically automated, integrated into CI/CD pipelines, and focuses on applications and APIs, providing a balance between depth and breadth of analysis. Source
ASM maintains visibility into an organization’s digital attack surface and its vulnerabilities. ASM solutions continuously inventory assets, detect vulnerabilities in known assets, and help security teams prioritize remediation. ASM provides broad, surface-level security testing focused on external-facing IT assets, including shadow IT. Source
Pen testing provides the most focused and in-depth analysis, targeting specific systems. DAST offers a balance between depth and breadth, focusing on applications and APIs. ASM provides the broadest but shallowest coverage, mapping and tracking the entire digital attack surface. Source
Pen testing typically focuses on specific internal and external systems. DAST is commonly used for applications and APIs, often during development. ASM primarily monitors external-facing IT assets, including official corporate systems and shadow IT. Source
Pen testing has a low false positive rate because human testers validate vulnerabilities. DAST has a high false positive rate due to automation and limited exploitation. ASM also has a low false positive rate, as vulnerabilities are validated before being reported and prioritized. Source

Penetration testing, dynamic application security testing (DAST), and attack surface management (ASM) are all strategies designed to manage an organization’s digital attack surface. However, while each aids in identifying and closing vulnerabilities, they have significant differences and play complementary roles within a corporate cybersecurity strategy.
Let’s take a quick look at the definition of each of these strategies:
Pen testing, DAST, and ASM are all geared toward reducing the number and severity of vulnerabilities in an organization’s digital attack surface. However, the three approaches also have significant differences.
One of the biggest differences between pen testing, DAST, and ASM is the scope and depth of the analysis that they provide:
The three technologies also differ significantly in the assets that they monitor:
When looking for vulnerabilities, there is the potential for false positives where a vulnerability that appears to exist based on surface analysis is not actually exploitable by an attacker. Pen testing, DAST, and ASM have different false positive rates:
Security testing is most effective if it is performed frequently and as early as possible within the lifecycle of an asset. Key differences in rates of occurrence and ownership of these types of assessments include:
| Pen testing | DAST | ASM | |
| Automation | Low | High | Medium |
| Analytic depth | High | Low | Low |
| Test frequency | Low | High | Very high (continuous) |
| Cost | High | Low | Low |
| Required expertise | High | Low | Low |
| Scope | Specific systems | Applications and APIs | External attack surface |
| Vulnerability exploitation | Yes | Rarely | No |
| False positives | Low | High | Low |
| Customizability | High | Low | Medium |
ASM differs significantly from DAST and pen testing in various ways, but all three are focused on reducing the number and severity of vulnerabilities in an organization’s IT environment. These different approaches to a shared purpose mean that ASM can complement pen testing and DAST in a few ways.
Pen testing provides the most in-depth analysis of an organization’s security posture and the lowest false positive rate. However, it is time and resource-intensive and usually focuses on a specific asset or set of systems.
External ASM (EASM) provides insight into where pen testing efforts can be focused to maximize return on investment. ASM maintains a complete inventory of the organization’s digital attack surface and known vulnerabilities in it. Based on this information, an organization can define the scope of a pen test to assess the security of high-value assets or perform a deep dive into the security of an asset that seems particularly vulnerable to exploitation.
Pen testing provides the deepest insight into potential vulnerabilities since human experts explore and exploit identified vulnerabilities. However, the time and cost associated with it means that organizations can only perform these assessments on an irregular basis.
EASM can fill the gap between pen tests and provide continuity across assessments. With broad visibility across an organization’s digital attack surface, ASM can identify and prioritize the vulnerabilities that an attacker is most likely to exploit to gain access to an organization’s environment. This protects against external threats and complements pen testing engagements, which help to manage the risk of attackers who have already achieved a foothold in an organization’s systems.
DAST solutions provide an assessment of an application or API’s security after each change to the codebase, enabling vulnerability detection and remediation with minimal technical debt. However, the effectiveness of this automated testing depends on the set of inputs that a DAST solution uses to evaluate the application under test.
ASM can help enhance the effectiveness of DAST by providing additional insight into an application’s eventual deployment environment and digital supply chain. With insight into the other applications that software will interact with — and their vulnerability to exploitation — DAST solutions can be tuned to enhance the realism and utility of their test cases.
In addition to enhancing an organization’s security, ASM also provides opportunities for cost savings, such as:
