SOC 2 Type II penetration testing scope in 2026 focuses on verifying whether security controls protecting customer data and critical systems are actively tested for vulnerabilities. Organizations that are being audited by SOC 2 Type II auditors will be required to prove that they have a system that is being tested on a regular basis in the form of structured security testing, which includes penetration testing and vulnerability tests.
The scope of SOC 2 security testing in the United States has been changing, with SOC 2 auditors anticipating organizations, especially in SaaS, to incorporate infrastructure, applications, APIs, and identity systems into the SOC 2 security testing. The tests are used to reveal the weak areas that might be used to permit unauthorized access, data breach, or service disruption that may be subject to SOC 2 Trust Services Criteria.
Since Type II assesses the effectiveness of controls over a period of time, the penetration testing is significant to support the audit process provided by SOC 2 Type II. The guide describes the SOC 2 penetration testing requirements, the environments that should be covered by the testing scope and how organizations can prepare security testing evidence to be used during the SOC 2 audits in 2026.

What Is SOC 2 Type II and Why Security Testing Matters
The SOC 2 Type II is an audit framework designed by the American Institute of Certified Public Accountants (AICPA) in order to assess the protection of customer information and secure operations of organizations. In contrast to point-in-time assessments, the Type II report looks into the consistency of findings of security controls over a long period of observation.
The firms seeking SOC 2 Type II compliance have to prove that their internal controls operate effectively within systems managing sensitive information. These involve the review of the access management, monitoring the systems, and whether there are safeguards that may identify the weaknesses that attackers may exploit.
Security testing assists in ensuring that these controls are working as it is expected. In case penetration testing finds any vulnerabilities, the organizations can fix those vulnerabilities and prove to the auditors that their security practices are actively involved in supporting the Trust Services Criteria applied to SOC 2 assessments.
| SOC 2 Type | What It Evaluates |
| Type I | Design of security controls at a specific point in time |
| Type II | Operational effectiveness of controls over a defined monitoring period |
Since the SOC 2 Type II is about the operations of the controls in practice, organizations have to demonstrate that they practice their security monitoring and testing processes during the entire audit period.
SOC 2 Type II Penetration Testing Scope in 2026
The 2026 type II penetration testing scope of the SOC 2 audit is determined based on the system boundary that was established in the SOC 2 audit process. This boundary determines the infrastructure, applications and services used in the storage, processing or transmission of customer data.
The penetration testing should target those components that have a direct impact on the security of that environment. When a system is involved in any of authentication, application access, data storage, or service delivery, it is usually within the testing scope since vulnerabilities of those systems may have an impact on the entire security posture examined during the audit.
Organizations that are about to organize SOC 2 audits should make sure that the testing scope is based on the actual architecture of their technology environment and not done on a limited set of systems. Running tests on just applications that are publicly facing and not on internal infrastructure or supporting services could leave areas that are of critical concern untested.
Systems Typically Included in SOC 2 Security Testing Scope
The SOC 2 security testing scope commonly includes:
- External network infrastructure that supports production systems (public-facing servers, gateways, and other internet-accessible services) may allow an unauthorized access attempt to compromise the environment.
- Internal networks that are linked to production settings, like systems that allow administrative access, back-end communication or internal service traffic, can have an impact on the security of customer data.
- Web applications consumed by customers or by an administrator, particularly portals, dashboards and interfaces in which vulnerabilities by means of authentication, authorization or input processing might give rise to audit issues.
- Application programming interfaces (APIs) utilized in service integration: APIs tend to process sensitive transactions, customer data exchange and machine-to-machine communication throughout the platform.
- Authentication (identity providers and access management services): Due to the possible direct impact of the effectiveness of the control, due to the possibility of vulnerabilities in the flow of logs, session controls, or privilege enforcement.
- Components of cloud infrastructure, like compute instances, containers, storage services, and security groups, usually belong to the production boundary and potentially expose it to misconfiguration or being misconfigured.
Testing these areas assists organizations to discover weaknesses that might interfere with the integrity of the systems or data protection within the scope of the SOC 2 audit.

SOC 2 Penetration Testing Requirements
Although SOC 2 does not specify a particular set of testing controls, it is a requirement to show that security controls that safeguard systems within the audit scope are being actively assessed. The requirements of SOC 2 penetration testing are thus bound to the Trust Services Criteria, in particular, the principle of security, according to which organizations are supposed to identify weaknesses and confirm that their protective measures are functioning well.
Penetration testing is commonly adopted in the simulation of real-world attack methods and to establish whether the systems have any weaknesses that could enable unauthorized access or even data disclosure. The findings assist organizations in knowing the performance of their technical controls in adverse situations.
External Infrastructure Testing
External infrastructure testing is dedicated to the systems that are available online. Attackers tend to attack these systems as the first point of entry most of the time.
Testing may include:
- Public-facing web servers and applications that attackers can access directly from the internet and can use as the first way into the environment.
- Exposed network services, including open ports, remote access services, or management interfaces, can expose a deficiency in hardening or access control.
- Cloud-based infrastructure that is linked to customer-facing systems, where insecure settings or poor segmentation may increase the external attack surface.
- Publicly available APIs, which are used by mobile applications, integrations, or customer workflows, might expose unsafe endpoints, weak authentication or information leakages.
The aim is to find out areas of weakness that may enable attackers to have unauthorized access to systems that support customer-facing services.
Internal Network Testing
Internal testing is used to assess the behavior of systems in the event that they get a foothold within the network. This situation aids organizations in knowing the effectiveness of internal segmentation and access limitation in deterring horizontal flow in the future.
Activities that could be tested include:
- Internal service exposure to find out whether any unnecessary services, management tools, or administrative interfaces can be accessed within the environment.
- Privilege escalation paths may enable a low-level internal foothold to expand into broader administrative access to systems or services.
- Network segmentation effectiveness to determine whether sensitive environments are appropriately segregated from the other lower-trust zones or generic internal access paths.
- Shared credentials, weak privilege boundaries, or insecure access control may be applied to audit-relevant systems.
Application Security Testing
Software platform vulnerabilities are targeted by application-level penetration testing. Since most SOC 2 settings have SaaS applications, application security testing is significant in the assessment of the implementation of user interactions, session management, and access controls.
Testing usually tests the following areas:
- The logic of authentication, such as the presence of login processes, passwords and authorizations, acts appropriately under various circumstances.
- Control Authorization controls, particularly allowing users to access resources, records, or functions other than those to which they are supposed to have permission.
- Input validation is essential in detecting any risk related to injection, unsafe handling of requests and insecure processing of the data provided by the user.
- Session management, such as session expiry, token management, cookies protection, and logout functionality, influences the security of the account.
- Data access controls, to ensure that application logic does not expose or retrieve customer or tenant data illegally.
These assessments are used to ensure that application behavior is in line with the security controls considered in SOC 2 audits.
SaaS SOC 2 Pentesting Considerations
The architectural risks of SaaS environments are peculiar and should be taken into account to establish the SOC 2 penetration testing scope. Since SaaS platforms are generally provided in the form of web applications, APIs and cloud infrastructure, testing should address the interaction of these components and whether security measures can be used to ensure unauthorized access across tenants and services.
As opposed to the traditional on-premise systems, SaaS applications sometimes have a multi-tenant setup whereby there are several customers sharing the same infrastructure. In this architecture, tests must be done to ensure that the data or services of one tenant cannot be accessed by another tenant.
SaaS Attack Surface Areas
Security testing for SaaS platforms commonly includes:
Customer-facing web applications have vulnerable end-user security that may be compromised by insecure forms, broken access control or broken session flaws.
- API endpoints that are utilized to integrate sensitive functions, poor authentication, and too much data access, unless they are adequately secured.
- Administrative portals and management portals, which may include more privileged functionality and thus need to have increased validation of stronger access.
- Authentication services like SSO systems are central control points for identity and access within the platform.
The online services that provide application functionality, and where the insecure internal logic, service exposure or weak controls on communication can impact platform integrity.

Multi-Tenant Architecture Risks
The providers of SaaS also have to ensure that the mechanisms of separating data within tenants are operating effectively. Some of the tests can include the checking of access controls, handling of sessions and permission of the backend services so that data belonging to one organization cannot be used by the other.
These assessments are especially significant to SaaS vendors who are about to undergo SOC 2 audit penetration testing because, frequently, auditors will look into the response of the application security controls to safeguard the environment of the customer in a shared infrastructure.

How SOC 2 Audit Penetration Testing Is Evaluated
In a SOC 2 Type II audit, penetration testing is not the type of testing that is evaluated by just setting up a test has been conducted. Auditors assess the suitability of the testing program and its organization, the scope and supporting measures of the test program. The aim is to understand how the organization utilizes the results of testing to enhance its security position in the long run.
The auditors would usually go through documentation that would show how the vulnerabilities were detected, monitored, and patched in the systems that are within the scope of the SOC 2 audit.
Evidence Auditors Typically Review
Organizations undergoing SOC 2 audit penetration testing should be prepared to provide:
- The latest report of penetration testing, and what was tested, what was the method, and what were the findings?
- A well-defined testing scope, which indicated that the evaluation included systems that fell within the SOC 2 audit scope and not an environment that was dissimilar or incomplete.
- The list of vulnerabilities found during testing, with the severity level and sufficient detail to indicate that some review of findings was not done in a meaningless way.
- Remediation strategies concerning the identified problems, how the organization reacted to the findings and allocated corrective action.
- Assurance that material results have been addressed, particularly with those issues of greater risk that might lead to impairment of the perception of the auditor with regard to the effectiveness of the controls.
- Repetition of an outcome test or validation reports with the demonstration that not only were fixes planned, but also checked after execution.
Such documentation should be provided to show that security testing is not a one-time exercise, but an ongoing risk management process.
Alignment With the SOC 2 System Boundary
The auditors also ensure that the scope of penetration testing is in line with the systems contained in the SOC 2 report. When critical systems or infrastructure components are not tested, the auditors can wonder why the security evaluation is not a complete reflection of the audited environment.
It is important to ensure that the testing scope is equivalent to the SOC 2 system boundary in order to have a more complete picture regarding the level of security assessment in the audit process.
Common Mistakes in SOC 2 Penetration Testing Scope
Organizations that are about to undergo SOC 2 audits occasionally restrict penetration testing to a limited section of their environment. Under the circumstances when the scope of the testing is not a reflection of the systems that are covered within the audit boundary, the weaknesses that are significant can go undetected, and the auditors can be interested in the question of whether the security testing can offer any meaningful coverage.
These are some of the common pitfalls that organisations should avoid when trying to determine the scope of their SOC 2 security testing to make sure that the systems are tested by the auditors.
Testing Only Public-Facing Applications
Other organizations do not care about internal infrastructure and supporting services, and only concentrate on external web applications. Nevertheless, internal networks, administration systems and back-end services can also influence the security of the customer information, and it should be taken into account during testing.
Excluding Cloud Infrastructure
Production systems of SaaS platforms are frequently placed in a critical environment in the cloud. In case the penetration testing does not cover cloud settings, access controls, or network design, the organizations can ignore the vulnerabilities which impact the functioning of the systems in the cloud.
Limited API Security Testing
The contemporary subscriptions service (SaaS) tools heavily depend on APIs to be integrated and communicate with each other. Inability to test APIs may create loopholes when it comes to the evaluation of authentication logic, authorization controls, and data access mechanisms.
Incomplete Vulnerability Remediation
Findings in penetration testing are supposed to be dealt with by using remediation measures. Organizations may not get all of the vulnerable areas that have been identified fixed, or they may not retest fixes after fixing them, thus leaving unsecured vulnerabilities in the environment.
Poor Documentation of Testing Activities
SOC 2 auditors would demand that organizations demonstrate good evidence of testing practices. The absence of reports, inadequate remediation documentation or vagueness in the definition of scope may complicate the task of proving that security testing has facilitated the control environment of the organization.

Best Practices for SOC 2 Penetration Testing in 2026
Penetration testing should be a component of the carefully planned security program and not a compliance project when organizations are preparing to have their SOC 2 audits. The creation of regular testing procedures can assist in ensuring that security tests are based on a realistic architecture and a real operational environment that is being audited.
The adoption of clear processes is also effective in the organization because it allows the company to show that the testing outcomes are analyzed and applied to enhance internal security measures.
Define a Clear System Boundary
Organizations are supposed to make a clear documentation of the systems that are within the SOC 2 audit before engaging in penetration testing. This normally entails the identification of applications, infrastructure, and supporting services that archive or process customer data.
An effective system boundary also makes sure that testing activities are done on the right environments.
Align Testing With Technology Architecture
The scope of testing ought to be a true reflection of the technology stack of the organization. In the case of SaaS, this usually comprises web applications, APIs, authentication platforms, and cloud infrastructure and administrator interfaces.
Assessment of these elements can also assist organizations on how vulnerabilities can be used to compromise the system security of the entire platform.
Maintain Evidence for Audit Review
SOC 2 auditors usually examine documentation that proves the existence of testing activities and issues that were identified and resolved. The records of penetration testing results, remediation measures, and testing findings should be organized to facilitate the presentation of clear audit evidence by organizations.
Track Remediation and Retesting
Once the vulnerabilities are identified, organizations ought to monitor the remedial efforts and confirm remedies by conducting follow-up testing. Restesting assists in ensuring that security vulnerabilities have been fixed and eliminates the re-occurring challenges in the production systems.
Regular monitoring of the remediation process shows that the organization is actually taking steps to control vulnerabilities detected during security testing.
