Enterprise customers often review a vendor’s security practices before signing a contract or approving access to their systems and data. A VAPT assessment can provide documented evidence of security testing, identified vulnerabilities, remediation, and retesting.
In this blog, we explain how VAPT supports customer security questionnaires, vendor assessments, security reviews, and enterprise onboarding, along with common gaps businesses should avoid.
Why Security Testing Matters During Vendor Assessments?
Enterprise customers often review a vendor’s security practices before signing a contract or approving access to sensitive systems. A VAPT assessment gives customers documented evidence that applications and infrastructure have been tested for security weaknesses.
1. Enterprise Customers Review Vendor Security Before Contracts
Large customers may assess a vendor’s security posture as part of procurement and vendor risk management. They may ask about vulnerability management, penetration testing, access controls, incident response, and security policies.
2. Security Questionnaires Require Evidence
A questionnaire may ask whether the vendor performs regular security testing, when the last assessment was completed, and whether identified vulnerabilities were fixed. A current VAPT report can help support these responses with documented information.
3. VAPT Reports Help Demonstrate Security Testing
A VAPT report can show the assessment scope, applications and systems tested, testing methods, identified vulnerabilities, severity ratings, evidence, and remediation recommendations. This gives customer security teams a clearer view of the assessment performed.
4. Security Findings Can Affect Vendor Approval
Customer security teams may review critical and high-risk findings before approving a vendor. Unresolved vulnerabilities may result in additional questions, remediation requirements, or further security reviews.
5. Current Security Reports Support Faster Review Cycles
An up-to-date VAPT report can reduce the need to gather security evidence from multiple teams. It can also help answer technical questions during procurement and customer security reviews.
What Do Customers Typically Ask During Security Assessments?
Customer questionnaires can cover several areas of application and infrastructure security. Vendors should be prepared to provide clear answers and supporting evidence.
1. Do You Perform Regular VAPT Testing?
Customers may want to know whether security testing is performed on a defined schedule or after significant application and infrastructure changes.
2. When Was Your Last Security Assessment?
The assessment date helps customers understand how current the security information is.
3. Which Applications and Assets Were Tested?
The customer may review whether the assessment included web applications, APIs, servers, cloud environments, networks, databases, and other relevant assets.
4. Were APIs Included in the Assessment?
APIs often handle authentication, business transactions, and sensitive data. Customers may therefore ask whether API endpoints were included in security testing.
5. Was Manual Penetration Testing Performed?
Manual testing can examine application behavior, access controls, business logic, and attack paths that automated scanners may not identify.
6. Were Critical and High-Risk Findings Remediated?
Customers may ask for the status of significant vulnerabilities and whether appropriate corrective actions were completed.
7. Was Retesting Performed After Remediation?
Retesting helps confirm whether reported vulnerabilities were successfully addressed.
8. Can You Provide the Security Assessment Report?
Depending on confidentiality requirements, a vendor may provide a complete report, executive summary, attestation, or suitably redacted version.
How VAPT Helps Address Enterprise Security Questionnaires?
A well-documented VAPT assessment can provide information that supports several common security review questions.
1. Provides Evidence of Vulnerability Testing
The report documents that security testing was performed against the agreed scope.
2. Documents the Testing Scope
Customers can see which applications, APIs, infrastructure, and environments were assessed.
3. Shows Identified Security Findings
The report records vulnerabilities discovered during testing along with their severity and technical details.
4. Records Risk and Severity Ratings
Findings can be categorized according to their security impact and risk level.
5. Documents Remediation Activities
Organizations can maintain records showing how identified vulnerabilities were addressed.
6. Provides Retesting Results
Retest results can show whether previously reported findings remain open or have been resolved.
7. Supports Security Control Verification
VAPT results can provide additional evidence when customers review application security, authentication, authorization, and infrastructure controls.
NIST describes penetration testing as a method for identifying vulnerabilities and evaluating the effectiveness of security controls.
How VAPT Helps During Enterprise Vendor Onboarding?
Security testing can also support the vendor approval process by giving procurement, security, and risk teams documented information about the vendor’s security practices.
1. Supports Security Due Diligence
A VAPT report gives customer security teams information they can use when evaluating a vendor.
2. Helps Answer Technical Security Questions
Assessment results can help vendors respond to questions about vulnerabilities, testing coverage, remediation, and security controls.
3. Provides Independent Security Assessment Evidence
An assessment performed by an independent security team can provide additional evidence for customer review.
4. Helps Procurement Teams Review Security Documentation
Procurement teams can use available security reports and supporting documents when coordinating with internal security and risk teams.
5. Supports Customer Risk Assessments
VAPT findings can help customers understand the types of security weaknesses identified and the actions taken to address them.
6. Helps Demonstrate Vulnerability Management Practices
Assessment, remediation, and retesting records can show that vulnerabilities are tracked and addressed through a defined process.
NIST supply-chain guidance recommends assessing supplier cybersecurity practices and using appropriate assessment or verification methods where applicable.
How Remediation and Retesting Affect Vendor Assessments?
Finding a vulnerability is only one part of the security assessment process. Customers may also want to know how the organization responded to the findings.
1. Critical Findings Should Be Addressed Promptly
High-impact vulnerabilities should receive immediate attention based on the organization’s risk management process.
2. High-Risk Findings Should Have Clear Remediation Plans
Each significant finding should have an assigned owner, target date, and documented remediation approach.
3. Remediation Activities Should Be Documented
Teams should maintain records of code changes, configuration updates, patches, or other corrective actions.
4. Fixed Vulnerabilities Should Be Retested
Security testers can verify whether the original vulnerability has been resolved and whether the same attack path remains possible.
5. Final Reports Should Show Updated Finding Status
The final assessment record should clearly indicate which findings are closed, open, partially addressed, or otherwise handled.
6. Remaining Risks Should Be Properly Documented
If a vulnerability cannot be fixed immediately, the organization should document the reason, risk treatment, ownership, and planned next steps.
Retesting provides additional evidence that corrective actions have been checked after vulnerabilities are identified. NIST assessment guidance also supports follow-up testing to verify mitigation actions.
Common VAPT Gaps That Can Create Problems During Vendor Assessments
A weak or outdated VAPT process can make it harder for businesses to answer customer security questions. Common gaps include:
1. Using an Outdated VAPT Report
An old report may not reflect the current application, infrastructure, APIs, or security controls. Customers may ask for a recent assessment before approving a vendor.
2. Testing Only the Main Web Application
Testing only the primary website can leave other important systems outside the assessment. APIs, mobile backends, cloud services, and supporting infrastructure may also need to be reviewed.
3. Excluding APIs From the Scope
APIs often handle authentication, customer data, transactions, and internal services. Leaving them out can create gaps in the security assessment.
4. Relying Only on Automated Scanners
Automated tools can identify many known vulnerabilities, but they may not detect business logic flaws, complex access-control issues, or attack paths that require manual testing.
5. Leaving Critical Findings Unresolved
Open critical or high-risk findings can raise concerns during customer security reviews. Businesses should have clear remediation plans and documented progress.
6. Not Providing Remediation Evidence
Customers may want proof that reported vulnerabilities were addressed. Fix records, configuration changes, screenshots, and other supporting evidence can help demonstrate remediation.
7. Skipping Retesting
A vulnerability should not automatically be marked as closed after a fix is applied. Retesting helps confirm whether the reported issue has actually been resolved.
8. Having Different Security Information Across Documents
Conflicting information in VAPT reports, questionnaires, policies, and security documents can create questions during vendor reviews. Businesses should keep their security information consistent and updated.
How Businesses Can Prepare for Customer Security Reviews?
Good preparation helps businesses respond to security questionnaires with accurate information and supporting documents.
1. Keep a Current VAPT Report
Maintain a recent assessment that reflects the applications, APIs, infrastructure, and environments currently in use.
2. Maintain an Updated Asset Inventory
Keep records of domains, applications, APIs, cloud resources, servers, and other assets included in the security program.
3. Include Applications and APIs in the Assessment Scope
Make sure customer-facing applications and their supporting APIs are included where applicable.
4. Track Vulnerabilities and Remediation
Maintain a central record of findings, assigned owners, remediation dates, and current status.
5. Keep Retesting Evidence Available
Store retest reports and supporting evidence showing which vulnerabilities were successfully resolved.
6. Maintain Security Policies and Supporting Documents
Keep relevant policies for access control, vulnerability management, incident response, data protection, and other security practices current.
7. Assign a Team to Handle Customer Security Questions
A designated security or compliance team can provide consistent answers and quickly locate supporting evidence.
8. Review Security Documentation Before Enterprise Sales Discussions
Review VAPT reports, questionnaires, certifications, and other security documents before sharing them with prospective customers.

When Should Businesses Perform VAPT Testing for Customer Requirements?
VAPT should be planned around business, technology, and customer requirements rather than treated as a one-time activity.
1. Before Approaching Enterprise Customers
A current VAPT report can provide useful security evidence when starting discussions with large customers.
2. Before Vendor Onboarding
Complete the assessment before a customer begins its formal security review when possible.
3. Before Major Product Releases
Testing before a major release can help identify vulnerabilities before customers gain access to new functionality.
4. After Significant Application Changes
Major changes to application architecture, authentication, authorization, or important workflows may require additional security testing.
5. After Major API or Cloud Changes
Changes to APIs, cloud infrastructure, permissions, or exposed services can introduce new security risks.
6. Before Customer Security Reviews
Having current findings, remediation records, and retesting evidence ready can make it easier to respond to customer questions.
7. At Least Annually for Ongoing Security Assurance
An annual VAPT can provide a recurring assessment point, while additional testing may be appropriate after major changes or security incidents.
