Launching a new product without checking its security can leave vulnerabilities undiscovered until after users start accessing the application. A pre-launch VAPT assessment helps identify security weaknesses across the application, APIs, authentication controls, configurations, and supporting infrastructure.
In this blog, we cover the key VAPT checks IT managers should complete before product launch, including scope preparation, application and API testing, authentication, access control, configuration reviews, business logic testing, vulnerability remediation, retesting, and final security sign-off. OWASP’s Web Security Testing Guide covers these areas as part of a structured web application security testing approach.
A. Define the VAPT Scope Before Testing
Before testing starts, the IT team should create a complete list of systems and services connected to the product. A clear scope helps the security team test the correct assets and reduces the chance of missing an exposed component.
1. List All Applications and Subdomains
Prepare a list of the main application, subdomains, portals, admin panels, and other related web properties. Include both customer-facing and internal applications that are part of the launch.
2. Identify Public-Facing Assets
Document every asset accessible from the internet, including domains, IP addresses, web servers, remote access portals, and externally available services.
3. Include APIs and Web Services
Add REST APIs, GraphQL endpoints, web services, and other backend interfaces to the testing scope. APIs can expose sensitive functions and data even when the main application appears secure.
4. Identify Cloud and Hosting Infrastructure
Document cloud accounts, virtual machines, containers, storage services, load balancers, databases, and other hosting components that support the application.
5. Document Production and Staging Environments
Clearly separate production, staging, development, and testing environments. This helps the security team understand which environment is approved for testing and prevents confusion during the assessment.
6. Confirm Third-Party Integrations
List payment gateways, identity providers, analytics services, messaging platforms, external APIs, and other third-party connections used by the product.
OWASP recommends identifying application entry points before detailed security testing, so testers can understand the application’s exposed functionality and possible attack paths.
B. Check Authentication and Account Security
Authentication controls determine how users prove their identity and access their accounts. These controls should be tested before launch to identify weaknesses that could allow unauthorized access.
1. Test Login Mechanisms
Check whether login functions properly enforce authentication and prevent unauthorized access.
2. Review Password Policies
Check password length, complexity, reuse restrictions, and other controls that protect user accounts.
3. Test Multi-Factor Authentication
Where MFA is implemented, verify that it is correctly enforced and cannot be bypassed through alternative login paths.
4. Review Password Reset and Account Recovery
Test whether password recovery can be abused to take control of another user’s account.
5. Test Session Management
Check how sessions are created, maintained, invalidated, and protected after login.
6. Check Session Timeout and Logout Controls
Verify that sessions expire appropriately and that logout properly invalidates active sessions.
7. Review Cookie Security
Check authentication cookies for appropriate attributes such as Secure, HttpOnly, and SameSite.
8. Test Account Lockout and Rate Limiting
Check whether repeated login attempts are controlled to reduce password guessing and automated attacks.
C. Test Authorization and Access Controls
Authentication confirms who a user is, while authorization determines what that user is allowed to access. Both should be tested before launch.
1. Test Role-Based Access Controls
Verify that users can access only the functions assigned to their roles.
2. Check Horizontal Privilege Escalation
Test whether one user can access another user’s information or functions by changing identifiers or request parameters.
3. Check Vertical Privilege Escalation
Verify that a standard user cannot access administrative or higher-privilege functions.
4. Test Access to Restricted Functions
Attempt to access protected features directly rather than through the application’s normal navigation.
5. Review Direct Object Access
Check whether users can access records belonging to other users by modifying object or resource identifiers.
6. Test Administrative Functions
Review admin panels and privileged functions to confirm that access restrictions are properly enforced.
D. Perform Input Validation and Injection Testing
User-controlled input should be tested to determine whether it can alter application behavior or reach backend systems without proper validation.
1. SQL Injection Testing
Check whether application inputs can alter database queries or expose database information.
2. Cross-Site Scripting Testing
Test whether malicious scripts can be inserted into pages viewed by users.
3. Command Injection Testing
Check whether application input can reach operating system commands without appropriate controls.
4. Server-Side Request Forgery Testing
Assess whether the application can be manipulated into making unauthorized requests to internal or external services.
5. File Upload Security Testing
Check file type validation, upload restrictions, storage controls, and access to uploaded files.
6. Path Traversal Testing
Test whether users can manipulate file paths to access files outside the intended directory.
7. Input and Parameter Manipulation
Modify parameters, headers, cookies, and request values to identify unexpected application behavior.
OWASP’s testing guidance covers input validation, client-side security, authentication, authorization, session management, and business logic as important areas of application security testing.
E. Assess API Security Before Launch
APIs often provide direct access to application functions and data, making API security testing an important part of a pre-launch VAPT assessment.
1. Identify All API Endpoints
Create an inventory of available API endpoints, including documented and internally used interfaces that fall within the approved scope.
2. Test API Authentication
Check whether protected endpoints properly require authentication.
3. Test API Authorization
Verify that users can access only the resources and functions permitted for their account or role.
4. Review Token Validation
Check how access tokens, refresh tokens, and other authentication tokens are issued, validated, expired, and revoked.
5. Test Rate Limiting
Check whether APIs limit repeated requests appropriately for sensitive functions.
6. Check Excessive Data Exposure
Review API responses to identify sensitive information that is not required by the requesting user or application.
7. Test Parameter Manipulation
Modify API parameters and request values to check whether authorization and validation controls can be bypassed.
8. Review API Error Handling
Check whether API errors expose credentials, internal paths, database details, stack traces, or other sensitive technical information.
9. Test Third-Party API Integrations
Review authentication, authorization, data exchange, and security controls used when the application communicates with external services.
F. Test Business Logic and Application Workflows
Some security weaknesses are connected to how an application performs business processes rather than to a single technical flaw. Manual testing is useful for checking whether users can manipulate workflows or bypass required steps.
1. Test User Registration Workflows
Check whether registration controls can be bypassed or manipulated to create unauthorized accounts.
2. Test Payment and Checkout Processes
Review payment amounts, transaction states, discounts, refunds, and other controls that affect financial operations.
3. Test Account Management Functions
Check changes to email addresses, phone numbers, passwords, account ownership, and other important account settings.
4. Test Approval and Verification Workflows
Verify that users cannot bypass the required approvals or verification steps.
5. Test Subscription and Usage Limits
Check whether users can bypass plan limits, quotas, licensing restrictions, or usage controls.
6. Test Multi-Step Processes
Review whether required steps can be skipped, reordered, repeated, or accessed without completing earlier stages.
7. Check for Transaction Manipulation
Test whether transaction values, quantities, statuses, or identifiers can be changed without proper authorization.
8. Test Workflow Bypass Scenarios
Attempt to reach restricted application states through unexpected sequences of actions.
OWASP treats business logic testing as a distinct area because some vulnerabilities depend on application workflows and expected user behavior.
G. Review Security Configuration
Secure configuration should be checked before deployment because default settings, unnecessary services, and debugging features can create security exposure.
1. Check Web Server Configuration
Review server settings, enabled services, directory access, and other security-related configurations.
2. Review Application Security Settings
Check security settings within the application and supporting frameworks.
3. Remove Default Accounts and Files
Remove unused default accounts, sample files, test pages, and unnecessary components before launch.
4. Disable Debugging in Production
Ensure debug modes and detailed error displays are disabled in the production environment.
5. Review Security Headers
Check relevant HTTP security headers and confirm they are configured according to the application’s requirements.
6. Check Error Messages
Verify that application errors do not expose sensitive technical information.
7. Review Database Configuration
Check database access controls, exposed interfaces, default credentials, and unnecessary permissions.
8. Check Firewall and Network Rules
Review inbound and outbound rules to ensure that unnecessary services are not accessible.
9. Review Cloud Security Configurations
Check cloud storage permissions, security groups, IAM settings, exposed services, and other applicable configurations.
OWASP’s configuration and deployment testing guidance covers areas such as platform configuration, administrative interfaces, HTTP methods, and information disclosure.
H. Review Sensitive Data Protection
Before launch, IT managers should confirm that sensitive information is protected throughout collection, processing, transmission, storage, and logging.
1. Identify Sensitive Information
List customer, employee, financial, authentication, business, and other sensitive information handled by the application.
2. Check Data Encryption in Transit
Verify that sensitive information is protected when transmitted between users, applications, APIs, and services.
3. Review Data Encryption at Rest
Check appropriate protection for sensitive information stored in databases, files, backups, and cloud storage.
4. Test Sensitive Data Exposure
Check application pages, APIs, files, and other interfaces for unnecessary exposure of sensitive information.
5. Review API Responses for Excessive Data
Verify that APIs return only the information required for the intended function.
6. Check Logs for Sensitive Information
Review application and security logs to ensure passwords, tokens, payment details, and other sensitive information are not unnecessarily recorded.
7. Review Backup and Storage Security
Check access permissions, storage locations, backup protection, and retention controls for sensitive data.
I. Check Third-Party Components and Dependencies
Modern applications often rely on open-source libraries, frameworks, packages, and external services. These components should be reviewed before launch.
1. Review Open-Source Libraries
Create a list of libraries and frameworks used by the application.
2. Identify Outdated Dependencies
Check whether any components are outdated or no longer supported.
3. Check Known Vulnerabilities
Review dependencies for publicly known security vulnerabilities.
4. Review Third-Party Services
Assess the security role of external services that process application data or provide important functionality.
5. Maintain a Software Component Inventory
Keep an updated record of software components used in the product.
6. Review Dependency Management Processes
Check how dependencies are selected, updated, monitored, and removed when required.
NIST’s Secure Software Development Framework includes practices for identifying and addressing vulnerabilities in software throughout development and release processes.
J. Review Cloud and Infrastructure Security
The infrastructure supporting the product should be assessed along with the application itself.
1. Check Publicly Exposed Services
Identify services accessible from the internet and confirm that each exposed service is required.
2. Review Cloud IAM Permissions
Check whether users, applications, and services have only the permissions required for their functions.
3. Check Network Segmentation
Review whether sensitive systems are appropriately separated from public-facing systems and other network zones.
4. Review Security Groups and Firewall Rules
Check inbound and outbound access rules for unnecessary or overly broad permissions.
5. Test Internet-Facing Servers
Assess externally accessible servers and services for vulnerabilities and insecure configurations.
6. Review Storage Permissions
Check whether cloud storage, databases, and file repositories are accessible only to authorized users and services.
7. Check Administrative Interfaces
Review management portals and administrative services for access restrictions and secure authentication.
8. Review Server Hardening
Check operating system settings, unnecessary services, access controls, patch levels, and other hardening measures.
K. Review Security Testing Results
Testing should combine automated tools with manual security assessment to provide broader coverage.
1. Run Vulnerability Scans
Use appropriate scanners to identify known vulnerabilities, outdated components, and configuration issues.
2. Perform Manual Penetration Testing
Security testers should manually assess authentication, authorization, business logic, APIs, input handling, and other areas that require human analysis.
3. Validate Scanner Findings
Review automated findings manually to confirm whether reported vulnerabilities are valid and applicable.
4. Investigate High-Risk Findings
Prioritize findings that could result in unauthorized access, sensitive data exposure, privilege escalation, or major business impact.
5. Check for Vulnerability Chaining
Assess whether multiple weaknesses can be combined to create a higher-impact attack path.
6. Document Testing Coverage
Record the assets, functions, technologies, and security areas that were tested.
A VAPT assessment should not rely only on automated scanning. OWASP’s testing framework includes manual testing and other assessment techniques alongside automated tools.
L. Review and Prioritize VAPT Findings
Once testing is complete, IT managers should review the findings and assign clear ownership for remediation.
1. Identify Critical Vulnerabilities
Review vulnerabilities that could cause severe security or business consequences.
2. Review High-Risk Findings
Ensure high-risk issues are assigned to the appropriate teams for prompt remediation.
3. Assess Medium and Low-Risk Findings
Review lower-severity findings and determine their appropriate remediation timelines.
4. Understand Business Impact
Consider how each finding could affect customers, systems, data, operations, revenue, or compliance requirements.
5. Assign Remediation Owners
Each finding should have an identified person or team responsible for addressing it.
6. Set Remediation Deadlines
Set target dates based on severity, business impact, and launch requirements.
7. Track Open and Closed Findings
Maintain a record of remediation progress and final status.
M. Complete Vulnerability Remediation Before Launch
Security findings should be addressed before the product moves into production, particularly vulnerabilities with significant impact.
1. Fix Critical and High-Risk Findings
Prioritize vulnerabilities that could expose sensitive data, enable unauthorized access, or compromise important functions.
2. Review Security Fixes
Development and security teams should review implemented fixes to confirm that they address the reported issue.
3. Check for Regression Issues
Verify that security changes have not affected existing security controls or application functions.
4. Update Vulnerable Dependencies
Upgrade or replace components with known security issues where appropriate.
5. Correct Security Misconfigurations
Address insecure cloud, server, database, application, and network settings identified during testing.
6. Document Remediation Evidence
Keep records of code changes, configuration updates, screenshots, tickets, or other evidence that supports remediation.
N. Perform VAPT Retesting
A VAPT assessment should not end when the first report is delivered. Retesting verifies whether reported vulnerabilities have actually been addressed.
1. Retest Fixed Vulnerabilities
Test each remediated finding again using appropriate validation steps.
2. Verify That Security Controls Work as Expected
Confirm that the implemented fix prevents the previously demonstrated attack path.
3. Check for New Issues After Remediation
Review whether changes made during remediation introduced additional security problems.
4. Confirm Closed Findings
Mark a finding as closed only after the security tester has verified the fix.
5. Document Remaining Open Findings
Clearly record any vulnerabilities that remain unresolved before launch.
6. Obtain the Updated VAPT Report
Keep the final report and retesting results as part of the product’s security documentation.
O. Complete the Pre-Launch Security Sign-Off
The final step is to confirm that security testing, remediation, and risk review are complete before production deployment.
1. Confirm VAPT Scope Is Complete
Verify that all approved applications, APIs, infrastructure, and other assets were assessed.
2. Review the Final VAPT Report
IT, security, development, and management teams should review the final assessment results.
3. Confirm Critical Findings Are Resolved
Verify that critical security issues have been fixed and successfully retested before launch.
4. Review Remaining Risk Acceptances
If any findings remain open, ensure they have been formally reviewed and accepted by the appropriate authority.
5. Confirm Production Configuration
Check that the production environment matches the security configuration reviewed during the assessment.
6. Verify Monitoring and Logging
Confirm that security monitoring, logging, alerting, and relevant operational controls are active before launch.
7. Confirm Incident Response Contacts
Make sure security and technical teams know whom to contact if a security incident occurs after deployment.
8. Obtain Final Security Approval
Complete the required internal approval before moving the product into production. This provides a clear record that the application has passed the organization’s pre-launch security review.
