Choosing a CERT-In empanelled auditor involves more than checking empanelment status. As a CISO, you also need to evaluate the technical skills of the team, their penetration testing approach, and their experience with your technology environment. Empanelment confirms that the organization meets CERT-In’s requirements, but it does not by itself tell you how deeply the team will test your systems.
In this blog, we explain how to evaluate the technical expertise of a CERT-In empanelled auditor, from team credentials and testing capabilities to methodology, reporting, and retesting support.
1. Verify the Auditor’s CERT-In Empanelment
A. Check the Auditor’s Current Empanelment Status
First, confirm that the auditor is currently empanelled by CERT-In. Check the official List of CERT-In empanelled companies rather than relying only on information provided by the vendor.
B. Verify the Legal Entity and Applicable Audit Scope
Make sure the legal name of the company matches the CERT-In empanelled organization List name. Also confirm that the auditor can provide the type of information security audit your organization requires.
C. Review Relevant Industry Experience
Ask whether the auditor has worked with organizations in your sector. Experience in BFSI, fintech, healthcare, SaaS, government, or other regulated industries can help the team understand sector-specific security requirements.
D. Check Experience with Similar Enterprise Environments
Your auditor should understand the technologies used by your organization. For example, if you operate a large SaaS platform with APIs and cloud infrastructure, ask whether the testing team has assessed similar environments.
2. Evaluate the Security Team’s Technical Credentials
The company may have strong credentials, but you should also understand who will actually perform your assessment.
A. Review Certifications of Assigned Security Professionals
Ask for the qualifications of the security professionals assigned to your project. Certifications such as OSCP, CREST, GPEN, CEH, CISSP, and CISA can provide useful information about their training and experience.
Certifications should not be the only selection factor. Practical testing experience matters just as much.
B. Look for Offensive Security and Application Security Expertise
A good testing team should understand how attackers identify and exploit weaknesses in applications, APIs, authentication systems, cloud environments, and infrastructure.
C. Assess Experience with Complex Security Assessments
Ask about previous projects involving large applications, multiple user roles, APIs, cloud platforms, microservices, or complex business workflows.
D. Confirm the Involvement of Senior Security Pentesters
Find out who will perform the key parts of the assessment. Senior Pentesters should be involved when the environment includes complex applications, sensitive data, or critical business functions.
3. Assess the Auditor’s Web Application Security Expertise
A web application assessment should cover more than common vulnerabilities found by automated scanners.
A. OWASP-Based Web Application Testing
Ask whether the team uses recognized resources such as the OWASP Web Security Testing Guide and OWASP Top 10 as part of its testing approach.
B. Authentication and Session Management Testing
The team should examine login controls, password policies, MFA, session handling, password resets, cookies, and authentication tokens.
C. Authorization and Access Control Testing
Pentesters should check whether users can access functions or data that belong to other users or higher-privileged roles. For example, changing an account ID in a request should not allow one customer to view another customer’s information.
D. Injection and Input Validation Testing
The security assessment should check for vulnerabilities such as SQL injection, command injection, cross-site scripting, and other input-related attacks.
E. Business Logic Security Testing
Ask how the Pentesting team tests business workflows. Some vulnerabilities only appear when a tester changes the expected sequence of actions. For example, a pentester may check whether a customer can receive a discount multiple times, bypass an approval step, or submit the same transaction more than once.
F. Sensitive Data Exposure Assessment
The Pentester team should check whether personal, financial, authentication, or business-sensitive information is exposed through applications, APIs, error messages, logs, or client-side code.
4. Evaluate API and Modern Application Security Capabilities
APIs often connect applications, users, databases, and third-party services. Your auditor should be able to test these connections properly.
A. REST and GraphQL API Security Testing
Ask whether the Pentesting team has experience testing REST and GraphQL APIs, including endpoints that are not directly visible through the application’s user interface.
B. API Authentication and Authorization Testing
Pentesters should verify that every sensitive API endpoint properly authenticates users and checks their permissions.
C. Token and Session Security Assessment
The assessment should examine access tokens, refresh tokens, expiration, token validation, and session handling.
D. Microservices and Service-to-Service Security
If your application uses microservices, ask how the auditor evaluates communication and authorization between internal services.
E. Third-Party API and Integration Testing
Third-party integrations should also be considered where they fall within the agreed scope. Weak controls in external integration can affect the security of your application.
5. Check Cloud and Infrastructure Security Expertise
Application security does not stop at the application layer. Cloud and infrastructure settings can also expose sensitive systems.
A. AWS, Azure, and Google Cloud Security Assessments
Ask whether the Pentesting team has experience assessing your cloud platform and understands its security services and configuration options.
B. Cloud IAM and Privilege Review
The auditor should examine identity and access management settings to identify excessive permissions and inappropriate access.
C. Network Segmentation and Exposure Testing
The assessment should identify unnecessary network exposure and review whether sensitive systems are properly separated from less trusted environments.
D. Server Hardening and Configuration Reviews
Pentesters should review important server and infrastructure settings for weak configurations, unnecessary services, default accounts, and other security concerns.
E. Internet-Facing Asset Assessment
Ask how the auditor identifies publicly accessible systems, services, and assets that fall within the assessment scope.
6. Ask About Manual and Automated Testing
This is one of the most important areas to discuss before hiring an auditor.
A. What Automated Security Tools Does the Auditor Use?
Automated tools can help identify known vulnerabilities and configuration issues quickly. Ask which tools the team uses and how they fit into the overall assessment.
B. How Much Manual Testing Is Included?
Manual testing allows security professionals to investigate application behavior beyond standard scanner checks. Ask for a clear explanation of how much manual testing your engagement includes.
C. How Are Scanner Findings Manually Validated?
A scanner may report a potential vulnerability that requires further investigation. Experienced testers should verify findings before including them in the final report.
D. How Does the Team Identify Business Logic Vulnerabilities?
Ask for examples of how testers examine workflows, user roles, transactions, approvals, discounts, payments, and other business functions.
E. Can Testers Chain Multiple Findings into Attack Scenarios?
Some security issues become more serious when combined. Ask whether the team looks at how multiple weaknesses could be used together.
7. Review the Auditor’s Testing Methodology
A clear methodology helps you understand what the assessment will cover and how testing will be performed.
A. OWASP Web Security Testing Guide (WSTG)
For web applications, ask whether the testing approach covers relevant areas from the OWASP WSTG.
B. OWASP Top 10
The OWASP Top 10 provides a useful reference for common web application security risks. However, your assessment should not stop at these categories.
C. Penetration Testing Execution Standard (PTES)
PTES provides a structured approach to penetration testing, covering areas such as pre-engagement interactions, intelligence gathering, vulnerability analysis, exploitation, and reporting.
D. NIST Security Testing Practices
Ask whether the testing approach also considers applicable NIST security assessment practices where relevant to your environment.
E. CERT-In Requirements Where Applicable
For assessments performed to meet CERT-In-related requirements, confirm that the auditor understands and follows the applicable CERT-In expectations.
8. Examine the Quality of Previous Security Reports
A security assessment is only useful if your teams can understand the findings and act on them.
A. Executive Summary for Business Leaders
The report should explain the overall security position in language that executives and business stakeholders can understand.
B. Detailed Technical Findings
Technical teams need enough information to understand each vulnerability, its affected asset, severity, evidence, and recommended fix.
C. Proof of Concept and Supporting Evidence
Ask whether findings include evidence showing how the issue was verified. This helps developers reproduce and address vulnerabilities.
D. Risk Ratings and Business Impact
A good report should explain why a finding matters to the organization, not simply assign a severity score.
E. Clear Remediation Recommendations
Recommendations should give technical teams practical direction for addressing each issue.
F. Scope, Limitations, and Testing Coverage
The report should clearly state what was tested, what was excluded, and any limitations that affected the assessment.
9. Evaluate Remediation and Retesting Capabilities
Your relationship with the auditor should not end when the first report is delivered.
A. How Does the Auditor Validate Security Fixes?
Ask how the penetration team verifies that vulnerabilities have been properly resolved after remediation.
B. Are Retesting Cycles Included?
Confirm how many retesting cycles are included in the engagement and whether there are additional charges.
C. Does the Final Report Document Verified Closures?
The final documentation should clearly show which findings were fixed and which remain open.
D. Can the Auditor Identify Issues Introduced During Remediation?
Changes made to fix one vulnerability can sometimes affect other security controls. Ask whether the retest also considers related security risks.
10. Questions to Ask Before Hiring a CERT-In Empanelled Auditor
Before signing an agreement, ask direct questions about the people, methodology, scope, reporting, and post-assessment support.
A. Who Will Perform the Assessment?
Ask for the roles, experience, and relevant qualifications of the security professionals assigned to your project.
B. What Certifications and Experience Does the Testing Team Have?
Look beyond the company’s certifications. Review the credentials and practical experience of the people conducting the assessment.
C. How Much Manual Testing Will Be Performed?
Ask for a clear explanation of the manual testing activities included in the engagement.
D. Which Applications, APIs, and Infrastructure Will Be Tested?
Confirm the complete scope before testing begins. Make sure important applications, APIs, cloud resources, and infrastructure are not unintentionally excluded.
E. Can You Share a Redacted Sample Report?
A sample report can help you evaluate the quality of technical findings, evidence, risk ratings, executive summaries, and remediation guidance.
F. How Will You Handle Production Testing?
Ask about testing windows, rules of engagement, communication procedures, and measures used to avoid unnecessary impact on production systems.
G. Is Retesting Included in the Engagement?
Confirm whether the auditor will verify security fixes and provide updated findings after remediation.
H. How Will Vulnerabilities Be Prioritized?
Ask whether the auditor considers CVSS, exploitability, affected assets, data sensitivity, and business impact when ranking findings.
The best auditor is not simply the one with the right certification. Look for a team that can understand your technology, test beyond automated checks, explain findings clearly, and help your teams verify fixes.
