FSN TECH - VAPT Approach

At FSN Tech, our Vulnerability Assessment and Penetration Testing (VAPT) approach is designed to move beyond surface-level scanning and deliver validated, real-world security insights.

We combine structured vulnerability discovery with controlled exploitation techniques to identify not only what is vulnerable, but what is actually exploitable in your environment.

Our methodology follows globally accepted security frameworks such as OWASP and NIST, ensuring assessments are technically rigorous, repeatable, and audit-ready. Every engagement begins with clear scoping and rules of engagement, followed by asset discovery, automated analysis, and deep manual verification to eliminate false positives and highlight true business risk.

The outcome is not just a report, but actionable security intelligence—including executive summaries, technical findings with evidence, and practical remediation guidance. 

 

What We Assess

Comprehensive Security Assessments Across Your Digital Environment

FSN Tech Solutions performs risk-based security assessments across applications, infrastructure, cloud platforms and enterprise networks to identify vulnerabilities before they can be exploited.

Our Methodology

A Structured Approach to Security Testing

Each engagement follows a defined methodology to ensure consistent coverage, accurate validation and actionable outcomes.

  1. Scope Definition & Planning

Work with stakeholders to define assessment objectives, target environments, testing windows, communication procedures and rules of engagement.

  1. Information Gathering

Collect publicly available and technical information to understand the attack surface and identify potential entry points.

  1. Vulnerability Identification

Perform automated vulnerability scanning supported by manual verification to identify security weaknesses across the agreed scope.

  1. Exploitation & Validation

Safely validate identified vulnerabilities to determine exploitability, business impact and likelihood of compromise.

  1. Risk Analysis

Assess findings using CVSS along with business context to prioritize remediation activities based on operational risk.

  1. Reporting

Document validated vulnerabilities, supporting evidence, affected assets, risk ratings and practical remediation recommendations.

  1. Remediation Support & Retesting

Verify implemented fixes through targeted retesting and confirm successful remediation before engagement closure.

Reporting Approach

Reports Designed for Both Technical Teams and Business Stakeholders

Every engagement includes reports that support remediation planning, management review and compliance activities.

Executive Summary

A high-level overview of the assessment scope, overall security posture, key risks and recommended priorities. 

Technical Report

Comprehensive documentation of each validated vulnerability, including:

  • Description
  • Business impact
  • Risk rating
  • Affected assets
  • Proof of concept
  • Supporting screenshots
  • Reproduction steps
  • Recommended remediation

Risk Prioritization

Findings are categorized based on severity and business impact to support efficient remediation planning.

Compliance Mapping

Where applicable, findings may be mapped to recognized frameworks such as:

  • OWASP
  • NIST Cybersecurity Framework
  • CIS Controls
  • ISO/IEC 27001
  • CERT-In guidelines

Retesting Process

Validating That Security Issues Have Been Resolved

After remediation activities are completed, focused retesting is performed to verify that identified vulnerabilities have been effectively addressed.

The retesting process includes:

  • Verification of implemented fixes
  • Confirmation that vulnerabilities are no longer exploitable
  • Validation of configuration changes
  • Assessment of any remaining residual risk
  • Documentation of remediation status

A Retest Report is issued summarizing verified fixes and any outstanding observations. 

Typical Deliverables

Each VA-PT engagement concludes with documentation that supports technical remediation, executive reporting and compliance activities.

Executive Assessment Report

A concise summary of the engagement, key findings, overall risk profile and recommended next steps.

Detailed Technical Report

Comprehensive vulnerability documentation including evidence, risk analysis, reproduction steps and remediation guidance.

Risk Matrix

A consolidated view of identified vulnerabilities categorized by severity and business impact.

Evidence Repository

Supporting screenshots, logs, proof-of-concept results and technical observations collected during testing.

Remediation Recommendations

Prioritized technical recommendations with implementation guidance for reducing identified risks.

Compliance Mapping (Optional)

Mapping of findings to applicable security standards or regulatory requirements.
