Cybersecurity Audit & Web Application Security Services

We follow a structured five-phase audit methodology that covers every attack surface of your web application. Phase one is reconnaissance and information gathering — understanding your architecture, identifying exposed endpoints, mapping subdomains, and reviewing publicly available information. Phase two is automated vulnerability scanning using industry-standard tools like Burp Suite Professional, OWASP ZAP, and Acunetix, covering all OWASP Top 10 categories.

Phase three is manual penetration testing, where our security engineers attempt to exploit the vulnerabilities identified in the automated scan. This phase covers business logic flaws that automated tools miss — privilege escalation paths, IDOR in API endpoints, race conditions in payment flows, and authentication bypass techniques. Phase four is dependency and supply chain analysis, auditing every package in your lock file against the National Vulnerability Database (NVD) and GitHub Advisory Database.

Phase five is reporting and remediation planning. We deliver a comprehensive report with each finding categorised by severity (Critical, High, Medium, Low), CVSS score where applicable, a proof-of-concept for exploitable vulnerabilities, and step-by-step remediation instructions. For clients who need hands-on help, we offer a remediation engagement where our engineers implement the fixes and re-test until all critical and high-severity findings are resolved.

Web application attacks have increased 300% since 2022, with automated bots scanning for vulnerabilities within hours of a new deployment. The average cost of a data breach now exceeds $5 million according to IBM's Cost of a Data Breach Report 2025, and regulatory penalties under DPDP Act in India can reach ₹250 crores for significant breaches. A single unpatched dependency or misconfigured S3 bucket can expose your entire customer database.

Security is not a one-time activity — it must be embedded in your development lifecycle. We recommend quarterly external scans, annual full penetration tests, and continuous dependency monitoring via GitHub Dependabot or Snyk. Our clients who follow this cadence typically reduce their critical and high-severity findings by 90% within 12 months and maintain a clean security posture through every subsequent audit cycle.

For businesses handling payment data, healthcare records, or EU citizen data, security audits are also a compliance requirement. PCI-DSS requires quarterly external scans and annual penetration tests. HIPAA requires regular security evaluations. GDPR mandates data protection impact assessments. And India's DPDP Act requires reasonable security safeguards — a penetration test is the industry-standard way to demonstrate this.

Our web application security audit covers authentication and session management review, API endpoint analysis for IDOR and mass assignment vulnerabilities, SQL/NoSQL injection testing, cross-site scripting (XSS) detection including DOM-based variants, and security header audit (CSP, HSTS, X-Frame-Options, X-Content-Type-Options). We also review cloud infrastructure configurations — S3 bucket permissions, database network access, IAM role policies, and WAF rules.

For mobile applications, we audit API communication security (TLS configuration, certificate pinning), local storage inspection, reverse engineering resistance, and third-party SDK risk assessment. For fintech applications, we perform PCI-DSS scope assessments, payment flow security review, and tokenization layer validation. For healthcare applications, we audit HIPAA compliance controls including audit logging, access controls, and encryption at rest and in transit.

We also offer DevSecOps integration services — embedding SAST (Static Application Security Testing) tools like SonarQube and Semgrep into your CI/CD pipeline, configuring DAST (Dynamic Application Security Testing) scans in your staging environment, and setting up dependency monitoring with automated pull requests for vulnerable packages. This shifts security left and catches vulnerabilities before they reach production.
