Web application penetration testing

Prices starting at $4,999.

Web application penetration testing is a manual security assessment in which ethical hackers simulate real-world cyberattacks against your web application and its backend APIs to uncover the vulnerabilities attackers and auditors care about most, before they reach production.

A web app pentest goes beyond a vulnerability scan: scanners flag known issues, but only a manual web application penetration test exploits chained flaws and uncovers business-logic vulnerabilities that no automated tool can find on its own.

Blaze 's web application penetration testing is delivered by CREST-accredited offensive security engineers certified OSCP, OSWE, OSCE and CRTO, and is suitable for applications hosted on AWS and beyond. We follow OWASP Top 10 (2021), OWASP ASVS, OWASP API Security Top 10, OWASP Web Security Testing Guide (WSTG), NIST SP 800-115, OSSTMM and PTES, and supplement automated scanners with custom tooling - Burp Suite, OWASP ZAP, Caido, SQLmap and in-house scripts.

A single web app pentest report supports vendor risk assessments and compliance audits including SOC 2, ISO 27001, PCI DSS 4.0, HIPAA, GDPR and CCPA/CPRA.

Our web application security audit, also known as web app pentest, web app pen testing or pentesting for web applications, covers the full set of OWASP Top 10 (2021) risk categories and the WSTG checklists:

• A01 Broken Access Control - IDOR, vertical and horizontal privilege escalation, multi-tenant authorization
• A02 Cryptographic Failures - weak hashing, plaintext storage, TLS misconfiguration, sensitive data exposure
• A03 Injection - SQL injection, NoSQL injection, command injection, HTML / template injection, LDAP injection
• A04 Insecure Design - business-logic flaws, race conditions, abuse cases
• A05 Security Misconfiguration - default credentials, verbose errors, unsafe headers
• A06 Vulnerable and Outdated Components - known-CVE libraries and supply-chain risks
• A07 Identification and Authentication Failures - broken auth, weak MFA, session fixation, credential stuffing
• A08 Software and Data Integrity Failures - insecure deserialization, unsigned updates, CI/CD risks
• A09 Security Logging and Monitoring Failures
• A10 Server-Side Request Forgery (SSRF)

Plus client-side risks: Cross-Site Scripting (XSS - reflected, stored, DOM), CSRF, clickjacking, prototype pollution, and DOM-based open redirects.

Our web application penetration testing can be hired individually or together:

• Authenticated and unauthenticated (black-box, grey-box and white-box) web app pentest
• API penetration testing (REST, GraphQL, SOAP, gRPC) aligned with OWASP API Security Top 10
• Source-code-assisted web app review of security-critical components
• AWS cloud and configuration security review of the supporting backend
• Single-page application (SPA) and modern framework testing (React, Angular, Vue, Next.js)
• LLM and AI feature security testing for AI-powered web apps

Average duration is 5 to 25 person-days, depending on application size and complexity.

You will receive a detailed report from a motivated adversary's perspective, with countermeasures to remediate the issues:

• Executive summary explaining issues, attack scenarios and business impact in non-technical language
• Vulnerability descriptions, attack demonstrations and remediation guidance
• Remediation prioritization matrix
• Mapping of findings to OWASP Top 10, OWASP ASVS levels and the relevant compliance framework (SOC 2, ISO 27001, PCI DSS)
• Signed letter of attestation suitable for auditors and enterprise vendor security questionnaires
• Free re-test if performed within 90 days from the final report

Reports arrive within five business days of assessment completion. The same web application penetration testing report supports vendor risk assessments and compliance audits including SOC 2, ISO 27001, PCI DSS 4.0, HIPAA, GDPR and CCPA/CPRA.
