Penetration Testing

What we look for

Web application vulnerabilities we hunt for

Testing follows the OWASP Testing Guide and real attacker behavior, pairing manual exploitation with targeted tooling across the flaw classes that actually lead to breaches.

Injection

Untrusted input reaching an interpreter as a command or query, letting an attacker read, alter, or destroy backend data.

We test for

  • SQL injection
  • OS command injection
  • LDAP and XML (XXE) injection
  • Server-side template injection
  • Input validation and encoding gaps

Broken Access Control & IDOR

Missing or flawed authorization that exposes data and actions meant to be off-limits, including other users records.

We test for

  • Insecure direct object references (IDOR)
  • Horizontal and vertical privilege escalation
  • Forced browsing to hidden functions
  • Parameter and identifier tampering
  • Over-permissive or unprotected endpoints

Broken Authentication & Sessions

Weak identity and session handling that opens the door to account takeover and impersonation.

We test for

  • Weak or default credentials
  • Missing or bypassable MFA
  • Insecure session handling and fixation
  • Password reset and recovery flaws
  • Brute-force and credential-stuffing exposure

Cross-Site Scripting (XSS)

Malicious scripts injected into pages other users load and trust, used to steal sessions or act as the victim.

We test for

  • Reflected XSS
  • Stored XSS
  • DOM-based XSS
  • Unsafe output rendering
  • HTML and JavaScript injection points

Business Logic Abuse

Legitimate features abused in ways the application never intended, often invisible to automated scanners.

We test for

  • Workflow and sequence bypass
  • Price, quantity, and discount manipulation
  • Race conditions
  • Insufficient limits on sensitive actions
  • Abuse of trust between steps

Security Misconfiguration

Insecure defaults, verbose errors, and exposed components that hand attackers an easy foothold.

We test for

  • Default credentials and sample content
  • Verbose errors and stack traces
  • Misconfigured security headers and CORS
  • Exposed admin panels and directories
  • Unpatched components and dependencies

FAQ

Frequently asked questions

What teams most often ask before scoping web application penetration testing.

Still have questions?
01What is the difference between a web application penetration test and a vulnerability scan?

A vulnerability scan uses automated tooling to flag known weaknesses in a web application. A penetration test goes further, showing how well your existing defenses hold up against a real-world attacker who chains those weaknesses together, abuses business logic, and works toward your data the way a cybercriminal actually would.

02How long does a web application penetration test take?

Initial testing for most engagements takes approximately one week. Once we confirm any critical findings, we share them right away alongside an executive presentation of the results and clear remediation guidance. After your team applies the fixes, we run a full retest at no additional cost.

03What does a web application penetration test entail?

Our dedicated security specialists tailor the breadth and depth of testing to your application's architecture and its cloud deployment and service model. We combine automated dynamic analysis with heavy manual testing of the user-facing interface, validating it against the OWASP Top Ten and the wider OWASP Testing Guide to confirm real, exploitable impact rather than theoretical risk.

04Who needs a web application penetration test?

Any organization that relies on a web application to run its business or handle sensitive data. It is an essential tool for confirming that your security controls actually work, and for meeting compliance mandates that apply to your application. Most organizations benefit from testing annually, or twice a year for higher-risk or frequently updated applications.
