Testing & Assurance / Web Application Testing

Your web apps are
your largest exposed
attack surface.

Web applications are the primary target in the majority of data breaches. Cliffside's web application security testing goes beyond automated scanning to manually assess authentication, session management, business logic, and the vulnerabilities that automated tools consistently miss.

OWASP Top 10 and beyond.

Our testing methodology is aligned to OWASP and PTES standards, but goes further — including business logic testing, API security assessment, and the application-specific vulnerabilities that generic frameworks miss.

Injection attacks

SQL, NoSQL, OS command, LDAP injection — and newer techniques like GraphQL injection.

Authentication & session management

Weak authentication, session fixation, token predictability, and credential exposure.

Access control

Broken object level authorisation, function-level access control, and privilege escalation.

Business logic flaws

Workflow bypasses, race conditions, and application-specific vulnerabilities that only humans find.

API security

REST, GraphQL, and SOAP API assessment — covering authentication, rate limiting, and data exposure.

XSS & client-side attacks

Stored, reflected, and DOM-based cross-site scripting — and the impact chain that follows.

Security misconfiguration

Default credentials, unnecessary features, missing security headers, and cloud misconfigurations.

Sensitive data exposure

Unencrypted transmission, insecure storage, and unintended data leakage in API responses.

Third-party components

Known vulnerabilities in libraries, frameworks, and dependencies — with exploitability assessment.

Automated scanners miss the most dangerous vulnerabilities.

Automated web application scanners are useful tools — but they're not a substitute for skilled manual testing. Business logic flaws, privilege escalation chains, and the vulnerabilities that arise from the interaction between application components require human expertise to find.

Cliffside's testers bring real-world application security experience. They understand how web applications are built, how they're attacked, and how to chain low-severity findings into high-impact exploit paths — the way real attackers do.

scanners always miss.
