// ai security code reviewer
Review code with evidence and context
Submit a focused code or configuration snippet and receive a defensive static review with prioritized findings, CWE references, and practical remediation guidance. Source is never executed by this page.
// defensive review coverage
What the assessment looks for
SQL, command, template, and code-execution paths influenced by untrusted input.
Missing ownership checks, weak session handling, and broken access-control assumptions.
Hardcoded credentials, weak primitives, predictable tokens, and unsafe key handling.
SSRF, path traversal, unsafe deserialization, XSS, and disabled TLS verification.
Frequently asked questions
What kinds of vulnerabilities does it find?
It flags common classes such as injection, insecure deserialization, hardcoded secrets, weak cryptography, missing input validation, and unsafe configuration, with severity and remediation guidance.
Which languages are supported?
It reviews mainstream languages by reasoning over the submitted snippet. Results are strongest for self-contained functions and clearly scoped files.
Is my code stored?
No. Code is analyzed for the request and is not retained by this page. Avoid submitting production secrets, personal data, customer records, or regulated information.
Does it replace a full security audit?
No. It is a first-pass defensive review. Pair it with dependency scanning, tests, runtime analysis, secure design review, and qualified human review for production systems.
How your input is handled
Processing
Pasted code is reviewed for this one request. NeoShield does not store your source, and no snippet is retained after the response is rendered. The material you submit is sent to the AI provider for this one analysis and is not used to train models.
What we never keep
- Offline analyzer input is not stored or logged.
- No model-authored code is executed on NeoShield servers.
- Credentials, tokens, and payloads you paste are never written to disk by these tools.

What this tool does — and does not — check
It checks
- Injection classes: SQL, command, template, and unsafe deserialization.
- Broken authentication and authorization logic, including missing ownership checks.
- Hard-coded secrets, API keys, and credentials committed into source.
- Weak cryptography and predictable randomness (CWE-327 / CWE-330).
- SSRF, path traversal, and disabled TLS verification.
It does not check
- It does not execute your code; analysis is static.
- It does not resolve imports or analyze code you did not paste.
- It does not replace a full SAST pipeline or manual code audit.
- It cannot prove code is free of vulnerabilities; absence of findings is not assurance.
How it works
- The snippet is sent to an AI reviewer prompt scoped to defensive analysis and mapped to CWE classes.
- Findings are returned with severity, relevant line context where available, and remediation guidance.
- Model output is treated as untrusted data, displayed for human review, and never executed on NeoShield servers.
