Live Code Security

Security code review for teams building in the open

Security vulnerabilities are far cheaper to fix before they reach production. NeedSec works with development teams in real time — reviewing authentication flows, API logic, access control, and security-sensitive changes as they are built. We embed into your workflow to give developer-friendly security guidance that improves code quality without slowing teams down.

Practical assessment

Testing and review work is hands-on and tailored to your environment - not a generic checklist.

Clear, evidence-led output

Every finding includes evidence, business context, and a concrete path to resolution.

Compliance-aware approach

Work is structured around real security improvement - and mapped to relevant frameworks where needed.

What We Assess

Practical testing aligned to business risk

NeedSec combines manual testing, technical validation, and clear reporting so your team understands what matters and how to fix it.

Authentication flow review — login, registration, password reset, and multi-factor implementation

Session management — token storage, expiry, rotation, and invalidation on logout

API authorization and access control — route-level guards, role enforcement, and IDOR risk

Input validation and injection risk — SQL, NoSQL, command injection, and sanitisation gaps

Security-sensitive pull request review — crypto, auth, and data handling changes

Admin and privileged functionality — permission checks, audit logging, and separation of duties

Third-party library security — dependency risk, known CVEs, and API contract review

Secret and credential handling — environment variable usage, hardcoded secrets, and vault patterns

Error handling and information disclosure — stack traces, verbose errors, and debug output

File upload and processing — MIME type validation, path traversal, and malicious file risks

Frontend security — XSS via unsafe rendering, CSP violations, and client-side data exposure

Secure development practices — OWASP SAMM alignment and developer education support

What You Get

Clear deliverables for security, compliance, and remediation

Every engagement concludes with a structured deliverable package so your team can act on findings without guesswork.
