How do you handle token-based authentication during testing?

Our testers validate JWT and OAuth 2.0 implementations — including token forgery, replay, session invalidation and refresh-token abuse — using test credentials you provide, without disrupting production.

How do you guarantee there are no false positives?

Every AI-detected finding is manually verified by a senior pentester before it reaches your report. This is backed by a contractual zero false positives SLA: if you find a single false positive, you get your money back.

Is retesting included, and what is your retesting SLA?

Yes. Free unlimited retesting is included with every engagement. Once your team applies a fix, we re-verify the affected endpoints at no extra cost so you can prove remediation to auditors and stakeholders.

Pourquoi le test d'intrusion des API est un levier de revenus

Les API transportent désormais la majeure partie du trafic Web moderne — et une part croissante des violations de sécurité actuelles. Une seule faille de Broken Object Level Authorization peut exposer l’intégralité de votre base de données clients, entraîner des amendes réglementaires et bloquer chaque contrat d’entreprise en attente de validation de sécurité. Considérer les tests d’intrusion API comme un levier de revenus — et non comme une taxe de conformité — raccourcit les cycles de vente, protège les revenus récurrents et transforme votre posture de sécurité en avantage concurrentiel.

Automated API Scanning vs Manual Penetration Testing

	Automated API Scanning	Test d'intrusion manuel d'API
Duration	Minutes to hours, on every commit	A few days, scheduled per release or audit
Cost	Low, subscription-based	Higher, project-based fixed fee
Champ d'application	Known vulnerability patterns, OWASP signatures	Logique métier, exploits enchaînés, BOLA/BFLA, contournement d'authentification
Idéal pour	Daily CI/CD regression and broad coverage	Audits, compliance, high-risk and pre-launch APIs
Report	Automated list of findings	Validated, manually exploited, remediation-ready report

Recommendation: Automated scanning is essential for daily CI/CD hygiene and catching regressions fast. But for audits, compliance sign-off, and APIs handling sensitive data, manual penetration testing is mandatory — only a human tester can chain logic flaws into a real exploit. ImmuniWeb® On-Demand combines both: AI-driven coverage plus senior pentester validation in a single engagement.

Portée complète des tests d’architecture et de sécurité des API

Every engagement covers your full API surface — documented and undocumented. Upload an OpenAPI/Swagger, Postman or GraphQL schema and our hybrid team tests across four dimensions:

Endpoint Discovery & Functional Coverage

Découverte des APIs fantômes et zombies au-delà de votre schéma documenté
Énumération des points de terminaison REST, GraphQL, gRPC, SOAP et WebSockets
OpenAPI / Swagger and Postman collection parsing for full coverage
Deprecated and undocumented version detection

Authentication, Identity & Access Control

JWT and OAuth 2.0 validation: token forgery and replay testing
Session invalidation, refresh-token and logout flow testing
BOLA (Broken Object Level Authorization) and BFLA exploitation
Privilege escalation and horizontal / vertical access-control bypass

Data Security & Business Logic Integrity

Mass assignment and excessive data exposure testing
Input validation, injection and parameter tampering
Abus de la logique métier, contournement des workflows et conditions de concurrence
Sensitive data leakage in responses, errors and logs

Infrastructure, Gateways & Standards Alignment

Rate-limiting, throttling and resource-exhaustion testing
CORS and CSP misconfiguration analysis
API gateway, WAF and TLS configuration review
Alignment with OWASP API Security Top 10 and SANS Top 25

OWASP API Security Top 10 Vulnerability Mapping

API1 Broken Object Level Authorization (BOLA)

We test every endpoint for object-ID manipulation that lets one user reach another user's data.

API2Authentification cassée

We probe token handling, JWT/OAuth flaws and credential-stuffing exposure.

API3Autorisation au niveau des propriétés de l'objet brisée

We check for mass assignment and excessive data exposure in API responses.

API4Consommation illimitée des ressources

We stress rate limits and quotas to surface DoS and cost-amplification risks.

API5 Broken Function Level Authorization (BFLA)

We attempt to invoke admin and privileged functions as a low-privilege user.

API6Accès illimité aux flux métier sensibles

Nous modélisons l’exploitation abusive de flux tels que le paiement, l’inscription et les virements de fonds.

API7 Server-Side Request Forgery (SSRF)

We test whether user-supplied URLs can pivot into your internal network.

API8Mauvaise configuration sécurité

We review headers, CORS, TLS and gateway settings for exploitable gaps.

API9Gestion inadéquate de l’inventaire

We hunt shadow, zombie and deprecated APIs that widen your attack surface.

API10Consommation non sécurisée des API

We assess how your services trust and process data from third-party APIs.

The 6-Phase API Security Attack Narrative & Kill Chain

Scoping & Schema Onboarding

We define scope and ingest your OpenAPI/Swagger, Postman or GraphQL schema. Artifact: an OpenAPI gap analysis flagging undocumented and risky endpoints.

Phase 1

Phase 2

Passive OSINT & Reconnaissance

We map your exposed API footprint, leaked keys and shadow endpoints from open sources. Artifact: an attack-surface reconnaissance summary.

Automated Vulnerability Scanning & Validation

Our AI engine scans the full surface and analysts validate every finding. Artifact: a verified, false-positive-free vulnerability shortlist

Phase 3

Phase 4

Manual Adversary Exploitation

Senior pentesters chain logic flaws — BOLA, BFLA, auth bypass — into real exploits. Artifact: code-level remediation hints with proof-of-concept.

Audit-Ready Reporting & Debrief

You receive a board- and auditor-ready report plus a live technical debrief. Artifact: full pentest report mapped to OWASP and compliance frameworks.

Phase 5

Phase 6

Continuous Retesting & VAPT Certification

We verify every fix with free unlimited retesting and issue proof of testing. Artifact: a signed compliance / VAPT certificate.

Shift-Left Security: DevSecOps & CI/CD Pipeline Automation

Catch API flaws before they ship. ImmuniWeb® On-Demand plugs natively into GitHub Actions, GitLab CI and Jenkins, turning every pipeline into an automated security gate. Set policy thresholds and vulnerable builds are blocked from deployment automatically — no manual review, no merge of insecure code. Security becomes a pass/fail step in your release, not a quarterly bottleneck, so developers get fast, actionable feedback inside the tools they already use.

Industry-Specific API Threat Modeling

FinTech & Open Banking

Payment-flow and transaction-integrity testing, PSD2 / Open Banking API security, and protection against account takeover and fraud across your money-movement endpoints.

HealthTech & Medical APIs

Tests de confidentialité des données patients et d'exposition des PHI, conformes à HIPAA et GDPR, couvrant les intégrations EHR, les API de télésanté et les flux de consentement.

B2B SaaS & Cloud Platforms

Isolation du multi-locataire et tests de fuites de données locataires — garantissant qu’un client ne puisse jamais accéder aux données d’un autre client au sein de votre infrastructure cloud partagée.

Foire aux questions

Q

Which API architectures and protocols do you test?

A

We test REST, GraphQL, gRPC, SOAP and WebSocket APIs across cloud and on-premise environments. Just upload your OpenAPI/Swagger, Postman or GraphQL schema and we cover documented and undocumented (shadow) endpoints alike.
Q

How do you handle token-based authentication during testing?

A

Our testers validate JWT and OAuth 2.0 implementations — including token forgery, replay, session invalidation and refresh-token abuse — using test credentials you provide, without disrupting production.
Q

How do you guarantee there are no false positives?

A

Chaque constat détecté par l'IA est vérifié manuellement par un pentester senior avant d'être intégré à votre rapport. Cela est soutenu par un SLA contractuel de zéro faux positifs: si vous trouvez un seul faux positif, vous êtes intégralement remboursé.
Q

Is retesting included, and what is your retesting SLA?

A

Yes. Free unlimited retesting is included with every engagement. Once your team applies a fix, we re-verify the affected endpoints at no extra cost so you can prove remediation to auditors and stakeholders.
