Penetration Testing From People Who Find Real Vulnerabilities in Production Systems
Pentestwell runs offensive security engagements for fintech, SaaS, and enterprise teams in the US, UK, and Pakistan. We cover web and API penetration testing, mobile application security testing, Active Directory and internal network assessments, cloud configuration review, and a specialty most firms don't offer at depth: identity verification (KYC), biometric liveness, and SSO/authentication security testing.
Our lead consultant holds 5 assigned CVEs from independent research and is ranked Top 4 in Pakistan on HackerOne's public leaderboard.
Identity Verification, Biometric Liveness, and SSO Penetration Testing, Under-Tested by Most Vendors
Most VAPT vendors scope to OWASP Top 10 and stop. That's necessary, not sufficient. The highest-impact vulnerabilities we've found in the last two years haven't been in injection or XSS. They've been in the systems that decide whether an entity is who it claims to be.
Identity Verification & KYC Bypass Testing
- →Liveness detection bypass: printed photo attacks, screen replay, video injection, synthetic media presentation attacks
- →Document verification bypass: template forgery, MRZ/OCR manipulation, metadata inconsistency
- →Biometric injection: virtual camera driver injection, API-level bypass of client-side capture
- →Onboarding logic abuse: step-sequence manipulation, race conditions, session/token reuse across verification steps
SSO & Authentication Testing
- →SAML: XML signature wrapping, assertion replay, missing audience restriction validation
- →OAuth2/OIDC: redirect_uri bypass, PKCE downgrade, state parameter omission, scope escalation
- →JWT: algorithm confusion, kid header injection, weak signing key brute-force
- →Session management: fixation, hijacking, insufficient invalidation
- →MFA: fallback abuse, backup code enumeration, OTP rate-limit gaps
- →Federation trust: IdP impersonation, cross-tenant token confusion
Full-Scope Offensive Security Testing
Web Application Penetration Testing
Manual testing to OWASP ASVS Level 2/3: IDOR/BOLA, business logic abuse, SSRF, access control failures. Every finding ships with a reproducible proof-of-concept.
API Penetration Testing
REST and GraphQL testing against the OWASP API Security Top 10: BOLA, BFLA, mass assignment, resource-consumption abuse.
Mobile App Penetration Testing
Android and iOS, static and dynamic: insecure storage, certificate pinning bypass, IPC vulnerabilities, reverse-engineering resistance.
Active Directory & Network Pentesting
Post-compromise simulation: Kerberoasting, ACL abuse, NTLM relay, delegation abuse, domain privilege escalation.
Cloud Security Assessment
AWS/Azure/GCP: IAM privilege escalation paths, exposed storage, IMDS credential theft, over-permissioned serverless roles.
Vulnerability Assessments
Authenticated/unauthenticated scanning with manual validation. One-time or recurring, for SOC 2, PCI DSS, or ISO 27001 coverage.
How We Run an Engagement
Reports are structured to be usable as evidence for SOC 2 Type II, PCI DSS, and ISO 27001 audits.
Scoping & threat modeling
Attack surface and abuse cases specific to your architecture.
Reconnaissance & enumeration
Passive and active surface mapping before exploitation.
Manual vulnerability discovery
Tooling (Burp Suite, Nmap, BloodHound) supports the work, doesn't replace it.
Exploitation & chaining
Impact validated through exploitation, not just flagged.
Reporting
CVSS-scored findings, proof-of-concept evidence, actionable remediation guidance.
Debrief
Live walkthrough with your security and engineering leads.
Remediation validation
Free retest of critical/high findings post-fix.
Why Senior Teams Choose Us Over a Bigger Vendor
Larger firms staff engagements based on bench availability. You may not know who's actually testing your systems until the kickoff call. We don't have a bench.
Every engagement is led by a consultant with independent CVE research and bug bounty experience finding vulnerabilities in production systems at scale, not just in lab environments. That matters, because attackers don't follow a checklist either.

Send us your architecture at a high level and we'll tell you, specifically, what we'd test, what techniques we'd apply, and what it costs, before you commit to anything.
