Vulnerability Assessment & Penetration Testing
OSCP & CPTS-certified testers find what scanners miss. Detailed reports with proof-of-concept in 1–3 weeks, free retesting included.
Our testers hold industry-recognized offensive security certifications
CPTS Certified 
OSCP Certified What We Test
Comprehensive security testing across your entire attack surface — from web applications to cloud infrastructure.
Web Application Testing
OWASP Top 10 coverage, authentication bypass, session management, business logic flaws. We test like real attackers think.
Network Penetration Testing
External and internal assessments, firewall testing, segmentation validation, lateral movement, and Active Directory review.
API Security Testing
REST and GraphQL testing, authentication flaws, authorization bypass, rate limiting, and data exposure in your endpoints.
Mobile Application Testing
iOS and Android security — local data storage, certificate pinning, reverse engineering protection, and backend API calls.
Cloud Security Assessment
AWS, Azure, and GCP configuration review, IAM policy analysis, storage security, serverless testing, and infrastructure hardening.
Wireless & Social Engineering
Wi-Fi security audits, rogue AP detection, phishing simulations, physical security testing, and employee awareness validation.

Why Choose Underwings
Certified Testers, Not Scanner Jockeys
Our team holds OSCP and CPTS certifications — we manually test like real attackers, going beyond automated scan-and-dump reports.
Honest, Transparent Pricing
We're a startup too, so we get it. Scope-based pricing, no hidden fees, no enterprise markups. Quality testing that fits real budgets.
Fast Turnaround
Most engagements completed in 1–3 weeks with a detailed report. No months-long queues — we move at your pace.
Free Retesting Included
We retest all findings after remediation at no extra cost. You only pay once — we stay until it's fixed.
Comprehensive Deliverables
Technical Report
Detailed write-up of every vulnerability with severity ratings, proof-of-concept screenshots, and reproduction steps — not a generic scanner dump.
Free Retesting
After you fix the findings, we retest every vulnerability at no extra cost. You get a clean verification report confirming the fixes are solid.
Executive Summary
Non-technical overview with risk posture, key findings, and strategic recommendations for leadership and stakeholders.
Risk Ratings & Prioritisation
Every finding scored with CVSS, mapped to business impact, and prioritised so your team knows exactly what to fix first.
Remediation Guidance
Step-by-step fix instructions with code snippets and configuration examples — not just "patch your software".
Debrief Session
Live walkthrough with your dev and security team to discuss findings, answer questions, and align on remediation strategy.
Frequently Asked Questions
What is the difference between Vulnerability Assessment and Penetration Testing?
A Vulnerability Assessment identifies and catalogues security weaknesses using automated tools and manual checks. Penetration Testing goes further — our testers actively exploit vulnerabilities to demonstrate real-world impact, chaining findings like an actual attacker would.
How long does a typical VAPT engagement take?
Most assessments take 1–3 weeks depending on scope. A single web application typically takes 5–10 business days. We provide a clear timeline during the free scoping call.
Do you offer free retesting?
Yes. After you remediate the findings, we retest all identified vulnerabilities at no extra cost to confirm they are properly fixed.
What standards and frameworks do you follow?
We follow OWASP Testing Guide, PTES (Penetration Testing Execution Standard), and NIST SP 800-115. Our reports map findings to relevant compliance requirements like PCI DSS, ISO 27001, and SOC 2.
Will the testing disrupt our production systems?
We take a careful, controlled approach. Testing is scoped and scheduled with your team, and we avoid destructive tests unless explicitly authorised in a staging environment.
