What We Test
Comprehensive security testing across every attack surface your business operates on — manual-first, no scanner-only audits.
Mobile App VAPT
Static and dynamic analysis of Android and iOS apps using MobSF and manual testing — covering data storage, network interception, insecure permissions, and reverse engineering.
Cloud Security VAPT
Audit of AWS, Azure, and GCP environments for IAM misconfigurations, exposed storage buckets, container escapes, and privilege escalation paths.
API Security Testing
REST and GraphQL API testing for broken object-level authorization, mass assignment, rate limiting bypass, JWT flaws, and injection vulnerabilities — aligned with OWASP API Top 10.
Network Penetration Testing
Internal and external network assessments using Nmap, Naabu, Nuclei, and Metasploit — covering reconnaissance, exploitation, lateral movement, and post-exploitation.
Security Audit & Reporting
Professional executive and technical reports with CVSS scores, reproducible PoC evidence, prioritized remediation steps, and a re-test to confirm fixes — aligned with ISO 27001 and OWASP.
// methodology
How We Work
A structured, intelligence-driven engagement from scoping to sign-off.

Define assets, rules of engagement, and obtain signed authorization before a single packet is sent.
Reconnaissance
Passive and active OSINT, subdomain enumeration, fingerprinting, and attack surface mapping.
Vulnerability Discovery
Manual testing with Burp Suite, Nuclei, and custom tooling — no scanner-only audits.
Exploitation & PoC
Confirmed, evidence-backed exploitation with CVSS scoring and severity classification.
Reporting
Executive summary + full technical report with reproducible PoC steps and remediation guidance.
Remediation & Re-test
Post-fix re-testing to confirm vulnerabilities are resolved. Patch validation included.
