Offensive Security &
Penetration Testing
We simulate real-world adversaries across applications, infrastructure, and human layers to uncover critical vulnerabilities before they are exploited.
The Difference Between a Compliance Checkbox and a Genuine Adversary Simulation
Operator-Grade Expertise
Our offensive security team holds OSCP, OSCE3, CRTO, CRTE, eCPTX, and PNPT certifications. These are hands-on, examination-based credentials that cannot be earned through multiple-choice tests — they require real exploitation under pressure.
No Automation Theatre
Automated vulnerability scanners find known CVEs. Our testers find the logic flaws, authentication bypasses, and chained attack paths that no scanner can detect — because they require human creativity and adversarial thinking.
Full Legal & Ethical Framework
Every engagement is governed by a formal Rules of Engagement (RoE) document, written authorisation, defined scope boundaries, and a structured communication protocol. Your legal and compliance teams will have everything they need.
Board-Ready Reporting
Our deliverables include two reports: a detailed technical report for your security and engineering teams with PoC evidence and remediation steps, and an executive summary for leadership and the board — in plain business language.
Six Specialised Capabilities
One integrated adversarial testing practice. We go beyond automated scanners.
Web & API Penetration Testing
Deep logic flaw discovery that goes far beyond automated scanners — complex business logic abuse, authentication bypasses, and chained multi-step attack paths. Covers OWASP Top 10 (Web) and OWASP API Security Top 10 with CVSS 3.1 scoring and PoC evidence.
Mobile App Security Testing
iOS and Android security testing — from binary reverse engineering and runtime manipulation (Frida) to API interception and local storage forensics. Full OWASP MASVS assessment for both platforms.
Network & Infrastructure Pentesting
Internal, external, and network segmentation testing — full attack chain documentation from initial access to domain compromise. Active Directory attack chains, cloud misconfiguration exploitation, and MITRE ATT&CK mapping.
Source Code Security Review
Manual and SAST-assisted review of critical codebases — finding logic flaws, injection vulnerabilities, hardcoded secrets, and insecure patterns. Covers Java, Python, Go, Node.js/TypeScript, PHP, C/C++, Ruby, Swift, Kotlin, and Rust.
Red Team Operations
Full-chain adversary simulations combining physical intrusion, social engineering, and digital attack vectors — testing your people, processes, and technology simultaneously. Cobalt Strike / Sliver C2 with full OPSEC discipline and Purple Team debrief.
Supply Chain Security Audit
Third-party dependency analysis, vendor risk assessment, and open source component review. SBOM generation in CycloneDX and SPDX formats, CI/CD pipeline audit, and dependency confusion exposure assessment.
Our Engagement Process
A structured, repeatable, and legally governed process — from kick-off to remediation validation.
Scoping & RoE
Define objectives, scope boundaries, rules of engagement, and legal authorisation.
Reconnaissance
OSINT, attack surface mapping, and technology fingerprinting.
Exploitation
Active testing — manual and tool-assisted vulnerability exploitation.
Post-Exploitation
Lateral movement, persistence, privilege escalation, and objective achievement.
Reporting
CVSS-scored findings, PoC evidence, executive summary, and technical report.
Remediation Check
Re-test of all findings post-remediation to confirm effective fix.
What You Receive
Actionable intelligence at the conclusion of every ZecurX offensive security engagement.
Technical Report
Detailed finding write-ups with PoC evidence, CVSS 3.1 severity scores, step-by-step reproduction instructions, root cause analysis, prioritised remediation recommendations, and affected asset mapping.
Executive Summary
Risk posture assessment in business language with overall security rating, benchmarking, top 3 critical risks, investment and effort estimates for remediation, and a board-presentation ready format.
Remediation Support
30-day post-report developer Q&A access, secure code fix guidance for each finding, re-test of all remediated vulnerabilities, remediation validation attestation letter, and finding closure tracking dashboard.
Compliance Artifacts
CERT-In / RBI submission-ready summary, formal testing attestations, and documentation satisfying CERT-In Directions 2022, RBI Cyber Security Framework, SEBI CSCRF, SOC 2, ISO 27001, and HIPAA requirements.
Proven adversarial testing outcomes
How our offensive security engagements uncovered critical vulnerabilities before attackers did.
Multi-Tenant Isolation Failure Discovered in B2B SaaS
"ZecurX discovered a chained vulnerability in our admin API — a low-severity info disclosure combined with a BOLA flaw allowed any authenticated user to access all other tenants' data. It hadn't been flagged by any automated tool or our previous vendor."
Critical Fintech API Flaw Found Before Launch
"ZecurX bypassed our certificate pinning with Frida and discovered an undocumented internal API endpoint that accepted transaction approvals without secondary authentication. CVSS 9.8 — patched before the release went live."
Domain Admin in 4 Hours 22 Minutes
"Starting from a standard user workstation, ZecurX achieved Domain Administrator access in under 5 hours — through an unpatched print spooler and a Kerberoastable service account. We had passed our external audit with zero critical findings."
Credential Harvesting Payload Found in Production npm Package
"A deprecated npm package in our auth module had been taken over. ZecurX found obfuscated credential harvesting code auto-updated into our production environment 6 weeks prior. The SBOM let us identify the package within 4 minutes."

Structured to Match Your Risk Appetite
Designed to match your compliance timeline, risk appetite, and internal capability.
Point-in-Time Assessment
Fixed-scope engagement for a specific application, network segment, or source codebase. Ideal for compliance-driven testing cycles, pre-release security validation, and regulatory audit preparation. Deliverables within 5 business days of engagement close.
Continuous Penetration Testing
Monthly or quarterly retainer-based testing aligned to your release cycle. New features and infrastructure changes are tested as they ship — not 12 months later. Includes a dedicated tester familiar with your environment and codebase.
Red Team Retainer
Annual adversary simulation with quarterly assumed-breach exercises and purple team sessions. Continuously validates your detection and response capability as your environment and the threat landscape evolve. Includes tabletop exercise facilitation.
DevSecOps Integration
Embedding ZecurX security engineers into your development sprints — security review at the design stage, code review in pull request workflows, and automated SAST/SCA tooling configuration. Security built in, not bolted on.
Find your vulnerabilities before your adversaries do.
