Offensive Security & VAPT for Enterprise Systems.

We combine automated Vulnerability Assessment (VA) with manual Penetration Testing (PT) to uncover exploitable security flaws before attackers do.

Our specialist engineers test web applications, backend APIs, Android and iOS mobile apps, AI and LLM pipelines, enterprise networks, Active Directory and cloud environments, and desktop thick clients.

Vulnerability assessment and penetration testing

A complete security assessment requires both broad automated discovery and focused human testing. We combine both disciplines in every engagement.

Vulnerability Assessment (VA)

Automated and configuration-level scanning of your networks, servers, cloud accounts, and applications to identify known CVEs, missing security patches, outdated dependencies, and misconfigurations against CIS and NIST baselines.

Read how we combine VA and PT

Penetration Testing (PT)

Manual ethical hacking performed by security engineers to actively test authentication, authorization boundaries, business logic, and chained attack paths that automated scanners cannot detect.

Web Application Pentesting

Manual testing of web platforms for broken access control, cross-tenant IDOR, injection flaws, session handling issues, and business logic bypasses aligned with OWASP Top 10 and WSTG.

Open Web App VAPT page

API Penetration Testing

Endpoint-by-endpoint testing of REST, GraphQL, gRPC, and WebSocket APIs for object-level authorization flaws (BOLA), mass assignment (BOPLA), token validation errors, and rate-limit bypasses.

Mobile App Pentesting (Android & iOS)

Static binary analysis and dynamic runtime testing of Android (APK/AAB) and iOS (IPA) apps covering insecure local storage, certificate pinning bypass, and backend communication.

Open Mobile VAPT page

AI & LLM Penetration Testing

Adversarial testing of LLM integrations, RAG pipelines, vector databases, and tool-calling agents against direct and indirect prompt injection, data leakage, and excessive agency.

Server, Active Directory & Cloud Pentesting

Security assessments of Linux and Windows servers, Active Directory privilege paths, and AWS, Azure, and GCP cloud identity, storage, and container configurations.

Open Server & Cloud page

Thick Client Application Pentesting

Security testing of enterprise desktop applications built in .NET, Java, C/C++, and Electron, covering reverse engineering, process memory inspection, DLL hijacking, local privilege escalation, and network wire protocols.

How an engagement works

Every engagement follows a clear four-stage structure from scoping through patch verification.

  1. 1. Scoping and Rules of Engagement

    We review your target architecture, define the exact URLs, APIs, mobile binaries, or IP ranges in scope, establish safe testing windows, and sign a mutual NDA and Rules of Engagement document.

  2. 2. Vulnerability Assessment and Manual Testing

    Our engineers run authenticated baseline scans and perform manual penetration testing across roles, workflows, and trust boundaries. Critical findings are reported immediately so your team can begin fixing them early.

  3. 3. Technical Report and Engineering Walkthrough

    You receive a structured report containing an executive summary, CVSS severity ratings, step-by-step reproduction proofs, HTTP or command-line logs, and specific remediation guidance for your developers.

  4. 4. Retesting and Verification Letter

    After your engineering team applies patches, we re-test every reported vulnerability to verify that fixes are complete and issue a final VAPT verification report and attestation letter for your compliance audits.
