Independent offensive security and VAPT engineering.
esecnet is a specialized cybersecurity agency focused on Vulnerability Assessment and Penetration Testing (VAPT). We work with engineering, infrastructure, and security teams to uncover exploitable security flaws before they are used in an attack.
Rather than relying solely on automated vulnerability scanners, our assessments pair systematic baseline discovery with human-led penetration testing across web applications, backend APIs, Android and iOS mobile apps, AI and LLM systems, enterprise networks, servers, cloud platforms, and desktop thick clients.
Practice overview
- Core discipline
- Vulnerability Assessment (VA) and Manual Penetration Testing (PT)
- Seven testing practices
- Web Applications, APIs (REST, GraphQL, gRPC), Mobile Apps (Android & iOS), AI & LLM Systems, Network Infrastructure, Servers / Active Directory / Cloud, and Thick Client Software
- Testing models
- Black-Box (unauthenticated external), Grey-Box (authenticated role and schema testing), and White-Box (source code and configuration review)
- Compliance support
- Audit-ready VAPT reports and re-test verification for SOC 2, ISO/IEC 27001, PCI-DSS, HIPAA, and enterprise customer security reviews

Why automated scanning alone is not enough
Automated vulnerability scanners are useful for identifying outdated software packages, known CVEs, and missing security headers. However, scanners cannot understand how your application handles multi-tenant permissions, financial workflows, or API state transitions.
What conventional scanner-only audits miss
A purely automated scan treats every application the same. It checks surface responses against static signatures without understanding your business rules or architecture.
- Cannot detect Broken Object Level Authorization (BOLA / IDOR) between different customer accounts
- Misses multi-step business logic bypasses in checkout, billing, or privilege approval flows
- Cannot chain a low-severity information leak with an API or cloud IAM misconfiguration
- Often produces long unverified PDF exports containing false positives that slow down engineering teams
How esecnet conducts VA + PT
We use automated scanning as the starting baseline, then dedicate the core of the engagement to manual offensive testing by specialist engineers.
- Manual role-matrix testing across privilege levels, tenants, and API endpoints
- Controlled exploitation and attack chaining to demonstrate real-world business impact
- Manual verification of every finding so your developers only receive confirmed, reproducible issues
- Concrete code and configuration remediation guidance followed by patch verification retesting
Engagement governance and operating principles
Penetration testing requires high trust. Every esecnet engagement follows strict operational controls to protect system availability and sensitive data.
Written Rules of Engagement (RoE)
Before any assessment begins, we establish a formal Rules of Engagement document with your team. This defines exact in-scope URLs, IP ranges, mobile builds, excluded environments, authorized testing windows, rate limits, source IP addresses for firewall allowlisting, and emergency points of contact.
Verified findings with reproducible proofs
We never deliver raw scanner dumps. Every vulnerability included in an esecnet report is manually validated by an engineer and documented with clear reproduction steps, HTTP or API request/response traces, and screenshots so your developers can reproduce the issue immediately.
Data confidentiality and ephemeral environments
All engagements operate under a mutual Non-Disclosure Agreement (NDA). Testing is conducted from isolated environments, assessment reports are delivered over encrypted channels, and all logs, binary artifacts, and captured evidence are permanently purged after engagement completion.
Direct engineering collaboration and retesting
Our goal is helped remediation, not just finding bugs. If we uncover a critical vulnerability during testing, we notify your team immediately rather than waiting for the final report. Once fixes are deployed, we re-test every finding to confirm the vulnerability is closed.
What your team receives at the end of an engagement
Our reporting is structured for two distinct audiences: clear risk and compliance documentation for leadership and auditors, and detailed technical evidence for software and infrastructure engineers.
Executive & Compliance Summary
A concise overview written for security leadership, enterprise customers, and external auditors. Documents the tested scope, methodology, overall security posture, severity distribution, and alignment with SOC 2, ISO 27001, PCI-DSS, or HIPAA requirements.
Technical Vulnerability & PoC Report
An engineering-focused report detailing each confirmed finding: CVSS severity score, OWASP or CWE classification, affected endpoints or components, step-by-step proof-of-concept payloads, business impact analysis, and concrete code or configuration remediation recommendations.
Remediation Verification Report
After your engineering team patches the identified vulnerabilities, we perform verification retesting on the updated build or environment and issue an updated report confirming the remediation status of every finding.
Standards and methodologies across our seven VAPT practices
We align every assessment with established security testing benchmarks tailored to the target technology stack.
| VAPT Practice | Primary Standards & Benchmarks | Core Assessment Focus |
|---|---|---|
| Web Application Pentesting | OWASP WSTG v4.2, OWASP Top 10, OWASP ASVS | Authentication, session management, multi-tenant access control (IDOR), injection flaws, XSS, SSRF, and business logic |
| API Penetration Testing | OWASP API Security Top 10 (2023) | REST, GraphQL, gRPC, and WebSockets; BOLA, BOPLA (mass assignment), JWT validation, and rate limiting |
| Mobile App Pentesting (Android & iOS) | OWASP MASVS v2.0, OWASP MASTG | APK and IPA reverse engineering, Keystore/Keychain storage, SSL pinning, Frida runtime instrumentation, and mobile APIs |
| AI & LLM Penetration Testing | OWASP Top 10 for LLM Apps (2025), MITRE ATLAS | Direct and indirect prompt injection, RAG vector database access controls, system prompt isolation, and agent tool permissions |
| Network & Infrastructure Pentesting | PTES, NIST SP 800-115 | External perimeters, routers, switches, firewall rule auditing, VPN gateways, and internal VLAN segmentation |
| Server, Active Directory & Cloud Pentesting | CIS Benchmarks, MITRE ATT&CK Enterprise | Linux and Windows server hardening, Active Directory attack paths (Kerberos, ADCS, GPOs), and AWS, Azure, and GCP IAM |
