6+ years as a Security Researcher, CEH v12 and ISO 27001 Certified Lead Security Auditor, I help startups, SaaS companies, and enterprises secure everything they build and run from a single web app to multi-cloud infrastructure, AI/ML systems, and full compliance programs. My approach is simple: security isn't a scanner dump, it's a clear view of your real risk plus a prioritized, actionable plan to fix it. Coming from a strong software engineering background, I read source code, follow data flows, and reason about architecture, so I catch the business-logic and design flaws that automated tools always miss. 🌐 APPLICATION SECURITY & PENETRATION TESTING Full-stack web, mobile, and API pentesting across the OWASP Top 10 & API Security Top 10: broken access control, IDOR, SSRF, injection (SQL/NoSQL/command/template), XSS, CSRF, insecure deserialization, auth/session flaws, and business-logic abuse. Apps built on React, Angular, Vue, Next.js, Node.js, Python (Django/Flask/FastAPI), Java (Spring), PHP (Laravel), Ruby on Rails, .NET, and Go, plus Android/iOS (OWASP MASVS). Every finding is manually verified to remove false positives, CVSS-scored, and shipped with developer-ready remediation and a free retest. Tools: Burp Suite Pro, OWASP ZAP, Nmap, Metasploit, Nuclei, sqlmap, Nessus, ffuf. ☁️ CLOUD SECURITY ( AWS, AZURE & GCP) IAM and least-privilege reviews, network segmentation (VPC/VNet, security groups, NACLs), encryption/KMS, logging and monitoring (CloudTrail, GuardDuty, Azure Defender, GCP Security Command Center), and CIS Benchmark hardening aligned to Well-Architected security pillars. I find misconfigurations, exposed storage (S3/Blob/GCS), over-permissive roles, and privilege-escalation paths, and design secure cloud architectures with CSPM tools like Prowler and ScoutSuite. ⚙️ DEVSECOPS & INFRASTRUCTURE SECURITY Security built into CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, CircleCI, Azure DevOps), container and Kubernetes security (image scanning with Trivy/Grype, RBAC, network policies, Pod Security Standards), and Infrastructure-as-Code review for Terraform, CloudFormation, Ansible, and Pulumi (Checkov, tfsec, Terrascan). I integrate SAST, DAST, SCA, and secrets scanning (Semgrep, Snyk, SonarQube, Gitleaks, TruffleHog) into automated pipelines, with secrets management via HashiCorp Vault, AWS Secrets Manager, and cloud KMS securing the full software supply chain from commit to deploy. 🤖 AI / ML SECURITY I secure AI, ML, and LLM-powered features against the OWASP Top 10 for LLM Applications and the MITRE ATLAS framework: prompt injection, jailbreaks, sensitive-data and training-data leakage, insecure output handling, model denial-of-service, supply-chain risks, and excessive agency in autonomous/agentic systems. I review apps using OpenAI, Anthropic Claude, and open-source models (Llama, Mistral), plus RAG pipelines, vector databases, TensorFlow, and PyTorch and leverage AI defensively for security automation and faster threat detection. 📋 GOVERNANCE, RISK & COMPLIANCE (GRC) As an ISO 27001 Lead Auditor, I lead ISO 27001:2022 implementation, internal audits, gap analysis, ISMS development, Statement of Applicability, and risk treatment plans to get you certification-ready. I also support SOC 2 (Type I & II), GDPR, HIPAA, PCI-DSS, and NIST Cybersecurity Framework alignment, including security policies, risk registers, vendor/third-party risk management, awareness training, and audit-ready documentation. 🧠 SECURITY ENGINEERING & RESEARCH Secure code review across multiple languages, threat modeling (STRIDE, attack trees), reverse engineering (including Java/bytecode and anti-tamper analysis), malware analysis fundamentals, network security, and security architecture design. I also build cybersecurity training programs and translate complex risk into language both executives and developers understand. 🤝 HOW I WORK 1️⃣ Free scoping call to understand your stack, goals, and concerns 2️⃣ Testing/assessment with clear, regular communication 3️⃣ A prioritized report - Executive Summary + technical detail + exact fixes 4️⃣ A free retest and debrief once your team remediates Every engagement is handled with strict confidentiality and full authorization. I don't oversell if you don't need a service, I'll tell you honestly. 📩 Message me with a few details about your project and I'll reply with practical, no-pressure next steps.

What if your systems aren’t as secure as you think they are? Hi, I’m Dhabaleshwar, a certified ethical hacker (CEH) and I’ve spent 5+ years digging into the hidden cracks of some of the most complex systems. It’s not just a job—it’s a mission. I’ve discovered vulnerabilities that others missed, cracked open security layers thought to be impenetrable, and saved businesses from potential disasters. Imagine this: A global enterprise hires me after passing every standard penetration test. They feel confident, but something isn’t adding up. In just days, I find a zero-day vulnerability buried deep in their infrastructure—one that could have cost them millions. That’s the kind of impact I deliver. I’ve completed 400+ penetration tests, discovered over 300 zero-day vulnerabilities, and earned a spot among India’s Top 15 Security Researchers in 2023. But what really sets me apart is my approach: I don’t just find vulnerabilities—I show you exactly how they can be exploited, how they can harm your business, and, most importantly, how to fix them. What I Do Best 1- Thick Client Pentesting: I thrive in environments where others hesitate—proprietary protocols, layered logic, and thick client applications that demand a unique skill set. 2- API Security: REST, SOAP, GraphQL—you name it. I expose broken access controls, privilege escalation flaws, and injection vulnerabilities that others overlook. 3- Web & Mobile Applications Pentesting: From XSS and SSRF to insecure deserialization, I break down your app’s defenses, ensuring its resilience from the inside out. 4- Cloud & Container Security: AWS, GCP, Kubernetes, Docker—I don’t just find gaps; I close them. 5- LLM Pentesting: Language models like ChatGPT and other AI systems are powerful but vulnerable. I test for prompt injection, unauthorized data leakage, and logic bypasses, ensuring your AI solutions are both functional and secure. 6- Red Teaming: Want to see how your defenses stand up to real-world attackers? I simulate advanced adversarial tactics, probing for weaknesses in your people, processes, and technologies. 7- Custom Exploitation: When security gets tough, I get creative—crafting tailored attack scenarios that demonstrate real-world impact. Why Clients Work With Me When businesses work with me, they’re not just ticking boxes—they’re securing their future. Clients trust me to: i) Think Like an Attacker: I approach systems like someone trying to break in. No assumption is too small, no layer too secure. ii) Prove the Impact: For every vulnerability I find, I provide actionable evidence—step-by-step scenarios, proof-of-concept exploits, and recommendations to fortify your defenses. iii) Deliver Results That Matter: My detailed reports go beyond technical jargon. They tell you what’s wrong, why it matters, and exactly how to fix it. Key Achievements - 400+ Penetration Tests: From enterprise platforms to government systems, I’ve safeguarded industries against real-world threats. - 300+ Zero-Days Discovered: From RCE to SQLi, XSS, BAC etc. I’ve found and fixed vulnerabilities that could have caused serious harm, keeping businesses safe from real threats. - India’s Top 15 Security Researchers (2023): Recognized for uncovering 200+ vulnerabilities in critical government systems. Tools & Methodologies I leverage a wide range of tools, including Burp Suite Pro, Postman, Metasploit, Nmap, OWASP ZAP, Wireshark, Nessus, Acunetix etc. to uncover vulnerabilities with precision. For advanced needs, I write custom scripts in Python, Bash, and Java, ensuring a tailored approach. In LLM Pentesting, I use techniques like prompt engineering and adversarial logic testing, while Red Team engagements involve tools like Cobalt Strike, BloodHound, and Empire to simulate real-world threats. Client Testimonials "We thought our applications were secure—until Dhabaleshwar exposed what others missed. His insights have been invaluable."
