I offer world-class penetration testing services and security consultancy at an affordable rate. During my career I have helped clients across AI startups, fintech, e-commerce, logistics, healthcare, social media (Meta), and more – finding vulnerabilities, fortifying defenses, and ensuring compliance (HIPAA, GDPR, NIST, etc.). Services & Expertise - Penetration Testing Services (Web, Network, Cloud): Deep-dive testing to uncover vulnerabilities in your web apps, networks, cloud (AWS, Azure, GCP). I provide clear findings with steps to fix them. - Red Teaming & Adversary Emulation: Simulate real-world cyber attacks to test and improve your organization's readiness. We mimic advanced adversaries to identify gaps in your detection and response. - Generative AI Security & AI Security Consulting: Secure your AI systems (LLMs) from threats like prompt injection and data leaks with specialized generative AI security consulting. - Vulnerability research: Review your application source code to find security flaws and developer friendly guidance on fixing the vulnerabilities. - Cybersecurity & Compliance Consulting (NIST, HIPAA, GDPR, SEC): Guidance to meet security standards and regulations. I help implement controls and best practices to comply with NIST, HIPAA, GDPR, SEC, etc., while improving overall security. - Cloud Security (AWS Security, Azure, GCP): Protection for your cloud infrastructure and DevOps pipeline. Harden servers and configurations and apply best practices. - System Administration & Security Engineering: Secure setup and management of servers, networks, and IT systems. I ensure everything is configured, patched, and monitored according to industry best practices. Why Choose Me? - Security assessments are conducted carefully without interrupting day to day business activities, results are thoroughly validated, zero noise. - Real-time reporting: Findings are reported in real time in a developer-friendly format, making it easy to prioritize and schedule fixes while reducing the window of exposure to potential exploitation. - Clear Communication & Reliability: Expect friendly, prompt communication and total professionalism. I provide regular updates and clear developer friendly reports. Your time and trust are valued, and I deliver on schedule and on budget. - Customized Solutions: No one-size-fits-all. I tailor my services to your specific needs, tech stack, and industry. Whether you need HIPAA compliance for a health app or prepare your app for SOC2 audit, I adapt to deliver the right solution. - Continuous Improvement: I stay on top of emerging threats – from the latest generative AI security issues to new developments in AWS Security – so you always get cutting-edge protection. Please Note (Ethical Hacking Only) I only conduct legal, authorized cybersecurity work.
