Securing what matters with expert cybersecurity, clear communication, and trusted solutions.

Hi, I'm Muhammad Haris Sultan, a cybersecurity enthusiast and freelance consultant dedicated to helping businesses, developers, and startups secure their websites and applications. With practical experience in manual vulnerability testing, I specialize in identifying and reporting real-world security risks in web environments.

I offer deep analysis of web apps using a combination of manual testing and proven security methodologies. My goal is not just to run automated scans, but to find vulnerabilities that actually matter. From XSS and SQL injection to IDOR, misconfigurations, exposed APIs, CORS issues, authentication flaws, and access control problems, I work carefully to detect and document what others might miss.

I use tools like Burp Suite, FFUF, subfinder, gau, Param Miner, and others, but my real strength is in manually exploring request flows, analyzing hidden endpoints, and thinking like an attacker. I gained hands-on experience through platforms like 101 CTF, PortSwigger Web Academy, and live testing on Bugcrowd and private programs. These platforms allowed me to develop the same skills used by real-world bug bounty hunters, but with a focus on ethical and responsible testing.

When you work with me, you're not just hiring someone to press a button and send a confusing report. I provide detailed, organized vulnerability reports with plain-English explanations, technical impact, and step-by-step guidance on how to fix each issue. Whether you are a developer needing help to secure your API or a business owner looking to reduce risk before launch, I adapt to your needs and deliver with clarity and focus.

My approach is client-first. I take time to understand what you're building and what your goals are, so I can tailor my testing accordingly. You can expect honesty, professionalism, and timely communication throughout the process.

I believe in continuous growth and learning. Every day, I study new techniques, explore bug bounty writeups, and challenge myself with new labs. I value long-term working relationships and aim to deliver work that is valuable, understandable, and useful.

Outside of work, I enjoy studying cybersecurity case studies, exploring new tools, and practicing on cybersecurity platforms. I also love driving across the scenic roads of Punjab, helping small businesses with online strategy, and sharing what I learn to help others grow in freelancing and security.

If you are looking for someone who takes your security seriously, communicates clearly, and works with dedication, I would love to work with you. Let’s connect and make your platform safer and stronger.
