About Mr.SIP Pro
Mr.SIP Pro has evolved through over a decade of focused research, open-source innovation, and real-world offensive security practice — delivering the most advanced SIP auditing and attack simulation platforms, purpose-built to simplify complex VoIP security assessments and accelerate secure adoption across all industries.
Built by experts, proven on stage, and refined through real-world challenges.
From Passion Project to Industry-Trusted Platform
First conceived in 2011 as an academic research prototype, Mr.SIP has grown through a decade of continuous refinement — shaped by global conference stages, peer-reviewed publications, and funded R&D initiatives. Today, Mr.SIP Pro is a production-ready toolkit relied upon by red teams, security researchers, and telecom operators worldwide. What began as a research tool is now a production-ready platform relied upon by red teams, security researchers, and telecom operators worldwide.
The original open-source version remains accessible on GitHub, while Mr.SIP Pro extends the platform with advanced modules for SIP fuzzing, deep protocol inspection, tech stack fingerprinting, and exploit simulation based on CVEs.

About the Creator
Mr.SIP Pro is developed under the leadership of Dr. Melih Taş — a cybersecurity researcher, international speaker, and founder of VulnHero and Siber Ninja. His contributions span nearly two decades across VoIP security, application security, and AI/ML-powered security solutions. He authored the national VoIP security strategy in collaboration with TSE (2015), led TÜBİTAK-funded research, taught graduate-level courses, and presented original tools at major conferences like DEF CON and Black Hat.
The project has been independently built and maintained since day one — with every key module, research component, and public demo directly driven by Dr. Taş. While development remains fully owned and led by him, the project has also benefited from occasional operational help and peer feedback from trusted professionals in the security community.
