Securing VoIP against SIP header manipulation and setting up bulletproof VPNs needs careful attention because standard configs leak data easily. I have spent years handling OSINT gathering and testing advanced malware evasion techniques so I know exactly how threat actors exploit these setups. You will get a complete security posture without needing to hire separate guys for network and malware analysis. We will start by mapping your PBX and testing your current setup against spoofed traffic to see what gets through. I will provide a clear word document outlining your exact vulnerabilities and the immediate fixes needed before we even dive deep into the red teaming phase. My workflow covers everything from ethical threat emulation to hardening so your entire infrastructure stays secure. We will execute the NDA today and I will start mapping the infrastructure immediately. Lets do it.

I’ve worked on securing VoIP and VPN infrastructures where misconfiguration directly translated into financial and operational risk. I handle SIP hardening (TLS/SRTP), PBX exposure reduction, anti-spoofing controls, firewall rule tuning, and anomaly detection at the signaling and traffic level. For VPN environments, I implement hardened deployments, enforce strong authentication, test for DNS/IP leaks, and simulate lateral movement scenarios to validate real-world resilience. On the offensive testing side, I conduct controlled spoofing validation, malware analysis (static and dynamic), packet-level inspection using tools like Wireshark, and structured threat emulation for defensive tuning. My approach is disciplined and evidence-driven — every test produces documented findings, risk severity mapping, and actionable remediation steps. I work strictly within ethical and NDA-bound environments. Given the confidentiality and short-term nature of your project, I can commit immediately, provide structured weekly reporting, and focus on measurable security improvements rather than theoretical assessments. If you’re looking for someone who can operate independently while maintaining research discipline, I’m ready to begin.
