Hi, I’m Tim Wehrens.
A Network Security Engineer who designs, hardens and maintains cloud and on-prem environments. I help organizations stay resilient against modern threats through Microsoft Azure, zero-trust networking and hands-on security engineering. Welcome to my portfolio.

Engineering security and reliability into every layer of IT.
Ambitious, driven and genuinely curious about how things work. That’s the mindset I bring to every environment I touch. As a Network Security Engineer at SUDO Cybersecurity, I’m deployed across client sites to implement, manage and troubleshoot cloud and security infrastructure, with a focus on Microsoft Azure, identity and network defense.
My path runs from frontline IT support to designing and securing entire network infrastructures. I’ve owned the security of organizational IT at both tactical and operational levels, run vulnerability assessments, remediated risk for customers and managed business-critical applications. I work just as comfortably solo as I do rallying a team toward a shared goal, and I’m always pushing to deepen my expertise.
