My name is Martin Plattner. I am an information security professional, software engineer, and consultant based in <a href="https://en.wikipedia.org/wiki/Innsbruck">Innsbruck, Austria</a>. I thrive to work at the intersection of {security, data, people} and develop efficient solutions in this area. I&rsquo;m passionate about learning new things and teaching them to others. </p><p> In my role as lead cyber security consultant at <a href="https://www.axians.at/">Axians ICT Austria</a> I am responsible for developing and executing our <a href="https://www.axians.at/unser-portfolio/cyber-security/">security consulting portfolio</a>, which includes services such as auditing and hardening of large-scale IT infrastructures, simulated phishing, incident response, and other services. I also coordinate our international pentesting and audit team within the Axians Group. </p><p> I run a freelance consulting and software engineering business since 2011, where I focus on information security consulting and the creation of custom applications that efficiently solve business problems. I have successfully worked with 70+ clients throughout my career and always aim for close cooperation to deliver high-quality results. More about my <a href="#services">services</a> and a selection of <a href="#freelance-works">previous projects</a> can be found below. </p><p> I studied <a href="https://www.uibk.ac.at/studium/angebot/ma-informatik/index.html.en">Computer Science</a> with a focus on information security at the Universities of <a href="https://www.uibk.ac.at/">Innsbruck</a>, <a href="https://informatik.univie.ac.at/en/">Vienna</a>, and <a href="https://www.su.se/department-of-computer-and-systems-sciences/">Stockholm</a>. I was working as project research staff in the <a href="https://informationsecurity.uibk.ac.at/">Security and Privacy Lab</a> of <a href="https://informationsecurity.uibk.ac.at/people/rainer-boehme/">Rainer Böhme</a>, where I studied cross-blockchain data analysis using <a href="https://github.com/citp/BlockSci">BlockSci</a>. I received two awards for my <a href="#academic-works">master thesis</a> and <a href="#academic-works">published</a> my novel address clustering technique at the 29th USENIX Security Symposium 2020. </p><p> I was a <a href="https://summerofcode.withgoogle.com/">Google Summer of Code (GSoC)</a> participant in summer 2020. I worked for the security research organization <a href="https://www.honeynet.org/">The Honeynet Project</a> and added new features to the network analysis tool <a href="https://mitmproxy.org/">mitmproxy</a>. </p><p> If you want to get in touch don&rsquo;t hesitate to send me a <a href="mailto:martin@mplattner.at">mail</a>. </p><p> <strong>Interests.</strong> infosec, software development, data analysis, homelabbing, automation, graphic design </p><ul class="section-list"> </ul></section><section id="services" class="services"> <h2 class=""><a href="#services" class="anchor">#</a> Services</h2> <ul class="section-list"> <li class="item"> <div class="item-title"> <span class="anchor">–</span> Information Security </div> <span class="item-links"> </span> <div class="item-description"> Cyber security has been my passion for many years.
