About Me

I am Deividas Lis, a Cyber Threat Intelligence (CTI) guy and Researcher based in Vilnius, Lithuania. My background spans law enforcement and private sector roles, which has given me a well-rounded understanding of the cyber threat landscape. I specialize in tactical and technical CTI, Python scripting, OSINT, and security rule creation, leveraging these skills to develop advanced threat detection solutions and automation workflows.

Currently, I’m working in the finance sector as a CTI specialist, where I focus on identifying, analyzing, and mitigating emerging threats that target financial institutions. Previously, I served as a CTI researcher with NordVPN Threat Protection, which I consider an amazing product for users’ online security. Drawing upon these experiences, I’m able to craft robust intelligence processes and countermeasures to protect organizations against a wide array of cyber threats.

Outside of my full-time role, I offer freelance CTI services and am open to collaborations in threat research, intelligence analysis, and security tool development. If you’d like to discuss potential freelance opportunities or professional partnerships, feel free to reach out to me on LinkedIn.

I’m passionate about driving cybersecurity innovation through automated analysis, research-driven insights, and effective cross-industry collaboration—all in pursuit of a safer digital world.
