Mariana Segulin 

Mariana Segulin is an Argentine journalist with a strong background in computer science, known for her work on Todo Noticias (TN) and El Trece. Her focus on cybersecurity, technology, and clear communication has made her a respected voice in national media, blending technical expertise with journalistic insight.

From Technical Support to Newsroom: The Beginning

Mariana Segulin’s professional path started not in front of a camera, but behind a computer screen. Trained as a computer technician, she spent her early years working in tech support and hardware repairs. This solid technical foundation became one of her key differentiators when she later transitioned into journalism. Early stints at local outlets like Red 92 and La Plata Tevé gave her firsthand experience in media production and press coordination. It was clear from the outset that her dual command of technology and communication would shape her career uniquely.

Rising in National Media

Segulin joined the national news network Todo Noticias (TN) in 2017, where she quickly became a familiar face. Programs like “Buena Semana” and the morning show “Tempraneros” gave her a platform to connect with a wide audience. Her segments often focused on current affairs, tech innovation, and digital life — themes she navigated with clarity and authority. Viewers were drawn to her straightforward style and her ability to make complex topics accessible. Over time, she carved out a distinct space within the newsroom as a communicator deeply grounded in technology.

A Voice in Cybersecurity

One of the areas where Segulin has made a significant impact is cybersecurity. Far from being a buzzword, it became a personal and professional mission. She participated in numerous talks and educational campaigns aimed at increasing public awareness about online risks and digital hygiene. Rather than relying on jargon or fear tactics, she built her message on useful, easy-to-understand practices, making her a valuable bridge between the tech world and everyday users.

A Career Shift with Purpose

In May 2025, after eight years with TN, Mariana Segulin announced her departure from the network. The decision marked the beginning of a new chapter. She shared the news through her social media platforms, thanking her colleagues and followers for the journey and hinting at upcoming projects. Her next steps, although still under wraps, are expected to continue blending media, education, and technology. The move wasn’t a retreat but a recalibration — a choice to pursue work aligned even more closely with her evolving passions.

Engaging with the Public, On and Offline

Segulin has cultivated a loyal and active online following. Her Instagram account, followed by over 100,000 users, offers a mix of professional updates, reflections on current events, and glimpses into her personal world. She treats the platform as more than just a broadcasting tool; it’s a space for genuine interaction and conversation. This approach has allowed her to build trust and remain relevant in a media landscape that increasingly values authenticity.

Journalism with a Technical Pulse

Mariana Segulin stands out not just for what she covers but how she covers it. She doesn’t shy away from technical subjects — she thrives on them. Whether breaking down a new cybersecurity threat or explaining how algorithms affect our lives, she brings depth, rigor, and a journalist’s instinct for clarity. That balance of tech fluency and human insight makes her work not just informative, but resonant.
