The past year has shown organizations that uncertainty and a transformed reality are the new normal in business. While remote work was intended as a temporary response to the global pandemic, it is now considered a regular part of the business environment—fundamentally altering the way companies operate.

Ekoparty began as an underground hacking event, but has grown into one of the foremost cybersecurity conferences in Latin America. This year was the 20th anniversary of the incredible infosec event, which takes place every year in Buenos Aires.
