ESET vs Nagios

ESET is an IT security company headquartered in Bratislava, Slovakia that was founded in 1992 by the merger of two private companies. ESET offers anti-virus and firewall products such as ESET NOD32 and competes in the antivirus industry. The company was founded in 1992 when Miroslav Trnka and Peter Pako, authors of antivirus software NOD, partnered up with Rudolf Hrub. They adopted the name of the Egyptian goddess of health, marriage and love as the company name. In 1998 NOD received the VB100 award of Virus Bulletin, which helped the company establish subsidiaries in the USA, Argentina and Singapore, and development facilities in Poland and Czech Republic.

Nagios, an open-source computer-software application, monitors systems, networks and infrastructure. Nagios offers monitoring and alerting services for servers, switches, applications and services. It alerts users when things go wrong and alerts them a second time when the problem has been resolved. Ethan Galstad and a group of developers originally wrote Nagios as NetSaint. As of 2015 "Agios" also transliterates the Greek word, which means "saint".
