Zero-day vulnerabilities and fileless attacks are now deemed the most dangerous threats to the enterprise. According to a study conducted by the Ponemon Institute and sponsored by Barkly, called the "2018 State of Endpoint Security Risk report," nearly two-thirds of enterprise players have been compromised in the past 12 months by attacks which originated at endpoints, which the organization says is a 20 percent increase year-on-year. Such attacks can prove costly, with the average company enduring a cost of $7.12 million, or $440 per endpoint. Small to medium-sized businesses, which may not have the same cybersecurity solutions or teams in place due to investment limitations, suffer more -- with the same damage cost of endpoints close to double at $763. In total, the average cost of a successful endpoint-based attack has increased by roughly 42 percent year-on-year.
