2021 Annual Threat Report

Review the events and trends that impacted the cybersecurity landscape in 2021 in our Annual Threat Report. From fallout of the SolarWinds attack to the impact of the Log4j vulnerability.

The goal of this report is to provide insights and context of individual events and larger trends so organizations can take concrete actions to better defend their infrastructure.

“I don’t think people appreciate the advantage our clients have. I have identified maliciousness in one network environment and based on my finding and categorization of the activity, those IOCs are identified and elevated across all our IronDome clients. Every environment is different. It is extremely valuable to collaborate with other hunters and compare how an attack, like SolarMarker, looks across multiple environments.” 

- Tamara Fisher, IronNet Threat Hunter
