Research by Tenable reveals at least 40,417,167,937 records were exposed worldwide in 2021.
Calculated by Tenable’s Security Response Team’s analysis of 1,825 breach data incidents publicly disclosed between November 2020 and October 2021, the number of records exposed are a considerable increase on the same period in 2020, which saw 730 publicly disclosed events with just over 22 billion records exposed. This analysis is detailed in Tenable’s 2021 Threat Landscape Retrospective (TLR) report, and includes an overview of the attack path and vulnerabilities threat actors favor, plus insights that will help organizations prepare to face the oncoming challenges in 2022.
