A defective software update from cybersecurity firm CrowdStrike for its Microsoft Windows hosts left hospitals, banks, airlines, and other businesses scrambling during a global mass IT outage weeks ago.

CrowdStrike founder and CEO George Kurtz has since apologised to their customers and partners in a letter he penned in the aftermath of the outage, saying that nothing is more important to him than their “trust and confidence.”

Almost half (48%) said their organisations focused on activating recovery procedures and guiding the help desk on increased calls, while 44% of respondents said their organisations focused on incident response by activating in-depth security investigations and response procedures.
