Hacking is the main cyber-attack for which companies have required on-site assistance. It accounts for 23.5% of all attacks.

Phishing (21%) and ransomware attacks (17% ) also top the list. Phishing consists in inciting the victim to perform an action in order to recover personal or confidential data. Ransomware, on the other hand, refers to attacks aimed at blocking the victim's device and demanding a sum of money in exchange for unlocking it. This type of attack is more likely to affect businesses, given their greater solvency.
