The increasing cyber threats and phishing attacks is expected to propel the growth of the cloud-based email security market. Cyber threats and phishing attacks are malicious activities targeting computers, networks, or data, with phishing specifically tricking users into revealing sensitive information. Cyber threats and phishing attacks are increasing as cybercriminals constantly exploit digital communication platforms to deceive users and gain unauthorized access to systems. Cloud-based email security helps address cyber threats and phishing attacks by filtering malicious emails, detecting suspicious links, and blocking malware before it reaches users’ inboxes. It enhances threat visibility, ensures continuous protection, and reduces the risk of data breaches and credential compromise, strengthening overall organizational cybersecurity. For instance, in March 2024, according to Kaspersky Lab, a Russia-based cybersecurity company, phishing attacks grew by 40 percent in 2023, with its anti-phishing systems thwarting over 709,590,011 phishing and scam attempts compared to 2022. Therefore, the increasing cyber threats and phishing attacks are driving the growth of the cloud-based email security industry.
