Email Security Market Growth Factors

Rising Malware, Phishing Activity, and Cyber-Attacks Drive the Demand for Scalable Email Security Solutions

Cyber-attackers have increased the scope of their attacks. They are developing innovative techniques for stealing identities, such as creating external domain names with fake URLs and email header domains. Also, they engage in attacks that combine email and cloud-based accounts or use outbound mail as a bot which threatens an organization’s reputation.

• According to Acronis findings in 2023, the number of email-based phishing attacks increased by 464% in 2023 as compared to 2022.

Additionally, cyber-attackers have leveraged pandemic-driven fears and uncertainties to launch email phishing activities. For instance,

• A study by SlashNext in 2022 examined billions of attachments, messages, and URLs in mobile phones, email, and browsers for over a half year, resulting in around 255 million attacks. They reported a 61% rise in the rate of phishing attacks compared to the last year.

Such an increase in the volume of attacks continues to evolve, becoming more sophisticated and costly for users to aid the adoption of electronic mail security solutions.

RESTRAINING FACTORS

Lack of Awareness to Implement Email Security Solutions and Weak IT Infrastructure May Hinder the Market Growth

Many organizations are not able to set up a fundamental electronic mail security infrastructure for basic operations. They are still not conducting formal training on the dangers of cyber threats, email phishing, and available protections; this network infrastructure is exposed at high risk. For instance,

• According to Stanford University researchers, an employee error accounts for approximately 88% of all data breaches.

Moreover, a lack of organizational foresight and weak IT infrastructure impacts the business, processes, and users. The IT and security teams are forced to review their electronic mail security controls due to significant growth in the volume and effectiveness of these attacks, as well as cloud migration. This is hindering the growth of electronic mail security solutions in the market.
