  • Complex and fragmented regulations: cybersecurity regulations vary from one jurisdiction to another, resulting in a fragmented approach when addressing threats. It can be difficult for companies to comply with regulations and consistently implement security measures.
  • Organizations often depend on suppliers, service providers, and third party vendors for different aspects of their operations. Cyberattacks that target these partners could have an impact on the security posture of your organization.
  • A shortage of cyber-expertise is a growing concern: organizations might struggle to retain and recruit skilled cybersecurity staff, making them vulnerable to attack. The rapidly changing nature of cyber threats requires that existing staff be trained and continually upskilled.
  • It is difficult to track cybercriminals: cybercriminals are often anonymous or operate across borders. Low likelihood of detection or prosecution may encourage malicious actors to carry out their actions with little risk.

Cloud Email Security Challenges & Threats

To protect sensitive data, organizations must address several threats and challenges that cloud email security presents. An unmanaged attack surface is one of the biggest risks as it can create vulnerabilities within the cloud infrastructure that malicious actors may exploit. Human error and misconfigurations are also contributors to cloud security threats, because they may unintentionally expose sensitive information or weaken overall security.

Increasing threat incidents in the cloud and the compromised cloud accounts also are reasons for concern. The number of cloud files that contain sensitive information has increased, so it is important to take security measures to avoid unauthorized access to data and data breach. Cloud-based email services like Microsoft 365 are vulnerable to attack, so it is important to enhance security against new attack vectors.

Addressing these threats and challenges requires organizations implementing best practices for cloud email security. Sender authentication can reduce the risk of a phishing attack by verifying the email’s authenticity. Spam filters detect and block malicious content before reaching the users’ mailbox. Multi-factor authentication requires multiple credentials to access the account, providing an extra layer of protection.

Additionally, it is important to separate business email from personal email to help minimize any potential risk and negative impact of a successful compromise. Avoid using public Wi-Fi to reduce the risk of interception or unauthorized access to sensitive emails. Backing up important files regularly can also help mitigate the risk of data loss in a ransomware attack or a security breach.

The Evolving Landscape of Cloud Email Security

Cloud email adoption has seen a dramatic increase in recent years due to a variety of benefits. These include ease of use and reduced costs for installation and maintenance, as well as the increasing adoption of multiple cloud services. This increased adoption has also led to an increased awareness about email security threats.

Phishing attacks are a major security concern associated with cloud-based email. Phishing attacks are a persistent threat that has seen a rise in recent years due to the increased use of cloud email by businesses and the widespread implementation of unsecured cloud environments.

Business Email Compromise (BEC) is also a major concern. These dangerous impersonation schemes target C-suite executives, but they also affect employees from HR, IT and finance. Successful BEC attacks can lead to financial loss and data compromise.

Emerging trends in cloud email security encompass several important aspects, including AI-powered threat detection and prevention, email encryption and data loss prevention technologies, and integration with threat intelligence and security analytics.


AI-Powered Threat Detection and Prevention

AI-powered detection and prevention of security threats is an important tool for mitigating these risks. Criminals can use the same AI features to create new, more efficient attacks. They are able to manipulate AI's abilities in analyzing data, detecting anomalies and providing predictive information. AI can be used to detect threats, identify weaknesses in systems, analyze events live, and improve overall security.

Email Encryption and Data Loss Prevention Technologies

The encryption of emails is a critical step in protecting sensitive data transmitted via cloud-based email platforms. Encrypting email content protects it from unauthorized access. Only authorized recipients are able to decrypt the messages and view them, which adds an additional layer of security.

The use of data loss prevention technologies is also essential to prevent accidental or deliberate leakage of sensitive information. They can check outgoing email for sensitive information and enforce policies that prevent unauthorized disclosure. DLP helps organizations comply with regulations on data protection and protect valuable information.

Integration with Threat Intelligence and Security Analytics

Integration of cloud email security and threat intelligence with security analytics improves overall protection against threats relating to email. With threat intelligence, organizations can keep up with the most recent threat landscape including new attack techniques and indicators.
