One of the most popular methods used by cybercriminals to infiltrate corporate networks and take sensitive data is through email. Email security is a critical issue for every company, as over 90% of attacks on organizations begin with a malicious email.
In this article, we will discuss the best practices for ensuring robust email security in enterprises.

Importance of Email Security in Enterprises
In addition to safeguarding businesses from outside threats, email security is crucial for guarding a brand’s clients from external risks. Without adequate email security measures, businesses expose their clients, customers, and themselves to the repercussions of cybersecurity disasters.
Attackers are always coming up with new strategies to get past organizations’ firewalls by taking advantage of email and users’ neglect for enterprise email security best practices.
Organizations must defend against a growing variety of attacks, ranging from common email risks like malware and spam to sophisticated targeted attacks like phishing, spear-phishing, and wire transfer phishing.
Common Email Security Threats
- Phishing Attacks: Phishing emails use social engineering, spoofing, and other tactics to trick users into clicking on malicious links or attachments, which can lead to data breaches and other cybersecurity incidents.
- Malware and Ransomware: Malware and ransomware are malicious software programs that can infect an organization’s network and cause significant damage.
- Business Email Compromise (BEC): BEC attacks are a type of phishing attack that targets businesses and involves impersonating a trusted individual or organization to trick employees into transferring money or sensitive information.
- Email Spoofing: Email spoofing is the practice of sending emails with a forged sender address, which can be used to trick users into thinking the email is from a trusted source.
Impact of Email Security Breaches on Enterprises
Businesses that experience email security breaches may suffer from loss of revenue, damage to their reputation, and legal liability.
In addition, email security can lead to the loss of sensitive data, including intellectual property, trade secrets, and personally identifiable information.
Best Practices for Enterprise Email Security
1. Implement Strong Password Policies
- Encourage employees to use complex and unique passwords to prevent unauthorized access to email accounts.
- Regularly updating passwords can help prevent unauthorized access to email accounts.
- Implementing 2FA can add an extra layer of security to email accounts and prevent unauthorized access.
2. Train Employees on Email Security Awareness
- Regular security training sessions can help employees identify and respond to email security threats.

7. Create Strong Email Backup and Recovery Strategies
- Regular backups of email data can help ensure that email data is not lost in the event of a cybersecurity incident.
- Testing the restoration process can help ensure that email data can be recovered in the event of a cybersecurity incident.
- Cloud-based backup solutions can provide an additional layer of security for email data.
8. Conduct Regular Security Audits and Assessments
- Periodic email security audits can help identify vulnerabilities and weaknesses in email security strategies.
- Vulnerability assessments and penetration testing can help identify vulnerabilities and weaknesses in email security strategies.
- Addressing identified weaknesses promptly can help prevent email security breaches.
9. Develop a Comprehensive Incident Response Plan
- Establishing an incident response team can help ensure that email security breaches are detected and responded to in a timely manner.
- Documenting incident response procedures can help ensure that email security breaches are responded to consistently and effectively.
- Conducting post-incident analysis can help identify areas for improvement in email security strategies.
10. Monitor and Analyze Email Traffic
- Email security monitoring tools can help detect and respond to email security breaches in a timely manner.
