Email is one of the most widely used forms of online communication. It is sent and received through a client program, such as **Microsoft Outlook** , **Gmail, or a web-based interface.**Email is a popular communication technique, but it may not always be secure. Interception, reading, and modification are possible during transmission, especially since many email systems do not offer end-to-end encryption. Hackers, government agencies, or even your email provider might read your emails.Secure email gateways such as **Trustifi** AI-Powered Email security providers protect organizations’ email infrastructure from**spam, phishing, and malware**.They filter, block, and quarantine malicious messages to prevent end users from seeing them. These gateways might be hardware, software, or cloud-based, incorporating encryption, data loss prevention, and email archiving. Businesses and governments use them to protect against cyberattacks and comply with security standards.Even with security measures, it’s not 100% guaranteed that your email will never be compromised. It’s always a good idea to be aware of the risks and take steps to protect your information.**Why Do We Need An Email Security Gateway?**———————————————An email security gateway is a tool that helps protect an organization’s email system from unwanted or [malicious emails](https://cybersecuritynews.com/google-revealed-retvec-to-defend-malicious-emails-spam-for-gmail-users/), such as spam, phishing attempts, and malware. It can help to filter out unwanted emails, block malicious attachments, and prevent sensitive information from being sent to unauthorized recipients.This can help protect the organization’s network and data from cyber threats and ensure that only legitimate emails are delivered to the intended recipients. An email security gateway also helps comply with regulatory requirements like HIPAA and PCI-DSS.**What Is A Mail Gateway?**—————————An email gateway serves as a bridge between different email systems. It efficiently manages the transfer of emails between different networks and mail servers. The mail gateway links a local network to the Internet.* **Incoming email:** When an email is sent to a recipient on the local network, the message is first sent to the mail gateway. You can protect your business email from malicious email using Inbound Shield.* **Outgoing email:** When a user on the local network sends an email, the message is first sent to the mail gateway. You can protect your business email from malicious email with the hekp of Outbound Shield that assist emails that are automatically sent securely and compliant with easily-enabled Data Classification and Data Loss Prevention rules.**What Is Email Security And How It Works?**——————————————–Email security safeguards email messages from [unauthorized access](https://cybersecuritynews.com/chatgpt-next-web-ssrf-vulnerability-unauthorized-access/), disclosure, change, and destruction. We can use encryption, authentication, and anti-spam and anti-virus filters.TLS is a widely used encryption method for securing internet email. S/MIME enables email encryption and signature. Email senders can be verified using DMARC, Sender Policy Framework, and Domain-based message authentication.Anti-spam and anti-virus filters block malware and phishing emails. Email security involves continual updating and monitoring to stay ahead of emerging threats.**Here Are Our Picks For The Best Email Security Gateways**———————————————————–* **[Trustifi Email](https://trustifi.com/)**– Comprehensive email security with advanced encryption and real-time threat protection.* **[Barracuda Email Security](https://www.barracuda.com/products/email-protection/email-security-gateway)** — Protects against email-borne threats with advanced filtering and encryption.* **[Proofpoint Email Protection](https://www.proofpoint.com/us/products/email-security-and-protection/email-protection)** — Provides robust defense against phishing, malware, and spam with detailed reporting.* **[Microsoft Defender for Office 365](https://www.microsoft.com/en-in/security/business/siem-and-xdr/microsoft-defender-office-365)** — Integrated security solution offering advanced threat protection for Office 365.* **[Cisco Secure Email](https://www.cisco.com/site/us/en/products/security/secure-email/index.html)** — Comprehensive email security with threat intelligence and data loss prevention.* **[Forcepoint Email Security Solution](https://www.forcepoint.com/product/email-security)** — Defends against email attacks with real-time threat intelligence and data protection.* **[Sophos Email](https://www.sophos.com/en-us/products/sophos-email)** — Offers advanced email threat protection with AI-based phishing detection.* **[SpamTitan](https://www.spamtitan.com/)**– Advanced email filtering with robust spam and malware protection.* **[Comodo Dome Antispam](https://www.comodo.com/business-security/email-security/antispam-gateway.php)** — Delivers effective spam and phishing email filtering with advanced security features.* **[Trustwave MailMarshal](https://www.trustwave.com/en-us/services/email-security/)** — Powerful email security gateway with comprehensive threat protection and policy enforcement.**10 Best Email Security Gateways** **Features** Stand Alone Feature Pricing Free Trial / Demo **1.
