Email remains one of the primary communication channels for businesses. However, as the use of Generative AI continues to grow, the threats targeting email are evolving as well.
Phishing attacks no longer necessarily come in the form of emails with poor grammar or obvious typos. With the help of AI, attackers can create messages that are more natural, personalized, and convincing, making them closely resemble legitimate business communications. These techniques can be used to facilitate Business Email Compromise (BEC), credential theft, and various forms of social engineering.
For organizations, this makes email security increasingly difficult to manage through employee awareness alone. When an email is deliberately crafted to appear legitimate, distinguishing genuine messages from attacks becomes significantly more challenging.
As Email Threats Evolve, Email Security Must Evolve Too
Many organizations have traditionally relied on various filtering mechanisms to identify and block suspicious emails. While this approach remains essential, it may not be sufficient to address increasingly sophisticated attacks.
Phishing can be combined with BEC, credential phishing, impersonation, and QR-code phishing or quishing. Threats can also be concealed within attachments or URLs that appear to be part of routine business communications.
Organizations therefore need email security that does more than determine whether an email appears suspicious. It should also be capable of analyzing email content, attachments, and URLs before they reach users.
A layered email security approach can help provide protection from the moment an email enters the organization’s environment, reducing reliance on users’ ability to identify every potential threat themselves.
The Digital Enterprise Dilemma: Advanced Security vs. Infrastructure Control
Digital transformation is driving organizations to adopt stronger business email protection. However, not every organization can or wants to move all internal communications and data to the public cloud.
Data sovereignty, regulatory compliance, existing infrastructure, and the need to maintain control over the IT environment make email architecture an important consideration.
For organizations running Zimbra Collaboration on-premise, TrendAI™ Deep Discovery Email Inspector can be deployed within the email flow as an additional security layer to inspect messages before they are delivered to users.
The solution helps detect various threats, including spear-phishing, Business Email Compromise, malicious attachments, suspicious URLs, and social engineering. Suspicious emails can also be further analyzed through the Virtual Analyzer sandbox to identify potentially malicious behavior.
4 Strategic Benefits of Strengthening Corporate Email Security at the Gateway
Strengthening email security is not simply about adding another security technology. When implemented effectively, this approach can help organizations reduce risk while gaining greater control over incoming emails.
1. Detect More Sophisticated and Hard-to-Spot Threats
TrendAI™ Deep Discovery Email Inspector uses multiple threat detection technologies, including reputation, heuristic analysis, file hash analysis, and Predictive Machine Learning to help identify both known and emerging threats that may not be apparent from the appearance of an email alone.
2. Strengthen Protection Against Phishing and BEC
Deep Discovery Email Inspector helps detect spear-phishing, Business Email Compromise (BEC), and social engineering by analyzing various characteristics of an email, including its header, subject, body, attachment, and delivery information.
3. Analyze Attachments and URLs Before They Reach Users
Deep Discovery Email Inspector analyzes attachments and embedded URLs to help identify malicious content. Suspicious objects can be further analyzed through a sandbox to identify potentially malicious behavior before users interact with them.
4. Provide Flexibility and Control for On-Premise Environments
Deep Discovery Email Inspector can be deployed within the mail flow as an email security gateway, including through MTA mode. This makes it relevant for organizations running Zimbra on-premise that want to add an additional security layer without replacing their existing communication platform.
Zimbra and TrendAI™ Deep Discovery Email Inspector Strengthen Email Gateway Security
To build a more secure email environment, organizations can combine Zimbra Collaboration as the foundation for business communication and collaboration with TrendAI™ Deep Discovery Email Inspectoras a security layer at the email gateway.
Zimbra Collaboration supports a wide range of business communication and collaboration needs within a single environment, including email, calendar, contacts, tasks, and file sharing. The platform also provides flexible deployment options, giving organizations greater control over how their collaboration environment is designed and managed.
Meanwhile, TrendAI™ Deep Discovery Email Inspector strengthens email security through email gateway protection, advanced threat detection, attachment analysis, URL analysis, and sandbox-based inspection.
This approach allows emails to be inspected before reaching users, while suspicious attachments and URLs can be further analyzed through Virtual Analyzer and handled according to established security policies. As a result, organizations can reduce their reliance on users’ ability to identify phishing attempts or malicious emails on their own.
