MX-Relay Inbox Defense
Protect mailboxes from phishing, BEC and misleading email
Inbox Defense enhances your existing email security without MX record change and without interruption of mail flow.
The service looks at sender behavior, authentication, payment requests, impersonation, Reply-To deviations and the content of the message. Suspected email is continuously reviewed, automatically monitored and provided with clear notifications.
Why beside a spam filter?
A spam filter is strong in bulk mail, malware and well-known reputational signals. Inbox Defense specifically focuses on the doubts in the mailbox: targeted phishing, CEO fraud, bill fraud, spoofing and unwanted acquisition that at first glance looks reliable. It consequently works alongside Microsoft Defender, Barracuda or your existing mailgateway.
Stronger on top of what you already use
How does Inbox Defense enhance existing email security?
Inbox Defense works on top of your existing email environment and assesses messages in the mailbox, without having to change MX records and without interrupting the mailflow.
The service continues to assess suspicious messages based on context, authentication, sender behavior and content. At increased risk, Inbox Defense automatically follows: move to Junk or MX-Relay Quarantine, inform the user and prepare the message for review.
Quickly active, no mail route conversion
Because Inbox Defense works alongside existing security, you can start without DNS changes and without impact on the normal mail flow. Ideal as an additional protection layer for customers and resellers.
How does it work?
From detection to action in three steps
Inbox Defense makes suspicious e-mail insightful, underpins judgment and helps follow-up immediately. Thus, the administrator remains in control without having to search every message manually.
Beoordelen
The message will be checked for authentication, sender behavior, content, payment requests, Reply-To deviations and known patterns.
Explain
The administrator sees score, level of risk, AI judgment and concrete reasons why the message seems suspicious or safe.
Follow-up and learning
Inbox Defense moves high-risk messages, informs users and uses feedback for trusted senders, block rules and better review.
Phishing and BEC
Recognizes payment requests, urgent language, abnormal senders and attempts to tempt employees to action.
Impersonatie
Signals display-name spoofing, Reply-To mismatches and domains that resemble well-known relationships.
Smart follow-up
Suspect messages get a score, explanation and action: pass, move to Junk or place in quarantine.
AI-analyse
AI helps with context, summary and support, allowing administrators to assess more quickly and consistently.
What happens to a threat?
Inbox Defense assesses the message, explains why something is suspicious and performs the set action. In case of high risk derivatives, the message can be automatically removed from the inbox.
The user may receive a clear warning with details about the sender, receiver, subject and reason for detection.
Actions and insight
- Score and level of risk per message
- Junk or MX-Relay Quarantine in suspicious messages
- Clear security notification to the user
- Review, recovery and training from the management portal
Built for resellers and customers
Resellers manage multiple customers from a clear environment. Per customer, policies, exceptions, trusted senders, block rules, reporting and review can be set up separately.
Learning from feedback
When an administrator trusts, blocks or marks a message as a threat, that choice is taken into account in the next review. Thus, the service is increasingly aligned to the way an organisation uses email.
