Email Security
Protecting your business from email-based threats with advanced detection and continuous monitoring.
Expert email security that keeps malicious emails out of your inbox
Email remains the primary way businesses communicate, but it’s also the most exploited attack vector for cyber criminals. Phishing emails, malicious attachments, ransomware and spoofed sender addresses account for over 90% of successful cyber attacks on UK businesses.
The challenge is that these attack methods are only growing more sophisticated and dangerous. Our email security packages are designed to combat this, using spam filtering, machine learning and continuous monitoring to intelligently protect your team’s inboxes from targeted attacks as well as new or unknown threats.

Why businesses choose Acronyms for email security
-
Remove the worry of email security threats from your agenda
You’re not buying software and managing it yourself. Our engineers monitor threats, configure policies and respond to suspicious activity on your behalf. When a user reports a suspicious email or a new phishing campaign emerges, you have a team who knows your business handling the response.
-
Instant threat removal across your organisation
When a malicious email bypasses initial detection, our Premium package allows our engineers to remove it from all mailboxes instantly through a centrally managed dashboard. You also benefit from a spam-fighting community where threats identified by any customer get blocked for everyone using Mesh.
-
Built for Microsoft 365 integration
Our email security integrates natively with Microsoft 365 through API connections, requiring no hardware installation or complex configuration. Standard and Premium packages sync automatically with your Microsoft user licensing, which means shared mailboxes receive protection without additional charges.
-
Set policies that match your operations
Email security policies can be set at organisation, domain and user levels rather than applying the same rules to everyone. If specific departments need stricter filtering, individual users need certain senders whitelisted or different locations require different controls, your email security adapts accordingly.
Frequently Asked Questions
-
Yes. Microsoft 365 includes basic Exchange Online Protection, but it only catches known threats using signature-based detection. It misses sophisticated phishing attempts, business email compromise and zero-day attacks because these don’t match existing threat patterns.
-
Anti-spam blocks unwanted bulk marketing emails and known malware by checking messages against threat databases and predefined rules. If a threat matches something already identified, it gets blocked.
Email security uses machine learning to detect sophisticated, targeted attacks that anti-spam misses. It analyses sender behaviour, message patterns and content characteristics to identify malicious activities that don’t match existing threat signatures.
-
Blocked emails go into a quarantine area where they’re typically held for 30 days before automatic deletion. Users receive regular quarantine digest emails showing what’s been blocked, allowing them to release legitimate messages if needed. Administrators can review quarantined emails through a management dashboard and adjust filtering rules if legitimate senders are being caught incorrectly.
-
Deployment takes between 15 and 30 minutes. We make DNS changes to route your email through the security gateway and configure policies in your Microsoft 365 environment. No software needs installing on devices or servers, and no interruption to email service. Standard and Premium packages sync automatically with your Microsoft 365 user list through API connections.
