Email Filtering and Protection
Block the Threats Before Your Team Ever Sees Them
Phishing attacks, malicious attachments and spam are a constant presence in every business inbox. Our managed email filtering service sits in front of your email environment, analysing every inbound message and blocking harmful content before it reaches your team.
One Click Is All It Takes
The majority of cyberattacks begin with an email. Attackers invest significant effort into crafting messages that look legitimate, mimicking real suppliers, colleagues or service providers with alarming accuracy.
For businesses without robust email filtering in place, every email that arrives is an unscreened risk. Staff are expected to make security judgements on dozens or hundreds of messages every day, which is neither realistic nor fair.
Managed email filtering removes the vast majority of threats before your team ever encounters them. Phishing attempts, malware laden attachments, spoofed sender addresses and bulk spam are all identified and blocked automatically.
Advanced Phishing Detection
Modern phishing attempts go far beyond obvious spam. Our filtering analyses message content, sender behaviour and link destinations to identify sophisticated phishing attacks that basic filters would miss entirely.
Attachment and Link Scanning
Malicious files and dangerous links are two of the most common ways attackers deliver malware. Every attachment and URL in inbound emails is checked before delivery.
Managed and Fine-Tuned for Your Business
We configure and manage your filtering settings to suit the way your business operates, adjusting the configuration as your email environment evolves.
Protection That Learns as Threats Evolve
Email threats are not static. At AOIT, we do not just set up email filtering and walk away. We monitor how your filtering is performing, stay current with the latest threat intelligence and adjust your configuration accordingly.
Our partners benefit from a properly managed filtering setup that balances strong protection with clean deliverability.

Frequently Asked Questions
Email filtering sits between the internet and your inbox, analysing every inbound message before it is delivered. Messages showing signs of phishing, malicious attachments or spam are blocked or quarantined.
No filtering solution catches one hundred percent of threats. However, a well-configured managed filtering service blocks the vast majority of malicious emails and significantly reduces the risk of a successful attack.
Blocked emails are typically quarantined rather than permanently deleted. You or your team can review quarantined messages and release any that have been incorrectly flagged.
In practice, the impact on delivery speed is negligible. Modern filtering solutions are designed to process messages quickly.
Most email filtering solutions focus primarily on inbound external email, which is where the vast majority of threats originate. For internal email, other security controls play a more significant role.
Yes. Our email filtering solutions are compatible with the major business email platforms. We will confirm compatibility during the initial assessment.
Business email compromise attacks are different from typical phishing. They often contain no malicious link or attachment, just a convincing message asking for a payment or a change of bank details, so a standard filter has little to catch. Our filtering adds impersonation checks that flag look-alike domains and unusual sending patterns, but the most effective protection is a verification step outside of email, such as a phone call on a number you already have, before acting on any request to change payment details.
