Security before the inbox
Fewer threats.
Cleaner communication.
Email remains one of the most common routes into a business. Effective filtering helps remove unwanted and dangerous messages before users have to decide whether a link, attachment or sender can be trusted.
Cut inbox noise
Spam and bulk-message controls reduce unnecessary email so users can focus on legitimate business communication.
Layered protection
Anti-spam, antivirus and threat filtering work together to provide more than a single line of defence.
Protect productivity
Reducing dangerous and unwanted messages helps limit disruption, clean-up time and avoidable security incidents.
Filter before users have to decide
Good email security reduces the number of suspicious messages your team ever needs to see.
What email protection can include
Filter. Scan.
Protect. Control.
The right protection depends on your mail platform, user base and risk profile. Novicus can help align filtering and protection with the way your business email is actually used.
Spam filtering
Reduce unsolicited and low-value email before it fills user inboxes or distracts staff from legitimate communication.
Phishing protection
Identify and filter suspicious messages designed to steal credentials, impersonate trusted senders or direct users to harmful sites.
Antivirus & malware scanning
Scan inbound email and attachments for known malicious content and common email-delivered malware threats.
Ransomware threat reduction
Apply filtering and attachment controls that help reduce the chance of ransomware payloads reaching end users through email.
Sender & impersonation checks
Help identify suspicious sender patterns and messages that attempt to imitate executives, suppliers or trusted business contacts.
Suspicious link protection
Reduce exposure to malicious URLs and deceptive links that direct users to credential-harvesting or compromised websites.
Mail flow & security policies
Apply practical controls around accepted senders, blocked content, quarantine behaviour and supported business mail-flow requirements.
Monitoring & support
Review filtering behaviour, troubleshoot delivery concerns and adjust supported policies as business requirements change.
How protection is introduced
Assess. Configure.
Protect. Refine.
Email protection works best when it is configured around your actual domain, mail platform and users rather than applied as a generic setting.
Review the mail environment.
We look at your domain, current mail platform, known spam or delivery issues and the level of protection already in place.
Apply the right controls.
Filtering, scanning and supported mail-flow settings are configured around the agreed protection approach.
Filter incoming threats.
Suspicious mail is checked and handled according to the security and quarantine policies selected for the environment.
Adjust as needs change.
Rules and filtering can be reviewed over time to improve protection while reducing unnecessary false positives.
Security without blocking business
The goal is simple: stop more unwanted mail while keeping legitimate messages moving reliably.

Frequently asked questions
Email security & filtering,
made clearer.
Answers to common questions about spam filtering, phishing protection and business email security.
Email filtering can help reduce spam, phishing messages, malicious attachments, malware, ransomware delivery attempts and other suspicious email before it reaches users.
No security layer can guarantee that every malicious message will be stopped. Filtering reduces exposure and should form part of a broader security approach that also includes protected endpoints, strong account security and informed users.
Filtering systems are designed to distinguish legitimate mail from unwanted or dangerous messages, but false positives can occur. Quarantine and policy tuning help manage legitimate messages that are incorrectly flagged.
Novicus supports Microsoft 365 and Exchange Online as part of its broader cloud services. The final filtering and protection approach depends on the existing Microsoft 365 environment and the security requirements agreed for the business.
Yes. An existing email environment can be reviewed to determine what filtering, protection and policy improvements are practical without unnecessarily disrupting normal mail flow.
No. Email filtering protects one important attack route, while endpoint antivirus and broader security controls protect devices and systems. They work best as complementary layers.
