Advanced Email Threat Protection for UK SMEs

Email is still the way most attackers get in. If you only have the spam filter that ships with your mailbox, you are catching yesterday's threats and missing the targeted ones aimed squarely at your finance and leadership inboxes. This page explains what advanced protection adds, how AMVIA deploys it, and what it costs — and links back to our managed cybersecurity pillar and the wider business email security hub.

What is advanced email threat protection?

Advanced email threat protection extends basic filtering with four capabilities standard tools lack: attachment sandboxing (detonating files in isolation before delivery), click-time URL rewriting, impersonation and display-name detection, and machine-learning phishing analysis. Where basic filtering relies on known signatures and reputation lists, advanced protection inspects behaviour — so it catches attacks no one has seen before.

The practical difference is what reaches your users:

• Basic filtering blocks known spam and previously-reported malware by signature and sender reputation.
• Advanced protection opens attachments in a sandbox, checks every link at the moment it is clicked, flags emails that impersonate your CEO or suppliers, and scores message intent with ML.
• Managed advanced protection adds a human team that tunes the policies, reviews what was blocked, and responds when something gets through.

What is included in AMVIA's service?

AMVIA delivers advanced email threat protection as a fully managed service: we design the threat policies, deploy them with zero downtime, monitor what is blocked, and report monthly. You get a single accountable provider for email security rather than a console you have to learn and babysit.

• Proactive protection: continuous monitoring and threat detection on Microsoft Defender for Office 365 and the Barracuda email security suite.
• Expert management: UK-based, Microsoft-certified engineers handle configuration, tuning and incident response.
• Monthly reporting: clear reports on threats blocked, incidents handled and recommended improvements.
• Dedicated support: direct access to your account team for changes and escalations, with critical issues responded to within one hour.

How does AMVIA deploy email threat protection?

Deployment is a four-step process designed to add protection without losing a single email. We audit your current mail flow first, configure policies to your industry's threat profile, then cut over and tune continuously. For a standard Microsoft 365 tenant the policy work is measured in hours, not weeks.

1. Email audit: we map your mail flow, find gaps, and review existing filtering rules. 2. Policy configuration: custom policies for phishing, spoofing, malware and impersonation, tuned to your sector. 3. Cutover: for gateway deployments we update MX records and route mail through advanced filters with zero downtime; for Microsoft 365 we enable Defender for Office 365 policies in-place. 4. Monitoring and tuning: ongoing review of blocked threats, false-positive checks and quarterly policy adjustments.

Why do UK SMEs need advanced email threat protection?

UK SMEs need it because phishing is now the dominant attack route and basic filters do not stop targeted campaigns. Government data shows email-borne attacks are the most common breach UK businesses face, and the cost of a serious incident runs into thousands of pounds plus days of disruption.

According to the UK Government's Cyber Security Breaches Survey 2025, 43% of UK businesses experienced a cyber breach in the last year, and around 85% of those breaches involved phishing. The same survey puts the average cost of the single most disruptive breach at £3,550 for UK businesses, and estimates roughly 19,000 UK businesses were hit by ransomware in the past year — much of it delivered by email. The NCSC's phishing guidance confirms layered technical defence plus user awareness as the recommended approach.

This is exactly why advanced protection pairs with phishing protection and defends against business email compromise, the highest-value email fraud SMEs face.

Advanced protection vs basic email filtering

Standard email filtering is a sensible baseline. Advanced protection is what stops the attacks built specifically to slip past that baseline.

How much does advanced email threat protection cost?

For most UK SMEs the most cost-effective route is Microsoft 365 Business Premium, which includes Microsoft Defender for Office 365 Plan 1 at no extra licence cost. Beyond that, you are paying for management — the policy tuning and monitoring that turns a licence into real protection.

• Microsoft Defender for Office 365 Plan 1 is included in Microsoft 365 Business Premium, priced at £16.90 per user/month (ex VAT, annual). It is not included in Business Basic or Business Standard.
• Businesses on lower-tier licences can add Defender for Office 365 Plan 1 standalone, or run a third-party gateway such as Barracuda.
• AMVIA's managed Microsoft Defender for Business wraps the licence in configuration, monitoring and reporting.
