Phishing Protection for UK Businesses

Why is phishing the threat UK SMEs must fix first?

Phishing is the most common way attackers get into UK businesses, so it is the single control with the highest return on effort. According to the 2025 UK Cyber Security Breaches Survey, 85% of businesses that identified a breach pointed to phishing as the most common attack type. Fix email, and you close the door most criminals walk through.

The threat is also getting cheaper to run and harder to spot. Roughly 35% of UK SMEs now cite AI-generated attacks as their top concern, and an estimated 99% of phishing volume is bulk, automated email. The UK's National Cyber Security Centre treats phishing as a primary threat for organisations of every size (NCSC phishing guidance).

• Email is the cheapest, most scalable route into a business.
• One click can hand over credentials, money, or both.
• Most breaches start here, so most prevention budget should too — see the DCMS Cyber Security Breaches Survey 2025.

What's included in AMVIA phishing protection?

AMVIA phishing protection is built in three layers, because no single control stops every attack. Technical filtering blocks the bulk volume, training hardens the people that targeted attacks aim for, and simulation measures whether the first two are actually working. You get all three from one provider.

Layer 1 — Technical email security. Microsoft Defender for Office 365 and Barracuda email protection assess every inbound message for spoofed domains, malicious links, suspicious attachments and impersonation, using machine-learning models that update as new tactics appear.

Layer 2 — Security awareness training. Staff learn to recognise phishing and the exact steps to take when a message looks wrong. Technical controls alone cannot stop sophisticated spear phishing or business email compromise — people are the last line.

Layer 3 — Phishing simulation. Controlled, realistic phishing simulation training tests real-world susceptibility and gives you a measurable click rate to drive down over time.

How does AMVIA protect you from phishing?

We start by finding the gaps, then close them and keep them closed. The process is a continuous loop, not a one-off install, because attacker tactics and your staff both change month to month.

1. Threat assessment — we review current email security, domain configuration (SPF, DKIM, DMARC) and recent phishing attempts. 2. Technical controls — anti-phishing filters, impersonation protection, and safe links and attachments policies. 3. Staff awareness — training paired with simulated attacks so learning is tested, not assumed. 4. Ongoing defence — continuous monitoring by our in-house 24/7 SOC, regular simulations and policy updates.

Critical issues are responded to within one hour by a UK-based team, and our managed detection and response service catches the threats that get past the inbox.

Technical controls alone vs layered phishing protection

Buying a spam filter is not the same as having phishing protection. Filters stop the bulk noise but miss the targeted attacks that cause real financial loss. The table shows why layering matters — and where each layer earns its place.

Regular simulations move staff click rates from a typical untrained 20–30% (industry benchmark) to below 5%; AMVIA clients typically achieve sub-5% click rates within six months.

How much does phishing protection cost?

Phishing protection is usually included within a managed cybersecurity package rather than priced as a single line item, because the layers reinforce each other. Standalone email security and simulation programmes are available where you only need one piece. Microsoft 365 Business Premium, which includes Defender for Office 365, lists at £16.90 per user per month (Microsoft 365 pricing).
