What do Microsoft Defender and Purview really cost a small business?

Skip to main content

Last updated: 9 November 2026

The short answer

Prices vary, so we quote rather than guess. Microsoft sells the Defender Suite and Purview Suite as add-ons for Microsoft 365 Business Premium, and bundling both usually costs far less than buying separate tools. Licences and setup are quoted separately, and ABCOM gives a fixed monthly price for your user count.

What each suite includes

Microsoft security and compliance add-on suites for Business Premium
Suite What you get
Defender Suite Entra ID Plan 2, Defender for Identity, Defender for Endpoint Plan 2, Defender for Office 365 Plan 2 and Defender for Cloud Apps
Purview Suite eDiscovery and Audit, Insider Risk Management, and Information Protection and Governance

Typical UK list prices

Per user, excluding VAT, annual commitment, as published in September 2026
Licence Price
Microsoft 365 Business Premium £16.90 per month
Defender Suite for Business Premium £92.40 per year (about £7.70 per month)
Defender and Purview Suites for Business Premium, combined £138 per year

Monthly-commitment licences cost about 20% more. Microsoft changes prices regularly, so these are Microsoft UK list prices that may change. Ask for a current quote.

Why bundling helps

Fewer tools

Industry research cited by Microsoft partners puts the average small and medium business at around 20 security tools, with overlapping licences and alerts nobody has time to investigate.

One invoice

One bundle and one point of contact instead of several separate products.

Managed for you

ABCOM sets the controls up and watches them.

Fixed price

We quote a fixed monthly price for your user count, with fixed-price deployment quoted alongside the licences.

Who should buy what

On Business Basic or Standard, move to Business Premium first, then add Defender. If you handle client, patient or financial data, add Purview for data loss prevention and audit. If you are planning Microsoft 365 Copilot, add both so permissions and sensitive data are under control. Charities and schools can ask about education and charity pricing.

How ABCOM helps

We review what you pay for today, show what a bundle could save and quote it on one invoice. A useful test is whether one successful phishing attack, lost laptop or data leak would cost you more than a year of protection for your whole team. Our managed IT services and vulnerability assessment can show where your gaps are.

Quick answers

Is it cheaper to buy both suites together?

Yes. Bundling both suites usually costs far less than buying the individual licences, and you get one invoice and one point of contact.

Does the price include setup?

No. Licences and setup are quoted separately. ABCOM offers fixed-price deployment so the controls are configured properly.
