How Much Does Managed Cybersecurity Cost in the UK?

That headline range is the answer most buyers want, but the figure that matters is what sits inside it. The same per-user price can buy a thin antivirus subscription or a fully managed cybersecurity service with a human analyst watching your estate around the clock. Below is exactly what moves the number, tier by tier, so you can budget honestly and compare like with like.

What drives the cost of managed cybersecurity?

Price is set by six variables, not one. The biggest is service scope: detection-only tooling is cheap, but a service that investigates and contains threats on your behalf costs more because there are people behind it. Get clear on these before you compare quotes.

• Number of users and endpoints — most services are priced per user or per endpoint per month. More devices means a higher total, but the per-unit rate usually falls with volume.
• Service scope — basic endpoint protection is far cheaper than a package adding managed detection and response, SOC monitoring, email security, and vulnerability management.
• Compliance requirements — financial services, healthcare and legal firms often need extra controls, audit support and reporting that lift the price.
• Monitoring hours — business-hours cover is cheaper than 24/7. For anyone handling sensitive data, round-the-clock 24/7 security monitoring is the sensible floor.
• Number of sites — multi-site businesses may need additional network security and site-specific monitoring.
• Response level — some services only detect and alert. Full MDR investigates and actively contains the threat for you.

The UK threat picture justifies the spend. According to the UK government's Cyber Security Breaches Survey 2025, 85% of businesses that experienced a breach identified phishing as the attack vector (DSIT 2025) — which is why email protection is non-negotiable at every tier.

What do the managed cybersecurity pricing tiers actually buy?

Most UK providers cluster around three tiers. The table below shows indicative monthly per-user pricing for SMEs with 20–200 users. Use it to sanity-check any quote: if a "comprehensive" price looks like a basic one, the scope has been cut somewhere — usually the 24/7 monitoring or the incident response.

*Prices are indicative for UK SMEs with 20–200 users (typical UK 2026 range). Actual pricing depends on your specific requirements.*

The jump from Standard to Comprehensive is where 24/7 SOC monitoring, active incident response and threat hunting come in. For a regulated firm, that jump is not optional — it is the difference between being told you were breached and having someone stop it at 3am.

What does a managed cybersecurity service include for the money?

A service worth paying for covers detection, prevention and response across every entry point — endpoint, email and identity. AMVIA's stack is built on Microsoft Defender for Endpoint and the Barracuda email and network suite, monitored by our in-house 24/7 SOC. One provider, one bill, no tool sprawl.

At AMVIA the standard inclusions are:

• Endpoint detection and response via Microsoft Defender for Endpoint, monitored continuously by our SOC.
• Email security and anti-phishing through the Barracuda suite — your highest-risk channel given the phishing data above.
• 24/7 monitoring and managed detection — alerts triaged and acted on by analysts, not left in a dashboard.
• Vulnerability scanning and patch oversight through ongoing vulnerability management.
• Incident response with investigation and containment, ideally inside the monthly fee rather than billed per incident.

For Microsoft-centric businesses, much of this builds on licensing you may already own. Microsoft 365 Business Premium lists at £16.90 per user per month (ex VAT, annual commitment) per Microsoft UK, and includes Defender for Business and Intune — so a good provider extends what you have rather than selling you a parallel stack.

Is managed cybersecurity worth the cost for a UK SME?

Yes — the maths is straightforward when you weigh the subscription against the cost of a breach. The government's Cyber Security Breaches Survey 2025 puts the average cost of the most disruptive breach at £3,550 (DSIT 2025), and that excludes downtime, lost trust and regulatory exposure. A year of managed protection typically costs less than a single serious incident.

The NCSC is clear that small and medium businesses are routinely targeted precisely because their defences are assumed to be weaker. Managed cybersecurity closes that gap without you hiring a security team — you rent the capability per user instead. For most SMEs, the incremental cost of covering one more user is trivial against the downside of leaving them exposed.

AMVIA protects 1,200+ UK businesses and holds Cyber Essentials Plus and Microsoft Solutions Partner status (Modern Work, Security, and Infrastructure). Our customers rate us 4.8/5. That is the practical case: a single accountable provider, security-first, staffed by Microsoft-certified engineers.

How does AMVIA price managed cybersecurity?

AMVIA prices per user per month, with the scope agreed up front so there are no per-incident surprises. We map your current Microsoft licensing first, then layer only what is missing — usually managed detection, email security and 24/7 SOC cover — so you are not paying twice for overlapping tools.

We will not quote a number until we have seen your estate. A short free security audit tells us your user count, your current controls and your compliance obligations, which is everything needed to give you a real figure rather than a brochure range. Most SMEs land in the Standard-to-Comprehensive band once 24/7 monitoring is included.
