How much do managed security services cost in Australia?

At the lightest end, a business that already has IT support or in-house staff adds a dedicated security layer on top: managed monitoring of Microsoft 365 and email security, plus staff security-awareness training. Published Australian pricing for this add-on sits around $75 to $100 per user per month, and it does not replace a helpdesk or general IT support, it sits alongside it.

The standard tier, quoted at roughly $120 to $250 per user per month by Australian providers, is usually bought as part of a broader managed-IT contract rather than standalone. It adds endpoint detection and response (EDR) and email security monitoring to the general support already included, and is the most common arrangement for small and mid-sized Australian businesses.

A security-first or regulated-industry tier, generally $200 to $350 per user per month, adds 24/7 managed detection and response (MDR), alignment with the Australian Cyber Security Centre's Essential Eight framework, and compliance support for standards such as APRA's CPS 234, ISO 27001 and the Privacy Act. A named virtual CIO for security strategy is typically included at this level. Businesses in financial services, health and legal are the most common buyers here, usually because a regulator, insurer or client contract requires it.

One anonymised Australian provider proposal from April 2026 (published July 2026) shows what this actually looks like invoiced: managed Microsoft 365 security monitoring at $75 per user per month, managed cyber security awareness training at $9 per user per month, a quarterly phishing simulation at a fixed $125 per month, and managed security reporting at a fixed $150 per month. Across a 130-user business, the monthly subtotal was $11,195, excluding GST, equivalent to roughly $86.12 per user. Cyber incident response outside the standing agreement was billed separately at $250 per hour.

The provider that published it was explicit about the limits of a single example: it is one real proposal, not a market average, a fixed package, or a promise of what another environment will cost. It is included here for exactly the reason msppie exists, to show a real number from the market rather than one provider's own generic rate card.

These three get requested almost interchangeably, and picking the wrong one is the most common way an enquiry ends up mismatched to a quote.

General managed IT support (see msppie's IT support cost per user guide) is the helpdesk, patching and device management a business needs day to day, with a baseline of security bundled in at every tier. Most businesses buying managed security services are already paying for this, or run it themselves.

Managed security services, the subject of this guide, are the security-specific layer on top: monitoring, detection and response, and compliance support, bought either as an add-on to existing IT support or as the security-heavy tier of a combined contract.

A cyber security audit or penetration test (see msppie's cyber security audit cost guide) is a one-off, point-in-time engagement, a report on where you stand today, not an ongoing service. Many businesses buy an audit first to find out what a managed security service then needs to cover.

Four factors explain most of the spread between a $90 quote and a $300 quote for what a buyer might describe the same way.

Existing coverage matters first. A business that already has full IT support and only needs the security layer pays toward the bottom of the range; a business buying security bundled into a brand-new managed-IT contract sees the fuller, blended figure.

Regulatory obligation matters second, and it is the single biggest driver of the top tier. A published worked example for a 100-staff Australian financial-services business needing APRA's CPS 234 and managed detection and response priced at $20,000 to $32,000 a month, $200 to $320 per user, well above an unregulated business of the same size.

Coverage hours matter third. Business-hours-only monitoring sits at the bottom of a tier; moving to 24/7 managed detection and response is the single biggest driver of moving from standard to security-first.

Headcount matters fourth, in the same direction as general IT support: smaller businesses typically sit nearer the top of a tier's per-user range, because a provider's fixed monitoring and reporting overhead spreads across fewer users.
