Managed Detection and Response
24/7 Managed Detection and Response
Managed Detection and Response (MDR) Services in Australia
Detection is not the hard part. Response is. Our Australian SOC analysts do not send you an alert at 3am and wait. They isolate the machine, kill the process, and call you once it is contained.
24/7 Managed detection and response (MDR) provides a security team that monitors your environment around the clock and has the authority to act the moment something is wrong. No triage queue. No waiting for business hours. No email that sits unread until Monday.
What is 24/7 managed detection and response (MDR)?
Managed Detection and Response (MDR) is a fully managed cyber security service that monitors your IT environment 24/7, detects suspicious activity, and responds to threats before they cause real damage.
Most Australian businesses already own security tools. There is an EDR agent on the laptops and a mail gateway in front of Microsoft 365. What they do not have is somebody reading what those tools are saying outside business hours.
That is what 24/7 MDR provides: security analysts who hunt for threats, investigate what the tools flag, and contain anything real as it happens, rather than the following Monday. Your team stays focused on the business.
Where MDR fits
MDR compared with what you may already have
| You have | What it does | What it does not do |
|---|---|---|
| EDR software | Detects malicious behaviour on endpoints and generates alerts | Read those alerts, decide which ones matter, or act at 3am |
| A SIEM | Collects and correlates logs from across your environment | Investigate, triage or respond. A SIEM is a tool, not a team |
| An MSP | Keeps your IT running and your users supported | Security monitoring. Most MSPs are not staffed or trained for threat response |
| 24/7 MDR from Borderless CS | Detects, investigates, and contains the threat | Nothing you need to chase separately |
MDR does not replace your EDR or your SIEM. It is the team that operates them. If you already own Microsoft Defender or Microsoft Sentinel, we work with what you have rather than asking you to buy it again.

Notifiable Data Breaches scheme
Assistance assessing whether an eligible data breach has occurred and support with the notification process.
ISO 27001 and SOC 2

Frequently asked questions
What is the difference between an MSSP and MDR?
An MSSP traditionally manages security tools and forwards alerts to you. MDR adds the response: the provider acts on the threat rather than telling you about it. We deliver both under one agreement, so the team that detects the incident is the team that contains it.
What is the difference between MDR and EDR?
EDR is software that detects suspicious behaviour on endpoints. MDR is the team that operates it, investigates what it finds, and responds. EDR without MDR is a smoke alarm with nobody home.
Do we need MDR if we already have Microsoft Defender?
Defender generates good alerts. It does not decide which ones matter, investigate them, or isolate a machine at 3am. We work with your existing Microsoft licensing rather than replacing it, and can usually improve what you already pay for before adding anything.
How much does MDR cost in Australia?
Pricing depends on user count, endpoints, log sources and platforms in scope. It is quoted as a fixed monthly fee. As a benchmark, an in house 24/7 capability requires five to six analysts to roster properly before any tooling is licensed. We will tell you on the first call if you do not need what we sell.
How quickly can you respond to an incident?
An analyst is working a critical incident within 15 minutes during business hours, and within one hour outside them. Containment actions are pre authorised during onboarding so there is no approval delay.
What can your analysts do without asking us first?
Exactly what you agree during onboarding, documented in writing. Most clients authorise endpoint isolation, process termination, account disablement and domain blocking. Anything outside those boundaries requires your approval, and you can change the boundaries at any time.
Will this help us meet the Essential Eight?
Directly, for the controls we operate: patch applications, patch operating systems, application control support, and multi factor authentication monitoring. We report monthly on your maturity level across all eight and identify what is required to move up a level.
Do you monitor cloud environments as well as on premise?
Yes. Microsoft 365, Azure and AWS are monitored alongside on premise infrastructure in a single view. For most of our clients, identity and cloud are now where the majority of detections originate.
What size organisation is this suited to?
Our clients typically sit between 50 and 1,000 staff. Below 50, we usually recommend starting with an assessment and Essential Eight uplift before committing to full managed monitoring. Above 1,000, we generally deliver a co managed model alongside an internal security team.
Are you Australian owned?
Yes. Borderless CS is Australian owned and operated with offices in Melbourne, Sydney, Brisbane and Perth.
