Most breaches are not clever. An attacker signs in with valid credentials out of hours and looks around for days. Managed Detection and Response puts human analysts and 24x7 monitoring across your endpoints, identities, network and cloud, so that quiet activity is caught while it is still one account.
The problem
Endpoint protection deals with known, automated threats, and it does that well. What it does not deal with is a person using valid credentials taken from a convincing phishing page, because nothing about that looks like malware.
That is the pattern behind most of the incidents Australian organisations suffer: legitimate access, out of hours, moving quietly until something is worth taking. Detecting it means watching behaviour across the whole environment and having someone awake to judge what they are seeing.
Laptops and servers, watched for the behaviour that follows a compromise rather than only the file that started it.
Sign-ins, privilege changes and token abuse across Microsoft 365 and your directory, the surface most attacks now use.
Traffic and lateral movement between systems that should have no reason to talk to each other.
Configuration drift and access anomalies in the platforms your business now actually runs on.
Straight answers
Three terms sold interchangeably. The differences matter when something is actually happening.
| What it means | What you get | The catch | |
|---|---|---|---|
| MDR | Detection and response delivered as a service | Threats found, triaged and contained for you | Scope varies wildly between providers, so ask what is actually monitored |
| SOC | The team and facility doing the work | Analysts watching, around the clock | A SOC with no mandate to act can only tell you afterwards |
| MSSP | Managed security services, broadly | Security tooling run on your behalf | Often alert forwarding rather than response |

What happens
Minutes
Behaviour across endpoint, identity, network and cloud is correlated. A single odd sign-in is noise, the same sign-in followed by a privilege change is not.
Minutes
An analyst decides whether this is a threat, not a rule acting alone. False positives are the reason most in-house monitoring gets switched off.
Same hour
The account is disabled, the device isolated, the session revoked. Containment happens while the investigation continues rather than after it.
Next day
You get what happened, what was done, and what would stop it recurring, in language a board can read.
Around it
Continuous vulnerability scanning and exposure profiling, so you are closing the doors rather than only watching them.

With REDD it covers endpoint, identity, network and cloud, monitored 24 hours a day by analysts in a Security Operations Centre. Coverage is the question to ask any provider, because MDR that watches endpoints alone will miss the identity attacks that are now most common.
Endpoint tools detect malicious software. MDR adds people and correlation across your whole environment, which is what catches an attacker using valid credentials and no malware at all. The tooling is part of MDR, not a replacement for it.
Response is the point. Accounts are disabled, devices isolated and sessions revoked while the investigation continues. A service that only forwards alerts to your inbox at 2am has moved the problem rather than solved it.
Increasingly the two are linked. Insurers ask what monitoring and response you have, and the answer affects both the premium and whether a claim is paid. Cover pays for the damage, detection is what reduces it.
A REDD security engineer will walk through what you monitor today, where the blind spots are, and what it would take to close them.
