Managed security
Three harmless events.
One break-in.
XDR correlates what your endpoints, email, cloud workloads and network each see, so signals that look harmless alone get read together. Think of it as the layer above EDR, joining its dots to everyone else’s.

Every one of our people holds active certifications on the platforms they work on.
Sentrello is our only partnership. On the clouds, it's our people who hold the certifications. We don't claim a partner tier, and we'll keep saying so until that changes.
Where this usually starts
Four consoles. Four green ticks. One intruder.
Ask any of your security tools and it’ll tell you its corner is fine. None of them can see the corner next door, and the attacker walked through all four.
- A sign-in from a new country? Nothing. A new forwarding rule and a bulk download in the same hour? Something. No tool joined them.
- Endpoint, mail, cloud and firewall each keep their own clock, and each spells the same user differently.
- Your analyst has eleven tabs open and is correlating in their head, using whichever alerts they happened to catch.
- The post-incident review always finds the early warning, sitting in a dashboard nobody had a reason to open.
- Each new tool arrived with a new console, and the list of places to look just got longer.
What we do instead
One timeline, and rules that read across it
Every layer’s signals land in one place, on one clock, tied to one identity per person. So the sign-in, the mailbox rule and the download stop being three tickets in three tools and become one entry under one name. The correlation rules then do what your analyst was doing in their head, for every user, all the time. EDR watches the machine. XDR watches the machine, the mailbox, the cloud tenant and the network together, because that’s how an attacker uses them.
How it works
How correlation works
Step three is where the incident shows up. The two before it are why it can.
Bring every layer in
Endpoint telemetry, mail flow and mailbox audit logs, cloud sign-ins and workload logs, firewall and DNS. From whichever vendors you already run. You don’t have to rip anything out for us to read it.
Agree on who and when
One identity per person across every source, one timezone, one name per machine. Plenty of correlation projects die right here, quietly, because the same person is four different strings in four tools.
Correlate the chain
The rules look for sequences rather than single events. New-country sign-in, then a forwarding rule, then a download. Not one of those fires alone. The chain fires as an incident with all three attached, and every rule has its reasoning written beside it.
Respond where it’ll work
Sometimes that’s isolating the laptop. Sometimes it’s revoking the cloud session, deleting the mailbox rule or blocking an address at the edge. The response goes to whichever layer stops it, under a containment policy you agreed in advance.
Learn from every incident
Each review asks one question: which chain should have fired sooner? That chain is a rule before the review closes. It’s why adding another source makes the system sharper rather than louder.
What correlation covers
Four layers, one timeline
Endpoints, email, cloud workloads and network. Any EDR, any mail platform, AWS, Azure, Google Cloud or DigitalOcean, and any firewall that can write a log.
One identity per person
Every source mapped to the same user and the same machine, so a chain across layers actually looks like a chain. Getting this right is most of the work, and most of the value.
Chain rules, not event rules
Detections written as sequences across sources, with the logic documented next to each one. If a chain fires on Tuesday, you can read why it was written on Monday.
Response in the right place
Isolate the endpoint, kill the cloud session, remove the mailbox rule, block at the edge. Whichever cuts the attacker off, within the containment policy you already hold with us.
Where XDR sits
EDR is the sensor on the machine. MDR hunts through that sensor and acts on what it finds. XDR reads every sensor at once, and it works alongside whichever of the other two you already have.
An incident on one page
Every signal in order, each with its source. When your insurer or your board asks what happened, the story is already written.
Related
Endpoint Detection & Response (EDR)
Continuous monitoring of every laptop, desktop and server for behavior that looks like an attack, whether anyone’s seen that particular malware before or not. It’s the sensor the rest of your security runs on.
Managed SIEM
We set up your SIEM, aggregate the logs that matter into it, and analyze them in real time. Most SIEM projects fail as plumbing long before they fail as security, so the plumbing is where we start.
Managed Detection & Response (MDR)
Active threat hunting through your endpoint data for the intruder no alert caught, and a fast response the moment we find one. The SOC watches what fires. MDR goes looking, with your written permission to act.
Which layers can you see today?
Your endpoint tool, your mail platform, your cloud tenant and whatever guards the network edge.
Once we know those four, we can show you the chains you’re currently blind to, what joining them would take, and which of your existing tools we’d keep reading from instead of replacing.
