Managed security
A SIEM nobody reads
is an expensive diary.
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.

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
It’s in the budget. Nobody’s in front of it.
SIEMs get sold as security products and delivered as plumbing projects. The gap between those two is where the money went.
- The firewall logs made it in. The identity provider, the one that would have shown the login from the wrong country, didn’t.
- Half your sources arrive as one long unparsed string, so the search that should find it finds nothing.
- Ingest is billed by volume, and “should we collect this?” has quietly turned into “can we afford to?”
- The detection rules are the vendor’s defaults, written for a network the vendor has never seen.
- Retention got set to whatever the license allowed. That turned out to be shorter than the breach.
What we do instead
It’s a data problem first, so we treat it like one
Before anyone writes a rule, we work out which logs would actually show the attacks you care about. Those sources come in first, parsed into fields you can search. Then comes the tuning, and every rule that fires gets a verdict. Either it means something and someone acts on it, or it’s rewritten or retired. What’s left is a console an engineer reads every day, because it’s finally worth reading.
How it works
How we build a SIEM and keep it useful
Most vendors sell you step three and skip everything around it.
Start from the questions
Who signed in from where? What ran on which server? What left the network? We list the sources that answer those first. Collecting everything is how the bill gets big and the signal gets small.
Get the sources in, parsed
Identity, endpoints, firewalls, cloud control planes, and whichever application holds your customer data. Each lands as structured fields, and a source that goes silent raises its own alert.
Match retention to the question
Hot storage for what an investigation reaches for daily. Cheap cold storage for what an insurer or regulator asks about a year later. Keeping a log should be a line on the storage bill, never a budget meeting.
Tune until alerts are worth reading
In the early weeks, every rule that fires gets reviewed: keep, rewrite or retire. Triggers and thresholds are written down, and the enrichment someone used to do by hand runs in software before the alert is raised.
Analyze in real time, for good
Correlated alerts reach an engineer with the context attached. The ones that need containment go straight into the response process. And the rule set keeps changing as your business does.
What managed SIEM covers
Setup and source coverage
Identity, endpoints, Windows and Linux servers, network gear, cloud control planes and the applications your business runs on, on premises or in the cloud. We map what’s missing against what an attacker would touch first.
Parsing you can search
“Every admin sign-in outside working hours from a new device” should be a search, not a project. Every source lands as fields, and one that changes format upstream breaks loudly.
Retention that fits the question
Storage tiered to what an investigation, an insurer and a regulator each need to see, so cost is never the reason a log got thrown away.
Tuning on a schedule
Rules are checked against what they actually fired on. Noise gets retired, gaps get written, and the change log says who changed what, and why.
Real-time analysis, with an engineer behind it
Correlation runs in software, with the trigger and the action agreed in advance. Anything that needs judgment reaches a person with the evidence already attached.
Your SIEM, in your tenancy
Rules, parsers and pipeline live as code in a repository on infrastructure you own. If we ever part ways, the SIEM keeps working and the rules stay with you.

Security Operations Center (SOC) as a Service
Round-the-clock monitoring of your network alerts, 365 days a year, with triage and escalation built in. Automation reads each alert the second it lands, so the watch never depends on who happens to be awake.
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.
Incident Response & Digital Forensics
Immediate containment, breach investigation and evidence gathering while the attack is still underway. Set it up as a retainer and your first call is a call, not a contract negotiation, and the cleanup won’t destroy the proof you’ll need later.
What’s going in, and what’s it costing you?
Your current log sources, your last ingest bill, and the last alert anyone acted on.
Share those and we’ll tell you what’s missing, what’s noise, and whether the SIEM you’ve got is worth keeping or worth replacing.
