Managed cybersecurity: why a 24/7 SOC outperforms an in-house team
Building security in-house sounds like control. In practice, most companies end up paying more to cover fewer hours of the day.
The real cost of doing it in-house
Building an in-house security team isn’t hiring one person: it’s staffing a shift. Threat monitoring doesn’t run nine to five, so covering 24 hours a day, seven days a week, requires several analysts so no one has to stay awake every night of the month. A single specialist doesn’t cover a year: at best, they cover a third of the day.
On top of that comes the software. A SOC runs on three pieces you have to buy, integrate, and maintain: an endpoint detection and response platform (EDR/XDR), a SIEM to gather and correlate the alerts from all those tools, and the license for every source you want to watch. Most mid-sized companies end up buying part of this and leaving the rest uncovered — not out of neglect, but because the budget doesn’t stretch to all of it at once.
The typical result isn’t a company with no security. It’s a company with tools switched on that no one is watching at three in the morning.
What a SOC does that a single alert doesn’t
A security tool generates alerts; it doesn’t explain them. A managed SOC — a Security Operations Center — is the team and the process that turns those alerts into decisions: it classifies each one, filters out the noise, investigates the ones that warrant it, and responds to a real incident, instead of leaving someone on your team with an inbox full of unprioritized notices.
It’s worth separating the acronyms, because they get confused. The EDR/XDR lives on the endpoints and detects suspicious behavior. The SIEM is the hub that joins those signals with the rest of the network’s and correlates them. The SOC is the people and automation operating all of it around the clock. Having an EDR isn’t having a SOC, just as having an alarm isn’t having someone watching the cameras.
In our case that monitoring runs on Microsoft Sentinel as the SIEM, with three of our own AI agents — Triage, Report Generator, and Response Assistant — handling first-pass classification and report drafting, while human analysts focus on what truly requires judgment. In numbers, that translates into detection in under a minute, response in four, and 120,000 security alerts classified each month.
The nine layers: where the SOC fits
Security isn’t a product, it’s layers. We work with nine: human, identity, endpoints, network, applications, vulnerability management, data protection, threat intelligence, and data security. A SOC replaces none of them: it watches all of them. It’s the layer that notices when something, in any of the other eight, starts behaving differently.
That’s why the useful question isn’t “which tool do I buy?” but “who is watching what I already have?” Most companies already paid for more security than they use; what they’re missing is someone to operate it.
The question isn’t whether to hire, it’s when
No IT manager decides not to protect their company. Most simply don’t know which of those nine layers is most urgent in their case. That’s why a posture assessment, before a contract, is the sensible first step: it tells you what’s covered, what isn’t, and in what order to fix it. It commits you to nothing and brings order to the conversation.
Does this sound familiar?
If a single IT person at your company carries security on top of everything else, if no one reviews the alerts your existing tools already generate, or if the last time you talked about security was after a scare and not before, it’s time to look at this differently.
At Lynxsource we’ve run our own SOC since 2022, with our own analysts and automation, not a resold service. The first thing we do with a new client isn’t sell them a layer: it’s show them, with a free assessment, where they stand today.
FAQ
What exactly is a SOC?
A Security Operations Center is the team, processes, and technology that monitor an organization's security continuously: detecting, classifying, and responding to threats around the clock. It can be in-house or delivered as a managed service.
Is a managed SOC the same as reselling a third party's service?
Not necessarily, and the difference matters. At Lynxsource the SOC is our own: our analysts and automation, running since 2022, not another provider's console with our logo on it.
I already have antivirus and an EDR. Do I still need a SOC?
The EDR detects; the SOC operates. Without someone watching and responding to what the EDR reports, alerts pile up with no one deciding. The SOC is that decision, at all hours.
Is it cheaper than an in-house team?
For most mid-sized companies, yes, because it spreads the cost of several analysts and the platform across many clients. But the exact figure depends on your size and exposure: that's what the assessment estimates.
