Managed security (MDR) vs building an in-house SOC
An in-house SOC, or security operations center, means hiring, tooling, and staffing your own team to monitor and respond to threats around the clock. Managed security, often called MDR (managed detection and response), means an outside team does that for you. For most startups and scaleups, building a 24/7 SOC in-house is too slow and too expensive to justify. MDR gives you the same coverage without the headcount.
At a glance
In-house SOC | Managed security / MDR | |
|---|---|---|
What it is | Your own 24/7 security operations team | An outside team runs detection and response |
Cost | High: salaries, tooling, round-the-clock shifts | Predictable subscription |
Time to coverage | Months to hire and build | Weeks |
24/7 coverage | Only if you fully staff shifts | Built in |
Tooling | You buy and run it | Included or works with what you have |
Best for | Large orgs with scale and budget | Startups and scaleups needing coverage now |
What an in-house SOC involves
A real SOC is not one hire. It is a team large enough to cover nights and weekends, plus the detection and response tooling to run it, plus the process to triage and act on alerts. Done properly it is a serious, ongoing investment, which is why it usually only makes sense at real scale.
What managed security and MDR are
Managed security means an outside provider runs your detection and response. MDR focuses on the detect and respond core: watching your endpoints, cloud, and identity, triaging what fires, and containing real threats. You get continuous coverage and experienced hands without hiring, training, and staffing shifts yourself.
The real cost comparison
An in-house SOC carries the full weight of salaries, round-the-clock staffing, and tooling before it catches a single threat. Managed security turns that into a predictable subscription and gets you covered in weeks rather than months. For a startup, the gap in both cost and time to coverage is usually decisive.
When in-house starts to make sense
Building your own SOC becomes reasonable when you are large enough that the alert volume, the sensitivity of your data, or the control you need justifies the cost. Until then, managed security is how most teams get real coverage, and it plugs into an in-house team later just as well.
FAQ
What is the difference between MSSP, MDR, and SOC-as-a-service?
They overlap. MSSP is the broad term for outsourced security operations. MDR leans on detection and hands-on response. SOC-as-a-service is a managed team doing the monitoring for you. What matters is the outcome: someone watching, and someone acting when it counts.
Is MDR really 24/7?
Yes. Threats do not keep office hours, so coverage runs around the clock. An alert at 3am is triaged then, not first thing on Monday.
Do we need our own security tools?
Usually not. Managed security can run on the tooling you already have or recommend what fits, without locking you into a specific stack.
Do we still need our own security team?
No. Managed security is often how teams get real coverage before they hire in-house, and it works alongside an internal team once you have one.
