What is the difference between a SOC and a SIEM?

A SIEM is the platform that ingests logs, correlates events and generates alerts, while a SOC is the staffed shift that decides what each alert means. The gap is organisational: a platform can be switched on without changing how your team works, whereas a SOC needs a named owner for every escalation and a mandate to stop an attack. Subscription offers bundle both, so confirm whether analyst time is included in the price.

How do I verify a monitoring provider before signing?

Find out who actually staffs the shift: whether analysts are employed by the provider, whether night coverage is subcontracted, and which language escalation runs in after hours. Ask for references from an environment built on similar systems rather than from a company of similar headcount. Check whether a trial period is offered, so you can judge ticket quality against your own data before the service covers everything.

How does monitoring differ between a small company and a large one?

A small company usually connects a handful of sources, namely endpoints with EDR, the identity system and mail, and runs on the provider's standard detection content with light tuning. A large organisation adds in-house applications and several cloud tenants, so rules are written per system and part of the triage stays with an internal team. Splitting duties with your administrators then weighs more than the choice of platform.

Can we run security monitoring in-house?

Daytime monitoring is achievable in-house when someone knows the environment and maintains detection rules, but continuous coverage needs a shift roster that a mid-sized organisation rarely staffs. A middle path splits the clock: your team triages during business hours while a provider takes nights, weekends and public holidays. That model works only with one shared ticket queue and one agreed severity scale.

How often should detection rules be reviewed?

Detection rules need a review whenever something changes the shape of your event stream: a new application, a cloud migration, a different mail platform or a new administrative tool. Every incident and every alert closed as a false positive is another trigger, because both show that a rule is too narrow or too broad. Put that review into the contract as part of the service.

How do we know the monitoring is working?

The clearest signal is where you learn about an incident from: the provider, or your users and business partners. Watch the direction of MTTD and MTTR across successive reports, and the share of alerts closed as false positives, which should fall once tuning settles. The strongest evidence comes from a controlled test, an agreed action in your environment that proves an alert fires and reaches you.

What belongs in a SOC service SLA?

An SLA has to define severity classes and the moment the response clock starts, or each side measures it differently. Write down the scope of night and holiday coverage, the notification channel, and named contacts with deputies on both sides. Settle how far the provider may act on its own inside your estate, how new sources are added mid-contract, and which systems stay outside the service.

What happens to our logs and who can read them?

Logs handed to a monitoring provider carry personal data, account names and addresses, so the relationship needs a data processing agreement. Establish where the collection platform physically sits, how long it keeps events, and whether that retention matches your evidence needs. Ask which analysts open raw events, whether their access is recorded, and how data from higher-confidentiality systems is kept apart.

What mistake do buyers of monitoring make most often?

Buyers connect the sources that are easiest to wire up, the firewall and endpoint protection, while identity, mail and cloud consoles stay without logging. Monitoring then watches the network edge while an account takeover passes unseen. Handing over the environment without context costs as much: until the provider knows which administrative jobs are scheduled, it reports them as suspicious.

How long does it take to start monitoring?

Onboarding lasts as long as it takes to prepare each source for event collection and to secure the change windows in which those systems may be touched. Sources are connected in waves, critical systems first, so the first incident tickets arrive before the whole estate is covered. Tuning then runs against production data until the false positive load becomes manageable.

SOC services for businesses and 24/7 monitoring

A managed SOC gives your company a team of analysts who watch security events continuously and act on an attack before its effects reach your users. Events from servers, workstations, network devices, mail and cloud platforms flow into a SIEM, which correlates them and generates alerts from detection rules. An analyst triages each alert, discards the noise and escalates a genuine incident to named people on your side. SOC as a Service buys that capability on subscription instead of hiring a round-the-clock team.

The service covers log source onboarding, detection rules tuned to your environment, analyst coverage, incident triage and response guidance. Many providers add threat intelligence, meaning current campaign data and indicators of compromise, plus SOAR to automate repetitive response steps. You receive prioritised incident tickets with a narrative, periodic reports carrying MTTD and MTTR figures, an inventory of connected sources and documented detection logic. Under an MDR contract the provider also contains attacks, for example by isolating a compromised host or disabling an account.

Cost follows the number and type of connected sources, ingested data volume, coverage hours, the mandate the provider holds inside your systems and the response times written into the SLA. Delivery opens with a scoping workshop and an agreed source list, moves through onboarding and tuning against production data, and reaches steady state once the alert load becomes workable. What remains afterwards is standing work: adding sources, reviewing detection quality and reporting to whoever owns risk.

When to buy managed SOC monitoring

Nobody watches alerts outside office hours, so an attack detected on Friday evening waits for a response until Monday morning.
You already run EDR, firewalls and cloud logging, yet nothing correlates those signals or reviews them as they arrive.
A past incident showed that traces of the intruder had been sitting in your logs for weeks before anyone noticed.
A customer contract, an insurer or NIS2 obligations require documented detection and incident reporting within a defined window.
Your IT team receives more SIEM alerts than it can verify and has no capacity left to tune detection rules.

How to choose a SOC as a Service provider

Ask who writes and maintains the detection rules, and how often they are refreshed against techniques catalogued in MITRE ATT&CK.
Establish whether the provider only notifies you or also contains the attack, and what mandate it holds inside your systems.
Review the SLA in detail: alert acknowledgement time, time to reach a human analyst and the out-of-hours escalation path.
Request the list of supported log sources and an anonymised incident report from a real engagement rather than a template.
Clarify whose SIEM licence is used and what happens to collected data and custom detection rules once the contract ends.
