SOC as a Service: Coverage, Response & Pricing
A useful security monitoring service needs more than logs in a console. It needs the right sources connected, an investigation process and someone authorized to act on the findings. NetSys scopes SOC monitoring around those requirements, including the data, coverage, escalation and costs your business can evaluate.
The short answer
SOC as a service is a security operations center you subscribe to instead of building: a provider collects your security logs into a SIEM, watches them around the clock, investigates what looks wrong and escalates or contains the real findings. NetSys scopes which sources are connected (sign-in, endpoint, email, firewall and server logs), the escalation path and the actions we may take, and the price follows those sources, the data volume, retention and the response work included. Monitoring, containment, incident response and recovery are related but separate commitments, so the agreement says which ones you are buying.
Two SOC quotes can cover different environments even when they list the same number of users. One may include identity and email data while another depends on endpoint alerts alone. A source that cannot connect, stops reporting or lacks the required license creates a visibility gap. Establish the inventory and prerequisites before treating the quoted service as active coverage.
Decide what should happen when a finding needs action. An investigation can produce a recommendation, a call to your contact or an authorized containment action. Those are different commitments with different access requirements. The agreement should also identify the handoff when a case needs a broader incident investigation or business recovery.
Connect the sources and validate the escalation path
We scope source discovery and platform access, establish the agreed connections and record limitations. Onboarding validates that expected data arrives and that cases reach the right contacts. The operating plan identifies tuning, source-health checks, retention and reporting responsibilities. Material changes to systems or log volume should trigger a coverage and cost review rather than silently expanding the service.
SOC coverage and quote inputs to define
Sources and data availability
Start with the systems whose activity needs review.
- Identity, email, endpoint, server, network and cloud sources proposed for connection
- Supported integrations, permissions, licensing and any unavailable telemetry
- Source-health checks and responsibility when data stops arriving
- Documented scope boundaries for devices and systems outside coverage
Platform cost and retention
Separate monitoring labor from the data platform and its usage.
- Expected ingestion volume, retention and retrieval needs
- Existing platform entitlements, selected data plans and applicable usage charges
- A baseline estimate with assumptions and a process for reviewing material growth
- Ownership of the tenant or workspace and access to records when support changes
Investigation and authorized response
A finding needs a clear decision and escalation route.
- Coverage hours, severity definitions and investigation expectations
- Primary and backup contacts for urgent business or technical decisions
- Permitted containment actions, prerequisites and exceptions documented in advance
- Handoffs to internal IT, incident response, vendors and recovery owners
Reporting and continuing review
Show what was covered and what still needs work.
- Material cases, actions, unresolved findings and source-coverage gaps
- Detection tuning and changes recorded against the environment
- Agreed evidence and retention requirements rather than assumed regulatory sufficiency
- A review cadence and owners for follow-up remediation

What a SOC service level should spell out
Buyers asking for detection and response SLAs are really asking for these terms in writing. Compare them across proposals, including ours:
| Term | What the agreement should say | Why it matters |
|---|---|---|
| Coverage hours | When people or automation review activity, and what happens outside those hours | An alert is only useful if someone is covering the hour it fires |
| Severity levels | Plain definitions of critical, high and routine findings, with examples from your environment | Severity decides who is called and how quickly |
| Acknowledgement and escalation | Target times to acknowledge a finding and reach your named contact, per severity | This is the figure buyers compare, so it belongs in the contract |
| Containment authority | Which actions the provider may take without asking, such as isolating a device or disabling an account | Pre-approved actions start sooner than a call chain |
| Source health | How a silent log source is detected and who fixes it | A source that stops reporting is a blind spot, not a quiet night |
| Reporting and retention | What each report shows and how long records are kept | Evidence for insurers, auditors and your own reviews |
Ask for each of these in writing, from us or from any provider. Phone and remote response commitments for managed clients are in the response-time table on our managed IT services page.
Log sources and what each one catches
A SOC sees only what is connected to it. The usual sources for a small business, with examples of what each shows:
| Source | Examples of what it shows | Why it matters |
|---|---|---|
| Sign-ins (Entra ID) | A sign-in from a country your staff does not work in or over legacy authentication, a replayed session token, repeated denied MFA prompts | Where a stolen password or session shows itself |
| Email (Microsoft 365) | A new inbox rule quietly forwarding mail outside the company, an OAuth app consent nobody asked for | Where phishing and payment-fraud attempts arrive |
| Endpoints and servers | Credential dumping, new admin accounts, backup service tampering, mass file renames | These are the precursors of ransomware |
| Firewalls and VPN | Admin changes, blocked threats and remote-access sign-ins | Firewalls and VPN appliances are among the first devices attackers scan for |
Ingestion costs differ by source. In Microsoft Sentinel, for example, data is billed by volume with the first 90 days of retention included, and some Microsoft security alerts and Office 365 audit logs are free to ingest while raw sign-in and endpoint logs are not, per Microsoft's pricing guidance as of October 2026.

24/7 SOC Monitoring FAQs
How much does SOC as a service cost?
A useful quote needs the source inventory, approximate daily log volume, retention requirements, existing licenses, service hours and expected investigation or response work. Separate platform ingestion and storage charges from service fees and onboarding: in Microsoft Sentinel, for example, data is billed by volume, retention beyond 90 days costs extra, and commitment tiers start at 100 GB a day, as of October 2026. Ask what changes the price and what is included in any existing agreement. A per-user figure alone cannot describe every SOC scope.
What is the difference between SOC monitoring and MDR?
SOC describes an operating function or service that reviews security activity. MDR describes managed detection, investigation and response, and can extend beyond endpoints depending on the provider and tools. Their coverage may overlap. Compare actual sources, analysts or automation involved, response authority and incident handoffs instead of treating MDR as endpoint-only or SOC as automatically broader.
Do we need another service if we already use Microsoft Defender?
First identify the exact Defender products, licenses and configured sources. Microsoft security products can correlate activity across supported workloads; owning them does not by itself establish who reviews findings or performs authorized response. Determine which gaps are technical, operational or coverage-related before adding another platform or service.
What happens to a serious finding outside business hours?
The agreement should specify coverage and the escalation route for that situation. Any action such as isolating a device or disabling access requires appropriate tools and authority. Name backup contacts and the handoff when a case exceeds the monitoring scope. An after-hours alert does not guarantee that containment or resolution will be immediate.
Does longer log retention prove compliance?
No. Retention is one requirement to evaluate alongside the relevant controls, access, evidence and procedures. Identify the records actually needed, the system producing them and the ability to retrieve them. A retention setting or SOC report alone does not establish compliance or guarantee acceptance by an insurer or reviewer.
What is SOC as a service?
SOC as a service is a security operations center you subscribe to instead of building: a provider collects agreed security logs, investigates suspicious activity and escalates real findings to your contacts. It suits businesses that need monitoring and investigation but cannot staff analysts around the clock. What it covers depends on the connected sources and the agreed response authority.
What is a managed SOC?
A managed SOC is the same service described from the provider's side: an outside team runs security monitoring and investigation for you, sometimes inside a workspace your business owns. Some managed SOC offers include containment actions, while others stop at escalation. Ask which sources are connected, who reviews alerts and which actions the provider is allowed to take.
What is managed SIEM?
A SIEM collects security logs from many systems and correlates them, so a suspicious sign-in, a new inbox rule and an alert on a laptop can be read as one story. Managed SIEM means a provider runs that platform for you: connecting sources, tuning detection rules, checking that sources keep reporting and managing retention and cost. SOC as a service adds the people who investigate and act on what the SIEM finds, and the two are usually bought together.
What is included in SOC as a service?
At NetSys: discovery and connection of the agreed sources; 24/7 monitoring and triage of what they report; investigation of findings; escalation to your named contacts by severity, with backups; containment within the actions you pre-approve, such as isolating a device or disabling an account; checks that each source is still reporting; detection tuning; and reports showing material cases, actions, open findings and coverage gaps. Retention, platform charges and incident response beyond the agreed scope are listed separately.
How does SOC onboarding work?
It starts with source discovery: which identity, email, endpoint, server, network and cloud systems can be connected, with what permissions and licenses, and which cannot. The agreed sources are connected, and onboarding checks that the expected data actually arrives and that a test case reaches the right contacts. The operating plan then records tuning, source-health checks, retention and reporting, and any limits are written down before the service is treated as active coverage.
Who handles support and escalations?
NetSys monitoring runs 24/7. A real finding is escalated to your named contacts in the order and by the severity the agreement sets, with a backup for each, and containment is limited to the actions you approved in advance. A case that grows beyond the monitoring scope is handed to incident response. Questions about the service and its reports go to the help desk, staffed seven days a week from 4 a.m. to 11 p.m. Eastern.
