  1. Cybersecurity
  2. SOC-as-a-Service
SOC-as-a-Service for US businesses

24/7 Security Operations Center, delivered as a service on Microsoft Sentinel.

Running your own security operations means three shifts of analysts, an enterprise log platform and runbooks that have been tested under real pressure. Almost no American mid-market business can justify that cost or attract those people. Buying it as a service produces the same outcome under one contract: monitoring around the clock, named engineers on call, a written response commitment and a report every month. It runs on Sentinel, ingesting from Microsoft 365, Azure, the endpoints, the network and identity, and it operates remotely inside your own tenant rather than ours.

What SOC-as-a-Service includes

Six operational SOC functions, monitored 24/7.

Security operations is not simply monitoring. It is monitoring alongside detection engineering, hunting, incident response, threat intelligence and reporting. Every function below is delivered by named analysts against a written commitment and reported on monthly.

24/7 alert monitoring and triage

Alerts triaged by front-line analysts inside five minutes for anything critical, ten for high priority and thirty for the rest. False positives suppressed at source, genuine ones escalated upward with the context already attached. A handover every shift with no gaps, covering every American time zone.

Detection engineering and tuning

The detection rules are tuned continuously against your environment rather than left as shipped. New ones get written from the intelligence feeds, from gaps in the attack technique coverage, and from whatever the last incident taught everybody. Suppressions get reviewed every month, because an unreviewed suppression is how a detection quietly dies.

Proactive threat hunting

A hunt every week, aimed at one specific hypothesis rather than at everything. Looking for evidence that credentials were dumped, say, or for outbound name resolution that has no business existing. Every hunt is documented, and whatever it finds either becomes a detection rule or gets investigated as an incident in its own right.

Incident response engagement

A critical incident brings immediate engagement. Contained inside an hour, forensic evidence preserved inside four, and a written review in your hands within five working days. Whatever your counsel and compliance function need for a breach notification is prepared alongside rather than requested afterward.

Threat intelligence and IOC ingestion

Sentinel ingests Microsoft Threat Intelligence, MITRE ATT&CK mappings, and curated external feeds. IOC blocklists pushed to your tenant continuously. Active campaign indicators, such as a ransomware group actively targeting US businesses in your sector, flagged proactively.

Monthly KPI and quarterly business review

Every month: what was detected and resolved, whether the response times were met, the alert categories that dominated, how dwell time is trending, and the coverage map. Every quarter: the roadmap, what the threat landscape has done, how effective the detection rules are proving, and where money would be well spent next.

Why security leaders route SOC through us

Four reasons US security leaders pick our SOC service.

Microsoft Sentinel as substrate, not bolt-on

Sentinel is our primary SIEM and the platform our security practice is built on, across a client base of 68+ active clients group-wide and 800+ systems under management. Native integration with Defender XDR, Entra ID, Purview, Azure, and Microsoft 365 means alerts have context that bolt-on third-party SIEMs lack.

Written priority-tiered SLA, service credits

Five minutes on a critical alert, ten on high priority, thirty on the rest. Service credits when any of those is missed. Real numbers written into the contract with real consequences behind them.

Remote-first, follow-the-sun coverage

The SOC operates remotely in your own tenant, around the clock. No hardware to host, no analysts to badge into your building, and nothing that stops working when your office does. Escalation paths, contact trees, and communication channels are agreed in writing at onboarding.

Audit-ready and insurer-ready reporting

Monthly reports written so they can be handed to a SOC 2 auditor, a HIPAA security officer, a NYDFS Part 500 assessor, or a cyber insurance underwriter as evidence of continuous monitoring. The report answers the questionnaire before it is asked.

Who needs SOC-as-a-Service

Six profiles where an in-house SOC is not viable.

Mid-market businesses

Too small to fund three shifts of analysts, and too large to leave security to somebody doing it part time alongside the help desk.

Financial services firms

NYDFS Part 500, GLBA, and FTC Safeguards expect demonstrable continuous monitoring; SOC-as-a-Service provides the evidence.

HIPAA-covered healthcare

Patient-data sensitivity requires 24/7 detection; an outage window during incidents is unacceptable.

Multi-location retailers

Wide attack surface across stores, e-commerce, and POS networks needs central monitoring.

Manufacturers with OT exposure

Where the plant floor network connects to corporate IT, monitoring has to extend into the operational technology zones as well. That matters directly to how CMMC scope is drawn for a defense supplier.

Cyber-insurance applicants

Underwriters increasingly ask for evidence of 24/7 monitoring; onboarding a service is faster than an in-house build-out.

How SOC-as-a-Service ramps

From a standing start to round the clock operations in eight weeks.

Onboarding runs to a structured eight week ramp. Sentinel goes in and gets tuned across the first three weeks. Front-line monitoring is live in week four. Detection engineering and hunting begin properly in week six. The first tabletop exercise and steady running follow from week eight.
  1. 1

    Sentinel deployment and log ingestion

    3 weeks

    Sentinel workspace deployed in your Azure tenant. Log sources connected: Microsoft 365, Defender, Entra, Azure, network, endpoints. Baseline detection rules applied. Initial false-positive suppression.

  2. 2

    Detection tuning and tier-1 activation

    2 weeks

    Detection rules tuned to your environment. Tier-1 analysts take operational ownership at week 5. SLA enforcement starts. Daily shift-handover protocol live. First weekly KPI report.

  3. 3

    Threat hunting and IR playbook

    2 weeks

    Weekly threat-hunt cycle begins. IR playbook authored, reviewed with your team. MITRE ATT&CK coverage map produced. First simulated tabletop drill.

  4. 4

    Steady state

    Continuous

    Steady-state operations from week 9. Monthly KPI reports, quarterly business reviews, periodic tabletop exercises, annual ATT&CK coverage refresh. Continuous detection engineering as the threat landscape evolves.

SOC-as-a-Service FAQ

What buyers ask before engaging.

SOC-as-a-Service is specifically the 24/7 monitoring, detection, and response function. Managed security services (MSS) is broader: SOC plus EDR, email security, identity protection, vulnerability management, awareness training, and compliance reporting. Many clients start with SOC-as-a-Service and expand to full MSS over time.

Yes. Sentinel is deployed in your Azure tenant under your subscription. All logs, detection rules, runbooks, and threat-hunt results stay with you. We operate it under delegated access. If you ever exit our service, the workspace and all data stay; you simply revoke our access.

Sentinel is billed by Azure on ingestion volume, so the Azure-side cost depends on how much log data you send. We help size and optimize ingestion (analytics versus data lake tiers, tuning noisy sources) to control that cost, and the SOC optimization discipline keeps it reviewed. Sentinel cost appears transparently on your own Azure invoice; our service fee is separate and quoted per engagement.

Our practice is Microsoft-native, and Sentinel is the SIEM we deploy and operate. It integrates natively with the Microsoft 365 tenant data most US mid-market clients already have, and it avoids data-egress charges to a third-party SIEM. If you have a significant existing SIEM investment, raise it on the scoping call and we will tell you honestly whether we are the right fit.

P1 (active attack in progress, business-critical system at risk): engagement within 5 minutes, containment within 1 hour. P2 (suspicious activity, contained impact): engagement within 10 minutes. P3 (low-severity alert, investigation needed): engagement within 30 minutes. Each tier has a documented SLA.

We provide the technical evidence pack, the incident timeline, and recommended notification content. The notification decision and submission go through your legal counsel and compliance function, because breach notification under HIPAA, state breach laws, NYDFS Part 500, or SEC disclosure rules is a legal obligation of your organization. We supply the facts that make those decisions fast and defensible.

Five core metrics: mean time to detect, mean time to respond, mean time to contain, false-positive rate, and MITRE ATT&CK coverage. Monthly reported, quarterly reviewed, with trend lines rather than snapshots so improvement or drift is visible.

Yes. Co-managed engagements are common: the in-house team handles strategy, vendor management, and business-aligned policies. Our SOC handles 24/7 operations. A RACI matrix is authored at onboarding so accountability is clear at the boundary.

Yes, entirely. The SIEM lives in your Azure tenant, monitoring and response are performed through delegated remote access, and communication runs through the channels agreed at onboarding. There is no hardware to install and no facility dependency, which is also why coverage does not degrade at night or over holidays.

It is designed to answer them. Underwriters and auditors ask for evidence of 24/7 monitoring, documented response times, and tested incident response. The monthly KPI report, the written SLA, the IR playbook, and the tabletop records are exactly that evidence. Your broker or auditor gets documents, not assurances.
