Cybercriminals do not wait for business hours. The majority of ransomware deployments and network intrusions happen at night, on weekends, and during holidays, precisely the hours when most internal security teams are offline. For a mid-market company with two or three IT generalists, "24/7 monitoring" is not a staffing gap. It is an impossibility.
The math is unambiguous. A week has 168 hours. One analyst covers approximately 40. Keeping a single monitoring seat staffed around the clock, accounting for nights, weekends, holidays, sick time, vacation, and training, requires a team of 10 to 12 people, at an average salary of $65,000–$130,000 each, plus SIEM and SOAR tool licensing at $200,000–$500,000 annually, plus a SOC manager, a facility, and the ongoing overhead of recruiting in one of the tightest talent markets in enterprise technology (KORE1, July 2026). Building a capable in-house SOC costs $1.2M–$4M+ per year. Most mid-market organizations cannot justify that cost while maintaining every other security and IT function they need to operate.
SOCaaS, Security Operations Center as a Service, is the model that closes this gap. Instead of building the capability internally, organizations subscribe to a provider's round-the-clock security operations: the analysts, the tooling, the threat intelligence, and the incident response. The provider's SOC is shared across many clients, making enterprise-grade coverage economically viable for organizations that could never fund it alone.
The staffing reality
"Attacks do not keep office hours. Most security teams do. Round-the-clock monitoring means trained analysts on every shift, and those analysts are scarce, expensive, and quick to burn out. Many mid-sized companies stopped trying to build a SOC and started renting one."
Section 1: What SOCaaS Actually Is, and What It Is Not
SOCaaS is a subscription-based cybersecurity service that delivers continuous threat monitoring, detection, investigation, and incident response through a managed Security Operations Center operated by a third-party provider. The client organization connects its IT environment, endpoints, network devices, cloud platforms, email, applications, and, where relevant, OT systems, to the provider's monitoring platform. The provider's analysts watch the data 24 hours a day, 7 days a week, 365 days a year.
SOCaaS is not the same as security software. A firewall, an endpoint detection tool, or a SIEM platform generates alerts, but alerts require human interpretation, prioritization, and action. SOCaaS provides the human layer that turns alerts into investigated, contextualized, and responded-to incidents. The tools generate the signal. The SOC analysts determine what it means and what to do about it.
Three delivery models exist, and choosing the right one depends on how much internal security capability your organization already has:
| Model | How it works, and who it fits |
|---|
| Fully Managed SOC |
The provider owns end-to-end security operations: monitoring, detection, investigation, containment, and reporting. Best for organizations with no dedicated internal security team, or teams under five people who need immediate 24/7 coverage. |
| Co-Managed SOC |
The provider handles 24/7 monitoring and Tier 1–2 triage; the client's internal team retains strategic control, detection rule ownership, and Tier 3 investigations. Suited to organizations with 5–15 security staff who want operational leverage without surrendering governance. |
| Hybrid SOC |
Internal team covers business hours; the provider handles nights, weekends, holidays, and surge capacity. Works well for teams that can staff the day shift reliably but cannot sustain overnight coverage without burning people out. |
For most commercial real estate and multifamily organizations, which typically operate with IT generalists rather than dedicated security teams, the fully managed model is the relevant one. There is no internal security function to co-manage. The SOCaaS provider becomes the security operations function.
Section 2: How a 24/7 SOC Actually Works — The Five Layers
Understanding what a SOCaaS provider does operationally helps organizations evaluate providers and set realistic expectations for what the service delivers. The five layers below describe the operational model of a credible managed SOC.
1
Telemetry Collection and Ingestion
The SOC begins with visibility. The provider connects to the client's environment through agents on endpoints, API integrations with cloud platforms and SaaS applications, network sensors, and log forwarding from firewalls, servers, and identity systems. For CRE and multifamily operators, this also means connecting to building management systems, access control platforms, and IoT device networks, the OT layer that most general-purpose IT security providers do not extend coverage to. All of this telemetry flows into the provider's SIEM platform, which normalizes and correlates data from disparate sources into a unified view of the client's security environment. The quality of a SOCaaS provider's monitoring is directly limited by the completeness of its telemetry.
2
Detection: Turning Data Into Signals
The SIEM platform applies detection rules, behavioral baselines, threat intelligence feeds, known attack signatures, and anomaly detection models to the incoming telemetry. A mature SOCaaS provider maintains a library of detection rules tuned to the specific threat landscape of their client industries, not just generic MITRE ATT&CK coverage. Detection quality is where providers differentiate significantly. A high-volume alert environment, one generating 960+ alerts per day, the average for understaffed SOC teams (UnderDefense, April 2026), is not a sign of superior detection. It is a sign of untuned detection rules producing noise that overwhelms the investigation capacity of the team.
3
Triage and Investigation: Determining What Is Real
When an alert fires, a human analyst investigates. Tier 1 analysts perform initial triage: is this a false positive, a known benign behavior, or a genuine threat requiring deeper investigation? Tier 2 analysts investigate confirmed or likely threats in depth: scope, affected systems, attacker objective, appropriate containment response. This is the layer that separates SOCaaS from security tools. Tools produce alerts. Analysts produce verdicts. The mean time to detect (MTTD) for best-in-class SOCaaS is under 11 minutes (N-able, April 2026). Organizations managing alerts manually, or not at all, typically measure dwell time in days or weeks.
4
Response and Containment
Once a threat is confirmed, the SOC takes action. The scope of response authority depends on what the client has agreed to in the service contract: some clients authorize the SOC to act immediately (isolate an endpoint, block an IP, revoke a compromised credential); others prefer notification first, with the client team executing the response. For mid-market organizations without dedicated incident response capability, authorizing the SOC to take containment actions directly is typically the more protective option; every minute between detection and containment is time the attacker can use to move laterally or exfiltrate data.
5
Reporting, Review, and Continuous Improvement
The SOC produces regular reporting: daily or weekly security summaries, incident reports for significant events, monthly trend analysis, and compliance reporting where required. Scheduled review sessions between the SOC team and the client allow detection rules to be refined, new threat vectors to be added to coverage, and the client's risk posture to be assessed over time. A credible SOCaaS engagement is not a static service; it improves as the provider learns the client's environment and the threat landscape evolves.
What most CRE organizations are missing
General-purpose SOCaaS providers monitor IT environments: endpoints, email, cloud applications, and corporate networks. Most do not extend monitoring to building automation systems, IoT devices, BMS controllers, or the OT networks that increasingly define the attack surface in commercial real estate. A 24/7 SOC that covers only the IT side of a CRE organization leaves the building systems layer, where some of the most consequential attacks now originate, completely unmonitored.
Section 3: The Cost Reality — What In-House Actually Costs vs. SOCaaS Pricing
The most common objection to SOCaaS is cost. The most common mistake is comparing the SOCaaS monthly subscription to a single analyst salary, rather than to the full cost of building the equivalent capability internally. The comparison looks very different when the full cost of an in-house SOC is calculated honestly.
| Building in-house (annual cost) |
SOCaaS equivalent |
| 10–12 SOC analysts at $65K–$130K base = $650K–$1.56M in salaries alone |
SOCaaS: $10–$60/endpoint/month. Most mid-market organizations pay $15–$30/endpoint for comprehensive coverage (UnderDefense, April 2026) |
| SOC manager: $120K–$150K annually |
No management overhead, included in the subscription |
| SIEM / SOAR / XDR licensing: $200K–$500K annually |
Technology stack included in SOCaaS, no separate licensing |
| Recruitment, onboarding, and turnover costs: SOC analyst turnover averaged 28% in 2024 |
No recruitment exposure; provider absorbs staffing and retention costs |
| Total in-house cost: $1.2M–$4M+ per year before facility and overhead |
Total SOCaaS cost: $10K–$150K+ per year depending on endpoint count and scope |
The total cost of building equivalent in-house SOC capabilities runs to $2.7M+ annually in direct labor costs alone before tooling, facility, or management overhead (N-able, April 2026). For a mid-market organization with 200–500 endpoints, a well-scoped SOCaaS engagement typically runs $25,000–$75,000 annually. The economic case is not close.
The second cost consideration is the cost of not having coverage. IBM's 2024 Cost of a Data Breach Report put the global average breach cost at $4.88 million, and organizations with understaffed security teams and no 24/7 coverage experience dwell times three times longer than those with continuous monitoring, directly increasing breach severity and cost. The cost of inaction is quantifiable, and it dwarfs the cost of the subscription.
Section 4: Five Questions to Ask Before Choosing a SOCaaS Provider
Not all SOCaaS providers are equivalent. The five questions below are the ones that separate providers with genuine operational depth from those reselling basic alert monitoring with a 24/7 label.
Question 1
Does your SOC cover OT environments and building systems, or only IT?
General-purpose providers monitor endpoints, email, and cloud. A CRE or multifamily organization needs a provider whose monitoring extends to BMS controllers, IoT devices, and building automation networks. Ask specifically which OT protocols and device types the provider can ingest telemetry from.
Question 2
What is your mean time to detect (MTTD) and mean time to respond (MTTR)?
Best-in-class SOCaaS achieves an MTTD of under 11 minutes. Ask for documented benchmarks from the provider's current client base, not marketing claims. If MTTD is not tracked and reported, it is not being managed.
Question 3
What response authority does the SOC have, and what does it need client approval for?
Understand the division of responsibility before an incident occurs, not during one. For organizations without internal incident response capability, the SOC should have pre-authorized containment authority for defined incident types.
Question 4
How are detection rules tuned for your specific environment and industry?
Generic detection rules produce alert noise, high volumes of low-signal alerts that exhaust analyst capacity and create false confidence in monitoring. A provider that can describe how they tune detection logic for CRE-specific threats (BMS anomalies, wire fraud indicators, property management platform access patterns) is a provider with genuine vertical expertise.
Question 5
What compliance reporting does the SOC produce, and for which frameworks?
CRE and multifamily operators face obligations under state breach notification laws, FTC Safeguards Rule requirements, cyber insurance policy conditions (MFA verification, backup testing, security awareness training documentation), and in some cases SOC 2 Type II requirements for enterprise tenant relationships. Confirm the provider can produce documentation relevant to the frameworks that apply to your organization.
