SOC-as-a-Service, often overlapping with managed detection and response, outsources round-the-clock security monitoring, threat detection, alert triage and response to a provider's security operations centre. Engagements cover telemetry ingestion across endpoint, network, identity and cloud, detection engineering, threat hunting and incident response, usually billed per endpoint or per user. TechVendorIndex tracks nine providers, from concierge SOC operators that manage your tooling to platform-native services built on a vendor's own detection stack. One structural change shaped the market in 2025: Sophos completed its acquisition of Secureworks in February, consolidating the Taegis platform. Typical buyers are CISOs and IT leaders that need 24/7 coverage without building an in-house team. No provider pays for placement on this directory.
Providers differ most in their delivery model and in who owns the data. Concierge operators such as Arctic Wolf manage a security-operations layer over your environment and assign a named team, which suits mid-market buyers wanting an outsourced programme. Transparency-led providers — Expel and Red Canary — emphasise co-management and full visibility into analyst actions, and Red Canary is notably agnostic about which endpoint tool you run. Platform-native services — CrowdStrike Falcon Complete and Rapid7 MDR — deliver the deepest integration with their own detection stack but assume you adopt that platform. eSentire is strongest where the estate is Microsoft-centric across Sentinel and Defender.
Two questions separate good outcomes from disappointing ones. First, data ownership: some providers retain your telemetry inside their own platform, which raises switching costs and complicates bringing the function back in-house, so confirm whether logs remain in a SIEM you control. Second, response authority: many SOCaaS contracts detect and recommend but do not contain threats unless active response is explicitly contracted, so clarify what the provider is authorised to do at three in the morning. Outsourcing the SOC does not transfer regulatory accountability, which stays with your organisation.

SOC-as-a-Service is usually priced per endpoint or per user per month, sometimes with a platform or data-ingestion component, and most enterprise contracts are quote-only because pricing depends on telemetry volume, retention and response scope. Mid-market managed offerings commonly fall in the range of a few dollars to the low tens of dollars per user per month, while platform-native enterprise MDR is typically contracted as an annual commitment. Pricing verified June 2026. Enterprise pricing requires a quote, so contact each provider for a scoped figure.
The limitations to plan for are real. Outsourcing the SOC does not transfer accountability — your organisation remains responsible to regulators and customers. Many contracts detect and advise but do not actively contain incidents unless response is explicitly purchased, which can leave a gap during a live attack. And providers that keep telemetry in their own platform increase switching costs and make it harder to repatriate the function later. Read the response runbook and the data-ownership terms as carefully as the detection claims, and validate them in a proof of value.
