The Best SOC as a Service Providers UK
The best SOC as a service providers for UK businesses in 2026 price monitoring on a transparent per-endpoint or per-user subscription rather than a bespoke scoped contract, scale elastically as your estate grows or shrinks, and onboard in weeks rather than months. This guide compares 7 providers serving UK buyers on that commercial model: Precursor Security, Bridewell, NCC Group, Redscan (Kroll), e2e-assure, Arctic Wolf, and Secureworks.
Seven SOC as a service providers serving UK businesses, compared on the commercial model that sets SOCaaS apart from a traditional managed SOC: transparent per-endpoint or per-user pricing, elastic scaling as your estate grows or shrinks, and how fast you can actually get monitored.
SOC as a service is a commercial model, not just a capability.
"SOC as a service" and "managed SOC" get used interchangeably, but they are not the same purchase. A traditional managed SOC is usually a bespoke, scoped, multi-year contract negotiated after a discovery cycle. SOCaaS is meant to be the subscription version: a per-endpoint or per-user rate you can see before you talk to sales, elastic scaling as headcount and endpoints change, and onboarding measured in days, not months. This guide ranks providers on how well they actually deliver that commercial model, not just on SOC capability.
If you want the broader capability comparison, floor photos, and 24/7 staffing question, see our best managed SOC providers UK guide. We are Precursor Security, and we have ranked ourselves first here too; the criteria are published in full below so you can weigh it yourself, and any CREST claim can be checked in the independent CREST member directory.

Verified against each provider's public website and public corporate records, September 2026. "No" under pricing means a per-endpoint or per-user rate was not published at the time of writing, not that a provider is more expensive. Ownership reflects public records: Redscan is part of Kroll; Secureworks is part of Sophos.
The 7 best SOC as a service
providers for UK buyers
1. Precursor Security
Precursor sells its SOC as a genuine subscription: per-endpoint pricing on a published sliding scale, with a floor rate as low as £4 per endpoint per month reached around 2,000 users and endpoints. The SOC itself is physical and UK-based, in Newcastle, with analysts in Newcastle and Leeds, CREST-accredited, and fully UK-staffed with no offshoring. Deployment runs API-first against your own Microsoft Sentinel or Elastic Cloud tenant, live in 14 days from contract signature. Critical alerts get human analyst investigation within 10 minutes, 24/7/365, with active containment through your EDR and identity provider APIs and a 5-day DFIR retainer included as standard rather than sold as a bolt-on. Penetration test findings feed directly into detection rules through the closed-loop model.
Trade-off: A UK mid-market specialist rather than a global enterprise brand, and the per-endpoint model assumes a cloud-native or SaaS-heavy estate rather than a heavily on-premise one.
2. Bridewell
Bridewell is a UK-headquartered consultancy well known for its 24/7 SOC work with critical national infrastructure, energy, transport, and government, alongside a broad advisory and testing practice. Engagements are scoped and contracted individually rather than sold as a published, self-service subscription, which suits sector depth over commercial elasticity.
Trade-off: A larger consultancy engagement model built around scoped contracts, not a per-endpoint subscription. Pricing is on application.
3. NCC Group
NCC Group is one of the largest UK-headquartered security firms, headquartered in Manchester, running managed detection and SOC operations alongside a deep testing and research practice and global delivery capacity. For a large or multinational estate, few UK firms match its scale, though engagements are structured as enterprise contracts rather than a published subscription tier.
Trade-off: Built for enterprise procurement cycles; the contracting model is scoped, not elastic per-endpoint billing. Pricing is on application.
4. Redscan (Kroll)
Redscan, now part of Kroll, runs SOC and managed detection operations with the backing of Kroll’s global incident response and forensics business. For organisations that want monitoring, an IR retainer, and forensics under one roof at enterprise scale, the Kroll relationship is the appeal, delivered through negotiated contracts rather than an off-the-shelf subscription tier.
Trade-off: Kroll is US-headquartered and the engagement model leans enterprise scoped contract, not self-service subscription. Pricing is on application.
5. e2e-assure
e2e-assure is a UK-headquartered managed SOC specialist that runs its own detection platform and emphasises UK-based delivery and threat hunting. For a mid-market buyer who wants a focused, independent UK SOC relationship, it is a credible option, though pricing is scoped per engagement rather than published as a per-endpoint rate.
Trade-off: A SOC specialist rather than a combined offensive-and-defensive provider. Pricing is on application.
6. Arctic Wolf
Arctic Wolf is a US-headquartered provider offering a large-scale security operations platform with a concierge model that pairs each customer with a named team. Its scale, integrations, and 24/7 operations suit organisations comfortable with a global provider, contracted individually rather than priced on a published per-endpoint scale.
Trade-off: Headquartered and primarily operated from the US, which matters for UK data-residency and support-hours preferences. Pricing is on application.
7. Secureworks
Secureworks is a long-established US-headquartered provider built around its Taegis platform, and is now part of Sophos following its 2025 acquisition. For organisations wanting a mature global platform with a large threat-research pedigree, it remains a serious option, sold through negotiated licensing rather than a published per-endpoint subscription rate.
Trade-off: US-headquartered and mid-integration into the Sophos portfolio; UK data residency and platform direction are worth confirming. Pricing is on application.
How we ranked them
Six criteria specific to the as-a-service commercial model, each something a buyer should care about and can verify without taking anyone's word for it.
Whether you can see a published rate before a sales cycle, ideally per endpoint or per user, so cost is something you can model as your estate grows rather than something a discovery call reveals.
Whether the subscription genuinely flexes as headcount, endpoints, and cloud accounts change, or whether "as a service" branding sits on top of a fixed annual contract that cannot shrink mid-term.
Whether you go live in days or weeks through API-first integration, or whether onboarding is a bespoke project measured in months. A subscription that takes a quarter to deploy is not really a subscription.
Whether the advertised rate already includes 24/7 triage, threat hunting, and incident response, or whether those arrive later as separately priced add-ons once you are locked in.
Where the SOC and analysts physically sit, and where your telemetry is processed. UK buyers with GDPR, NIS2, or public-sector data-handling requirements often need a UK-resident SOC regardless of how the pricing is structured.
Whether the provider also runs penetration testing that feeds detection rules, so the subscription you are buying has been tested against real attack paths. This is the closed-loop model.
Red flags when choosing
a SOCaaS provider
Whichever provider you choose, including us, walk away if you see these.
"As a service" branding on a rigid annual contract
Ask directly whether the endpoint count can flex mid-term, up or down, without a contract renegotiation. If the answer is a fixed annual commitment with an early-termination penalty, it is a traditional managed SOC wearing SOCaaS marketing.
A per-endpoint teaser price that excludes the real cost
The headline rate should already include triage, hunting, and response. If threat hunting, incident response, or premium integrations are quoted separately once you are onboarded, the real monthly cost is higher than the number on the page.
Alert forwarding with no humans behind it
A cloud dashboard that emails you alerts overnight is monitoring software, not a staffed SOC subscription. Ask what a human analyst does when a critical alert fires at 3am, and how quickly, in writing.
Incident response excluded from the subscription
If IR is sold as a separate retainer rather than included for Critical and High severities, you are paying a subscription price for a fraction of the service, and discovering the gap during your first real incident is the worst time to find out.
An offshore floor behind a UK-branded platform
A UK sign-up flow and a UK phone number are not the same as a UK SOC. Ask where the analysts triaging your alerts physically sit, and ask for evidence, not a claim.
Rip-and-replace onboarding disguised as "fast setup"
True API-first SOCaaS connects to the SIEM and tools you already run. If onboarding actually means migrating off your existing platform before monitoring starts, the deployment timeline and the disruption cost are both worse than advertised.
What SOC as a service costs in 2026
Across the UK market, monitoring priced through a scoped contract typically runs £900 to £12,000 or more a month depending on tier and estate size. A per-endpoint subscription reframes the same spend as a rate you can model: Precursor's SOCaaS starts as low as £4 per endpoint per month, reached around 2,000 users and endpoints, with a fixed monthly quote in writing after a 30-minute scoping call rather than a procurement cycle.

Choosing SOC as a service
The questions buyers ask most when comparing UK subscription-based SOC providers.
SOC as a service (SOCaaS) is a subscription-based, cloud-delivered security operations capability. A third-party SOC monitors your environment 24/7 through a cloud-native platform, priced per endpoint or per user rather than as a bespoke scoped contract, with dashboard access from day one and integration into the tools you already use. It is the SaaS delivery model for outsourced SOC: the same 24/7 monitoring, triage, and response capability as a traditional managed SOC, sold as an elastic subscription instead of a fixed-scope engagement.
Precursor prices SOC as a service per endpoint per month on a sliding scale, with a floor rate as low as £4 per endpoint per month reached around 2,000 users and endpoints. Across the wider UK market, managed SOC and SOCaaS pricing typically runs from around £900 per month for a small organisation, £3,000 to £4,000 per month for a mid-sized environment with EDR and cloud logs, up to £8,000 to £12,000 or more per month for large multi-cloud estates. Providers that publish a per-endpoint rate let you model cost as you scale; providers that quote on application usually cannot until after a discovery call.
SOC as a service is a delivery model: cloud-native platform, subscription pricing, self-service onboarding, and elastic per-endpoint or per-user billing. Managed SOC is the broader category, and includes on-premise, hybrid, and bespoke engagements priced through a scoped, often multi-year contract rather than a published rate card. MDR is narrower again: the detection-and-response service, often wrapped around your existing EDR and SIEM, that most SOCaaS and managed SOC providers deliver from the same analyst team. In practice, a provider offering true SOCaaS should be able to quote a per-endpoint price on a scoping call; a provider offering only managed SOC usually needs a full discovery and procurement cycle first.
A genuine SOCaaS subscription should include 24/7 human triage (not just alert forwarding), active containment through your EDR and identity provider APIs rather than advisory-only alerting, incident response for Critical and High severities as standard rather than a separately priced add-on, a customer portal with full visibility into alerts and actions, and a UK-based analyst team if data residency or GDPR obligations require it. Check whether the advertised per-endpoint rate already includes threat hunting and incident response, or whether those are quoted separately once you are onboarded: that gap is where "as a service" pricing quietly turns into a traditional scoped contract.
UK buyers typically shortlist a mix of subscription-first UK specialists and larger global or enterprise-contract providers. This guide compares seven that serve the UK market: Precursor Security, Bridewell, NCC Group, Redscan (Kroll), e2e-assure, Arctic Wolf, and Secureworks. The right choice depends on whether pricing is published per endpoint or quoted on application, how fast the provider can onboard your environment, whether incident response and threat hunting are included in the subscription or sold as add-ons, where the SOC and its analysts physically sit, and whether the provider also runs offensive testing that feeds detection.
