Top SOC As A Service Providers For 2027

Meta Description: Compare 10 SOC as a service providers for 2027: who runs 24/7 monitoring, SIEM operation, triage and escalation, and which managed SOC fits your team.

A security operations center that actually runs around the clock needs at least eight analysts to cover shifts, holidays and sick days, plus engineers to keep the SIEM tuned and detection rules current. Most mid-market companies cannot hire or keep that team, so alerts pile up overnight and on weekends, which is exactly when attackers prefer to move. SOC as a service solves this by renting the whole function: a provider’s analysts watch your logs and telemetry 24/7, operate or tune the SIEM, triage every alert, and escalate the real incidents with clear next steps.

The labels in this market overlap, so it helps to separate them. SOC as a service (often shortened to SOCaaS) is the outsourced SOC itself: monitoring, SIEM operation, triage and escalation, usually built around a log platform the provider hosts or one you already own. Managed detection and response goes further into hands-on containment, typically through endpoint agents, and you can compare those vendors in our list of top MDR providers. An MSSP is broader again, running firewalls, VPNs and other security devices alongside monitoring, and the larger names are covered in our roundup of managed security service providers. In practice many SOC as a service providers now bundle response, so the useful question is what the SOC does after it spots something, not what the product is called.

Every firm here was checked against its own website for a current, staffed 24/7 SOC offering, its headquarters, the SIEM and log platforms it supports, and any published response times, tiers or pricing. Where a company has been acquired or renamed, the current brand is used. Figures quoted below are the providers’ own published numbers, not independent benchmarks.

Best SOC As A Service Providers For 2027

The list runs from providers that host and operate the full SIEM stack, through specialists that run the SIEM you already pay for, to Microsoft-focused services and channel providers that let an MSP sell a managed SOC under its own brand. Pick from the section that matches how your environment is built today.

1. Proficio — Hosted SIEM SOC Running From San Diego, Barcelona And Singapore

Proficio, founded in 2010 and headquartered in Irvine, California, is about as close to a textbook SOC as a service provider as this market gets. Its ProSOC MDR service is described as a fully managed SOC-as-a-Service running on a SIEM that Proficio hosts, so the customer does not have to buy, size or patch a log platform. A ProSOC Collector virtual machine receives logs from network, endpoint, identity, SaaS and cloud sources, and Proficio says no extra network sensors or agents are required to start.

What stands out is the follow-the-sun model: Proficio operates SOCs in San Diego, Barcelona and Singapore, so analysts on each shift are working daytime hours. Valid threats are passed to the client with summarized remediation guidance and tracked in Proficio’s ServiceNow ticketing. For teams that want the SOC to act rather than just notify, the optional Active Defense Response add-on automates containment of high-priority threats across network, endpoint, identity and cloud. Proficio also runs ProSOC MDR for Microsoft on Sentinel and ProSOC MDR for Splunk for customers who already own one of those platforms.

Proficio fits mid-market and enterprise buyers who want SIEM and analysts in a single contract, especially those with operations in Europe or Asia Pacific. The trade-off is that the published detection and containment figures vary between sections of its own site, so ask for the contractual SLA in writing rather than relying on headline numbers.

2. Deepwatch — SOC Operations Built On Five Named SIEM Platforms And 800+ Telemetry Sources

Deepwatch, headquartered in Palo Alto with offices in Tampa and Bengaluru, is the strongest choice here for companies that have already invested in a SIEM and need people to run it properly. Its managed detection and response service plugs into the customer’s existing SIEM, EDR, cloud, identity and SaaS tools rather than replacing them, and the company publishes dedicated offerings for Google SecOps, Splunk, Microsoft Sentinel, Securonix and CrowdStrike Next Gen SIEM.

Deepwatch says its platform supports more than 800 telemetry sources and uses dynamic risk scoring to cut low and medium severity alert volume, which it puts at a 98% reduction. Around the core SOC it sells managed EDR, managed firewall, vulnerability management, continuous threat exposure management and dark web monitoring, plus an Active Response capability for automated action. The Guardian MDR Platform and NEXA AI are the product names you will see in proposals.

The best fit is a larger organization with a Splunk or Sentinel deployment that is underused or poorly tuned, where the goal is to get value from existing licensing. Deepwatch does not publish tiers or pricing, and the program is scoped per customer, so smaller teams without a SIEM may find a hosted option simpler.

3. Lumifi Cyber — SOC 2 Type II Certified US-Based SOC With Sub-10-Minute Threat Response

Lumifi Cyber is based in Scottsdale, Arizona, and runs its 24/7/365 SOC from the United States, with analysts in Scottsdale. It sells SOC as a service delivered as managed detection and response through ShieldVision, its own SOC automation platform, which works with the tools a customer already has. In 2024 Lumifi acquired Netsurion, a managed XDR provider, adding more than 400 clients and a large MSP customer base; the old Netsurion website now redirects to Lumifi.

Several details are concrete and useful for regulated buyers. Lumifi states its SOC is SOC 2 Type II certified, lists threat response at under 10 minutes, and claims more than 1,000 technology integrations, with partners including Exabeam, Elastic, Microsoft, NetWitness, Palo Alto Networks, Splunk, LogRhythm and Stellar Cyber. Customer data stays on the customer’s own infrastructure, and Lumifi says it will show clients how to disconnect any service, including its own, from day one. It protects more than 500 organizations, and its incident response team says a responder can be on the line in under 10 minutes without an existing contract.

Lumifi suits companies that need a US-only SOC for contractual or data residency reasons and want flexibility over which SIEM sits underneath. The site does not publish escalation tiers or analyst headcount, so cover both in the evaluation.

4. CyberMaxx — Three-Tier MaxxMDR With Containment And Remediation Included In Every Tier

CyberMaxx was founded in 2002 and lists its office in Linthicum Heights, Maryland. It has grown by acquisition: it bought Corvid Cyberdefense, which added managed email security and Elastic SIEM capability, and more recently Avertium, whose website now states it is part of CyberMaxx. That deal brings Avertium’s Microsoft security, professional services and GRC work under the same roof as CyberMaxx’s SOC.

The MaxxMDR service is sold in three tiers. Core covers endpoints or email, Advanced covers both, and Elite adds a managed SIEM, full cloud telemetry across AWS, Azure and GCP, network telemetry, deception technology, CTEM, vulnerability scanning and dark web monitoring. The detail worth noting is what CyberMaxx calls “Big R” response: every tier includes investigation through containment and remediation for monitored assets, with deeper forensics available under a separate statement of work at discounted rates. CyberMaxx also runs an offensive security practice that it says logs over 7,000 hours of penetration testing a year and feeds new detections back into the SOC.

CyberMaxx fits mid-market companies that want one provider to watch, contain and clean up. If your priority is a managed SIEM specifically, note that SIEM is only bundled in the Elite tier.

5. UnderDefense — Fully Or Co-Managed SOC With A 20-Minute Critical Alert SLA And Published Rates

UnderDefense was established in 2017 and has offices in New York, Jacksonville, Krakow and Lviv, with more than 120 certified security engineers across three continents. Its Managed SOC (SOCaaS) service is offered either fully managed or co-managed and runs on top of the customer’s existing tools, with the MAXI platform providing AI-assisted investigation, compliance automation and access to the incident response team.

UnderDefense is unusually open about commercial terms. It states a 20-minute SLA response time for critical alerts, says deployment can be completed in 10 days or fewer, and publishes indicative pricing: SOC packages start at a per-device monthly rate, co-managed SIEM starts at $65 per hour, and SIEM-as-a-Service including the SIEM tool starts at $140 per hour. The SOC package includes 24/7 alert triage, threat hunting, incident response guidance, SIEM tuning and monthly reports with compliance support for frameworks such as SOC 2, ISO 27001, HIPAA and PCI DSS. Co-managed SIEM work covers Elastic, Splunk, QRadar, LogRhythm and Sumo Logic, and the company claims more than 1,000 correlation rules.

It suits smaller and mid-sized teams that want to see pricing before a sales call, and internal security teams that want help with SIEM engineering rather than a full handover. The per-device figures on its SOC page differ between sections, so confirm the exact rate for your device count in a quote.

6. Cyderes — Identity-Centric MDR Delivered From Five SOC 2 Certified Centers

Cyderes is based in the Kansas City area, with corporate offices and a Cyber Defense Center in Overland Park, Kansas. It reports more than 800 dedicated security professionals, over 250 security engineers and five global 24/7 security operations centers, which it describes as SOC 2 certified, with locations flagged in the US, UK, Canada and India.

Its distinguishing feature is how closely the SOC is tied to identity. Cyderes sells identity governance, privileged access management and identity threat detection alongside MDR, and its Meridian platform maps identities, assets, access relationships and exposures so the SOC can prioritize incidents by blast radius rather than raw severity. Agentic AI handles correlation and predefined containment, while human analysts make the material decisions and validate containment. Integrations listed on the site include Splunk on the SIEM side and SailPoint, Okta, CyberArk and Delinea on the identity side.

Cyderes is a strong fit for large enterprises where compromised credentials and over-privileged accounts are the main concern, and where one partner for both IAM and the SOC is attractive. It does not publish response times or SLAs on its MDR page, so request them early.

7. BlueVoyant — Three-Time Microsoft US Security Partner Of The Year Running In-Region SOCs

BlueVoyant, which lists its office on East 45th Street in New York, provides 24×7 in-region SOC monitoring across Europe and the US and reports more than 1,000 customers in 45 countries. Its MDR service is designed to get more out of the EDR, SIEM and cloud security tools a customer already owns, with a dedicated MDR for Microsoft module built around Microsoft Sentinel and Defender XDR.

The Microsoft depth is the main reason to shortlist it. BlueVoyant describes itself as a three-time Microsoft US Security Partner of the Year and says it has been recognized by Microsoft ten times, including as Worldwide Security Partner of the Year and Security MSSP of the Year. Its MDR page cites a team of more than 50 certified Microsoft delivery and SOC engineers, unlimited remote incident response lifecycle support, and a separate continuous optimization service for Sentinel and Defender deployments. Beyond the SOC, BlueVoyant sells third-party risk management and digital risk protection, which covers impersonation and fraud takedowns.

BlueVoyant fits organizations running Sentinel that also want visibility into supplier risk from the same provider. Its site does not publish SLAs or escalation timelines, and buyers on Splunk or Google SecOps should confirm platform coverage directly.

8. Ontinue — Microsoft-Only MXDR With Follow-The-Sun Cyber Defense Centers

Ontinue runs its ION MXDR service entirely on the Microsoft security stack. It has a North American headquarters in Redwood City, California, and a European headquarters in Zurich, with SOC locations listed in Redwood City, Zurich, London and Noida and further offices in Dusseldorf, Vienna and Toronto. Its Cyber Defense Center works a follow-the-sun model, with Cyber Defenders monitoring 24/7 and Cyber Advisors acting as technical account managers.

The narrow focus is the point. Ontinue is built for Defender and Sentinel customers and says it resolves 99.5% of alerts without the customer having to take action. Its ION IQ AI learns the customer’s environment and the behavior of both teams, and a Sentinel cost optimization offering targets one of the biggest complaints about Microsoft’s SIEM, data ingestion spend. Add-on services cover vulnerability mitigation, IoT and OT security through Defender for IoT, and enhanced phishing protection. Ontinue holds Microsoft specializations in Threat Protection and Cloud Security and is a member of the Microsoft Intelligent Security Association.

Ontinue is a natural pick for companies already licensed for Microsoft E5 or Sentinel that want a managed SOC without adding more tools. It is a poor fit for mixed environments built on other EDR or SIEM vendors.

9. Field Effect — 24×7 SOC Staffed Almost Exclusively By Five Eyes Intelligence Veterans

Field Effect is headquartered in Ottawa, Canada, with a US office in Lake Mary, Florida, and support numbers in the UK and Australia. Its Field Effect MDR service includes a 24×7 SOC that it says is staffed almost exclusively by veterans of Five Eyes intelligence agencies, working a follow-the-sun schedule so an analyst is always available and customers can reach the analysts monitoring their environment directly.

Field Effect states that 93% of alerts are handled instantly through automation, with the remainder investigated by analysts at a median of 2.6 minutes per investigation. The service comes in three packages: MDR Endpoint for endpoint-focused environments, MDR Core which adds cloud services, and MDR Complete which adds network and AI coverage, extended reporting for insurance and regulatory needs, and an option to extend log retention from 90 days to seven years. A dedicated MSP partner program lets managed service providers resell the service to their own clients, and Field Effect also offers incident response, IR planning and cybersecurity assessments.

It fits small and mid-sized businesses that want a single, packaged service rather than a SIEM project, and MSPs looking for a SOC they can put in front of clients. Pricing is by request only.

10. Cyflare — White-Label SOC For MSPs With 400+ Integrations And A CMMC Level 2 Certification

Cyflare, based in West Seneca, New York, builds its business around the channel. Its pitch to MSPs and resellers is to run the SOC without owning one: Cyflare’s analysts provide 24/7 monitoring, triage, investigation, escalation and response behind the partner’s brand, and every case is documented for the partner’s compliance and audit reporting. The Cyflare ONE platform ties together security data, SOC workflows, automation and reporting across all of a partner’s customer environments.

The numbers it publishes are specific. Cyflare cites more than 400 tool integrations, over 670 active playbooks, more than 1,500 partner-led accounts, an 8.3-minute mean time to respond on critical cases and a false-positive rate under 1%. It is CMMC Level 2 certified, offers a $500K service warranty, and includes a $0 breach response retainer with legal support through The Beckage Firm. The partner program is designed around margins of 40% or more, standardized onboarding and co-selling support, and partners can add managed EDR, XDR, email security, ITDR, vulnerability scanning and CMMC support to their catalog.

Cyflare is the clearest choice for MSPs that want to sell a managed SOC under their own name. End customers buying directly will find most of its material written for partners, and it does not publish contractual SLAs.

How To Choose A SOC As A Service Provider

Most SOC as a service contracts run for one to three years, and switching mid-term means re-onboarding logs, rewriting runbooks and retraining your team. These five questions will separate a provider that fits from one that only demos well.

Who Owns And Operates The SIEM?

This is the first fork in the decision. Some providers host the SIEM for you and include it in the fee, which is simpler and avoids a separate license, but your detection content and historical logs sit in their platform. Others run your existing Splunk, Sentinel, Google SecOps or Elastic deployment, which keeps your data and licensing in your hands but leaves you paying ingestion costs directly. Ask who owns the detection rules if you leave, how many days of searchable log retention are included, what it costs to extend retention for audits, and whether new log sources are added at no charge or priced per source.

What Happens After An Alert Is Confirmed?

A managed SOC that only sends an email at 3 a.m. still leaves your team to do the hard work. Ask for the exact escalation path: who gets called, in what order, how fast, and what the analyst is authorized to do without asking. Some providers isolate hosts, disable accounts and block IPs on their own; others recommend actions and wait. Neither is wrong, but you need to pre-approve the actions you are comfortable with and see them written into the runbook. Also confirm whether full incident response and forensics are included or billed separately once an incident goes beyond containment.

Are The Response Times Contractual?

Marketing pages are full of mean time to detect and mean time to respond figures, but averages hide the slow cases and are rarely what you can enforce. Ask for an SLA that defines when the clock starts, what counts as notification, the target for critical, high and medium alerts, and whether service credits apply when the target is missed. Then ask for last quarter’s actual performance against that SLA for customers of your size. A provider confident in its 24/7 SOC will share real numbers, not just a best case.

Does The Provider Cover Your Actual Stack And Compliance Needs?

List every log source you care about, including identity providers, cloud accounts, SaaS apps, firewalls and any OT equipment, and ask the provider to confirm each one is a supported, parsed integration rather than raw log ingestion. Microsoft-only services can be excellent for E5 shops and useless for mixed environments. If you face audits, check which reports are produced automatically and whether the provider holds its own SOC 2 Type II report. Defense contractors should also confirm how the SOC supports their CMMC compliance checklist, including where data is stored and who can access it.

How Is SOC As A Service Priced?

Pricing models include per device or endpoint, per user, per gigabyte of ingested data, and flat tiers. Per-device pricing is easy to forecast but can penalize server-heavy environments; data-volume pricing can spike when you add a noisy log source. Ask for a quote at your current size and at 30% growth, and check what is excluded: SIEM licensing, retention beyond the default, after-hours incident response, onboarding fees and quarterly reviews are common extras. Compare the total against the true cost of building an in-house SOC instead of an outsourced SOC, which means at least eight analysts for real 24/7 coverage plus tooling and training.

Conclusion

If you want SIEM and analysts in one contract, Proficio’s hosted ProSOC is the most complete package, while Deepwatch is the stronger choice when you already own a major SIEM and need it run well. Lumifi Cyber suits buyers who need a US-based SOC with data kept on their own infrastructure, CyberMaxx bundles containment and remediation into every tier, and UnderDefense gives smaller teams published pricing and a co-managed SIEM option. Cyderes leads on identity, while BlueVoyant and Ontinue are the specialists for Microsoft Sentinel and Defender environments.

For smaller businesses and the MSPs that support them, Field Effect offers a packaged MDR with its own 24×7 SOC, and Cyflare is built for partners that want a white-label managed SOC. Whichever SOCaaS provider you shortlist, pair the service with the basics in our small business cybersecurity checklist, because even the best SOC can only escalate what your controls let it see.
