Yes. What you’re describing is typically sold as Managed Detection & Response (MDR) or a co-managed SOC: analysts continuously triage SIEM alerts, tune detections, investigate suspicious activity, and escalate only validated incidents.
A few providers worth evaluating:
Don't just ask "Do you provide 24/7 monitoring?" Ask specifically:
The key distinction is MSSP/SIEM monitoring vs. genuine MDR: if your main problem is alert fatigue, you want a service that actually investigates and suppresses noise, not one that simply watches your SIEM and forwards everything to your team. The UK's NCSC likewise recommends triage feedback, carefully bounded allow-listing, and correlating related alerts as ways to reduce false positives.
If you tell me which SIEM you're using (e.g., Microsoft Sentinel, Splunk, QRadar, Elastic) and roughly how many alerts you receive per day, I can narrow this to providers that integrate with your stack.
Drowning in SIEM alerts is a classic operational bottleneck. To solve this, organizations typically partner with **Managed Detection and Response (MDR)** or **Managed SOC** providers who ingest your SIEM's telemetry (or plug into your existing security stack via APIs) and use human-in-the-loop triage, behavioral…
Drowning in SIEM alerts is a classic operational bottleneck. To solve this, organizations typically partner with Managed Detection and Response (MDR) or Managed SOC providers who ingest your SIEM's telemetry (or plug into your existing security stack via APIs) and use human-in-the-loop triage, behavioral analytics, and AI to suppress the noise.
Top-tier providers offering managed services specifically designed to cut down on false positives and alert fatigue include:

A few established providers to look at:
The important distinction is “we monitor your alerts” vs. “we actually investigate and suppress noise.” Ask each provider:
If your main objective is “we already have a SIEM and need someone to take the alert firehose off our team's hands,” Expel, Arctic Wolf, Rapid7, and Huntress are particularly worth putting into an initial comparison because their published offerings explicitly address alert triage/noise reduction.

A few strong options:
If your main problem is “we have thousands of SIEM alerts and don't know which ones matter,” don't just buy 24/7 monitoring. Ask prospective providers specifically about:
My initial shortlist would be Expel, LevelBlue, Huntress, and Microsoft Defender Experts, with the best choice depending heavily on which SIEM and endpoint tools you already use.
If you tell me which SIEM you have (Splunk, Microsoft Sentinel, QRadar, Elastic, etc.), approximate alert volume, and company size, I can narrow this to 3–5 providers that fit your environment and compare them.

A few strong options:
If alert overload is the immediate problem, I'd put Expel, Arctic Wolf, and eSentire at the top of the shortlist. The key question to ask each vendor isn't “Do you monitor our SIEM?” but:
For your specific problem, I'd favor a provider that can take over detection engineering and SIEM tuning, because otherwise you can end up paying for an outsourced team that simply turns your existing alert flood into a different queue. Expel, for example, explicitly describes its onboarding process as identifying noisy/redundant rules and tuning them over time.
If you tell me which SIEM you use (Splunk, Microsoft Sentinel, QRadar, Elastic, etc.), roughly how many alerts/day, and your company size, I can narrow this to 3–5 providers that are a particularly good fit.

A few strong options:
If your main pain is alert fatigue from an existing SIEM, I'd start with Rapid7, Huntress, Digital Hands, and Critical Start rather than simply buying another security platform. The key question is whether the provider can ingest your existing SIEM alerts/logs and actually tune them, rather than just forwarding another stream of alerts to your team.
When evaluating vendors, ask for these five things:
If you tell me which SIEM you're using (Splunk, Microsoft Sentinel, QRadar, Elastic, CrowdStrike, etc.), your approximate company size, and whether you want fully managed or co-managed SOC, I can narrow this to the 3–5 best-fit providers and compare them on capabilities and likely cost.
