Managed SIEM Providers: Verified Provider Data
DiscoverMSPs tracks providers offering managed SIEM (Security Information and Event Management) services: outsourced log collection, correlation and threat detection built on a SIEM platform. Filter our verified data by pricing model, company size and location.
What is a managed SIEM provider?
A managed SIEM provider operates and monitors a Security Information and Event Management platform on a client’s behalf, collecting log and event data from across the environment, correlating it to detect threats, and alerting or responding when something looks wrong. Running SIEM in-house requires specialized staff to tune detection rules and manage data volume, which is why many organizations outsource the function entirely to a managed provider.
Managed SIEM pricing splits into three broad tiers: entry-level providers targeting SMBs with compliance-focused monitoring run $3,000-$5,000/month; mid-market providers offering full detection and response with transparent pricing run $5,000-$15,000/month (some publish rates around $11-$15 per endpoint per month); enterprise providers run $15,000-$50,000+/month, often on custom, opaque contracts. Pricing models vary by vendor: per-endpoint ($15-$50/asset/month), per-GB of log data ingested ($0.50-$2.00/GB/day), flat monthly tiers, or a hybrid of both.
Choosing a managed SIEM provider
Pricing transparency varies widely across the market. Microsoft Sentinel is one of the few major platforms that publishes real per-GB pricing; most enterprise providers require a sales call to get a quote. Understand the pricing model, not just the headline number, before comparing.
- Whether pricing is per-endpoint, per-GB, or flat monthly
- Data retention period included at the base price
- Whether detection rule tuning is included or billed separately
- Named response times for different alert severities
- No published pricing model or logic, “contact sales” for everything
- Unclear data ownership if you switch providers
- No SLA on alert response times
- Long lock-in contracts with no trial period
