SIEM Replacement
Replace your SIEM in 8 weeks, cut costs 60%
Legacy SIEMs charge per GB, require manual triage, and need SOAR bolted on for response. ManySignal replaces all three with a single agentic platform priced per asset, not per log line.

ManySignal vs. legacy SIEM
A direct capability comparison. No marketing language — just what each system actually does.
| Feature | Legacy SIEM (Splunk/QRadar) | ManySignal |
|---|---|---|
| Pricing model | Per GB ingested — grows with your environment | Flat per-asset — predictable as you scale |
| Alert triage | Manual analyst review of raw events | AI triage agent with confidence scores on every alert |
| Behavioral analytics | Add-on module, separate license | Built into every detection, no extra cost |
| Query language | SPL or AQL — steep learning curve | Natural language + SQL-like, AI-assisted |
| Detection authoring | Manual rule writing, brittle over time | AI-assisted rules with automated backtesting |
| Incident response | Manual playbook execution via SOAR integration | Approval-gated automated containment built in |
| Retention | Hot storage expensive; cold storage awkward | 12-month hot + unlimited cold, flat cost |
| Time to first alert | Weeks of parser/connector work | Pre-built connectors, first alerts in <2 hours |
| Audit trail | Log-level, requires manual reconstruction | Case-level with agent reasoning and approvals |
8-week migration timeline
Structured, parallel migration with zero downtime. Your existing SIEM stays online until you're ready to cut over.
Weeks 1–2
Foundation
- Connect top 5 data sources via pre-built connectors
- Validate normalized event schema
- Import existing detection rules (Sigma/YARA-L supported)
- Run parallel ingestion alongside existing SIEM
Weeks 3–4
Detection parity
- Map all active detection rules to ManySignal equivalents
- Enable behavioral baselines for users and devices
- Configure triage confidence thresholds
- First analyst workflow training session
Weeks 5–6
Response integration
- Configure autonomy ladder policies per action class
- Connect ticketing and on-call systems (Jira, PagerDuty, ServiceNow)
- Enable approval-gated containment actions
- Start parallel SOC operations
Weeks 7–8
Cutover
- Validate detection coverage against legacy SIEM findings
- Decommission legacy SIEM data ingestion
- Final analyst certification on new workflow
- Go-live with full ManySignal SOC coverage
SIEM replacement — common questions
How do we migrate our existing Splunk detection rules?
ManySignal accepts Sigma format natively. For SPL-based rules, the migration utility converts the logic to ManySignal's detection DSL. Coverage analysis compares your active rule set against ManySignal's pre-built library — most teams find 70–80% of their active rules already have equivalents.
What happens to historical data during migration?
Historical data stays in your existing SIEM during the migration window. ManySignal begins building behavioral baselines from the point of connection. For environments requiring historical search, a read-only connector can forward queries to the legacy system during the overlap period.
How does per-asset pricing compare to per-GB in practice?
A typical enterprise with 5,000 assets and 500 GB/day of log volume pays $180,000–$220,000 annually with Splunk. The same environment on ManySignal runs $85,000–$110,000 — a 50–60% reduction. The gap widens as log volume grows, since ManySignal pricing doesn't change with ingest volume.
Can we run both systems simultaneously during migration?
Yes. Parallel operation is the standard migration approach. Most customers run 4–6 weeks of parallel ingestion to validate detection parity before decommissioning the legacy SIEM. ManySignal's migration team manages this at no additional cost.
What certifications does ManySignal hold?
ManySignal is SOC 2 Type II certified, ISO 27001 certified, and maintains FedRAMP Moderate authorization. Data residency options cover US, EU, and APAC regions.
How does ManySignal handle compliance reporting that our SIEM currently produces?
ManySignal generates control-effectiveness reports, compliance dashboards, and audit evidence packages that replace SIEM-based compliance reporting. These are produced from live operational data — verdicts, response actions, coverage metrics — rather than from manually maintained report templates.
What is the risk if we detect a gap in coverage during migration?
The migration is staged: ManySignal runs in parallel and all shipped detections start in alert-only mode. A coverage gap analysis compares your active SIEM rules against ManySignal's detection library before you begin. Any gaps are filled before cutover — the legacy SIEM stays active until parity is validated.
Do we lose our SIEM customisations and tuned rules?
Custom rules in Sigma format migrate automatically. SPL or KQL custom rules migrate via the migration utility with analyst review. Business-context suppressions and escalations are recreated in ManySignal's context rule system — often with cleaner logic than the equivalent SIEM workarounds.
How do analysts learn the new platform?
ManySignal's analyst workflow is intentionally simpler than a SIEM dashboard: analysts receive pre-triaged cases rather than raw alert queues. Training covers the case UI, autonomy ladder management, and the detection-as-code workflow. Most analysts are productive within 2–3 days of training.
What is the SLA if something goes wrong with the migration?
A dedicated migration engineer is assigned for the full 8-week migration period. Migration issues are treated as P1 support events with a 4-hour response SLA. If cutover readiness cannot be validated within the agreed timeline, the migration timeline is extended at no additional cost.
