Escape IBM QRadar Sunset:
CrowdStrike Falcon Next-Gen SIEM Cutover
Avoid forced vendor transition paths and aggressive 3-year MSSP renewals. Migrea provides an independent, fixed-price 4–6 week engineering cutover from IBM QRadar to CrowdStrike Falcon Next-Gen SIEM with zero EPS throttling penalties and Zero 24/7 Managed SOC Lock-In (Build, Validate, Transfer Keys).
LogScale handles petabyte bursts without event license drop queues.
Sub-90 second host isolation replaces manual QRadar offense triage.
Live dual-run parity verification before turning off QRadar consoles.
You retain 100% tenant ownership, detection IP, and admin keys.
Replacing DSMs, Custom Event Properties & AQL Offenses
QRadar's 15-year-old architecture relies on physical or virtual appliances (Event Collectors 1501, Event Processors 1601, and Magistrate Consoles) chained together with brittle XML Log Source Extensions. Here is how Migrea modernizes every layer.
DSMs & LSX XML to Native Falcon Connectors
In QRadar, supporting non-standard data sources requires writing fragile Log Source Extension (LSX) XML regex files that break whenever log formats change. Migrea replaces these legacy DSMs with native CrowdStrike Falcon Data Connectors and Cribl Stream pipelines that normalize incoming telemetry directly into modern, resilient schemas.
QID Mapping & Building Blocks to CPS / OCSF
QRadar hides real security logic behind proprietary numeric QID maps and cascading "Building Block" rule definitions that become unmaintainable black boxes. Migrea audits your active QIDs and maps them into clear, human-readable CrowdStrike Parsing Standard (CPS) attributes and OCSF event types.
Magistrate Offenses to Streaming CQL & SOAR
QRadar's Custom Rules Engine (CRE) chains events into static "Offenses" through database locking, frequently dropping events when EPS exceeds appliance limits. CrowdStrike LogScale processes streaming logs in RAM at petabyte scale, piping confirmed high-severity incidents immediately into Falcon Fusion SOAR for sub-90s automated containment.
Side-by-Side Logic Translation: QRadar AQL vs. Falcon CQL
Examine how QRadar relational SQL-like table queries transform into high-velocity, in-memory pipeline streaming filters in CrowdStrike Falcon Next-Gen SIEM.
Detection 1: Credential Brute-Force & Password Spray Anomaly
SELECT "userName", "sourceIP",
QIDNAME(qid) as EventName,
COUNT(*) as FailCount,
MIN(starttime) as FirstAttempt,
MAX(starttime) as LastAttempt
FROM events
WHERE (qid = 27750001 OR qid = 27750002)
AND "userName" IS NOT NULL
GROUP BY "userName", "sourceIP"
HAVING FailCount > 10
ORDER BY FailCount DESC
LAST 15 MINUTESQRadar relies on the Ariel database engine with disk cursor locks, creating query queues and slowing down the console when indexing heavy Windows Event 4625 feeds.
#event_simpleName=UserLogonFailed2
| test(UserPrincipalName != "")
| groupBy([UserPrincipalName, cIp], function=[
count(as=FailCount),
min(@timestamp, as=FirstAttempt),
max(@timestamp, as=LastAttempt),
collect([UserAgent, FailureReason])
])
| test(FailCount > 10)
| sort(FailCount, order=desc)Falcon LogScale streams failure events directly through RAM. Automatically correlated with CrowdStrike Falcon Identity Threat Protection to confirm whether the target account has MFA enforced.
Detection 2: Lateral Reconnaissance & Internal Subnet Port Sweep
SELECT "sourceIP",
COUNT(DISTINCT "destinationPort") as DistinctPorts,
COUNT(*) as TotalConnections,
GEO::LOOKUP("sourceIP", 'country_name') as GeoLocation
FROM events
WHERE devicetype = 12
AND "destinationIP" LIKE '10.%'
AND "action" = 'Reject'
GROUP BY "sourceIP"
HAVING DistinctPorts > 40
LAST 10 MINUTESQRadar firewall DSMs require massive disk I/O to compute distinct port counts across millions of dropped packets, frequently breaching appliance EPS thresholds.
#event_simpleName=NetworkConnectIP4
| cidr(RemoteAddressIP4, subnet="10.0.0.0/8")
| test(Action = /reject|drop|blocked/i)
| groupBy([LocalAddressIP4], function=[
count(RemotePort, distinct=true, as=DistinctPorts),
count(as=TotalConnections),
collect(RemotePort, limit=20)
])
| test(DistinctPorts > 40)LogScale aggregates in RAM using high-speed bitset registers. If triggered, Falcon Fusion SOAR instantly triggers a network isolation workflow on the infected source host in < 90 seconds.

Why Not Just Bundle Your Migration Into an MSSP?
With the sunsetting of IBM QRadar SaaS, global MSSPs are aggressively pitching "free" or discounted migrations conditioned upon multi-year Managed SOC contracts. Here is why enterprise CISOs choose Migrea's independent engineering model instead.
You Lose Console Control & Detection IP
- × Black-Box Tenant Architecture: The MSSP deploys their own rules inside their shared portal. You never receive administrative access or master API keys to your SIEM.
- × Hostage Detection Logic: If you cancel or renegotiate the MSSP retainer after 3 years, they revoke all custom correlation rules and playbooks, forcing you to rebuild from scratch.
- × Escalating Annual Overhead: What started as an "inexpensive" migration morphs into $120,000–$300,000/year in rigid Tier 1 ticket-triage fees.
100% In-Tenant Engineering Ownership
- ✓ 100% In Your Falcon Console: We execute all engineering directly within your CrowdStrike tenant under least-privilege credentials. Zero data egress.
- ✓ You Own 100% of the Content: All CQL queries, dashboards, and Falcon Fusion SOAR playbooks belong permanently to your organization.
- ✓ Bilingual Knowledge Transfer: We train your internal team in native English or Spanish with detailed architectural runbooks, then hand over the master keys. Zero ongoing retainer required.
Signed 30-Day Atomic Detection Parity Certificate
We do not decommission your legacy QRadar appliances until your SOC verifies 100% detection parity, zero missed alert criteria, and flawless ingestion hash matching under real peak traffic.
