The Data You Don't Keep Is the Data You Can't Investigate
The Logs You Throw Away Today Could Be the Evidence You Need Tomorrow.
August 25, 2026 | 11 A.M. PT | 30 Minute Webinar
Security logs are receipts.
Legacy SIEM’s pricing models make them almost impossible to keep, but when an incident happens, the question isn't whether the logs are expensive. It's whether they’re available.
For years, security teams have been making seemingly rational decisions to control SIEM costs: sample NetFlow, shorten DNS retention, filter endpoint telemetry, drop domain controller events, and trim cloud and identity data at renewal.
The problem? Every one of those decisions creates a blind spot.
Join us for a look at the security data organizations routinely cut and the detections those decisions quietly make impossible.
What We'll Cover
In this webinar, we'll examine what happens when security teams have to choose between data visibility and data cost, including:
- Sampled NetFlow: What you lose when you can't see complete network behavior
- Short-retention DNS: How limited history undermines DGA detection and long-term threat hunting
- Filtered firewall data: Why dropping accepted traffic can eliminate critical evidence of allowed-egress anomalies
- Reduced endpoint telemetry: What happens when process-level visibility gets replaced by alerts alone
- Missing domain controller events: How incomplete Windows authentication data limits your ability to investigate Kerberos abuse
We'll connect everyday decisions to the MITRE ATT&CK techniques and detection capabilities they can prevent you from investigating.
