Managed SIEM Sizing & Storage Calculator | ATA

SIEM EPS & Storage Sizing Calculator 🧮

Estimate your corporate syslog generation footprint, log ingestion rate, and storage limits for SIEM architectural planning.

⚠️ Baseline Metric Disclaimer: This calculator is specifically architected for standard corporate workspaces and local enterprise networks under the ata.co.il service framework. It does not account for high-frequency bulk mail transactional servers, public web hosting farms, or public application APIs which generate disproportionate log telemetry.

🏢 Corporate Scale

Number of Active Corporate Users / Endpoints:

🔥 Perimeter Firewalls

Primary Firewall Infrastructure Vendor:

Select All Required Firewall Log Types (Multiple Selection):

High Severity & IPS Alerts Records drops, configuration modifications, and active IPS block triggers.

VPN & Remote Ingress Access Sessions Captures authentication audits, telemetry handshakes, and remote tunnel sessions.

Full Forensic Session Audit (All Traffic) Logs every connection handshake, web routing string, and bypass rule. High storage overhead.

🛡️ EDR / Endpoint Security

Deployed Enterprise EDR Vendor Platform:

Select EDR Telemetry Scope (Multiple Selection):

Standard Security Incidents Ingests active malware alerts, dynamic heuristic triggers, and remediation logs.

Verbose Behavioral & Process Telemetry Tracks complete raw execution process trees, file hashes, and deep registry shifts.

☁️ Microsoft 365 Ingestion Cloud Channels

Select Active Microsoft 365 Graph Connectors:

Azure AD / Entra ID Sign-In Telemetry Logs authentication attempts, MFA failures, and conditional access tokens.

Unified Audit Logs (SharePoint, Exchange, Teams) Records admin actions, mailbox adjustments, and corporate file downloads.
