SIEM & SOC Calculators
30 free siem & soc calculators in Cyber Security.
Alert False Positive Rate Calculator
Compute false-positive rate, false discovery rate and precision from triage outcomes, then price the wasted analyst time.
Alert Fatigue Calculator
Quantify analyst alert fatigue from queue depth, false-positive rate and shift utilisation, and estimate alerts left untouched.
Alert Volume Calculator
Project daily SOC alert volume from event rate and rule fire rate, after deduplication, suppression and correlation.
Analyst Capacity Calculator
Work out how many alerts one analyst and one shift can genuinely handle from shift hours, utilisation and handling time.
Breach Cost Calculator
Estimate data breach cost per record with lifecycle and control adjustments, following the published cost-of-a-breach structure.
Case Load Calculator
Compare incoming SOC case volume with investigative capacity, and see how fast the backlog grows or clears.
Chain of Custody Calculator
Score the completeness of an evidence custody record — documentation, signatures, hash verification and unexplained gaps.
Detection Rule Coverage Calculator
Score how much of your detection content is actually enabled, fed with telemetry, tuned and tested — not just written.
Evidence Integrity Calculator
Time a SHA-256 verification pass over an evidence set and check the hash algorithm still offers real collision resistance.
Forensic Storage Calculator
Size evidence storage for disk images, memory captures and triage packages, with working copies and retention costs.
Incident Cost Calculator
Total the cost of one security incident: response labour, downtime, third-party support, remediation and overtime.
Incident Response Time Calculator
Model time-to-respond from paging, acknowledgement and escalation hops, and test it against your severity SLA.
IOA Detection Calculator
Estimate the chance of catching an attack chain from behavioural detections, using per-step probability across the chain.
IOC Match Rate Calculator
Measure how much of your threat-intel indicator set ever fires, how precise the matches are, and how much feed decay costs.
MITRE ATT&CK Coverage Calculator
Measure ATT&CK Enterprise coverage across tactics, techniques and sub-techniques, weighted by detection confidence.
MTTD Calculator
Break mean time to detect into dwell, telemetry lag, rule interval, queue delay and analyst confirmation, and find the bottleneck.
Playbook Efficiency Calculator
Compare manual and automated playbook execution, allowing for failures that fall back to manual, and find the break-even run count.
Security MTTR Calculator
Compute security mean time to respond across detect, triage, contain, eradicate and recover phases, with automation savings.
SIEM EPS Calculator
Convert events per day into average, peak and licensable EPS, with headroom and a twelve-month growth projection.
SIEM Log Ingestion Calculator
Turn an EPS figure and a source mix into GB per day, wire bandwidth and annual raw volume using real average event sizes.
SIEM Log Retention Calculator
Work out how many days of logs a given storage budget actually buys, and whether it clears your compliance retention floor.
SIEM Storage Requirement Calculator
Size hot, warm and cold SIEM tiers from EPS, event size and retention, then price the whole estate per month.
Sigma Rule Coverage Calculator
Track a Sigma rule set from applicable to converted to deployed, and find where field mapping loses your detections.
SOAR Automation Coverage Calculator
Measure how much of the triage workflow SOAR really automates, the hours it returns and the payback on the platform.
SOC Health Score Calculator
Roll MTTD, MTTR, false-positive rate, ATT&CK coverage, staffing and automation into one weighted SOC health score.
SOC Maturity Calculator
Score SOC maturity across business alignment, people, process, technology and services on a five-level capability scale.
SOC Staffing Calculator
Size a SOC rota in FTE, including the 4.2–5 FTE per seat that genuine 24×7 coverage requires once shrinkage is funded.
Threat Hunting Coverage Calculator
Score a hunting programme on hypothesis execution, technique and data-source coverage, and conversion of findings into detections.
True Positive Rate Calculator
Derive recall, precision, F1, specificity and balanced accuracy from a detection confusion matrix.
YARA Rule Coverage Calculator
Assess YARA coverage across malware families and check whether your scan throughput can keep up with daily file volume.
