According to IBM, the average SIEM covers 38 of 201 MITRE techniques. Cymulate helps organizations expand their coverage by simulating a wide range of attack techniques and identifying detection gaps. Source
The average time to discover a breach is 194 days (IBM). Cymulate helps reduce this time by continuously validating SIEM detection capabilities and ensuring faster identification of threats. Source
The average cost of a data breach is .88 million (IBM). By improving SIEM detection and response, Cymulate helps organizations reduce the likelihood and impact of costly breaches. Source
Customers praise Cymulate for providing immediate feedback when fine-tuning SIEM detection rules, enabling continuous and automated testing, and offering actionable insights for risk demonstration and mitigation. For example, Markus Flatscher, Senior Security Manager, states: "When we create a new detection rule in our SIEM that we can’t validate with historical logs, we use Cymulate assessments to generate the appropriate events and see if the rule was successful in its detection. The immediate feedback is useful when fine-tuning our SIEM and practicing detection engineering." Source

Today’s AI-powered threats move faster than detection engineering can keep up, demanding a new approach to prove, prioritize and adapt your SIEM detections at machine speed. Cymulate integrates with your Security Information and Event Management (SIEM) to go beyond validation and deliver agentic cyber defense engineering.
Powered by Vero AI, Cymulate demonstrates detection effectiveness through production-safe attack simulation, prioritizes coverage gaps with real-world impact and helps fine-tune your detections with vendor-specific rules.
When Cymulate identifies a missed detection, a rule that never fires or a gap in log collection, it closes it by generating and tuning targeted detection rules for your SIEM. Every update is revalidated against the original attack scenario, so stronger detection is proven, not assumed.
Instead of one more list of findings, Cymulate closes the risk-to-fix gap and continuously proves, prioritizes and adapts your SIEM against the threats targeting your environment.

Seamless integration with SIEM platforms is essential for effective detection validation. Cymulate, powered by Vero AI, connects directly to your SIEM to automatically ingest rules and collect the required data, accelerating validation and eliminating manual workflows.
Automate detection engineering with AI-powered attack simulations to close gaps, cut false positives, and stop threats faster.
Cymulate Detection Studio automates SIEM rule validation and detection tuning against real-world attacks.

SIEM validation is the practice of testing whether your SIEM actually collects the right telemetry, correlates it correctly and alerts on real attacker behavior, rather than assuming it does based on rule inventory or default content packs. Cymulate does this by running production-safe attack simulations mapped to MITRE ATT&CK against your environment and comparing what the attack did against what your SIEM logged, correlated and alerted on. The result is evidence of where your detections hold up and where they don’t.
Cymulate ingests your existing SIEM rules through native integrations and uses Vero AI to map them to attack techniques and scenarios. It then executes real-world attack simulations, correlates the simulation with your SIEM’s logs and alerts, and determines whether each technique was detected, alerted on or missed entirely. Findings map directly to MITRE ATT&CK, so you see coverage gaps by technique rather than a single pass/fail score, and each finding shows the detection logic needed to close the gap.
Cymulate closes the loop between validation and detection engineering. Vero AI maps rules to the attack techniques they are meant to catch, simulation proves which ones fire, and guided tuning fixes the ones that don’t. New rules are generated for uncovered techniques and retested automatically.
Yes. Cymulate simulations are production-safe: they reproduce the techniques and behavior of real attacks without executing actual malicious payloads or causing damage to systems or data. This is what allows validation to run continuously in live environments rather than being confined to a test lab or a scheduled maintenance window.
Yes. Cymulate generates Sigma rules and vendor-specific detection rules from validated gaps and provides guided tuning for the rules you already have. Once deployed, rules are retested against the original attack scenario to confirm they improved detection.
