Empirical Security builds precision Al tuned to your cybersecurity environment
Empirical builds data-driven models for security teams. We're building the world's first local models for cybersecurity, we maintain the world’s most advanced global models, and we power existing open-source technology — EPSS, used by over 120 vendors today.

CloseEPSS Model
EPSS provides a prediction of the probability of exploitation of a vulnerability. It uses data contributed by participating vendors and is the free and open model used by over 120 vendors to score vulnerabilities. Empirical maintains and trains the model.
Empirical Global Models
Global models combine real-time internet exploitation telemetry with EPSS predictions to provide the most accurate view of exploitation. It monitors activity over 16,000 known exploited in the wild CVEs, and uses that data in the model. This is 12x DHS CISA’s KEV, and far more than any other vendor out there.
Empirical Local Models
Your enterprise has environmental and telemetry data that should be used in decision making. Empirical unlocks the value of these datasets by training a local model, specific to you and only accessible by you, to support your enterprise’s decision making.
We're building the first domain and enterprise specific models in cybersecurity
Enterprises are unique. Security tools aren’t.
Every organization runs its own stack, faces different threats, and operates under different constraints. Yet most security products treat them the same—shipping generic rules and risk scores that ignore local context.
AI needs to be local, not just large.
Modern AI enables us to model security posture, asset value, and attacker behavior with real precision—but only if we adapt to the enterprise’s actual environment. Local models let us reflect your infrastructure, your priorities, and your risk—not someone else’s.
Static logic can’t keep up.
Traditional security tools rely on static playbooks and CVSS scores, producing the same alerts everywhere. That’s why teams drown in backlogs while attackers move faster. Local, adaptive models cut through the noise and surface what really matters—for your environment.
