Istary — We Make Cybersecurity Intelligent with Domain-Specific AI

Fine-tuned models, domain-specific datasets, and cybersecurity products — we build the AI foundation and the products that run on it.

AI is everywhere. Cybersecurity-grade AI is not.

General-purpose AI hallucinate security data, and their built-in safeguards actively refuse to work on cybersecurity subjects. They weren't built for this domain.

The gap between AI hype and cybersecurity reality is where Istary lives.

Built on Forge. Ready to deploy.

Threat Intelligence Platform

The result of our threat intelligence expertise and foundational AI combined. A modern intelligence platform that utilizes the best of both worlds.

AI Investigation Agent
Investigate breach activity through natural language queries. Correlates credential data and produces structured breach insights — via Cursor, Claude Desktop, or MCP clients.
Real-Time Exposure Alerts
Instantly notified when new credentials linked to your assets appear in breaches, malware logs, and phishing kits.
Structured Breach Intelligence
Raw infostealer logs (RedLine, Raccoon, LummaC2, Vidar) parsed and indexed into structured intelligence. 50B+ data points, sub-second queries.
Web, API & AI Agent
Visual search with credential graphs and exportable reports. REST API for integration into your security stack. AI agent for natural language investigation.

Red Team Tools

AI-augmented offensive security tools for red team operations. Automated reconnaissance, attack surface mapping, and adversary simulation — built on the same AI foundation.

“Bringing the same domain-specific AI advantage to offensive security.”

Security AI, built by security people.

Built by cybersecurity experts

Not an AI lab experimenting with security. We come from the trenches.

Trained on real threat data

Actual malware campaigns, dark web markets, infostealer logs, and CTI reports.

Speaks the security language

Natively understands MITRE ATT&CK, IOCs, TTPs, YARA rules.

Battle-tested by our own products

We build the foundational AI and use it to power our own cybersecurity solutions. Every model ships proven.

The cybersecurity industry needs better AI foundations — models that understand threats, tools that integrate into real workflows, datasets that reflect the adversary landscape. Istary builds that foundation.
