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.

go AI native in cybersecurity.
or compete against someone who will.

Every security vendor and SOC team is evaluating AI right now. Most will plug in ChatGPT and call it a day. The ones that invest in domain-specific AI will detect faster, respond sooner, and take your contracts while you're still triaging manually.

Manual / Generic AI
  • Hallucinated CVEs — 95% of generated advisories are wrong (SECURE benchmark)
  • ~50% precision on ATT&CK mapping — half your technique labels are incorrect
  • Training cutoff blind spots — zero-day and emerging TTPs invisible to the model
  • 40% of alerts go uninvestigated — generic tools add noise, not clarity
Domain-Specific AI
  • Models validated against real CVE databases and live threat feeds
  • ATT&CK mapping trained on actual detection rules and threat reports
  • Continuous ingestion of live data — no training cutoff blind spots
  • 100% alert coverage — AI handles triage so analysts focus on real threats

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, exploit databases, red team engagement data, and attack surface intelligence.

Speaks the security language

Natively understands MITRE ATT&CK, IOCs, TTPs, YARA rules, CVSS scoring, and offensive security tooling.

Battle-tested by our own products

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

Built on Forge. Ready to deploy.

Live

Red Team Tools

AI-augmented offensive security tools. Reconnaissance, attack surface mapping, and adversary simulation — built on the same AI foundation.

Your competitors are already building with domain-specific AI.

The question isn't whether to adopt cybersecurity AI. It's whether you'll build it — or buy it from someone who did.
