CORE CAPABILITIES

What We Deliver

Active Cyber Defense

Detect, contain, and counter-strike attackers in a single engagement. Kernel-level lockout deployed through exploit chains — measured under 100ms from first threat signal to neutralized attacker in our test range.

Adversary Emulation

Genetic-algorithm attack engines that mutate payloads across generations. The red side breeds what works and drops what fails, so defenders train against a target that evolves between runs, not a static signature list.

AI Threat Hunting

Reinforcement-learning specialists distilled from our own red/blue range — one model per attack family, continuously retrained on every new engagement. Signatures are learned from observation, not hand-written.

Post-Quantum Cryptography

ML-KEM-1024 + AES-256-GCM + ML-DSA-65 for unlock-command custody on our defense platform. Lockouts are sealed with NIST-standard PQC so only the operator who set the trap can release it — built for a future quantum adversary, running on standard hardware today.

Edge-to-Origin Defense

Edge detection paired with origin-side enforcement. Per-source-IP escalation ledgers at the edge, kernel-level counter-strike at the origin, authenticated channel between them. Scales across anycast without giving up local kernel control.

Zero-Day Research

Unicode and filter/parser desync research — novel bypass classes catalogued and published. Every offensive technique we discover ships with a detector so the defensive side of the house closes it on the same commit.

Who We Are

NATIONAL SECURITY INTELLIGENCE

National Security Intelligence is a veteran-owned cybersecurity defense contractor based in San Antonio, Texas. We build active cyber defense systems for government agencies, the Department of Defense, and DARPA-class national security missions.

Founded by a 101st Airborne veteran, NSI specializes in the problems where traditional defenses fail: adversaries that mutate payloads across generations, AI-driven attack detection with sub-100ms response, and post-quantum cryptographic lockout that neutralizes threats before a human can read an alert.

As a small business government contractor, we bring defense-grade cybersecurity to organizations of every size — from federal agencies and defense contractors to small businesses that need enterprise security without enterprise budgets. We ship code, not slideware.
