The Company
Behind the Shield

Founded in 2019, ShieldGrid AI has grown from a London-based research lab to a globally trusted AI cybersecurity platform — protecting over 500 enterprises across 60 countries.

AI Incident Response Center
Our Story

Born from the Frontlines of Cyber Warfare

ShieldGrid AI was founded by a team of ex-GCHQ analysts, CERN network security researchers, and Silicon Valley engineers who shared a single conviction: that traditional cybersecurity was fundamentally broken. Rule-based systems couldn't keep pace with AI-augmented adversaries.

We built NeuroShield™ from scratch — a deep learning engine that doesn't just react to known threats, but predicts and prevents unknown ones. Today, our platform protects banks, hospitals, government agencies, and Fortune 500 companies across 60+ countries.

Our Principles

What We Stand For

Our culture is defined by three unwavering commitments that guide every decision — from how we build our product to how we serve our clients.

01

Security Without Compromise

We never trade security for convenience. Every product decision is made with the assumption that adversaries are watching — because they are.

02

Radical Transparency

We believe clients deserve to understand exactly how our AI makes decisions. Our models are explainable, auditable, and never a black box.

03

Adversarial Thinking

We red-team everything we build. Our internal adversarial AI continuously tests our own defences — making us our own toughest critic.

Case Studies

Real Threats. Real Results.

How ShieldGrid AI has defended some of the world's most targeted organisations from sophisticated cyber attacks.

Financial ServicesIncident Response

Tier-1 Bank Stops Nation-State APT in 2.8 Seconds

A major European bank faced a sophisticated Lazarus Group intrusion targeting core banking APIs. ShieldGrid's NeuroShield™ engine detected the multi-stage attack at the reconnaissance phase and autonomously contained all 47 compromised endpoints before any data exfiltration.

NHS Trust Defeats Ransomware Before Encryption Begins

LockBit 4.2 ransomware entered an NHS Trust network through a phishing email. ShieldGrid detected the polymorphic dropper at execution via behavioural AI, triggered isolation of the infected workstation, and prevented lateral movement — all before a single file was encrypted.

Energy Provider Survives 3.4 Tbps DDoS Attack

A coordinated DDoS attack targeting a major UK energy provider's operational control systems reached 3.4 Tbps — one of the largest attacks ever recorded in Europe. ShieldGrid's network layer detection and mitigation absorbed the attack with zero operational downtime.
