01
AI Red Team Assessments
Time-boxed adversarial assessment of LLM apps, RAG pipelines, and AI agents — injection, tool misuse, RAG poisoning, jailbreak chains — delivered as a prioritized findings report.
Security Architecture · AI Red Teaming
We break AI systems, so attackers can't.
Grey Ridge Signals Group is a security-architecture and AI red-team firm. We assess and design at the architecture level — red-teaming your AI systems and agents and hardening the cloud they run on — in sharp, time-boxed engagements.
What we do
Engagements
An AI-security spearhead backed by senior cloud-security architecture. Sharp, time-boxed engagements — assessment and design, not months of onsite grunt work.
AI Securitythe spearhead
02
Agentic System Security Review
Architecture-level review of multi-agent systems: delegation-chain integrity, privilege-escalation paths, non-human identity, and trust boundaries — with the design changes that close them.
03
Prompt-Injection Defense Design
We design the layered defenses for your AI's input/output surfaces — semantic detection, output scanning, tool governance, cryptographic prompt attestation — and hand your team the blueprint.

04
Cloud Security Architecture Review
An architect's read on your AWS, GCP, or Azure design — identity, network, and PCI-relevant controls — delivered as a prioritized hardening roadmap. The assessment, not the months of implementation.
05
Security Architecture & Threat Modeling
Design-phase review of new systems and AI features — threat models, trust boundaries, and the controls that matter — so it's built right instead of remediated later.
06
Detection & Automation Strategy
The blueprint for your logging, alerting, and security-automation — what to detect, where to instrument, and what to automate — grounded in running detection across 100+ environments.

Fractional Security Architect & AI-Security Advisory
Senior security architecture on tap — design review, threat modeling, and decision support a few hours a week, across both your AI and your cloud. Judgment when you need it; no SOC to babysit.
Why us
Built from systems we run
Our methods don't come from slideware. They come from autonomous offensive- and agent-security systems we designed, built, and operate — which is exactly where we learned how these systems fail.
Autonomous Offensive Research
Meridian
A containerized pipeline that chains reconnaissance → vulnerability analysis → exploit validation.
Built to understand how automated adversaries prioritize and move at scale. It's why we know where autonomous attack pipelines actually break.
Agent Infrastructure · Audit
Division
A hierarchical multi-agent system with durable episodic memory and a full audit trail of autonomous work.
A coordination layer over four-level memory that checkpoints every task. We understand agent memory, context manipulation, and trust-hierarchy attacks from the inside.
AI Agent Security · Cryptography
Seal
Cryptographic provenance for AI-agent prompts — replacing brittle "injection detection" with signatures that fail closed.
Every prompt carries an Ed25519-signed Verified Prompt Envelope proving who authorized it and that it wasn't tampered with. Injection defense by construction, not by vibes.
Threat Intelligence · Attack Surface
Sentinel
Certificate-Transparency monitoring that surfaces new and anomalous infrastructure from internet-scale CT noise.
Continuously correlates public CT logs against tracked roots and surfaces only the new or anomalous. The engine behind our attack-surface monitoring.
How we work
From scope to roadmap
High-leverage by design — we sell senior judgment and design, delivered in weeks, not months onsite.
01 · Scope
Define the target
A few days to map what's in scope — models, agents, cloud accounts — and agree the rules of engagement in writing before anything is touched.
02 · Assess & design
The focused work
One to three weeks of red-teaming, architecture review, and threat modeling. Every finding ties to a realistic threat, not a checklist.
03 · Roadmap
A decision, not a doorstop
A prioritized findings-and-remediation roadmap your team can act on — the architect's read, handed off clean.
04 · Advisory
On call, optional
Keep us a few hours a week for the next decision — design review and threat modeling as you build. No SOC to babysit.
Sharp, time-boxed engagements — we don't embed onsite for months. Judgment and design, delivered.
The firm
Grey Ridge Signals Group
We're a security-architecture firm with an AI-security spearhead. We work where frontier AI meets production security — red-teaming the models and agents teams are shipping, and architecting the defenses around the cloud they run on.
Our work is led by a senior security and cloud architect with 15+ years in production: security architecture across AWS, GCP, and Azure, PCI-relevant multi-cloud migrations, live-service stabilization for AAA game backends, incident response and EDR across 100+ environments, and identity, access, and PKI for U.S. federal systems under a Confidential clearance. CompTIA Security+ / Network+. Alongside client work, we build the autonomous offensive- and agent-security systems above — and we test AI the same way we build it: with an attacker's assumptions and an engineer's rigor.
