Embedded & Critical Systems Security
Security for systems where failure is not an option — defense, aerospace, industrial control and critical infrastructure — engineered from the silicon up.
Explore Embedded Security →Frontier Security Experts
The frontier doesn't fail gracefully.
6QURE secures AI systems, drives post-quantum migration and engineers trust into technologies where failure is not an option.
The Compute Shift
The compute shift is already underway.
Two shifts are arriving together — systems that now act on their own, and cryptography that has to be rebuilt. Each changes the threat model; together they redraw it.
AI is gaining agency.
Models no longer just generate. They plan, call tools, access data, execute workflows and make decisions.
Cryptography is entering transition.
Post-quantum migration is not an algorithm swap. It is a dependency, architecture and lifecycle problem.

Expertise
Securing systems where failure is not an option.
Critical embedded systems, AI, and post-quantum cryptography — three frontiers where the failure modes are new and the margin for error is thin, and where security has to be engineered from the silicon up.
AI & Agentic Security
Secure models, agents, infrastructure and the actions connecting AI to the enterprise.

Turn cryptographic uncertainty into an engineered transition path.
Explore Post-Quantum →Trust Stack
Trust is a system property.
Security fails at the transitions between layers. 6QURE works across them.

Missions
What needs to change?
Engagements begin with a pressure, not a checklist. Find the one closest to yours.
Your AI is moving to production
Architecture · Threat modelling · Runtime controls · Evaluation
Secure the deployment →Your agents can act
Identity · Tool access · Memory · Permissions · Runtime control
Control the agentic layer →You don't know where your cryptography lives
Discovery · Inventory · CBOM · Dependencies
Build crypto visibility →You need a post-quantum migration path
Prioritisation · Hybrid architecture · PKI · HSM · KMS · Deployment
Engineer the transition →Your product's trust model must hold
Root of Trust · Secure boot · Provisioning · Attestation · Firmware
Secure the product →You need an independent technical answer
Architecture · Assessment · Assurance · Expert review
Bring in 6QURE →Deliverables
Engineering you can use.
Every engagement resolves into artefacts your team owns and acts on — architecture, assessments, cryptographic inventories and migration plans, not just findings.

BlacQLeague
Six disciplines. One roster.
Six specialised disciplines, drawn on as each mission requires — the working shape of "expertise, not headcount." The depth on your engagement is matched to the problem in front of it.
01
Adversarial ML & AI Research
Specialists who study how models actually fail, not how they're documented to work.
02
Post-Quantum Cryptography
Cryptographers building for the migration every major standards body has already scheduled.
03
Deep Systems Engineering
Engineers with hands-on depth in the classes of systems they're now hired to secure.
04
Offensive & Adversarial Simulation
Red teamers who test agents the way a real adversary would, not the way a checklist would.
05
Cloud-Native & Infrastructure Architecture
Architects who understand the runtime an agent actually lives in, not just the model.
06
AI Governance & Regulatory Engineering
Specialists who translate the EU AI Act and NIST AI RMF into controls that actually ship.
Roster shown by specialization, not by name or headcount — engagement teams are assembled to mission requirements and disclosed under NDA during scoping.
How We Engage
Expertise, not headcount.
We size the team to the problem — a small number of the right specialists, engaged the way the work actually demands.
