VANTAGEA / ENTERPRISE OFFENSIVE SECURITY
Hold the high ground across your whole estate.
We red-team your AI, agents, cloud and identity on a schedule, test the sandboxes your workloads run in and check every acquisition before you sign.
ENTERPRISE PROGRAMMES
One partner across every layer of the stack
Programmes, not one-off tests
Red team cycles and variant research on a schedule, so testing keeps pace with what you ship. Each cycle starts with fresh reconnaissance.
Prompt to cloud
We follow your models, agents, MCP servers and sandboxes through to the identity, cloud and CI/CD systems they can reach.
Evidence your board can use
Reproducible findings mapped to the OWASP LLM Top 10, OWASP Agentic Top 10 and MITRE ATLAS, with an executive brief and retests that confirm each fix.
UK-incorporated, outside US law
Registered in England and Wales and outside the reach of the US CLOUD Act and FISA. We work with regulated, defence and international teams.
WHAT WE OFFER
Security across every layer of the stack
From a single test before launch to a programme across your whole estate. Every engagement ends with fixes your engineers can ship.
AI & AGENT RED TEAMING
Attack your AI before someone else does.
We attack your models, agents and their tools the way an adversary would, then follow every path to the cloud accounts they can reach.

AI INFRASTRUCTURE & ISOLATION
Prove your containment boundary holds.
We try to break out of the sandboxes, micro-VMs and proxies that keep one customer's AI workload away from another's.

SECURITY ASSESSMENTS
Ship the release, not the vulnerability.
We test your web apps, APIs and cloud with or without source code. We also check that past security fixes actually closed the hole.

M&A SECURITY DUE DILIGENCE
Know what you're buying before you sign.
We show you the target's real security position, including the exposed assets the data room left out, in time for signing.

PUBLIC GOOD
Security for the teams that can least afford a breach.
We test for charities and public-interest teams at a discount or for free. We also report bugs privately to open-source maintainers.
