Built for defence
Basalt's Portsmouth practice has been working defence threat profiles long enough to know which controls actually move the dial — and which line items quietly waste budget. We bring that pattern recognition in week one.
Portsmouth, United Kingdom
AI Red Teaming in Portsmouth.
Adversarial testing for LLMs and AI systems delivered for defence teams in Portsmouth, United Kingdom. Adversarial testing for production LLM and AI systems — prompt injection, jailbreaks, training-data leakage, agentic tool abuse and model manipulation tested against your real deployments.
Over 200 distinct jailbreak techniques in our active library — across Basalt operations in the past 12 months.
THREAT VECTOR
Threats facing Portsmouth defence.
The defence, maritime concentration around Portsmouth sees ITAR-aware supply chain risk, classified-network adjacency and insider-threat detection. Our ai red teaming work in South East is scoped against this real threat profile, not a generic checklist.
Common pains
- LLM features shipped without an attacker’s perspective
- No process for testing prompt injection or jailbreaks
- Agents wired to tools and data with no abuse modelling
ENGAGEMENT
How we engage.
- Adversarial test suite covering OWASP LLM Top 10
- Prompt injection and jailbreak findings with reproductions
- Tool-use and agent abuse path analysis
- Hardening recommendations and CI guardrails
Reporting
Every finding ships with a control reference against NCSC Cyber Assessment Framework and UK GDPR, with NCSC UK guidance cited where it changes the remediation priority. Board reporting follows the FCA SYSC operational resilience expectation set.
LOCAL CONTEXT
Local context.
Basalt delivers ai red teaming to organisations across Portsmouth and the wider South East region (population ~210k). The defence, maritime sectors that anchor the region face a distinct threat profile — ITAR-aware supply chain risk, classified-network adjacency and insider-threat detection — and our engagements are scoped to that, not a generic playbook. Reporting maps cleanly to the NCSC Cyber Assessment Framework and UK GDPR that British boards already use, with regulator context (NCSC UK) called out where it changes a remediation priority.
RATIONALE
Why Basalt for ai red teaming in Portsmouth.
Reporting that lands
Findings ship with control references against NCSC Cyber Assessment Framework and UK GDPR and remediation guidance written for the team that has to action it. Your board, your auditor, and your on-call engineer all get something they can use.
No vendor bias
Basalt doesn't resell tooling. British defence clients get an independent read on what's working, what isn't, and what's costing more than it should — not a thinly-veiled sales pipeline.
2026 THREAT LANDSCAPE
What we test for.
- Agentic AI tool-abuse and indirect prompt injection at scale
- MCP server and AI-tool supply chain compromise
- Post-quantum cryptographic readiness (NIST PQC migration)
- Identity-first attack chains across federated SaaS
- Open-source software supply chain (post-xz, post-tj-actions)
Cyber security in United Kingdom can't be done with last year's threat models. The Basalt practice runs against current attacker tradecraft — agentic AI abuse, MCP and AI-tool supply chain, post-quantum readiness — alongside the legacy infrastructure work that still keeps most organisations awake at night.
FAQ
Frequently asked questions.
How fast can Basalt start a ai red teaming engagement in Portsmouth?
Most Portsmouth engagements scope inside one week and start within two. Retainer clients can trigger work the same day. We do not pipeline British clients through junior teams — a senior consultant scopes and runs the work end-to-end.
Do you do ai red teaming on-site in Portsmouth or remote?
Both. Sensitive work — classified-adjacent environments, live incident response, OT walkthroughs — gets on-site time in Portsmouth and the wider South East region. Routine assessments and detection engineering run remote with a tight feedback loop.
How does Basalt map findings to British regulators?
Every finding ships with a control reference against the NCSC Cyber Assessment Framework and UK GDPR so your compliance team is not re-mapping our report. Where NCSC UK guidance exists for the specific finding, we cite it inline. Board-level reporting follows the FCA SYSC operational resilience expectation set.
What makes ai red teaming in Portsmouth different from a generic engagement?
The defence sector concentration in Portsmouth drives a different threat model than a generic British engagement — ITAR-aware supply chain risk, classified-network adjacency and insider-threat detection. Our scoping reflects that, and so does the test library we bring to the work.
Is Basalt set up for AI-era threats, not just legacy infrastructure?
Yes — this is core to how we work. Basalt actively researches and tests against agentic AI tool-abuse and indirect prompt injection at scale, MCP server and AI-tool supply chain compromise and identity-first attack chains across federated SaaS. Most regional providers haven't mapped these attack paths; we run them in production against client systems with explicit scope.
