Decision-first scoping
Before a single test runs, we agree the decision the output will change — invest, divest, accept, fix. Portsmouth engagements without a named decision-maker don't get past scoping. That discipline keeps work focused.
Portsmouth, United Kingdom
Cloud Security in Portsmouth.
What defence teams in Portsmouth actually need from cloud security isn't another vendor pitch — it's a senior consultant who's already worked the same threat profile elsewhere in United Kingdom. Cloud security across AWS, Azure and GCP — identity, network, data and workload — with CSPM/CNAPP tuned to your environment rather than dropped in as-is.
Average 60% reduction in over-privileged cloud identities — 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 cloud security work in South East is scoped against this real threat profile, not a generic checklist.
Common pains
- CSPM tools generating findings nobody owns
- IAM sprawl across accounts and tenants
- No clear answer to "what would a breach cost us in the cloud"
ENGAGEMENT
How we engage.
- Cloud landing zone and guardrail review
- IAM least-privilege program with measurable progress
- Workload and data classification with control mapping
- Cloud incident response runbooks tested under load
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 cloud security 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 cloud security in Portsmouth.
Regulator-ready output
Every finding is tagged against NCSC Cyber Assessment Framework and UK GDPR controls with NCSC UK guidance cited where it shifts a remediation priority. Your compliance team stops re-mapping our reports.
Continuous, not one-shot
Cloud Security doesn't end at the report. Basalt's Portsmouth clients run retainer reviews on a quarterly cadence so the security posture compounds rather than drifting back six months after the engagement.
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 cloud security 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 cloud security 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 cloud security 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.
