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
Incident Response in Portsmouth.
What defence teams in Portsmouth actually need from incident response isn't another vendor pitch — it's a senior consultant who's already worked the same threat profile elsewhere in United Kingdom. Incident response and retainer services for the moments where minutes matter — containment, forensics, communications and lessons-learned, on call when the page fires.
Median containment under 90 minutes on retainer — 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 incident response work in South East is scoped against this real threat profile, not a generic checklist.
Common pains
- No clear answer to "who do we call at 2am"
- IR plans that have never been tested under pressure
- Forensic capability stitched together during the incident
ENGAGEMENT
How we engage.
- Retainer with named responders and SLA
- Tabletop and live-fire exercises tied to your tech stack
- Forensic readiness review across endpoints and cloud
- Post-incident review with engineering-grade root cause
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 incident response 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 incident response 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
Incident Response 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 incident response 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 incident response 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 incident response 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.
