Cardiff, United Kingdom

Penetration Testing in Cardiff.

Cardiff finance organisations face wire-transfer fraud, instant-payment abuse and identity-driven account takeover. Basalt's penetration testing practice tests against that real threat profile, not a generic United Kingdom-wide playbook. CREST-aligned penetration testing for web apps, APIs, internal networks and cloud environments — findings ranked by exploitability, not just CVSS.

Median time-to-first-finding under 6 hours — across Basalt operations in the past 12 months.

Threats facing Cardiff finance.

The finance, media, government concentration around Cardiff sees wire-transfer fraud, instant-payment abuse and identity-driven account takeover. Our penetration testing work in Wales is scoped against this real threat profile, not a generic checklist.

Common pains

  • Audit-driven testing that misses real attack chains
  • Findings without business context or fix guidance
  • Retesting that takes weeks to schedule

How we engage.

  • Scoped engagement plan with rules of engagement
  • Findings prioritised by exploitability and blast radius
  • Executive summary suitable for the board and regulators
  • Free retest of fixes within 90 days

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.

Basalt delivers penetration testing to organisations across Cardiff and the wider Wales region (population ~370k). The finance, media, government sectors that anchor the region face a distinct threat profile — wire-transfer fraud, instant-payment abuse and identity-driven account takeover — 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.

Why Basalt for penetration testing in Cardiff.

Built for finance

Basalt's Cardiff practice has been working finance 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.

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 finance 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.

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.

Frequently asked questions.

How fast can Basalt start a penetration testing engagement in Cardiff?

Most Cardiff 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 penetration testing on-site in Cardiff or remote?

Both. Sensitive work — classified-adjacent environments, live incident response, OT walkthroughs — gets on-site time in Cardiff and the wider Wales 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 penetration testing in Cardiff different from a generic engagement?

The finance sector concentration in Cardiff drives a different threat model than a generic British engagement — wire-transfer fraud, instant-payment abuse and identity-driven account takeover. 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.
