Built for tech
Basalt's Tech City London practice has been working tech 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.
Tech City London, United Kingdom
Code Security Audit in Tech City London.
If your tech business sits in Tech City London, the threat profile is CI/CD supply chain compromise, OAuth token theft and AI/LLM prompt injection at scale. Basalt's code security audit practice is built around exactly that. Manual and tooled code review across your highest-risk repos — secrets, auth, injection, deserialisation and supply-chain risk, with CI integration that keeps findings from coming back.
85% of findings ship with a working patch suggestion — across Basalt operations in the past 12 months.
THREAT VECTOR
Threats facing Tech City London tech.
The tech, fintech, AI startups concentration around Tech City London sees CI/CD supply chain compromise, OAuth token theft and AI/LLM prompt injection at scale. Our code security audit work in London / Old Street – Shoreditch is scoped against this real threat profile, not a generic checklist.
Common pains
- Tools that report thousands of low-quality findings
- No clear ownership for fixing vulnerabilities in code
- Supply-chain risk in third-party dependencies
ENGAGEMENT
How we engage.
- Manual review of high-risk code paths
- SAST + SCA integrated into CI with quality gates
- Threat model per service or repository
- Developer-grade fix guidance with sample patches
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 code security audit to organisations across Tech City London and the wider London / Old Street – Shoreditch region (population ~40k). The tech, fintech, AI startups sectors that anchor the region face a distinct threat profile — CI/CD supply chain compromise, OAuth token theft and AI/LLM prompt injection at scale — 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 code security audit in Tech City London.
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 tech 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 code security audit engagement in Tech City London?
Most Tech City London 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 code security audit on-site in Tech City London or remote?
Both. Sensitive work — classified-adjacent environments, live incident response, OT walkthroughs — gets on-site time in Tech City London and the wider London / Old Street – Shoreditch 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 code security audit in Tech City London different from a generic engagement?
The tech sector concentration in Tech City London drives a different threat model than a generic British engagement — CI/CD supply chain compromise, OAuth token theft and AI/LLM prompt injection at scale. 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.
