Emerging

AI Security

The attack surface has expanded. LLMs, ML pipelines, and AI-powered products introduce entirely new classes of vulnerability. We're at the frontier of securing them.

LLM red-teaming and jailbreak testing
Prompt injection and indirect prompt injection audits
RAG pipeline security and data exfiltration testing
Adversarial machine learning and model evasion
AI supply chain and dependency risk assessment
Agent security — tool misuse and privilege escalation
OWASP LLM Top 10 compliance review

Client Feedback

What Clients Say

OakSprint's application security review uncovered a chained API vulnerability our internal team had completely missed. The depth of testing was unlike anything we'd seen from previous vendors.

James Roper

CISO — Fintech Scale-up

The AI security assessment opened our eyes to risks in our LLM pipeline we had completely overlooked. The prompt injection and RAG exfiltration scenarios were creative and alarming.

Sarah Lin

Head of Security — AI Platform

From scoping to remediation support, the process was seamless. The report quality alone justified the investment — clear, prioritised, and immediately actionable by the engineering team.
