We don’t do green lights or paper reports.
We show what’s actually exploitable
and how to fix it.
For AI applications, we combine manual verification, source code analysis (when available), and runs of autonomous pentest agents such as CAI to increase coverage.
Industries We Protect
As AI becomes part of critical systems, our pentesting is built for high-risk industries, enterprise SaaS, and teams launching AI copilots, agents, and RAG features who need security they can rely on
What We Test
We test the parts of your AI stack that break in the real world.
LLM applications
- Conversation flows, safety controls, abuse handling
- Authentication, sessions, rate limiting
AI agents (planner, memory, tools)
- Permission misuse and goal hijacking
- Task queue manipulation and cross-agent escalation
RAG pipelines
- Retriever setup, chunking and metadata hygiene
- Vector database boundaries and query isolation
Model interfaces
- Prompt injection and jailbreaks
- Model extraction via crafted queries (when in scope)
Tools, plug-ins, and APIs
- Keys and secrets in context
- Unsafe action invocation and lateral movement
Cloud and secrets surface
- Buckets, logs, and telemetry that leak data
- Prompt and context redaction for PII/PHI where relevant
Our Approach
We build trust in your technology. The goal is simple: reduce unknown vulnerabilities, protect valuable data, and keep your product reliable and safe.
Methodologies
We don’t just name-drop frameworks — we apply them in every AI pentest. Our work is guided by proven security standards and adapted to the unique risks of AI systems. Every engagement ends with a clear checklist and threat model so you know exactly what was tested and why it matters.
For AI and LLM systems, our process includes:
OWASP LLM Top 10 — full checklist coverage for AI-specific vulnerabilities
PTES — comprehensive pentest execution framework
OWASP AI Testing Guide — comprehensive testing framework for AI system security
OWASP ASVS & WSTG — for supporting application security layers in AI stacks
NIST AI RMF — aligning outcomes to recognized AI risk management principles
How It Works
Cybersecurity is complex. Your path to enterprise readiness doesn’t have to be.
From Findings to Peace of Mind
You get a report that engineers can act on and leaders can trust.
Representative Findings (anonymized)
Real examples of issues we’ve identified and helped clients fix.
Each one shows the kinds of vulnerabilities that can slip through without focused AI/LLM security testing.
Agent Tool Misuse
Unauthorized Data Access
What we tested:
A support copilot with search and file retrieval tools.
What we did:
Steered the agent into triggering a high-permission tool without checks.
What we found:
Access to invoices and configuration files containing environment variables.
Why it mattered:
Allowed sensitive data exfiltration via “helpful” tool misuse.
Fix implemented:
-
Least privilege for tools
-
Pre-execution guardrails
-
Output sanitization
-
Abuse simulations in testing
RAG Namespace Escape
Cross-Tenant Data Leakage
What we tested:
Multi-tenant knowledge assistant using a shared vector database.
What we did:
Crafted queries exploiting missing tenant filters.
What we found:
Snippets from another tenant’s documents in responses.
Why it mattered:
Violated data isolation, risking regulatory breaches and trust.
Fix implemented:
-
Strict metadata and namespace isolation
-
Per-tenant database collections
-
Application-layer filter enforcement
-
Filter validation in CI/CD

What Our Clients Say
We felt that Sekurno really checked every bit and piece of our system.
This was evident in the deliverables they provided, with full transparency — including the testing status of each OWASP WSTG requirement and testing logic informed by their own threat modeling.
They were also the only team that advocated for a white-box approach — giving their security engineers deeper visibility into our application’s implementation and design, which can ultimately help with uncovering meaningful issues. It made the entire process feel aligned with how we actually build and operate.
