Retrieval-augmented generation trusts its knowledge base by default — exactly what attackers exploit. We review ingestion, embedding, retrieval and generation for poisoning, leakage and access-control failures, for Cyprus AI products.
We test whether malicious content in your sources can steer the model, and whether users can retrieve data they shouldn't — a common, serious finding.
What we test
- Vector-store & document poisoning
- Retrieval-based prompt injection
- Cross-tenant context leakage
- Access-control gaps on sources
- Embedding & similarity manipulation
- Source spoofing & citation abuse
Common vulnerabilities we uncover
- Vector-store and document poisoning
- Retrieval-triggered indirect prompt injection
- Cross-tenant context and data leakage
- Access-control bypass on retrieved sources
- Embedding and similarity manipulation
- Source spoofing and citation abuse
How we run your RAG Pipeline Security Assessment
- Kick-off & scoping. A short call to agree goals, in-scope assets and rules of engagement, so your rag pipeline security assessment is safe, authorised and aimed at your real business risk.
- Mapping & discovery. Before touching anything we map the full attack surface in scope, so nothing exploitable slips through.
- Hands-on testing. Cyprus-based specialists exploit and chain weaknesses manually — the flaws scanners walk straight past — to show genuine impact.
- Reporting. Each issue is verified, CVSS-rated and documented with a step-by-step reproduction and a practical fix your team can apply.
- Free retest. Once you have remediated, we re-test at no extra cost to confirm the attack path is truly closed.
What you receive
- RAG pipeline threat model
- Poisoning & leakage PoCs
- Access-control hardening plan
- Free retest after remediation
Your deliverables
When your rag pipeline security assessment wraps up, you receive a clear, audit-ready report plus a walkthrough call with your team. Inside you will find:
- A concise executive summary that management and the board can act on
- Every technical finding with a reproducible, copy-paste proof of concept
- CVSS v3.1 ratings and plain-language business impact for each issue
- Practical, prioritised remediation your developers can implement straight away
- A free retest and updated finding status once fixes are in place
- A signed attestation letter for clients, auditors, GDPR, NIS2 and ISO 27001

What you gain
By the end of your rag pipeline security assessment, you will know exactly which weaknesses a real attacker could exploit, what it would cost your business, and the precise order in which to fix them — backed by evidence, not a scanner’s guesswork. Cyprus firms use our findings to close critical gaps, satisfy client and regulator security questionnaires, and demonstrate due diligence for GDPR and NIS2. With a free retest included, you also get documented proof the issues are resolved.
Working with us
Every rag pipeline security assessment begins with a short, no-obligation scoping call to understand your goals, environment and constraints, followed by a fixed-price proposal. Most work is delivered remotely, and because we are based in Cyprus we work in your timezone with on-site visits across Limassol, Nicosia and island-wide where it helps. We keep you updated throughout and flag any critical finding immediately rather than waiting for the report. Everything is covered by a signed NDA and safe, non-disruptive testing that protects your production systems. You receive your report, a walkthrough and a complimentary retest once fixes land. Engagements are typically booked one to three weeks ahead, and urgent testing can often be arranged — just email hi@cypruspentest.com.
Why Cyprus businesses choose CyprusPentest
Your rag pipeline security assessment is run by senior offensive-security specialists who test the way genuine attackers do — manually, creatively and focused on proving real impact. What sets us apart:
- Based in Cyprus — local, in your timezone, with on-site coverage across Limassol and Nicosia.
- Manual, exploit-led testing that chains vulnerabilities the way an attacker would, well beyond automated scanners.
- Reproducible proof for every finding, with copy-paste steps your team can independently verify.
- Compliance-ready reporting that supports GDPR, NIS2, ISO 27001 and CySEC expectations.
- A free retest so you have documented evidence your fixes actually hold.
- Fixed-price and responsive, with a named point of contact from scoping through to retest.

Frequently asked questions
Can users retrieve other tenants' data?
Frequently, yes — cross-tenant retrieval leakage is one of the most serious RAG findings.
Which vector stores do you support?
Pinecone, Weaviate, pgvector, Milvus, Qdrant and Elasticsearch.
Do you test with our data?
Sanitised production or synthetic data, per your data-handling rules, under NDA.
