RAG Pipeline Security Assessment

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

  1. 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.
  2. Mapping & discovery. Before touching anything we map the full attack surface in scope, so nothing exploitable slips through.
  3. Hands-on testing. Cyprus-based specialists exploit and chain weaknesses manually — the flaws scanners walk straight past — to show genuine impact.
  4. Reporting. Each issue is verified, CVSS-rated and documented with a step-by-step reproduction and a practical fix your team can apply.
  5. 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.

  • 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.
