An AI agent that can browse, run code or move data becomes an insider the moment it ingests attacker-controlled input. As Cyprus fintech and SaaS firms adopt autonomous AI, we test these systems end to end — the model, its tools, its memory and the boundaries between them.
We attempt tool-use abuse, goal hijacking and sandbox escape to show exactly what a compromised agent could do in your environment.
What we test
- Tool-use & function-calling abuse
- Goal hijacking & instruction override
- Privilege escalation through agent tools
- Sandbox & code-execution escape
- Cross-agent & memory poisoning
- Data exfiltration via agent actions
Common vulnerabilities we uncover
- Tool-use abuse leading to unauthorized actions
- Goal hijacking via injected instructions
- Excessive agency and over-broad tool permissions
- Sandbox and code-interpreter escape
- Cross-agent memory and context poisoning
- Sensitive data exfiltration through agent tools
How we run your AI Agent Penetration Testing
- Kick-off & scoping. A short call to agree goals, in-scope assets and rules of engagement, so your ai agent penetration testing 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
- Agent threat model & attack map
- Exploitation PoCs with impact
- Guardrail & tool-scope recommendations
- Free retest after remediation
Your deliverables
When your ai agent penetration testing 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 ai agent penetration testing, 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 ai agent penetration testing 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.
