Security Testing

Find the holes before the bad guys do

Hands-on technical testing that goes beyond automated scans. Penetration testing, AI & LLM security testing, architecture reviews, and vulnerability assessments from security experts.

What You Get

Full technical validation of your security controls.

Penetration Testing

Ethical hacking to find vulnerabilities before real attackers do.

• Web application testing
• API security testing
• Network infrastructure testing
• Cloud environment testing

AI & LLM Penetration Testing

Assess the security of your AI systems, LLM integrations, and agentic workflows against the OWASP LLM Top 10.

• Prompt injection & jailbreak testing
• Tool-use & MCP server abuse vectors
• Data exfiltration via AI agents
• OWASP LLM Top 10 coverage

Security Architecture Evaluation

Defense-in-depth review of your security design.

• Network segmentation review
• Identity & access architecture
• Data flow analysis
• Security control validation

Vulnerability Assessment

Systematic identification and prioritization of security weaknesses.

• Infrastructure scanning
• Risk-based prioritization
• Remediation roadmap
• Executive summary report

Beyond the Health Check

While our Cyber Health Check gives you visibility into your overall posture, Security Testing goes deeper. We actively try to break in - so you can find and fix critical vulnerabilities before real attackers do, giving you time to fix any issues before they are used against you.

Frequently Asked Questions

What is the difference between a vulnerability assessment and a penetration test?

A vulnerability assessment uses automated scanning to identify known weaknesses. A penetration test goes further - our analysts manually attempt to exploit those weaknesses to verify which ones are actually exploitable and what damage a real attacker could cause. We always manually verify our findings, eliminating false positives from scanner output.

Does security testing disrupt our production systems?

We always scope testing carefully to minimize disruption. For production systems, we perform testing during low-traffic windows and use safe, non-destructive techniques. For more aggressive testing, we prefer to work against a staging environment. All rules of engagement are agreed before we begin.

How is AI and LLM testing different from traditional penetration testing?

AI systems require completely different attack techniques. We test for prompt injection, jailbreak exploits, training data poisoning, insecure output handling, and agentic workflow abuse - none of which traditional network or web app testing tools cover. We follow the OWASP LLM Top 10 methodology.

What do we receive at the end of the engagement?

You receive a technical report with all findings, proof-of-concept evidence, and specific remediation steps for your IT team - plus an executive summary for leadership showing risk severity and business impact. We also include a free retest within 6 months to validate your fixes.

Why D3 Cyber?

Business Logic Testing

Automated scanners miss logic flaws. We find the ways attackers can abuse your legitimate features.

Zero False Positives

We manually verify every finding. You don't waste time chasing ghosts or triaging scanner output.

Clear Remediation

We speak developer. Our reports give your team exact reproduction steps and code-level fix recommendations.

AI & LLM Security Expertise

We test against the full OWASP LLM Top 10 - from prompt injection and insecure output handling to training data poisoning and excessive agency.

MCP & Agentic AI Testing

We assess your MCP servers and agentic AI tool chains for unauthorized data access, privilege escalation, and cross-tool attack paths.

Free Retesting

Every engagement includes a free retest within 6 months - so you can validate your fixes and demonstrate progress to auditors.
