Professional Penetration Testing Services
At Trilight Security, we provide penetration testing services encompassing web application penetration testing, mobile application penetration testing, network penetration testing, cloud penetration testing, API penetration testing, AI penetration testing, blockchain penetration testing, and TLPT pentests for organisations across the USA and the EU, including a strong focus on Germany. Our certified experts go beyond automated scanning — actively exploiting identified vulnerabilities, chaining attack paths, and demonstrating real business impact with proof-of-concept evidence. As cyber threats grow in sophistication and regulatory requirements tighten — with NIS2 Article 21, PCI-DSS, ISO/IEC 27001, and DORA all mandating regular security testing — independent penetration testing has become a core operational requirement, not an optional assurance exercise. Get in touch with Trilight Security to discover how our penetration testing services can strengthen your defences and satisfy your compliance obligations!
Our Offering
Black Box Pentesting
We provide black box pen testing services, when we have no access to the source code or internal design of the system, and rely on public information such as the system’s behavior, inputs, and outputs.
Grey Box Pentesting
We conduct grey box pentests where we are given partial information about the target — such as network diagrams, credentials, or API documentation — but without full access to source code or internal architecture.
White Box Pentesting
We conduct white box pentests, when we have complete information about the target system, including its architecture, source code, and access to sensitive data, to allow deeper examination.
We conduct simulated attacks on web applications using manual and automated techniques to identify security vulnerabilities that an attacker could exploit, and provide recommendations for remediation.
We assess AWS, Azure, and other cloud computing environments to identify vulnerabilities such as misconfigured access controls, weak authentication mechanisms, and insecure data storage, and provide recommendations for your IT team.
We assess networks, IT systems, and infrastructure to identify vulnerabilities such as misconfigured access controls, weak authentication mechanisms, unpatched systems, and others, reducing the risk of data breaches or other security incidents.
APIs are the most attacked and underestimated surface in modern software. Trilight Security specializes in API penetration testing services, helping businesses identify and remediate vulnerabilities in their REST, GraphQL, gRPC, SOAP, and WebSocket APIs.
Trilight Security specializes in AI penetration testing services, helping businesses and organizations identify security vulnerabilities in their AI systems, LLM-powered applications, and agentic AI deployments before they can be exploited.
Blockchain penetration testing is a security assessment in which our experts simulate real-world attacks against your smart contracts, DeFi protocols, blockchain infrastructure, and Web3 applications — identifying exploitable vulnerabilities.
Threat-Led Penetration Testing (TLPT) is a large-scale Red Team exercise that simulates all elements of a real attack against an organisation’s critical live production systems, using bespoke threat intelligence to replicate the TTPs of genuine threat actors.
Why Penetration Testing?
Web and mobile applications, APIs, cloud environments, and network infrastructure are among the most frequently targeted attack surfaces in modern organisations. The average cost of a data breach in Europe exceeded €4 million per incident in 2024 — yet the majority of breaches exploit vulnerabilities that a penetration test would have identified. A penetration test goes beyond automated vulnerability scanning: our experts actively exploit identified weaknesses, chain multiple vulnerabilities into realistic attack paths, and demonstrate exactly what an attacker could achieve in your environment. By identifying these weaknesses proactively, we help you prevent data breaches, protect user information, satisfy regulatory requirements, and give your board the independent assurance they need. For organisations subject to NIS2, PCI-DSS, ISO/IEC 27001, DORA, or HIPAA, penetration testing is not just best practice — it is a documented compliance requirement with enforcement consequences.
Penetration Testing Process
We use a combination of manual adversarial techniques and automated tooling to simulate real-world attacks against your systems. Our methodology is adapted to the specific target type, architecture, and compliance requirements of each engagement. Typically, penetration testing projects include the following stages:
- Information Gathering & Reconnaissance: We map the full attack surface — enumerating endpoints, technologies, credentials, and organisational structure through passive OSINT and active enumeration, depending on the agreed engagement type.
- Vulnerability Analysis: Using both automated scanning and manual inspection, we identify vulnerabilities across all in-scope assets — covering known CVEs in unpatched services, misconfigured access controls, insecure application logic, and weak cryptographic implementations. All automated findings are manually validated before inclusion in the report.
- Exploitation: We actively exploit identified vulnerabilities to demonstrate real-world impact — including injection attacks, authentication bypass, API authorization failures, and privilege abuse — producing proof-of-concept evidence for every finding.
- Privilege Escalation & Lateral Movement: We attempt to escalate from initial access to the highest available privilege level, moving laterally across networks or applications to reach the most sensitive assets — demonstrating the full blast radius of each vulnerability.
- Maintaining Access: We assess whether an attacker could establish persistence in the environment — through backdoors, rogue accounts, or living-off-the-land techniques — testing the visibility of your monitoring and detection capabilities.
- Reporting: Our reports are thorough, developer-friendly, and structured for both technical and executive audiences. Each report includes a detailed attack narrative, proof-of-concept evidence, prioritised remediation recommendations, and compliance mapping to OWASP, PTES, NIST SP 800-115, and applicable regulatory frameworks
