Endpoint and VDI Penetration Test

Penetration Testing of Endpoints and VDI is a specialized security service aimed at assessing the resilience of end-user devices and virtual desktop environments against real-world cyber threats. This type of test focuses on systems such as employee workstations, laptops, thin clients, and Virtual Desktop Infrastructure (VDI), which often represent the first line of defense in corporate networks and are frequent targets of attackers.

Objectives

The main objective is to identify and demonstrate security weaknesses that could be exploited by malicious actors to gain unauthorized access, escalate privileges, exfiltrate sensitive data, or move laterally within the internal network. Typical vulnerabilities include insecure configurations, missing updates, weak local credentials, improperly exposed services, misapplied group policies, or lack of hardening against known endpoint exploitation techniques.

Our testing methodology combines automated scans with manual techniques that simulate how attackers might target real users or devices in a corporate environment. We analyze the local attack surface of the operating system, installed applications, privilege escalation vectors, and possible breakout paths from virtualized desktop environments. Where applicable, we also test persistence mechanisms, data protection at rest, and endpoint logging capabilities.

In VDI-specific assessments, we evaluate isolation between user sessions, protections against hypervisor escape, and potential data leakage between virtual machines or user profiles. The test may also include evaluation of remote access policies, authentication methods (e.g., smart cards, MFA), and session hijacking possibilities.

We tailor the scope of the test based on the specific architecture and use cases of the client. For example, environments with bring-your-own-device (BYOD) policies, shared workstations, or administrative access from endpoints require special attention due to increased risk.

The final deliverable is a comprehensive report detailing all identified findings, risk classification, technical evidence, and clear recommendations for remediation or risk mitigation. The report is structured for both technical and managerial audiences, helping IT and security teams to prioritize and implement necessary improvements effectively.

This service is often recommended as a complementary activity to internal network penetration testing or in preparation for regulatory audits, such as those under NIS2 or DORA frameworks.

Other Types of Security Testing

In addition to the above described testing we provide our clients also with many other types of penetration tests – see Penetration Testing Overview.
