Penetration Testing Services to Identify

Real Attack Paths

See your business through an attacker's eyes. Identify exploitable vulnerabilities, attack paths, and business risks with independent penetration testing tailored to Swiss and EU regulatory expectations.

Our penetration testing services simulate realistic attack scenarios across your applications, infrastructure, and networks. We demonstrate how weaknesses can be chained together to compromise critical systems, then deliver a full report tailored to both technical and executive audiences, with prioritised recommendations aligned to business impact.

Security validation

Why Realistic Attack Simulation Matters for Business Security

Cyber threats are no longer a question of if but when. Penetration testing, also known as ethical hacking, simulates real-world attacks in a controlled and authorised way to identify exploitable weaknesses before attackers do. 

Unlike automated vulnerability scans, penetration testing is performed by certified experts who think and act like attackers. They chain vulnerabilities, bypass security controls, and attempt to reach your most sensitive assets, revealing the true business impact of your exposure.

Penetration testing is more than a technical exercise: it is a business risk management tool that supports audit readiness, investment decisions, and regulatory compliance.

Challenges

Penetration Testing Challenges and Cyber Risk Exposures

Many organisations invest in security controls but still lack visibility into whether those controls actually prevent real-world attacks. Without independent validation, common gaps emerge:

  • Unclear prioritisation of security investments, with budget spread across low-impact issues
  • Hidden attack paths across interconnected systems, applications, and identities
  • Increasing regulatory pressure, including the Swiss Federal Act on Data Protection (FADP), ISO 27001, and FINMA expectations
  • Late discovery of critical weaknesses during audits, customer assessments, or active incidents 
  • Limited understanding of business impact, such as data exposure, operational disruption, or reputational damage 

Acting before your next audit or security incident allows you to stay in control of your security posture, rather than reacting under pressure with limited time and options.

Attack Simulation

Choosing the Right Testing Approach for Your Environment

Penetration testing can be performed with different levels of prior knowledge and access. The right approach depends on your objectives, risk profile, and the scope of what you want to validate.

Black Box Minimal Knowledge

No internal information is provided. This simulates an external attacker with no prior knowledge and focuses on publicly exposed systems. It is efficient and realistic for perimeter testing but offers limited visibility into internal weaknesses.

Gray Box Partial Knowledge

Partial knowledge is shared, such as user credentials, network diagrams, or architecture insights. This simulates a compromised account or insider scenario and offers the best balance between realism and depth. It is often the most effective approach for identifying high-impact risks within a defined timeframe.

White Box Complete Knowledge

Full access to source code, configurations, and documentation is provided. This enables maximum coverage and is ideal for deep security assessments, critical applications, or integration into a secure development process.

Scope of Services

Security Testing Across Infrastructure, Applications, and Attack Surfaces

We deliver targeted penetration testing services tailored to your environment, industry, and business context.

Infrastructure Security

Validate that your network, endpoints, and wireless perimeter resist real attacks.

Internal Network Penetration Testing

Simulation of insider threats and assumed-breach scenarios, including privilege escalation, lateral movement, and attack paths leading to your critical assets. 

External Network Penetration Testing

Analysis of internet-facing systems and exposed services to identify entry points and real-world attack vectors before adversaries do. 

Wireless Penetration Testing

Assessment of Wi-Fi security, authentication protocols, rogue access point detection, and risks of unauthorised access to internal networks. 

Application Security

Validate that your customer-facing and integration layers resist real attacks.

Web Application Penetration Testing

In-depth assessment of application workflows, authentication, business logic flaws, and OWASP Top 10 vulnerabilities, with a focus on what attackers can actually exploit.

API Penetration Testing

Evaluation of REST, GraphQL, and SOAP endpoints, including authentication mechanisms, authorisation flaws, data exposure risks, and abuse scenarios aligned with the OWASP API Security Top 10.

Advanced and Optional Testing Scenarios 

Social engineering simulations and targeted attacker scenarios can be included depending on your threat model and risk exposure.

Methodology

How We Run a Penetration Test

Our methodology follows the Penetration Testing Execution Standard (PTES), the OWASP Web Security Testing Guide, and the MITRE ATT&CK framework, ensuring consistent, transparent, and audit-ready engagements from scoping to remediation.

Pre-engagement

Definition of scope, objectives, rules of engagement, legal authorisation, and testing windows, ensuring full alignment with your business and operational constraints. 

Intelligence Gathering

Attack surface mapping through OSINT, asset discovery, and reconnaissance to identify realistic entry points before testing begins. 

Threat Modelling

Identification of realistic attack scenarios based on your business-critical assets, threat landscape, and adversary profiles relevant to your industry. 

Vulnerability Analysis

Combination of manual testing and targeted automated techniques to identify exploitable weaknesses, with results validated to eliminate false positives. 

Exploitation

Controlled exploitation and chaining of vulnerabilities to demonstrate real impact, mapped to MITRE ATT&CK techniques for clear adversary alignment. 

Post-Exploitation

Simulation of realistic attacker behaviour, including privilege escalation, lateral movement, persistence, and access to sensitive data, to assess the true depth of compromise. 

Reporting

Delivery of a comprehensive report with executive and technical sections, validated evidence, business impact analysis, and a prioritised remediation roadmap. 

Deliverables

Penetration Testing Report and Remediation Support

Every engagement delivers a single comprehensive report designed for two audiences: an executive section for leadership and audit stakeholders, and a technical section for your security and engineering teams. Each engagement also includes a dedicated report presentation, with optional retesting available to validate fixes.

Executive Section

Designed for C-level, risk, and audit stakeholders, providing a clear view of business risk and remediation priorities. 

  • Overall security posture and risk assessment 
  • Business impact and potential consequences for your operations, data, and reputation 
  • Prioritised remediation plan aligned with business risk 
  • Key insights ready to support board, audit, and regulatory discussions 

Technical Section 

Designed for your security, engineering, and IT teams, providing the depth needed to understand and remediate each issue.

  • Complete list of findings with severity ratings and CVSS v3.1 scoring 
  • Mapped attack paths showing how findings chain to compromise critical assets 
  • Step-by-step reproduction evidence, including affected assets, requests, and proof of exploitation 
  • Concrete, actionable remediation recommendations with references to relevant standards (OWASP, CWE, vendor guidance)

Report Presentation 

Included with every engagement. A dedicated session with our consultants ensures all stakeholders, technical and executive, understand the findings, the underlying risks, and the recommended remediation priorities. Questions are addressed directly and remediation discussions can begin immediately. 

Optional Retest and Validation 

Available as an add-on. Once your teams have implemented fixes, our consultants verify that vulnerabilities have been effectively remediated, no regressions have been introduced, and the original attack paths can no longer be exploited. The retest concludes with an updated report reflecting your improved security posture. 

Business Impact

Our Security Testing Is Aligned with Operational Exposure

Attack paths, not just vulnerabilities

We focus on how weaknesses combine across systems to enable real compromise, because attackers exploit chains, not isolated findings. You see exactly how an issue in one component can lead to the loss of your most critical assets.

Realistic attacker objectives

Each engagement is driven by adversarial goals, such as domain takeover, data exfiltration, ransomware staging, or business service disruption. This produces findings that map directly to outcomes your leadership and auditors care about.

Focus on business-critical assets

Before testing begins, we identify your crown jewels with you, whether that means customer data, financial systems, intellectual property, or operational technology. Every test is then prioritised around protecting what matters most.

Clear, decision-ready reporting

You receive a single comprehensive report with two audience-specific sections: an executive summary for leadership and a detailed technical analysis for your security and engineering teams. Each finding includes validated evidence, business impact, and a prioritised remediation path.

Methodology-driven and standards-aligned

Our engagements follow the seven phases of PTES and align with the OWASP Web Security Testing Guide, ensuring repeatable quality and full coverage rather than ad-hoc testing.

Independent and certified expertise

Our team holds recognised offensive security certifications and operates independently of vendor or product sales, so our recommendations are guided by your risk, not by what we sell.
