Telecom & Critical Infrastructure

Cybersecurity testing for critical infrastructure.

Assess the security of your networks and critical systems before a cyberattack leads to a service outage or data loss. Independent penetration testing services supporting NIS2 and ISO 27001 compliance, from experienced specialists.

Compliance

Regulatory and standards-based compliance.

Because of their complex network environments and external connections, telecom and critical systems face a growing risk of cyberattacks and data security failures. Regular, independent testing lets you uncover and address these risks in time.

NIS2 Directive

Directive (EU) 2022/2555 requires risk-based information security measures, vulnerability management and verifiable protection mechanisms. Telecom and critical infrastructure organisations fall squarely within its scope.

ISO 27001

The international standard for information security management systems requires a risk-based approach to protecting data and systems. Our assessments show where controls still need strengthening, and our report can also be used as evidence in ISO 27001 audits.

Available security assessments

We test the way real attackers work.

To uncover the security risks of telecom and critical infrastructure systems, we provide a range of targeted penetration tests and attack simulations. These assessments help identify critical vulnerabilities and support regulatory compliance. At the end of the engagement, you and your organisation receive a comprehensive report that supports strategic decision-making.

Infrastructure testingComprehensive security testing and vulnerability assessment of external and internal network infrastructure, servers and critical systems. Thorough analysis, transparent results.
Wireless testingSecurity testing of wireless networks to identify unauthorised access, configuration errors and eavesdropping risks.
API security testingTesting the APIs of network services and system integrations to uncover authentication flaws and data leakage risks.
Web application testingIdentifying vulnerabilities in customer portals, network management interfaces and web administration systems through manual penetration testing.
Red teamingSimulating real attack scenarios to assess your organisation’s full defensive capability, including how quickly an attack is detected and stopped.
Phishing simulationSimulating phishing attacks to assess employee security awareness and the response of staff who operate critical systems.
Process

The security assessment process.

Whiteshield’s penetration testing process provides a transparent, structured framework for assessing the security of telecom and critical infrastructure systems.

  1. Step 01

    Consultation and needs assessment

    We get to know the network environment, the systems involved and the applicable security requirements.

  2. Step 02

    Defining the scope

    We define the exact scope of the assessment, the systems involved, the methods and the schedule.

  3. Step 03

    Security testing

    We carry out a controlled penetration test to identify attack paths and segmentation gaps.

  4. Step 04

    Report and recommendations

    We document the vulnerabilities found and give concrete recommendations to reduce the risks.

Consultation

Security starts with a conversation.

No sales pitch – just a focused conversation about your business continuity and operational risk.
