Services overview

What is External Penetration Testing?

At Vumetric, we offer External Penetration Testing services designed to simulate real-world hacking scenarios. By simulating the hacking techniques and exploits used by skilled hackers, our external penetration test includes a comprehensive security assessment that goes beyond simple automated vulnerability scans. The goal is to gain access to target systems under controlled conditions to evaluate the effectiveness of existing external network’s security posture

Our qualified penetration tester evaluate your security using industry-leading standards. We give you practical advice on how to strengthen your security measures, along with a step-by-step plan to fix any vulnerabilities we find. We don’t just identify security holes; we help you solve them. Plus, our external penetration tests meet key industry standards like PCI-DSS, ISO 27001, and SOC2. This means you’ll have all the documentation you need to meet these important compliance requirements.


Why Should you Perform External Penetration Testing?

  • Evolving cyber attacks
    Traditional security approaches often inadequately identify emerging vulnerabilities, leaving complex network infrastructures susceptible to modern cyber attacks.
  • Risk of exposed vulnerabilities
    The rising prevalence of public-facing devices and applications not only expands the attack surface but also complicates the effective management of vulnerabilities, particularly in the safeguarding of sensitive information.
  • Increasing cybersecurity requirements
    Compliance standards are increasing across all industries and frequently include external penetration test as a requirement.
  • Limitations in traditional security solutions
    Conventional security tools, like firewalls and antivirus software are generally ineffective, lacking comprehensive coverage against a broader range of vulnerabilities.

How Will External Pentesting Help Secure my External Network?

  • Gain Insight into Existing Risks
    Conduct an in-depth external penetration test that transcends basic automated scanning tools to offer a comprehensive security assessment of your external network.
  • Simulate Real-World External Threats
    Replicate hacking techniques and exploits, such as unauthorized access and software exploitation, to pinpoint your most vulnerable assets.
  • Benchmark Against Industry Standards
    Measure your external security posture against globally recognized security frameworks to gauge how well you’re doing in the larger landscape.
  • Adopt the Latest Best Practices
    Deploy robust security mechanisms to fortify your target systems against a spectrum of threats, both conventional and emergent, thereby minimizing the attack surface.

According to industry best practices, external pen testing should be performed at least annually to keep pace with evolving cyber threats. In addition, external pentesting is especially critical in certain scenarios, such as Before launching new systems on the public Internet, after significant network changes, before compliance audits, after security incidents, and before major business events such as M&A transactions. This approach ensures that your organization is consistently fortified against the latest hacking techniques and vulnerabilities.

Every year, our external penetration testing helps a wide range of organizations meet their compliance requirements.We do this by identifying and flagging critical vulnerabilities that require immediate attention. After the remediation process, we go one step further by conducting remediation testing to validate the fixes. Finally, we provide official attestation that the identified vulnerabilities have been successfully remediated. This end-to-end service enables organizations to efficiently meet and maintain compliance standards such as SOC2, ISO27001, PCI-DSS, etc..

The cost of a penetration test can vary significantly depending on the scope of the assessment.For external penetration testing, one of the most significant factors in the price is the number of IP addresses that need to be evaluated.

Yes, re-testing is included in each of our external pentesting projects at no additional charge to help organizations meet compliance requirements and successfully improve their external security, maximizing their return on investment.After our recommended mitigations and fixes have been implemented, we retest all of the critical and high-risk vulnerabilities we initially identified to ensure they have been adequately mitigated and no longer pose a threat to the organization.

Our certified penetration testers use globally recognized frameworks, such as the MITRE ATT&CK and OSSTMM testing methodologies, to provide an accurate snapshot of your current external cybersecurity risks that could escalate into an incident.Using a blend of manual and automated techniques, we not only identify vulnerabilities, we contextualize them.This helps our clients effectively allocate their IT and network security resources to protect sensitive data.


Internal pentesting is conducted from within the organization’s network by a tester who has access to the internal network. External pentesting is conducted from outside the organization’s network and simulates an attack on public-facing systems. The primary difference is the point of origin of the test, with internal testing being more focused on internal network security measures while external testing focuses on identifying vulnerabilities in systems that are accessible from the internet.
