Frequently Asked Questions
Everything you need to know about external penetration testing services and our process.
External penetration testing is a cybersecurity assessment that evaluates your organization's public-facing systems and networks from an attacker's perspective. Our certified ethical hackers attempt to identify and exploit vulnerabilities in your external infrastructure, including websites, email servers, remote access points, and other internet-facing assets.
The duration depends on the scope and complexity of your external infrastructure. Typically, external penetration tests take 5-10 business days for testing execution, plus 1-2 days for planning and 3-5 days for reporting. We provide daily updates during testing and immediate notification of critical findings.
You'll receive a comprehensive report including an executive summary, detailed technical findings, risk ratings, proof-of-concept exploits, and prioritized remediation recommendations. We also provide a remediation roadmap with timelines and offer post-test support to help address identified vulnerabilities.
External penetration testing is designed to minimize business disruption. We coordinate testing schedules with your team, can restrict testing to business hours if needed, and use controlled testing methods. However, we may discover vulnerabilities that could temporarily affect services, which we'll communicate immediately.
While vulnerability scanning is automated and identifies potential vulnerabilities, penetration testing involves manual exploitation attempts by skilled security professionals. External pen testing provides deeper analysis, validates vulnerabilities, demonstrates real-world impact, and shows how multiple vulnerabilities can be chained together for greater impact.
We recommend annual external penetration testing as a baseline, with additional testing after major infrastructure changes, new application deployments, or security incidents. Organizations with high-risk profiles or strict compliance requirements may benefit from semi-annual testing.
We need your public-facing IP ranges, domain names, any testing restrictions or blacklisted systems, preferred testing windows, emergency contact information, and any specific compliance requirements. We'll also need a signed authorization letter before beginning any testing activities.
Yes, our penetration testing team holds industry-leading certifications including CISSP, CEH, OSCP, and GPEN. All testers have extensive real-world experience and follow established methodologies like OWASP, NIST, and PTES. We maintain strict quality standards and continuous professional development.
Our external penetration testing meets requirements for PCI DSS, HIPAA, SOX, NIST Cybersecurity Framework, ISO 27001, and other major compliance standards. We provide compliance-focused reporting and can customize our approach to meet specific regulatory requirements.
Yes, we offer comprehensive post-test support including remediation guidance, re-testing of fixed vulnerabilities, security awareness training, and ongoing security consulting. Our goal is to not just identify issues but help you improve your overall security posture.
