Testing of external IT infrastructures with large IP networks

We regularly receive customer inquiries who would like to have their publicly accessible IT checked for vulnerabilities. Basically, the external IP addresses of the customer must be scanned for open ports to determine the attack surface" The required time for the scan to complete correlates with the number of IP addresses.

Especially for customers having hundreds of IPs and more, a complete TCP and UDP port scan can take several days to weeks despite multithreading and time tuning. In such cases, in consultation with our clients, we carry out the port scans before the actual penetration test, as we do not want to charge our pentester for waiting for scan completion - especially since the manual time required to carry out port scans can be neglected.

Penetration Testing

Since 2013, we have been conducting professional penetration tests. All engagements are performed in accordance with international standards and backed by years of operational experience in penetration testing, red teaming, and offensive security. Originally rooted in the payment, finance, and banking sector, we bring extensive experience in highly regulated and security-critical environments.

As a specialized provider for professional penetration testing, we clearly distinguish between vulnerability scans and actual penetration testing. Tools are used selectively and interpreted within a clear methodology. However, decisive insights usually result from structured manual identification and analysis. We identify technical and business-critical weaknesses and subsequently assess them in a structured way based on their real-world risk. Looking for a professionally conducted penetration test with traceable results? Then binsec is your partner.
