--- title: Research and Insights | Christian Bieg description: Christian assesses our customers’ systems for vulnerabilities, including web applications, IT infrastructures, IIoT environments, and mobile platforms. With a deep understanding of attacker techniques combined with hands-on experience in exploit development and cryptography, he reliably uncovers even complex security weaknesses. His broad background in cryptography, reverse engineering, and detection and response enables him not only to identify risks but also to assess them in their full technical and operational context. --- [![avantguard](https://avantguard.io/hs-fs/hubfs/LogoInverted.png?width=254&height=120&name=LogoInverted.png "avantguard")](https://avantguard.io?hsLang=en) - [Services](https://avantguard.io/en/services) - [About Us](https://avantguard.io/en/über-uns) - [Experience](https://avantguard.io/en/erfahrung) - [Career](https://avantguard.io/de/karriere) - [Research](https://avantguard.io/en/blog) - [Contact](https://avantguard.io/en/kontakt) En - [English](https://avantguard.io/en/blog/author/christian-bieg) - [German](https://avantguard.io/blog/author/christian-bieg) [![avantguard](https://avantguard.io/hs-fs/hubfs/LogoInverted.png?width=144&height=65&name=LogoInverted.png "avantguard")](https://avantguard.io?hsLang=en) [![Dark-logo-small-1](https://www.fthemes.net/hubfs/Dark-logo-small-1.png "Dark-logo-small-1")](https://avantguard.io?hsLang=en) - [Services](https://avantguard.io/en/services) - [About Us](https://avantguard.io/en/über-uns) - [Experience](https://avantguard.io/en/erfahrung) - [Career](https://avantguard.io/de/karriere) - [Research](https://avantguard.io/en/blog) - [Contact](https://avantguard.io/en/kontakt) En - [English](https://avantguard.io/en/blog/author/christian-bieg) - [German](https://avantguard.io/blog/author/christian-bieg) [![avantguard](https://avantguard.io/hs-fs/hubfs/LogoInverted.png?width=144&height=65&name=LogoInverted.png "avantguard")](https://avantguard.io?hsLang=en) - [Services](https://avantguard.io/en/services) - [About Us](https://avantguard.io/en/über-uns) - [Experience](https://avantguard.io/en/erfahrung) - [Career](https://avantguard.io/de/karriere) - [Research](https://avantguard.io/en/blog) - [Contact](https://avantguard.io/en/kontakt) Current language: English - [English](https://avantguard.io/en/blog/author/christian-bieg) - [German](https://avantguard.io/blog/author/christian-bieg) Filter by tag All Offensive Red Team Research Covenant Bypass AI Cleartext Credentials Defensive News AD CS Active Directory Conti HTB Keepass PingCastle PowerShell Pro Labs Ransomware Review Shares Snaffler ![](https://avantguard.io/hubfs/AboutUs/Christian%20Bieg-1.jpg) ### Christian Bieg Christian assesses our customers’ systems for vulnerabilities, including web applications, IT infrastructures, IIoT environments, and mobile platforms.
