Cisco Blogs

Karsten Iwen


I started my work in the IT at about 1995/1996 as a freelance Trainer and consultant with a focus on networking, Novell NetWare and Microsoft Backoffice. In 2001 I started teaching Cisco classes at Global Knowledge in Germany. Since 2003 I'm again Freelancer with a strong focus on security technologies and infrastructure.
And yes, you can hire me for your security-projects and -workshops. ;-)
