The Certified Network Defender (CND) certification program focuses on creating Network Administrators who are trained on protecting, detecting and responding to the threats on the network. The course has been mapped to global job roles and responsibilities and the Department of Defense (DoD) job roles for system/network administrators.
We offer flexibility. You can choose from our selection of in-class courses as well as online courses.

Organizations can be much better in defending themselves from vicious attacks if the IT and network administrators equipped with adequate network security skills. Thus Network administrator can play a significant role in network defense and become first line of defense for any organizations.

This is the world’s most advanced Certified Network Defense course with 14 of the most current network security domains any individuals will ever want to know when they are planning to protect, detect, and respond to the network attacks.
For twenty years he worked where IT really breaks: he administered thousands of servers, designed networks for T-Mobile, built branch infrastructure from Ukraine to India and managed the migration of 60,000 computers for Société Générale. DHL contracted him into its security teams three times. He therefore knows the attacker not from slides but from his own incidents: he knows which doors lead into a company because he guarded them for years.
What is his course like?
As a Certified EC-Council Instructor (CEI) he teaches ethical hacking and cyber defence courses by the official EC-Council methodology, but he does not read them out. He demonstrates every phase of an attack live, from reconnaissance through gaining access to covering tracks, and immediately adds the defence: what the administrator will see in the log, which control stops the attack and why most companies do not have it. His Certified Ethical Hacker (CEH), Certified Network Defender (CND), EC-Council Incident Handler (ECIH) and CCISO certifications let him cover the whole cycle: attack, defence, incident response and the management view.
His trademark is practical demonstrations built on a simple principle: maximum effect with minimum resources. No theatre with million-dollar labs, but procedures a participant can repeat in their own environment the very next day. On top of that, three things an online course cannot offer: teaching in Czech, groups of 7 to 12 people and dialogue. You can ask about situations from your own company and get an answer from someone who has most likely dealt with a similar one.
