The Cisco CCIE Security certification trains security professionals to manage and develop end-to-end secure networks by teaching them how to architect, engineer, implement, troubleshoot, and maintain the whole Cisco security technology and solution suite.

The programme will teach professionals how to defend systems and environments against modern security risks, vulnerabilities, and requirements by utilizing best industry practices.

To obtain the CCIE Security certification, a candidate must pass the following exam(s):

  • 400-251 CCIE Security Written Exam
  • CCIE Security Lab Exam Version 5.0

Overview of the Exam

Cisco network security products, solutions, and technologies such as next-generation intrusion prevention, next-generation firewalls, identity services, policy management, device hardening, and malware protection, as well as network functionality and security ideas and best practices, are discussed.

The unified test topics are used in the written exam, which encompass upcoming technologies such as cloud computing, network programmability (SDN), and the Internet of Things (IoT).


The first step is to take the written CCIE Security exam.

Before scheduling the lab exam, you must first complete a two-hour written qualifying exam covering network security concepts and some equipment instructions.


Step two is to take the CCIE Security exam.

The lab exam lasts eight hours and examines your ability to build up a secure network in a timed test scenario. The CCIE lab test must be taken for the first time within 18 months of passing the CCIE written exam. In order for their written exam to be legitimate, candidates who do not pass the lab exam must retake it within 12 months after their last successful try. If you fail the lab exam after passing the writing exam within three years, you must retake the written exam before attempting the lab exam again.
