ENSA: Certified Network Security Administrator Boot Camp


This five-day course looks at the network security in defensive view. The ENSA program is designed to provide fundamental skills needed to analyze the internal and external security threats against a network, and to develop security policies that will protect an organization’s information. Students will learn how to evaluate network and Internet security issues and design, and how to implement successful security policies and firewall strategies. In addition, they will learn how to expose system and network vulnerabilities and defend against them.

The EC-Council's NSA certification looks at the network security in defensive view while the CEH certification program looks at the security in offensive mode. The NSA program is designed to provide fundamental skills needed to analyze the internal and external security threats against a network, and to develop security policies that will protect an organization’s information. Students will learn how to evaluate network and Internet security issues and design, and how to implement successful security policies and firewall strategies. In addition, they will learn how to expose system and network vulnerabilities and defend against them.

This course prepares students for EC-Council Exam 312-38 ENSA.

By far the most competitve price we found, which included exam vouchers, hands on labs, practice test and a true Master of Cyber Security concepts as our Instructor. Franklin Mesa was the best trainer I have ever had and i walked out certified on the last day of my CompTIA Security+ certification bootcamp. 

Marc Alfonso - CompTIA Security + Student


The Academy is one of the best educational values for today's job market.  I studied hard and got certified (A+ and N+).  Even though I had no prior IT experience, I now have a good job replacing obsolete computers in hospitals throughout the country.  At my job interview, I just slid my test scores and certification across the table to the interviewer, who is now my boss.  I was hired the next day.  

Not bad for a 65 year old.

John Arnett- Student 

"I congratulate The Academy for a great facility and good lab computers. The Academy is great and I will definitely be taking more courses and utilizing the services available. Omer Palo is an excellent instructor that truly knows his material. I never felt bored in his class which is a first for me. Thank You."

IT Director, Burger King Corporation

"The instructor Frank Martinez is excellent – he covered so much material in 2 weeks that was unbelievable! He definitely knows what he does and it shows in the way that he conducts each lecture. He is the greatest!"
"Thanks Academy for allowing me to experience the MCSA / MCSE + Security Boot camp."
