Networking & Cybersecurity Course in Kochi

From cabling to cybersecurity. This programme starts with the basics, like holding a crimper and recognising a cable, and ends with you securing and defending a full network. About 70% of the time is hands-on work in our Kochi lab, on real cables, racks, routers, switches and firewalls. It runs for 30 weeks in three levels. Level 1, Network Technician, takes 15 weeks. Level 2, Network Engineer, takes 10 more. Level 3, Cybersecurity, takes 5 more. Each level prepares you for its own job roles. You can stop after any level or carry on to the next one, and you pay only for the levels you take. Every week is built around a real-world job, set as a brief from a client. You work at a lab bench with a mentor, and the week ends with a handover you have to explain. Every module ends with a project for your portfolio: you cable an office floor, install internet and CCTV, build and fix a small office network (LAN), build a multi-site routed network, design a resilient branch network, and finally secure and defend a full network. Classes run 5 days a week, in English and Malayalam, in small batches of 12 trainees. If you have finished 12th, ITI or a diploma, you can start. Graduates and career-switchers join the same way. The lab is on South Janatha Road, Palarivattom, Kochi, and trainees from anywhere in Kerala can join. The routing and switching modules cover topics from Cisco's CCNA, and Level 3 prepares you for the CompTIA Security+ exam. Those exams are run by Cisco and CompTIA, are optional and are paid separately. Placement support is part of the programme: mock interviews, interview preparation, your portfolio of lab work, and connections to employers. CELSE Labs is an NSDC-approved training centre, and the networking curriculum is aligned to the NSQF, India's National Skills Qualifications Framework.

Eligibility: 12th pass, ITI or diploma (any stream). Graduates and career-switchers welcome. No computer background needed.

Frequently asked questions

What is the Networking & Cybersecurity Career Program?

It is a hands-on course at CELSE Labs, Kochi, that takes you from your first network cable to defending a real network. It runs for 30 weeks in three levels: Network Technician, Network Engineer and Cybersecurity. About 70% of the time is lab work on real equipment.

Do I need a degree or a computer background to join?

No. The course starts from the very basics, like holding a crimper and recognising a cable. If you have finished 12th, ITI or a diploma and can use a phone, you can start. Graduates and career-switchers join the same way.

How long is the course?

30 weeks in all. Level 1 takes 15 weeks, Level 2 takes 10 more and Level 3 takes 5 more. Classes run 5 days a week, in the classroom and lab at our centre on South Janatha Road, Palarivattom, Kochi.

What language are the classes taught in?

English and Malayalam.

Can I do just one level?

Yes. Each level prepares you for its own job roles, so you can stop after any level or carry on to the next. You pay only for the levels you take. To join Level 2 directly you need Level 1 or equivalent skills, and to join Level 3 directly you need Level 2 or equivalent skills.

What jobs does each level prepare me for?

Level 1 prepares you for cabling technician, FTTH (fibre broadband) field technician, CCTV technician and LAN support roles. Level 2 adds network administrator, junior network engineer and NOC engineer roles (a NOC is a network operations centre). Level 3 prepares you for entry-level SOC analyst roles (a SOC is a security operations centre) and junior security analyst roles.

What is the fee?

Each level is priced separately and you pay only for the levels you take; ask us on WhatsApp for the current fee and monthly plan of each level. The fee covers all lab equipment and consumables, mentor sign-offs and assessments, the certificates and placement support. The Cisco and CompTIA exams are optional and paid separately.

What will I build during the course?

Every module ends with a project you hand over to a "client". You cable an office floor, install a full internet and CCTV system, build and fix a small office network (LAN), build a multi-site routed network, design a resilient branch network, and secure and defend a full network.

Does the course prepare me for CCNA or CompTIA Security+?

The routing and switching modules cover CCNA topics, and Level 3 prepares you for the CompTIA Security+ exam. These exams are run by Cisco and CompTIA, not by CELSE Labs. They are optional and paid separately.

What certificate do I get?

A verifiable certificate for each level you complete, along with a portfolio of the lab projects you built and handed over.

Is CELSE Labs recognised?

Yes. CELSE Labs is an NSDC-approved training centre, and the networking curriculum is aligned to the NSQF, India's National Skills Qualifications Framework.

About CELSE Labs

CELSE Labs — the Centre for Experiential Learning and Skill Enhancement — is an NSDC-certified, ISO 9001:2015 certified skill training institute and an Accredited Training Partner of Medhavi Skills University. We work with commerce graduates, career changers and working professionals across Kerala who want a job in accounting, finance, compliance or data, and who need practical capability rather than another certificate.

Our training is experiential rather than lecture-based. Instead of textbook exercises, trainees operate the books, bank account, invoices and internal correspondence of simulated companies — M & M Technologies, Toy Kingdom and PetalSoft — where transactions arrive incomplete, out of order and occasionally wrong, exactly as they do in a real office. Trainees learn judgement by making decisions and correcting them, which is the part of the work that cannot be transferred by explanation.

Questions about a programme? WhatsApp us on +91 8007 980 000. Scholarships of up to 30% are offered on selected programmes through a free online scholarship test. 88 CELSE Labs alumni have been placed, and our named placement record includes alumni at HDFC, ICICI, Bajaj Finserv, Kotak Mahindra, Big Basket, Ford, Amrita Hospital and JRHA Accounting in the UAE.
