Our social commitment

A school kit donated to a child for every training

To fight inequalities in access to education, Learni donates a complete school kit to a child in need for every training booked. You build your skills, a child heads back to school.

  • Backpack, notebooks and essential supplies
  • Distributed through our partner charities
  • Included, at no extra cost to you

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Don't let this gap widen

Why this program matters

  • Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Program

Module 1Fundamentals of Network Segmentation: Principles and Security Challenges 2026 (OSI Model, Basic VLANs)

Discovery of the essential concepts of network segmentation, analysis of lateral movement risks in modern breaches, hands-on with the OSI model to identify layers to segment, initial VLAN configuration on Cisco or open-source switches via Packet Tracer, practical exercises on a simulated enterprise network, creation of a first simple segmentation diagram with isolation of critical zones, discussion of real cases like 2025 ransomware attacks.

Module 2VLANs and Subnets in Network Segmentation: Logical Isolation (GNS3, IPAM Tools)

In-depth configuration of VLAN trunking and inter-VLAN routing, use of GNS3 to simulate a segmented enterprise network, definition of optimized subnets for DMZ, IoT, and critical servers, practical workshops on subnet masking and static routing, connectivity tests with ping and traceroute, production of a deliverable segmented IP plan, highlighting performance and security gains for 2026.

Module 3ACLs and Firewalls for Network Segmentation: Flow Control (pfSense, Cisco ACLs)

Learning access control lists to block unwanted flows, installation and configuration of pfSense for segmentation, writing standard and extended ACLs on virtual routers, MITM attack simulations to validate rules, exercises on prioritizing critical traffic, integration with SNMP for monitoring, development of a firewall rules playbook adapted to 2026 standards, demos of concrete attack surface reductions.

Module 4Zero Trust and Network Micro-Segmentation: 2026 Trends (Illumio, NSX)

Introduction to zero trust applied to network segmentation, exploration of micro-segmentation with VMware NSX or open-source tools like Cilium, modeling policies based on identities and East-West traffic, practical labs on segmented Kubernetes containers, implementation of SDP for granular access, case studies of enterprises migrated to zero trust, creation of a micro-segmentation matrix for hybrid infrastructure, anticipation of 2026 regulatory evolutions.

Module 5Deployment and Audit of Network Segmentation: Practical Cases 2026 (Wireshark, Nessus)

Synthesis with deployment of a complete network segmentation architecture in the lab, use of Wireshark to audit segmented flows, Nessus scans to detect residual vulnerabilities, performance optimization with segmented QoS, remediation exercises on real incident scenarios, finalization of the red thread project with a deliverable audit report, preparation for Qualiopi certification, personal roadmap for enterprise implementation starting in 2026.

Evaluation method

  • Multiple-choice quiz to validate learning outcomes at the end of the training
  • Continuous assessment through practical exercises
  • Presentation of the red thread project to the trainer

Learning method

  • Courses led by an expert trainer in active practice
  • Practical exercises based on real enterprise cases
  • Progressive red thread project throughout the training
  • Complete course materials provided to each participant

Methods, materials and delivery

The Training Network Segmentation - Securing Networks in 2026 program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training Network Segmentation - Securing Networks in 2026 program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Training Network Segmentation - Securing Networks in 2026 program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
