Architecting & Networking

Zero-trust architecture adoption has accelerated sharply as remote work and cloud adoption 
make traditional perimeter models obsolete. Organizations building or re-architecting their 
networks in 2024–2025 face the challenge of designing for security from the ground up  not 
bolting it on afterward.

Key Benefits

•Zero-trust architecture design and implementation guidance 
•Secure network segmentation and micro-segmentation strategy 
•Hybrid and multi-cloud connectivity design with security controls 
•DMZ, NAT, VPN, and SD-WAN security architecture review 
•Security requirements integration into IT project delivery

What We Do

Securiglobe’s Architecting & Networking service helps organizations design and implement 
secure, resilient network architectures. Whether you’re building a new environment, migrating to 
the cloud, or modernizing your infrastructure, our security architects work alongside your IT 
team to embed security principles into every layer.

How It Helps Your Business

Security that’s designed in costs a fraction of security that’s bolted on after the fact. 
Securiglobe’s architects help your team build environments that are resilient by design
supporting your business growth without creating new risk.

Our Approach

Planning & Objective Setting

We understand your business requirements, application dependencies, regulatory obligations, and current architecture through structured discovery workshops

Open Source Intelligence

For modernisation and redesign projects, we document and assess the current architecture identifying gaps, risks, and modernisation opportunities

Initial Access

We produce a target architecture design with multiple options where appropriate, covering network topology, security controls, connectivity, and resilience.

Initial Access

The design is reviewed by your technical and leadership teams. We facilitate a structured design review and incorporate feedback before finalisation.

Planning & Objective Setting

We produce an implementation plan with phased delivery, migration steps, cutover procedures, and rollback plans.

Open Source Intelligence

Our network engineers support or lead implementation configuring devices, deploying cloud architecture, and validating the build against the design.

Initial Access

Post-implementation testing validates that the architecture performs as designed connectivity, failover, security control effectiveness, and compliance alignment.

Frequently Asked Questions

Do you implement the architecture or only design it?

We offer both. Some clients engage us for design only and implement with their internal team or another vendor. Others engage us end-to-end for design and implementation. We are flexible based on your needs and existing capabilities.

Yes. We design around your existing technology investments where appropriate, and recommend changes only where the current technology cannot meet your security or performance requirements.

A focused network redesign engagement typically takes 4 to 8 weeks from discovery to final design. Cloud architecture engagements are typically 3 to 6 weeks. Implementation timelines depend on scope

Yes. Cloud migration architecture is one of our most common engagements. We design a secure, well-architected landing zone and application architecture for your target cloud platform, with a migration plan that maintains security throughout the transition

Deliverables

  • Current state architecture assessment (for redesign projects)
  • Target state architecture design document
