Assume breach.
Design for it.
No single control stops every attack. We design layered security architectures (combining defence in depth, deception technology, and security obscurity) so that when one layer fails, the next one holds.
Layered security, engineered for your threat model
Defence in Depth Architecture
No single control stops every attack. We design layered security architectures where each layer assumes the previous one has failed: so a breach at the perimeter does not mean a breach of your crown jewels.
Security Through Obscurity (as a Layer)
Obscurity alone is not security: but as one layer in a defence-in-depth strategy, it raises attacker cost and reduces attack surface visibility. We implement obscurity techniques that complement your primary controls without creating false confidence.
Security Control Mapping & Coverage
Most organisations have security controls but do not know what threats they actually cover. We map your controls against MITRE ATT&CK and your specific threat model: identifying gaps, overlaps, and misaligned investments.
Deception & Honeypot Engineering
Deception technology turns your network into a trap. We deploy honeypots, honey tokens, and deception infrastructure that detect lateral movement and insider threats: alerting on attacker activity that bypasses traditional controls.
Security Resilience & Recovery
Resilience means assuming breach and designing for recovery. We design security architectures that limit blast radius, enable rapid recovery, and maintain business continuity even when controls fail.
Threat Modelling & Risk-Based Design
Defence in depth requires knowing what you are defending against. We run threat modelling workshops that identify your most likely attack paths, highest-value targets, and the controls that will have the most impact.
Model, map, layer, test
Model
We model your threat landscape (who is likely to attack you, how, and what they are after) before designing any controls.
Map
Your existing controls are mapped against the threat model to identify gaps, overlaps, and misaligned investments.
Layer
We design and implement additional control layers that address the identified gaps: prioritised by risk and operational impact.
Test
Red team exercises and tabletop simulations validate that your layered defences hold up under realistic attack scenarios.
Know your threat model?
If not, that is where we start. A threat modelling session maps your attack surface, identifies your most likely adversaries, and prioritises the controls that will have the most impact.

Frequently asked questions
What does Netru's Defence in Depth service include?
Netru scopes Defence in Depth to your specific environment and delivers it hands-on: we identify the gaps, implement the controls directly rather than handing over a list of recommendations, and validate that they work. Security is not a project with an end date, we monitor continuously and keep the controls effective.
Who carries out Defence in Depth at Netru?
You work directly with a senior security engineer or compliance lead, no sales pipeline and no account managers between you and the people doing the work.
How quickly can Netru start on Defence in Depth?
We respond to every enquiry within one business day and return a scoped proposal with fixed pricing within 48 hours. Engagements start within 72 hours of sign-off.
