ServicesNetwork Security

Defend the network.
Understand it first.

Network security is not just firewalls. We design, harden, and monitor network architectures (from perimeter controls to east-west segmentation) for cloud, on-premises, and hybrid environments.

Network security across every layer

Network Architecture

Secure Network Architecture

Network security starts at the design stage. We review and redesign network architectures (segmentation, trust zones, east-west traffic controls, and zero-trust network access) for on-premises, cloud, and hybrid environments.

Perimeter Security

Perimeter Defence & Hardening

The perimeter is not dead: it is just more complex. We design and harden perimeter controls including next-generation firewalls, IDS/IPS, DMZ architecture, and ingress/egress filtering across your entire network boundary.

Network Monitoring

Network Traffic Analysis & Monitoring

You cannot defend what you cannot see. We deploy network monitoring solutions that provide full visibility into traffic flows, detect anomalies, and alert on lateral movement: without creating performance bottlenecks.

VPN & Remote Access

Secure Remote Access

Remote access done wrong is a breach waiting to happen. We design and implement secure remote access solutions (from traditional VPN hardening to modern ZTNA) with MFA, device posture checks, and least-privilege access.

DNS Security

DNS Security & Filtering

DNS is one of the most abused protocols in attacker toolkits. We implement DNS security controls (filtering, monitoring, DNSSEC, and DNS-over-HTTPS) to block C2 communications, data exfiltration, and phishing at the protocol level.

Network Penetration Testing

Network Penetration Testing

We attack your network the way a real adversary would: from external reconnaissance through to internal lateral movement. Manual testing by engineers who understand network protocols, not automated scanner output.

Map, assess, harden, validate

01

Map

We map your network topology, traffic flows, and existing controls before recommending any changes.

02

Assess

Gap analysis against your threat model: identifying where your network controls are weakest and most exposed.

03

Harden

We implement controls directly (firewall rules, segmentation, monitoring) not just a list of recommendations.

04

Validate

Post-implementation testing to confirm controls are working as designed and not creating operational issues.

Not sure where your network is exposed?

A network assessment will tell you. We map your topology, test your controls, and give you a prioritised remediation plan, not a generic report.

Frequently asked questions

What does Netru's Network Security service include?

Netru scopes Network Security 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 Network Security 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 Network Security?

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.
