Network Security
The network is still where lateral movement happens, even in a cloud-first, identity-centric world. Segmentation and monitoring determine whether one compromised device stays contained or becomes an incident.
Delivered from our base in Utrecht, available to organisations across the Netherlands.
The problem
Many networks are flat by accumulation rather than by design. Segmentation that made sense five years ago hasn't kept pace with new systems, new offices, and new integrations. The result is a network where a single compromised device can often reach far more than it should be able to.
Business impact
Lateral movement is how a single compromised laptop becomes a company-wide incident. Proper segmentation doesn't prevent every initial compromise, but it determines whether that compromise stays contained or spreads.
From architecture review to day-to-day monitoring.
Network architecture review
Assessing how your network is actually segmented, versus how the diagram says it's segmented.
Segmentation & microsegmentation
Limiting lateral movement so a single compromised host doesn't become a compromised network.
Firewall & IDS/IPS
Rule-set review and intrusion detection tuned to your actual traffic patterns, not vendor defaults.
ZTNA & remote access
Zero Trust network access replacing flat VPN access with per-application, per-session verification.
DNS security
DNS filtering and monitoring: one of the most consistent early signals of compromise.
Network monitoring
Visibility into what's actually traversing your network, not just what's allowed to.
How this engagement runs
Assess
Understand the current state, real risk, and what's actually driving the need for this work.
Architect
Design the controls and approach that fit your environment, not a generic template.
Implement
Deploy and integrate the work: configuration, code, or process, whichever the engagement calls for.
Validate
Test that it actually holds up, rather than assuming it does because it's been deployed.
Improve
Feed findings back in as your environment and the threat landscape change.
Who this is for
- Organisations with on-premises or hybrid infrastructure and no recent network architecture review
- Companies still relying on flat VPN access for remote work
- Businesses that have grown network complexity faster than their segmentation strategy
What you get
- A network architecture and segmentation review
- Firewall and IDS/IPS rule-set assessment
- A ZTNA migration plan where flat VPN access is currently in use
- DNS security and monitoring recommendations
Frequently asked questions
Is network security still relevant if most of our infrastructure is in the cloud?
Yes. Lateral movement within a cloud VPC follows the same principles as on-premises segmentation, and most organisations still run a meaningful amount of on-premises or hybrid infrastructure where flat, unsegmented networks remain a common finding.
What's the difference between a VPN and ZTNA?
A traditional VPN grants broad network access once connected. Zero Trust Network Access verifies identity, device and context per application and per session, so a compromised VPN credential doesn't hand over the whole network.
