How to implement network segmentation in the cloud

2026-07-116 min readZryos

Security is not a product you buy — it's a discipline you practice. The best security programs are boring: consistent controls, documented decisions, and regular audits. This article covers network segmentation cloud with the security practices we implement for clients who need to pass audits and protect real data.

At Zryos, we help clients achieve SOC2, ISO 27001, and PCI DSS compliance. The pattern we see with aws security groups is that most security issues come from fundamentals that were skipped: IAM policies that are too broad, secrets stored in code, and no network segmentation. Fixing vpc segmentation starts with threat modelling — understanding what you're protecting and from whom — before choosing tools.

If you're preparing for a security audit or want to improve your security posture, we offer a security assessment that maps your current state against common frameworks. We'll identify the gaps, prioritise them by risk, and help you close them. Security doesn't have to be overwhelming — it just has to be systematic. Book a call to get started.
