Build security that stands up in the real world.
From cloud architecture to board reporting - we make security provable, scalable, and easy to run.
Services
Microsoft 365 Security
Most organisations are under-utilising the security capabilities already included in their M365 licence. We configure, tune, and harden your Microsoft 365 environment - identity, email protection, DLP, and Conditional Access - so it works as a security platform, not just a productivity suite.
vCISO & Security Leadership
Executive security leadership delivered through repeatable, secure-by-design programmes. We define risk-led roadmaps, automate reporting and assurance where possible, and translate technical controls into clear board-level decisions - tailored to your maturity and industry.
Cloud Security & Architecture
Secure-by-design cloud platforms built using automation and repeatable patterns. We embed identity, governance, logging, and guardrails into the platform itself, creating environments that are safer by default and easier to operate at scale.
GRC & Audit Readiness
Audit readiness built into daily operations through secure-by-design controls and automated, repeatable evidence collection. We align your programme to standards such as ISO 27001, SOC 2 and PCI DSS, reducing audit effort while increasing confidence.
Approach
1) Discover
Understand your environment, risks, and constraints. Build a crisp, prioritised view of what matters.
“What are the top risks, what’s the evidence, and what do we do next?”
2) Design
Architect controls that fit your delivery model and budget - with clear ownership and measurable outputs.
Guardrails, not gatekeeping.
3) Deliver
Implement, tune, document, and hand over. Everything is evidence-led and audit-friendly.
Secure changes you can prove.
4) Improve
Operate, review, and continuously strengthen security posture using KPIs and incident learnings.
Security to help not hinder business operations.
About
Who we are
Blue Stag Cyber is a UK-based security consultancy built around the idea that good security should be explainable, measurable, and practical. We work with growing businesses and enterprise teams that need senior security expertise without the overhead of a full-time hire - whether that's building a programme from scratch, passing an audit, or hardening a cloud platform.
We don't do vague recommendations. Every engagement ends with clear ownership, documented evidence, and security that the business can actually run.

We keep engagements focused and outcomes measurable.
