IDENTITY-driven SECURITY ADVISORY — Greece & Europe
Identity is your primary control plane.
Most organisations do not govern it properly.
We help you fix that.
Nimbus Cyber advises mid-size and large organization's on Identity Governance, Security prioritization and Microsoft-centric security architecture — before the incident, the audit, or the board question that exposes what was never in place.
Who we work with
We work with CIOs, IT Directors and Security Managers in organisations of 100–500+ employees where security has outgrown its structure.
Typically:
Microsoft-heavy environments
Under NIS2 or ISO 27001 pressure
Without a dedicated CISO
With identity and access complexity that has grown faster than it has been governed
Not a fit:
If you are looking for generic security support, broad coverage across all domains, or low-cost execution, we are not the right partner.
When clients call us
Clients typically call us when:
An audit is approaching and the access model cannot withstand scrutiny
Identity and access decisions are fragmented across teams and systems
A security programme exists, but no one can clearly explain priorities or ownership
Microsoft 365 capabilities are expanding without proper Governance
They need a senior security voice, without hiring one full-time
How an engagement works
Every engagement begins with a focused diagnostic conversation — no pitch, no generic presentation. We identify the specific governance gap, compliance pressure or architectural risk your organisation is facing. From there, engagements are scoped and bounded: a fixed assessment, an advisory retainer, or a phased architecture programme. You know what you are buying and what it delivers before work begins.
The perimeter is gone.
Identity is the new battlefield.
Over 80% of breaches today begin with compromised identity — a stolen credential, an over-privileged service account, a stale access right that should have been revoked six months ago. The attacker didn't break in. They logged in.
In a cloud-first world, the security perimeter no longer exists. Every user, every device, every application, every API token is a potential entry point. Human identities are targeted. Non-human identities — machine accounts, service principals, CI/CD pipelines — are exploited. AI agents — autonomous systems acting on behalf of your organisation with their own identities and permissions — are the fastest emerging attack surface of 2026. Human, non-human and AI agent identities. All three need governance. Most organisations are governing one.
At Nimbus Cyber, we build the identity and security foundations that reduce your risk exposure, improve your resilience and ensure that when threats materialise — and they will — your architecture limits the damage.

What we do — and why it matters to your business
Four core specialisms. All built around one conviction — identity is the primary control plane of modern security.
Identity Governance & Access
Most identity governance programmes cover human identities and stop there. That is a problem — because non-human identities now outnumber human ones by 40 to 1. For every employee, contractor or partner with access to your environment, there are 40 service accounts, managed identities, API credentials and automation tokens that are almost universally ungoverned, unreviewed and permanently credentialed. Stale human accounts are dangerous. Forty times as many ungoverned non-human identities is a crisis. We govern both — designing and implementing IGA frameworks that automate the full identity lifecycle across your entire estate so every access right is justified, documented and audit-ready.
Cloud & AI Security
Your organisation is running on cloud infrastructure and AI tools that were built for speed, not security. Azure subscriptions with accumulated misconfigurations. Microsoft 365 environments with years of ungoverned permissions. AI tools — Copilot, custom GPTs, MCP servers — deployed on top of broken access models that surface sensitive data to anyone who knows how to ask. We assess, harden and govern your full cloud and AI security posture — from infrastructure to AI layer — aligned to your industry's regulatory requirements.
Fractional CISO & Regulatory Advisory
Every organisation needs senior security leadership — not every organisation can justify a full-time CISO. We provide ongoing advisory covering security strategy, NIS2 and DORA compliance readiness, ISO 27001 implementation support and vendor risk governance.
Zero Trust Architecture
Zero Trust is not a product. It is an architectural decision. We design identity-centric Zero Trust models that eliminate implicit trust from your environment — starting with identity, not the network. Every user, every device, every request verified explicitly.
