IDENTITY-driven SECURITY ADVISORY — Greece & Europe
Control access.
Reduce identity risk.
Be ready to demonstrate it.
Know who and what can access your critical systems, where the risks are and what to fix first.
Nimbus Cyber helps you turn human and non-human identity risks into clear priorities, accountable ownership and evidence that supports audit and leadership decisions.
An audit approaching. Security priorities unclear. Where do you start?
When access decisions are scattered across teams and systems, answering an auditor or setting security priorities becomes difficult. You need clear answers:
-
Who has privileged access—and is it still justified?
-
Which applications, service accounts and AI agents can access critical systems—and who owns them?
-
Can you demonstrate that access is approved, reviewed and removed when no longer needed?
-
What should you fix first, and who will take responsibility?
From your first conversation to practical next steps.
Step 1 — Discuss your situation
Tell us what is driving the need: an approaching audit, uncertainty about access or a gap in security leadership. We clarify the questions you need answered.
Step 2 — Agree a focused review
Together, we define the systems, identity types and controls to examine, along with the deliverables, timing and input needed from your team.
Step 3 — Make informed decisions
We walk you through the findings and recommended priorities, so your team can agree ownership and next steps. Where ongoing guidance is needed, vCISO support can help maintain direction and track progress.
Understand your identity risks. Leave with a clear action plan.
An Identity Security Review gives you a focused assessment of human and non-human access across agreed systems—so you can prioritise improvements and prepare for audit or leadership scrutiny.
-
Your key access risks: where permissions are excessive, ownership is unclear or access controls need attention.
-
Prioritised next steps: what to address first, why it matters and what can follow.
-
Clear responsibilities: proposed action owners to agree with your team.
-
An evidence plan: what to document and retain to demonstrate that access controls are working.
We agree the scope and deliverables before work begins, so you know what the review covers and what you will receive.
Every identity needs an owner. Every access right needs a reason.
Employees and contractors need appropriate access to do their jobs. Applications, service accounts and AI agents also access your systems and data—sometimes with permissions that remain long after their original purpose has changed.
When ownership is unclear or permissions go unreviewed, it becomes harder to control risk and explain access decisions.
Nimbus Cyber helps you establish who owns each identity, what access it needs and when that access should change or end. The outcome: fewer unnecessary privileges, clearer accountability and evidence you can use when decisions come under scrutiny.

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.
