Cloud Security

Control the configuration, the identities and the workloads — in that order.

What this is

Cloud security is mostly a configuration and identity problem. Breaches in cloud estates rarely begin with an exploited platform; they begin with a storage bucket left open, a role granted more than it needed, or a key committed to a repository. This capability covers posture management, entitlements, workload protection and the audit trail that makes any of it provable.

The distinction that matters is between finding misconfiguration and preventing it. Scanning production tells you what is already wrong. Scanning infrastructure-as-code in the pipeline stops it being deployed. We build toward the second while the first keeps the lights on.

When you need it

If more than one of these is true, this is usually the right place to start.

  • Multiple cloud accounts or subscriptions created over time, with no consistent baseline between them.
  • Identity and access management grown by exception, where nobody can say what a given role can actually reach.
  • A move to containers or serverless that the existing security tooling does not see inside.
  • A regulator, customer or insurer asking for evidence of cloud controls that would take weeks to assemble by hand.

What the scope covers

  • Posture baseline across accounts: a defined standard, the current deviation from it, and which deviations are accepted.
  • Cloud infrastructure entitlement management: what each identity, human and machine, can actually do — as opposed to what it was intended to do.
  • Workload protection for virtual machines, containers and serverless functions, including image scanning and runtime policy.
  • Infrastructure-as-code scanning in the pipeline, so a misconfiguration fails a build rather than reaching production.
  • Audit logging and drift detection, retained and forwarded so the trail survives the account that produced it.

What you receive

DeliverableWhat it contains
Posture baselineThe standard applied, per-account deviation, and a remediation order driven by exploitability rather than count.
Entitlement reviewEffective permissions per identity, over-privilege highlighted, and a least-privilege target with a path to it.
Pipeline controlsIaC and image scanning wired into your CI, with the policy that decides what fails a build and who can override it.
Evidence packControl-to-requirement mapping and where each piece of evidence is produced — so the next audit is a query, not a project.

Reference architecture

A reference, not a template. Your estate decides which parts apply and in what order they arrive.

How success is measured

Targets are agreed with you before the work starts, and reported against for its duration.

  • Deviation from the agreed baseline, by account, tracked over time rather than at a point.
  • Share of infrastructure changes that pass through pipeline scanning before deployment.
  • Number of identities holding permissions they have not used in the review period.

Questions we are asked

  • Is the cloud provider not responsible for security?

    For the platform, yes. Under every major provider's shared responsibility model, configuration, identity and data are yours. The provider will keep the storage service running; it will not stop you making a bucket public.

  • We are on more than one cloud. Does that change things?

    It changes tooling and terminology, not the principles. The main risk in a multi-cloud estate is a baseline that exists properly in one provider and vestigially in the others, so the standard is defined once and then expressed per provider.

  • Do we need a dedicated cloud security product?

    Native tooling covers a useful amount, particularly in a single-provider estate, and it is worth exhausting before buying. A dedicated platform earns its cost when you need one view across providers or capability the native tools lack.

  • What about containers and Kubernetes?

    They are in scope. Image scanning before deployment, admission control at the cluster boundary, and runtime policy inside it — with the caveat that runtime enforcement needs tuning or it will be turned off within a month.

  • How does this relate to compliance work?

    The controls are the same; the difference is evidence. Building the evidence trail while the control is implemented costs very little. Reconstructing it a year later for an audit costs a great deal, which is why the evidence pack is a deliverable rather than an afterthought.

  • Can you fix what a scan already found?

    Yes, and the sequencing matters more than the fixing. A first scan of an untended estate produces hundreds of findings, most of which do not matter. We order remediation by what is actually reachable and exploitable, not by the tool's severity column.

    The full domain, and the other capabilities within it.

  • Identity & Access Management

    Single sign-on, multi-factor authentication, privileged access and joiner-mover-leaver — built so access is granted deliberately and removed automatically.

  • Data Protection

    Classification, encryption, key management and data loss prevention — starting from where your data actually is, not where the policy says it should be.
