Data Security & Encryption Audits

Verify how your data is protected, where keys live, and who can access what—then close the gaps with a clear, prioritised plan.

Outcomes

What you’ll achieve

Clarity on sensitive data

Where it’s stored, who touches it, and how it moves—inside your cloud and between vendors.

Encryption that holds up

Data-at-rest and in-transit verified; ciphers, key lengths, rotation and escrow assessed.

Keys under control

KMS/HSM setup reviewed; access restrictions, rotation, split knowledge and auditability.

Least-privilege access

IAM roles, service accounts and secrets use hardened; break-glass and logging covered.

Backups you can recover

Immutable copies, RPO/RTO checks, restore drills and scope against ransomware risk.

Evidence for stakeholders

Findings mapped to GDPR Articles & common frameworks (ISO 27001/2, NIST CSF).

Scope

What’s included

A focused review of encryption, key management, access controls and backups—delivered as a clear risk register and engineering-ready backlog.

Data flow & classification review (PII, special categories, secrets)

At-rest encryption review (DB, object storage, disks, snapshots)

In-transit encryption review (TLS policies, certs, mTLS options)

Key management assessment (KMS/HSM, rotation, access, audit logs)

Access control & secrets (IAM, RBAC/ABAC, vaults, rotation policies)

Backup & DR posture (immutability, isolation, restore tests)

Vendor & SaaS storage settings (geo, export, retention, logs)

Findings report + prioritised remediation backlog

Example encryption audit report and remediation plan

Example output: risk register, remediation backlog and evidence you can share with auditors or customers.

Method

How it works

1) Discovery
Review diagrams, configs and access; walk through data flows and threat model.
2) Validate
Inspect cloud/IAM settings, KMS/HSM, backups, TLS and vendor controls.
3) Recommend
Gap analysis vs policy and standards; produce a prioritised fix plan.
4) Harden
Optionally assist changes, validate the new posture, and package evidence.

If you want implementation help, we can convert findings into a short hardening sprint with clear owners, change sequencing and re-validation.

FAQ

Questions, answered

Will this require production access?

Read-only access to configs and logs is typically enough. Where needed, we schedule supervised sessions.

Do you break anything?

No. Audit steps are non-disruptive, and changes are proposed and reviewed before implementation.

Can you help implement fixes?

Yes—many clients opt for a short hardening sprint to close high-impact gaps quickly.
