Why it matters

The business case for data security

Data is your most valuable and most targeted asset. Most organisations can't say where their sensitive data lives, who can access it, or whether it's adequately protected.

  • GDPR, NIS2, DORA & the EU AI Act create layered obligations to protect and govern data
  • AI models trained on unclassified data can expose sensitive information
  • Post-quantum migration timelines are live — early preparation is a strategic advantage

What we do

How we help

From discovering and classifying sensitive data through to cryptographic controls, key management and a post-quantum readiness roadmap.

01

Data Discovery & Classification

Identify and classify PII, PCI, IP and health data across cloud storage, databases, SaaS, email and file shares — with automated tagging.

02

Data Loss Prevention

DLP across email, Google Workspace, Microsoft 365, endpoints and web — preventing exfiltration and accidental exposure.

03

Cryptography, PKI & Key Management

Encryption strategy, PKI design, certificate lifecycle management and Thales HSM integration — protected and auditable.

04

Post-Quantum & AI Data Security

PQC readiness and migration roadmap aligned to NIST FIPS 203/204/205, plus protection of AI training data and pipelines.

Pain points we address

Sound familiar?

01

No idea where sensitive data lives

PII spreads across cloud, SaaS, shared drives and databases with no systematic inventory.

02

AI models expose protected data

Models trained on internal data can memorise and regurgitate sensitive content.

03

Inconsistent encryption, mismanaged keys

Keys stored in the wrong places, unrotated for years, or managed in spreadsheets.

04

DLP absent or monitor-only

Data leaves via email, personal storage and APIs without anyone noticing.

05

The post-quantum threat is already in motion

Harvest-now-decrypt-later attacks are collecting encrypted data today.
