Frequently asked questions

We’re a small business — are we really a target?

Yes. Most attacks are automated and indiscriminate, which is why even small organisations need solid basics. We make strong security affordable and practical.

Do you help with compliance?

We help you meet UK GDPR and common standards through appropriate technical and organisational controls and documentation.
