The two, side by side

SOC 2ISO 27001
What it isAn auditor's report on your controlsA certification of your security management system
Who asks for itOften US business customersOften international and enterprise customers
ScopeControls for the criteria you choose, such as security and availabilityA management system covering policies, risk and controls
Issued byAn independent auditorAn independent certification body

What preparation involves

  • A security review of your cloud accounts, access rules and code
  • Written policies: access, change management, incident response, backups
  • Single sign-on and two-factor login, with least-privilege access
  • Logging and monitoring, so you can show what happened and when
  • Security checks in your delivery pipeline
  • Evidence: records that the controls were really in place over time

A sensible order of work

  • Start with a review, and fix the cheap, high-impact gaps first
  • Write only the policies you will follow
  • Switch on logging and evidence collection early, because auditors want a track record
  • Run a penetration test, if the scope or your customers ask for one
  • Then book the audit

We prepare you and support you through the audit. We do not issue the report or certificate; an independent auditor does.

Frequently asked questions

Which should we get first?

How long does it take?

It depends on how far you are today. A review gives you a realistic plan before you commit.

Do we need a penetration test?

Often it is expected, or asked for by customers. We offer VAPT testing.

Can you issue the certificate?

No. An independent auditor or certification body does. We prepare you for it.
