SOC 2 vs ISO 27001

By Murty Nisthala, CISA, CISSP, CCSP. Reviewed by Girija Togarati, ISO 27001 Lead Auditor.

SOC 2 and ISO 27001 both prove strong information security, but they differ. SOC 2 is an attestation report under AICPA criteria. ISO 27001 is a certifiable international standard with a formal certificate.

How they differ

SOC 2 produces a report you share under non disclosure, often requested by United States clients. ISO 27001 issues a globally recognised certificate valid for three years. Their underlying controls overlap heavily.

Which to choose

If your clients are mostly in the United States, SOC 2 may come first. If your buyers are global or European, ISO 27001 is usually the stronger choice. Many firms do both.

Do them together

Because the controls overlap, Univate can run SOC 2 and ISO 27001 with one control set, saving time and cost.
