SOC 2 attestation in London at a glance
Software and fintech companies in London that sell to American enterprises meet the same request early in the deal: share your SOC 2 report. London's concentration of City clients and cloud suppliers means many firms need it alongside, not instead of, ISO 27001. SOC 2 is an attestation, not a certification: an independent licensed firm reports on controls against the AICPA trust services criteria, with Type 1 covering design and Type 2 operation over a period. Sterling's London office prepares the controls, with Effivity and Sterling Academy included with the engagement; the attestation report is issued by an independent licensed firm. National law, regulators and accreditation detail sit on the United Kingdom page rather than here.

SOC 2 in London: questions clients ask
Do London firms need SOC 2 if they hold ISO 27001?
Often they need both, because the two answer different buyers. ISO 27001 is a certificate; SOC 2 is a report from an independent licensed firm, preferred by many American buyers. Many London suppliers build one control set and map it to both, so the extra effort is smaller than starting again.
Which SOC 2 report suits a young London company?
A Type 1 report is the usual first step because it covers design at a point in time, and it can unlock early deals. A Type 2 report follows, showing controls working over an observation period. Buyers often state which they want, so check the request before choosing.
