ISO 27001 vs SOC 2: What Regulated Businesses Need to Know
If you procure security or IT services in a regulated industry, the ISO 27001 vs SOC 2 question comes up early — usually in a vendor questionnaire, and usually with a deadline attached. Both frameworks tell you something real about how a vendor handles your data and your sites, but they answer different questions. Knowing which one matters for your audit saves weeks of back-and-forth.
ISO 27001 vs SOC 2: the core difference
ISO 27001 is a certification. An accredited body audits your information security management system (ISMS) against a defined standard and issues a certificate valid for three years, with annual surveillance audits. It is prescriptive: there is a control set, and you either operate it or you don't.
SOC 2 is an attestation report, issued by a CPA firm against the AICPA Trust Services Criteria. There is no certificate and no pass mark. Instead you get a report describing the controls and the auditor's opinion. Type I tests design at a point in time; Type II tests operating effectiveness over a period, usually 3 to 12 months. Type II is what enterprise buyers actually want.
Which one your buyers will ask for
Geography and sector drive this more than anything. Indian, European and Middle East enterprises tend to ask for ISO 27001 because it maps cleanly onto tender documentation. US-headquartered companies — and most fintech and SaaS procurement teams — ask for SOC 2 Type II. Multinationals with an India delivery footprint routinely ask for both, which is why Foxnet maintains ISO 27001, SOC 2 Type II and ISO 45001 rather than choosing between them.
One practical note for physical security projects: neither framework certifies your cameras or door controllers. What they cover is how the integrator handles credentials, video data, remote access and change management. If a vendor points at a manufacturer's certificate instead of their own, that is worth a follow-up question.
What auditors actually look for on site
In our experience across 100-plus deployments, evidence requests cluster in a few places. Who holds administrative access to the video management system and access control platform, and how is that reviewed. Whether footage retention matches your stated policy. How technician access to client sites is provisioned and revoked. Whether the network carrying security traffic is segmented from general corporate traffic — a point where IT infrastructure design and compliance meet directly.
Getting those four things documented before an audit window opens is usually the difference between a clean report and a list of exceptions. It also tends to expose gaps in access control governance that were invisible day to day.
If you are preparing for an ISO 27001 certification cycle or a SOC 2 Type II window and want your surveillance, access control and network layers to hold up under evidence review, we are happy to walk through your current setup. Book a demo and bring your auditor's request list.
