ISO 27001 vs SOC 2: What Each One Actually Proves About a Vendor


Ask any security or procurement team what they look for before signing off on a new vendor, and you'll hear the same shortlist: ISO 27001, SOC 2 Type II, and sometimes GDPR or HIPAA alignment depending on the industry. It's easy to write these off as acronyms that live in a footer somewhere. In reality, they're the closest thing the industry has to a shared answer to one question: how do we know this platform will protect our data?

The stakes behind that question keep rising. IBM's 2026 Cost of a Data Breach report puts the average breach at a record $4.99 million, up 12% in a year, and organizations took an average of 247 days to identify and contain one. At the same time, the number of valid ISO 27001 certificates worldwide roughly doubled in a single year.

$4.99M average cost of a data breach in 2026, 247 days to identify and contain it, 96,709 valid ISO/IEC 27001 certificates worldwide, 93 Annex A controls

Here's a closer look at what these two standards mean, why they're worth caring about beyond the audit itself, and how that thinking shows up in the way DeployByDesign (DBD) is built.


What ISO 27001 Covers

ISO/IEC 27001 is published jointly by the International Organization for Standardization and the International Electrotechnical Commission, and it's the standard most people mean when they talk about "ISO compliance" for information security. What it certifies isn't a product or a specific set of tools. It's an Information Security Management System (ISMS): the organizational machinery a company uses to identify, manage, and continuously reduce information security risk.

Adoption is accelerating. The ISO Survey 2024 counted 96,709 valid ISO/IEC 27001 certificates covering 179,877 sites worldwide, up from 47,291 certificates a year earlier. The standard is also freshly revised: certificates issued against the older 2013 version stopped being valid on October 31, 2025, so every current certificate is to the 2022 edition.

Getting there isn't a one-time exercise. Certification generally works through a few stages:

  • Risk assessment first. Before any controls are put in place, the organization has to systematically catalog where its real risks are, across infrastructure, third-party vendors, employee access, physical security, and data handling. ISO 27001 is deliberately risk-based rather than prescriptive, so the controls a company implements are shaped by its own risk profile, not a generic checklist.
  • Controls mapped to Annex A. The standard ships with a reference set of controls (93 in the current 2022 revision, grouped into organizational, people, physical, and technological themes) covering areas like access control, cryptography, supplier relationships, incident management, and business continuity. Organizations select and implement the ones their risk assessment shows are relevant, and document why the rest don't apply.
  • A functioning management system, not just documentation. The "MS" in ISMS matters. Auditors aren't only checking whether policies exist on paper. They're checking for a real operating rhythm: defined ownership, regular internal audits, management reviews, and a documented process for handling nonconformities when something doesn't work as intended.
  • An external certification audit in two stages. Stage 1 reviews documentation and readiness. Stage 2 is a deeper audit of whether those controls are working as designed.
  • Ongoing surveillance. A certificate is valid for three years, but ISO 27001 isn't a "certify and forget" standard. Annual surveillance audits check that the ISMS is still active and maintained, with full recertification at the end of the cycle.

The distinction worth remembering. ISO 27001 certifies a system for managing risk continuously, not a fixed state of security at a single moment in time.


What SOC 2 Covers

SOC 2 comes from a different tradition. It was developed by the American Institute of Certified Public Accountants (AICPA), and strictly speaking it isn't a certification at all. It's an attestation, delivered as a formal report after an audit by a licensed CPA firm. That trips a lot of people up, and it matters: no governing body issues a badge the way one does for ISO. You get a report, and the report's credibility rests on the reputation of the auditor who signed it.

SOC 2 evaluates an organization against five Trust Services Criteria. Not every company puts all five in scope. Security is mandatory, and the rest are chosen based on relevance:

  • Security: the baseline criterion, covering protection against unauthorized access, whether through external attacks or internal misuse.
  • Availability: whether systems are up and accessible in line with what's been committed to customers.
  • Processing Integrity: whether data processing is complete, accurate, timely, and authorized.
  • Confidentiality: whether information designated as confidential is protected accordingly. This is distinct from personal data specifically.
  • Privacy: how personal information is collected, used, retained, and disposed of, measured against the organization's own stated privacy practices.

There are two report types, and the difference between them is significant:

  • Type I evaluates whether an organization's controls are suitably designed as of a specific date. It's essentially a snapshot.
  • Type II evaluates whether those same controls operated effectively over an observation window, typically somewhere between three and twelve months.

Type II is considerably harder to earn. It doesn't ask "do you have a policy that says you do this?" It asks an auditor to sample real evidence across months and confirm the policy was actually followed. That's why Type II reports carry more weight with enterprise buyers: they're evidence of sustained behavior, not documented intention.

Mature providers keep that evidence continuous. AWS, for example, publishes its SOC 2 and SOC 3 reports twice a year, each covering the previous 12 months, so there's never a gap in the observation window.


The Two Side by Side

ISO 27001 SOC 2
Issued by ISO / IEC, via accredited certification bodies AICPA framework, audited by licensed CPA firms
What you receive A certificate An attestation report
What's assessed The management system for handling information security risk Controls against the Trust Services Criteria in scope
Scope setting Risk assessment drives which Annex A controls apply Security is mandatory; other criteria are chosen
Time dimension 3-year cycle with annual surveillance audits Type I is a point in time; Type II covers an observation window
Most common with Global and European buyers North American buyers

In practice the two overlap heavily. Many of the same controls, such as access reviews, encryption, logging, and incident response, satisfy both, which is why organizations often pursue them together.


Why Compliance Matters Beyond the Audit

It's tempting to treat compliance as something companies chase only because enterprise deals require it. That's part of the picture, but it misses the bigger point.

The controls are the point, not the paperwork. Access reviews, encryption, and incident response plans aren't audit theater. They're the same practices that stop a breach from happening in the first place, and that shorten the 247 days it takes the average organization to find and contain one.

Regulated data raises the price of getting it wrong. Healthcare has been the costliest industry for data breaches for 13 consecutive years, according to IBM. For teams working with patient or insurance data, strong controls aren't optional.

Independent verification means something. Any company can say it takes security seriously. A SOC 2 report or an ISO certificate means someone outside the company checked that claim and put their name on it.

It keeps security from going stale. Neither framework is a one-time achievement, so ongoing audits force organizations to keep pace with a changing threat landscape instead of freezing their security posture in time.

It removes friction between businesses. Instead of every customer running a custom vendor security review from scratch, these frameworks give both sides a common starting point. That usually means faster deals and less back-and-forth.


How DBD Puts This into Practice

DeployByDesign's security posture isn't layered on top of the platform after the fact. It's tied directly to how the platform is designed to be used day to day.

DBD by the numbers: 12 months of audit logs, AES-256 encryption at rest, no public IPs on workspaces, 72-hour breach notification

A few examples of what that looks like:

  • Access is structured, not improvised. Every workspace on DBD sits behind role-based access control, an organizational hierarchy, and single sign-on. Who can see what is a deliberate setting, not something managed ad hoc across spreadsheets and Slack messages.
  • Activity is logged and retained. DBD keeps 12 months of audit logs for workspace activity: starts and stops, file access, and user invites. If a customer or regulator needs to know who accessed what and when, that history already exists instead of having to be reconstructed after the fact.
  • Data is encrypted and workspaces stay private. Each user's file storage is encrypted at rest with AES-256, with keys managed through AWS KMS. Traffic to the platform is encrypted with TLS, and JupyterLab, RStudio, and VS Code sessions run over encrypted connections. Workspaces run on private subnets with no public IP addresses.
  • Sensitive data has a home built for it. For teams working with healthcare, insurance, or other regulated data, DBD's data handling is designed with HIPAA and GDPR expectations in mind from the start rather than retrofitted later.
  • Shared and cross-account work doesn't bypass governance. Features like shared workspaces and cross-account roles across AWS and GCP environments still route access through the same governed permission model.
  • Compliance isn't one team's job. Because access control, encryption, and logging are built into the platform itself, every team using DBD inherits that foundation instead of having to build it themselves.

Standing on an Audited Foundation

That foundation is reinforced by the infrastructure underneath it. DBD runs on AWS, which maintains its own independently audited attestations and certifications, including SOC 1, SOC 2, ISO 27001, ISO 27017, ISO 27018, and CSA STAR. Physical data-centre security, encryption tooling, and multi-availability-zone resilience are handled at that layer.

You don't have to take that on trust. The evidence is published, and anyone can check it:

AWS ISO/IEC 27001 certificate AWS SOC reports
Standard ISO/IEC 27001:2022 AICPA Trust Services Criteria: Security, Availability, Confidentiality, Privacy
Issued by EY CertifyPoint, accredited by the Dutch Accreditation Council Ernst & Young LLP
Reference Certificate no. 2013-009, held continuously since November 18, 2010 Latest SOC 3 covers April 1, 2025 to March 31, 2026
Validity Issued November 25, 2025; expires November 30, 2028, with annual surveillance audits SOC 2 and SOC 3 reissued twice a year, each covering the prior 12 months
Where to get it Official certificate (PDF) SOC 3 report (PDF, public); SOC 2 via AWS Artifact under NDA

It's worth being precise about what that means. Those reports and certificates cover AWS's infrastructure, not DBD's platform. What they do is let DBD focus its own security work on the layer that sits above the infrastructure and is DBD's responsibility: identity, access, and data governance. This is the shared responsibility model working as intended.

The point isn't to collect certifications for their own sake. The discipline those certifications are designed to verify (careful access control, consistent monitoring, real accountability for data) is the same discipline DBD builds into the platform whether or not an audit is happening that quarter.


Bottom Line

ISO 27001 and SOC 2 exist to answer a question no vendor can credibly answer about itself: can this company actually be trusted with sensitive data, as verified by someone with no reason to be generous about it? For any team choosing infrastructure to build on, especially in regulated spaces, that's not a footnote. It's often the most important decision criterion in the room.

For DeployByDesign, the goal has never been just to pass an audit. It's to make sure the platform is already built the right way before an audit ever asks.
