Writer’s trust architecture sets a new benchmark for enterprise AI security

Writer advances what enterprise-ready AI must look like with its announcement of ISO/IEC 27001, 27701, and 42001 certifications—alongside renewed SOC 2 Type II,  Health Insurance Portability and Accountability Act (HIPAA), and payment card industry (PCI) compliance. For buyers navigating increasing pressure from risk, compliance, and regulatory teams, this suite of credentials brings substance to the often-hollow promise of ‘secure’ AI.

The HFS Pulse Survey (H1, 2025) reveals how important security is to today’s enterprise leaders—ranking as a top three concern (see Exhibit 1) among external factors constraining your ability to achieve your goals. It is the only one of the top three that firms can take some control over.

Certifications add layers of defensibility for enterprise buyers

Each certification adds a layer of defensibility for enterprise buyers:

• ISO/IEC 27001 addresses information security management, validating the strength and maturity of Writer’s internal security infrastructure.
• ISO/IEC 27701 extends that foundation to global privacy laws such as the General Data Protection Regulation (GDPR), Health Insurance Portability and Accountability Act (HIPAA), and California Consumer Privacy Act (CCPA), offering peace of mind in jurisdictions where data handling is under legal scrutiny.
• ISO/IEC 42001, the newest of the three, reflects structured oversight of AI governance, accountability, and lifecycle risk—critical in light of the EU AI Act and other emerging frameworks.

This supports an AI architecture where safety and oversight are embedded into the product’s operational fabric. For enterprise IT, legal, and compliance teams, this matters far more than generic promises about trust.

Industry-specific assurances are increasingly non-negotiable

The additional certifications—SOC 2 Type II, HIPAA, and Payment Card Industry Data Security Standard (PCI DSS)—expand Writer’s applicability into healthcare, finance, and other regulated sectors where audit trails and data handling protocols are non-negotiable.

These are threshold requirements for vendors to support mission-critical deployments involving sensitive data. Writer’s ability to meet these criteria positions it strongly in environments where many general-purpose LLM providers are still figuring out how to retrofit security into otherwise open architectures.

A lead for now—but enterprise scrutiny will shape what’s next

Writer’s full-stack model, combining proprietary LLMs, orchestration layers, and security infrastructure, provides consistency and control that stands out in a market fragmented by APIs and third-party integrations. The trust story is reinforced by practical features such as role-based access, agent supervision tools, and explainability interfaces.

And while Writer’s move to the ‘triple-ISO’ stack is commendable, their position is unlikely to be unique for long—and neither does it cover the whole gamut of multi-national business need.

The triple-ISO stack is one part of a long list of certifications firms and government agencies must now demand

A whole flurry of certifications is increasingly required by leaders in specific domains and/or who are operating in truly global businesses—among them:

• FedRAMP High / DoD IL-5: Azure OpenAI, Google Agentspace and AWS Bedrock all now have High authorisations for select models—a requirement for public sector and defence contracts.
• ISO 22301 (Business Continuity) & ISO 20000-1 (Service Mgmt.): Both covered by AWS and Microsoft; key for regulated financial-services in rapid recovery discussions.
• CSA STAR Level 2/3: Hyperscalers list STAR certifications, giving extra transparency around cloud controls.
• HITRUST CSF: Cohere advertises HITRUST-ready hosting, useful for US healthcare; Writer’s HIPAA is solid but HITRUST goes deeper.
• Regional attestations: IRAP (Australia), TISAX v5 (for the global automotive industry), ENS High (Spain), are already in Azure/GCP compliance catalogs.
• Transparent model risk disclosures: Anthropic and Google publish model cards aligned to ISO 42001 risk clauses.

The credentials moat is narrowing fast

Hyperscalers are leap-frogging with FedRAMP High (on the demand of US public sector contracts). And while pure-play model vendors (OpenAI, Cohere) still trail on privacy (ISO 27701) and AI-governance (ISO 42001), they rely on their infrastructure partners’ attestations to deliver trust.

Systems integrators hold core ISO 27001/27701 but use advisory services rather than certifying their nascent LLM platforms. In short, Writer leads on an integrated, product-level trust architecture, but the credential moat is narrowing fast.

The next procurement cycle will judge depth more than certificate count

What remains to be seen is how many can operationalise these standards at every layer of their architecture. The next procurement cycle will judge depth (continuous controls, public–sector readiness, audit self-service) more than certificate count. For enterprises, the emphasis should now shift to evaluating how trust mechanisms are maintained, monitored, and made visible—not just which ones are claimed.

Buyers also need to reflect on their frameworks. Are your procurement and risk teams equipped to assess modern AI governance claims? Do your internal policies expect the same level of clarity and structure from all vendors?

The Bottom Line: The next wave of enterprise AI will move forward on trust that can be proven.

Writer has moved quickly to build a robust trust foundation that reflects where enterprise AI is heading in terms of compliance and operational maturity. This gives enterprise leaders a credible reference point for evaluating other AI providers.

Now is the time to set higher standards for AI procurement. Use Writer’s certifications and transparency as a benchmark and build internal evaluation processes that demand more than surface-level assurances. The next wave of enterprise AI won’t just be about capability—it will move forward on trust that can be proven.
