ISMAP Readiness Assessment & ISMAP Audits

End-to-end support for SaaS, PaaS and IaaS providers supplying Japanese government agencies — from first gap analysis through formal audit and re-assessment.

What is ISMAP?

The procurement gate for Japan’s public-sector cloud market

ISMAP (Information System Management and Assessment Program) is the Japanese government security assessment framework for cloud services. Any provider selling SaaS, PaaS or IaaS to central or local government agencies must clear an ISMAP assessment. Spider X helps you understand the baseline, close gaps and produce the evidence an assessor expects.

FAQ

Common ISMAP readiness and audit questions

What is ISMAP?

ISMAP (Information System Management and Assessment Program) is the Japanese government framework used to assess the security of cloud services procured by public-sector agencies. Compliance is typically a prerequisite for supplying SaaS, PaaS or IaaS to Japanese government bodies.

What is the difference between an ISMAP readiness assessment and an ISMAP audit?

A readiness assessment is a pre-assessment engagement that identifies gaps, builds your evidence pack and prepares you for a formal assessor. An ISMAP audit is an independent assurance review that tests controls and produces the formal report required for procurement gates.

How long does an ISMAP readiness assessment take?

Most readiness assessments run for 8–16 weeks, depending on the size of the service, the maturity of existing controls and how quickly evidence can be supplied.

How long does a formal ISMAP audit take?

A formal ISMAP audit typically takes 8–14 weeks from kick-off to final report, including evidence evaluation, control testing, assessor review and remediation validation.

When should we start the process?

Ideally 3–6 months before an RFP submission, contract renewal or planned go-live with a Japanese government agency. Starting early gives time to remediate gaps without delaying the deal.

Do we need a Japanese legal entity or local assessor?

You do not need a Japanese entity to engage us. Formal ISMAP audits must be conducted by accredited assessors; we prepare you for that review and can coordinate with local assessors on your behalf.

What evidence will we need to provide?

Common evidence includes security policies, access management records, change control logs, incident reports, network and architecture diagrams, cloud shared-responsibility models, subcontractor agreements and penetration-test results.

What happens after the audit is complete?

You receive a management report with findings, severity ratings and a remediation plan. We then support finding closure, re-assessment and continuous compliance monitoring so you remain audit-ready.

Can you help with re-assessment?

Yes. ISMAP requires periodic re-assessment and continuous monitoring. We run retained readiness programs that track changes, test controls quarterly and prepare you for each re-assessment cycle.
