SOC 2 CC9 business continuity evidence for on-premises data centers

What CC9 auditors sample

CC9 covers how the entity identifies, develops, and implements controls to mitigate risks — including availability and continuity. Auditors expect a documented business continuity plan and disaster recovery plan, a business impact analysis defining RTOs and RPOs, and evidence that recovery procedures were tested during the observation window.

For Type 2 reports they sample specific dates: backup restoration logs, failover test output, change records, and incident tickets — not a single annual summary. Narrative-only deliverables that describe how recovery should work, without tying procedures to validated infrastructure state, are a common source of exceptions.

Where cloud compliance automation stops

SOC 2 automation platforms excel at policy templates, integration evidence, and continuous control tests for cloud-native SaaS. They are weaker when the scope includes bare-metal and virtualized data-center estates — NX-OS fabrics, vSphere clusters, ONTAP volumes, and the dependencies between them.

CC9 still applies to those systems. Auditors ask how recovery runbooks reflect current topology, whether backup coverage was validated end-to-end, and whether RTO/RPO targets in the BIA match what the technical environment can deliver.

MKDC deliverables mapped to CC9 evidence

MKDC packages discovery, recovery documentation, and compliance reporting in one fixed-fee engagement, fixed fee · 4–6 weeks. The witness bundle lets your auditor or a third party re-derive conclusions from source captures and validation logs — without re-engaging us for every follow-up question.

• Validated inventory and L2/L3 topology from read-only management API capture
• Cross-tier dependency map validated before publish
• RTO/RPO matrix and prioritized DR gap analysis
• Recovery runbooks ordered by the dependency map
• SOC 2 CC9 subset mapping with per-control gap analysis
• Reproducible witness bundle — any third party can re-derive every conclusion

CC9 evidence auditors request during Type 2 sampling

SOC 2 auditors sample specific dates. A runbook that was accurate in January but stale by September is a common exception when the observation window spans infrastructure projects, data center consolidations, or storage migrations.

• Business continuity plan and disaster recovery plan versions in effect during the observation period
• Business impact analysis with RTO and RPO per system or tier in scope
• Backup job success logs plus restoration or failover test output — not scheduler screenshots alone
• Change tickets for critical systems that moved, resized, or renumbered during the window
• Incident records where recovery procedures were invoked or should have been
• Evidence that recovery runbooks reflect infrastructure state on sampled dates

Mapping MKDC artifacts to CC9 control narratives

CC9 control narratives in your SOC 2 binder describe how the entity mitigates availability risk. MKDC supplies the technical evidence those narratives depend on: validated inventory and L2/L3 topology from read-only capture, a cross-tier dependency map checked before publish, recovery runbooks ordered by that map, and per-control gap analysis for the CC9 subset.

The witness bundle ties each gap status to source captures and validation logs. When your SOC 2 automation platform holds policy attestations and integration evidence, MKDC fills the gap for on-premises data center estates — the systems cloud GRC templates rarely capture in operational detail.

Preparing for your observation window

Sponsor the engagement early enough in the Type 2 period that capture reflects production state auditors will sample — typically four to six weeks before the heaviest infrastructure evidence requests, or immediately after a major migration when runbooks are known to be stale.

MKDC does not replace your auditor or automation platform. We deliver infrastructure evidence timed to CC9 sampling so your internal team can respond to follow-up questions with reproducible artifacts instead of reconciling conflicting spreadsheets under deadline pressure.

CC9 and availability risk narratives

Availability risk in SOC 2 is both program and technical. CC9 narratives describe how the entity responds to disruption; auditors still sample whether DR plans and runbooks match systems in scope. A polished availability narrative with stale runbooks produces the same exception as a missing BCP.

MKDC aligns technical artifacts to the observation window so your availability story and your infrastructure evidence describe the same estate on the same dates.

Hybrid estates: SaaS plus on-premises data centers

Many SOC 2 reports cover both cloud SaaS and on-premises infrastructure. Your automation platform holds integration and policy evidence for the SaaS portion; MKDC holds inventory, topology, runbooks, and CC9 gap analysis for the data center portion.

The cross-framework index in the witness bundle shows how infrastructure evidence supports CC9 without duplicating cloud control work. Auditors sampling on-premises systems receive traceable artifacts instead of cloud policy exports that do not describe VMware or switching state.

Complementing your existing SOC 2 program

MKDC does not replace your SOC 2 automation platform or internal GRC workflow. We deliver audit-grade infrastructure evidence timed to your observation window when the gap is documented recovery posture for on-premises systems — not when you only need another policy attestation in a SaaS dashboard.

We are a partial fit when you need a facilitated tabletop exercise or formal attestation signature today; we deliver the advisory documentation those reviews depend on. Advisory, not formal attestation.

When your SOC 2 scope includes both SaaS and on-premises systems, use MKDC for the data center estate and your existing automation platform for cloud controls — the witness bundle and cross-framework index show how infrastructure evidence supports CC9 narratives without duplicating policy work.
