You have deployed your infrastructure, written your policies, trained your employees, and collected your evidence. Now comes the part that makes most vendors nervous: the actual audit. Understanding exactly what happens during a CCC assessment -- who conducts it, what they look for, how long it takes, and where vendors typically stumble -- eliminates surprises and dramatically increases your chances of passing on the first attempt. This guide walks you through the entire audit process from start to finish.
Who Conducts the Audit
CCC audits are conducted exclusively by authorized audit firms approved by Aramco's Cybersecurity Compliance Department. You cannot self-certify, and you cannot use a generic cybersecurity consultant. The audit firm must be on Aramco's approved list.
Key point: Choosing the right audit firm matters. Some firms are more experienced with specific vendor types (IT companies, construction firms, logistics providers). MassiveGRID maintains partnerships with authorized audit firms and can connect you with assessors who understand infrastructure-centric vendors.
The audit firm assigns one or more assessors who are trained on the SACS-002 standard. They evaluate your organization against the applicable TPC controls and produce a report that Aramco uses to issue (or deny) the certificate.
CCC vs CCC+ Assessment: What is Different
Aramco issues two types of certificates, and the assessment process differs significantly between them:
| Aspect | CCC (Standard) | CCC+ (Enhanced) |
|---|---|---|
| Vendor type | Vendors without remote/network access to Aramco systems | Vendors with remote or network access to Aramco systems |
| TPC controls assessed | Subset of TPC controls (governance, email, basic security) | Full set of TPC controls (all governance + technical controls) |
| Technical depth | Policy review + basic technical verification | Deep technical assessment including network scans, configuration review, penetration testing |
| Assessment duration | 1-3 days typically | 3-7 days depending on scope |
| On-site component | May be remote-only for smaller vendors | Typically includes on-site inspection of facilities and systems |
| Validity period | 2 years | 2 years |
Most vendors working with MassiveGRID's infrastructure package are pursuing the standard CCC certificate. If your contract with Aramco requires remote access to their systems, you will need CCC+ and should plan for a more extensive assessment. For a detailed comparison, see our CCC vs CCC+ guide.
The Audit Process: Step by Step
Phase 1: Engagement and Scoping
The process begins when you engage an authorized audit firm. During the scoping phase:
- The audit firm reviews your Aramco contract to determine which certificate type is required (CCC or CCC+)
- They identify the applicable TPC controls based on your vendor category and the services you provide to Aramco
- An assessment schedule is agreed upon, including dates, participants required, and any on-site visits
- The audit firm provides a document request list -- a checklist of policies, configurations, and evidence they need to review
This phase typically takes 1-2 weeks. Use this time to gather your evidence and conduct an internal pre-assessment.
Phase 2: Document Review
Before any technical testing, the assessor reviews your governance documentation. This is where the majority of first-time failures occur -- not in technical controls, but in missing or inadequate policies.
The assessor will request and review:
- Acceptable Use Policy (TPC-1): Document, employee acknowledgments, distribution records. See our AUP guide.
- Incident Response Plan (TPC-23): Document, contact roster, tabletop exercise records. See our IRP guide.
- Data Classification Policy: Document, classification mapping to Aramco levels, handling rules. See our Data Classification guide.
- Risk Assessment: Documented risk assessment showing identified threats, vulnerabilities, and mitigations
- Security Awareness Training records (TPC-7): Training completion records for all employees within the last 12 months
- Employee roster: Complete list of employees with access to Aramco data or systems, cross-referenced against policy acknowledgments and training records
- Off-boarding records (TPC-6): Evidence that departed employees had access revoked within 24 hours
The assessor will check for completeness (all sections present), currency (reviewed within 12 months), coverage (all employees included), and specificity (policies address SACS-002 requirements, not generic IT governance).
Phase 3: Technical Assessment
With governance documentation reviewed, the assessor moves to technical verification. This phase confirms that your documented policies are actually implemented:
Infrastructure Verification
- Email configuration (TPC-8/9/10): DNS records checked for SPF, DKIM, DMARC. Mail server configuration reviewed for SPF validation. Private domain verified.
- Encryption (TPC-52): TLS configuration verified on all services. Encryption-at-rest confirmed for file storage.
- Firewall rules (TPC-4/5): Firewall configuration reviewed, default-deny verified, unnecessary ports confirmed closed.
- VPN configuration (TPC-12): Remote access requires VPN, VPN encryption strength verified, split tunneling disabled.
- Password policies (TPC-2/3): Password complexity, history, rotation, and lockout settings verified in system configurations.
- MFA (TPC-3): Multi-factor authentication enabled on all cloud-accessible systems, MFA enrollment verified for all users.
- Patch management (TPC-11): Patching records reviewed, critical patches applied within required timeframes.
- Backup configuration: Backup schedules, retention periods, and restoration testing records reviewed.
- Monitoring and logging (TPC-16): Log collection, retention, and alerting verified.
Evidence Collection
For each technical control, the assessor collects evidence -- typically screenshots, configuration exports, or live demonstrations. This is where pre-prepared evidence packages save enormous time. If you need to log into 5 different systems and navigate to configuration pages during the assessment, you will burn hours of audit time.
Phase 4: Findings and Remediation
After the assessment, the audit firm produces a report categorizing each TPC control as:
- Compliant: Control is implemented and evidence is satisfactory
- Non-compliant: Control is missing, inadequate, or evidence is insufficient
- Partially compliant: Control is partially implemented but has gaps
- Not applicable: Control does not apply to your vendor category
If you have non-compliant findings, you will receive a remediation period (typically 30-90 days depending on the severity) to address the gaps. After remediation, the auditor re-assesses only the failed controls.
First-attempt pass rate: Vendors using a turnkey infrastructure package with pre-configured controls and ready-made policy templates have a significantly higher first-attempt pass rate than vendors who self-implement. The most common failures are governance gaps (missing policies, incomplete acknowledgments) rather than technical controls.
Phase 5: Certification
Once all controls are assessed as compliant, the audit firm submits its report to Aramco's Cybersecurity Compliance Department. Aramco reviews the report and, if satisfied, issues the CCC or CCC+ certificate. The certificate is valid for 2 years, after which you must undergo a renewal assessment.
Common Day-of Audit Mistakes
- Key personnel unavailable: The IT administrator who manages the firewall is on vacation. The assessor cannot verify firewall rules and must reschedule, adding weeks to the timeline.
- Evidence not pre-organized: The assessor asks for password policy configuration. The IT team spends 30 minutes searching for the right admin panel and cannot find the exact setting. Disorganized evidence wastes audit time and creates a poor impression.
- Stale contact information in IRP: The assessor asks to see the Incident Response Plan. The Aramco contact phone number listed is from 2 years ago. The assessor flags this as a TPC-23 gap -- the IRP has not been maintained.
- Employee training gaps: The assessor cross-references the employee roster with training records and finds 3 employees hired in the last 4 months who never completed security awareness training. Incomplete TPC-7 compliance.
- Test accounts still active: The assessor reviews the user accounts list and finds accounts belonging to former employees or test accounts with weak passwords. Access management failure.
- Mismatched policy dates: The AUP says "Last reviewed: January 2025" but the employee acknowledgments are from 2024. The assessor concludes the policy was updated but employees never re-acknowledged the new version.
Pre-Audit Checklist
Complete this checklist in the 2 weeks before your audit date:
| Category | Action Items |
|---|---|
| Governance | Verify all policies have current review dates, all employees have signed acknowledgments, training records are 100% complete |
| People | Ensure key personnel are available on audit day, brief employees on the assessment process, verify IRP contact information is current |
| Technical | Run internal checks on all TPC controls (DNS records, firewall rules, password policies, MFA enrollment, patch status, backup logs) |
| Access | Review user accounts list, disable/remove inactive accounts, verify no departed employees retain access, confirm MFA is enrolled for all users |
| Evidence | Pre-capture screenshots of all technical configurations, organize in a folder structure matching TPC controls, prepare a master evidence index |
| Logistics | Confirm audit dates with the audit firm, prepare meeting room or video conference, ensure admin access to all systems for live demonstrations |
After the Audit: Renewal and Ongoing Compliance
CCC certificates are valid for 2 years. Plan your renewal assessment at least 3 months before expiration to account for scheduling, assessment time, and any remediation needed. Between audits:
- Continue annual security awareness training for all employees
- Review and update policies annually (record the review even if no changes are made)
- Maintain patching and monitoring disciplines
- Conduct annual IRP tabletop exercises
- Process employee off-boarding within 24 hours (TPC-6)
- Keep evidence organized throughout the 2-year cycle -- do not scramble before renewal
For more details on the renewal process, see our CCC renewal guide.
How MassiveGRID Simplifies Your Audit
The biggest advantage of a turnkey CCC infrastructure package is that audit evidence is built into the platform. MassiveGRID's CCC-Compliant Infrastructure Package provides:
- Pre-configured technical controls: Every TPC control that has a technical component (email, firewall, VPN, encryption, MFA, patching, backups, monitoring) is configured correctly from day one. No manual setup, no configuration drift.
- Ready-made policy templates: Six governance templates (AUP, IRP, Data Classification, Risk Assessment, Off-boarding Checklist, Media Sanitization) written for CCC compliance and accepted by authorized audit firms.
- Evidence documentation: Configuration evidence is pre-captured and organized by TPC control. When the assessor asks for firewall rules, you open a folder -- not an admin console.
- Authorized audit firm partnerships: MassiveGRID connects you with authorized CCC audit firms who understand infrastructure-centric vendors and can schedule your assessment efficiently.
- Ongoing compliance support: The package includes annual policy reviews, training updates, and evidence refresh for the 2-year certification cycle.
The result: vendors using the full package typically complete their assessment in 1-2 days with minimal remediation findings, compared to 3-5 days with multiple remediation rounds for vendors who self-implement.
