When evaluating virtual data room (VDR) providers, security is paramount. Organizations handling sensitive information—whether for M&A transactions, regulatory compliance, or strategic initiatives—need assurance that their VDR provider has robust security controls and has undergone rigorous security audits.
However, evaluating VDR security can be challenging. Security claims are often vague, and organizations may not know what to look for when assessing a VDR provider’s security posture. This guide explains what buyers should evaluate when conducting security audits of VDR providers, what certifications matter, and how to ensure your VDR provider meets your organization’s security requirements.
VDR providers should hold recognized security certifications that demonstrate their security posture has been independently verified. The most important certifications to look for are:
SOC 2 Type II Certification: SOC 2 Type II is the gold standard for SaaS security. This certification means an independent auditor has verified that the VDR provider has implemented appropriate security controls and has maintained those controls over an extended period (typically 6-12 months). SOC 2 Type II covers security, availability, processing integrity, confidentiality, and privacy.
When evaluating SOC 2 Type II reports, look for:
- Coverage of all relevant trust service criteria (security controls, encryption, access controls, audit logging)
- Extended audit period (6-12 months minimum)
- Any exceptions or management letters noting control deficiencies
- Clear documentation of the scope of the audit
ISO 27001 Certification: ISO 27001 is an international standard for information security management. This certification demonstrates that the VDR provider has implemented a comprehensive information security management system (ISMS).
When evaluating ISO 27001 certification, look for:
- Current certification (not expired) or compliance
- Coverage of the VDR service (not just the company generally)
- Regular surveillance audits (typically annually)
- Clear scope statement defining what’s covered
FedRAMP Authorization: For organizations deploying VDRs on AWS GovCloud or other government cloud platforms, FedRAMP authorization is important. FedRAMP authorization means the VDR provider has undergone rigorous security assessment and is authorized to serve U.S. government agencies.
Industry-Specific Certifications: Depending on your industry, additional certifications may be relevant:
- HIPAA Compliance: For healthcare organizations
- PCI DSS: For organizations handling payment card data
- SOX Compliance: For publicly traded companies
GDPR Compliance: For organizations handling EU resident data
Evaluating Specific Security Controls
Beyond certifications, organizations should evaluate specific security controls that are critical for VDR security:
Encryption: Evaluate how the VDR provider implements encryption:
- Is data encrypted in transit (using TLS/SSL)?
- Is data encrypted at rest (using AES-256 or equivalent)?
- Are encryption keys properly managed and protected?
- Does the provider support customer-managed encryption keys?
Access Controls: Evaluate the VDR provider’s access control implementation:
- Does the provider support role-based access controls (RBAC)?
- Can administrators define granular permissions at the document or folder level?
- Does the provider support multi-factor authentication (MFA)?
- Can administrators enforce MFA for all users?
- Does the provider support single sign-on (SSO) integration?
Audit Logging: Evaluate audit logging capabilities:
- Does the provider maintain comprehensive audit logs of all user actions?
- Are audit logs immutable and tamper-proof?
- Can administrators export audit logs for compliance reporting?
- Are audit logs retained for an appropriate period (typically 7 years for compliance purposes)?
Data Residency: For organizations with data residency requirements:
- Where is data stored geographically?
- Can customers choose data residency location?
- Does the provider support GovCloud or other specialized cloud regions?
- Are backups stored in the same region as primary data?
Disaster Recovery and Business Continuity: Evaluate the provider’s disaster recovery capabilities:
- Does the provider maintain geographically distributed backups?
- What is the recovery time objective (RTO)?
- What is the recovery point objective (RPO)?
- Has the provider tested disaster recovery procedures?
Conducting Your Own Security Assessment
Beyond reviewing certifications, organizations should conduct their own security assessments:
Request Security Documentation: Ask the VDR provider for:
- Current SOC 2 Type II report
- ISO 27001 compliance
- Security architecture documentation
- Incident response procedures
- Data retention and destruction policies
- Penetration testing results
Conduct Penetration Testing: Consider hiring a third-party security firm to conduct penetration testing of the VDR provider’s infrastructure. This independent assessment can identify vulnerabilities that formal audits might miss.
Review Incident History: Ask the VDR provider about past security incidents:
- Have there been any data breaches?
- How were incidents handled?
- What remediation steps were taken?
- What controls were implemented to prevent recurrence?
Evaluate Vendor Security Practices: Beyond the VDR platform itself, evaluate the provider’s security practices:
- Does the provider conduct regular security training for employees?
- Are employees required to undergo background checks?
- Does the provider have a responsible disclosure program for security researchers?
- Does the provider maintain a security roadmap addressing emerging threats?
VDR Security for GovCloud and Regulated Environments
For organizations deploying VDRs on GovCloud or in other regulated environments, additional security considerations apply:
GovCloud-Specific Security: If deploying on GovCloud, ensure the VDR provider:
- Understands GovCloud security requirements
- Can properly configure VDR security controls in the GovCloud environment
- Maintains appropriate audit logging for GovCloud compliance
- Supports data residency requirements for GovCloud
Compliance Reporting: Ensure the VDR provider can generate compliance reports demonstrating:
- Implementation of required security controls
- Audit logs demonstrating proper access controls
- Encryption implementation details
- Data retention and destruction procedures
Third-Party Risk Management: Evaluate the VDR provider’s third-party risk management:
- Does the provider conduct security assessments of its own vendors and subcontractors?
- Are subcontractors required to maintain equivalent security standards?
- Does the provider maintain a vendor risk register?
Red Flags to Watch For
When evaluating VDR providers, watch for these red flags:
- Lack of Current Certifications: If a VDR provider cannot provide current SOC 2 Type II or ISO 27001 certifications, this is a significant red flag.
- Vague Security Claims: Be skeptical of vague claims like “enterprise-grade security” without specific details or certifications.
- Unwillingness to Share Security Information: If a provider refuses to share security documentation or certifications, this suggests they may not have robust security controls.
- No Audit Logging: If a VDR provider cannot provide comprehensive audit logging, this is a critical deficiency.
- Unclear Data Residency: If a provider cannot clearly explain where data is stored and cannot guarantee data residency, this is problematic.
- No Disaster Recovery Plan: If a provider cannot articulate a clear disaster recovery and business continuity plan, this is a significant risk.
Making Your Decision
When evaluating VDR providers, security should be a primary consideration. Look for providers with current SOC 2 Type II and ISO 27001 certifications, robust security controls, and transparent security practices. Conduct your own security assessments and don’t hesitate to ask detailed questions about security implementation.
For organizations deploying VDRs on GovCloud or in other regulated environments, ensure the provider understands your specific compliance requirements and can demonstrate how their security controls support your compliance objectives.
By conducting thorough security audits and evaluating VDR providers carefully, you can select a provider that meets your organization’s security and compliance requirements and protects your sensitive information.
