Overview
At CloudNexus, data protection is engineered into every layer of our infrastructure. We follow a defense-in-depth strategy combined with a zero-trust architecture to ensure confidentiality, integrity, and availability of customer data. Our measures align with industry best practices and are continuously audited by independent third parties.
This document outlines the technical controls, organizational policies, and physical security measures that safeguard your workloads from provisioning to deletion.
Encryption Standards
All data managed by CloudNexus is encrypted both in transit and at rest. We support customer-managed keys (CMK) and bring-your-own-key (BYOK) workflows via AWS KMS, HashiCorp Vault, or our native key management service.
Encryption at Rest
AES-256-GCM encryption for block storage, object storage, and database volumes. Keys are rotated automatically every 90 days and stored in HSM-backed vaults.
Encryption in Transit
TLS 1.3 enforced across all public endpoints, internal service meshes, and inter-datacenter replication links. Certificate transparency and OCSP stapling enabled by default.
Key Management
FIPS 140-2 Level 3 validated hardware security modules (HSMs). Automated key rotation, granular access policies, and full audit trails for all cryptographic operations.
End-to-End Encryption
Optional client-side encryption for object storage and message queues. Metadata and filenames can be encrypted separately for maximum privacy.
Access Control & Identity Management
CloudNexus implements strict identity governance following the principle of least privilege. All administrative and customer access is continuously monitored and validated.
- Role-Based Access Control (RBAC): Granular permissions mapped to AWS IAM-like policies, supporting fine-grained resource-level authorization.
- Multi-Factor Authentication (MFA): TOTP, FIDO2/WebAuthn, and hardware security keys enforced for all console and API access. SSO via SAML 2.0 and OIDC.
- Session Management: Time-bound tokens, concurrent session limits, and automatic idle timeout. API keys support IP whitelisting and scoped permissions.
- Privileged Access Management (PAM): Just-in-time elevation, session recording, and break-glass procedures for emergency administrative access.
Network & Infrastructure Security
Our global infrastructure is segmented, isolated, and continuously protected against external and internal threats.
- VPC & Network Isolation: Fully isolated virtual networks per tenant. Subnet segmentation, route tables, and network ACLs configurable per environment.
- Web Application Firewall (WAF): OWASP Top 10 mitigation, rate limiting, bot management, and custom rule sets. Integrated with managed CDN.
- DDoS Mitigation: Multi-layered protection spanning L3, L4, and L7. AnyCast scrubbing centers with >2 Tbps capacity. Zero-cost mitigation included.
- Continuous Monitoring: 24/7 SIEM aggregation, automated anomaly detection, and behavioral analytics. Integration with PagerDuty, Slack, and custom webhooks.
Backup, Recovery & Data Lifecycle
Data resilience is guaranteed through automated, immutable backups and geographically redundant storage strategies.
- Automated Snapshots: Hourly incremental backups with configurable retention policies (7–365 days). Point-in-time recovery for managed databases.
- Immutable Storage: Write-once-read-many (WORM) compliance for regulatory requirements. Protection against ransomware and accidental deletion.
- Disaster Recovery: Active-active replication across regions. RPO < 1 minute, RTO < 5 minutes for enterprise tiers. Regular failover drills conducted quarterly.
- Data Sanitization: Cryptographic erasure upon volume deletion. Physical media destruction via NAID AAA certified vendors. Certificate of destruction provided.
Compliance & Certifications
CloudNexus maintains a rigorous compliance program validated by independent auditors. We publish an annual transparency report and maintain public compliance attestations.

Data Residency & Sovereignty
CloudNexus allows customers to pin data and compute to specific geographic boundaries. Cross-border data transfer is strictly controlled and requires explicit consent.
- Region Locking: Enforce data residency at the account level. Compute, storage, and metadata never leave selected zones.
- Subprocessing Control: Full visibility into downstream processors. Subprocessor change notifications 30 days in advance.
- Sovereign Cloud Options: Isolated tenancy with local admin teams, national compliance alignment, and air-gapped deployment capabilities for regulated sectors.
Incident Response & Transparency
Our Computer Security Incident Response Team (CSIRT) operates 24/7/365. We follow NIST SP 800-61 and ISO/IEC 27035 for incident management.
- Detection: Automated threat hunting, EDR/XDR integration, and behavioral analytics across all control planes.
- Containment & Eradication: Micro-segmentation, automated traffic shifting, and isolated quarantine environments.
- Notification: Customer notification within 1 hour of confirmed impact. Regulatory reporting within 72 hours per GDPR. Post-incident reports provided within 10 business days.
- Bug Bounty: Active program on HackerOne. Scope includes core infrastructure, console APIs, and managed services. Rewards up to $50,000.
