Security Architecture
Our infrastructure employs multiple layers of security controls across physical, network, compute, and identity boundaries.
Physical Security
24/7 biometric access, mantraps, CCTV surveillance, and tamper-evident server racks across all Tier IV data centers.
Network Security
Anycast DDoS mitigation, VPC isolation, software-defined networking, and strict ingress/egress filtering with IPS.
Identity & Access
Multi-factor authentication, role-based access control (RBAC), SSO integration, and principle of least privilege enforcement.
Compute Isolation
Hypervisor-level isolation, hardware virtualization (Intel VT-x/AMD-V), and guest OS hardening with SELinux/AppArmor.
Data Protection & Encryption
All customer data is encrypted in transit and at rest using industry-standard cryptographic protocols. Key management is isolated and auditable.
Encryption in Transit
TLS 1.3 enforced globally. Forward secrecy via ECDHE. Mutual TLS for internal service mesh communication.
Encryption at Rest
AES-256-GCM for block storage and object storage. LUKS2 for ephemeral disks. FIPS 140-2 validated modules.
Key Management
Hardware Security Modules (HSMs) for key generation, rotation, and destruction. Customer-managed keys (CMK) available.
Backup & Recovery
Immutable snapshots, cross-region replication, and 3-2-1 backup strategy. RPO ≤ 15min, RTO ≤ 2h for critical workloads.
Compliance & Certifications
CloudNexus undergoes regular third-party audits and maintains compliance with major regulatory frameworks to support global enterprise requirements.
SOC 2 Type II
Annual independent audit of security, availability, and confidentiality controls. Latest report available under NDA.
ISO 27001:2022
Internationally recognized ISMS certification covering risk management, incident response, and continuous improvement.
GDPR & Data Residency
Full compliance with EU data protection regulations. Regional data residency guarantees and DPA templates available.
HIPAA Eligible
Infrastructure and controls meet HIPAA security rule requirements. BAA available for covered entity customers.
Shared Responsibility Model
Cloud security is a partnership. Understanding the division of responsibilities ensures optimal protection for your workloads.
CloudNexus Responsibilities
- Physical security of data centers and hardware
- Hypervisor, networking, and infrastructure firmware updates
- Platform availability, redundancy, and disaster recovery
- Encryption implementation and key management infrastructure
- Internal security monitoring, logging, and incident response
- Compliance auditing and certification maintenance
Customer Responsibilities
- Guest OS patching, hardening, and firewall configuration
- Application-level security, WAF rules, and dependency scanning
- Identity management, IAM policies, and credential rotation
- Data classification, access controls, and backup verification
- Network segmentation, security groups, and route tables
- Compliance validation for data processed and stored
Vulnerability Management & Bug Bounty
We maintain a continuous security testing program and reward ethical researchers who help us identify vulnerabilities.
Patching SLAs
Critical infrastructure vulnerabilities are patched within 24-48 hours. Guest OS images receive automated security updates daily. Zero-downtime patching available for managed services.
Penetration Testing
Quarterly third-party penetration tests across all public-facing APIs, admin consoles, and network boundaries. Customers may conduct authorized pen tests on their workloads with prior notification.
Responsible Disclosure
We operate a coordinated vulnerability disclosure program. Researchers are acknowledged in our security advisories. Bounties range from $500 to $25,000 based on severity and impact.
Report a Security Concern
If you believe you've found a vulnerability in CloudNexus infrastructure or services, please report it immediately. We respond to all reports within 24 hours.
