+
+## Implementation Notes
+
+### Authentication
+```go
+client := NewFluidStackClient("your-api-key")
+```
+
+### Project Scoping
+All instance operations require a project context:
+```go
+// All API calls include X-PROJECT-ID header
+// Projects provide isolation boundary for resources
+```
+
+### Security Model
+- **Project-Level Isolation**: Resources are isolated at the project level
+- **Default Network Behavior**: Instances can egress to internet, communicate within project
+- **Encryption**: Automatic encryption at rest and in transit
+
+## API Capabilities
+
+FluidStack provides a comprehensive Infrastructure API with the following endpoint categories:
+
+- **Projects**: Full CRUD operations for project management
+- **Instances**: Complete instance lifecycle management
+- **Instance Types**: Hardware configuration discovery
+- **Filesystems**: Storage management operations
+- **Kubernetes**: Managed Kubernetes cluster operations
+- **Slurm**: Managed Slurm cluster operations
+- **Capacity**: Real-time capacity checking
+
+## Compliance & Security
+
+FluidStack meets enterprise security requirements with:
+- Hardware-level disk encryption using self-encrypting drives
+- SSL/TLS encryption for all network traffic
+- Tier-3 data centers with biometric access controls
+- Multiple compliance certifications (HIPAA, GDPR, ISO27001, SOC 2)
+- Project-level network isolation using VXLAN and eBPF

+# FluidStack Security Compliance
+
+This document outlines FluidStack's security capabilities and compliance with Brev's security requirements.
+
+## ✅ FULLY COMPLIANT
+
+### Disk Encryption
+- **Encryption at Rest**: Hardware-level self-encrypting drives (SEDs)
+- **Implementation**: Automatic encryption without performance overhead
+- **Coverage**: All data stored on FluidStack infrastructure
+- **Standard**: Industry-standard encryption algorithms
+
+### Transit Encryption
+- **Protocol**: SSL/TLS encryption for all network traffic
+- **Coverage**: All API communications and data transfer
+- **Implementation**: Automatic encryption for all connections
+
+### Network Isolation
+- **Project-Level Isolation**: Dedicated L3 networks per project
+- **Technology**: VXLAN and eBPF for network segmentation
+- **Isolation Scope**: Hardware, network, and storage levels
+- **Multi-Tenancy**: Single-tenant by default, no shared clusters
+
+### Physical Security
+- **Data Centers**: Tier-3 facilities with 24/7 surveillance
+- **Access Controls**: Biometric access controls and mantrap entry systems
+- **Monitoring**: Continuous monitoring with CCTV coverage
+- **Personnel**: Restricted access to authorized personnel only
+
+### Compliance Certifications
+- **HIPAA**: Health Insurance Portability and Accountability Act
+- **GDPR**: General Data Protection Regulation
+- **ISO27001**: Information Security Management System
+- **SOC 2 TYPE I**: Service Organization Control 2
+
+## ⚠️ PARTIAL COMPLIANCE
+
+### Network Security Model
+- **✅ Outbound Traffic**: Instances can egress to public internet (compliant)
+- **✅ Project Isolation**: Strong isolation between projects (compliant)
+- **❓ Inbound Traffic**: "Deny all inbound by default" behavior not explicitly documented
+- **❓ Instance-Level Firewalls**: No API endpoints for individual instance firewall rules
+
+### Firewall Management
+- **Limitation**: Security managed at project/cluster level, not per-instance
+- **API Gap**: No dedicated firewall rule management endpoints in Infrastructure API
+- **Workaround**: Project-level isolation provides security boundary
+- **Impact**: May not provide granular instance-level firewall control
+
+## ❌ LIMITATIONS
+
+### Granular Network Control
+- **Missing Feature**: Individual instance firewall rule management
+- **Alternative**: Project-level network isolation
+- **API Support**: No explicit firewall rule endpoints found
+- **Security Model**: Relies on project boundaries for isolation
+
+### Network Security APIs
+- **Firewall Rules**: No API endpoints for creating/managing firewall rules
+- **Security Groups**: No security group concept or API
+- **Network ACLs**: No network access control list management
+
+## Security Implementation Notes
+
+### Default Security Posture
+```
+✅ Data encrypted at rest (hardware-level SEDs)
+✅ Data encrypted in transit (SSL/TLS)
+✅ Project-level network isolation (VXLAN/eBPF)
+✅ Physical security (Tier-3 data centers)
+❓ Instance-level firewall rules (not documented)
+❓ "Deny all inbound" default behavior (needs verification)
+```
+
+### Recommended Security Practices
+
+1. **Project Organization**: Use separate projects for different security zones
+2. **Network Design**: Leverage project-level isolation for security boundaries
+3. **Access Control**: Implement application-level security controls
+4. **Monitoring**: Use FluidStack's audit logging and monitoring features
+
+### Security Verification Required
+
+Before production deployment, verify:
+
+1. **Default Inbound Policy**: Confirm if inbound traffic is denied by default
+2. **Firewall APIs**: Check for any undocumented firewall management endpoints
+3. **Network Behavior**: Test actual network isolation and traffic patterns
+4. **Security Controls**: Validate project-level isolation effectiveness
+
+## Risk Assessment
+
+### Low Risk
+- **Data Encryption**: Excellent hardware-level encryption
+- **Physical Security**: Strong data center security controls
+- **Compliance**: Multiple enterprise certifications
+- **Network Isolation**: Strong project-level isolation
+
+### Medium Risk
+- **Firewall Management**: Limited granular network control
+- **API Limitations**: No explicit firewall rule management
+- **Documentation Gaps**: Some security behaviors not explicitly documented
+
+### Mitigation Strategies
+
+1. **Application Security**: Implement security controls at the application layer
+2. **Project Design**: Use project boundaries as security zones
+3. **Network Architecture**: Design applications to work within project isolation model
+4. **Monitoring**: Implement comprehensive logging and monitoring
+
+## Conclusion
+
+FluidStack provides **excellent foundational security** with hardware-level encryption, strong network isolation, and comprehensive compliance certifications. However, it may not provide the granular instance-level firewall management that some security models require.
+
+**Recommendation**: FluidStack is suitable for workloads that can leverage project-level security isolation. For applications requiring fine-grained instance-level firewall controls, additional verification and testing is recommended.
