## Technical Capabilities

### Security & Identity
- eBPF-based security event detection (process execution, privilege escalation, file modifications, lateral movement)
- Linux identity visibility: users, groups, sudo rules (including NOPASSWD, wildcards), SSH keys, PAM configurations, service accounts
- Privilege risk scoring: Detect toxic privilege combinations, forgotten NOPASSWD rules, escalation paths attackers exploit first
- Real-time drift detection: Configuration baseline monitoring with 60%+ MTTR reduction
- MITRE ATT&CK technique mapping: T1548 (Privilege Escalation), T1078 (Valid Accounts), T1098 (Account Manipulation)
- Behavioral anomaly detection: Unusual privilege usage, off-hours access, suspicious command patterns

### Compliance & Frameworks
- CIS Benchmarks: Automated assessment and remediation guidance for CIS Linux hardening controls
- NIST 800-53: Control mapping and evidence collection for federal/regulated industries
- NIS2 Directive: Identity governance gaps, incident detection/response, supply chain security
- DORA: ICT risk management, operational resilience, incident reporting for financial sector
- SOC 2 Type II: Access control evidence, audit trail integrity, change management compliance
- PCI DSS 4.0: Privileged account monitoring, access logging, authentication requirements
- HIPAA: Access control safeguards, audit trail requirements, administrative controls
- ISO 27001: Information security controls, access management, continuous monitoring

### Infrastructure Efficiency (FinOps)
- PSI (Pressure Stall Information) monitoring: Linux kernel metric (introduced 4.20) measuring CPU/memory/IO resource contention
- Automated rightsizing: Calculate optimal instance sizes based on actual utilization patterns
- Idle resource detection: Identify underutilized or abandoned infrastructure
- Cost quantification: Per-server cost estimates with multi-cloud provider pricing integration
- Efficiency scoring: 0-100 scale based on utilization, waste, and optimization opportunities
- ROI tracking: Measure cost reduction from optimization recommendations
- Multi-cloud visibility: Works across AWS EC2, Azure VMs, GCP Compute Engine, on-premises data centers

### Data Collection
- Lightweight agent: <1% CPU overhead, minimal memory footprint, no performance degradation
- eBPF probes: Kernel-level visibility without module loading, CO-RE (Compile Once, Run Everywhere) for kernel compatibility
- Read-only data collection: Non-invasive, no system modification during collection
- Encrypted transmission: TLS 1.3 for all data in transit, AES-256 at rest
- 30-second flush cycle: Near real-time signal ingestion for security events
- Configurable collection: Adjust frequency, scope, and retention policies per tenant

## Key Differentiators

- **Linux-native platform**: Purpose-built for Linux security and compliance, not retrofitted from Windows-first IAM
- **Three pillars converged**: Only platform combining Zero Trust identity, compliance automation, and infrastructure efficiency in single solution
- **eBPF security monitoring**: Kernel-level visibility without performance impact or module loading
- **NIS2-ready evidence**: Automated compliance reporting designed for European NIS2 Directive requirements
- **UK-based SaaS**: Data residency options for UK/EU regulated industries, GDPR-first architecture
