Security
Security is the foundation, not a feature
Nexus Kilima is engineered to meet the trust and control expectations of regulated financial institutions — with defence in depth across ten core areas.
Security architecture
Ten layers of defence in depth
Encryption
Data is encrypted in transit using TLS and at rest using strong, industry-standard algorithms, protecting sensitive financial information end to end.
Authentication
Multi-factor authentication for staff and customers, with session management, device awareness and configurable password policies.
Authorization
Every request is authorised against fine-grained policies, so users can only perform the actions they are explicitly permitted to.
Role-Based Access Control
RBAC maps precisely to your organisational structure, enforcing least privilege and clear separation of duties across branches and teams.
Audit Logs
Immutable, exportable audit trails record every sensitive action, supporting accountability, investigation and regulatory review.
Data Protection
Privacy-by-design, data minimisation and configurable retention controls protect customer information throughout its lifecycle.
Backup Strategy
Automated, encrypted backups run on a regular schedule, with integrity checks to ensure data can be reliably restored.
Disaster Recovery
Documented recovery procedures and tested restoration processes are designed to minimise downtime and data loss in adverse events.
High Availability
Resilient, redundant architecture with continuous monitoring is engineered to keep critical services available.
API Security
APIs are protected with authentication, authorisation, rate limiting and input validation to keep integrations secure.
Our commitment
A security posture your regulators and board can trust
From encryption and access control to auditability and resilience, every capability is built to withstand scrutiny. Masha Nexus treats the security of your institution and its customers as a first-order engineering priority — and we do not claim certifications we have not yet earned.
