Security & Reliability
Security is part of the architecture, not a final checklist.
Reliable systems require controlled access, sensible network boundaries, secure configuration, recovery procedures and operational visibility from the beginning.
Where security lives
Security areas we engineer
System hardening
- Linux and service configuration baselines
- Permissions and file ownership discipline
- Patching and update rhythm
Network architecture
- Segmentation and clear boundaries
- Reverse proxies, firewalls and VPN
- Controlled exposure of internal services
Identity & access
- MFA and single sign-on
- Role boundaries and least privilege
- Joiner-mover-leaver account processes
Application edge
- HTTPS and TLS configuration
- Reverse proxy policy and headers
- Access controls at the perimeter
Business email
- Postfix, Dovecot and Rspamd where self-hosted
- Spam filtering and mail routing
- Deliverability architecture
Backup & recovery
- Backup strategy with retention design
- Restoration tested on a schedule
- Snapshots and recovery procedures
Application security
Reviewing what the business depends on
Web applications and internal tools carry real risk when they hold business data. We review configurations, analyse exposure and run web application security testing with security scanners where appropriate — and prioritise findings by actual impact.
A backup that has never been restored is only an assumption.
Reliability is a practice: rehearsed recovery, monitored services, known failure modes and documentation that matches reality.
Monitoring
Alerts on symptoms the business feels — not noise
Recovery
Restore procedures rehearsed before they are needed
Updates
Planned lifecycle instead of emergency patching
Visibility
Logs and metrics retained, searchable, actionable
Proportionate protection
Security sized to the business
Enterprise engineering principles without enterprise overhead. Every control we add has a reason, an owner and a maintenance cost — and the architecture is documented so the next engineer understands why it is there.
- Risk-based decisions instead of checklist theatre
- Controls the team can actually operate
- Security documentation kept alongside the system
