A penetration test tells you where you are vulnerable. Systems security is what you do about it. We harden your infrastructure, configure access controls, set up monitoring and provide the ongoing managed security operations that keep your environment protected as threats evolve.
Infrastructure hardening
Every server, network device and application has a default configuration that prioritises ease of setup over security. Hardening is the systematic process of removing unnecessary services, closing unused ports, applying security patches and configuring systems according to established benchmarks like CIS (Centre for Internet Security) standards.
We harden across the full stack - operating systems, web servers, databases, container runtimes and cloud configurations. This includes SSH key management, firewall rule auditing, TLS configuration, file system permissions and service account isolation. The goal is to reduce your attack surface to the minimum required for your systems to function.
Access control and privilege management
Uncontrolled access is the root cause of most security incidents. We implement the principle of least privilege across your infrastructure - every user and service account gets only the permissions they need, nothing more.
This includes configuring role-based access control (RBAC), setting up multi-factor authentication for administrative access, implementing jump hosts for server management, and auditing existing permissions to remove accumulated access that is no longer needed. For organisations using Keycloak, we integrate identity management directly into your infrastructure access layer.
Encryption
We configure encryption at rest and in transit across your infrastructure. This includes TLS certificates for all public-facing services, disk encryption for data at rest, encrypted database connections and VPN tunnels for inter-site communication. We manage certificate lifecycles to prevent the expired certificate outages that catch many organisations off guard.
Continuous monitoring and alerting
Security without visibility is guesswork. We deploy monitoring across your infrastructure that tracks system resource usage, authentication events, configuration changes, network traffic patterns and known indicators of compromise. Alerts are configured to notify your team and ours when thresholds are breached or anomalous activity is detected.
Our monitoring integrates with the broader automation platform - Apache APISIX logs API access patterns, Kafka streams security events for real-time correlation, and Superset dashboards provide visual security posture reporting.
Managed security operations
Our managed security model means we do not hand you a report and walk away. We apply patches, rotate credentials, review logs, respond to alerts and continuously tune your security configuration as your infrastructure evolves and new threats emerge. Regular reporting ensures your leadership team has clear visibility of your security posture and compliance status.
We are ISO 27001 and Cyber Essentials certified.
