Scaling

Independence of resources
User demand is controlled through logical separation, capacity planning, and active service management.

Each customer’s 3CX service is deployed with defined resource allocations and configuration boundaries appropriate to the agreed architecture.

Where shared infrastructure is used, resources are segmented and governed to prevent cross-customer contention, with continuous monitoring of performance and utilisation.

Renaissance proactively manages capacity, applies performance thresholds, and scales resources or adjusts configurations as required to maintain service quality.

Service levels are monitored to ensure one customer’s usage does not adversely impact another, and any required changes are managed through controlled operational processes.

Security governance

Named board-level person responsible for service security
Yes
Security governance certified
No
Security governance approach
Security governance is embedded within our organisational policies, operational processes, and management oversight. We align with the principles of the Software Security Code of Practice, ensuring security is considered throughout service design, delivery, and operation. Governance is maintained through documented security policies, defined roles and responsibilities, and management accountability. Security risks are identified and assessed, with proportionate technical and organisational controls implemented and reviewed regularly. Staff receive ongoing security awareness training, and access to systems is controlled using role-based access and least-privilege principles. Security incidents are managed through defined processes, with continuous improvement applied.
Information security policies and processes
Our organisation operates an information security management approach aligned to recognised best-practice standards such as ISO/IEC 27001, proportionate to the size, nature, and risk profile of the services delivered. Documented policies and procedures are in place covering access control, data protection, asset management, incident management, change management, supplier management, and business continuity. Overall accountability for information security sits at senior management level, with operational responsibility delegated to designated technical and service delivery leads. Security responsibilities are defined through role descriptions and supported by role-based access controls, least-privilege principles, and segregation of duties. Policies are embedded into service delivery processes and enforced through technical controls, standard operating procedures, and change control. Compliance is supported through staff induction, ongoing security awareness training, and clear reporting routes for suspected or actual security incidents. Security incidents are logged, investigated, and remediated in line with documented incident management procedures, with escalation to management where required. Policies and controls are reviewed periodically as part of service governance, risk assessment, and continuous improvement activities to ensure they remain effective and appropriate.
Software Security Code of Practice
Yes

Operational security

Configuration and change management standard
Supplier-defined controls
Configuration and change management approach
Our organisation operates supplier-defined configuration and change management controls aligned to recognised best-practice frameworks, proportionate to the services delivered. Changes are managed through a documented change process covering request submission, impact assessment, approval, implementation, and post-change review. Configuration baselines are maintained for infrastructure and services, with changes logged and traceable. Risk and service impact are assessed prior to implementation, and changes affecting availability or security are subject to formal approval. Where appropriate, changes are scheduled to minimise operational impact and include rollback procedures. All changes are recorded within service management tooling, providing auditability and supporting incident investigation and continuous improvement.
Vulnerability management type
Supplier-defined controls
Vulnerability management approach
We operate a supplier-defined vulnerability management process aligned to industry best practice. Potential threats are assessed through regular vulnerability scanning, vendor security advisories, and threat intelligence feeds from trusted sources such as software vendors, security bulletins, and NCSC guidance. Identified vulnerabilities are risk-assessed based on severity, exposure, and service impact. Patching and remediation are prioritised accordingly, with critical security updates deployed as soon as practicable and in line with change management controls. Vulnerability findings are tracked through to resolution, and remediation activity is reviewed to support continual improvement and reduce future risk.
Protective monitoring type
Supplier-defined controls
Protective monitoring approach
Protective monitoring is delivered using a combination of platform logging, security alerts, and operational monitoring tools. Potential compromises are identified through review of system logs, security events, performance anomalies, and alerts generated by infrastructure and application platforms. When a potential compromise is detected, incidents are triaged to assess severity, scope, and impact. Confirmed security incidents are escalated in line with incident management procedures and containment actions are taken where required. Response times are aligned to incident priority, with critical security incidents responded to immediately during service hours and escalated out of hours where necessary.
Incident management type
Supplier-defined controls
Incident management approach
We operate a supplier-defined incident management process with pre-defined procedures for common events such as service outages, security incidents, and performance degradation. Users report incidents via email or an online ticketing system, with incidents categorised and prioritised based on impact and urgency. Response and resolution targets align to agreed service levels. Customers are kept informed through regular updates during an incident. Following resolution, incident reports can be provided on request, including a summary of cause, actions taken, and any recommended preventative measures.
