Onboarding and offboarding
- Getting started
- You will begin using the service with a kick-off meeting, organised by your named Customer Success Manager, during which your success plan, implementation project, and preparation phase will be defined. We provide a blueprint Gantt chart and RACI matrix, which can be tailored to suit your specific implementation requirements. You will be assigned a Customer Success Engineer (CSE) who will assess the scale of the implementation, contribute to detailed planning, and help define realistic timeframes. User documentation is available within the application, through our knowledge base, and via our online community, SiftSpace, allowing you to choose the format most convenient for you. You can choose between online or onsite training, scheduled at times that suit your organisation. Training can also be requested both before and after implementation, as required. During the implementation process, you will be given access to the application to begin the necessary configuration activities..

Availability and resilience
- Guaranteed availability
- Guaranteed availabilityRed Sift provides customers with access to the SaaS production application on a 24x7 basis, with a product-specific uptime target of 99.9%. The uptime obligation begins on the Go Live Date, defined as the point at which end-user testing has been completed, the production environment has been prepared, and the service has been made available to the customer. Uptime is measured monthly using the total measurable hours in the month, excluding any scheduled maintenance, as the denominator. The numerator is calculated by subtracting the total duration of any Severity 1 (S1) outages during the month from the measurable hours, resulting in the percentage of available uptime. An outage is defined as an S1 incident lasting at least five minutes, continuing until the issue is resolved, a workaround is provided, or the incident is downgraded to Severity 2 (S2). Where required as part of a contract, service crs may be agreed on a case-by-case basis.
- Approach to resilience
- We operate multiple availability zones within our primary data centre and use a geographically distributed cluster architecture with dual redundancy, including warm standby clusters, to maximise service availability. Full backup snapshots are taken every 45 minutes and stored on resilient, NFS-based object storage. The platform is built on a scalable microservices architecture with a persistent job queue, providing resilience and fault tolerance across most planned and unplanned outages.
- Outage reporting
- Outages are communicated to customers via email alerts, notices published in our customer community, and updates posted to our public status page to ensure timely and transparent communication during service incidents.

- Red Sift has adopted ISO 27001 as the foundation for its information security programme and Information Security Management System (ISMS). Other relevant standards, frameworks, and regulatory requirements are mapped to the ISMS to ensure alignment with industry best practices and support continual improvement. The ISMS is governed by defined objectives and supported by a comprehensive set of policies, including classification and handling, asset management and acceptable use, access control, third-party management, secure development, incident management, business continuity, competence and awareness, risk management, and compliance. The ISMS is actively operated and reviewed throughout the year, supported by regular Information Security Committee meetings, scheduled risk reviews, and an internal audit programme. Red Sift undergoes annual external assessments by independent professional bodies to verify continued alignment with ISO 27001, SOC 2, and other applicable standards mapped to the ISMS. Adherence to the ISMS is enforced through the Competence and Awareness policy, which defines information security requirements for new and existing employees. Overall responsibility for the ISMS rests with the Information Security Manager, currently the Chief Technology Officer, who is accountable for ensuring compliance with ISO 27001:2022 and other standards, and for reporting on the effectiveness of the ISMS to internal and external stakeholders.
Operational security
- Configuration and change management standard
- Complies with a recognised standard, for example CSA CCM v4.0 or SSAE-18 / ISAE 3402
- Configuration and change management approach
- Our Secure Development Policy and ISMS processes support a continuous delivery model with layers of change management and verification throughout the lifecycle. These processes ensure components are tracked end to end and the security impact of changes is assessed. Security is embedded at each stage of development, including requirements in the design phase, secure coding practices, story creation, sprint planning, assignment and design, security review, implementation documentation, peer review, dependency review, quality assurance, deployment to staging, deployment approval, deployment to production, and post-deployment monitoring. Security training and prioritisation of security and user-facing issues after deployment are integral to the process.
- Vulnerability management type
- Complies with a recognised standard, for example CSA CCM v4.0 or SSAE-18 / ISAE 3402
- Vulnerability management approach
- Vulnerability scans of our infrastructure are performed monthly. We operate a responsible disclosure process that rewards researchers for the reporting of vulnerabilities. Our infrastructure is based on a microservices architecture, with container images scanned for vulnerabilities during the build process. Source code is hosted on GitHub, with Dependabot enabled to identify outdated or vulnerable dependencies. We monitor vulnerability information from mailing lists and other sources. A third party conducts a penetration test. All vulnerabilities identified through these activities are managed through our vulnerability management process, categorised by severity, and remediated as quickly as possible, typically within one week or sooner.
- Protective monitoring type
- Complies with a recognised standard, for example CSA CCM v4.0 or SSAE-18 / ISAE 3402
- Protective monitoring approach
- We use pattern-based alerts in Datadog to detect anomalous activity. Alerts are delivered to our Slack channels, where they are assessed, analysed, and actioned by the team. Out-of-hours coverage is provided through a 24x7 on-call schedule, with critical alerts escalated via PagerDuty. All access to production systems is logged, with additional alerts configured to support forensic investigation.
- Incident management type
- Complies with a recognised standard, for example, CSA CCM v4.0 or ISO/IEC 27035:2011 or SSAE-18 / ISAE 3402
- Post-quantum cryptography secure
- Yes
- Incident management approach
- Our incident management process follows the SANS Institute PICERL model and includes predefined procedures for common incident types. Users are required to report any security-related incidents, events, or weaknesses immediately via internal messaging for management review. Incidents originating from third-party suppliers are reported through the same process. Anomaly detection alerts are also in place to identify unusual system activity. Lessons learned from incidents are documented as corrective actions within the same tracking system, with appropriate tagging based on the required follow-up. All incidents are formally documented, with incident reports created and logged separately.
