Vulnerability management type
Supplier-defined controls
Vulnerability management approach
Internal tools scan open ports on all our public IP addresses against a known configuration every 5 mins, we aim to remediate any misconfiguration within 1 hour. Qualys SSL tests are run every month and we aim for and 'A' rating on our public HTTPS endpoints, we aim to remediate any critical issues within 2 hours. Nessus Scan is run on all servers once a month, we aim to remediate 'critical' risks within 2 hours and 'high' risks within 1 day.
Protective monitoring type
Supplier-defined controls
Protective monitoring approach
We run behavioural activity monitoring software on our infrastructure to detect any anomalous activity on our servers. We immediately isolate the affected component from the network while we evaluate the impact. The server is cleaned and reprovisioned once investigations are complete. If deemed to be severe, we cycle all software secrets and keys to limit the impact of any potential data breach. We also run an open bug bounty program that encourages and compensates responsible disclosure of security issues with our system. We aim to remediate any design issues related to security with our software within 5 days.
Incident management type
Supplier-defined controls
Incident management approach
User incidents are reported via email to Our support evaluates the report and escalates to the appropriate team if necessary. We have a responsible disclosure policy to allow users to report vulnerabilities to the system. Hardware faults with our infrastructure are communicated by our supplier via email and as a ticket. Incidents are communicated to our users directly into the application as well as via a service availability webpage.
