  • Easy to understand reports for compliance and delivery rates.
  • Understand where threats originate with a world map visualisation.
  • Supports multiple domains and multiple users.
  • Average implementation time of 6 weeks for DMARC, SPF, DKIM.
  • Dynamic SPF to implement as many email services as needed.
  • Data history and activity log for up to 12 months.
  • API available to integrate results in your security dashboard.
  • UK Based provider. Data centres in London managed by IBM.
  • Investigate feature - in depth analysis of a particular email


  • Designed for self-service, OnDMARC speeds up and simplifies implementation.
  • Block phishing attacks that use your domain.
  • Stop email impersonation targeted at your staff and the public.
  • Maximise deliverability of your valid email communications.
  • Ensure proper configuration of your email security protocols SPF, DKIM.

Operational security

Operational security
Configuration and change management standard Supplier-defined controls
Configuration and change management approach We perform external port scanning, availability check systems and push based component metrics and alerting. Our API access uses an authentication approach based on JOSE and strong keys. We have a documented key cycling process to eliminate compromised or suspect keys.
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.
