Email security service by Navixia

Businesses today face growing risks from phishing, CEO fraud and domain spoofing, often through emails that appear to come from their own brand.

Email flows have become increasingly diverse across SaaS platforms, automated systems, marketing tools, partners and internal services, making them difficult to control. As a result, implementing security mechanisms such as SPF, DKIM and DMARC can be complex, time-consuming and sometimes uncertain.

Navixia provides an SPF/DKIM/DMARC service to address these challenges.

Navixia email security service

We help you secure your organisation’s email identity, understand who is sending email from your domains, and manage a gradual, controlled implementation of DMARC protection without negatively affecting deliverability.

Our engineers handle the design, compliance and optimisation of SPF and DKIM records, while our DMARC platform provides the visibility, analysis and ongoing monitoring needed to manage DMARC deployment and compliance effectively. This includes dashboards, alerts, aggregate report analysis and assistance with a phased rollout.

The objectives of the service are:

reduce the risk of spoofing, phishing and fraud carried out in the name of your domain
improve the deliverability of your legitimate emails
notify technical teams when new email-sending services are introduced or spoofing attempts are detected

Two pillars: human expertise + a specialised platform

A successful email authentication project does not rely on a tool alone. The quality of the configuration depends on a clear understanding of email flows, authorised third-party services and the customer’s technical constraints. Our service helps organisations secure their sending domains and regain control of their email identity. It is built around two pillars:

Our engineers, who specialise in configuring and optimising SPF and DKIM, handle the analysis of outbound email flows, SPF rationalisation, DKIM configuration and technical remediation.
The Red Sift OnDMARC platform monitors DMARC reports, identifies legitimate senders, detects anomalies and supports the gradual strengthening of protection measures.

This approach helps prevent common deployment issues, such as overly broad SPF records, exceeding the DNS lookup limit, misaligned DKIM signatures or enforcing a restrictive DMARC policy too quickly.

Best practice is to begin by monitoring emails sent on behalf of the domain, then gradually strengthen the security controls. Once legitimate sending sources have been clearly identified and brought under control, a policy can be defined for messages that do not come from authorised sources.

What the service provides

Assessment of the existing environment: domains, subdomains, outbound email flows, SaaS providers, routing and current email authentication levels.
Review and optimisation of SPF records to reduce unnecessary authorisations and avoid DNS configuration issues.
Implementation or remediation of DKIM, including alignment with sending domains and recommendations on key strength and rotation.
DMARC deployment and configuration, with monitoring through the platform, analysis of aggregate reports and prioritisation of remediation actions.
Regular review meetings to address remediation actions and correct non-aligned domains.
Guidance on the path to compliance: from none to quarantine, then reject, depending on the assessed level of maturity.
Reporting and review meetings to give the CISO, IT management and senior management a clear view of the environment.
Notifications setup once the DMARC policy has been moved to reject.
