Clear answers before you start.

No. The audit evaluates only publicly accessible DNS resource records and standard mail protocol configurations (like SPF, DKIM, DMARC, MTA-STS, DNSSEC, and MX) that any mail server on the internet already inspects when delivering an email to your organization.

We never access your mailboxes, credentials, or private message content, and no software or agents are installed. While DNS and mail protocol records are inherently public by design, we do not index domain results in a public directory or broadcast who ran an audit, and any personal details you submit are protected under EU GDPR.

Standard cloud suites provide baseline spam filters and mailbox storage, but their filtering can operate as an opaque black box. Because large vendors rely on broad, one-size-fits-all rules across millions of generic accounts, administrators often have little visibility into why a decision was made either way when an email is delivered, quarantined, or filtered.

Cirrus Invicta is designed to adapt to the unique workflows, trusted contacts, and communication patterns of your specific business. We pair transparent inbound threat protection, giving your team clear insight into filtering decisions, with active outbound governance so your domain cannot be spoofed by attackers.

Zero disruption. You do not need to overhaul your email infrastructure or rip and replace existing setups on day one.

We begin with non-intrusive discovery—auditing your domain and mapping your authentic sending services in the background. You gain complete visibility into your security posture and legitimate sender streams before enforcing any strict policies, ensuring 100% of authentic business emails continue delivering uninterrupted.
