Take control of
your email security.
Email is the #1 attack vector — yet most organisations can't say with confidence what controls they have, whether they're working, or who's responsible. From inbound threat protection to continuous email governance, Cirrus Invicta changes that.

The Email Security Problem
Why "set and forget" isn't security.
The #1 Attack Vector
Email is still the entry point for most breaches. Yet controls are deployed once and rarely reviewed.
No Visibility
If your email security controls fail silently, you may not know until something goes wrong.
No Accountability
When incidents happen, nobody knows who owns what, what changed, or when. The trail goes cold.
Accountability over "Trust Us"
From perimeter inbound threat protection to continuous policy validation — four ways we bring visibility and control to your email stack.
Continuous Validation
Automated checks for DMARC, SPF, DKIM enforcement. We don't just check configuration; we validate operational status.
Continuous Enforcement
Move beyond "it's configured" to "it's working". Know your controls are active, not just deployed.
Change Control & Approvals
Track who approved policy changes. Bind every configuration update to an owner and an approval date.
Drift Detection
Get alerted when configuration drifts from the approved baseline. Maintain a historical audit trail automatically.
