KOVA OS · SHIELD

Make it harder for impersonators to send email using your business domain.

Check the public records behind your business email free. Shield reviews approved senders and prepares authentication changes for your written approval.

$750 one-time · 1 business domain · up to 3 approved sending services · written approval before changes

Reads public settings only. No mailbox password or login. It cannot identify every service that sends for you.

Is Shield a fit? For a business using its own email domain that needs help reviewing authentication across its mail platform and sending tools.

Shield does not investigate compromised accounts, stop lookalike domains or fake display names, build bulk cold-email infrastructure, or guarantee inbox placement. Verify payment requests through a separate trusted channel.

WHAT THE CHECK SEES AND SETUP VERIFIES

The free check reads records. Setup checks your sending services.

FREE PUBLIC CHECK

  • Reads public email records for your business domain.
  • Observes selected public signals on your website’s main page.
  • Uses no mailbox password or website administrator login.
  • Cannot find every sending service or confirm that your real messages pass the checks.

KOVA SHIELD SETUP · $750

  • Review: Up to three approved sending services and an exact change plan.
  • Approve: Written approval of the exact DNS changes before publication.
  • Verify: Check the included services after approved changes.
  • Handoff: A dated Shield Record with results and open items.

Your IT provider retains ownership and access. Shield prepares the agreed authentication work and records the checks alongside them.

ILLUSTRATIVE SCENARIO · EXAMPLE ONLYSAMPLE ARCHITECTURE

Illustrative Scenario: Multi-Sender Studio (Example Only)

Representative scenario showing how a typical multi-sender environment can be structured: an initial observation finds a monitoring-only policy (p=none) alongside billing mail that needs alignment review. During a staged setup after access and written approval, approved sending sources can be mapped, exact changes reviewed before publication, and the policy advanced only when the agreed checks support it. Actual results and open items are then recorded in the client handoff.

Example Scope: 1 Domain, Up to 3 Senders·Estimated setup: 3–7 business days after access and written approval; verification can extend timing.·Sample deliverable: dated Shield Record

STRAIGHT ANSWERS

What email authentication does and does not do.

Clear limits on the public check, the setup work, and what still belongs with your IT provider.

Read how Shield works →

A sending service is a tool or platform sending messages using your domain, such as Microsoft 365, a CRM or invoicing service—not each employee mailbox. We confirm the included services before work.

No. SPF, DKIM, and DMARC can help participating mail systems handle messages that pretend to come from your exact domain. They do not stop lookalike domains, compromised accounts, fake display names, or social engineering. Keep payment verification separate from email.

Your IT provider retains ownership and access. Shield handles the agreed sender inventory, proposed authentication changes, checks and record alongside them. Changes require written approval.

No. Shield checks authentication for the included sending services. Inbox placement also depends on reputation, content, recipient behavior, filtering, and sending practices.

An enforced DMARC policy can tell participating recipient systems to quarantine or reject mail that fails alignment. This reduces direct-domain spoofing risk. It does not stop lookalike domains, compromised accounts, or fake display names.

Estimated 3–7 business days after required access and written approvals. DNS propagation, third-party sender verification and observation may extend timing; this is not a promise of full DMARC enforcement in that window.

No passwords are needed for the initial public check. For implementation, your DNS administrator or IT provider can publish approved updates directly, or use a least-privileged access method that fits your process. Kova Shield should never require your mailbox password.

Start with the public check.

Baseline review scope and price are confirmed before work. An inquiry takes no payment and authorizes no DNS change or subscription.
