The service

What anti-phishing from DGo includes

For B2B SaaS and tech teams, anti-phishing from DGo checks and fixes SPF, DKIM and DMARC on every domain you send from, moves DMARC to enforcement in stages without breaking legitimate mail, and sets alerts for newly registered lookalikes of your domain. For the records involved, read our corporate DNS guide.

Sound familiar?

Where email trust usually breaks

Three patterns that often show up before a phishing email reaches a customer. Each one has a clear first fix.

Lookalikes

Invoices sent from a lookalike domain

A domain one letter off from yours fooled a customer’s finance team.

Senders

Nobody knows who sends mail as you

Marketing tools, CRMs and old vendors all send email as your domain.

Policy

DMARC stuck on monitoring only

Reports arrive, nobody reads them, and spoofed mail is never blocked.

How it works

Find every sender, then enforce

Stricter DMARC policies wait until every legitimate sender passes, so no customer email goes missing on the way.

01

Check

SPF, DKIM, DMARC and lookalike registrations checked from public records.

02

Enforce

DMARC moved from monitoring to quarantine, then reject, in agreed stages.

03

Watch

Alerts for new lookalike domains, each one checked, with a route to report it.

What you get

Proof, honestly

Who does the work, and what you get

DGo has no client case studies yet, so here is what you can check for yourself.

Your engagement lead

A senior DGo strategist leads every engagement

One strategist from the diagnostic to the last report, and your single point of contact. The proposal names your strategist, with their background, before you sign. Specialist work goes to partners, named in the proposal too.

  • Read-only access first, named users only
  • Fixed scope and timeline in the proposal
  • A written report on a fixed day each week
  • The accounts and data stay in your name

Takedowns and incident response

DGo does not do legal takedowns or incident response. Specialist work goes to partners, and we name them in the proposal before you sign.

Fit check

Who this is for, and who it is not

A good fit if you

  • Good fit: Send invoices, quotes or contracts by email
  • Good fit: Use several tools that send as your domain
  • Good fit: Want DMARC enforced without lost mail

Probably not a fit if you

  • Not a fit: Have an active incident to stop today
  • Not a fit: Want an email security gateway installed
  • Not a fit: Want phishing tests run on your staff

FAQ

Questions about anti-phishing

Not if it is rolled out in stages. DMARC reports come first, so every legitimate sender is found and fixed before a stricter policy applies. Each step, from monitoring to quarantine to reject, is agreed with whoever manages your email. Much of the work is finding the tools that send as you, such as a CRM, billing tool or support desk.
