Across the portfolio

Six products on G2, three honest tiers

We frame the G2 picture honestly. DMARC Report is a Category Leader. Phish Protection and AutoSPF have strong cohorts of working operators. Outbound SMTP and NuReply are loved by the people who use them but smaller in volume. The framing is not aspirational; we publish what is actually true on the platform.

Category Leader

DMARC Report

Authenticate · 4.8 ★ on G2

Multi-region G2 Category Leader for DMARC Software. Leader globally and across EMEA, Europe, Asia, Asia-Pacific, and the Small Business segment. Hundreds of verified reviews from working DMARC operators.

Strong cohort

Phish Protection

Protect · 4.7 ★ on G2

Anti-phishing for Microsoft 365 and Exchange. Click-time URL inspection, BEC defense, impersonation detection. The reviews are from operators who picked us specifically against the enterprise gateways.

Strong cohort

AutoSPF

Authenticate · 4.8 ★ on G2

Automatic SPF management for organizations breaking the 10-DNS-lookup limit. Built because the only competing service quoted $1,000 per month for a customer paying us $4. Now runs for a $16 billion IT services firm.

Loved but niche

Outbound SMTP

Deliver · 4.7 ★ on G2

Operating since 2014. Free up to 1,000 emails per month. The reviews come from people who needed an SMTP relay that just works without an enterprise contract or a credit card.

Loved but niche

NuReply

Deliver · 4.7 ★ on G2

Bring-your-own-mailbox cold email outreach with built-in deliverability hygiene. Newer product on G2; the reviews so far come from operators who tried the heavy hitters first.

Why we publish this rollup

Earned, not bought

DuoCircle does not run a sales-led marketing budget. There is no SDR funnel buying ads to chase you down after a demo. The G2 reviews come from customers we took care of, who chose to leave a review on a third-party platform that does not let us influence the score.

The honest picture is that DMARC Report is the anchor of the recognition. The other products have smaller cohorts and we say so. We do not claim category leadership for products that have not earned the volume. The framing rule is the same one we use everywhere: tell people what is true so the relationship survives the work.

If you want to verify any of this, the links above all go to G2 directly. Read the reviews. Read the dissents. The picture you get there is the picture that runs the company.
