Questec builds practical email-security tooling that helps organizations of every size deploy DMARC, SPF, and DKIM correctly — protecting their domains from phishing, spoofing, and brand abuse.
Explore desi-DMARC Get in TouchEmail remains the #1 attack vector. We make the standards that defend it — DMARC, SPF, DKIM — accessible, understandable, and actually deployable.
Deep inspection of your domain's email-authentication posture — SPF records, DKIM selectors, DMARC policies, and the misconfigurations attackers love to exploit.
Aggregate and forensic DMARC reports turned into clear, human-readable dashboards, so you know exactly who is sending mail as your domain.
A safe, step-by-step path from p=none to p=reject — without breaking legitimate mail from your marketing tools, CRMs, and workflows.
Our flagship product — a DMARC monitoring and enforcement platform built for teams that want enterprise-grade email protection without enterprise-grade complexity or pricing.
Questec is an early-stage security startup on a mission to make email authentication universal. Despite DMARC being an open standard for over a decade, the vast majority of domains worldwide remain unprotected or stuck at monitoring-only policies — leaving them open to impersonation.
We believe the barrier isn't the standard — it's the tooling. Existing solutions are either too complex, too expensive, or both. We're changing that, starting with markets that have been underserved by incumbent vendors.
Questions, partnerships, or early access to desi-DMARC — we'd love to hear from you.
