Red Sift named a 2026 G2 Best UK Software Company

We’ve got some news we’re proud to share: Red Sift has been named one of the Best UK Software Companies in G2’s 2026 Best Software Awards, driven by the exceptional customer feedback and market performance of Red Sift OnDMARC.

The G2 Best Software Awards celebrate the world's leading software companies and products based on authentic reviews from real users. To earn a place on this list, companies must have received at least 50 approved reviews during 2025, and the recognition is driven entirely by customer feedback, not marketing noise.

Being recognized on a UK-focused list carries particular weight for us. Red Sift was founded here, is headquartered here, and while we now support organizations globally, the UK is where our approach to cybersecurity was shaped. So yes, we’ll admit this award caused a very slight tremor in our otherwise stiff upper lip.

UK organizations have high expectations when it comes to email security, shaped in part by clear guidance from bodies such as the National Cyber Security Centre (NCSC). 

With email recognized as a primary attack vector, there’s a strong emphasis on getting authentication right and very little tolerance for disruption when making changes. 

So, seeing OnDMARC become a trusted choice across the UK tells us we’re solving a real problem, making DMARC implementation achievable without turning it into a drawn-out, high-risk project.

OnDMARC's strong performance in G2's Winter 2026 rankings—where we secured #1 rankings across Europe and EMEA—shows that this recognition isn't a one-off. It's part of a consistent pattern of customer satisfaction and market leadership.

Thanks to everyone who's been part of this journey, whether through detailed reviews, candid feedback, or simply trusting us to protect your email infrastructure.
