Red Sift named a Top 50 company in 2025 Emerging Stars Awards

We’re pleased to share that Red Sift has been named Best Performing Company – Security & Infrastructure in the 2025 Emerging Stars Awards. These awards, part of the Megabuyte100 series, recognise the UK’s 50 best-performing scale-up technology companies based on solid financial performance, from over 800 entries. 

Being recognised in this category reflects the consistent progress we make at Red Sift – driven by a focus on product innovation, seamless platform integration, industry accreditations, and a growing enterprise customer base.

Continued innovation to drive success

This award highlights the impact of the Red Sift Pulse Platform in helping organisations strengthen their cybersecurity. Over the past year, we’ve expanded globally, launched our Large Language Model (LLM) assistant, Red Sift Radar, and added new capabilities across our portfolio, helping to support thousands of businesses in reducing risk, stopping phishing, and protecting their brands online. We’re proud to be consistently recognised as a G2 Leader—backed by reviews from the customers who rely on us every day.

“2025 is off to a strong start and I’m pleased that Red Sift has been named Best Performing Company in the Security & Infrastructure category. It’s a proud moment for our team, and we’re grateful to Megabuyte for spotlighting the hard work behind our growth”.

We also remain committed to adapting and responding to emerging threats. Following last year’s SubdoMailing attacks, we announced DNS Guardian, giving organisations real-time visibility and control over their DNS infrastructure, helping detect misconfigurations and prevent DNS hijacking before it becomes a threat. 

Scaling for growth

As we look ahead in 2025, we’re scaling our product and engineering efforts to meet the evolving needs of our customers. From defending against phishing and spoofing to simplifying email authentication, we’re focused on building practical tools that help businesses stay secure. 

Our long-term goal remains the same: Building a fundamentally safer internet for all.
