“Red Sift makes email security easy. I’ve done implementations for DMARC before and this was by far the easiest. They take away all the headaches and make it painless.”

"Red Sift is a leader in email security. It was a requirement for us to work with a service provider that had a proven track record of effectively protecting major organizations from unauthorized parties attempting to use their domain for spoofing."

“OnDMARC actually helped us discover and reject spoofing attacks we weren’t aware of.”

“With OnDMARC, we are able to scale and grow effectively as we add more employees and complete more acquisitions without worrying about shadow IT.”

“Red Sift’s managed SPF solution doesn’t require the use of macros making it fully compatible with global email systems, whilst removing the known SPF entry restrictions.”

“Red Sift protects the domains of 4 of the 5 magic circle law firms in the UK as well as international law firms. Their track record in the legal sector made them the obvious choice of cybersecurity vendor for William Fry.”

“The combination of compelling commercials, fantastic pre- and post-procurement support, and a genuine desire to help us succeed made Red Sift the clear choice for us. They’ve helped us strengthen our infrastructure, so Save the Children can focus on what matters most: protecting children and delivering life-changing support.”
