What their customers say

Quotes from people at Red Sift's customers.

“As an IT specialist, it's straightforward to set up DMARC on your own but something else entirely to look at the reports. Having OnDMARC’s interface to understand the reports is crucial. Seeing exactly what to do with an email that isn’t compliant makes it so much easier to implement DMARC successfully.”

Christian Arpino · Head of Engineering · Options IT

“less skilled IT people can update protocols through the OnDMARC panel without having to figure out the DNS themselves.”

Christian Arpino · Head of Engineering · Options IT

“Dynamic SPF is excellent. Overcoming the lookup limit is important but an error-prone and fiddly task without a service like OnDMARC. With Dynamic SPF, the complication and manual work is removed. It’s hugely beneficial.”

Christian Arpino · Head of Engineering · Options IT

“I’m excited about what this offering means for our clients. Providing a DMARC solution is a no-brainer, and ultimately Red Sift OnDMARC makes us a better MSP.”

Christian Arpino · Head of Engineering · Options IT

“DMARC should be a default part of what an MSP offers, regardless of the industry they serve. Spoofing and phishing attacks affect everyone. For the financial services industry though, where due diligence checklists are expected by investors and audits are completed by compliance bodies, it becomes even more important.”

“OnDMARC is incredibly straightforward to set up. The interface is so intuitive that new users are comfortable straight away”

Christian Arpino · Head of Engineering · Options IT

“Red Sift OnDMARC should be part of any good MSP’s cybersecurity stack.”

Christian Arpino · Head of Engineering · Options IT

“We were very clear in what we were looking for in a DMARC partner: we needed a cost-efficient solution that didn’t skimp on usability or effectiveness. We were particularly impressed by the level of support offered by OnDMARC’s support team, and once we had completed the free trial, it was clear we’d found the product to match our requirements.”

Nick Kenyon · Head of Operations · Numed

“the team is so responsive and proactive in reaching out to check-in and move us along. The support has been great - they are always there to lend a helping hand.”

Matthew Liacos · Systems Engineer · New England Biolabs

“The IT team at NEB are not messaging and email gurus, however, the Investigate tool ensures that that is not an obstacle. With this tool, we are able to validate each action taken inside OnDMARC by simply sending an email to the Investigate inbox. We then receive a quick and easy-to-digest report card letting us know whether the different email protocols have passed or failed. This saves me a ton of time.”

Matthew Liacos · Systems Engineer · New England Biolabs

“Given the small size of our IT team, we needed to find a solution we could easily manage without it being too time-consuming once implemented.”

Matthew Liacos · Systems Engineer · New England Biolabs

“We’re no longer chasing issues. With Red Sift, we’re running a security program that’s designed to stay ahead.”

Zain Ahmed · Lead Cloud and Infrastructure Engineer · Lhasa Limited

“If a message fails, I can ask Radar what happened and get a clear, actionable explanation. It’s saved me hours I used to spend manually troubleshooting.”

Zain Ahmed · Lead Cloud and Infrastructure Engineer · Lhasa Limited

“OnDMARC gave us a clear path to achieving DMARC enforcement. We now have a complete picture of what’s sending on our behalf, and we can onboard new services with full confidence.”

Zain Ahmed · Lead Cloud and Infrastructure Engineer · Lhasa Limited

“Red Sift offers the kind of granular insight and usability that’s essential in a security tool. With OnDMARC, I can see exactly where our policies are effective and where they need improvement, which lets us focus on high-priority issues,” the Sr. Systems Administrator concluded. “In comparison to Agari, Red Sift allows you to take a deeper dive into how email is functioning across each individual domain, giving us the insights we need to stay secure and compliant as we grow.”

Sr. Systems Administrator

“When I’m training other people on my team, I’m explaining where the benefits are rather than the quirks. When Agari was in the mix, I was explaining where all the quirks were,”

Sr. Systems Administrator

“As we transferred over SPF and DMARC policies, we discovered several domains with misidentified sources. We assumed emails were being delivered, but they were actually being quarantined. OnDMARC’s reporting flagged this right away, while Agari’s reporting had buried it in the details.”

Sr. Systems Administrator

“The ability to customize, filter, and view our data in different ways has been a game-changer. Whether I'm examining DMARC records, email sources, or specific configuration alerts, I can quickly apply or create custom filters for deeper insights,” he shared. “By contrast, Agari’s interface felt static and cumbersome, lacking the ability to inspect our data from different viewpoints.”

Sr. Systems Administrator

“Of the three other companies I considered, Red Sift stood out as the only solution with a truly unified interface. With Agari, it felt like a collection of different tools patched together in one place - functional, but disjointed. Red Sift, on the other hand, brought everything together seamlessly in one cohesive view.”

Sr. Systems Administrator

“Red Sift’s support felt like an extension of our team—something we didn’t experience with Agari.”

Sr. Systems Administrator

“The diligence and support of the whole OnDMARC team has been second to none. Not only have they got back to us really quickly, they’ve usually seen it before and have an answer. I’ve never felt like I had to do this on my own.”

Grant Currie · Business Analyst · ITV

“Being able to tell the CEO we blocked over 300,000 illegitimate emails over the summer was a great win for our team and, of course, the company’s reputation.”

CTO

“Nothing has compared to OnDMARC—its clear visual breakdowns, historical reporting, and ability to drill into senders and receiving domains have given us far better insight into where our emails are coming from.”

CTO

“This tool was fundamental. We used Investigate as proof to heads of department that we could safely implement DMARC and SPF without blocking any legitimate business emails.”

CTO

“Unlike other DMARC reporting tools, OnDMARC offered an intuitive interface with clear insight into what is aligned or not aligned for SPF for each service using our domain. This kept us on track and allowed us to get the job done effectively.”

CTO

“With OnDMARC, we have full visibility into and control over our enterprise email configuration,” summarizes James. “At a strategic level, we are confident in Red Sift as the cybersecurity vendor that will scale with us as we expand globally, grow into new markets, and complete acquisitions. That’s priceless.”

James Gray · Holland & Barrett

“It was important to have a solution that was easy to implement and had an amazing user interface. For example, SPF record management can get unwieldy, but the OnDMARC portal sets it out intuitively and makes it easy to manage.”

Holland & Barrett

“Service is outstanding, response times are great, and their engineers are always on call - Red Sift Customer Success is a pleasure.”

Holland & Barrett

“They make protocol deployment look easy!”

Holland & Barrett

“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.”

James Gray · Senior Infrastructure Manager · Holland & Barrett
