Red Sift’s cloud-based applications protect against email threats with DMARC and AI. 

No matter how many training sessions are delivered or company reminders sent out, there’s always a chance that one of your employees will click on a dangerous phishing link. One distracted moment is all it takes to activate malicious software or initiate a full-fledged attack on your enterprise.

The risk is real. Phishing scams aimed at tricking employees into sharing sensitive information are growing more sophisticated. Blanket spam attacks of generic emails to large groups have evolved into spear phishing schemes—highly targeted attacks on individuals in which hackers impersonate a trusted source—be it a friend, a boss, or a bank.

Attackers exploit moments of uncertainty, using convincing lures that promise financial relief, urgent updates, or critical guidance. Paired with the rise of AI-driven brand impersonation, distinguishing legitimate communications from malicious ones has become almost impossible.

Educating employees on how to spot the signs of an attack remains vital, but with modern technology advancements, it is no longer enough.  Red Sift’s mission is to make the internet a fundamentally safer place. Their technology offers enterprise organizations best-in-class defense against email security and brand impersonation attempts.

Automating cybersecurity

Red Sift was started in 2015 with the idea of creating an open platform to automate core cybersecurity processes. They’re big believers in technology streamlining workflows for security teams. A human analyst might spend hours combing through log files to contextualize incidents and understand intent; their AI-powered software-as-a-service offerings do it for them.  

Red Sift’s cloud-based applications protect against advanced threats—the type of standard email security appliances won’t catch. Red Sift OnDMARC stops unauthorized use of an organization’s email sending domains in just 6-8 weeks. Together with their advanced LLM Red Sift Radar, OnDMARC protects against phishing, business email compromise (BEC) and spoofing attempts.

In addition to protecting the inbox, Red Sift also offers applications focused on domain and social media protection via Red Sift Brand Trust, certificate monitoring and inventory with Red Sift Certificates, and full attack surface management through Red Sift ASM.

The need for cybersecurity spans the globe and industries, and their customers reflect that diversity. Many of the industries they serve—such as international telecom companies, banks, media organizations, retail, law, and government entities with complex supply chains—deal with highly sensitive information.

A robust, resilient cloud infrastructure

When Red Sift began developing their platform, they knew they needed a large amount of compute and memory and the ability to store vast quantities of data. And they wanted to create and operate the platform cost-effectively so they could pass the savings on to their customers.

Red Sift found IBM could provide them with the cloud-based IT infrastructure they needed through its Startup with IBM program, a short-term initiative for startups. They built most of their services from the ground up on a container-first microservices architecture. With IBM Bare Metal Servers as the foundation, they’ve added their own Kubernetes deployment in addition to the IBM Cloud Kubernetes Service.

Using bare metal machines gives them a large amount of compute that functions exactly as expected—they don’t have to be concerned about unusual occurrences when running their services. By using Kubernetes and containers, they also experience the benefits of virtual machines. Ultimately, they get the best of both worlds.

The level of service and support they’ve received from IBM has been very helpful. And as their needs have grown more sophisticated, the resilience of the IBM infrastructure has allowed them to meet their service level agreements, even with high-demand customers.

Although they’re a relatively young company, Red Sift has established an exceptional external security framework and are compliant with the ISO 27001 global security standard for developing, hosting, maintaining, and supporting their solutions. IBM’s compliance with the standard greatly simplifies their auditing processes.

In fact, IBM Cloud Object Storage is crucial to meeting our business continuity compliance requirements because it allows them to perform online backups that are quickly retrievable in the event of a catastrophic infrastructure failure.

Gearing up for next-generation security

Red Sift has had a high degree of success over the years and continues to expand their offerings. In December 2025, they were awarded first place across 8 of G2’s winter rankings, where they hold a score of 4.9/5. From an infrastructure perspective, they’ve been scaling up significantly and are now providing high levels of availability and low latency to large enterprise clients.

They continue to see an uptick in cyberattacks, especially with the recent upsurge in AI-related scams. As a result of this, many companies are accelerating plans to move toward next-generation security. This includes using AI to fight AI. Red Sift is eagerly looking forward to continuing to work with IBM as they develop and grow their portfolio of cybersecurity applications.
