Abnormal Security is an AI-native email security platform that deeply understands human behavior to stop advanced inbound email attacks—including business email compromise, vendor fraud, and credential phishing—as well as email account compromises and posture misconfigurations.

Email is the biggest threat vector in organizations today. Not only is it the broadest and easiest way for attackers to engage with their targets, it also exposes a major vulnerability: human behavior. Humans inherently trust their digital communications, which is then exploited by attackers through social engineering.

Unfortunately, modern trends are only worsening this human vulnerability. For instance, as generative AI tools like ChatGPT proliferated last year, cybercriminals have weaponized them to launch highly targeted email attacks that are costing businesses millions of dollars. And with the interconnected nature of cloud email, access to a single account can provide a way to access other applications across the enterprise.

Traditional secure email gateways (SEGs) struggle to stop these advanced attacks because they are designed to detect known indicators of compromise, like malicious attachments and suspicious links. And cybercriminals have figured out how to bypass these legacy solutions simply by sending text-based, socially-engineered emails that omit traditional indicators of compromise and appear legitimate.

Abnormal provides a modern solution to this human vulnerability in email security. Instead of looking for known-bad behavior, it uses an AI-native and API-based architecture to baseline known-good behavior across the email environment and then detects attacks based on anomalous activity.

As a result of this approach, Abnormal:
– Installs in 60 seconds via API
– Remediates malicious emails in milliseconds
– Reduces the time security teams spend on email security by 95%
– Reduces the number of costly email attacks by 4x
– Provides an extra two days of productivity per employee each year
– Has allowed 70% of customers to replace their costly SEGs with Abnormal

How we are different

1) Abnormal is pioneering AI-native cybersecurity. It is the only cloud email security solution that uses behavioral AI to detect advanced attacks with high precision. This is more important now than ever before, as malicious AI becomes a growing threat, with bad actors exploiting generative AI to launch sophisticated attacks. By using good AI to fight bad AI, Abnormal is resolving this conflict for every one of our customers, every day.

2) Abnormal has demonstrated extraordinary product strength. In the last year alone, it launched several new products, features, and integrations that provide customers with stronger protection against the shifting threat landscape – from collaboration app attacks and AI-generated attacks, to quishing attacks, and more.

Abnormal’s unique behavioral AI approach to email security, and the innovations it continues to make to its platform, have resulted in exceptional value for customers.

Abnormal reduces the number of email threats by ~4x, finds at least one compromised email account upon integration in 79% of Fortune 1000 deployments, and has detected potentially devastating attacks, including one $36M vendor fraud attack. According to Forrester, the average 10,000-employee organization that deploys Abnormal achieves a total ROI of 278%, prevents $4M dollars in losses due to business email compromise, and reduces SOC analyst hours spent on email security tasks by 95%.

Customers recognize this value, granting Abnormal a 99% “Would Recommend” rating on Gartner Peer Insights and securing the company Gartner’s Customers’ Choice Award for Email Security.

3) Abnormal is experiencing incredible growth. In just five years, it has secured 2,000+ customers, including more than 15% of the Fortune 500. Last July, Abnormal hit $100M ARR in only four years – making it the second fastest-growing cybersecurity company ever, behind only Wiz – and is continuing to grow more than 100% year over year.
