More About Agari

Agari focuses on securing enterprise email communications against phishing, BEC, and identity-based threats. Its offerings are designed for organizations that operate cloud-hosted or hybrid email environments and need to protect users, partners, and customers from spoofed domains and socially engineered attacks. The company’s technology is typically deployed in conjunction with existing secure email gateways, cloud email platforms, and identity systems to extend defense beyond traditional spam and malware filtering.

A central element of Agari’s approach is domain-based email authentication. Its solutions support protocols such as Domain-based Message Authentication, Reporting and Conformance (DMARC), Sender Policy Framework (SPF), and DomainKeys Identified Mail (DKIM) (email authentication). These protocols enable domain owners to validate authorized sending infrastructure, cryptographically sign messages, and publish policies that instruct receiving mail servers how to handle messages that fail authentication. Agari provides tooling to simplify implementation of these standards at scale, including configuration assistance, policy testing, and monitoring capabilities.

In addition to protocol enforcement, Agari applies behavioral analytics and sender reputation models (threat detection) to distinguish between legitimate business communications and malicious campaigns. Its technology evaluates factors such as sending history, relationship graphs, and content attributes to identify impersonation attempts, account takeover activity, and fraudulent messages that may pass basic authentication checks. This focus on identity and behavior supports detection of social engineering attacks that rely on trusted identities, including spoofed executives, suppliers, or brands.

From an architectural standpoint, Agari’s offerings integrate with enterprise email infrastructures through APIs, mail flow controls, and policy-based routing. Deployments are typically cloud-delivered, allowing organizations to process email traffic without deploying hardware appliances. The platform is built to operate across multi-domain environments and to provide centralized visibility into authentication status, threat activity, and policy outcomes for Security Operations (SecOps) teams.

Within an enterprise IT directory, Agari aligns with categories such as email security, email authentication, and anti-phishing protection. It is relevant for SecOps centers, identity and access management teams, and infrastructure groups responsible for corporate email and domain management. Organizations commonly use Agari to implement DMARC in enforcement mode, protect brand domains from spoofing, and reduce the volume of targeted email attacks reaching end users, while maintaining compatibility with existing email and security stacks.
