The proof is in the results: Phishing attacks of just one type - the business email compromise (BEC) - have caused at least $26 billion in losses in the past five years alone, according to the FBI. Such AI/ML techniques simply aren’t suited to deal with a rapidly mutating attack profile. Unfortunately, despite the advances in artificial intelligence and machine learning (AI/ML), defensive strategies have not been able to keep up.

Verify email sender identity how to#
The problem is that attackers have learned how to get through email security at all three defensive layers currently in use by most organizations: the gateway, the mail client, and the end-user.Īttackers evade the secure email gateway by outsmarting AI/ML engines: “Urgent” invoices from trusted “business partners” contain misleading bank information for wire transfers. Emails from “your CEO” ask for gift card donations to a charity. A message from an unknown sender appears as a personal note from one of your friends. One campaign hijacks the World Health Organization’s identity and offers dubious tips and dangerous links to COVID-19 resources. Phishing attacks are increasingly mutating fast, shifting tactics and lures constantly. This is why it’s so critical to verify that the emails that land in your inbox are trustworthy and safe. This is an environment where workers are more distracted and using less-secure networks and hardware.

It’s used for account activation, service registration, password resets, invoicing, purchase verification, opt-in confirmations, loyalty clubs, and identity verification.Īdding to risk factors is the fact that a record number of employees are working from home. It’s an essential line of communication for one-on-one and group conversations, both business-to-business and business-to-consumer. Why? Email is at the heart of everything we do online. Despite massive advancements in perimeter and endpoint defenses, email remains a cybersecurity weak link for many companies.

Receivers verify the Purported Responsible Address (PRA) against the information stored in DNS to reject unauthorized messages. Authentication Resourcesĭomain owners must identify their sending mail servers by IP Address in new DNS records. To use the tool, simply send an email from the domain you want to test to You will receive a return email containing an analysis of the authentication status of the message you sent. The tool allows you to check the format of any DKIM, DomainKey, SenderID or SPF records published by your domain and to see the result of these authentication checks on any message you send. To encourage adoption by ALL senders, The ESPC has partnered with ESPC member Port25 to provide this testing tool.
In fact, adoption of email authentication is mandatory for ESPC members. The ESPC feels that email authentication is critical for establishing and maintaining email credibility and accountability.
