The Email Authentication Challenge

Email is the #1 way attackers target an organization’s customers and
email ecosystem. DMARC authentication, specifically with an enforcement
policy of Reject, is the single most effective way to close this vulnerability
inherent to email. While the premise of authentication is straightforward,
organizations can encounter roadblocks and challenges along the way to
an enforcement policy. These include:

The “many sender” problem: Email environments are often complex,
comprised of many domains associated with dozens of legitimate
senders, such as Salesforce and Marketo, along with many illegitimates
ones—spammers, cybercriminals, and others looking to profit from your
brand. Organizations need a painless way to understand and manage
the domains used by their email ecosystem, including their own internal
and third-party senders.

Ongoing configuration and record maintenance in DNS: The workflow
and configuration of DMARC authentication is intricately tied into legacy
DNS systems. In many organizations, access and change control around
DNS can be problematic. The frequency with authentication-related
records needing to be updated combined with the lack of robust error
handing within DNS itself often complicates and extends DMARC projects.

The cost of “doing it wrong”: Incorrectly configuring authentication can
lead to false positives, deliverability issues, and brand damage. Taking the
final step to a Reject policy can be a daunting prospect if the business
impact of undeliverable email is unknown or cannot be predicted.

This brief summarizes how the automation features and hosting options
with Agari Brand Protection™ solves these challenges.

The Agari Solution

Managing this kind of complexity requires powerful, smart tools that organize the various sender, brand, and infrastructure relationships for you. Whether you are creating your own SPF and DMARC records or having Agari host them, Agari’s automation features will get you to enforcement quickly.

Automation Features

Email Cloud Intelligence (ECI)

For many organizations, cloud-based email services such as Salesforce, Marketo, or Epsilon represent the majority of email sent to customers and partners. Getting visibility into these third parties is a must before organizations can protect customers from phishing attacks; but manually matching brands with IP address and domains is a long, arduous process and is not scalable.

How it Works: Email Cloud Intelligence identifies who is communicating with your customers using your brand. It provides one place to view and manage sender domains and unknown IP addresses. This, in turn, enables businesses to easily identify and authorize legitimate email communications and block malicious ones.

Benefit: Email Cloud Intelligence enables businesses to easily identify and authorize legitimate email communications, block malicious emails, and protect customers, partners, and employees from advanced email attacks. This, in turn, improves customer response to email campaigns and protects your brand.

EasySPF™

Sender Policy Framework (SPF) is one type of DNS entry that assures email from a sender is actually from that sender and it is a critically important component of DMARC integration. However getting to enforcement using a manual process is difficult, costly, and error-prone.

How it Works: On a per domain basis, Agari’s EasySPF enables enterprises to quickly and accurately inventory all of their senders and associate the approved ones with each domain.

Benefit: EasySPF automates the process of building SPF records, simplifying and accelerating the implementation of DMARC.

EasyDKIM™

DKIM is another authentication-oriented text record in DNS. DKIM, which leverages public keys and depends on alignment with pertinent details within the SPF record, verifies message integrity, ensuring that a message’s content has not changed from the moment the message left the initial mail server. As policies and selectors vary with different senders, DKIM can be hard to manage and keep updated.

How it Works: EasyDKIM solves the challenges around DKIM management by providing DKIM situational awareness and tracking tools, automated DKIM selectors detection for senders, and enabling key rotation best practices.

Benefit: Automatically monitor your current DKIM environment and quickly align your senders to stay in compliance with cybersecurity best practices.

Look-alike Domain Defense

Some phishing emails leverage the domains you own, such as YourCompany.com, but others come from domains that are not controlled by you, such as look-alike domains that closely resemble your own domains. To keep your brand and your customers safe you need to address both types of attacks when they occur. Note: Look-alike Domain Defense is only available with Agari Brand Protection.

How it Works: Look-alike Domain Defense uses real-time feeds to identify malicious domains impersonating your brand including cousin domains (e.g. Exannple.com) as well as unrelated malicious domains attacking your brand (e.g. Attack4Hire. com). This gives you the tangible data you need to perform remediation using your takedown vendor.

Benefit: Look-alike Domain Defense detects and disrupts email attacks from domains you don’t control, ensuring that your customer email channel stays trusted.

Hosting Features

There are often many hidden costs to managing SPF, DKIM, and DMARC services. However, choosing a hosted deployment with Agari eliminates these additional costs by providing 24/7/365 resources and support. Agari hosted solutions combined with Agari automation services enable proactive detection of SPF, DKIM, and DMARC with your legitimate senders and monitors any irregularities to ensure nothing impacts the productivity of your business. All Agari resources possess the required skill set for monitoring and administrating your DMARC solution without need for you to hire any additional resources.

Hosted SPF

Corporations often don’t have the time (or the expertise to) build and host their own SPF records as part of the email authentication process.

How it Works: When Agari hosts the SPF record we completely take over the DMARC authentication process for all senders, including third-party ones. This is an alternative to using EasySPF to build your own record. It is an optional feature and organizations who don’t want to be locked into a given vendor can host their own.

Benefit: Agari assumes the responsibility of creating and hosting the SPF record, which is a critical step in the DMARC enforcement process. This means with a simple DNS change, companies are relieved from the burden of doing it themselves and ensured that the job is done correctly.

Hosted DKIM

For those organizations who prefer a full-service implementation, they can turn over DKIM record management to Agari.

How it Works: As with SPF and DMARC records, organizations can choose to save the DNS management, infrastructure, and full-time employee costs related to authentication by taking the DKIM management out of their environments.

Benefit: Have Agari host your DKIM to avoid the hassle and risk of DNS record changes. Free your DNS and email administrators to focus on other more urgent matters.

Hosted DMARC

For those organizations who prefer a full-service implementation, they can turn over the DMARC record management to Agari.

How it Works: Organizations can use the Agari Hosted DMARC feature whether they have no DMARC record or have one that they are currently hosting themselves. The process is as easy as selecting the domains that currently lack a DMARC and clicking a button to have Agari host them. This feature may be paired with our new Hosted SPF feature to streamline authentication.

Benefit: Hosted DMARC simplifies the initial DMARC implementation process as well as streamlines sender updates as they occur.

Getting to Enforcement

Vendors often claim to offer automation and ease of DMARC implementation, but when one looks at the actual protection ratios, the truth emerges. Agari has more domains at reject than any other vendor. Organizations serious about blocking phishing shouldn’t settle for a vendor who has most of their customers stalled at or monitor-only mode.

The Agari Advantage

Agari analyzes 2 trillion emails per year claiming to be from your domains across the world’s largest cloud email providers. Agari combines its own third-party sender knowledge and automation with intelligence-fed tools that let you authenticate your organization’s legitimate email, blocking unauthorized emails from reaching your customers. Agari has brought more customer domains to a Reject policy than any other vendor. And when criminals switch tactics to employing look-alike or cousin domains, our Look-alike Domain Defense alerts you to these messages spoofing your brand and allows you to detect the malicious URLs so that you can disable the attack. Finally, Agari offers fully hosted authentication, enabling the fastest path to enforcement while freeing your in-house resources to work on other priorities.
