DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that helps prevent email spoofing and phishing attacks. DMARC Analyzer Open Source is a tool that allows users to analyze and visualize DMARC reports in a more human-friendly way. In this blog post, we will discuss the benefits of using DMARC Analyzer Open Source and how to use it.
What is Open Source DMARC Analyzer?
Open Source DMARC Analyzer (OSDA) is a tool that helps you analyze and visualize DMARC reports, which are used to track email authentication and prevent phishing attacks. It’s a software program freely available for anyone to use and modify, unlike paid, closed-source alternatives.
Here’s how it works:
- DMARC Reports: You set up DMARC (Domain-based Message Authentication, Reporting & Conformance) for your domain, and email providers send you reports about emails sent from your domain.
- Parsing: OSDA doesn’t directly work with raw DMARC reports. You need to use another tool like
rrdmarcordmarcts-report-parserto convert the reports into a format OSDA can understand. - Analysis & Visualization: OSDA takes the parsed reports and analyzes them, providing insights into various aspects like:
- Authentication: Are emails passing SPF and DKIM checks?
- Policy Enforcement: What happens to unauthenticated emails (quarantine, reject)?
- Phishing Attempts: Are there unauthorized senders trying to impersonate your domain?
- User-Friendly Output: OSDA presents the information in easy-to-understand charts and graphs, making it easier to identify issues and track progress.
Benefits of using OSDA:
- Cost-effective: Free to use and modify, saving you money compared to paid solutions.
- Transparency & Customization: You have full access to the code, allowing for customization and deeper analysis.
- Data Privacy: You keep your DMARC data on your own servers, ensuring privacy and control.
Popular OSDA options:
- Open DMARC Analyzer: A self-hosted solution with detailed reporting and visualizations.
- Parsedmarc: A command-line tool for parsing and analyzing DMARC reports.
- Dmarcian: A cloud-based platform with OSDA-like features, but with some paid options.
Choosing the right OSDA depends on your technical expertise, reporting needs, and comfort level with self-hosting software.
Benefits of Using DMARC Analyzer Open Source
There are several benefits of using DMARC Analyzer Open Source, including:
Total Visibility
DMARC Analyzer Open Source provides total visibility into multiple incoming and outgoing email channels. This allows users to examine the data more effectively and thus, detect phishing and malicious information early on, preventing the risk of cyberattacks and brand exploitation.
Customization
DMARC Analyzer Open Source can be customized to the needs of various sectors while maintaining security. This means that users can tailor the tool to their specific needs, making it more effective in detecting and preventing email spoofing and phishing attacks.
Security
DMARC Analyzer Open Source detects phishing and malicious information early on, preventing the risk of cyberattacks and brand exploitation. This is especially important for businesses that rely on email communication to conduct their operations.
Ease of Use
DMARC Analyzer Open Source makes the DMARC deployment process easier. It presents the DMARC report in user-friendly charts and graphs, allowing enterprises to examine the data more effectively and thus, detect phishing and malicious information early on.
How to Use DMARC Analyzer Open Source
To use DMARC Analyzer Open Source, follow these steps:
- Install parsedmarc, an open-source project hosted on Github.
- Use Elasticsearch and Kibana (or Splunk) to work as a self-hosted open-source alternative to commercial DMARC report processing services.
- Customize the DMARC report analyzer to the needs of various sectors while maintaining security.
- View a lot of information, including individual SPF and DKIM passage, as well as the final DMARC passage.
- See graphs over time to monitor how alignment changes over time, for example, after a policy or configuration change.
Best Open Source DMARC Analyzers
There are several open-source DMARC analyzers available that can help users analyze and visualize DMARC reports. Here are some of the best open-source DMARC analyzers:
Dmarcian
Dmarcian is one of the most trusted sources for all things DMARC. It has been around since 2012 and offers comprehensive tools and features to help teams with even the most advanced DMARC needs. Dmarcian’s tools are incredibly comprehensive and help teams with even the most advanced DMARC needs.
DMARC Digests
DMARC Digests is a newer DMARC service that was created with one goal in mind: building a tool that’s simpler and more intuitive than the rest of the pack. It’s easy to see if you’re having any DMARC issues, and if you do, DMARC Digests makes digging into their causes easy, too.
Parsedmarc
Parsedmarc is a Python module and CLI utility for parsing DMARC reports. When used with Elasticsearch and Kibana (or Splunk), it works as a self-hosted open-source alternative to commercial DMARC report processing services. Parsedmarc can parse reports from an inbox over IMAP, Microsoft Graph, or Gmail API, and it transparently handles gzip or zip compressed reports.
DMARC Report Analyzer
DMARC Report Analyzer is a free open-source DMARC report analyzer that presents the DMARC report in user-friendly charts and graphs, allowing enterprises to examine the data more effectively and thus, detect phishing and malicious information early on.
DomainAware Parsedmarc
DomainAware Parsedmarc is another open-source DMARC report analyzer and visualizer that works as a self-hosted open-source alternative to commercial DMARC report processing services. It can parse draft and 1.0 standard aggregate/rua reports, forensic/failure/ruf reports, and reports from an inbox over IMAP, Microsoft Graph, or Gmail API. It also transparently handles gzip or zip compressed reports and offers consistent data structures.
These open-source DMARC analyzers offer a range of features and benefits, including total visibility, customization, security, and ease of use. Users can choose the one that best suits their needs and preferences.
Conclusion
DMARC Analyzer Open Source is an open-source project hosted on Github that parses DMARC reports. It has many desirable features, such as viewing a lot of information, including individual SPF and DKIM passage, as well as the final DMARC passage. It also allows users to see graphs over time to monitor how alignment changes over time, for example, after a policy or configuration change. DMARC Analyzer Open Source provides total visibility into multiple incoming and outgoing email channels, can be customized to the needs of various sectors while maintaining security, and detects phishing and malicious information early on, preventing the risk of cyberattacks and brand exploitation.
