Most DMARC tools show you what's passing or failing authentication. DMARCeye tells you what to do about it. The platform converts raw DMARC XML reports into plain-language, domain-specific guidance that helps teams at any technical level identify every source sending mail on their behalf, and move safely from monitoring to full enforcement without disrupting legitimate email flow. At the core of DMARCeye is its AI-powered report analyzer, which continuously processes SPF, DKIM, and DMARC alignment data to surface authentication gaps, misconfigurations, and suspicious activity. Instead of leaving users to interpret complex aggregate reports, the platform generates contextual, actionable next steps tailored to each domain's specific configuration and risk profile. This guidance-based approach directly addresses one of the most persistent problems in email security: 43.7% of monitored domains remain stuck at p=none (monitor-only) and never reach full enforcement (our data). Key capabilities include real-time DMARC reporting and dashboards, smart alerting that cuts through noise to flag only what matters, DMARC policy management with safe enforcement progression, blacklist monitoring, IP reputation tracking, and an MCP (Model Context Protocol) server that lets teams connect their DMARC data directly to AI assistants like ChatGPT, so they can simply ask questions, then act. DMARCeye is designed to be lightweight and focused, so it won't overlap with your existing email stack. Pricing starts at $4 per domain per month, with a free plan for single-domain monitoring and custom enterprise pricing available. It scales from freelancers and small businesses protecting a single domain all the way to enterprises and digital agencies managing dozens of domains across brands, regions, or client accounts. Trusted by 2,000+ companies worldwide, DMARCeye is the practical choice for teams that need a tool that actually gets them to enforcement. **Average Rating:** 4.8/5.0 **Total Reviews:** 3 #### How Do G2 Users Rate DMARCeye? - **Ease of Use:** 9.4/10 (Category avg: 9.3/10) - **DMARC Alignment:** 10.0/10 (Category avg: 9.5/10) - **Threat Identifications:** 9.4/10 (Category avg: 9.3/10) - **Analytics:** 9.4/10 (Category avg: 9.3/10) #### Who Is the Company Behind DMARCeye? - **Seller:** [DMARCeye](https://www.g2.com/sellers/dmarceye) - **Year Founded:** 2024 - **HQ Location:** Prague, Czech - **Twitter:** @dmarceye 12 Twitter followers - **LinkedIn® Page:** [www.linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=935365fc2d1cd498d823d40e57f3dacb773ee8215b9b566c92718b9608685126&secure%5Burl%5D=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2Fdmarceye%2F&secure%5Burl_type%5D=linkedin_company_website) 1 employees on LinkedIn® #### Who Uses This Product? - **Company Size:** 67% Small, 33% Medium #### What Do G2 Reviewers Say About DMARCeye? _AI-generated summary from verified user reviews_ ##### Pros - Users appreciate the **clarity of DMARC reporting** in DMARCeye, making authentication issues easy to understand and address. - Users appreciate the **clear and intuitive dashboard** of DMARCeye, making DMARC reporting easy to understand. - Users value the **clear and understandable DMARC reporting** of DMARCeye, simplifying the management of authentication issues. - Users value the **deliverability improvement** of DMARCeye, benefiting from detailed insights and smart alerts for better email management. - Users appreciate the **easy integrations** of DMARCeye, enhancing their ability to analyze email reports efficiently. ##### Cons - Users find it frustrating that they cannot **manage their DNS directly** from DMARCeye, limiting their control. - Users are frustrated with the inability to **manage DNS directly** from DMARCeye, complicating their setup process. #### What Are Recent G2 Reviews of DMARCeye? **["Easy DMARC Reporting with Clear and Actionable Dashboards"](https://www.g2.com/survey_responses/dmarceye-review-12075830)** **Rating:** 5.0/5.0 stars _— Jack R._ [Read full review](https://www.g2.com/survey_responses/dmarceye-review-12075830) **["Easy setup and clear reporting for each domain"](https://www.g2.com/survey_responses/dmarceye-review-11656645)** **Rating:** 5.0/5.0 stars _— Jakub P._ [Read full review](https://www.g2.com/survey_responses/dmarceye-review-11656645) ### [DMARCguard](https://www.g2.com/products/dmarcguard/reviews) DMARC Monitoring and Email Authentication Solution, Supporting all the 9 Protocols of Email Including DMARC, DKIM, SPF, MTA-STS, TLSRPT, BIMI, ARF, ARC, DANE.

Websites rely on third-party scripts, tag managers, analytics tools, payment services, and other external code that executes outside direct organizational control. That code can change at any time, creating a hidden attack surface that most traditional security tools fail to monitor because they focus on servers and infrastructure rather than runtime browser behaviour. Report URI closes that gap. Built specifically for client-side security, Report URI helps security and engineering teams see what executes in the browser in real time, detect changes in third-party code as they happen, and enforce precise, policy-driven controls using browser-native standards like Content Security Policy (CSP). Unlike solutions that rely on injected scripts, proxies, or simulated behaviour, Report URI takes a browser-native approach. Organizations can monitor and enforce policies at the point of execution without adding agents, impacting site performance, or introducing additional operational risk. Teams use Report URI to: ● Identify unauthorized or unexpected scripts ● Reduce risk from third-party code and supply chain attacks ● Support PCI DSS 4.01 compliance initiatives including 6.4.3 and 11.6.1 ● Protect sensitive browser-based workflows including login, checkout, and authentication flows ● Enforce runtime security policies with precision ● Demonstrate security posture with audit-ready evidence Report URI is designed to deliver immediate value without requiring major infrastructure changes.

Email authentication isn't a one-time setup. Authex gives teams continuous visibility across all six protocols, actionable insights from real DMARC report data, and a controlled path from monitoring to full enforcement. How It Works Organizations start with a domain scan to understand protocol coverage, configuration gaps, and current exposure. Domains are then brought into Authex for continuous monitoring of DNS state, report data, deliverability signals, and mail-security findings. From there, guided recommendations, validation workflows, and approval controls help teams move toward stronger policy with less operational risk. Autonomous Agent The Authex agent monitors DNS records and aggregate reports continuously, evaluates compliance over time, and recommends the next safest action for each domain. It runs 27 deterministic rules covering DMARC enforcement progression, SPF hygiene, DKIM key rotation, MTA-STS upgrades, TLS-RPT monitoring, and blacklist response. Every action includes a before/after preview, risk assessment, and full rollback capability. Start in monitor mode, review suggested fixes, or allow automatic low-risk changes while keeping higher-risk decisions under your control. Operational Depth Authex connects the workflows that security, IT, and domain owners typically handle across separate tools: - Aggregate reports, failure reports, and TLS reports provide the visibility needed to understand sending behavior, investigate authentication failures, and monitor transport-security outcomes. - Domain scanning, tagged test messages, authentication verification, inbox placement testing, and blacklist monitoring across 80+ DNSBLs with contextual attribution. - Microsoft 365 mail-security auditing with read-only access to identify policy weaknesses affecting both protection and deliverability. - Rule-based alerts for DNS changes, compliance drops, new threats, phase transitions, and completed agent actions. Managed Services Authex provides fully managed versions of all six protocols. OneSPF handles SPF flattening with automatic updates when upstream providers change IP ranges. Managed DKIM supports automatic selector detection across major providers. Managed MTA-STS and TLS-RPT handle transport-layer security configuration. Benchmark Intelligence Authex is informed by The Index, a benchmark dataset tracking email authentication posture across hundreds of thousands of domains. The Index organizes results by country, TLD, sector, and provider so teams can compare their posture against the broader ecosystem. Compliance Authex helps organizations monitor and improve posture against Google and Yahoo bulk-sender rules, PCI DSS 4.0, NIST SP 800-177 guidance, and DORA requirements. Pricing DIY: $15 per domain/month. Your team manages DNS publishing, reviews recommendations, and controls enforcement decisions. Managed: $99 per domain/month. Authex handles protocol setup, publishing, SPF upkeep, and safe progression toward stronger enforcement. Both plans include full platform access, all six protocols, the autonomous agent, reports and alerts, deliverability and blacklist monitoring, The Index access, and unlimited team members. 14-day free trial on DIY. #### Who Is the Company Behind Authex Labs? - **Seller:** [Authex Labs](https://www.g2.com/sellers/authex-labs) - **HQ Location:** Newark, US - **LinkedIn® Page:** [linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=35c4934385138ac6909985aabcdd9af5d869b5233bf074a1b013eb4b15049573&secure%5Burl%5D=https%3A%2F%2Flinkedin.com%2Fcompany%2Fauthexlabs%2F&secure%5Burl_type%5D=linkedin_company_website) 1 employees on LinkedIn® ### [DMARC Dashboard](https://www.g2.com/products/dmarc-dashboard/reviews) DMARC Dashboard by DmarcDkim.com is an anti-spoofing and domain protection solution in the email security software category that helps users implement, manage, and monitor DMARC, DKIM, and SPF records to prevent email impersonation, phishing, and spoofing attacks.
