LibraCyber LetsDMARC

Take control of your email reputation and secure the delivery of your messages with DMARC. LibraCyber LetsDMARC is the best way to prevent cybercriminals from impersonating your domains and sending fraudulent emails to your business partners, employees, and customers. It identifies and authenticates valid senders – such as the email marketing, CRM, HR, and other third-party services you use – and blocks unauthorized use of your brand. DMARC is a protocol that protects domains from unauthorized use, indicating messages are protected by SPF and/or DKIM, and telling a receiver whether to junk or reject failing messages. LibraCyber LetsDMARC makes it simple to set up DMARC. You don’t need DNS expertise – just follow the prompts and explanations on-screen to configure and manage your DMARC, DKIM and SPF settings. Reporting is delivered as accessible and meaningful dashboards and summaries, so you can see what’s happening at a glance, and drill down into deeper detail as you need it. LetsDMARC guides you through the data and recommends any actions you should take if they’re needed.

Report URI

Report URI is a client-side security platform that helps organizations see what executes in users’ browsers, control what’s allowed to run, and prove it with auditable data. 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. Organizations can gain visibility quickly, move from passive monitoring to active control, and strengthen their client-side security posture without disrupting existing workflows. Know what executes. Control what’s allowed. Prove it.

Authex

Authex is an email authentication platform that helps organizations monitor, validate, and enforce DMARC, SPF, DKIM, BIMI, MTA-STS, and TLS-RPT across all their domains. 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.

Dmarc Busta

DMARC Busta is an autonomous DMARC enforcement platform built for teams that want their domains actually protected, not just monitored. Most DMARC tools collect aggregate reports, draw charts, and leave you to interpret XML and hand-edit DNS. DMARC Busta closes that gap: its Autopilot analyses report data, identifies every legitimate sending source, and writes the real DNS records for you, progressing each domain from p=none through p=quarantine to p=reject on a safe, staged schedule with automatic rollback if legitimate mail is ever put at risk. Setup takes minutes. Connect a domain and DMARC Busta instantly scans your existing SPF, DKIM and DMARC records and maps every active sender. You get a plain-English breakdown of misconfigurations, unauthorised senders and recommended fixes, with one-click approvals. From there you can apply changes manually using guided DNS tools, or hand the work to Autopilot for continuous, hands-free enforcement and 24/7 monitoring. Core capabilities include full DMARC, SPF and DKIM management, hosted SPF with lookup-limit handling to avoid the ten-lookup ceiling, hosted MTA-STS and TLS-RPT, aggregate report analysis with sender identification, forensic reporting, and instant email alerts when suspicious activity or a compliance regression is detected. Native integrations with Cloudflare, cPanel/WHM, Amazon Route 53 and GoDaddy mean record changes are applied directly at your DNS provider, and a full API lets you fold DMARC monitoring into existing workflows and tooling. Role-based access supports multiple team members, and multi-tenant Organisations with white-label reporting make the platform practical for MSPs and MSSPs managing large domain portfolios. Email spoofing is a business risk, not just a deliverability problem: attackers send invoices, payroll changes and phishing lures using your domain, and unprotected domains also see legitimate mail land in spam. Reaching p=reject stops that impersonation at the receiving mail server and improves deliverability for the mail you do want delivered. DMARC Busta is Australian-built, with transparent published per-domain pricing and no sales-call gate. A free forever plan covers a single domain, paid plans start at $19 per month, and every paid plan includes a 14-day free trial with no credit card required.
