In our increasingly connected world, satellite navigation systems like the Global Positioning System (GPS) have become indispensable. Whether you’re using navigation in your car, tracking delivery vehicles, coordinating logistics, or powering critical infrastructure systems, GPS plays a foundational role in modern life. But what happens when the integrity of that positioning system is compromised? Enter…
To set up DMARC for stronger email authentication and trust, correctly configure SPF and DKIM for every sending source, publish an initial monitoring DMARC policy (p=none) with aggregate/forensic reporting, analyze alignment and failure data, then progressively enforce to p=quarantine and p=reject while maintaining DKIM key hygiene and continuous monitoring. DMARC (Domain-based Message Authentication, Reporting, and…
Reduce the risk of blocking legitimate mail when enforcing a strict DMARC TXT record by rolling out p=reject gradually with the pct tag and ongoing rua/ruf monitoring, ensuring SPF/DKIM alignment with proper aspf/adkim settings, fully inventorying and validating all sending sources, deployingARC and SRS for forwarding/list scenarios, mitigating SPF/DNS pitfalls, coordinating vendors on keys and…
As email threats continue to grow, protecting your domain from phishing, spoofing, and fraudulent use of your brand is no longer a “nice-to-have” — it’s essential. And at the heart of strong email defense is DMARC — Domain-based Message Authentication, Reporting & Conformance. When implemented correctly, DMARC empowers domain owners to take control over how…
Cyber incidents this week focused on QR code phishing scams, neutralizing African cybercrime groups, and a major ransomware attack on a Ghanaian bank. While Kaspersky discovered an upsurge in QR code phishing, Operation Sentinel disrupted major cybercrime groups. Meanwhile, the Ghanaian bank suffered a major ransomware attack as cybercrooks managed to wipe away USD 120,000….
You can use DMARC lookup findings to fix authentication issues by turning aggregate and forensic reports into a prioritized map of failing senders, IPs, and domains; applying targeted SPF and DKIM alignment fixes; choosing relaxed vs strict alignment; rolling out DMARC policy from none to reject with measured thresholds; addressing forwarding, mailing lists, and third‑party…
Email marketing remains one of the most powerful digital communication channels available today — and that’s not going to change anytime soon. Despite new platforms and tools emerging constantly, email continues to deliver unmatched ROI, engagement, and direct audience access. But the key to success in email marketing isn’t the size of your list —…
Publish a TXT record at _dmarc.yourdomain.com with the value “v=DMARC1; p=none; rua=mailto:rua@dmarcreport.com; ruf=mailto:ruf@dmarcreport.com; fo=1; pct=100; adkim=r; aspf=r; sp=none” to begin DMARC monitoring for Office 365 safely and effectively. DMARC (Domain-based Message Authentication, Reporting and Conformance) builds on SPF and DKIM to tell receivers how to handle messages that fail authentication. In an Office 365 tenant,…
You can monitor, analyze, and protect your domain for free by implementing SPF, DKIM, and an initial p=none DMARC record with RUA/RUF pointing to DMARCReport, then using DMARCReport’s free analyzer to visualize alignment, tune policies toward quarantine/reject, handle third‑party senders, and integrate alerts and privacy controls at scale. Modern email authentication hinges on three open…
In today’s highly digital world, email remains one of the most essential communication channels for businesses — especially in the insurance industry. Unfortunately, as the industry embraces digital transformation, it also becomes an increasingly attractive target for cybercriminals leveraging email to defraud companies and unsuspecting policyholders alike. Email-borne insurance scams aren’t just an annoyance. When…
Companies rely on Autotask for sending emails about ticket updates, workflow alerts, invoices, system notifications, and more. Many of these emails are time and response-sensitive, which is why it’s important that domain owners integrate SPF, DKIM, and DMARC for their Autotask accounts. When these emails are not authenticated, receiving mailbox providers may treat them as…
To set up DMARC for your Google Workspace domain without breaking delivery, publish SPF (v=spf1 include:_spf.google.com ~all), generate and enable 2048‑bit DKIM in the Google Admin console, start with DMARC at p=none with rua/ruf to DMARCReport for monitoring, fix and align all third‑party senders via DKIM or aligned SPF, then progressively move to quarantine and…
This is the fourth edition of the month, and we have curated the top three cyber incidents that you must know about. We will begin the bulletin with the alleged threat attack on a French post office. Next, we will discuss the recent cyberattack on Romanian waters and try to understand the extent of damage…
Email security is among the most critical aspects of modern digital communications. Every year, organizations lose money, time, and reputation due to email fraud, phishing attacks, and domain spoofing. Studies show that even small breaches can cost businesses tens of thousands of dollars, while larger enterprises can lose millions per incident. With email-based threats rising…
Start by publishing a DMARC TXT record with aggregate (RUA) and optional forensic (RUF) destinations, ingesting those reports into a parser like DMARCReport, and then reading the aggregate XML fields—policy, alignment, SPF/DKIM results, source IP, and message counts—to correlate failures with your SPF/DKIM/DNS configuration and remediate misconfigurations before gradually tightening policy. DMARC is an authentication…
In today’s digital world, email remains one of the most powerful communication channels, but it is also one of the most abused. Every day, millions of malicious emails are sent to deceive recipients — from phishing to brand spoofing to targeted business email compromise (BEC). As these attacks evolve, so too must our defenses. At…
