Getting your logo to show in the inbox is no longer just a bonus. It is becoming an important way to build trust through emails and make your brand easy to recognize. When people see a familiar logo, they are more likely to open and trust the message. But once you decide to use BIMI,…
You can check your domain’s DMARC status by querying the DNS TXT record at _dmarc.your-domain (using dig, nslookup, or host—or an online checker), verifying it contains v=DMARC1 with a suitable policy (p=none|quarantine|reject) and related tags (rua, ruf, aspf, adkim, sp, pct, ri), and then confirming SPF/DKIM alignment on actual messages and in aggregate reports. DMARC…
Here are the top 4 cyber incidents from last week that every cyber enthusiast must be aware of. Steakhouse Financial, a crypto platform, was targeted by threat actors. A steep spike in cybersecurity threats against critical infrastructure systems in India is evident. The MEA region is experiencing a rise in fake shipment tracking scams. Meanwhile,…
The best practices for generating a DMARC record for a high-volume mailer are to publish a standards-compliant TXT at _dmarc.yourdomain with v=DMARC1; p=none (then ramp to quarantine and reject via pct), use relaxed alignment initially (aspf=r; adkim=r), set rua to a monitored mailbox or aggregator, be conservative with ruf (fo=1 or fo=d:s only if you…

Cybercriminals constantly develop new ways to exploit human behavior. While many organizations focus heavily on technical defenses like firewalls, endpoint protection, and encryption, attackers frequently target the weakest link in cybersecurity: people. One common social engineering tactic used by attackers is baiting. This technique relies on curiosity, temptation, and human psychology to trick victims into…
You can check whether your emails meet DMARC alignment by reading the message’s Authentication-Results headers to confirm that either SPF or DKIM passed in alignment with the visible From domain, validating your SPF/DKIM/DMARC DNS records with tools (dig, opendkim, DMARC analyzers), and continuously reviewing DMARC aggregate/forensic reports—ideally via DMARCReport—toverify alignment across all sources. Email authentication…
Introduction Enterprise email has evolved far beyond simple communication. Today, it is a mission-critical channel that supports marketing, customer engagement, financial transactions, and internal collaboration. However, as its importance has grown, so has its vulnerability. Cybercriminals increasingly exploit email as their primary attack vector, using techniques like spoofing and phishing to impersonate trusted brands. At…
Last week was replete with threat attacks that managed to create chaos and disrupt essential operations. Ohio-based Scioto County employees were targeted by phishing actors. A group of cybercrooks managed to mimic the FBI to target Tron blockchain users. Meanwhile, the RBI, India’s central bank and financial regulator, was hit as many as 61 million…
Every website you visit relies on a behind-the-scenes system that connects human-friendly domain names to machine-readable IP addresses. Without this system, accessing websites would require memorizing strings of numbers instead of simple URLs. At DMARCReport, we believe that understanding DNS fundamentals is essential not only for website functionality but also for email authentication, deliverability, and…
Handling patient data comes with serious responsibility. Under HIPAA, any information that can identify a patient must be protected at all times. This includes details like names, medical history, prescriptions, and insurance records. For businesses in healthcare and related industries, keeping this data secure is not optional. It is a basic requirement. Email, however, is…
Implementing strict DMARC alignment too quickly risks immediate delivery failures and bounces, widespread false negatives due to SPF/DKIM misalignment (especially across third-party senders and forwarding paths), DNS- and key-rotation–induced outages, uneven handling by major mailbox providers, and collateral damage across subdomains—risks that are avoidable with a phased rollout, rigorous RUA/RUF analysis, and tooling like DMARCReport…
Cyber threats continue to evolve as networks become more interconnected and data moves constantly between devices. While many organizations focus heavily on email-based threats such as phishing or domain spoofing, attackers also exploit weaknesses inside local networks. One of the most common techniques used to intercept network traffic is ARP spoofing. ARP spoofing is a…
Work looks different now, doesn’t it? Employees are the reason. Recent research from Gallup shows that six in ten employees prefer a hybrid work arrangement. No wonder the offices are now spread out, and so is the control IT once had. That makes it much harder to keep everyone secure. This shift has amplified a…
The best tools for checking DMARC alignment across multiple domains are DMARCReport (enterprise-grade bulk and automation), dmarcian, Valimail, Red Sift OnDMARC, Proofpoint Email Fraud Defense, EasyDMARC/PowerDMARC, Cloudflare DMARC Management, and open-source stacks like parsedmarc + ELK or OpenDMARC-based pipelines, all of which can automate alignment checks across hundreds to thousands of domains depending on plan…
A DMARC analyzer like DMARCReport can likely resolve your email spoofing problems if your aggregate DMARC (RUA) data shows concentrated SPF/DKIM failures from a few non-owned IPs or geographies, a low pass/alignment rate (typically below 85%), clear volume spikes during off-hours, and recurring alignment errors tied to specific third-party senders or misconfigurations—signals that a tool…
